Step-by-step explanation:

Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Answer:

36 people

Step-by-step explanation:

240 x 0.15 = 36

The number of each type of coins are as follows:

q = 15 quarters.

d = 30 dimes.

n = 25 nickels.

In order to solve this word problem, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let d represent the number of dimes.

Let q represent number of quarters.

Let n represent number of nickels.

Let T represent total number of coins.

Note: 1 quarter is equal to 0.25 dollar, 1 nickel is equal to 0.5 dollar, and 1 dime is equal to 0.1 dollar.

Translating the word problem into an algebraic equation, we have;

Dimes; d = 2q     .....equation 1.

Nickels; (70 - (q + 2q)) = (70 - 3q)     .....equation 2.

Total coins; T = n + d + q

0.5(70 - 3q) + 2q(0.1) + q(0.25) = 8.00

Multiplying all through by 100, we have:

5(70 - 3q) + 2q(10) + q(25) = 800

350 - 15q + 20q + 25q = 800

350 + 30q = 800

30q = 800 - 350

30q = 450

q = 450/30

q = 15 quarters.

For the number of dimes, we have:

Dimes, d = 2q

Dimes, d = 2(15)

Dimes, d = 30 dimes.

For the number of nickels, we have:

Nickels, n = (70 - 3q)

Nickels, n = (70 - 3(15))

Nickels, n = (70 - 45)

Nickels, n = 25 nickels.

There are 41 votes in total in the weighted voting system

What is weighted voting ?

Generally, a weighted vote occurs in policy or law making bodies where representatives have varying voting powers (weighted vote) according to how many principals or citizens they represent, or by the number of principals they represent.

The weighted voting situation is given as

[21: 23, 14, 4]

A weighted voting situation is represented as

[q: w1, w2......, wn]

Where q represents the quota and the w1 to wn are the votes

The total number of votes is calculated as

Total = w1 + w1 + .... + wn

So, we have

Total = 23 + 14 + 4

Evaluate the sum

Total = 41

Answer:

the answers is 160

you take 180-120=60

m<6= 60

Step-by-step explanation:

The first five terms of the sequence are 27, 22, 17, 12, and 7.

To find the first five terms of the sequence given by a₁=27 and d=-5,

we can use the formula for the nth term of an arithmetic sequence:

\(a_n=a_1+(n-1)d\)

Substituting the given values, we have:

\(a_n=27+(n-1)(-5)\)

Now, we can calculate the first five terms of the sequence by substituting the values of n from 1 to 5:

\(a_1=27+(1-1)(-5)=27\)

\(a_1=27+(2-1)(-5)=22\)

\(a_1=27+(3-1)(-5)=17\)

\(a_1=27+(4-1)(-5)=12\)

\(a_1=27+(5-1)(-5)=7\)

Therefore, the first five terms of the sequence are 27, 22, 17, 12, and 7.

Increasing the problem size leads to a decrease in parallel efficiency when T_overhead grows faster than T_serial.

Let's analyze the two cases separately:

Case 1: T_overhead grows more slowly than T_serial

In this case, as the problem size increases, the dominant factor affecting the total execution time is T_serial, which represents the time it takes to execute the computation sequentially. Since T_overhead grows at a slower rate, it has less impact on the total execution time compared to T_serial.

As the problem size increases, the parallel efficiency (E_parallel) can be calculated as E_parallel = T_serial / (T_serial + T_overhead). Since T_overhead is relatively small compared to T_serial, the value of T_serial dominates the denominator, resulting in a higher value of E_parallel.

Therefore, increasing the problem size leads to an increase in parallel efficiency when T_overhead grows more slowly than T_serial.

Case 2: T_overhead grows faster than T_serial

In this case, as the problem size increases, the impact of T_overhead becomes more significant compared to T_serial. As a result, the total execution time is increasingly influenced by T_overhead rather than T_serial.

When calculating the parallel efficiency (E_parallel = T_serial / (T_serial + T_overhead)), the increasing value of T_overhead in the denominator outweighs the impact of T_serial. As a result, the value of E_parallel decreases as the problem size increases.

Therefore, increasing the problem size leads to a decrease in parallel efficiency when T_overhead grows faster than T_serial.

In summary, when T_overhead grows more slowly than T_serial, the parallel efficiency increases as the problem size increases. Conversely, when T_overhead grows faster than T_serial, the parallel efficiency decreases as the problem size increases.

The missing Value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

The missing value that, when multiplied by 5/3^4, gives the result of 5^4, we can set up the equation:

(5/3^4) * x = 5^4

To solve for x, we can simplify both sides of the equation. First, let's simplify the right side:

5^4 = 5 * 5 * 5 * 5 = 625

Now, let's simplify the left side:

5/3^4 = 5/(3 * 3 * 3 * 3) = 5/81

Now we have:

(5/81) * x = 625

To solve for x, we can multiply both sides of the equation by the reciprocal of 5/81, which is 81/5:

(81/5) * (5/81) * x = (81/5) * 625

On the left side, the fraction (81/5) * (5/81) simplifies to 1, leaving us with:

1 * x = (81/5) * 625

Simplifying the right side:

(81/5) * 625 = 13125

Therefore, the missing value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

Answer:

$1.70

Step-by-step explanation:

If $8.50 is for 5 ounces divide both sides by 5. 5/5=1 and 8.50/5 is 1.70. So $1.70 is the price per ounce.

The dollar per ounce is 1.7 if $8.50 is for 5 ounces.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given $8.50 for 5 ounces.

To determine the dollars per oz.

Since $8.50 is for 5 ounces

We can write this as a ratio :

$8.50: 5 ounces = dollars  : ounces

⇒ 8.5/5 = the dollars per oz

We have to divide by 5, and we get

⇒ the dollar per ounce = 1.7

Thus, the dollar per ounce is 1.7.

Let's call:

x = time Stanley swam yesterday.

We know he ran for half an hour longer than he swam, thus the time he ran was:

x + 0.5 = time Stanley ran yesterday

We also know he biked for twice the time he ran, thus:

2(x + 0.5) = time Stanley biked yesterday.

The distance covered by Stanley when swimming is

2.5*x

The distance covered by Stanley when running is:

9*(x+0.5)

The distance covered by Stanley while biking is:

16*2*(x + 0.5) = 32(x + 0.5)

The total distance is 64 miles, thus:

2.5*x + 9*(x+0.5) + 32(x + 0.5) = 64

Operating:

2.5x + 9x + 4.5 + 32x + 16 = 64

Simplifying:

43.5x + 20.5 = 64

Subtracting 20.5:

here is a 19.8% probability that for a random sample of 18 days, it will rain exactly 4 of those days.

The meteorologist can use probability to determine the likelihood of it raining on a certain number of days in a random sample of 18 days. Based on the past year's records, the probability of it raining on any given day is 21/365, or approximately 0.0575. Using the binomial distribution formula, the probability of it raining exactly 4 times in a random sample of 18 days is:

P(4) = (18 choose 4) * (0.0575)^4 * (1 - 0.0575)^(18 - 4)
P(4) = 0.198

Therefore, there is a 19.8% probability that for a random sample of 18 days, it will rain exactly 4 of those days.

This probability is based on the assumption that the weather patterns will remain similar to the past year's records.

Step-by-step explanation:

A dilation or combination of stiff movements and dilations constitutes a similarity transformation.

Similar figures don't always have to have the same size but share the same form.

A transition called a dilation keeps shape but not size. So a dilatation is a motion that is not rigid. A dilation or combination of stiff movements and dilations constitutes a similarity transformation. If and only if a similarity transformation translates one of the geometric figures onto the other, then two figures are said to be similar. Similar figures don't always have to have the same size but share the same form.

Similarity transformations include translation, reflection, rotation, and dilation. Rotation, reflection, and translation retain both size and form since they are rigid movements, whereas dilation just makes sure that the shape is preserved.

The direct condition relating the cost to the number sold is;'Y = 766.98 - 70.38X'Now, substitute the given cost of $1.80, to find the anticipated interest. The anticipated demand for mocha latte coffees will be 1,107.3 cups. Y = 766.98 - 70.38(1.8) Y = 1119.354.

1,107.3 cups of mocha latte coffee are anticipated to be consumed at a cost of $1.80 per cup. How can the predicted demand for mocha latte coffees be calculated? Simple linear regression tries to find a formula that can be used to predict values of one variable from another for forecasting purposes. There must be a causal connection between the variables in order to accomplish this. Given that the cost of a cup of mocha latte coffee is $1.80, the task at hand is to estimate the anticipated demand. Therefore, the issue can be resolved by substituting the given price for the linear equation describing the price and the number of sold using simple linear regression.

The following is a simple linear regression equation: Y = a + bX, where Y is the dependent variable (number of cups sold) and X is the independent variable (price per cup).a is the Y-intercept, which is a constant term, and b is the slope of the line, which is the regression coefficient. To begin, use the formula b = (Xi - X)(Yi - ) / (Xi - X)2, where Xi and Yi are the respective The variables' sample means are X and. We get b = [(2.6 - 2.71)(770 - 575.5) + (3.6 - 2.71)(515 - 575.5) + (2.1 - 2.71)(990 - 575.5) + (4.1 - 2.71)(250 - 575.5) + (3 - 2.71)(315 - 575.5) + (4 - 2.71)2]b = -335.74 / 4.77b = -70.38 Subbing the given values,We get,a = 575.5 - (- 70.38 × 2.71)a = 766.98Therefore, the direct condition relating the cost to the number sold is;'Y = 766.98 - 70.38X'Now, substitute the given cost of $1.80, to find the anticipated interest.

(c) Two assumptions necessary for the validity of the ANOVA are:

1. Independence: The observations within each group and between groups should be independent of each other. This means that the value of one observation should not be influenced by or related to the value of another observation.

2. Homogeneity of variances: The variances within each group should be roughly equal. This assumption, also known as homoscedasticity, ensures that the variability in the dependent variable is similar across all groups.

(d) The company uses leaflets of four different designs to promote its printers. To assess the impact of leaflet design on sales, an ANOVA is performed. The null hypothesis states that the mean sales are equal across all leaflet designs, while the alternative hypothesis suggests at least one mean is different.

By comparing the computed F-statistic with the critical F-value at a significance level of 0.05, the ANOVA determines whether there is sufficient evidence to reject the null hypothesis. If the p-value is less than 0.05, it indicates a significant difference among the leaflet designs.
