Answer:

x is 20 and y is 23

Step-by-step explanation:

Answer:

x = 15

y = 4

Step-by-step explanation:

In a triangle a line parallel to any of the sides of the triangle divides the remaining two sides in the proportion. Therefore,

\( \frac{12}{y} = \frac{x}{5} = \frac{18}{6} \\ \\ \frac{12}{y} = \frac{x}{5} = \frac{3}{1} \\ \\ \implies \:\frac{x}{5} = \frac{3}{1} \\ \\ x = 5 \times 3 \\ \\ x = 15 \\ \\ \\ \frac{12}{y} = \frac{3}{1} \\ \\ 3y = 12 \\ \\ y = \frac{12}{3} \\ \\ y = 4\)

Answer:

Let x represents the number of children in the Broadway musical,

Since, The number of women who attended the event was 5 more than 3 times the number of children,

⇒ The number of women = 3x + 5

Also, the number of men was 3 less than 4 times the number of women,

⇒  The number of men = 4(3x+5)-3 = 12x + 20 - 3 = 12x + 17

Thus, the total number of persons = x + 3x + 5 + 12x + 17 = 16x + 22

According to the question,

16x + 22 = 2838

Which is the required equation,

Subtract 22 on both sides,

16x = 2816 ⇒ x = 176

Hence, the total number of children = 176

The number of women = 3 × 176 + 5 = 533

And, the number of men = 12 × 176 + 17 = 2129

the equation of the least squares regression line is y = 0.2x + 13.1. This equation represents the line that provides the best fit to the given data points.

The least squares regression line represents the line that best fits a given set of data points. It is determined by finding the slope and intercept of the line.

Given:

x-bar = 15 (mean of x values)

sx = 2 (standard deviation of x values)

y-bar = 17.1 (mean of y values)

sy = 3 (standard deviation of y values)

r = 0.2 (correlation coefficient)

The slope of the regression line, denoted as b, can be calculated using the formula:  b = r × (sy / sx)

Substituting the given values: b = 0.2 * (3 / 2) = 0.3

The intercept of the regression line, denoted as a, can be calculated using the formula: a = y-bar - b × x-bar

Substituting the given values: a = 17.1 - 0.3 × 15 = 13.1

Answer:

x ≤ -6

Step-by-step explanation:

This has a close circle, meaning it will have an equal sign.

The line goes to the left of -6, meaning x < -6

So, our inequality is x ≤ -6

Based on the line of best fit, the approximate maximum depth of a lake that has 31 miles of shoreline is; 142.968 ft

The line of best fit is defined as a straight line which is drawn to pass through a set of plotted data points to give the best and most approximate relationship that exists between such data points.

Now, we are given a table of values that shows the total shoreline in miles which will be represented on the x-axis and then the maximum depth of several area lakes which will be represented on the y-axis.

However, when the geologist found the graph, she arrived at an equation of best fit as;

y = 4.26x + 10.908.

Thus, for 31 miles of shoreline, the approximate maximum depth is;

Approximate maximum depth = 4.26(31) + 10.908.

Part A: JoAnn's team collects 3m magazines.

Part B: The number of magazines (m) = 218 magazines.

Part A: To represent the total number of magazines JoAnn's team has collected, we can set up an equation. We know that JoAnn's team collected 3 times as many magazines as Clarissa's team. Therefore, we can set up the equation 3m = 654, where m represents the number of magazines that Clarissa's team collected. Part B: To solve the equation, we can divide both sides by 3. This gives us m = 218. This means that the number of magazines (m) Clarissa's team collected is 218 magazines.  In conclusion, Clarissa's team collected 218 magazines, and JoAnn's team collected 3 times as many magazines, which is 654 magazines.

Answer:

\(x=4,\:x=-\frac{3}{2}\)

Step-by-step explanation:

\(x\left(2x-5\right)\)

Apply the distributive law.

\(=x\cdot \:2x-x\cdot \:5\)
\(=2x^2-5x\)
\(2x^2-5x=12\)
Subtract 12 from both sides.
\(2x^2-5x-12=12-12\)
\(2x^2-5x-12=0\)
Now, apply the quadratic formula.
\(x_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-12\right)}}{2\cdot \:2}\)
\(x_{1,\:2}=\frac{-\left(-5\right)\pm \:11}{2\cdot \:2}\)

Answer:

2500 pieces of blank paper measuring 8 inches by 10 inches would need to be taped together.

Step-by-step explanation:

To determine how many 8-inch by 10-inch pieces of paper are needed to fit the enlarged map, we need to calculate the dimensions of the enlarged map.

The original map had a scale of 1 inch = 50 miles. Since the map was 8 inches by 10 inches, the actual area it represented was:

8 inches x 50 miles/inch = 400 miles (width)

10 inches x 50 miles/inch = 500 miles (height)

Now, we have a new scale of 2 inches = 25 miles. To find the dimensions of the enlarged map, we can use the ratio of the scales:

2 inches / 1 inch = 25 miles / x miles

Cross-multiplying, we get:

2x = 1 inch x 25 miles

2x = 25 miles

x = 25 miles / 2

x = 12.5 miles

So, the enlarged map will represent an area of 400 miles (width) by 500 miles (height), using the new scale of 2 inches = 25 miles.

To determine how many 8-inch by 10-inch pieces of paper are needed, we divide the dimensions of the enlarged map by the dimensions of each piece of paper:

Number of paper pieces needed = (400 miles / 8 inches) x (500 miles / 10 inches)

Number of paper pieces needed = 50 x 50

Number of paper pieces needed = 2500

Therefore, to fit the entire enlarged map, approximately 2500 pieces of blank paper measuring 8 inches by 10 inches would need to be taped together.

Assume Keesha has d dimes, so she has d + 10 quarters

Total money Keesha has is (d+10)*.25 + d*.1 = 11.25

or 0.35d + 2.5 = 11.25

Solving for d , d = 25

So Keesha has 25 dimes and 35 quarters, total of 60 coins

The number of dimes and quarters Keesha has if, Keesha has 10 more quarters than dimes are 25 and 35 respectively.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Step-by-step explanation:

So, the cab ride was 2 miles long.

Cost refers to the total amount of money, time, effort, or resources required to produce or obtain something. It is the value of the inputs used to create a product or provide a service. In business, cost is a crucial factor in determining profitability, as it directly affects the price of goods and services and ultimately the revenue earned by a company. There are various types of costs, such as fixed costs, variable costs, direct costs, indirect costs, and opportunity costs. Understanding the costs associated with a particular activity or project is important for effective decision making and resource allocation.

Given by the question.

To solve this problem, we need to use the information provided to find out how many miles the cab ride is. Then we can use the rate of $3.20 per mile to calculate the cost of the distance traveled, and add the initial $4.50 fee to get the total cost of the ride.

Let's start by subtracting the initial fee from the total cost of the ride to find the cost of the distance traveled:

$10.90 - $4.50 = $6.40

This means that the distance traveled costs $6.40. We can now use the rate of $3.20 per mile to find out how many miles were traveled:

$6.40 ÷ $3.20 per mile = 2 miles

Answer:

35 and 10

Step-by-step explanation:

Let m and n be the numbers

m  is 5 more than 3 times n can be written as

m = 3n + 5    ... (1)

Sum of numbers is 45 so m + n = 45 .or

m = 45 - n ... (2)

Equating RHS of (1) and (2) gives us

3n + 5 = 45 - n

Collecting like terms

3n + n = 45 -5

4n = 40

n = 10

Therefore m = 45-10 = 35

Quick Check

In (1) substitute for m and n,

LHS is m = 35

RHS = 3 * 10 + 5 = 35

Step-by-step explanation:

Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.

To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:

SE = sqrt((s1^2 / n1) + (s2^2 / n2))

Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:

SE = sqrt((47^2 / 49) + (4.3^2 / 53))

Next, we calculate the t-statistic using the formula:

t = (x1 - x2) / SE

Where x1 and x2 are the sample means. Plugging in the values, we have:

t = (239 - 21.1) / SE

We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.

In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.

Therefore, the correct answer is:

B. Male and female high school students have different exam scores.
