When you write your measurement as the mean ± standard deviation, it means that you are displaying how far the data is spread out from the mean value. A normal distribution is one that is symmetrical and bell-shaped, where most of the data lies near the mean value.

When you write your measurement as the mean ± standard deviation, it means that you are displaying how far the data is spread out from the mean value. In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. When you add the standard deviation to the mean and also subtract the standard deviation from the mean, you get the upper and lower bounds of the range that contains about 68% of the data. This range is called one standard deviation.The value of the standard deviation indicates how much the data varies around the mean. If the standard deviation is high, then the data is widely spread out and vice versa. Additionally, when you write a measurement as the mean ± standard deviation, it is assumed that the data is normally distributed. A normal distribution is one that is symmetrical and bell-shaped, where most of the data lies near the mean value.

Answer:

12 chocolate bar cost rs 180

1 chocolate bar cost rs 180÷12

= rs 15

The cost of 30 chocolate bar cost = 15×30

=rs 450

If 12 chocolate bars cost Rs. 180, what would be the cost of 30 chocolate bars?

12 chocolate bars cost = Rs. 180

Cost of 30 chocolate bars = x

12:180 = 30:x

Means = Extremes

180 × 30 = 12 × x

( 3 × 4 = 12, 3 × 10 = 30)

It is expected to fall 2 inches of snow for each additional hour.

Step-by-step explanation:

As we want to find the amount of snow that will fall for each additional hour, we just need to use slope of the equation.

The slope is the value '2' that is together with the variable 't', and it means that if we increase the value of t by 1 unit, the value of d will increase by 2 units.

So we have that for each additional hour, it is expected to fall 2 inches of snow.

The required plant grew 9 centimeters in the sixth week.

Let x be the number of centimeters the plant grew in the sixth week.
To estimate x, we can use the formula for the mean (average) of a set of numbers:

mean = (sum of numbers) / (number of numbers)

We know the mean for 6 weeks is 9, so we can write:

9 = (13 + 6 + 10 + 5 + 11 + x) / 6

Multiplying both sides by 6, we get:

54 = 45 + x

Subtracting 45 from both sides, we get:

x = 9

Therefore, the plant grew 9 centimeters in the sixth week.

To determine which parent function would best model a given data set using finite differences or ratios, we need to analyze the pattern in the data points.

First, let's understand what finite differences and ratios are. Finite differences involve subtracting consecutive terms in the data set to find the differences between them. Ratios, on the other hand, involve dividing consecutive terms in the data set to find the ratio between them.

To use finite differences, calculate the differences between each pair of consecutive terms in the data set. If the differences are constant, it suggests a linear relationship, which can be modeled using the parent function y = mx + b (where m is the slope and b is the y-intercept). If the differences are the same for the first few terms and then change, it may indicate a quadratic relationship (y = ax^2 + bx + c).

To use ratios, calculate the ratios between each pair of consecutive terms in the data set. If the ratios are constant, it suggests an exponential relationship, which can be modeled using the parent function y = ab^x (where a is the initial value and b is the growth factor). If the ratios are the same for the first few terms and then change, it may indicate a logarithmic relationship (y = a + b log(x)).

Let's consider an example. Suppose we have the following data set: (1, 2), (2, 4), (3, 8), (4, 16).

Using finite differences, we calculate the differences: 2 - 1 = 1, 4 - 2 = 2, 8 - 4 = 4. Since the differences are not constant, a linear relationship can be ruled out. However, the second finite difference is constant (2), indicating a quadratic relationship.
Using ratios, we calculate the ratios: 4/2 = 2, 8/4 = 2, 16/8 = 2. The ratios are constant, indicating an exponential relationship.
Based on this analysis, we can conclude that the given data set is best modeled by an exponential parent function.

In summary, to determine which parent function best models a given data set using finite differences or ratios, we analyze the pattern of the differences or ratios. If they are constant, it suggests a linear or exponential relationship, respectively. If they are not constant, it may indicate a quadratic or logarithmic relationship, respectively.

Answer:

10 liters

Step-by-step explanation:

let sugar in  x liters of 60 % sugar syrup be equivalent to sugar in 40 liters of 45 % sugar syrup.

x×60 %=40×45%

60x=40×45=1800

x=1800/60=30

40-30=10

so 10 liters of 60 % sugar syrup be replaced with 10 liters of distilled water to make 40 liters of 45 % sugar syrup.

Answer:  The baker needs to pour off 10 liters of the solution and replace it with 10 liters of distilled water.

.6(40) = 24.  .45(40) = 18  24-18 = 6   6 = .6(10)  10 liters must be substituted.

Step-by-step explanation:

The original 60% solution contains 24 L syrup and 16 L water.

A 45% solution must contain 18 L syrup and 22 L water.

The difference in syrup is 6 L.  10 L of the 60% solution contains 6 L syrup.

After pouring off  10 L, the remaining  30 L will contain 18 L syrup and 12 L water.  

By adding 10 L water, the resulting solution is 18 L syrup and 22 L water.

18/40 = .45 which is the desired 45% syrup.

The length that will give a plot with the maximum area allowed is 6 meters.

To find the length that will give a plot with the maximum area, we need to use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width. In this case, we are given that the area is 45 square meters, and the width is 7.5 meters.

Substituting these values into the formula, we get:

45 = l(7.5)

To solve for l, we divide both sides by 7.5:

l = 45/7.5

To find the inverse function of F(x) = 2x - 3, we replace F(x) with y, swap the positions of x and y, and solve for y. The inverse function is f⁻¹(x) = (x+3)/2.

To find the inverse function of F(x) = 2x - 3, follow these steps

Replace F(x) with y. The equation now becomes y = 2x - 3.

Switch the positions of x and y, so the equation becomes x = 2y - 3.

Solve for y in terms of x. Add 3 to both sides: x + 3 = 2y.

Divide both sides by 2 (x + 3)/2 = y.

Replace y with the notation for the inverse function, f⁻¹(x): f⁻¹(x) = (x + 3)/2.

So, the inverse function of F(x) = 2x - 3 is f⁻¹(x) = (x + 3)/2.

The probability that the sample mean is between 43 and 52 minutes is

0.9098 or 91%

To unravel this issue, we got to utilize the central restrain hypothesis, which states that the test cruel of an expansive test estimate (n>30) from any populace with a limited cruel and standard deviation will be roughly regularly dispersed.

Given the cruel and standard deviation of the populace, able to calculate the standard blunder of the cruel utilizing the equation:

standard mistake = standard deviation / √(sample estimate)

In this case, the standard error is:

standard blunder = 11 / √(25) = 2.2

Another, we ought to standardize the test cruel utilizing the z-score equation:

z = (test cruel - populace cruel(mean)) / standard mistake

For the lower restrain of 43 minutes:

z = (43 - 46) / 2.2 = -1.36

For the upper restrain of 52 minutes:

z = (52 - 46) / 2.2 = 2.73

Presently, ready to utilize a standard ordinary conveyance table or a calculator to discover the probabilities comparing to these z-scores.

The likelihood of getting a z-score less than -1.36 is 0.0869, and the likelihood of getting a z-score less than 2.73 is 0.9967.

Hence, the likelihood of the test cruel being between 43 and 52 minutes is:

0.9967 - 0.0869 = 0.9098 or approximately 91D

The probability of the arrow landing on an odd number is the number of odd numbers divided by the total number of possible outcomes. Therefore, the probability of the arrow landing on an odd number is  0.5 or 50%.


To find the probability that the arrow will point at an odd number on a circular board with 8 equal parts, we'll first determine the total number of odd numbers present and then divide that by the total number of possible outcomes.

Step 1: Identify the odd numbers on the board. They are 1, 3, 5, and 7. The game consists of spinning the arrow on a circular board with 8 equal parts, which means there are 8 possible outcomes or numbers. Since we want to know the probability of landing on an odd number, we need to count how many odd numbers are on the board. In this case, there are four odd numbers: 1, 3, 5, and 7.

Step 2: Count the total number of odd numbers. There are 4 odd numbers.

Step 3: Count the total number of possible outcomes. Since the board is divided into 8 equal parts, there are 8 possible outcomes.

Step 4: Calculate the probability. The probability of the arrow pointing at an odd number is the number of odd numbers divided by the total number of possible outcomes.

Probability = (Number of odd numbers) / (Total number of possible outcomes)
Probability of landing on an odd number = Number of odd numbers / Total number of possible outcomes
Probability of landing on an odd number = 4 / 8

Step 5: Simplify the fraction. The probability of the arrow pointing at an odd number is 1/2 or 50%.

So, the probability that the arrow will point at an odd number is 1/2 or 50%.
