2.5=15

5=30

Step-by-step explanation:

Multiply each original value by the scale factor

1×6=6

7×6=42

2.5×6=15 (2×6 + 6×0.5)

5×6=30

olga_2 [115]

The function is L = 10m + 50

Here, we want to find out which of the functions is required to determine the number of lunches L prepared after m minutes

In the question, we already had 50 lunches prepared

We also know that he prepares 10 lunches in one minute

So after A-lunch begins, the number of lunches prepared will be 10 * m = 10m

Adding this to the 50 on ground, then we have the total L lunches

Mathematically, that would be;

L = 10m + 50

Answer:

1. Option c

2. Option d

Step-by-step explanation:

This type of survey is includes a sample made up of voluntary responses. People only choose to or do not choose to respond.

This type of sampling method is most of the time unbelievable because generally only people with strong opinions about this particular questions will respond and it is usually towards the same direction as the question and this might not reflect the opinion of the whole population making the survey biased.

Anna11 [10]

A statistics student would like to estimate the average age of students at her college. she would like to be 85% confident that her estimate includes the actual college population mean

It means confidence level is 0.85.

After taking survey the estimate of population standard deviation is found as 4.5 years. The given margin of error is 0.5 years

The sample size is obtained using formula

n= (\frac{z_{\alpha/2} std}{ME} )^{2}

Where std = standard deviation

alpha = 1 -c = 1-0.85 = 0.15

z(α/2) = z(0.15/2) = z(0.075)

It is the critical value of z such that area above z and below -z is 0.075

Use z score table to find the probability exactly or very close to 0.075 and note the corresponding z score value.

In z score table there is no accurate 0.075 probability value. The close value is 0.0749 which corresponds to z score -1.44

For calculation we take positive z score value.

So we get z(α/2) =1.44

Using all the given values into formula

n = [(1.44 * 4.5) / 0.5]^2

n = 167.96

Rounding it to nearest integer we get n=168

The number of people need to surveyed is n=168
