What are the x-intercept and y-intercept of the graph of y=−1/2x+4 ? drag and drop your answers into the boxes. x-intercept: y-intercept:
a: -8
b: -4
c: -2
d: 2
e: 4
f: 8

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

In this problem we have

Step 1

Find the x-intercept

For

Substitute

The answer Part 1) is the option f

Step 2

Find the y-intercept

For

Substitute

The answer Part 2) is the option e

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
