Which of the following has a y-intercept of 3 y=3x+2 or x=3or y=2x+3 or y=x

We conclude that the equation y=2x+3 has a y-intercept of 3.

Step-by-step explanation:

The slope-intercept form of the line equation

where

Given the equation

y = 3x+2

comparing with the slope-intercept form y = mx+b

The slope-intercept of y = 3x+2 is: 2

Given the equation

x=3

Does not have a y-intercept.

Given the equation

y=x

comparing with the slope-intercept form y = mx+b

The slope-intercept of y=x is: 0

Given the equation

y=2x+3

comparing with the slope-intercept form y = mx+b

The slope-intercept of y=2x+3 is: 3

Thus, we conclude that the equation y=2x+3 has a y-intercept of 3.

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;
