What is the value of b in the equation y= 20 + 15x? Find the answer.

yes correct

Step-by-step explanation:

b = 20

Step-by-step explanation:

Using the slope-intercept form, y = mx + b, as a reference:

slope = m

y-intercept = b

In your given linear equation, y= 15x + 20:

The slope,  m = 15

And the y-intercept = 20.

The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.

Therefore, the value of the y-intercept, b, in the given equation is 20.

step-by-step explanation:

just keep timing it by 4.

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;
