Whats the vertex of (0, 0) and (20, 15)

this might be little bit diffult but hope it helps :)

Step-by-step explanation:

the equation of a parabola in vertex form is

Y = a(x−h)2+k

Where the (h,k)  are the coordinates of the vertex and is a multiplier

Here (h,k) = (0,0) thus

Y = ax2

to find a subsitiude (-1, -4) into a equation

-4 = A

So y = -4x 2

So take this infomation and put it into the (0,0) and (20,15)

Hope this helps :) let me know if this isnt right

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;
