Answer:

x= 21

y= 3

z= 21

Step-by-step explanation:

Let the center be O,

=> Triangle AOD is an Isosceles triangle so AO≅DO, "21 = x"

=> Line AC is divided in two equal parts by the center so if AO= 21 then

7y = 21, and thus "y = 3"

=> BOC is also an Isosceles triangle so CO ≅ BO, if CO = 21 (7y → 7*3) then so will be BO. Therefore "z = 21"

Peter says that 3/4 of a pizza is always the same as 6/8 of pizza. Nadia says that while they are equivalent fractions, 3/4 and

Whitepunk [10]

Nadia Is correct I believe, Because if a pizza is cut into 8 slices each slice is going to be smaller. but if it were to be cut into fourths it would be bigger. They are indeed equivalent but still never the same in size.

Suppose that 76% of americans prefer coke to pepsi. a sample of 80 was taken. what is the probability that at least seventy perc

vladimir2022 [97]

The standard deviation of the sample proportion is:
$\sqrt{ \frac{0.76(1-0.76)}{80}} =0.048$
The z-score for 0.7 is:
$z= \frac{0.7-0.76}{0.048} =-1.25$
Reference to a standard normal distribution table shows that the probability that at least 70% of the sample prefers coke to pepsi is 0.8944 or 89.44%.
