Answer:
n = 23
x = 17
p = 0.50
Step-by-step explanation:
For a binomial experiment we have the following variables:
<u>1) Number of trials or Sample size:</u>
The number of trials is represented by n. In the given scenario 23 adults were asked about their favorite pizza, so the number of trials in this will be 23. Thus
n = 23
<u>2) Number of success</u>
The number of success is denoted by x. Number of success indicates that how many trials resulted in the favorable outcome. In the given case, choosing a sausage pizza is a success. Since 17 adults chose the sausage, so
x = 17
<u>3) Probability of success on single trial</u>
This is represented by p. It is stated that 50% adults say sausage is their favorite pizza. So,
p = 50% = 0.50
Answer: C
Step-by-step explanation:
Less than or more than without "or equal" means that the dot is not shaded, otherwise it is.
So the answer is C
Answer:
a
Step-by-step explanation:
Answer:
x =7, y = 3
Step-by-step explanation:
We substitute the value of x in terms of y (given) into the equation.
Then we solve for y and plug in the value of y back into the equation for the value of x to find x.
33.C
34.C
Those are the answers
