The value of in the complementary angles y is 3
<em>Your question is not complete, it seems to be missing the following information,</em>
(9y+5)° + 58° are complementary angles, solve for the value of y
Complementary angles add up to 90 degrees. That is the sum of the two given angles must sum up to 90 degrees.
- The first given angle = (9y+5)°
- The second given angle = 58°
- The sum of the two angle = (9y+5)° + 58° = 90°
Simplify the equation as follows to determine the value of y;
9y + 5 + 58 = 90
9y + 63 = 90
9y = 90 - 63
9y = 27
Thus, the value of in the complementary angles y is 3

Answer:
B. 1:7
we have 25 individuals that are randomly selected out of 100 shoppers leaving a local bedding store, and we know that each of the shoppers has the SAME probability of answering yes to having made a purchase, so we can assume that the probability that a person or a shopper made a purchase is 1 / 12.
Also we know that we selected 25 individuals, so there are 25 shoppers that can say yes, that means our sample size N is 25.
and you want to know the probability that exactly 4 of the 25 shoppers made a purchase
this is a binomial distribution because we can see that we have a sample size n = 25, we have a proportion of success, 1/2to say yes to having made a purchase and we can say that each shopper is independently from the other shoppers.
So the binomial equation is given by: (check the attached image)
so we know that we want P(X=4) because we want to know exactly 4 out of 25.
so n is 25, p is 1/2 and x is 4 so substituting the values into the equation we will get:
P(X=4) = 25C4 * (1/2)^4 * (1 - 1/2)^(25-4)
P(X=4) = 12650 * 0.0625 * 0.000000476
P(X=4) = 0.000377
the probability that exactly 4 of the 25 shoppers made a purchase is....0.00010243
Answer:
its simple just divide the value whole piece by the value of Cutted pieces
Step-by-step explanation:
we get
