Answer: y=3x+8

Step-by-step explanation:

(1 11) and (-2 2)

Find slope first "m"

M= y2-y1/x2-x1

M= 2-11/-2-1

M= -9/-3

M=3

Now use one the points with slope to find b

Y=mx +b with point (1,11) and slope 3.

Y=mx+b

11=3(1)+b

11=3+b

11-3=b

8=b

Now substitute to make equation

Y=3x+8

At a certain hospital, the probability of a child being born female is 0.51. If 80 babies are born on the a certain day, the pro

Ber [7]

Answer :

0.53

Step-by-step explanation:

Given the following :

Probability of female = probability of success on a single trial = 0.51

Number of babies = 80

Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)

The problem can be solved using the binomial probability function :

P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]

In other to save computation time, we can use the binomial probability calculator

Hence ; P(X > 40) = 0.527 = 0.53

A manager at a factory finds that in a random sample of 200 clocks, 15 are defective. What percent of the clocks are defective?

bogdanovich [222]

Answer:

Part A-7.5%

Part B-?

Part C-400 clocks

Step-by-step explanation:

part a-Write a sample ratio.-Divide the numerator by the denominator and multiply by 100.

part B-Use the sample ratio.-Multiply the sample ratio by the total number of clocks in the population.

Part C-Write a sample ratio.-Multiply the sample ratio by the total number of clocks in the population.
