Answer:

first pic: A and C

second pic: i dont know for A, B = w + 1.4, C = 3y = 5.1, D = z + 1/3 = 1/2

third pic: a. 2x = 14.62 b. there are 2 x's on one side, and 1 number on the other, which can be taken as the answer to 2x. if we can do 2x = 14.62, we can do 14.62 divided by 2 to get the other number x, 14.62 divided by 2 = 7.31. c. i don't know

after this

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework? WILL MARK
Bess [88]
Assuming that x is the amount of hours spent doing homework:

Plug in 3 for x

y = 8(3)+40, y=64

That means that since a y value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.

A medical website states that 40% of U.S. adults are registered organ donors. A researcher believes that the proportion is too h
Marat540 [252]

Answer:

P value is 0.1932

conclusion is that find value P greater than hypothesis test at the 0.05 level

Step-by-step explanation:

Given data

registered organ donors P  = 40%

sample n = 200

registered organ donors x = 74

hypothesis test α = 0.05

to find out

P-value and state a conclusion

solution

we take a trail p less than 40 % i.e 0.40

so p = x/n

p = 74 / 200 = 0.37

so we find here Z value  i.e

Z = p - P / √(PQ/n)

here Q = 1-p = 1-0.40 = 0.60

so Z = 0.37 - 0.40 / √(0.40×0.60/200)

Z = - 0.866

so p value for Z (-0.866) from z table

P value is 0.1932

and conclusion is that find value P greater than hypothesis test at the 0.05 level
