We need to use the formula to find Margin of Error but through the sample proportion, that is

We will use a 95% confidence interval, that is a z value of 1.96 (Search in a Normal distribution table)
A) For A our
(proportion) is equal to 0.45. So applying the formula,


B) We make the same of point A, but change our proportion to 0.35


c) We need to calculate the SE through proportion for 0.1, that is

Then our Error is given by,



Answer:
w = 36 cm
L = 27 cm
Step-by-step explanation:
I am translating and I see that perimeter of rectangle is 126 cm and the base (assuming Length) is (3/4) the height.
P = 2(l+w)

Divide both sides by 2, so you get
(3/4)w+(4/4)w=(126/2)
(7w/4)=63
Multiply both sides by 4,
7w=252, then divide both side by 7,
w = 36, Width is 36 cm, so Length is (3/4), which is L = 27 cm
6:3 = 6/3 = 2
13 to 4 = 13:4 = 13/4 = 3.25
19/2 = 9.5
15 to 10 = 15:10 = 15/10 = 1.5
8:2 = 8/2 = 4
From the least to the greatest:
15 to 10 , 6:3, 13 to 4, 19/2
I hope this explains it.
Answer:
A
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x - 2 - (2x + 1)
= 3x - 2 - 2x - 1 ← collect like terms
= x - 3 → A
Answer:
I am going to have to go with B. (How many text messages do you send each day?) This will get you the data needed because it is specific. D would also work but I went with C because D is less informative and less specific about how often people use their phones. Hope that this helped! Please tell me if you have any more questions! Have a great day!
