Non proportional because 2×$2.40= $4.80 which is not equal to $3.50

Non proportional because 2.40 x 2 is not equal to 3.50. If it was proportional a half gallon would cost $1.75.

STALIN [3.7K]

C,D and F are correct.

C is what you would think of when reading it, you walked 12 and walked 1/4(12) more.

12 + 12(1/4) =

12 + 3 =

15

D is equal to C when simplified,

12(1+1/4) =

12 + 3 =

15

F is the same as the D, it just simplified the numbers in the parenthesis

12(1+1/4) =

12(4/4 + 1/4) =

12(5/4) =

15

The circumference of a circle is 6π m. What is the area, in square meters? Express your answer in terms of \piπ.
zaharov [31]

Answer:

Area = 9π sq. m.

Step-by-step explanation:

C = πd

6π = πd

d = 6

r = 3

A = πr^{2} = π3^{2} =  9π sq. m.

Suppose that we are testing a coin to see if it is fair, so our hypotheses are: H0: p = 0.5 vs Ha: p ≠ 0.5. In each of (a) and (
aleksley [76]

Answer:

H_0: p = 0.5\\H_a: p \neq 0.5

a. We get 56 heads out of 100 tosses.

We will use one sample proportion test  

x = 56

n = 100

\widehat{p}=\frac{x}{n}

\widehat{p}=\frac{56}{100}

\widehat{p}=0.56

Formula of test statistic =\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

                                       =\frac{0.56-0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}

                                       =1.2

refer the z table for p value

p value = 0.8849

a.  We get 560 heads out of 1000 tosses.

We will use one sample proportion test  

x = 560

n = 1000

\widehat{p}=\frac{x}{n}

\widehat{p}=\frac{560}{1000}

\widehat{p}=0.56

Formula of test statistic =\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

                                       =\frac{0.56-0.5}{\sqrt{\frac{0.5(1-0.5)}{1000}}}

                                       =3.794

refer the z table for p value

p value = .000148

p value of part B is less than Part A because part B have 10 times the number the tosses.
