Answer:

2/7 divided 7= 2/14=1/7

Step-by-step explanation:

In these kind of problems you keep,change,flip

2/7 stays the same the division symbol change to a multiplaction sign and since the 7 is a whole we have to change it to 7/1 and flip it so the answer is   2/14 and since 2 goes into 14 we can simply when change to 1/7

HHope this helps :)

Find the equation of the circle with center at (0, 0) and diameter of 18.
Agata [3.3K]

Answer:

{x}^{2}  +  {y}^{2}  = 81

Step-by-step explanation:

The general for for the equation of a circle is

{(x - a)}^{2}  +  {(y - b)}^{2}  = {r}^{2}

Where a is the x coordinate of the centre, b is the y coordinate of the centre and r is the radius.

In your case, a=0, b=0, r=9

Substituting these values into the general form gives the answer.

Answer:

  D. (1.6 + 3) × (4 − 2) ÷ 2

Step-by-step explanation:

The order of operations requires that multiplication and division be done in order of appearance, left to right, before addition and subtraction. Operations in parentheses take priority.

To get 4.6, you need to add 3 to 1.6. The various forms of 3×4-2÷2 all give 12-1 = 11, not 3.

The grouping that gets it right is ...

  (1.6 + 3) × (4 − 2) ÷ 2

  = 4.6×2÷2

  = 9.2÷2

  = 4.6

Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

\mu=\pi=0.328

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094

B) The fraction with sample proportion of 0.45 or higher is

z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714

C) The fraction with sample proportion of 0.20 or lower is

z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208
