Answer:

Q = (4, - 1)

Step-by-step explanation:

DF is the diameter of the circle with center Q.

So, Q is the midpoint of DF.

By mid point formula.

Q =  \bigg( \frac{1 + 7}{2},  \:  \:  \frac{3 - 5}{2} \bigg) \\  \\ Q =  \bigg( \frac{8}{2},  \:  \:  \frac{ - 2}{2} \bigg) \\  \\ Q = (4, \:  \:  - 1)

A random sample is to be selected from a population that has a proportion of successes p=.60. When n=400, what is the probabilit
Nata [24]

Answer:

0.45134

Step-by-step explanation:

Given that :

p = 0.6

n = 400

Probability that sample. Proportion falls between 0.59 and 0.62

Using Normal approximation :

Mean (m) = n * p = 400 * 0.6 = 240

Standard deviation (s) = sqrt(pq/n)

q = 1 - p = 1 - 0.6 = 0.4

s = sqrt((0.6 * 0.4) / 400) = 0.0244948

P(0.59 < p < 0.62) :

(x - m) / s

P((0.59 - 0.6) / 0.0244948) < p < P((0.62 - 0.6) / 0.0244948)

P(Z < −0.408249) < p < P(Z < 0.8164998)

Using the Z probability calculator :

0.79289 - 0.34155 = 0.45134

1) A square has a side length of 10 inches. What is the perimeter?
antiseptic1488 [7]

Answer:

1) 40

2)9x-12

3)42

Step-by-step explanation:

1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40

2) Simply add these values together to get 9x-12

3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42

the ramirez family comes home from vacation to find their mailbox overflowing with mail. there are 6 more magazines than there a
nirvana33 [79]

Answer:

9 magazines

Step-by-step explanation:

To solve this problem you will want to work backwards. Start with the junk mail. There is 18 junk mail and if there are 1/3 as many bills as junk mail then you will need to multiply 18 * 1/3. This equals 6 bills. If there is twice as many bills as letters then you will need to divide bills(6) by 2 which equals 3. If there are 6 more magazines than letters then you need to add 6 to the letters (3). 3 + 6 = 9
