Answer:

12) just plug in the numbers to the equation

C = (-4,5) D = (-2,3)

11) 8.426

10) 3, 4, 5

level 3-4) 24

Step-by-step explanation:

11) 7^2 + 11^2 = c^2

49 + 22 = c^2

√71 = √c^2

c = 8.426

10) 3, 4, 5 is a special right triangle but

3^2 + 4^2 = 5^2

25 = 25

level 3-4)

7^2 + h^2 = 25^2

49 + h^2 = 625

√h^2 = √576

h = 24

Eve plays basketball. She makes 4 free throws for every 3 free throws that she misses. If she missed 36 free throws at her last

zaharov [31]

The ratio of free throws to miss throws = 4/3

Miss throws = 36
So, free throws would be = 36 * 4/3 = 48

So, your final answer is 48

Hope this helps!

Assume that women's heights are normally distributed with a mean given by mu equals 62.5 in, and a standard deviation given by

kirza4 [7]

Answer: a) The probability is approximately = 0.5793

b) The probability is approximately=0.8810

Step-by-step explanation:

Given : Mean : $\mu= 62.5\text{ in}$

Standard deviation : $\sigma = \text{2.5 in}$

a) The formula for z -score :

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

Sample size = 1

For x= 63 in. ,

$z=\dfrac{63-62.5}{\dfrac{2.5}{\sqrt{1}}}=0.2$

The p-value = $P(z$

$0.5792597\approx0.5793$

Thus, the probability is approximately = 0.5793

b) Sample size = 35

For x= 63 ,

$z=\dfrac{63-62.5}{\dfrac{2.5}{\sqrt{35}}}\approx1.18$

The p-value = $P(z$

$= 0.8809999\approx0.8810$

Thus , the probability is approximately=0.8810.

Ken has read 1/3 of his book what fraction of his book is left to read?

Stells [14]

Answer:

2/3

Step-by-step explanation:

fraction of book already read = 1/3

fraction which represents whole book = 1 = 3/3

fraction of remaining book = fraction of whole book - fraction of book already read

= 1 - 1/3

= 3/3 - 1/3

= (3-1) /3

= 2/3

In which quadrant does O lie if the following statements are true:<br> cos 0 < 0 and cscO > 0

Olin [163]

Answer:

2nd quadrant.

Step-by-step explanation:

$\text{Given that,}~ \cos \theta < 0~ \text{and}~ \csc \theta > 0.}\\\\\text{So,}~\cos \theta ~ \text{is negative and}~ \csc \theta ~ \text{is positive.}\\\\\text{In Quadrant II, all other ratios are negative except}~ \sin \theta ~ \text{ and}~ \csc \theta.\\\\\text{Hence, the angle lies in the 2nd quadrant.}~$
