Answer:

$360 : $600

Step-by-step explanation:

If I'm understanding the problem right, you're looking for this to be put into a 3:5 ratio.

When doing problems like these, I'll add the two numbers in the ratio together, then divide the number (in this case 960) by the sum of the ratios, which in this case is 8.

From there you'd divide 960/8, which is 120. Based on that, you can assume 120 is equal to "1" in the ratio. Then multiply the base unit 1 by each one of the ratios.

120 x 3 = 360

120 x 5 = 600

The ratio will look like this: 360:600

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.

What is the equation of a line with a slope of −4−4 and a point (−2,5)

Darya [45]

Here, we can formulate the slope-intercept equation from the point and the slope:

Slope = -4/-4 = 1
x1 = -2
y1 = 5

By point-slope form:

(y-y1) = m (x - x1)
(y-5) = 1(x +2)

y-5 = x +2

Simplifying to slope-intercept form:

y = x + 7

Therefore, the slope-intercept form would be y = x+7

I hope my answer has come to your help. God bless and have a nice day ahead!

How can I divide thirty-three into two groups so the ratio is four to seven?

lana [24]

Look at it this way:

-- Since the two groups have the ratio of 4 to 7, then the first group has 4 parts
and the other group has 7 parts.

-- If the first group has 4 parts and the other group has 7 parts, then they have
11 parts all together.

-- Those 11 parts are all parts of 33. There must be ( 33 / 11 ) = 3 items in each part.

Now you can go back to the groups . . .

-- The first group has 4 parts.
With 3 items in each part, that's (4 x 3) = 12 items.

-- The other group has 7 parts.
With 3 items in each part, that's (7 x 3) = 21 items.
