Given that,

→ 5 : 20 :: x : 100

Then we have to,

find the second number to 100.

→ 100/20

→ 5

Now multiply each term by 5 in 5:20,

→ 5 × 5 : 20 × 5

→ 25 : 100

→ x = 25

Now these ratio will be,

→ 5 : 20 :: <u>2</u><u>5</u> : 100

Hence, the value of x is 25.

Answer:

25

Step-by-step explanation:

5:20  

We want to get the second number to 100

100/20 = 5

Multiply each term by 5

5*5 : 20*5

25 : 100

x is 25

A line has a slope of 3/7 and a y-intercept of 0. What is it’s equation in slope-intercept form?
Ilia_Sergeevich [38]

Answer:

y = 3/7x

Step-by-step explanation:

Well slope-intercept form means this -----> y=mx+b

m = slope

b = y- intercept

In the question given they already telling us the slope (3/7) and the y intercept (0) so to put it into slope intercept form it will be ---> y= 3/7x

* If your y - intercept is zero you don't need to replace it with the b because its zero it means nothing (it has no value)

Hope this helps!!!

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minute
fredd [130]

Answer:

0.0322; 0.9929

Step-by-step explanation:

Since the data is normally distributed, we use z scores for these probabilities.

The formula for a z score of a sample mean is

z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}

For the sample of mildly obese people, the mean, μ, is 371; the standard deviation, σ, is 65; and the sample size, n, is 6.

Using 420 for X,

z = (420-371)/(65÷√6) = 49/(65÷2.4495) = 49/26.5360 ≈ 1.85

Using a z table, we see that the area under the curve to the left of this is 0.9678.  However, we want the area to the right, so we subtract from 1:

1-0.9678 = 0.0322

For the sample of lean people, the mean, μ, is 528; the standard deviation, σ, is 108; the sample size, n, is 6.

Using 420 for X, we have

z = (420-528)/(108÷√6) = -108/(108÷2.4495) = -108/44.0906 ≈ -2.45

Using a z table, we see that the area under the curve to the left of this is 0.0071.  We want the area under the curve to the right, so we subtract from 1:

1-0.0071 = 0.9929

As part of their fundraising for Right To Play, the student council is having a fun-fair at lunch in the school yard. You will b
Lubov Fominskaja [6]

Step-by-step explanation:

I used a co-ordinate graph and place the ticket booth at the origin then I chose difference of four but you can choose any and place three events equidistant from the origin by using the X- and Y- axis to easily determined a distance of 4 from the origin .

(0-4, 0) =( 4,0)

(0+4, 0) = (4 ,0)

(0, 0+4) = (0, 4)

if the both are placed first u would need to find the equation of a circle that contains all three points and place the booth at centre

you do this by creating the system of 3 equations inputting the x,y coordinates of each booth and solving for h,k,r

equation of a circle (X-H) 2 +( Y-K) 2 = r2

Hope It helps
