Let's present a solution for the generic case.
The equation will be of the form y=ax+b

If (7,3) is on it, then 3=7a+b
If (14,6) is on it, then 6=14a+b

Now we have a system we can solve.

3=7a+b => b = 3-7a
6=14a + 3-7a => 3 = 7a => a=3/7

b  = 3-7*3/7 = 0

So y = (3/7)x is the equation.

If an hourglass takes an average of 1 hour to empty a full cycle, what probability of time does it take longer than 72 minutes i
Arturiano [62]

Answer:

0.82%

Step-by-step explanation:

First find the z-score.

z = (x − μ) / σ

z = (72 − 60) / 5

z = 2.4

Use a chart or calculator to find the probability.

P(Z > 2.4) = 1 − P(Z < 2.4)

P(Z > 2.4) = 1 − 0.9918

P(Z > 2.4) = 0.0082

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.
