Scorpion4ik [409]3 years ago

Assume that this number is n.
Difference between two number means the subtraction between them.
Therefore, "<span>The difference between a number and 12 is 20" means that when subtracting these two numbers, the result is 20.

Since the question did not mention which number is greater, therefore, we have two ways to write the equation. 
These two ways are as follows:
x - 12 = 20, and
12 - x = 20

Find x.______________a0
velikii [3]

Answer:

x=4

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

\frac{2}{y}=\frac{y}{6}

y^2=12

y=\sqrt{12}

y=2\sqrt{3}

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

a^2+b^2=c^2

2^2+(2\sqrt{3})^2=c^2

4+12=c^2

c^2=16

c=4

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

x=4

solve the average time for a student to complete this quiz is 24 24 minutes with a standard deviation of 2 minutes. What is the
LuckyWell [14K]

Answer:

The correct answer is "(18, 30) minutes".

Step-by-step explanation:

Mean,

= 24

Standard deviation,

= 2

The range of minutes where 99.7% of individuals completed the quiz will be:

= Mean \pm 3\times Stdev

On substituting the values, we get

= 24 \pm 3\times 2

= 24 \pm 6

now,

= 24-6

= 18

Or,

= 24+6

= 30

i.e., 18 to 30 minutes
