If one angle of a triangle is 90°, then the other two add to 90°. Write the To Prove statement

hram777 [196]

So a triangle is always 180°.
If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be.
180°-90°=90°
So the other two angles added together will have to equal 90°.

Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 20. What is the

qaws [65]

Answer:

The minimum score needed to be in the top 2% of the scores on the test

is n = 10,00,000

Step-by-step explanation:

Step(i):-

Mean of the Population = 110

Standard deviation of the Population = 20

The estimated error = 2% = 0.02

Step(ii):-

The estimated error is determined by

$E = \frac{S.D}{\sqrt{n} }$

$0.02 = \frac{20}{\sqrt{n} }$

⇒ $\sqrt{n} = \frac{20}{0.02} = 1000$

Squaring on both sides, we get

n = 10,00,000

The minimum score needed to be in the top 2% of the scores on the test

is n = 10,00,000

What number am I? If you divide me by 8, the quotient is 3.

bonufazy [111]

Answer:

Step-by-step explanation:

Let the number we are looking for = $x$ .

∴ According to the question:

$x$ ÷ 8 = 3

• Multiply both sides by 8:
$x$ = 8 x 3

$x$ = 24
