Of in mathematics means multiplication

80% = 80/100 = 0.8

$0.8 \times 400 = \boxed{320}$

80% of 400 is 320.

80% of 400

We can set up a proportion because it makes things more clear.

First, we need to assume that 400 is our '100'. Usually, 100 is our total value.

400/x=100/80
<span>(400/x)*x=(100/80)*x </span>
<span>400=1.25x </span>
<span>400/1.25=x </span>
<span>320=x </span>
<span>x=320
</span>
Our final answer: 320

Suppose someone tells you that she has a triangle with sides having lengths 3.5, 4.5 and 5.5 yards. Is this a right triangle?

Katarina [22]

You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.

But, 3.5^2 + 4.5^2 is not equal to 5.5^2.

xxTIMURxx [149]

Answer:

Point estimate for the population variance = 3.92 * $10^{-3}$ .

Step-by-step explanation:

We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;

X X - $Xbar$ $(X-Xbar)^{2}$

1.13 1.13 - 1.188 = -0.058 3.364 * $10^{-3}$

1.15 1.15 - 1.188 = -0.038 1.444 * $10^{-3}$

1.15 1.15 - 1.188 = -0.038 1.444 * $10^{-3}$

1.24 1.24 - 1.188 = 0.052 2.704 * $10^{-3}$

1.27 1.27 - 1.188 = 0.082 <u> 6.724 * </u> $10^{-3}$ <u> </u>

$\sum (X-Xbar)^{2}$ <u>= 0.01568 </u>

Firstly, Mean of above data, $Xbar$ = $\frac{\sum X}{n}$ = $\frac{1.15+1.24+1.15+1.27+1.13}{5}$ = 1.188

Point estimate of Population Variance = Sample variance

= $\frac{\sum (X-Xbar)^{2}}{n-1}$ = $\frac{0.01568}{4}$ = 3.92 * $10^{-3}$ .

Therefore, point estimate for the population variance = 3.92 * $10^{-3}$ .

WHAT ARE PARTIAL PRODUCTS FOR 543*18

andreyandreev [35.5K]

Answer:

5, 48, 4, 32, 3, 24

Step-by-step explanation:

do not get intimidated by this question , its very easy

let's break it ike this, 543 x 18

get the bigger number first , 543

each digit will be multiply by the opposite number which it's 18

READY? watch! 543 ( we'll separate them)

1. 5x (18) we'll break the 18 watch. 1 and 8 and we'll multiply each by 5

<u>5</u>x1= 5

5x8= 48.

2. 4x 18

<u>4</u>x1=4

4x8=32

3. <u>3</u>x 18

3x1=3

3x8= 24
