Simply what you do is times 80 by 10 so 80x10=800. and then, you times 2 by 2 so 2x2 = 4. next you add them together so the answer would be 804 :)

In a certain constituency, there are 8 500 voters and

babymother [125]

First let's find how much is 15% of 8500 voters.

To do that, we can multiply 15 by 8500 and then divide by 100.

Work: 15 x 8500 = 127500

127500/100 = 1275

Therefore 15 percent of 8500 is 1275.

Then, we subtract 1275 from 8500 to find the amount of people who did vote.

8500 - 1275 = 7,225

Thus, 7,225 people voted while 1,275 people did not.

If three quarters of a number decreased by twenty is equal to eighty two, what is that number?

Studentka2010 [4]

A number is :

$x$

_________________________________

Three quarters of it means :

$\frac{3}{4}x \\$

_________________________________

Decrease by 20 means :

$\frac{3}{4}x - 20 \\$

_________________________________

Equals to 82 means :

$\frac{3}{4}x - 20 = 82 \\$

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

$\frac{3}{4}x - 20 = 82 \\$

Plus sides 20

$\frac{3}{4}x = 82 + 20 \\$

$\frac{3}{4}x = 102 \\$

Multiply sides by 4

$3x = 102 \times 4$

Divided sides by 3

$x = \frac{102 \times 4}{3} \\$

$x = \frac{102}{3} \times 4 \\$

Simplify

$x = 34 \times 4$

$x = 136$

So that number is 136 .

And we're done.

Thanks for watching buddy good luck.

Construct the discrete probability distribution for the random variable described. Express the probabilities as simplified fract

lisov135 [29]

Answer:

$P(X = 0) = 0.03125$

$P(X = 1) = 0.15625$

$P(X = 2) = 0.3125$

$P(X = 3) = 0.3125$

$P(X = 4) = 0.15625$

$P(X = 5) = 0.03125$

Step-by-step explanation:

For each toss, there are only two possible outcomes. Either it is tails, or it is not. The probability of a toss resulting in tails is independent of any other toss, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
