Answer: -5/4

Step-by-step explanation:

Step-by-step explanation:. The first says “I know that 10 is one-tenth of 100. I will therefore divide 50 by 10. The answer is 5”.

This is fine when the numbers are relatively simple. But suppose the numbers are more complicated.

What is 22% of 46?

Now it’s much less straightforward. You can’t just work out what 22% is, expressed as a fraction, and anyway, it’s not a simple fraction.

Instead, you have to divide 46 into 100 equal parts, and work out what 22 of them would be when added together.

So: 46 ÷ 100 = 0.46 [remember, when you divide by 100, you move the decimal point two places to the left].

0.46 × 22 = 10.12

Answer: 22% of 46 is 10.12.

Approximately 95% of data falls within 2 standard deviations (±2) of the mean. Option D is correct.

A normal distribution is a type of continuous probability distribution for a real-valued random variable such that the values are symmetric about a mean and the curve has bell shape.

Standard deviation is the measure of the randomness of the distribution. The curve has its peak at the mean.

As standard deviation increases, the peak of the curve comes lower and the distribution becomes more and more dispersed.

In a normal distribution 68% of the values falls within 1 standard deviation

and 95% of the values falls within two standard deviations. 99% of the values falls within three standard deviations.

Hence, approximately 95% of data falls within 2 standard deviations (±2) of the mean.

Step-by-step explanation:

Answer:

3x and 8x are like terms.

Step-by-step explanation:

Like terms are the terms that share the same variables. They do not have to share the same coefficients - or, in other words - the numbers in front of the variable do not have to be the same. Only the variable has to match.

So, looking at the expression, the only two terms that have the same variable are 8x and 3x, which both have the variable x. Therefore, 3x and 8x are like terms.

Answer:

8(2×+7y)

Step-by-step explanation:

8 is the largest factor

Answer:

x = 1

y = 2

Step-by-step explanation:

x=1 and y=2.

step 1 ,

2^2x*3^y=36

3^y= 36/2^2x ———- equal 1

step 2,

put the value of 3^y in 2^x*3^y = 18 (equal 1)

WHEN BASES ARE SAME POWERS ARE SUBTRACTED IN CASE OF DIVISION.

Therefore, 2^x-2^2x= 1/2

2^-x= 1/2

(1/2)^x = 1/2

COMPARING THE POWERS BECAUSE THE BASE IS SAME.

x=1.

Now, putting the value of x=1 in 2^x*3^y = 18

y=2.

Answer:

-16

Step-by-step explanation:

The question asks to find x from 2(4)x if x = -2

All that we have to do is substitute to get our answer :

f(-2) for (x) = 2(4)x

f(-2) = 2(4)(-2)

f(-2) = 2(-8)

f(-2) = -16

Therefore, x = -16

Answer:

-16

Step-by-step explanation:

Plug in -2 for x and then multiply 2 and 4 to get 8 (-2) which is then -16. Hope that helps!

Answer:

vertex angle = 180° - 2x

Step-by-step explanation:

Since, the measure of each base angle of an isosceles triangle is represented by x.

So, by interior angle sum postulate of a triangle, we have:

x + x + vertex angle = 180°

2x + vertex angle = 180°

vertex angle = 180° - 2x

So, the vertex angle is represented by (180° - 2x).

Answer:

$25.50

Step-by-step explanation:

So we have a 15% off coupon. We can multiply 25×.85 to find our new price.

Our total is now $21.25

Now to find the tip do $21.25 +(.2 × 21.25)

*The .2 is 20 percent of our discount price.*

We then get $25.50

Answer:

If your good at math plz help me

i think this is the answer, hope A(-3)=n-5

==================================================

Work Shown:

[tex]a_1 = -3 = \text{ first term}\\\\d = -5 = \text{ common difference}\\\\a_n = a_1 + d(n-1) = \text{ nth term}\\\\a_n = -3 + (-5)(n-1)\\\\a_n = -3 -5n + 5\\\\a_n = -5n + 2\\\\[/tex]

The common difference is due to us adding -5 to each term to get the next one. Example: -3+(-5) = -8, or -8+(-5) = -13.

--------------------

As a way to check if we have the correct nth term formula, plug in values of n to see if we get the correct sequence value

For instance, if n = 1, then

[tex]a_n = -5n+2\\\\a_1 = -5(1)+2\\\\a_1 = -5+2\\\\a_1 = -3\\\\[/tex]

Which matches with the first term given to us.

Or if n = 2, then,

[tex]a_n = -5n+2\\\\a_2 = -5(2)+2\\\\a_2 = -10+2\\\\a_2 = -8\\\\[/tex]

That matches the second term given to us. I'll let you check the others.
