what is a product of power?

Answers

Answer:

To find a power of a product, find the power of each factor and then multiply. In general, (ab)m=am⋅bm. am⋅bm=(ab)m. In other words, you can keep the exponent the same and multiply the bases.

Step-by-step explanation:

We use the power of a product rule when there are more than one variables being multiplied together and raised to a power. The power of a product rule tells us that we can simplify a power of a power by multiplying the exponents and keeping the same base.

Your teacher is selecting class partners by drawing names out of a bag. There are 12 girl's names and 10 boy's names. What is the probability that she selects a boy's name followed by a girl's name (without replacement)?

A) 20/77

B) 30/121

Answers

The answer would be A)20/77.
The reason is that without replacement it would go (10/22)*(12/21)=0.2597
You can do the easy route I did then do (20/77) which would also give you 0.2597.
The answer is exactly A there is not other choises make sense

HELP WITH EQUATION

Answers

I think  the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.

but l also think it could be 12 percent error.      

The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is  [tex]12 \%[/tex] .

What is percentage ?

A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".

Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]

We have,

Last trip to the hardware store [tex]=13.2[/tex] miles

Original trip to the hardware store [tex]=15[/tex] miles

So,

Using the above given formula;

Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]

                     [tex]=\frac{15-13.2}{15} *100[/tex]

                    [tex]=\frac{1.8}{15} *100[/tex]

                    [tex]=12 \%[/tex]

So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.

Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is    [tex]12 \%[/tex] .

I know what the equation for these problem is and what x is but what is < measures? Are these measures the same? I could have asked the teacher but what if she think that I am annoying.

Answers

Answer:

"x" is the actual value of x, <measures is the measures of the angles itselfs. so insert x into the expression to find the angle measure.

Step-by-step explanation:

Answer:

90 degree

Step-by-step explanation:

total angle is the sum of x-18 and x

since the figure is forming right angle so angle is 90 degree

90=x-18 +x

x=54

he measure of angle AFB = 78°

Answers

It’s angle AFE because its the one in the same line as AFB and since the line is 180 degrees that means they add up to 180
Angle AFE is supplementary to angle AFB because they are both along the line with points EFB. When two angles are along a straight line, they equal 180 degrees. This is also what the definition of supplementary is.
