Answer:

The answer should be 10,000.

Step-by-step explanation:

Tia went home and said to her mom,"I learned that 10 to the power of 4 is the same as 40,000."

10 to the power of 4 means 10^{4} that is simplified as 10\times10\times10\times10 or 10,000.

10 to the power of 4 means 4 zeroes after 1 , and not after 4.

10 to the power of 4 is basically saying 10 x 10 x 10 x 10. This would equal ten thousand. Even though you are using the exponent 4 to do 10 to the fourth power, you're not going to have a 4 in the ten thousands place.

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is
Maksim231197 [3]
X + y = 24....multiply by -3
3x + 5y = 100
---------------
-3x - 3y = - 72 (result of multiplying by -3)
3x + 5y = 100
--------------add
2y = 28
y = 28/2
y = 14

x + y = 24
x + 14 = 24
x = 24 - 14
x = 10

solution is (10,14)...and x represents 3 point q's and y represents 5 point q's......so this tells me there are 10 three point q's and 14 five point q's.

If f(x)=7(x−1)+8 , what is the value of f(1) ?
AnnyKZ [126]

Answer:

8

Step-by-step explanation:

Evaluate 7 (x - 1) + 8 where x = 1:

7 (x - 1) + 8 = 7 (1 - 1) + 8

1 - 1 = 0:

7×0 + 8

0×7 = 0:

0 + 8

0 + 8 = 8:

Answer:

Range = 60-5=55

In order to find the variance and deviation we need to find the mean with this formula:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X =36.07

Now we can find the variance with the following formula:

s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}

And replacing we got:

s^2=357.610

And the standard deviation would be:

s = \sqrt{357.610}= 18.911

For this case since the range observed is large is better to use a measure of variation in order to check the spread of the values and take a decision useful

Step-by-step explanation:

For this case we have the following dataset:

60 58 55 53 47 45 44 43 25 25 20 18 7 5

We can find the range with this formula:

Range = Max-Min

And replacing we got:

Range = 60-5=55

In order to find the variance and deviation we need to find the mean with this formula:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X =36.07

Now we can find the variance with the following formula:

s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}

An eagle leaves its nest and flies 5 miles east. Then the eagle flies 3 miles north. To the nearest tenth, how far is the eagle
kati45 [8]

Hello!

It appears that this is creating a triangle. It gives us leg lengths of 3 and 5. If we assume that this is a right triangle, we can use the Pythagorean Theorem. We add up the square of each of our numbers. Then we find the square root of our answer. Basically, a²+b²=c².

25+9=34

√34≈5.83

Therefore, the eagle is about 5.83 miles from its nest.

I hope this helps!
