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.
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: 8
Answer:

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

And replacing we got:

Now we can find the variance with the following formula:

And replacing we got:

And the standard deviation would be:

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:

And replacing we got:

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!
