Answer:
is greater than
Step-by-step explanation:
Mean: sum of numbers ÷ how many numbers there are
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.83333
Median: middle number
<u>3</u> <u>3</u> 4 5 <u>5</u> <u>9</u>
4 + 5 = 9
9 ÷ 2 = 4.5
4.83333 > 4.5 so the mean is greater than the median.
Hope that helps. :)
Answer:
x = 25
Step-by-step explanation:
Given
0.2(x + 5) + 1 = 7 ( subtract 1 from both sides )
0.2(x + 5) = 6 ( divide both sides by 0.2 )
x + 5 = 30 ( subtract 5 from both sides )
x = 25
Yes it is not because 40 thousand + 5 thousand = 90,000 which is close to her goal

Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.
Hope this helps :)
