Answer:
x is equal to 27
Step-by-step explanation:
To find this, start by making a proportion. In order to do so, you need to set it up using the smaller triangle on the right and the larger triangle on the left.
39/x = 65/(x + 18)
Now cross multiply to solve.
65*x = 39(x + 18)
65x = 39x + 702
26x = 702
x = 27
Answer:
False
Step-by-step explanation:
<u>Step 1: Check if 6 + 3 = 9</u>
<em>Yes, it is true</em>
<em />
<u>Step 2: Check if 5 * 5 = 20</u>
<em>No, it is false. 5 * 5 = 25</em>

Answer: False
Answer: x=8
Step-by-step explanation: Since we know that segment AB and BC are the same measure indicated by the black lines running perpendicular to the lines in triangle themselves, we know that angle A and angle C are the same measure. This means we know this equation... Solve this to complete step 1...
69°=(9y-3)°
If you solve for y, you should get 8. This means that y=8. In knowing that a triangle's interior angles add up to 180°, we know that Angle B must be... Solve this equation for step 2...
∠B=180°-(∠A+∠C)
If you solve to find angle B, you should get that ∠B=42°. Knowing this, we can set up another equation similar to that in step 1 (when we found y knowing the angle) to find x... Solve this equation for your third and final step...
42°=(5x+2)°
If done step 1 through 3 correctly, you should get x to be equal to... and the final answer... x=8
Answer:
Population: All undergraduates who attend a university and live in the United States
Step-by-step explanation:
We are given the following situation in the question:
"A polling organization contacts 1835 undergraduates who attend a university and live in the United States and asks whether or not they had spent more than nbsp $200 on food nbsp in the last month."
For the given situation, we have
Sample size, n = 1835
Sample: 1835 undergraduates who attend a university and live in the United States
Variable: whether or not they had spent more than $200 on food in the last month
Thus, the population for this scenario will be
Population: All undergraduates who attend a university and live in the United States
