Answer:
-5c³d-⁴
Step-by-step explanation:
15÷3=5
for c and d we subtract powers that
First, to find out the number of students who scored below Amanda, we must find the z-score value of Amanda's score using the formula below.

where Z is the z-score, Χ is the expected average value, μ is the mean of Χ, and δ is the standard deviation. Thus, we have


Thus, using the z-table, we have P(Z<0.90) = 0.8159. Since we have wanted to find the number of students who scored below Amanda, then from the whole, we have (1 - 0.8159) = 0.1841. That means, out of 1000 students, 0.1841 of them scored below Amanda. Thus, we have (0.184)(1000) = 184.
Answer: 184 students
I think it’s positive two
Answer:
y = 3x - 6
Step-by-step explanation:
Find the slope of the line:
3 - 6 / 3 - 4 -> -3/-1 so the slope is 3
Now use the point-slope form to find the slope-intercept form:
y - 3 = 3 (x - 3)
y - 3 = 3x - 9 add three to each side...
y = 3x - 6
Answer:
3 units
Step-by-step explanation:
The formula for the volume of the cone is given by


Substituting in above formula
![18\pi=\frac{1}{3} \pi*x^{2}*2x\\ \\ 54=2x^{3} \\ \\ x^{3} =27\\ \\ x=\sqrt[3]{27} \\ \\ x=3\ units](https://tex.z-dn.net/?f=18%5Cpi%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%2Ax%5E%7B2%7D%2A2x%5C%5C%20%5C%5C%2054%3D2x%5E%7B3%7D%20%5C%5C%20%5C%5C%20x%5E%7B3%7D%20%3D27%5C%5C%20%5C%5C%20x%3D%5Csqrt%5B3%5D%7B27%7D%20%5C%5C%20%5C%5C%20x%3D3%5C%20units)
Thus, the radius of the cone is 3 units.
