Pretty sure it’s B
i added and subtracted the numbers to find out that the ratio between the numbers on B are correct
Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
The volume of the cylinder is 4710 cubic inches
Step-by-step explanation:
Volume of the cone = 1570 cubic inches
Volume of cone = 1/3(volume of the cylinder)
So,
Volume of the cylinder = 3(volume of the cone)
Volume of the cylinder = 3(1570)
= 4710 cubic inches
The volume of the cylinder is 4710 cubic inches
The value of the text statistic. F is given as : 0.742 See explanation below.
<h3>What is a test statistic?</h3>
A test statistic is a numerical value determined by a statistical test.
It quantifies the distance between your observed data and the null hypothesis of no link between variables or no difference between sample groups.
<h3>What is the solution to the answer above?</h3>
Test Statistic F is given by:
= σ²₁/σ²₂
= 0.93²/1.08²
= (0.93/1.08)²
= 0.8611²
= 0.742

Answer:
f(x) = -2 (x + 2)² - 4
Step-by-step explanation:
f(x) = a (x - h)² + k (h , k) is vertex h = -2 k = -4
pass point (-1 , -6) f(x) = -6 and x = -1
-6 = a (-1 - (-2))² + (-4)
-6 = a - 4
a = -2
quadratic function: f(x) = -2 (x + 2)² - 4
