4f(2)=4×5/2=10
g(10)=10×(10+1)²=1210
so the answer is d.
your description is different from the picture. what i answered was the question in the picture.
Answer:
5901
Step-by-step explanation:
The margin of error is the critical value times the standard error.
ME = CV × SE
For α = 0.05, the critical value is z = 1.96.
The standard error of a proportion is √(pq/n). Given p = 0.04, then q = 1−p = 0.96.
The margin of error is 0.5% or 0.005.
Plugging in:
0.005 = 1.96 √(0.04 × 0.96 / n)
n ≈ 5901
Answer:
m∠ABE = 129 degrees
Step-by-step explanation:
360 degrees = max/total degrees in a circle
Given angles = 65 degrees & 37 degrees
Unknown/congruent angles = m∠ABE & m∠DBC
••••••••••••••••••••••••••••••••••••••••••
That was just information for the shape!
Now let’s get into the question.
Question: Find the measurement of m∠ABE
65 + 37 + m∠ABE + m∠DBC = 360 degrees
Add 65 and 37
102 + m∠ABE + m∠DBC = 360 degrees
Subtract 102 from 360 degrees
m∠ABE + m∠DBC = 258 degrees
Divide 258 in half
m∠ABE & m∠DBC = 129 degrees
—————————————————
Therefore m∠ABE = 129 degrees
Corey got scammed and should return that paint
Answer:
area of rectangle = 120 cm²
area of triangle = 24 cm²
area of trapezoid = 144 cm²
Step-by-step explanation:
12 * 10 = 120
12 * 4 = 48
48 / 2
add the triangle and rectangle area together
