Answer:
y = 27
Step-by-step explanation:
The given are two similar triangles.
We can use the following equation to find the variables:
Cross multiply fractions
32*18 = 24(y-3)
576 = 24y - 72
add 72 to both sides
648 = 24y
divide both sides by 24
27 = y
Given:
m∠CXD = 30°
m∠DXE = 30°
To find:
The measure of angle CXE.
Solution:
The measure of angle CXE is sum of the measures of angle CXD and DXE.
⇒ m∠CXE = m∠CXD + m∠DXE
⇒ m∠CXE = 30° + 30°
⇒ m∠CXE = 60°
The measure of angle CXE is 60°.
I would say B.
Your starting term is 10, so that is your a1 value. Each time you add 4 to the number before, like 10+4=14 and so on, so that would mean (a-1)+4.
V=hpir²
1/2 full
Vcylinderthisone=(1/2)hpir^2
given
h=250
r=100
so
V=(1/2)(250)pi(100)²
V=125pi10000
V=1250000pi
aprox pi=3.141592
V=3926990 cm^3
divide by 1000
3926.99 liters
about 3927 liters
Z-test should be used when the parent standard deviation is known and the sample size is greater than or equal to 30 (to satisfy the Central Limit Theorem). A T-test should be used when these two rules do not apply.
