You have to isolate the a. Add fifteen to both sides of the equation, so it’s
2a=15-1
Then subtract 15 and 1, so then the quantity is 14
2a=14
Then divide 2 by both sides, and the answer is
a=7
Answer:
Formula for the SA (Surface Area) is 2πrh+2πr^2.
Replace the values and you get answer of 251.999570694 = 252pi
Answer:
addition property of equality
Step-by-step explanation:
Given the equation 4(x-5) = -12
Expand
4x - 20 = -12
Add 20 to both sides (addition property of equality)
4x-20+20 = -12+20
4x = 8
x = 8/4
x = 2
Hence the value of x is 2
The justification for step 2 is addition property of equality
Point-slope form is (y - y1) = m(x - x1) so just plug in your given info:
y - 2 = 3(x - 5)
so your answer is D!!
<span>a)
Z*_Upper = (76 - 62.7)/2.5 = 5.32
Z*_Lower = (57 - 62.7)/2.5 = -2.28
The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28).
Use normal distribution table to get the answer for p and multiply with 100 to get the percentage.
The other questions are now easy for you to answer on your own. Hope it helps.
