Answer:
Step-by-step explanation:
a. P(Z > 1.12) = 1-N(1.12) = 1-0.8686431=0.1313569
b. <em>P(Z S-2.35)</em> => P(Z <= 2.35) = 0.009386706
(please check interpretation of question b)
c. <em>POSZ s 1.34)</em> => P(0 <= Z <= 1.34) = 0.9098773 - 0.5 = 0.4098773
(please check interpretation of question c)
d. P(-0.8 sz s 2.44) => P(-0.8 <= 2.44) = 0.9926564 - 0.2118554 = 0.780801
(please check interpretation of question d)
Answer:
x = 9
Step-by-step explanation:
I think you wrote the question wrong (I am assuming that there is a x next to the -3).
Subtract 7
-27 = -3x
divide by -3
9 = x
-8 * 12 = -96....she gets $ 96 deducted every year for the DVD membership
You do
unit of measurement you are using (should be one for now): unit of measurement you want to convert it to.
next you put your measurement in the first one and make the second one your measurement multiplied by whatever your measurement is
Y = 1/2x + 2....the slope here is 1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(-2,4)....x = -2 and y = 4
now we sub and find b, the y int
4 = 1/2(-2) + b
4 = -1 + b
4 + 1 = b
5 = b
so ur parallel line is : y = 1/2x + 5
