A)each foot equals 12 inches
B)12x
C)252=12x divide each side by 12 then x=21
7)2.54x multiply by 12 and then the answer is 30.48
Answer:
p(z<0.42) = 0.6628
Step-by-step explanation:
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:
μ = 0
σ² = 1
Using a calculator, we find that:
p(z<0.42) = 0.6628 (See picture attached)
Answer:
EF=6
Step-by-step explanation:
E is the midpoint, so DE = EF
DE = 15-3x
EF = x+ 3
Since DE = EF,
15 - 3x = x + 3
-4x = -12
x = 3
If x = 3,
DE = 15 - 3*3, 15 - 9 = 6
EF = x+ 3, so EF = 3 + 3 = 6
Real distance of Earth from Sun . . . 93 million miles
= 1 AU (Astronomical Unit)
10 times farther . . . . . 930 million miles = 10 AU
Compare:
==> Saturn . . . 9.5 AU
==> Uranus. . 19.2 AU
If Earth were 10 times farther from the sun than we really are,
then our planet would be just barely past Saturn ... about 10%
of the way from Saturn to Uranus.
