Answer
1.1 * 10^4 = 11,000
2.1 * 10^3 = 2,100
The elephant weighs 9,000 more lb than the giraffe
A
Answer:
.
Step-by-step explanation:
We have 5 ft 9 in = 69 in, so
P(X > 69) = P((X - 64.1)/2.5 > (69 - 64.1)/2.5) = P(Z > 1.96)
where X and Z both represent women's heights, but Z is normally distributed with mean 0 and s.d. 1.
Then consulting a table of z-scores, you'll find that P(Z > 1.96) ≈ 0.025. So approximately 2.5% of women are taker than 5'9''.

Step-by-step explanation:
Let
x------> Karla's car mileage
1) First way
we know that
100%-35%=65%=65/100=0.65
so
x=0.65(60 miles/gallon)=39 miles/gallon
2) Second way
by proportion
Answer:
True
False
True
Step-by-step explanation:
Interior angles are supplementary
Corresponding angles makes mangle2 and mangle6 the same deg
mangle1 = mangle5 (corresponding angles)
mangle5 = mangle8 (vertically opposite angles)
