Answer:

They have a zero in the ones place.

Step-by-step explanation:

The first one, A., is not always true.

10 * 3 = 30

This does have a a three in the ones place, but watch when we multiply it again.

10 * 30 = 300

Now, it's not true.

B. does not make sense because they would always be an ever number, an d never odd.

C does not make sense either, because they're never odd numbers.

This leaves D, to be the right answer.

Below is a probability distribution for the number of failures in an elementary statistics course. X 0 1 2 3 4 P(X=x) 0.41 0.18
faust18 [17]

Answer:

a) P(X=2)= 0.29

b) P(X<2)= 0.59

c) P(X≤2)= 0.88

d) P(X>2)= 0.12

e) P(X=1 or X=4)= 0.24

f) P(1≤X≤4)= 0.59

Step-by-step explanation:

a) P(X=2)= 1 - P(X=0) - P(X=1) - P(X=3) - P(X=4)= 1-0.41-0.18-0.06-0.06= 0.29

b) P(X<2)= P(X=0) + P(X=1)= 0.41 + 0.18 = 0.59

c) P(X≤2)= P(X=0) + P(X=1) + P(X=2)=0.41+0.18+0.29= 0.88

d) P(X>2)=P(X=3) + P(X=4)=0.06+0.06= 0.12

e) P(X=1 or X=4)=P(X=1 ∪ X=4) = P(X=1) + P(X=4)=0.18+0.06= 0.24

f) P(1≤X≤4)=P(X=1) + P(X=2) + P(X=3) + P(X=4)=0.18+0.29+0.06+0.06= 0.59

Jeremy and Brenda drove their cars in
harkovskaia [24]

Answer: Jeremy drove 84 miles.

Step-by-step explanation:

Let x represent the number of miles that Brenda drove.

If Jeremy drove twice

as far as Brenda, it means that the distance covered by Jeremy would be 2x miles

When they stopped after some time, they were already

126 miles apart. This means that the total distance covered by both of them is 126 miles. Therefore,

x + 2x = 126

3x = 126

x = 126/3

x = 42 miles

The number of miles that Jeremy drove is

42 × 2 = 84 miles

What is the simplified form?
yarga [219]

Answer:

\frac{6}{5x^{10}}

Step-by-step explanation:

Step 1: Simplify square roots

√72 = 6√2

√50 = 5√2

So, \frac{x^86\sqrt{2} }{x^{18}5\sqrt{2} }

Step 2: Cancel like terms

\frac{6}{x^{10}(5)}

Step 3: Rewrite

And we should get our answer!
