45.7 kilometers =<br> meters
VashaNatasha [74]

Answer:

45.7 kilometers = 45,700 meters

Explanation:

Hi!
Okay, so basically, in one kilometer, there are 1000 meters.
Using this problem, all you have to do is <u>multiply 45.7 by 1000</u>, which is 45,700.

Whatever value is used for kilometers (ex. 2), just multiply by 1000, and you’ll get the value as meters (ex. 2 x 1000 = 2000 meters).


Hope this helps!

If f(x) = 2x^3 - 3x + 1 find f(3)
madreJ [45]
Okay so what f(3) is saying is that x=3. You have to plug three in for x to make the new equation of 2(3)^3-3(3)+1 next you would do pemdas which is parethesis then exponets then multiplication/division then addition/subtraction to get 2*3=6 6^3 is 216 216-3*3 is 207 207+1 is 208 so the answer is f(3)=208

Suppose that the handedness of the last fifteen U.S. presidents is as follows:
ladessa [460]

Answer:

(C) No, since 0.47 is not equal to 0.13.

Step-by-step explanation:

We have two events, A and B.

I am going to say that P(A) is the probability that a president is left-handed.

I am going to say that P(B) is the probability that a president is a Democrat.

P(B/A) is the probability that the probability that the president is a Democrat, given that he is left-handed.

If P(B/A) = P(A), then the events are independent.

In this problem, we have that P(B/A) = 0.13 and P(A) = 0.47. So, "being left-handed" is not independent of "being a Democrat" and the correct answer is

(C) No, since 0.47 is not equal to 0.13.
