A stack of cards is numbered 1 to 21. Leilani pulls one card from the stack. What is the best approximation for the probability that the card is a multiple of 5?

The approximation is 0.2( real value is 0.19)

Step-by-step explanation:

In this question, we are to calculate the best approximation if in a pack of cards labeled 1 to 21 , the card selected is a multiple of 5

First we know that the total number of options in our sample space is 21; from 1 to 21

now let’s get the multiples of 5. we have 5,10,15 and 20

The probability of selecting a multiple of 5 is thus; 4/21 . This can be approximately be said to be 0.2 ( actual value is 0.19)

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
