(7 × 10-5) × 0.0007

1 answer:

7 0

First we do what’s in the parentheses.
7 • 10 - 5 = 70 - 5 = 65
Then we do exponents. We don’t have any so we skip this step.
Then we do multiplication and division.
65 • 0.0007 = 0.0455
We don’t have any addition or subtraction so we skip this step.
The solution is 0.0455.

Please :’) help me out

expeople1 [14]

Answer:

10 units

Step-by-step explanation:

In this equation the parenthesis act as a multiplier, so you take w(2w + 2) = 40.

the variable w represents the number 1, so you multiply the numbers within the parenthesis.

w x 2w = 2w

w x 2 = 2w

so now you have 2w + 2w = 40

add the w's for 4w = 40

Now you need to get rid of the number next to the W.

divide the four from the W and divide the 40 as well

4w/4= w

40/4 = 10

W=10

The speed of cars passing through the intersection of Blossom Hill Road and the Almaden Expressway varies from 14 to 35 mph and

Ivan

Answer:

28.57% probability that the speed of a car is between 17 and 23 mph

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d is given by the following formula:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

14 to 35 mph and is uniformly distributed.

This means that $a = 14, b = 35$

What is the probability that the speed of a car is between 17 and 23 mph?

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

$P(17 \leq X \leq 23) = \frac{23 - 17}{35 - 14} = 0.2857$

28.57% probability that the speed of a car is between 17 and 23 mph
