You're looking for a value z such that

\mathbb P(0

Because the distribution is symmetric, the value of z in either case will be the same.

Now, because the distribution is continuous, you have that

0.17=\mathbb P(0

The mean for the standard normal distribution is 0, and because the distribution is symmetric about its mean, it follows that \mathbb P(Z.

0.17=\mathbb P(Z

You can consult a z score table to find the corresponding score for this probability. It turns out to be z\approx0.4399.

Edward is driving a car on the highway. He drives for 28.5 miles in 3/8 of an hour. At this rate, how much distance can he cover
Rom4ik [11]

The distance covered in one hour is 76 miles.

<u>Step-by-step explanation:</u>

Edward drives a car for 28.5 miles.

Therefore, the distance he travels by the car = 28.5 miles.

The time it takes to drive 28.5 miles is 3/8 of an hour.

<u>The formula to find the rate :</u>

Rate = Distance traveled / Time taken in hours.

Here, the distance is 28.5 miles and time is 3/8 hour.

Rate = 28.5/ (3/8)

<u>To find the distance covered in 1 hour :</u>

Let us assume, 'x' be the distance covered in one hour.

Rate = x/1

<u>Now, comparing the rates to find the x value :</u>

⇒ 28.5 / (3/8) = x /1

⇒ x = 28.5 \times  8/3

⇒ x = 228/3

⇒ x = 76

Therefore, the distance covered in one hour is 76 miles.

Karolina [17]

Answer:

C

Step-by-step explanation:

Given that he has sold 40% then he still has to sell (100 - 40)% = 60%

60% of 70

= \frac{60}{100} × 70 = 0.6 × 70 = 42 → C

Nitella [24]
100% - 55.7%

= 100% - 55% - 0.70%

= 45% - 0.70%

= 44.30%

-----------

This means that the probability of selecting a female student at random is 44.3% as a percentage.
