Answer:

5 days

Step-by-step explanation:

If you write it out it will look like this 8 1/2÷1 7/10

since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2 1 7/10 -> 17/10

So it looks like 17/2÷17/10

because of maths you have to turn 17/10 into 10/17

And when you do the maths (multiply it together) you get 5

Answer:

5 days

Step-by-step explanation

1.turn 8 1/2 back to its original form which is 17/2

2. multiply by 5 because 2 times 5 is 10 which is the number we need the make the denominators even and because we multiplied by 5 on the bottom we multipliy by 5 on the top to make it even which is 85/10

3. put 1 7/10 back to its original form which is 17/10, and because 85 divided by 17 is 5 your answer would be 5 days

How to do this problem

Mumz [18]

Answer:

y = 3/2x -14

Step-by-step explanation:

do the inverse of -2/3 what is 3/2

and now sole the equation of y+8 = 3/2(x-4)

distribute 3/2 ---> y+8 = 3/2x - 8

subtract 8 from both sided getting you y=3/2x-14

Answer:

The probability that the maximum speed is at most 49 km/h is 0.8340.

Step-by-step explanation:

Let the random variable X be defined as the maximum speed of a moped.

The random variable X is Normally distributed with mean, μ = 46.8 km/h and standard deviation, σ = 1.75 km/h.

To compute the probability of a Normally distributed random variable we first need to convert the raw score of the random variable to a standardized or z-score.

The formula to convert X into z-score is:

$z=\frac{X-\mu}{\sigma}$

Compute the probability that the maximum speed is at most 49 km/h as follows:

Apply continuity correction:

P (X ≤ 49) = P (X < 49 - 0.50)

= P (X < 48.50)

$=P(\frac{X-\mu}{\sigma}$

*Use a z-table for the probability.

Thus, the probability that the maximum speed is at most 49 km/h is 0.8340.
