ASAP! The graph shows outdoor temperatures (F) recorded one fall evening in Ohio. At what rate did the temperature change during

babymother [125]

Your answer would be D) -3°F/hour
Look at it this way...

47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm

The temperature is going down by 1°F every 20 minutes so...

-1°F/20 minutes

Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...

So an hour is 60 minutes and 60/20 = 3

So if you do 3・-1

You get the answer... -3°F/hour

If one angle is 8 less than four times th of its complementary angle find both angle

charle [14.2K]

Answer:

Let the angle be x

∘

. Then it's complement = (4x)

∘

We know that if the sum of two angles is equal to 90

∘

then the angles are said to be complementary.

Step-by-step explanation:

4x+x=90°

5x=90°

x=90°/5

x=18

4×18=72°

This is the complete solution!

20 points help w part b

Hatshy [7]

Answer:

8:07 am

Step-by-step explanation:

It takes 9 minutes to walk from his house to the bus station. It then takes 92 minutes for the bus to travel from Birmingham to Coventry. After arriving, he takes 12 minutes to reach his workplace. This takes a total of 113 minutes.

9 + 92 + 12 = 113

Convert 113 minutes to hours and minutes.

113 - 60 = 53

1 hr and 53 min

He has to be at work by 10. Subtract the time it takes to get to his work by the time he has to get there.

10 - 1 hr = 9

9 - 53 min = 8:07

The latest time he can leave is 8:07.

The amount of time it takes Ariana to do a math problem is continuous and uniformly distributed between 38 seconds and 79 second

solniwko [45]

Answer:

29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem

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, d being greater than c, is given by the following formula:

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

Uniformly distributed between 38 seconds and 79 seconds.

This means that $a = 38, b = 79$

What is the probability that it takes Ariana between 58 and 70 seconds to do a math problem

$c = 58, d = 70$

$P(58 \leq X \leq 70) = \frac{70 - 58}{79 - 38} = 0.2927$

29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem
