The temperature dropped 2 °F every hour for 12 hours. What was the total number of degrees the temperature changed in the 12 hours?

24 degrees
14 degrees
-24 degrees
-2 degrees

Answers

Answer:

-24 degrees

Step-by-step explanation:

To find the total change in temperature, multiply 12 by -2, since it dropped 2 degrees each hour for 12 hours.

12*(-2)

= -24

This means -24°F was the total number of degrees the temperature dropped.

Answer:

The question mentions the keyword, "temperature drops" meaning we need to alternatively subtract.

[tex]t = -2 * 12[/tex]

If we know that positive 2 times 12 is 24, we know -2 times 12 will be negative 24°, because any negative number times a positive number is always a negative number.

FIRST CORRECT ANSWER GETS BRAINLIEST

Answers

The answer is 5s - 10t + 7
Following the order of operations (PEMDAS):

Step 1: simplify what’s inside the parentheses. Since we don’t know either variable s or t, we can’t simplify any further from what it already is.

Step 2: distribute the 5 to each of the terms inside the parentheses. This gets you (5s - 10t)

Step 3: arrange your final answer:
7 + 5s - 10t

You can’t simplify any more unless you know one the the variables so you are left with this.

Find the mean absolute deviation for the data set.

{3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6}

Answers

If the mean of the data set is 3.533. Then the mean absolute deviation for the data set will be 1.831.

How do find the mean absolute deviation of discrete data?

Suppose the data specified is of n sized as

[tex]\rm x_1, x_2, \cdots , x_n[/tex]

Let this data's mean will be μ

Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.

It is calculated as:

[tex]\rm M.A.D = \dfrac{\sum_{i=1}^n|x_i - \mu|}{n}[/tex]

The data set is given below.

3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6

Then the mean of the data will be

Mean = (3 + 5 + 6 + 3 + 2  + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6)/15

Mean = 53/15

Mean = 3.533

Then the mean absolute deviation for the data set will be

[tex]\rm M.A.D = \dfrac{|3-3.533| + |5-3.533| + |6 - 3.533| + |3 - 3.533| + ...+|6-3.533|}{15}[/tex]

M.A.D. = 27.4665/15

M.A.D. = 1.831111

A.
12

B.
10

C.
8

D.
15

Answers

Answer:

15

Step-by-step explanation:

60/4 which is the chance it gets out of being drawn

Using the concept of probability, the reasonable prediction for the number of times a purple marble will be drawn is 12 times (option A).

What is a reasonable prediction for the number of times a purple marble will be drawn?

To predict the number of times a purple marble will be drawn, we can use the concept of probability. The probability of drawing a purple marble in a single draw is the number of purple marbles (4) divided by the total number of marbles (5 + 6 + 3 + 2 + 4 = 20).

Probability of drawing a purple marble = 4 / 20 = 1/5

Since the student makes a total of 60 draws and each draw is independent (the marble is returned to the bag after each draw), we can use the concept of expected value to predict the number of times a purple marble will be drawn.

Expected value = Total number of draws × Probability of drawing a purple marble

Expected number of times a purple marble will be drawn = 60 × (1/5) = 12

What is the interquartile range of this data set?

{18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25}



Enter the answer in the box.

Answers

The interquartile range of the data set is 7.

Step-by-step explanation:

The given set of data is {18 , 17 , 10 , 25 , 20 , 20 , 30 , 18 , 18 , 30 , 25}

Arrange the data in ascending order:

10 , 17 , 18 , 18 , 18 , 20 , 20 , 25 , 25 , 30 , 30

Divide the data in two equal parts:

(10 , 17 , 18 , 18 , 18), 20 ,(20 , 25 , 25 , 30 , 30)

Divide each parenthesis in 2 equal parts:

(10 , 17), 18 ,(18 , 18), 20 ,(20 , 25), 25 ,(30 , 30)

Now we can say that,

Q₁ = 18 , Median = 20 , Q3 = 25

Interquartile rage of a data is :

I.Q.R. = Q3 - Q1

I.Q.R. = 25-18 = 7

Therefore the interquartile range of the data set is 7.
