I Need Help With These I Forgot How To Solve Them

Answer 1

Step-by-step explanation:

if x = 7 and y = 4

a) x + 2y

= 7 + 2 . 4

= 7 + 8

= 15

b) (2x - y)/5

= (2 . 7 - 4)/5

= (14 - 4)/5

= 10/5

= 2

#CMIIW

Answer 2

Answer:

The first equation is 15 and the second equation is 2.

Step-by-step explanation:

You have to use substitution. For the first equation it would be: 7 + 2(4),which is 7 + 8,which is 15. For the second equation it would be: 2(7) - 4 divided by 5,which is also 14 - 4 divided by 5,which is 10/5, which is 2.

Over winter break, Alex took a trip to Montana and recorded the temperatures for the week. The temperature for the first six days of his trip are listed below. If the average temperature for the week he was on vacation was 1.2 degrees Fahrenheit, what was the temperature for Sunday?


Monday -5.3F
Tuesday 3.6F
Wednesday 6.7F
Thursday 0F
Friday 10F
Saturday -4.3F
Sunday ?F

Answers

Answer:

The temperature for Sunday was -2.3F

Step-by-step explanation:

When we have a set of N values:

{x₁, x₂, ..., xₙ}

The mean is given by:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

In this case, we have the set:

{-5.3F, 3.6F, 6.7F, 0F, 10F, -4.3F, X}

Where X is Sunday's temperature.

So we have a set of 7 values, and we know that the mean of this set is 1.2F

Then we have the equation:

[tex]1.2F = \frac{-5.3F + 3.6F + 6.7F + 0F + 10F - 4.3F + X}{7}[/tex]

If we multiply both sides by 7, we get:

[tex]1.2F*7 = 8.4F =-5.3F + 3.6F + 6.7F + 0F + 10F - 4.3F + X[/tex]

Now we can just solve this for X

8.4F + 5.3F - 3.6F - 6.7F - 10F + 4.3F = X

-2.3F = X

The temperature for Sunday was -2.3F

-3x -5 = 16

Answers

Answer:

x = -7

Step-by-step explanation:

-3x -5 = 16

step 1 add 5 to each side

-5 + 5 cancels out

16 + 5 = 21

we now have -3x = 21

step 2 divide both sides by -3

-3x / -3 = x

21 / - 3 = -7

we're left with x = -7

Answer:

x = -7

Step-by-step explanation:

-3x -5 = 16

     +5   +5

-3x = 21

-3x/-3 = 21/-3

x = -7

Answers

Answer:

Step-by-step explanation:

44/40

How many times can 40 fit evenly into 44? 1

So 44 - 40 (the 1) = 4

There are 4 remaining which will be the numerator.

The denominator stays the same: 40.

Your answer should look like: 1 4/40

Now simplify: 1 1/10

5(x + 8) = - 10

5x + 40 = - 10

5x = - 50

5x ÷ 5 = - 50 ÷ 5

x = - 10

4. A spinner and a number cube numbered 1 to 6 are used in a game. The spinner is divided into 4 equal sections: red.
blue yellow, and green. A player must spin the spinner and roll the cube to move on the game board. What is the
probability of a player's spinning red and rolling a 5 or 6?

Answers

Answer:

1/12 or 1 out of 12

Step-by-step explanation:

Landing on red with the spinner is a 1/4 chance and the chance of rolling a 5 or 6 is 1/3. Multiplying the two fractions gives us the final probability, which is 1 out of 12.

This dot plot is symmetric, and the data set has no
extreme values
What is the best measure of center for this dot plot?
A. The smallest value
B. Either the mean or the median
C. The interquartile range (IQR)
O D. The mean absolute deviation (MAD)


Answers

Answer:

B. Either the mean or the median

Step-by-step explanation:

The given data in the dot plot are;

The number of data points at 7 on the number line = 3 data points

The number of data points at 8 on the number line = 5 data points

The number of data points at 9 on the number line = 3 data points

The mean = (3 × 7+ 5 × 8 + 3 × 9)/11 = 8

The median = The value of the (11 + 1)/2 th = The value of the 6th data point

Therefore, the median = 8

Therefore, given that the distribution of the data points are symmetrical about the number 8 on the number line (5 points at 8 and 3 points each at 7 and 9) the best measure of the center for the dot plot is the mean or the median.

Answer:

B Either the mean or the median

There are 4 yellow, 8 purple, and 3 orange popsicle sticks in a container. Without looking, Kevin selects one popsicle stick from the container. Which color has a 1/5 chance of being chosen?

Answers

Answer:

It would be the orange popsicle sticks

Step-by-step explanation:

Answer:

The color Orange has a 1/5 chance of being chosen.

Step-by-step explanation:

Find the total: 4 + 8 + 3 = 15

Yellow = 4

[tex]\frac{4}{15}[/tex]

[tex]\frac{4}{15}[/tex], cannot be reduced any further so we know the color yellow is not the correct answer.

Purple = 8

[tex]\frac{8}{15}[/tex]

[tex]\frac{8}{15}[/tex], cannot be reduced any further so we know the color yellow is not the correct answer.

Orange = 3

[tex]\frac{3}{15}[/tex] simplifies into [tex]\frac{1}{5}[/tex]

So Orange is the correct answer.

O The median-median regression line is a better prediction.

Step-by-step explanation:

The given median-median line for a dataset is

y 1.133x+ 0.489

The least-squares regression line for the same dataset is

y = 1.068x0.731

The given point is (50,60).

Substitute x=50 in each given equation.

y = 1.133(50) + 0.489

57.139

y = 1.068(50) + 0.731 = 54.131

Since the value of median-median line at x=50 is near to 60 than the value of least-squares regression at x=50.

The median-median line regression line is a better prediction. Therefore the correct option is A.
