Answer:

15 x 5 would come first

Step-by-step explanation:

PEMDAS

first you do parenthesis, and then multiplication so you would do the multiplication inside of the ( ) first !

Answer:

if your doing PEMDAS then do parentheses but if your not then multiply first.

=============================================================

Explanation:

A full circle is 360 degrees. The pie slices shown represent the various angles of each slice. Each angle expression in that diagram will add up to 360.

Doing this will help us solve for x.

(angleVQR)+(angleRQS)+(angleSQT)+(angleTQU)+(angleUQV) = 360

(21x+4) + (14x-4) + (5x+5) + (5x+5) + (80) = 360

45x+90 = 360

45x = 360-90 ... subtract 90 from both sides

45x = 270

x = 270/45 ..... divide both sides by 45

x = 6

We'll then plug this x value into the angle expression for angle TQU

angle TQU = 5x+5

angle TQU = 5*6+5

angle TQU = 35 degrees

Answer:

C

Step-by-step explanation:

First, find the slope:

Formula for slope:

m = y2 - y1 / x2 - x1

m = -2 - -5 / 0 - -1

m = - 2 + 5 / 0 + 1

m = 3 / 1

m = 3

Next, find the y-intercept:

When x = 0, y = ???

According to the chart, when x = 0, y = -2. This is our y-intercept, also known as b.

Format the answers:

y = 3x + -2

y = 3x - 2

Check your work:

Plug in any x value and the y value should match the chart:

-5 = 3(-1) - 2

-5 = -3 - 2

-5 = -5

Correct

Answer:

40.73

not 100% sure but by comparing to the other answers, its the most logical

Answer:

$40.00

Step-by-step explanation:

Find 1% of 50

50 / 100 = 0.5

Multiply that value by 5

0.5 * 5 = 2.5

Multiply the new value by 4

2.5 * 4 = 10

Subtract

50 - 10 = 40

Answer:

roots are [(5 - [tex]\sqrt{73}[/tex]) / 4] and [(5 + [tex]\sqrt{73}[/tex]) / 4]

Step-by-step explanation:

[-b ± √b² - (4ac)] ÷2a

2x² - 5x - 6 = 0

a = 2

b = -5

c = -6

[5 ± √5² - 4(2)(-6)] ÷ 2(2)

[5 ± √25 - (-48)] ÷ 4

[5 ± √73] ÷ 4

Answer:

63.5, 66.5

Step-by-step explanation:

Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.

Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.

The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:

[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds

This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Answer:

238 degrees

Step-by-step explanation:

Whole circle measures 360 degrees.

Subtract 122 degrees from the whole circle to get 238 degrees.

Answer:

Step-by-step explanation:

In order to solve for x, she had to first subtract 6 on both sides of the equation.  Then divide by 5 on both sides of he equation.  After the division part, she was able to successfully isolate x.

The equation she had to solve was     (C)  5x+6=21

First step:  Subtracting 6 on both sides of equation resulted in

5x = 15

Second step:  Dividing both sides of the equation by 5 resulted in

x = 3

Answer:

The data for Dr. Amine's office is more

symmetrical than the data for Dr. Harris's office.

Step-by-step explanation:

Using visual inspection, Dr. Amine's office data is symmetrical as the median value is well. Positioned in between the box plot with approximately the same width to both left and right of the plot from the median value. While that of Dr. Harris office is clearly skewed.

From the median value and range values, Dr. Harris's office has greater value than Dr. Amine's office, hence the options are false. The interquartile range are also not the same.

Answer:

options man?

Step-by-step explanation:

1/2 = 2/4 = 3/6 = 4/8 = 5/10 = 6/12 = 7/14 = 8/16 = 9/18 = 10/20 = 11/22 = 12/24

1/2 = 25/50 = 50/100 = 100/200 = 150/300 = 200/400 = 250/500
