Draw a number line, or look for a number line online.

a. Count the number of units from 5 to 0. It is 5.

b. Count the number of units from -5 to 0. It is 5.

c. |5| means the absolute value of 5, and it represents the distance 5 is from 0 on the number line. The answer is 5.

d. |-5| means the absolute value of -5, and it represents the distance 5 is from 0 on the number line. The answer is 5.

Answer:

7.6

Step-by-step explanation:

mean = [weights] / amount of weights

m = 10 + 7 + 6 + 10 + 13 + 10 / 6

m = 46 / 6

m = 7.66666666 (recurring)

m = 7.6

Write an equation of the cosine function with amplitude pi/2 and period 3

juin [17]

Answer:

$y = \frac{\pi}{2}cos(\frac{2\pi}{3}x)$

Step-by-step explanation:

Given

$Amplitude = \frac{\pi}{2}$

$Period = 3$

Required

Write the equivalent cosine function

The general formula is:

$y = acos(bx)$

Where

$amplitude = |a|$

$period = \frac{2\pi}{b}$

Substitute $\frac{\pi}{2}$ for amplitude in $amplitude = |a|$

$|a| = \frac{\pi}{2}$

$a = \frac{\pi}{2}$

Substitute 3 for period in $period = \frac{2\pi}{b}$

$\frac{2\pi}{b} = 3$

<em>Multiply both sides by b</em>

$2\pi = 3b$

<em>Divide through by 3</em>

$b = \frac{2\pi}{3}$

Hence;

$y = acos(bx)$ becomes

$y = \frac{\pi}{2}cos(\frac{2\pi}{3}x)$

Rearranging formula

allochka39001 [22]

Answer:

Arlo's weight = 52.3 kg

Explanation:

Let Arlo be "x"

Then,

Arlo = x

Bert = x+20 (Because Bert is 20 heavier than Arlo)

Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)

Donnie = $\frac{x+20}{2}$ (Because Donnie is half of Bert's weight)

Average = 57

Step by step Calculations:

57 = $\frac{(x) + (x+20) + (x+20-5) + (\frac{x+20}{2} )}{4}$ (The whole divided by 4 because the total people is 4)

57*4 = x + x + 20 + x + 20 - 5 + $\frac{x+20}{2}$

228 = 3x + 35 + $\frac{x+20}{2}$

228 - 3x - 35 = $\frac{x+20}{2}$

193 -3x = $\frac{x+20}{2}$

2(193 - 3x) = x + 20

386 - 6x = x + 20

386 - 20 = x + 6x

366 = 7x

x = $\frac{366}{7}$

x = 52.3 kg (corrected to 3 significant figures)

Therefore Arlo's weight is 52.3 kg

Which scatterplot shows the correct division for using the Divide-Center of Data method to draw the trend line?

WARRIOR [948]

The appropriate scatter plot which depicts the correct divison for using Divide center to draw trend line is the plot B(second plot)

In other to perform a correct divison of points using the divide center method of drawing a trend line;

• The dividing vertical line must be drawn at the midpoint(a position where there are equal number of data points to the left and right of the vertical line.

Evaluating the options given based on this condition, only option B has it's vertical line dividing the 6 data points into two equal portions (3 on either side of the graph)
