Answer:

4. The mean and median age are most likely to be same for the students in Math 1.

Step-by-step explanation:

We have been given two box plots that show the ages of college students in different math courses. We are asked to choose the true statement about these box plots.

1. The median age of the students in math 1 is greater than the median age of the students in math 2.  

We can see from our given box plots that median age for both Math 1 and Math 2 is 19 that is represented by vertical middle line of box, therefore, 1st statement is not true.

2. The median age of the students in math 1 is less than the median age of the students in math 2.

Since median ages for students in Math 1 and Math 2 are same (19), therefore, 2nd statement is not true.

3. The mean and median age are most likely same for both sets of data.

We can see that box plot for ages of Math 1 students is symmetric, therefore, both mean and median will be same for Math 1 students.

The box plot representing ages of Math 2 students is skewed right as it has an outlier as 23, therefore, its mean age will be greater than median age.

Therefore, 3rd statement is not true either.

4. The mean and median age are most likely to be same for the students in Math 1.

We can see that box plot representing ages for Math 1 students is symmetric and its whiskers are equidistant from median. So both mean and median age are same that is 19, therefore, 4th statement is true.

Step-by-step explanation:

Since we know they are similar triangles

8                15

---------- = -----------  

120              bridge

Using cross products

8 * bridge = 15* 120

8* bridge = 1800

Divide each side by 8

8/8* bridge = 1800/8

bridge = 225

Answer:

225m

Step-by-step explanation:

the 2 triangles shown are similar by AAA

so their sides are in the same ratio

bridge/15 = 120/8

bridge length = 15*15 = 225m

Answer:

4.6

Step-by-step explanation:

8.1 + (-3.5) = 8.1 - 3.5

4.6

The formula of a circumference is:

[tex]C=2\pi r[/tex]

r - radius

or

[tex]C=d\pi[/tex]

d - diameter

We have d = 12cm. Substitute:

[tex]C=12\pi\ cm[/tex]

One-fourth of the circumference:

[tex]\dfrac{1}{4}C=\dfrac{1}{4}\cdot12\pi=3\pi\ cm\approx3\cdot3.14=9.42\ cm[/tex]

Answer:

[tex]\frac{c-a}{2}[/tex]

Step-by-step explanation:

given [tex]\frac{a}{2x-c}[/tex] = - 1 ( cross- multiply )

- (2x - c ) = a ( distribute left side )

- 2x + c = a ( subtract c from both sides )

- 2x = a - c ( multiply both sides by - 1 )

2x = c - a ( divide both sides by 2 )

x = [tex]\frac{c-a}{2}[/tex]

Answer:

x = [tex]\frac{(a - c)}{-2}[/tex]

Step-by-step explanation:

a/(2x-c) = -1

The first step is to multiply both sides by (2x - c)

(2x - c)a/(2x-c) = -1(2x - c)

a = -2x + c

a - c = -2x + c - c

a - c = -2x

Divide both side by -2

(a - c)/-2 = x

∴ x = [tex]\frac{(a - c)}{-2}[/tex]

Answer:

( [tex]\frac{11}{2}[/tex], 8)

Step-by-step explanation:

Find the midpoint using the midpoint formula

midpoint = [ [tex]\frac{1}{2}[/tex](3 + 8), [tex]\frac{1}{2}[/tex](2 + 14)] = ( [tex]\frac{11}{2}[/tex], 8)

Answer: (5.5, 8)

Step-by-step explanation:

We know that midpoint (x,y) of a line XY having points having points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by :-

[tex]x=\dfrac{x_1+x_2}{2}\ ;\ y=\dfrac{y_1+y_2}{2}[/tex]

Then similarly, the midpoint of AB with endpoints A(3,2) and B (8,14)  will be :_

[tex]x=\dfrac{3+8}{2}\ ;\ y=\dfrac{2+14}{2}\\\\\Rightarrow\ x=\dfrac{11}{2}\ ;\ y=\dfrac{16}{2}\\\\\Rightarrow\ x=5.5\ ;\ y=8[/tex]

Hence, the midpoint of AB with endpoints A(3,2) and B (8,14) = (5.5, 8)

Answer: The plan with 250 minutes is best because she Maximus uses only 245 minutes per month so just 5 min to spare. Also i used mental math

Step-by-step explanation:

1470 divided by 6 equals= 245 minutes exactly unless Katherine had rounded her answer

Final answer:

To determine the best cell phone plan for Katherine, compare the cost per minute for each plan. The second plan, which allows up to 350 minutes per month for $65, has a lower cost per minute.

Explanation:

To determine the best cell phone plan for Katherine, we need to compare the cost per minute for each plan.

For the first plan, Katherine gets 250 minutes for $49, which means the cost per minute is $49/250 = $0.196 per minute.

For the second plan, Katherine gets 350 minutes for $65, which means the cost per minute is $65/350 = $0.1857 per minute.

Since the cost per minute is lower for the second plan, Katherine should choose the plan that allows up to 350 minutes per month for $65.

Answer:

[tex](3x+5)+\frac{28}{2x-4}[/tex]

Step-by-step explanation:

Since,

The volume of a rectangular prism = Base area × Height,

Given,

Volume of the rectangular prism = [tex]6x^2-2x+8[/tex]

Base area = 2x - 4

Let h be the height,

[tex]\implies 6x^2-2x+8=(2x-4)h[/tex]

[tex]\implies h = \frac{6x^2-2x+8}{2x-4}[/tex]

By long division ( shown below ),

[tex]h=(3x+5)+\frac{28}{2x-4}[/tex]

Which is the required expression that represents the height.

Answer:

[tex](3x+5) + \frac{14}{x-2}[/tex]

Step-by-step explanation:

We are given the following information in the question:

Volume of rectangular prism =

[tex]6x^2 - 2x + 8[/tex]

Area of base of prism =

[tex]2x -4[/tex]

Formula:

[tex]\text{Volume of Prism} = \text{Area of base}\times \text{Height of prism}\\\\\text{Height of prism} = \displaystyle\frac{\text{Volume of Prism} }{\text{Area of base}}[/tex]

Putting the values we, get,

[tex]\text{Height of prism} = \displaystyle\frac{6x^2 - 2x +8}{2x-4} = \frac{2(3x^2-x+4)}{2(x-2)}= (3x+5) + \frac{14}{x-2}[/tex]

Hence, the height of the prism is given by the expression [tex](3x+5) + \frac{14}{x-2}[/tex]

Answer:3.25$

Step-by-step explanation:

If one paperback book is 0.25 and you buy 3 of them, (0.25 x 3) is 0.75 and a hardcover is 0.50 per book, (0.50 x 5) is 2 dollars and 50 cents and if you add the two, you will get 3.25$

The amount of money to spend to buy 3 paperback books and 5 hardback books is,

⇒ $3.25

Given that,

The cost of Used paperback books is $0.25.

And, cost of hardback books is $0.50

Here, the cost to buy 3 paperback books is,

⇒ [tex]3 \times 0.25[/tex]

⇒ $0.75

And, the cost of 5 hardback books is,

⇒ [tex]5 \times 0.50[/tex]

⇒ $2.50

So, the total cost of 3 paperback books and 5 hardback books is,

⇒ $0.75 + $2.50

⇒ $3.25

Answer:

y = 5x + 29

Step-by-step explanation:

y=5x+2

Given equation is in the form of y=mx+b

Where m is the slope = 5

and b is the y intercept = 2

When the lines are parallel then their slopes are equal

So the slope of parallel line is also 5 (m=5)

Given that the line passes through (-6,-1)

We use point slope formula

y-y1= m (x-x1)

m=5, x1= -6, y1=-1

Plug in all the values

y - (-1) = 5(x-(-6))

y + 1= 5 (x+6)

y + 1= 5x + 30

Subtract 1 on both sides

y = 5x + 29

Answer:

The unit rate is 0.14 cents per ounce.

Step-by-step explanation:

Divide 3.92 by 28 to find out how much the trail mix is per ounce.

The unit rate of Dmitri's trail mix purchase is $0.14 per ounce, calculated by dividing the total cost by the total weight.

To find the unit rate of Dmitri's trail mix purchase, we divide the total cost of the trail mix by the total weight of the trail mix. Dmitri bought 28 ounces of trail mix for $3.92, so we perform the following calculation:

Unit Rate = Total Cost / Total Weight

Unit Rate = $3.92 / 28 ounces

Unit Rate = $0.14 per ounce

Therefore, the unit rate is $0.14 per ounce. This means that for every ounce of trail mix, Dmitri paid $0.14.

Answer: h=14

Step-by-step explanation:

7h-5(3h-8)=-72

7h-15h+40=-72 > I distributed the -5(3h-8) to get rid of parenthesis

-8h+40=-72 > I combined the like terms 7h-15h

-8h=-112 > I subtracted 40 from both sides

h=14 > I divided -8 from both sides

The solution is h = 14.

Given: Equation

7h - 5(3h - 8) = -72

Now, we will solve the equation for the value of h.

⇒ 7h - 5(3h - 8) = -72

⇒ 7h - 15h + 40 = -72

⇒ 7h - 15h = -72 - 40

⇒ -8h = -112

Dividing both sides by -8, we get:

⇒ h = 14

Therefore, the solution of the given equation is h = 14.
