Can someone answer this its just boxplots :)))

Answers

Answer:   50%

Explanation:

The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:

Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest value

The median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.

If the simple interest on a principal amount of $6000 for 7 years is $2,520, then what is the interest rate as a percent?

Answers

Answer:

6%

Step-by-step explanation:

first multiply $6000 by 7 years then divide 2520 by 42000 to get 0.06

6% because interest= principal amount x rate x time / 100

So 2520=6000xRx7 / 100 = 6%

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many miles is the Jackson’s trip from Boston to New York?

Explain how you solved this problem in the box below. Include a description of your strategy and your answer in your explanation.

Answers

Answer:

84 is .4 of the trip

40% times 2.5 is 100% (40+40+20)

so, multiple 84 by 2.5 and that's the answer

84 * 2.5= 210

Answer:

84 is .4 of the trip

40% times 2.5 is 100% (40+40+20)

so, multiple 84 by 2.5 and that's the answer

Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°

again

<7=<4+<5=90°+40°=130°

Carla's library account showed that she owed $4.00 in late fees. She made a payment of $7.00. She then lost a library book and was assessed a $12.00 fine. If Carla then makes a payment of $20, what is her balance after the payment?

Answers

Answer:

$9

Step-by-step explanation:

ok so this is what she owes- **i'm 'separating' them to make it easier**

$4 and $12 so let's add those together-

4+12=$16 so she owes 16 dollars in fines and late fees

and let's remember that she paid $7 for her late fee and assuming that she gets her $3 back she has $3 so far then for the 12 dollar fine she pays 20 dollars, and we're assuming that she gets back $6

she should have $9 left

good luck :)

Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.

Answers

Answer:

Circumference = 81.64

Step-by-step explanation:

The formula for finding circumference is C = pi(d). Since you don't have the diameter, but you do have the radius (which is half of the diameter), you will multiply 13 by 2, or 13 x 2. 13 x 2 = 26. So, the diameter is 26.

Fill in what you know: C = 3.14(26)

Now, all you have to do is multiply 3.14 and 26, which equals 81.64.

Hope this helps! :)

For finding circumference you want to double the radius first to get a diameter. 13mm*2= 26mm so the diameter is 26 now we need to multiply it by 3.14 (the first 3 digits of pi). 26mm*3.14= 81.64mm Hope this helped!!

Step-by-step explanation:

The square of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 8(8 + 10) = 8 × 18 = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12

How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?

Answers

Answer:

3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.

Step-by-step explanation:

To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:

50 + 0.62X = 78

0.62X = 78 - 50

0.62X = 28

X = 28 / 0.62

X = 45.16

100 - 45.16 = 54.84

54.84 = 4

45.16 = X

45.16 x 4 / 54.84 = X

180.64 / 54.84 = X

3.29 = X

Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
