Answer:
The number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:
3.0
In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.
The MAD of first set of data is: 1.2
and MAD of second set of data is: 0.4
Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.
Step-by-step explanation: i Just said it 3.0 Hope this help ..lolz <3
pls help i will give brainliest

A barn floor scale drawing measures 5 cm by 7 cm. The scale for the actual barn is 2cm : 10 ft. What is the area of the barn? (WRITE THE NUMBER, ONLY)
Answer:
20
Step-by-step explanation:
Answer:
The answer is 875
Step-by-step explanation:
SO EASY- 2cm is equal to 10ft, so that means 5ft is equal to 1cm.
5*5=25
7*7=35
35*25=x=875

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.
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
84 * 2.5= 210

Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.
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! :)
Find the value of x - this is circle segments.
Answer:
x = 12
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
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?
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.
Answer:
C
Step-by-step explanation:
a(0.62)+4(1.00)/a+4+78/100
Please find the angles
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°
What is the length of road that each of the rollers would cover in one revolution? The volume of each roller is 3 m3 and the length across the front of each roller is 1.8 m.
Answer:
example, such as you could cover 3 miles in distance 1 a a quantity that has both a magnitude/size speed limits on the roads and more junctions in 3 velocities for each section: A = 200 m / 50 s = front stops suddenly. gravitational potential and back as the roller 3 a mass = 1000 m3 × 1000 kg/m3 = 1 × 106 kg.

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?
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 :)

Answer: 112in^2
Step-by-step explanation:
area of rectangle is
10 x 10 = 100 in ^2
then area of the triangle
h x b / 2 = 12 in^2
so 100 + 12 = 112 in^2

Answer:
k is constant of proportionality
Monday: k = 7.5
Tuesday: k = 2
Step-by-step explanation:
The equation for proportionality is y = kx
Take the first line of the table, plug it in and solve for k. Do that with at least 1 other row to be sure k is the same.
15 = (k)(2)
k = 7.5
——————
Same thing for this day. x is the horizontal, y is the vertical.
16 = (k)(8)

Can someone answer this its just boxplots :)))
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 valueThe 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.
