The ages of two groups of karate students are shown in the following dot plots:
picture shown below:
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean
Answer:
Group A has less variability in the data.
Step-by-step explanation:
Since the range of group a is 10 (14 - 4), while group B has a range value of 19 (26 - 7) therefore group A has less variability in the data.

An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
The angles are 69.2 degrees and 20.8 degrees
Step-by-step explanation:
Complementary angles, when added together, = 90°
We’ll call the first unknown angle a and the second angle b
b = a - 48.4
a + b = 90
So let’s substitute in for b in the second equation:
a + a - 48.4 = 90
2a - 48.4 = 90
2a = 138.4
a = 69.2
69.2 - 48.4 = 20.8 = b
Now, does a + b = 90?
69.2 + 20.8 = 90
Lmk if you have questions

A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 38 centimeters, and the length of the other leg is 29 centimeters. The student incorrectly says that the length of the hypotenuse is 8.2centimeters. Answer parts a and b.
Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
The length of the hypotenuse of the right triangle to the nearest tenth of a centimeter is ..... cm
(Round to the nearest tenth as needed.)
Answer:
1,142.5 or 1,143
Step-by-step explanation:
Part A: Start by writing out the equation a2 + b2 = c2. Since both sides a and b are known, fill it in. So, now it is 38 squared + 29 squared = c2. Next, you have to find the square roots for both sides, or legs. For 38 squared, it will be 38 x 38 = 1,444. For 29 squared, it will be 29 x 29 = 841. Now that we both legs, we add that together: 1,444 + 841, which equals 2,285. Then, you need to divide 2,285 by 2, which is 1,142.5
Since you need to round, it would be 1,143.
Part B: 1,143
If 47 Mph was a unit rate, how many hours would it take to travel 1 Mph?
Answer: um i think you asked the question wrong. But ok.
Step-by-step explanation:
= 47 miles per hour
This is a fraction equal to
47 miles ÷ 1 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
47 miles ÷ 1
1 hours ÷ 1
=
47 miles
1 hour
=
47 miles
hour
= 47 miles per hour
Answer:
It would take you a total of .021 of an hour to get there.
Step-by-step explanation:
So, you are asking if 47 mph was a unit rate, how long would it take to travel 1 mile? Ok, so you would convert this to a unit rate, which would be 1 hour.47 miles because you are trying to get the 47 to a 1. Next, you will divide both numbers by 47, giving you .0212765957/1. This rounds to .021/1.
Hope this helps! :)
Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?
Answer:
$3.50
Step-by-step explanation:
to find the range you take the highest number and the lowest number and subtract them
so with that, let us do just that-
$5.75, $3.75, $3.25, $2.25
$5.75-$2.25
=$3.5
and since we're dealing with money we must add a '0' to the end of the decimal- $3.50
good luck :)
i hope this helps

Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84
