Frank wants to know how many people live in each household in his town. He conducts a random survey of 10 people and asks how many people live in their household. His results are shown in the table.
1 6 2 4 4 3 5 5 2 8
Calculate the MAD of the number of people per household.
Answer:
1.6
Step-by-step explanation:
The average of this ten number is (1+6+2+4+4+3+5+5+2+8)/10=4
So the MAD is (|1-4|+|6-4|+|2-4|+|4-4|+|4-4|+|3-4|+|5-4|+|5-4|+|2-4|+|8-4|)/10
=(3+2+2+0+0+1+1+1+2+4)/10
=1.6

~AH1807david and jason have marbles in a ratio of 2:3. together they have a total of 35 marbles . how many marbles dose David have
Answer:
14 marble
Step-by-step explanation:
here's your solution
=> Total number of marble = 35
=> ratio of David and Jason = 2 : 3
=> let the ratio be in x
=> now, 2x + 3x = 35
=> 5x = 35
=> x = 35/5
=> x = 7
=> number of marble with David = 7*2 = 14
=> number of marble with Jason = 7*3 = 21
hope it helps
Answer:
number of marbles that David had=
[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of the yard not inside the fence?
Answer:
[tex]\angle MKJ = 34[/tex]
Step-by-step explanation:
Given
[tex]\angle LKJ = 124[/tex]
Required
Find [tex]\angle MKJ[/tex]
From the attachment:
The measure of [tex]\angle MKJ[/tex] is calculated using the following expression:
[tex]\angle MKJ + \angle LKM = \angle LKJ[/tex]
Where
[tex]\angle LKM = 90[/tex] -- right-angled.
The expression becomes
[tex]\angle MKJ + 90 = 124[/tex]
[tex]\angle MKJ = 124 - 90[/tex]
[tex]\angle MKJ = 34[/tex]

Look at thee isosceles triangle what angle is B?
(I am so so tired is 2 in the morning)
Answer:
m∡b = 50°
Step-by-step explanation:
this is an isosceles triangle so the other base angle also measures 65°
there are 180° in a triangle so m∡b = 180-(65+65) or 50°

What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr
Answer:
50inches
Step-by-step explanation:
Complete question;
The square shown(image attached) has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr a cone with a base circumference of about 25 units a cone with a base circumference of about 50 units a cylinder with a circumference of about 25 units a cylinder with a circumference of about 50 units.
The figure shown is a square
Perimeter of a square = 4L
L is the length of the side of the square
32 = 4L
L =32/4
L = 8units
Since the square is rotated about a line k forming a circular shapr, hence the radius of the circular shape is equal to the length of the side of the rotated square. Hence r = 8units
Get the circumference of the circle
C = 2πr
Substitute r = 8 into the formula
C = 2π(8)
C = 16π
C = 16(3.14)
C = 50.24in
Hence the approximate circumference of the circle is 50inches

Answer:
Option (2)
Step-by-step explanation:
Amount of apples in a box = [tex]2\frac{3}{4}[/tex] pounds
= [tex]\frac{11}{4}[/tex] pounds
Apples used by Sage = [tex]\frac{1}{5}th[/tex] Part of the total amount
= [tex]\frac{1}{5}[/tex]th part of the apples in the box
= [tex]\frac{1}{5}\times \frac{11}{4}[/tex]
= [tex]\frac{11}{20}[/tex] pounds
Therefore, Sage used [tex]\frac{11}{20}[/tex] pounds of the apples.
Option (2) will be the answer.
I need help with this
Answer:
since k is the constant for any proportionality, simply do 48/4 since 48=y and 4=x or y/x, your constant will be equal to 12 as well as ur unit rate point since they said it is the same as your constant, your equation would be y=12x

Find the area of all the shapes and then add them together I believe...
Answer:
468 Square Centimeters
Step-by-step explanation:
Surface area can be calculated by adding the areas of each face on a prism:
The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468please let me know if the answer or explanation is incorrect, hope this helps :)
