Answer:
7. Mean = 48
Median = 47.5
Mode = 72
Range = 66
8. Mean= 59.625
Median = 61
Mode = 90
Range = 79
9. Mean = 31.57
Median = 32
Mode = 46
Range = 34
10. Mean = 42.11
Median = 36
Mode = 51
Range = 51
Step-by-step explanation:
Mean is the average. Mode is the number that appears the most. Median is the middle number. Range is the biggest number minus the smallest number.
Hope this helps.
Answer:
7d+11
Step-by-step explanation:
Pretty much just addition.
3d+4d+2+9
(3d+2)+(4d+9) = 7d+11.
the surface area of the above triangular prism is 156 square inches.
Step-by-step explanation:
multiply the sum of the triangle sides by the height of the prism and add the values together for the answer, remembering to include the correct unit of measurement.
Q1. Look at the picture.
Q2. Look at the picture.
Q3.
Put the value of x = 2 to the equation 3x + y = 5:
<em>subtract 6 from both sides</em>
Q4.
Substitute (*) to (**):
<em>use distributive property</em>
<em>add 33 to both sides</em>
<em>divide both sides by 11</em>
Put the value of m to (*):
Q5.
w - width
3w - length
24 in - the sum of length and width
The equation:
<em>divide both sides by 4</em>
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground
