Answer:
Class width = 9
Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.
Step-by-step explanation:
We are given;
Highest value = 82
Lowest value = 20
Frequency = 7
Formula for class width is;
Class width = (Highest Value - Lowest Value)/number of classes
Class width = (82 - 20)/7
Class width = 8.8 ≈ 9
Now,since class width is 9, limits between 20 and 82 would be done at intervals of 9.
Thus;
Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.

Answer:
134 degrees
Step-by-step explanation:
a triange has a total of 180 degrees
this means the 2 angles in the are equal to
180-(last angle)=x+102
the exterior angle is also 180-(last angle)
thus you can set the two equal to each other
(4x+6)=x+102
move 6 and x
3x=96
x=32
plug in
(4(32)+6)=134
to check
180-134=46(last angle of the triangle)
32+102+46=180 (true)
Answer: 6
Step-by-step explanation:
Since Pam has 4 yards of fabric and she needs 2/3 yards of fabric for each curtain, the number of curtains that Pam can make with the fabric she has will be the total yards of fabric that she has divided by the fabric needs for each curtain. This will be:
= 4 ÷ ⅔
= 4 × 3/2
= 6
Therefore, she will make 6 curtains
