Answer:
The mean = 17.54
Step-by-step explanation:
Form a table as below;
Interval Frequency{f} Midpoint of frequency{x} fx
1-7 19 4 76
8-10 14 9 126
11-15 15 13 195
16-20 20 18 360
21-35 10 28 280
36-50 13 43 559
Sum 91 1596
The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency
The mean= 1596 / 91
The mean = 17.54

Answer:
x = 26
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
(2x)° +50° +(3x)° = 180°
5x +50 = 180 . . . . . . . divide by °, collect terms
x +10 = 36 . . . . . . . . . divide by 5
x = 26 . . . . . . . . . . . . . subtract 10

1 s = 3 m
2 s = 6 m
42/3 = 14
14 s = 42 m
16 X 3 = 48
16 s = 48 m
72/3 = 24
24 s = 72 m
m = s X 3
s= m/3

Traveling 10 meters in 1/3 of a second how fast was it going
Answer:
I guess he was traveling 30 meters every second.
(Which is pretty slow to be honest)
Step-by-step explanation:
This question doesn't really make sense since it says it right there he traveled 10 meters in 1/3 of a second. But I'm guessing that you want to find out how many meters per second.
Since 1/3 multiplied by 3 = 1
Then 10 multiplied by 3 = 30.
So, he traveled 30 meters every second.
The cost of a sweater at a clothing store was $35. The sweater went on sale at a discount of 20% off the original price. What is the sale price of the sweater?
Answer:
$28
Step-by-step explanation:
First, we have to find 20% of 35.
We can do that by multiplying 0.20 by 35. (0.20 x 35)
After multiplying them, we get a product of $7.
Since the sweater went on sale and they took 20% off of the original price, we have to subtract $7 from the original price of $35. (35 - 7)
We can solve that to get us the discounted price of $28
(sorry if this is confusing but I hope it helped)

Equating expressions for the hypotenuse, we have ...
10x = 2x +8
8x = 8 . . . . . . . . subtract 2x
x = 1 . . . . . . . . . . divide by 8
Equating expressions for the bottom legs, we have ...
y +2x = 10x -y
2y = 8x . . . . . . . . add y-2x
y = 4x = 4(1) . . . . divide by 2, substitute for x
y = 4

i need help with this question
Answer:
726 ft
Step-by-step explanation:
The perimeter is the sum of the 4 sides, that is
x + x + 274 + x + 27 + x + 74 = 3279, that is
4x + 375 = 3279 ( subtract 375 from both sides )
4x = 2904 ( divide both sides by 4 )
x = 726
