Answer:
part a: 52%
part b: 0.4
part c: 0.24
Step-by-step explanation:
For part one, you find the frequency of the number of people that are less that 20. You add the number of tics in each bar and you divide by the total.
so for part a it is (7+6+9+4)/ (7+6+9+4+4+12+8)
for part b you add up the values that are greater than 25(less than 35)
(12+8)/total
part c you find the number of people between 25 and 30
that's 12
over total
12/total
The answer is C (EF and HI)
This is because both lines pass through the centre A, meaning both are diameters. Hence, they are equal in length.
The perimeter of a rectangle si length + length + width + width or 2l + 2w. Substitute your values in to get 2(70) + 2(65) → 140 + 130 → 270 feet
84
Step-by-step explanation:
All three angles add up to 180 degrees.
Since it is a right triangle, there is a 90 degrees angle. And we know another angle is 6 degree. So we use the formula: 180 - (known angle + known angle) = unknown angle
Plugging in the information we get: 180 - (90 + 6) = x
180 - 96 = 84
So x = 84
We can check our work by adding all known angles to see if it is equal to 180 using the formula known angle + known angle + known angle = 180 degrees
Plugging in the information we get: 90 + 6 + 84 = 180
96 + 84 = 180
180 = 180
So the answer 84 is correct
