Answer: AB=12
Los triangulos BCD y ADE son iguales por tener dos lados y el angulo comprendido respectivamente iguales. por tanto AE=DC=4
Luego AB = AE+EB = 4+8 = 12
Answer:
Step-by-step explanation:
Given the data:
34, 18, 29, 60, 44, 51, 65, 68.
Ordered data :
18, 29, 34, 44, 51, 60, 65, 68
The five number summary :
Sample size = 8
Minimum = 18
Lower quartile (Q1) = 1/4 (n+1) = 9/4 = 2.25
(2nd + 3rd term) / 2
= (29 + 34) / 2 = 31.5
Using calculator :
Median (Q2) = 47.5
Upper quartile (Q3) = 62.5
Maximum = 68
2.) With the information above, the museum curator could use this to guide their stock preference by stocking up gifts suitable for adults and youths, stockingbup with children's gift may be a bad options as visitors are atleast 18 years of age.
Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:
B. -32 ft/s; the average change in altitude of the ball each second over that interval.
<h3>What is the average rate of change of a function?</h3>
The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
In this problem, the function is given by:
f(t) = -16t² + 100.
The outputs are given as follows:
- f(0) = -16(0)² + 100 = 100.
- f(0) = -16(2)² + 100 = 36.
Hence the average rate of change is given by:
r = (36 - 100)/(2 - 0) = -32 ft/s.
And the correct option is:
B. -32 ft/s; the average change in altitude of the ball each second over that interval.
