Answer Step-by-step explanation:
≤ x ≤
≤ x ≤ 
Answer:
The correct answer is - C. 24.1%
Step-by-step explanation:
Given:
mean μ = 65%
standard deviation δ = 7.1 %
solution:
Prob( X>70) = 1 - Prob(x<70)
= P (x-μ/δ ≥ 70 -65/7.1)
= 1 - Prob( (70-65)/7.1)
= 1 - Prob ( z < 0.7042553)
= 0.24065
the percentage of students scoring 70 or more in the exam
= 24.065*100
= 24.1%
Hello! Your answer is below... Remember : h = height and v = volume
Answer:
H = 15.35 cm
V = 690.75 m^
Step-by-step explanation:
(H= height, V = volume, ^= square, √ = square root )
1. divide 9/2
=4.5 cm
2. use the pythagorean theorem
H=√16^-4.5^
H=15.35
if your looking for volume
1. use the formula for volume of the pyramid which is:
1/3 x base area x height
or
base area x height /3
2. then you substitute
1/3 x (9)(15) x 15.35
or
(9)(15) x 15.35 /3
V= 690.75 m^
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
:)
It would need 288 cubes to fill up the prism.
