Ex: (A) 19.95÷29.95 and you will get your answers
90cm^3. First, determine the area of the right triangle face, A=1/2(b*h) - 1/2(4.5*5) = 11.25cm^2. This triangle is repeated over 8cm, so we multiply the 11.25cm^2 * 8cm = 90cm^3.
D/r , i think , i’m not sure if it is correct
Answer:
H= 11
Step-by-step explanation:
231 = h x 7 x 3
231 = 21h
/21 /21
H=11
50% of data will be less than 50
Step-by-step explanation:
A normal distribution has the shape of the graph like a bell.
Given

we have to find how much data will be less than 50.
So we have to calculate z-score for 50.

The z-score is zero. As we have to find the number of values less than 50 we will find the area to the left of curve

In order to convert the probability into percentage
=0.50*100
=50%
Hence,
50% of data will be less than 50
Keywords: Probability, Area under the curve
