Answer:
39.6 cm²
Step-by-step explanation:
The formula for the area of a trapezoid is given as:
Area of a Trapezoid = 1/2(a + b) h
Where, from the question:
a = 8.9 cm
b = 5.5 cm
h = 5.5cm
Hence,
1/2 (8.9cm + 5.5cm) × 5.5cm
= 1/2 × 14.4 cm × 5.5 cm
= 39.6 cm²
Area of the Trapezoid = 39.6 cm²
Answer:
B, or in other words, the last solution is correct.
Step-by-step explanation:
Parallel lines haves the same slope, meaning that Street 2 will have the same slope as Street 1. Street one, according to the graph, has a slope of 1. Thus, Street 2 will have a slope of 1.
By this logic, we can get rid of A and C as choices, as they have a slope of -2 or 2. Now we have choices B and D left.
It can't be B, as the slope is -1, not 1.
Therefore, the answer is D.
Answer:
Step-by-step explanation:
Given that x is a random variable from a binomial distribution with n = 40 and p = 0.9.
We find that mean = np= 36 and variance = npq = 3.6
Std dev = square root of variance = 1.897
When we approximate binomial to normal we say
X' is Normal with mean = 36 and std dev = 1.897
X' is N(36, 1.897)
Note:
The condition for binomial approximating to normal is p should be close to 1/2
Here p is 0.9 and also nq=4 is very small.
So normal approximation may not give accurate results.
