Answer:
40 m^3
Step-by-step explanation:
Volume of a pyramid = 1/3 * base area * height
base area = 4 x 4
1/3 * (4x4) * 7.5 = 40 m^3
I am not sure! What is the original equation?
Answer:
It is arithmetic progression
Step-by-step explanation:
If wwe see, the numbers are going down by 3 each time, therfore the common difference is 3
Option A:
m∠B = 42.1°
Solution:
Given data:
b = 18, c = 15 and m∠C = 34°
Using sine formula:

Substitute the given values.

Do cross multiplication.

Divide by 15 on both sides.





Switch the sides.
m∠B = 42.1°
Option A is the correct answer.
Answer:
c. 0.810
Step-by-step explanation:
Given, total % of satisfactory packages = 90% = 0.90
Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)
Hence, Probability of selecting two packages that re satisfactory
P(Selecting 2 satisfactory packages) = (0.90)^2
P(Selecting 2 satisfactory packages) = 0.90*0.90
P(Selecting 2 satisfactory packages) = 0.810
Note: We are selecting product since the chance of selecting in each trials are independent.
