Answer:
Step-by-step explanation:
<h3>
Sphere:</h3>
1) a) r = 7 cm
= 4*3.14 * 7 * 7
= 615.44 cm²
b) r= 8.4 cm
Surface area = 4*3.14*8.4*8.4
= 887.04 cm²
<h3>Hemisphere:</h3>
a) r = 6 cm
= 3 * 3.14 * 6 * 6
= 339.12 cm²
Answer:
B.) the number of tents the army orders
Step-by-step explanation:
The word problem does not speak of any prices or tent sizes so it cant be A or C
Answer:
2(2x + 5)(2x - 5)
Step-by-step explanation:
2(2x + 5)(2x - 5)
= (4x + 10)(2x - 5)
= 8x² - 20x + 20x - 50
= 8x² - 50
Answer:
True.
Step-by-step explanation:
A probability distribution is a listing of all the outcomes of an experiment and the probability associated with each outcome. Probability distribution is associated with the following characteristics or properties;
1. The outcomes are mutually exclusive.
2. The list of outcomes is exhaustive, which simply means that the sum of all probabilities of the outcomes must equal one (1).
3. The probability for a particular value or outcome must be between 0 and 1.
Since a probability distribution gives the likelihood of an outcome or event, a single random variable is divided into two main categories, namely;
I. Probability density functions for continuous variables.
II. Discrete probability distributions for discrete variables.
For example, when a coin is tossed, you can only have a head or tail (H or T).
Also, when you throw a die, the only possible outcome is 1/6 and the total probability for it all must equal to one (1).
