Volume of the cone is 100 m³
Step-by-step explanation:
- Step 1: Find the volume of the cone with radius = 3 m and height = 7 m
Volume = 1/3 πr²h
= 1/3 × 3.14 × 3² × 7
= 3.14 × 21 = 65.94 ≈ 100 m³ (rounded off to nearest hundredth)
Answer:
0.12 (12%)
Step-by-step explanation:
Step 1: Given data
Probability of rain every day: 70% (0.7)
Step 2: Calculate the probability that it rains every day
The probability that it rains one day is independent of the probability that it rains another day. For independent events, we can calculate the probability that it rains every day by multiplying the individual probabilities. Since the individual probabilities are equal, this is the same as raising the individual probability to the number of days.
P = 0.7⁶ = 0.12
Answer: C) All real values of x such that
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
