The circumference of a circle that has a radius of 70 feet is most nearly
A. 220 feet.
B. 440 feet.
C. 660 feet.
D. 690 feet.
Answer:
B 440 feet
Step-by-step explanation:

= 2(3.14)70 feet
= 6.28(70 feet)
= 439.6
439.6 is approximate to 440 feet
Expand the logarithm. Simplify, if possible.
log7(49^w)
Step-by-step explanation:
Let x = log7(49^w).
We have 7^x = 49^w.
=> 7^x = (7^2)^w
=> 7^x = 7^2w.
=> x = 2w.
Therefore log7(49^w) = 2w.

Answer:
x = 30°
Step-by-step explanation:
Given that,
∠A = x°
∠B = 2x°
∠C = 90°
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°.
ATQ,
x° + 2x° + 90° = 180°
3x° = 180°-90°
3x° = 90°
x° = 30°
So, the value of x is 30°.
Answer:
3x+90=180
3x=90
x=30

Which distribution is most nearly appropriate to describe_______the number of fatalities in Texas in a given year due to poisonous snakebites.
Answer: Poisson distribution
Step-by-step explanation:
The Poisson distribution simply measures the chance for an event occuring based on a particular period of time. It is typically useful for finding the probability of events that have low probabilities of occuring.
Therefore, the distribution that will be ideal in knowing the number of fatalities in Texas in a given year due to poisonous snakebites is the poisson distribution.

Answer:
g(3) = 0
Step-by-step explanation:
You know g(x) = 3x - 9. So, to find g(3), you have to replace x by 3 on the other side.
g(3) = 3(3) - 9
You can solve this.
g(3) = 9 - 9
g(3) = 0

A committee is to consist of two members. If there are seven people
available to serve on the committee, how many different committees can
be formed
Answer:
2
Step-by-step explanation:
Common Sense
The number of different ways committees can be formed will be 21.
What are permutation and combination?A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
A committee is to consist of two members.
If there are seven people available to serve on the committee.
If two people are selected from the group of seven people.
Then the number of different ways committees can be formed will be
⇒ ⁷C₂
⇒ 7! / [(7 – 2)! x 2!]
⇒ 7! / [5! x 2!]
⇒ 7 x 6 x 5! / [5! x 2 x 1]
⇒ 7 x 6 / 2
⇒ 7 x 3
⇒ 21
Thus, the number of different ways committees can be formed will be 21.
