Find the GCF of the two numbers, and rewrite the sum of the two numbers using the distributive property. 3 + 15 A) 1(3 + 5) B) 1(3 × 5) C) 3(1 + 5) D) 3(1 × 5)
Answer:
GCF of the numbers is 3 and it can be written as 3(1+5)
Step-by-step explanation:
Given the expression 3+15
First we need to find their factors
3 = 3×1
15 = 3×5
Since 3 is common to both factors, hence the GCF is 3
Factorize
3+15
= (3×1)+(3×5)
Factoring 3 out
= 3(1+5)
Hence the GCF of the numbers is 3 and it can be written as 3(1+5)

Probability mathematic
Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
Answer:
1/9
Step-by-step explanation:
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Divide the number of events by the number of possible outcomes.

Henry rolls a standard six-sided die, numbered from 1 to 6. Which word or phrase describes the probability that he will roll a multiple of 2?
A certain bile
B unlikely
C an equal chance or 50-50 impossible
D impossible
Answer:
certain
Step-by-step explanation:
Jai rolls a standard six-sided die, numbered from 1 to 6. Which word or phrase describes the probability that he will roll a number between 1 and 6 (including 1 and 6)?
There are 6 possible outcomes for rolling a die numbered from 1 to 6: {1, 2, 3, 4, 5, 6}.
Within that set of outcomes, there are 6 possible ways of rolling a number between 1 and 6 (including 1 and 6): {1, 2, 3, 4, 5, 6}.
6 out of 6 is 1. When something will occur all the time, we say it is certain.

Suppose that the breaking strength of a rope (in pounds) is normally distributed, with a mean of 100 pounds and a standard deviation of 17. What is the probability that a certain rope will break before being subjected to 130 pounds?
Answer:
0.961
Step-by-step explanation:
To answer this, find the area under the standard normal curve to the left of 130 pounds:
Using the function normalcdf( on a TI calculator, we get:
normalcdf(-1000, 130, 100, 17) = 0.961

Soccer - Male; 19 Female; 31
Basketball - Male; 21 Female; 29
Total - Male; 40 Female; 60
What is a two-way frequency table?A two-way or contingency table is a statistical table that shows the observed number or frequency for two variables, the rows indicating one category and the columns indicating the other category.
Given, one hundred people were asked about their favorite sport.
Since the Total number of humans is 50
And female who likes Soccer is 31
Thus, Male who likes Soccer = 50 - 31 = 19
Since the Total number of humans is 50
And female who likes Basketball is 29
Thus, Male who likes Basketball = 50 - 29 = 21
So,
Total males = 21 + 19 = 40
Total number of female = 29 + 31 = 60
about the two-way frequency table.False More males were surveyed than females. (since total male-to-female ratio is 2/3)
True More females like soccer.
True An equal number of people like soccer and basketball.
False Twice as many females as males like basketball.

Kayla rolls two fair number cubes each numbered 1 through 6. She needs to roll a sum of 9 or more to win a game. She rolls the number cubes one at a time. She rolls a 5 with the first number cube.
What is the probability that Kayla will win the game?
Answer:
1/6
Step-by-step explanation:
Starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12). After simplification, the final result is 1/6.

On a field trip to the farm, students counted a combined total of 27 sheep
and cows. There are 15 more sheep than cows. If s represents the number
of sheep and c represents the number of cows, which system of equations
correctly represents this situation
Answer:
s = c + 15
s + c = 27
substitute for s:
(c + 15) + c = 27
2c = 12
c = 6
s = 21
The system of equation which correctly represents the situation is s + c = 27 and s - c = 15.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Given that,
Combined total of sheep and cows = 27
Number of sheep = Number of cows + 15
Let s represents the number of sheep and c represents the number of cows.
s + c = 27
s = c + 15 ⇒ s - c = 15
Hence the system of equation is s + c = 27 and s - c = 15.

What is the value of r in the following diagram.
9
6
Answer:
r = 3.75
Step-by-step explanation:
Using Pythagoras' identity in the right triangle ABC
AC² = BC² + AB²
(r + 6)² = r² + 9²
r² + 12r + 36 = r² + 81 ( subtract r² from both sides )
12r + 36 = 81 ( subtract 36 from both sides )
12r = 45 ( divide both sides by 12 )
r = 3.75

given the inequality 4x-y<=k-6, there is a minimum value of k in order for the point (5,0) to be part of a solution. what is the minimum value?
Answer:
26
Step-by-step explanation:
since the question asks for a value of k where the point (5, 0) is part of a solution, plug 5 into the x value and 0 into the y value:
4x-y<=k-6
4(5)-0<=k-6
20-0<=k-6
20<=k-6
26<=k
In this case, k can be equal to any number that is greater than or equal to 26 for the point (5, 0) to be a solution, but the question asks for the minimum value of k, meaning the smallest value. since the question asks for the smallest value, the answer we're looking for is 26.
