Of a group of 500 people, 60 are fit enough to climb Mount Shasta in California. The group has 300 women and 200 men. 12% of the men are fit to climb the mountain. What is the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta?
Answer and Step-by-step explanation:
t is 59/125. Allow me to disclose to you why P(Man∪Fit)=P(Man)+P(Fit)−P(Man∩Fit)=200500+60500−24500=59125

When Lou started his current job, his employer told him that he would receive two vocation days for each full year he worked. How long will it take him to earn 18 paid vacation days?
By solving a linear equation, we will see that he needs to work for 9 years.
How long will take Lou to earn 18 vacation days?We know that for each year that he works, he gets 2 vacation days.
So we can write the linear equation:
y = 2*x
Where y is the number of vacation days, and x is the number of years that he worked.
We want to find the value of x such that y = 18, then we need to solve:
18 = 2*x
Solving for x w get:
18/2 = x = 9
This means that to get 18 vacation days, he needs to work for 9 years.

Consider the polynomial 9x2 – 16. What is the value of ac? What is the value of b? What two numbers multiply to get ac and add to get b? The factored form of 9x2 – 16 is
The value of ac for the quadratic expression 9x^2 - 16 is -144. The value of b is 0, as it represents the coefficient of x, which is absent in the expression. Therefore, we do not need two numbers that multiply to ac and add to b; the expression is factored using the difference of squares as (3x + 4)(3x - 4).
Explanation:The polynomial 9x2 − 16 is a quadratic expression that can be factored using the difference of squares method. To answer the questions:
The value of ac is the product of the coefficient of x2 and the constant term, which in this case is 9 × (− 16) = − 144.The value of b in the standard form ax2 + bx + c is the coefficient of x, which is 0 since there is no x term in the original expression.To factor, we need two numbers that multiply to ac (which is − 144) and add up to b (which is 0). However, this step is not applicable as the polynomial is already in the form a2 − b2 and will be factored as a difference of squares.The factored form of the polynomial is (3x + 4)(3x − 4).Bob has 36 candy bars and eats 29. What does he have now?
The number of candies Bob left by subtraction will be 7.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
The group's total number of items decreases or becomes lower when we subtract from it.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
As per the given,
Total number of candies = 36
Number of candies Bob ate = 29
Left out = 36 - 29 = 7
Hence "The number of candies Bob left by subtraction will be 7".

Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cooler alone without the tax?
For the cost of the cooler, solve:
106% of cost of cooler = $7.95
To find the total bill in terms of the cost of the cooler :
100% of cooler price
+ 6% of cooler price (tax)
--------------------------------------------
106% of cost (7.95)
Now, solve this problem.
106% of $ _______ = $7.95

An _____ angle of a triangle is equal to the sum of the two remote interior angles
If angleA and angleB are supplementary angles, and angleA = 63°, find the measure of angleB. A. B = 27° B. B = 63° C. B = 117° D. B = 153°
Answer: C. B=117°.
Step-by-step explanation:
We know that if a pair of angle are supplementary then their sum is added up to 180 degrees.
Given : angle A and angle B are supplementary angles.
i.e [tex]\angle{A}+\angle{B}=180^{\circ}[/tex]
Also, angle A = 63°
i.e [tex]63^{\circ}+\angle{B}=180^{\circ}[/tex]
i.e [tex]\angle{B}=180^{\circ}-63^{\circ}[/tex]
i.e [tex]\angl{B}=117^{\circ}[/tex]
Hence, the measure of angleB is 117°.

A school offers two summer sports: lacrosse and tennis. There are 438 students in all. Of this number, 52 participate in lacrosse and 94 participate in tennis. Nobody does both. What fraction of the students participate in a sport? Write the fraction in simplest terms.
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
We have been given that there are 438 students in all. Of this number, 52 participate in lacrosse and 94 participate in tennis.
Our required fraction would be:
[tex]\frac{\text{Students participant in lacrosse + Tennis}}{\text{Total students}}[/tex]
[tex]\frac{52+94}{438}[/tex]
[tex]\frac{146}{438}[/tex]
[tex]\frac{146*1}{146*3}[/tex]
[tex]\frac{1}{3}[/tex]

B: It translates the graph to the left 1 unit.
C: It translates the graph up 1 unit
D: There is no change in the graph.
C- it translates the graph up 1 unit.
Answer:
C

[tex]y=log_5(x)+1[/tex]
Here parent function is [tex]y=log_5(x)[/tex]
If any number is added or subtracted at the end of parent function then we we move up or down
when we compare [tex]y=log_5(x)+1[/tex] with parent function , +1 is added at the end.
So the graph will be translated 1 unit up
Answer : C: It translates the graph up 1 unit

which system of inequalities is graphed below
Answer:
y > x² - 6
y < x² + 2 Option A
Step-by-step explanation:
Given that,
Two parabolic inequality's graph is given.
If we graph inequality y > x² - 6
it shaded the upper part of graph because greater than sign is given.
If we graph inequality y < x² + 2
it shaded the lower part of graph because less than sign is given.
So, common shaded part is mid of both the graph.
Final answer is:
y > x² - 6
y < x² + 2
That's the final answer.
