The hockey stick that Erik wants to purchase is $95.00. He knows the price will increase by 15% by the end of next month. Erik needs to calculate the new price of the hockey stick. He solved the problem using the steps below
The new price of the hockey stick based on the information is $109.25.
How to calculate the value?From the information, the hockey stick that Erik wants to purchase is $95.00. He knows the price will increase by 15% by the end of next month.
Therefore, the new price will be:
= $95 + (15% × $95)

Use completing the square to solve for x in the equation (x minus 12) (x + 4) = 9.
The solution fo the equation by completing the square is x = 12.544 or -4.544
What is completing the square method?Completing the square method is a method of solving quadratic equations in which the equation is converted into a perfect square binomial.
How to use completing the square to solve the equation?Given (x - 12)(x + 4) = 9
Expanding the brackets, we have
x² - 12x + 4x - 48 = 9
x² - 8x - 48 = 9
x² - 8x - 48 - 9 = 0
x² - 8x - 57 = 0
To complete the square, we add half the square of the coefficient of x to both sides. so,
x² - 8x - 57 = 0
x² - 8x - 57 + (-8/2)² = 0 + (-8/2)²
x² - 8x - 57 + (-4)² = 0 + (-4)²
x² - 8x + (-4)² - 57 = 0 + (-4)²
(x - 4)² - 57 = 16
(x - 4)² = 16 + 57
(x - 4)² = 73
Taking square roots, we have
x - 4 = ±√73
x - 4 = ±8.544
x = 4 ± 8.544
x = 4 + 8.544 or x = 4 - 8.544
x = 12.544 or -4.544

An urn contains 5 red 6 blue and 8 green balls. if a set of 3 balls is randomly selected, what is the probability that each of the balls will be (a) of the same color? (b) of different colors?
The probability that each of the balls will be; a) P( of the same color) = 0.08875. b) P ( of different color) = 0.247678
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
The Number of red balls = 5
The number of blue balls = 6
The number of green balls = 8
The Total number of balls = 5 + 6 + 8 = 19
Then with three balls selected at random, by using combination method ;
nCr = n!/(n-r)!r!
a) P( of the same color) = 5C3 + 6C3 + 8C3 / 19C3
= 86/969 = 0.08875
b) P ( of different color) = 5C1 X 6C1 X 8C1 /19C3

7 - 0 = 7/5(0 - (-5)) is the equation in slope intercept form for the line passes through points (-5,0) and (0,7).
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope.
We have been asked to write an equation of the line in point-slope form
of a line which passes through (-5,0) and (0,7)
We know that point-slope form = y₂ - y₁ = m(x₂ - x₁)
But first we will find slope(m)
We know that slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
For the pairs of points (-5,0) and (0,7)
⇒ m = [tex]\frac{7- 0}{0 - (-5)}[/tex]
⇒ m = [tex]\frac{7}{5}[/tex]
⇒ m = 7/5
After we substitute the given information we get

The students in a school are all invited to participate in a survey. 48% of the students at the school are males, of whom 16% will participate in the survey. 35% of the females will also participate in the survey. A student is randomly chosen from the school. Find the probability that the student:
a) will participate in the survey
Answer:
If the student is female then the probability that the student will participate is about 67%
If the student is male the probability that they participate is about 33%
Step-by-step explanation:
It is given that 48% of the students in the school are male. That means that the remaining students in this school are (for the sack of this problem) female out 100% of students. You would subtract 48% from 100% which is 52% which is the percentage of students in the school who are female.
From this point you need to find the percentage of students who would participated in the survey. To do that you would divide the number of the type of student who did the survey by the type of student in the school. For example for the male you would divide 16% from 48% or 16 ÷ 48 which would equal to the proposed of males who would participate which is about 33% of males. You would do the same math for finding the probability of females so it would be 35 ÷ 52 which is about 67% of females.
Even though the random student is more likely to be female the chances of the gender of the student is almost 50%/50% because if you round it to the nearest tenth it would be 50.
is the following relation a function?
Answer:
relation
Step-by-step explanation:
To be a function each element from set x has only one unique element in y.
In our case x = 0 has two outcomes y = 1 and y = 3, so is a relation.
f(x) = y
f(-2) = 5
f(0) = 1 and f(0) = 3
f(5) = 8
f(7) = 5
Some memory aids:
Think about if we count how many likes we got on a social media post at the end of the day, then we can not have different numbers for same post yet we can have the same number of likes on different posts to be a function.
f(post 0) = 1 like and f(post 0) = 3 likes ❌ not a function because same post has different numbers of likes at the end of the day -not possible
f(post -2) = 5 likes and f(post 7) = 5 likes ✅ could be a function because different posts can have the same number of likes at the end of the day
