The values of a and b are 33% and 42.7% respectively.
Calculations and Parameters:Given:
The number of students that like blue uniform is only as 32,
The number of students that like gold uniform is only as 25,
The number of students that like blue and gold uniforms is 12
The number of students that like neither blue nor gold uniform as 6.
Then, the total number of students interviewed are 75 students.
The relative frequency of the students who like blue is 25, therefore,
25/75= 1/3= 0.33
= 33%
The relative frequency of the students that like blue but not gold is 32, therefore,
32/75= 0.427
=42.7%

Gerald would like to add a dental and vision option to the health insurance plan he purchased through his employer. in addition to the 65% of gerald’s $345 monthly health insurance premium, his employer has offered to pay 50% of a $38 monthly dental premium and 75% of a $23 monthly vision premium. if gerald adds both the dental and vision options to his insurance plan, how much will he pay each month towards health insurance? soopergood insurance option monthly premium employer contribution health insurance $345 65% dental $38 50% vision $23 75% a. $141.75 b. $145.50 c. $149.50 d. $260.50
From the calculations, Gerald will now have to pay the sum of $145.50 towards his monthly health insurance.
How is the above sum arrived at?
Note that the first sum being contributed by Gerald is (100%- 65%) of $345. This is 35% of $345 = $120.75
If his employer takes up 50% of $38, this leaves his contribution for dental as 50% of $38 = $19
Also if his employer takes up 75% of $23, his contribtuion for vision premium is 25% of 23 = $5.75
Hence his total contribution is now:
120.75 + 19.00 + 5.75 = $145.50

MacAllisters can make a $79,900 down payment. The total

What is the line of the equation PERPENDICULAR to the slope of -6/5 and through the y-intercept of 3?
Answer:
y = 5/6x+ 3
Step-by-step explanation:
Given
slope = -6/5y-intercept = 3Solving
The slope of the perpendicular line is the negative reciprocal of the original lineSo, the new slope is : -(1/-6/5)) = 5/6It mentions the line passes through the y-intercept of 3y = mx + c⇒ y = 5/6x+ 3What is the completely factored form of f(x) = 6x3 – 13x2 – 4x 15? (x 1)(6x2 – 19x 15) (x 1)2(2x – 3) (x 1)(3x – 2)(5x – 3) (x 1)(2x – 3)(3x – 5)
The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)
How to factor the expression?The expression is given as:
f(x) = 6x³ - 13x² - 4x + 15
Expand the expression
f(x) = 6x³ - 19x² + 6x² + 15x - 19x + 15
Rewrite as:
f(x) = 6x³ + 6x² + 15x- 19x² - 19x + 15
Factorize the equation
f(x) = (x + 1)(6x²- 19x + 15)
Expand (6x² - 19x + 15)
f(x) = (x + 1)(6x² - 10x - 9x + 15)
Factorize the expression
f(x) = (x + 1)(2x - 3)(3x - 5)
Hence, the completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

hope it helps...!!!
Answer:
[tex]6\frac{2}{3}\text{ pounds}[/tex]
Step-by-step explanation:
The baker must have equal amounts in all countainers. Therefore we need to use division to solve this question.
In this scenario we divide the 40 pounds of sugar between the 6 equal containers.Therefore we get:

consuela is displaying a cylindrical case on a pedestal. she wants it to be placed so that there is an even amount of space on either side of the case. if the volume of cylinder shown is 1,130.97 cubic inches, how much space will be on either side if its placed on a pedestal that is 18 inches across? round to the nearest inch
The space that will be on either side if its placed on the pedestal of the cylinder that is 18 inches across will be 4.47 inches.
How to compute the dimension?It should be noted that the volume of a cylinder is given as:
= πr²h
We'll then slot the values given into the formula. This will be:
Volume = πr²h
1130.97 = (3.14 × r² × 18)
1130.97 = 56.52r²
r² = 1130.97/56.52
r² = 20
r = ✓20
r = 4.47

Which piecewise function represents the graph?
Answer:
D
Step-by-step explanation:
If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x > 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.
Hope this helps! :)
