The sign of a will be negative ~
let the value of be be ' -x ' , -x is a negative number (b = -x < 0)
[tex]\qquad \sf \dashrightarrow \: a \times \frac{ - b}{b} [/tex]
[tex]\qquad \sf \dashrightarrow \: a \times \frac{ - ( - x)}{ - x} [/tex]
[tex]\qquad \sf \dashrightarrow \: a \times \frac{ x}{ - x} [/tex]

Therefore, the term a, has a negative sign unless it's value is substituted, I.e -a = 0 ( having no sign )

The probability of an event happening is given as 0.45
What is the probability of the event NOT happening?
Given:
⇒ Probability of happening of an event = 45%
To Find:
⇒ Probability of event
Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.
⇒ Probability of happening event = 45/100
⇒ Probability of happening event = 0.45
⇒ Probability of non happening event = 55/100
⇒ Probability of non happening event = 0.55
Hence, the correct option is (c) 0.45.
Extra Info:
Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

Answer:
$55,200
Step-by-step explanation:
Area of yard = length * breadth
So,
Area = 50*46 = 2300 sq. feet
Again,
Cost per sq. feet = $24
So, For 2300 sq. feet,
Total cost = $24*2300 = $55,200

Which rate does not belong with the other three?Explain
8 pounds for every 2 feet
12 pounds peer 3 feet
20 pounds per 4 feet
24 pounds for every 6 feet
Answer:
The rate "20 pounds per 4 feet", doesn't belong with the other three because you get "5 pounds per foot" for the unit rate and for the other three, you get "4 pound per foot" for the unit rate.
Step-by-step explanation:
Unit rate = How much of something per 1 unit of something else
We write this as a ratio with a denominator of one
In this case, we are using "pound per foot"
1. "8 pounds for every 2 feet"
You can find the unit rate by dividing the first term of the ratio by the second term
[tex]\mathrm{\dfrac{ 8\:pounds }{ 2\:feet }}[/tex]
Simplify
[tex]\mathrm{4\:pounds}[/tex]
Unit rate = 4 pounds per foot
2. "12 pounds per 3 feet"
First, write the rate as a fraction
[tex]\mathrm{\dfrac{ 12\:pounds }{ 3\:feet }}[/tex]
Next, divide the numerator and denominator by 3
[tex]\mathrm{\dfrac{ 12\:pounds \div 3 }{ 3\:feet \div 3 }}[/tex]
Lastly, simplify and turn the denominator equal to 1
[tex]\mathrm{\dfrac{ 4\:pounds }{ 1\:foot }}[/tex]
Unit rate = 4 pounds per foot
3. "20 pounds per 4 feet"
First, write the rate as a fraction
[tex]\mathrm{\dfrac{ 20\:pounds }{ 4\:feet }}[/tex]
Next, divide the numerator and denominator by 4
[tex]\mathrm{\dfrac{ 20\:pounds \div 4 }{ 4\:feet \div 4 }}[/tex]
Lastly, simplify and turn the denominator equal to 1
[tex]\mathrm{\dfrac{ 5\:pounds }{ 1\:foot }}[/tex]
Unit rate = 5 pounds per foot
4. "24 pounds for every 6 feet"
You can find the unit rate by dividing the first term of the ratio by the second term
[tex]\mathrm{\dfrac{ 24\:pounds }{ 6\:feet }}[/tex]
Simplify
[tex]\mathrm{4\:pounds}[/tex]
Unit rate = 4 pounds per foot
The rate that doesn't belong is "20 pounds per 4 feet"
40 points answer ASAP
A manager is assessing the correlation between the number of employees in a plant and the number of products produced monthly. The table shows the data:
Number of employees
(x) 0 10 20 30 40 50 60 70 80
Number of products
(y) 120 200 280 360 440 520 600 680 760
Part A: Is there any correlation between the number of employees in the plant and the number of products produced monthly? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answer: See below
Step-by-step explanation:
a) There is a correlation between the number of employees in the plant and the number of products produced yearly. Specifically, a positive correlation exists because, as we can see on the table, as the number of employees increases, the number of products also increases. And the rate of increase is constant.
b) Let the function be: y = mx + b
When x = 0; y = 120
So:
120 = 0 + c
c = 120
Now the slope:
[tex]\text { Slope }=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{200-120}{10-0}=\frac{80}{10}=8[/tex]
Therefore, the equation that best fits the data is y = 8x + 120
c) The slope in the function represents the constant rate of change, meaning that as the number of employees increases by 1, the number of products produced monthly increases by 20. While the y-intercept of the plot, which is 120, indicates the constant number of products, that is to say, when there are no employees, there are still 120 products.
A pizza with 24 inch diameter cut into 16 pieces whats the area of each slice
Answer:
About 28.27 inches² per slice
Step-by-step explanation:
First, we will find the area of the pizza. Since it is a pizza, we will assume it is a circle and will use the formula for area of a circle.
24-inch diameter / 2 = 12-inch radius
A=πr²
A=π(12)²
A ≈ 452.39 inches²
Now, since the pizza is cut into 16 slices, we will divide the total area by 16.
452.39 inches² / 16 ≈ 28.27 inches² per slice

Ariana started a savings account with $240. She deposits $30 into her account at the end of each month. She wants to know how many months it will take for her account to have a balance greater than $500.
Answer:
9 months
Step-by-step explanation:
$500 - $240 = $260
$260/$30 = 8.67(3s.f.) ≈ 9 months
Recheck:
Balance after 9 months = 240 + (30×9) = 240 + 270 = $510
∴ $510 > $500

And the cross-section perpendicular to the yaxis is a square. Set up a definite integral expressing the volume of the solid
The volume of the cross-section perpendicular to the solid is the amount of space in the cross-section
How to set up the integral?The question is incomplete;
So, I will give a general explanation on how to set up a definite integral for volume of a solid
Assume the solid is a cone;
Using the disk method, the integral of the volume is:

I need help!!!!! The question is in the photo btw
Answer:
114 Feet^2
Step-by-step explanation:
Volume is length*width*height
So we can cut our shape into 2 rectanges.
The bottom one will have the dimensions of 6*1*3 which is 18 feet
And the top one will have the dimensions of 8*4*3 which is 96 feet
Add them up, 96+18=114 feet
find the value of x in the triangle shown below.
x=[]
Answer:
x=[80]
Step-by-step explanation:
angle 1+angle 2+angle x=180
50 +50+x=180
100+x=180
100-100+x=180-100
x=80
Answer:
80
Step-by-step explanation:
The triangle on the image is an isosceles triangle so both of the bottom angles' measure = 50
The sum of interior angles in a triangle is equal to 180
if two angles has 50 degrees then x:
50 + 50 + x = 180
100 + x = 180 subtract 100 from both sides
x = 80
Use the triangle to find each of the six trigonometric functions of _. Show all work
Answer:
you need to find that missing side... so (A squared) x (B squared) = (C squared)
A squared = 5
B squared is missing
C squared = 6
A=25
C=36
36-25= B squared....... B= (square root of 11)
now you need to plug in the numbers for the 6 trig equations...
sin0 = 5/6
cos0 = (square root of 11)/6
tan0 = 5/(square root of 11) which actually equals 5(square root of 11)/11
csc0 = 6/5
sec0= 6/ (square root of 11) which actually equals 6(square root of 11)/11
cot0 = (square root of 11/5

The probability of winning a lottery by selecting the correct six integers from the positive integers not exceeding 50 is _____ × 10–8
The probability of winning a lottery by selecting the correct six integers from the positive integers not exceeding 50 is 6 × 10–8.
What is the probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.
The sample-set S consists of all combinations of 6 distinct elements of the set of 50 elements, and;
[tex]\rm |S| =C(50, 6)=\dfrac{50!}{44!6!}[/tex]
The winning event E ⊆ S is just one winning combination, so that
|E| = 1.
Therefore, the probability of winning a lottery is;
[tex]\rm P(E)=\dfrac{|E|}{|S|}\\\\ P(E)=\dfrac{1}{\dfrac{50!}{44!6!}}\\\\\\ P(E)=\dfrac{44!6!}{50!}\\\\ P(E)= 6 \times 10 {-8}[/tex]
Hence, The probability of winning a lottery by selecting the correct six integers from the positive integers not exceeding 50 is 6 × 10–8.
