Answer:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

Suppose the population of a certain state is 6,215,000. If 435,050 are children under 5 years of age, 4,972,00 are between the ages of 5 and 65, and 807,950 are over 65, what percentage of people make up each age group?
(A) under 5: ___
(B) between 5 and 65: ___
(C) over 65: ___
Answer:
A) 435,050/6,215,000= 0.07= 7%
B) 4,972,000/6,215,000= 0.8= 80%
C) 6,215,000-(4,972,000+435,050)= 807,950
807,950/6,215,000=0.13=13%
In baseball, the equation E=9R/I a pitcher's earned run average E, where R is the number of earned runs the player allowed and I is the number of innings pitched. Last season, a pitcher had an earned run average of 2.80 and allowed 70 earned runs. How many innings did the pitcher pitch last season?
Answer:
The innings pitched last season is 225.
Step-by-step explanation:
Given that,
Earned run average = 2.80
Allowed earned run = 70
The given equation is
[tex]E=\dfrac{9R}{I}[/tex]
We need to calculate the innings pitched last season
Using given equation
[tex]E=\dfrac{9R}{I}[/tex]
[tex]I=\dfrac{9R}{E}[/tex]
Where, E = earned run
R = allowed earned run
I = innings pitch
Put the value into the formula
[tex]I=\dfrac{9\times70}{2.80}[/tex]
[tex]I=225[/tex]
Hence, The innings pitched last season is 225.

An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.
What is a sample?A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.
Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.
Hence, the correct option is 85,000.

Circle A has center of (4, 6) and a radius of 5, and circle B has a center of (1, 0) and a radius of 15. What steps will hemp show that circle A is similar to circle B?
A. Dilate circle A by a scale factor of 3.
B. Translate circle A using the rule (x - 3, y + 6).
C. Rotate circle A 180 About the center.
D. Reflect circle A over the y-axis.
Answer:
The correct option is;
A Dilate circle A by a scale factor of 3
Step-by-step explanation:
The given parameters are;
The center of circle A is (4, 6)
The radius of circle A = 5
The center of circle B = (1, 0)
The radius of circle B = 15
Therefore, circle A is similar to circle B and is equivalent to circle B, scaled down by a factor of 3
Radius of circle A = 5,
Radius of circle B = 15 = 3 × 5
Therefore, the scale factor for the dilation (transformation) of circle A to circle B is 3.
For a circle to be similar dilate circle A by a scale factor of 3
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
The given parameters are;
The centre of circle A is (4, 6)The radius of circle A = 5The center of circle B = (1, 0)The radius of circle B = 15Therefore, circle A is similar to circle B and is equivalent to circle B, scaled down by a factor of 3
The radius of circle A = 5,
Radius of circle B = 15 = 3 × 5
Therefore, the scale factor for the dilation (transformation) of circle A to circle B is 3.

Mike is buying a box of juice pouches. Flav-O-Squeeze costs $5.88 for 12 pouches. Turbo Taste costs $10.20 for 20 pouches. How much more does Turbo Taste cost per pouch?
Answer:
2 cents
Step-by-step explanation:
you would just divide the Flav-O-Squeeze price by 12 since there are 12 pouches and the Turbo Taste price by 20 since there are 20 pouches and then you would get 1 pack of Flav-O-Squeeze is 49 cents and 1 pack of Turbo Taste is 51 cents and if you subtract them Turbo Taste is 2 cents more then Flav-O-Squeeze
The cost of Turbo Taste per pouch is $0.02.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mike is buying a box of juice pouches. Flav-O-Squeeze costs $5.88 for 12 pouches. Turbo Taste costs $10.20 for 20 pouches.
The more cost will be calculated as,
Cost of Turbo Taste = 10.20 / 20 = $0.51
The cost of Flate-O-Squeeze = 5.88 / 12 = $0.49
The more cost of Turbo-Taste = 0.51 - 0.49
The more cost of Turbo-Taste = $0.02

Find the area of the triangle.
22 m
14 m
Answer:
Area = 154 m²
Step-by-step explanation:
i pressume base = 14 m
height = 22 m
Area of a triangle = 1/2 * base * height
Area = 1/2 * 14 * 22
Area = 154 m²
The area of the triangle is given by the equation A = 154 m²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the area of the triangle be represented as A
Now , the value of A is
Let the height of the triangle be h
The value of h = 22 m
Let the base of the triangle be b
The value of b = 14 m
Now , area of the triangle = ( 1/2 ) x Length x Base
Substituting the values in the equation , we get
Area of the triangle A = ( 1/2 ) x 22 x 14
Area of the triangle A = 154 m²
Therefore , the value of A is 154 m²
Hence , the area of the triangle is 154 m²

Given that (0,-5) is on the graph of f(x), find the
corresponding point for the function
f(-4x).
Answer:
the corresponding point for the function f(x) − 4 is (0,-9)
Step by Step Explanation --
Given that (0, -5) is on the graph of f(x),
WE need to find the corresponding point for the function f(-4x}
f(x) means the output y
f(x)-4 means subtract 4 from the output y
In the given point (0, 5) , x is 0 and y is -5
To get the corresponding point we subtact 4 from y

Find the measure of AB¯¯¯¯¯¯¯¯. A. 14 B. 22 C. 21 D. 20
Answer:
C. 21
Step-by-step explanation:
We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:
BC * AC = DC * EC
Here:
AC = AB + BC = (2x + 5) + 9 = 2x + 14
BC = 9
DC = 10
EC = KC = (1 + 2x) + 10 = 2x + 11
So plug all these in:
BC * AC = DC * EC
9 * (2x + 14) = 10 * (2x + 11)
18x + 126 = 20x + 110
2x = 126 - 110 = 16
x = 8
Put this back into the expression for AB:
AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21
The answer is thus C.

Kyle challenges you to a game. Each player rolls a standard number cube twice. If the sum of the results is divisible by 3, you win. If it is not, Kyle wins. What is your probability of winning? Is this a fair game?
Answer:
The probability of you winning is 1/3
No, it is not a fair game
Step-by-step explanation:
The first thing we need to have here is the sample space. This refers to the set of all possible results that can occur from the rolling.
Please check attachment for this
Kindly note that the total number of possible outcomes is 36.
And in the attachment, sums which are divisible by 3 are circled.
The number of circles we can count is 12
Thus, the probability of you winning would be number of circles/total number of outcomes = 12/36 = 1/3
Is it a fair game?
No, it is not
It can only be a fair game if the probability of winning equals probability of losing ( which is 18/36 = 1/2 or 0.5)
