Answer:
See below ~
Step-by-step explanation:
Let's take an example :
I'm driving a car Z for 1,750 km and it has consumed 70 L of fuel.
===============================================================
Formula for mileage :
Mileage = Distance / Fuel consumed
=============================================================
Solving :
⇒ Mileage = 1,750 km / 70 L
⇒ Mileage = 25 km/L
=============================================================
Understanding by this method :
We can solve for the mileage of a car if we know how much distance it has covered in unit time, and the amount of fuel it has consumed, we can calculate mileage.
Major League Baseball now records information about every pitch thrown in every game of every season. Statistician Jim Albert compiled data about every pitch thrown by 20 starting pitchers during the 2009 MLB season. The data set included the type of pitch thrown (curveball, changeup, slider, etc.) as well as the speed of the ball as it left the pitcher’s hand. A histogram of speeds for all 30,740 four-seam fastballs thrown by these pitchers during the 2009 season is shown below, from which we can see that the speeds of these fastballs follow a Normal model with mean μ = 92.12 mph and a standard deviation of σ = 2.43 mph.
Compute the z-score of pitch with speed 95.8 mph. (Round your answer to two decimal places.)
Approximately what fraction of these four-seam fastballs would you expect to have speeds between 91 mph and 93.2 mph? (Express your answer as a decimal, not a percent, and round to three decimal places.)
Approximately what fraction of these four-seam fastballs would you expect to have speeds below 91 mph? (Express your answer as a decimal, not a percent, and round to three decimal places.)
A baseball fan wishes to identify the four-seam fastballs among the fastest 20% of all such pitches. Above what speed must a four-seam fastball be in order to be included in the fastest 20%? (Round your answer to the nearest 0.1 mph.)

Answer: 4
Step-by-step explanation:
First, we will find the length of sides TU and T'U' to compare. Then, we will find the scale factor. Since the shape gets bigger and not smaller, we will have a whole number - not a fraction.
TU = 3 units
T'U' = 12 units

What are the quotient and remainder of (3x4 - 2x + 7x-4)= (x - 3)?

b. 3x + 77? + 21x + 70; -206
d. 37° +73+ + 21x + 703 76
The quotient of dividing (3x⁴ - 2x³ + 7x² - 4) by (x - 3) is 3x³ + 7x² + 28x + 84 and the remainder is 248
How to determine the quotient and the remainder?The division expression is given as:
(3x⁴ - 2x³ + 7x² - 4) / (x - 3)
Set the divisor to 0
x - 3 = 0
Solve for x
x = 3
Substitute x = 3 in 3x⁴ - 2x³ + 7x² - 4
3x⁴ - 2x³ + 7x² - 4 = 3(3)⁴ - 2(3)³ + 7(3)² - 4
Evaluate
3x⁴ - 2x³ + 7x² - 4 = 248
This means that the remainder is 248
Recall that:
Dividend = Divisor * Quotient + Remainder
So, we have:
3x⁴ - 2x³ + 7x² - 4 = x - 3 * Q + 248
Subtract 248 from both sides
3x⁴ - 2x³ + 7x² - 252 = x - 3 * Q
Divide both sides by x - 3
Q = (3x⁴ - 2x³ + 7x² - 252)/(x - 3)
Factorize the numerator
Q = (x - 3)(3x³ + 7x² + 28x + 84)/(x - 3)
Cancel out the common factors
Q = 3x³ + 7x² + 28x + 84
Hence, the quotient is 3x³ + 7x² + 28x + 84 and the remainder is 248

Answer:
4568 ft³
Step-by-step explanation:
You want the volume of the figure made from two rectangular prisms.
VolumeThe volume of the whole is the sum of the volumes of its parts. The volume of a rectangular prism is the product of its dimensions.
The horizontal prism is 7 ft high, 8 ft wide, and 45 ft long.
The vertical prism has a square base 8 ft on a side, and is 32 ft long.
The total volume is ...
V = horizontal volume + vertical volume
V = (7 ft)(8 ft)(45 ft) + (8 ft)²(32 ft) = 4568 ft³
The volume of the figure is 4568 ft³.
<95141404393>
The total volume of the figure is 4,568 ft³
How to find the volume?We can view this as two different rectangular prisms, remember that the volume of a rectangular prism is equal to the product between its dimensions.
For the one that is laid down, the volume is:
V = 7 ft*8 ft*45 ft
V = 2,520 ft³
For the other prism, the volume will be:
V' = 8ft*8ft*32ft = 2,048 ft³
Adding the two volumes we will get:
volume = 2,520 ft³ + 2,048 ft³ = 4,568 ft³
That is the total volume of the figure in cubic feet.

What is the value of x?
We have been given the two lengths as x and y So, the value of x would be equal to root 80.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly canceled from both the numerator and the denominator.
Thus, a = px, b = qx
we have been given the two lengths as x and y.
From the figure, we know that
11: y = y: 5
Express in fraction
11/y = y / 5
y^2 = 5(11)
y ^2 = 55
So, y = √55
From Pythagoras theorem;
[tex]x^{2} =5^{2} +y^{2} \\\\x^{2} =5^{2} +55 \\\\x^{2} =25 + 55\\\\x^{2} =80\\\\x = \sqrt{80}[/tex]

please help me with this
Answer:
2n + 2
Step-by-step explanation:
If the directions for this problem say to "Simplify" then what you will do is to combine like terms. This is an expression because there is no equal sign. If it had an equal sign (and more information) it could be solved.
Since it only an expression we simplify:
-n + (-3) + 3n + 5
= -n + 3n + (-3) + 5
= 2n + 2
Answer:
I believe that it is, 2n + 2.
Step-by-step explanation:
You add all the common factors ( sorry if its a wrong vocab word ) -
( {-3} + 5 ) and ( 3n + { -n } )
-3 + 5 would also be 5 - 3 = 2
3n + -n would be 3n - n = 2n so it would be,
2n + 2 or 2 + 2n.

Answer:
It's the last choice.
Step-by-step explanation:
It has a V shape because of the absolute value lines | |
But it is an inverted V because of the leading negative.
The vertex is at y = 1 because of the + 1.
The + 4 moves the whole graph 4 units to the left of the origin.
So the vertex is at (-4, 1)
Answer:
The correct option is graph D. because the equation has all negative x values, meaning this graph will be to the left.

2 x - 12 = - 35
2x=-35+12
2x = - 23
