Which of the following are based on empirical probability
The empirical probability is Life insurance, Car insurance, and Mortality.
What is empirical probability?
The ratio of the number of outcomes in which a defined event occurs to the total number of trials, not in a theoretical sample space but in a real experiment, is the empirical probability, relative frequency, or experimental probability of an event.
Therefore the empirical probability will be Life insurance, Car insurance, and Mortality.

Answer:
y = 1
Step-by-step explanation:
Given:
equation of the parabola: [tex]y=a(x-1)^2+q[/tex]points on the parabola: (-1, -9) and (1, 1)Substitute point (1, 1) into the given equation of the parabola to find q:
[tex]\begin{aligned}\textsf{At}\:(1,1)\implies a(1-1)^2+q &=1\\a(0)^2+q &=1\\q &=1\end{aligned}[/tex]
Substitute the found value of q and point (-1, -9) into the given equation of the parabola to find a:
[tex]\begin{aligned}\textsf{At}\:(-1,-9)\implies a(-1-1)^2+1 &=-9\\a(-2)^2+1 &=-9\\4a+1 &=-9\\4a &=-10\\a &=-\dfrac{5}{2}\end{aligned}[/tex]
Therefore, the equation of the parabola is:
[tex]y=-\dfrac{5}{2}(x-1)^2+1[/tex]
The maximum or minimum point on a parabola is the vertex.
Vertex form of a parabola: [tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex.
Therefore, the vertex of the parabola is (1, 1) and so the maximum value of y = 1
Vertex at (1,q)
There is a point already given from which parabola passes through its (1,1)
So q=1Hence
vertex=(1,1)Equation:-
y=a(x-h)²+ky=a(x-1)²+1Now put (-1,-9)
-9=a(-2)²+1-9=4a+14a=-10a=-5/2a is negative hence parabola is opening downwards
So
vertex is maximum

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.

-n+(-3)+3n+5
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.
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.)

[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

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

Choose the graph that represents the equation y = –|x + 4| + 1.
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.
Why is the graph not facing upwards?
This is because some of the y values are equal to 1 or negative 1, causing the graph to face downwards.
