Answer:
Step-by-step explanation:
the probability that the player will not win on Monday or Tuesday, but will win on Wednesday is the same as the probability of winning on the third trial.
This is an example of a geometric probability distribution because trials are repeated until the first success is gotten. Since chance of winning a prize on a given ticket is about 17%, it means that the probability of success, p = 17/100 = 0.17.
Let x represent the number of days before the person wins. The probability that it takes three days before the player wins is expressed as
P(x = 3)
By using the geometric distribution calculator,
P(x = 3) = 0.12
Find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of -1. Show your work for full credit.
Answer:
(-1,-1)
Step-by-step explanation:
x = rcos(theta)
-1 = r cos(-3pi/4)
-1 = r(-sqrt(2)/2)
r = sqrt(2)
y = rsin(theta)
y = sqrt(2)sin(-3pi/4)
y = -1
(-1,-1)

Answer:
radius r = 8 ft
volume V = 2144.66058 ft³
surface area A = 804.247719 ft²
circumference C = 50.2654825 ft
Step-by-step explanation:
Answer:
2 144.7 ft³
Step-by-step explanation:
So the diameter of this sphere is 16ft.
The equation of the volume of a sphere is [tex]\frac{4}{3}[/tex]πr³.
r is the radius which is half of the diameter. So half of 16 is 8.
Now all you have to do is the equation 4 x π x (8)³ divided by 3.
That should equal 2 144.7 ft³

Given a cylinder with a surface area of 2532 cm (squared) and radius of 9 cm, calculate the height of this cylinder to the nearest tenth.
A. 36 cm
B. 282.6 cm
C. 45
D. 10
Answer:
A. 36.4cm = h
Step-by-step explanation:
A=2πrh+2πr² This is the equation to find the surface area of a cylinder
2532 = 2π(9)h + 2π(9)² Multiply
2532 = 18πh + 2π(81) Multiply
2532 = 56.55h + 162π Multiply
2532 = 56.55h + 508.94
-508.94 - 508.94 Subtract 508.94 from both sides
2023.06 = 56.55h Divide both sides by 56.55
36.4cm = h

SOLVE FOR VOLUME
Answer:
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Step-by-step explanation:
the triangle is equilateral triangle ->
a^2 = 14^2 - 7^2 = 147
-> a = 12.124355653
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Answer:
[tex]196meters^2[/tex]
Step-by-step explanation:
The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
To work this out you would first have to work out the area of the triangle. You can do this by multiplying the base of 14 by the height of 14, this gives you 196.
The next step is to divide the answer of 196 by 2, this gives you 98. This is because the formula is the same as that for the area of a square and that a triangle would be half of a square with the same dimensions.
The final step is to multiply 98 by the length of 20, this gives you 1960 meters cubed.
1) Multiply 14 by 14.
[tex]14*14=196[/tex]
2) Divide 196 by 2.
[tex]196/2=98[/tex]
3) Multiply 98 by 20.
[tex]98*20=196meters^2[/tex]

Write an equation of the line that passes through (2, −2) and is parallel to the line y=3x+9.
Step-by-step explanation:
Parallel lines have the same slope, so we know that our line will have a slope of 3 because y = 3x + 9 has a slope of 3. Now, we can use the point-slope formula of the line to find the equation.
We have y - y₁ = m (x - x₁) (m = 3, x₁ = 2, y₁ = -2)
y- (-2) = 3 (x - 2)
y + 2 = 3x - 6
y = 3x - 8
Hope this helps!
Answer:
y = 3x - 8
Step-by-step explanation:
We know that parallel lines have the same gradient. In this situation we want want to work the equation of the line that is parallel to y = 3x + 9 and passes through ( 2 , - 2 ). We know that equations of lines usually go in the format of y = mx + c
↔ Where 'm' is the gradient / slope
↔ Where 'c' is the y - intercept
Using the information in the first sentence we can set up an equation to find the value of 'c'
⇒ Form the equation
→ y = 3x + c
⇒ Substitute ( 2 , -2 ) into the equation to find the value of c
→ -2 = 6 + c
⇒ Minus 6 from both sides to isolate c
→ -8 = c
⇒ Put the value of c back into y = 3x + c
→ y = 3x - 8
So equation of the line that passes through ( 2, −2 ) and is parallel to the line y = 3x + 9 is y = 3x - 8

Answer:
6. B
7. A
8. A
9. A
Step-by-step explanation:
6. As x approaches ∞ (as x goes to the right), y approaches ∞ (y goes up).
7. f(x) = -x⁴ + 5x³ − 2x + 5
The leading coefficient is negative, and the highest power is 4 which is even. So as x→-∞, f(x)→-∞, and as x→∞, f(x)→-∞.
8. The roots are 3, -4, and 1, so the polynomial is:
f(x) = (x − 3) (x − (-4)) (x − 1)
f(x) = (x − 3) (x + 4) (x − 1)
9. The roots are 0 (multiplicity of 1), 1 (multiplicity of 2), and -2 (multiplicity of 2).
f(x) = (x − 0)¹ (x − 1)² (x − (-2))²
f(x) = x (x − 1)² (x + 2)²
The sum of two numbers is no more than 28. Let x represent the first number, and let y represent the second number. Which
inequality represents this situation?
Answer:
Step-by-step explanation:
Let x the 1st and y the 2nd number. So the sum.of x and y means x+y is no more 28. That means is less than 28
So x+y<=28 or x+y<28.

Answer:
5
Step-by-step explanation:
start by putting them in order by value of least to greatest
4, 4, 4, 5, 7, 9, 9
median is the number that is the middle, in this case 5, if there are two middle numbers, you find the average of the two middle numbers.

[tex]2[/tex]×[tex]10^5[/tex] = [tex]200,000[/tex]
Step-by-step explanation:
When working with scientific notation, you are either given a decimal or whole number. The point of scientific notation is to rewrite a number in a more simplified form.You need to change the number so that there is one number on the left side of the decimal. An exponent is used to describe the change in the number. For example:
0.00003
In order to get one number to the left of the decimal, you need to move the decimal to the right 5 spaces. Since the zeros are to the left of the primary number (3), the exponent will be negative. The exponent itself will be the spaces you moved:
[tex]3[/tex]×[tex]10^{-5}[/tex]
The ten is used because of the decimal places you are moving. When you multiply a number by 10, you add a zero. For example:
[tex]2[/tex]×[tex]10^5[/tex]
Since there is a 10, we will be adding in zeros. The exponent determines how many zeros will be added. Since it is a positive number, the numbers will be to the right of the primary number:
200,000

Find the value of x and y. Will mark brainliest.
Answer:
y=3, x=5
Step-by-step explanation:
18=6y, so divide both sides by 6 to get 3=y.
45=9x, so divide both sides by 9 to get x=5.
Answer:
x=5 y =3
Step-by-step explanation:
Opposite interrior angles have the same Number of degrees. So 9x=45. X has to be 5. y = 3 because 3 times 6 is 18. Which is the same number as the opposite vertical side.
