Answer:
17/52
Step-by-step explanation:
1/4 of 52 cards are Clubs
4 of 52 are Kings (or 1/13)
P(Clubs OR Kings) = 1/4 + 1/13
= 13/52 + 4/52
= 17/52

Answer:
The median is 45
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
The median is the middle number.
The middle number is expressed as the middle line of the box in a box plot
The middle line hovers over the number 45 which means that the middle number or median is 45
Write a quadratic function h whose zeros are 2 and 7.
First you have to find the factors for these zeros
f(x) = (x-2)(x+8)
Then FOIL to come up with the function
f(x) = x2+8x-2x-16
Combine like terms
f(x) = x2+6x-16
The area of a rectangle is 24x5y7 square yards. If the length of the rectangle is 3x2y6, which expression represents the width of the rectangle in yards?
Answer: [tex]8x^3y[/tex]
Step-by-step explanation:
Given
The area of a rectangle is [tex]24x^5y^7[/tex]
The length of the rectangle is [tex]3x^2y^6[/tex]
The area is given by the product of length and width
Suppose, w is the width of the area
[tex]\therefore A=l\times w\\\Rightarrow 24x^5y^7=3x^2y^6\times w\\\\\Rightarrow w=\dfrac{24x^5y^7}{3x^2y^6}\\\\\Rightarrow w=8x^3y[/tex]
Thus, the width of the rectangle is [tex]8x^3y[/tex]

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that tangents which meet at the same point are equal that is being said
FA=AI=17CH=CG=2.5since [tex]\rm BA=FA+FB[/tex] and it's given that FA and BA are 17 and 29 FB should be
[tex]\rm 29=17+FB[/tex]therefore,
[tex]FB=29-17=\boxed{12}[/tex]once again by two tangent theorem we acquire:
[tex]FB=BH=\boxed{12}[/tex]As BC=BH+CH,BC is
12+2.5[tex]\boxed{14.5}[/tex]likewise,AD=AI+DI so,
21=17+DI [AD=21(given) and AI=17 (by the theorem)]thus,
DI=21-17=[tex]\boxed{4}[/tex]By the theorem we obtain:
DI=DG=4Similarly,DC=DG+CH therefore,
DC=4+2.5=[tex]\boxed{6.5}[/tex]Now finding the Perimeter of ABCD
[tex]P_{\text{ABCD}}=\text{AB+AD+BC+DC}[/tex]substitute what we have and got
[tex]P_{\text{ABCD}}=\text{29+21+14.5+6.5}[/tex]simplify addition:
[tex]P_{\text{ABCD}}=\boxed{71}[/tex]hence,
the Perimeter of ABCD is 71

Which statements about this system of equations are true? Check all that apply. Negative x + 6 y = 16. 8 x minus 6 y = negative 2. The x-variable will be eliminated when adding the system of equations. The y-variable will be eliminated when adding the system of equations. The sum of the system of equations is Negative 8 x = 14. X = 2 y = 3 There is only one solution to the system of equations.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)

Answer:
Step-by-step explanation:
Volume of a pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Area of the rectangular base = Length × Width
= 8 × 6
= 48 mm²
Volume of the pyramid = 192 mm³
192 = [tex]\frac{1}{3}(48)h[/tex]
h = [tex]\frac{192}{16}[/tex]
h = 12 mm
Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.
Height of the box(mm) Yes/No
10 Yes
13 No
8 Yes

Answer:
x = - 6, y = 15
Step-by-step explanation:
3x + 2y = 12
3(-6) + 2(15) = 12
-18 + 30 = 12
----------------------------------------
2x - 3y = -57
2(-6) - 3(15) = -57
-12 - 45 = -57

Find the volume of the cone.
Either enter an exact answer in terms of
π
πpi or use
3.14
πpi and round your final answer to the nearest hundredth.
Answer:
V = 18.84 units³
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(pi)(r²)(h).
Here, with pi = 3.14, r = 3 and h = 2, we get:
V = 18.84 units³
Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous year. Write an exponential function that models the value in dollars of the boat x years after Marcus's purchase.
Answer: [tex]56,900\left( 0.919\right)^x[/tex]
Step-by-step explanation:
Given
Marcos purchased a sailboat for [tex]\$56,900[/tex]
Each year the boat will decrease in value by [tex]8.1\%[/tex]
After 1 year it is
[tex]\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\[/tex]
after another year it becomes
[tex]\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2[/tex]
After [tex]x[/tex] years it is
[tex]\Rightarrow 56,900\left( 1-0.081\right)^x[/tex]
[tex]\Rightarrow 56,900\left( 0.919\right)^x[/tex]

A school needs 5,000 to buy new books for the library. So far the school has raised 75%
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Total money needed= $5,000
Percentage raised= 75%
To calculate the amount collected and the difference required, we need to use the following formulas:
Total collected= 5,000*0.75
Total collected= $3,750
Difference= 5,000 - 3,750
Difference= $1,250

why is this true 9a=11a-2a
Answer:
9a = 11a - 2a
9a = 9a
Step-by-step explanation:
9a = 11a - 2a
11 - 2 = 9
Similarly, 11a - 2a = 9a
Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable a.

If the correlation coefficient is 0.654, what is the explained variation? (give answer as a percent)
Answer:
42.7%
Step-by-step explanation:
Correlation is a statistical measure of inter relationship between two variables' co movement.
Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.
Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.
So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.
