For these questions find the probability of drawing the given cards at random from a standard 52-card deck under each condition: (a) with replacement and (b) without replacement. Write your answers as fractions in simplest form.
2) A club, then a spade
a. With replacement
b. Without replacement
3) An ace, then a queen
a. With replacement
b. Without replacement
Answer:
2
a) 6.37%
b) 6.25%
3
a) 0.60 %
b) 0.59 %
Step-by-step explanation:
2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %
Help me as much as you can please :)
Answer:
Step-by-step explanation:
1). System of equations is,
-2x - y = -22 -------(1)
4x - 8y = 4 -------(2)
By satisfying these equations with the given point (9, 4),
Equation (1)
-2(9) - 4 = -22
-18 - 4 = -22
-22 = -22
True.
Equation (2)
4(9) - 8(4) = 4
36 - 32 = 4
4 = 4
True.
Given point lies on both the equations.
Therefore, the given point is the solution of the system of equations.
2). 3x - 3y = 27 -----(1)
-2x + 9y = -11 ------(2)
Satisfy the equations with the given point (-10, -1)
Equation (1)
3(-10) - 3(-1) = 27
-30 + 3 = 27
-27 = 27
False.
Equation (2)
-2x + 9y = -11
-2(-10) + 9(-1) = -11
20 - 9 = -11
11 = -11
False.
Therefore, the given point is not the solution of the system of equations given.
3. A new restaurant in town is surveying residents to determine how much they typically pay for a meal out. Which of the following best describes a random sample? A. They go door-to-door in a nearby neighborhood. B. They randomly select 50 residents of a local nursing home. C. They call 200 randomly selected town residents. D. They ask patrons if the price was reasonable.
Answer:

A is specific to a single neighborhood
B is specific to a single nursing home
D is specific to only patrons
When looking for a random sample, in this case - the town, you have to consider how to select based on the entire sample.
X + 4 < 6 help.......
Answer:
x<2
Step-by-step explanation:
Hello There!
Our objective for this problem is to isolate the variables
To do so we use inverse operations
x+4<6
subtract 4 from each side
4-4 cancels out
6-4=2
we're left with
x<2
Step-by-step explanation:
It is just like a normal x equation just with an inequality. So for now, just represent the < as and =
so we have x+4=6
subtract 4 from both sides
x+4-4=6-4
x=2
Now we insert the <
x<6
so all values for x are all less than 6
Hope that helps :)
The first is 4 inches wide and 15 inches long. The second is 9 inches wide. Find the length of the second rectangle. A 6.67 inches B 2.4 inches C 41 inches D 33.75 inches
Answer:
D - 33.75
Step-by-step explanation:
If the rectangles are similar, then you can use this cheat:
Width:
9/4 = 2.25
2.25 is the scale factor between the two rectangles.
Using the new-found scale factor, you can do this:
15 x 2.25 = 33.75
This means the length on the second rectangle is 33.75 inches long.

For the end-of-year party, Mt. Rose Middle School ordered a total of 112 pizzas. There were eight fewer veggie pizzas than there were pepperoni pizzas. There were three times as many combo pizzas as pepperoni pizzas. How many pepperoni pizzas were ordered?
HELPPPPP PLSSSSSSSSSS
Answer:
24 Pepperoni pizza
Step-by-step explanation:
v = veggie
p = pepperoni
c = combo
v+p+c=112
p-8 = v
3p=c
substitute both values in equation above, thus,
p-8+p+3p = 112
5p-8=112
5p=120
p=24

One interior angle of a triangle is 30⁰. The other angle measures are x⁰ and y⁰. Which of the following could be the values of x and y? Select ALL that apply
Step-by-step explanation:
One interior angle of a triangle = 30⁰ .
The measure of other two are x and y .
We know that the angle sum property of a triangle is 180⁰ .
=> x + y + 30⁰ = 180⁰
=> x + y = 180⁰ - 30⁰.
=> x + y = 150⁰.
Possible solution set of x and y are ,
(1,149) (2,148 ) ...... (148+2) & (149+1)
Basically we are here decreasing y and increasing x to obtain the values .

I need help with part b and c, I did a already
Answer:
a) V = 35.1 in.^3
b) V = 288 pi in.^3
c) h = 2.7 in.
Step-by-step explanation:
a)
radius of base = 2 in.
height = 8 in.
volume of cone = (1/3)(pi)(r^2)h
V = (1/3)(pi)(2 in.)^2(8 in.)
V = 35.1 in.^3
You are correct.
b)
You must leave the answer in terms of pi, so do not use 3.14 or another approximation for pi.
radius of base = 6 in.
height = 24 in.
volume of cylinder = (pi)(r^2)h
V = (1/3)(pi)(6 in.)^2(24 in.)
V = 288 pi in.^3
c)
volume = 288 pi in.^3
radius = 18 in.
288 pi in.^3 = (1/3)(pi)(18 in)^2 h
288 in. = (1/3)(324)h
288 in. = 108h
h = 2.666 in.
h = 2.7 in.

Answer:
[tex]given \\ heigh(h) = 7m \\ area \: of \: triangle \: (a) = 22m {}^{2} \\ base(b) = x \\ a = \frac{1}{2} \times h \times b \\ \frac{a}{h} = \frac{1}{2} \times b \\ b = 2( \frac{a}{h} ) \\ b = 2( \frac{22m {}^{2} }{7m} ) \\ b = 6.29m \\ base = 6.29m[/tex]
Question 4 ( i-Ready )
The system of equations 2y = 14 - 2x and y = -x + 7 is
graphed. What is the solution to the system of equations?
A. (0,-7)
B. No solution
C. (0,0)
B. Infinitely many solutions
Answer:
Step-by-step explanation:
Note that the two equations are equivalent.
2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.
Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.
David drove 580 km on 7 hour journey. on the city roads he drove 60km/h and on the he drove 100km/h. How long did he drive at each rate?
Answer:
3 hours on the city roads and 4 hours on the other roads
Step-by-step explanation:
580 (total miles driven) - 400 (4 hours of driving 100km/h) = 180 (miles left)
180 (miles left to drive) / 60 (km/h) = 3 (hours driven at the speed of 60km/h)

the triangle was made smaller (i forget what the term is)
it was made smaller by [tex]1\frac{1}{3}[/tex]
to find that you divide 24 by its equivalent side on the other triangle which would be 18
24 / 18 = [tex]1\frac{1}{3}[/tex]
to find what x is equal to you have to find the equivalent side on the other triangle. this would be 16. since the triangle with 16 is bigger the equation is:
16 / [tex]1\frac{1}{3}[/tex] = 12
so x = 12

Find the Area of the Shaded Region. (15 pts)
2 m
7 m
12 m
10 m
Answer:
120 - 14 = 106
Step-by-step explanation:
7 x 2 = 14
10 x 12 = 120 therefore you,
120 - 14 = 106
The area of the shaded region is 106 m².
We have,
The area of the rectangle:
= length x width
From the figure,
Bigger rectangle dimensions:
Length = 12 m
Width = 10 m
Smaller rectangle dimensions:
Length = 7 m
Width = 2 m
Now,
The shaded region.
= Area of the bigger rectangle - Area of the smaller rectangle
= 12 x 10 - 7 x 2
= 120 - 14
= 106
Thus,
The area of the shaded region is 106 m².
