Answer:
[tex]\dfrac{1}{4}[/tex]
Step-by-step explanation:
Total number of cards in a standard deck = 52
Number of hearts in the deck = 13
Number of clubs in the deck = 13
Number of diamonds in the deck = 13
Number of spades in the deck = 13
Four cards are drawn at random by Timothy.
These four cards are drawn from each one of the suits.
And the cards are not replaced.
Therefore, now cards remaining in each suit:
Remaining number of hearts in the deck = 12
Remaining number of clubs in the deck = 12
Remaining number of diamonds in the deck = 12
Remaining number of spades in the deck = 12
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases are 12 (i.e. number of hearts)
Total number of cases = 12 [tex]\times[/tex] 4 = 48
Therefore, the required probability is:
[tex]\dfrac{12}{48} = \bold{\dfrac{1}4}[/tex]

For f (x), evaluate the following:
a, f(0)
b. f(6)
Show all of your work
Answer:
a). f(0) = 4
b). f(6) = 8
Step-by-step explanation:
a). When x < 5, piecewise function to be considered,
f(x) = x + 4
Since, x = 0 is less than x = 5
f(0) = 0 + 4
f(0) = 4
b). When 5 ≤ x < 7,
Piecewise function to be considered,
f(x) = 8
Therefore, for x = 6,
f(6) = 8
if a jigsaw puzzle is priced 17.00 but cost 17.68 at the register what is sales tax rate
Answer:
4%
Step-by-step explanation:
17.68 / 17 = 1.04
1.04 - 1 = 0.04
0.04 = 4%
So the sales tax rate is 4%
A cell phone company charges $40 plus .05 per text. What is the slope?
The slope will be 0.05.
What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a cell phone company charges $40 plus 0.05 per text
We can write the general equation for the cell phone as -
y = 0.05x + 40
Now, we can compare with the general equation of line as -
m = 0.05
Therefore, the slope will be 0.05.

6(2x- 5)= 15x+3
Answer:
x = -11Step-by-step explanation:
6(2x- 5)= 15x+3 expand

12x - 15x = 30 + 3 simplify
-3x = 33 divide -3 both sides
x = 33 / -3 simplify

Xavier can swim at a constant speed of 5/3 meters/second. He is trying to qualify for the N ational Swim Meet. To qualify, he must complete a 100-meter race in 55 seconds. Will Xavier be able to qualify? Why or why not?
Answer:
Xavier will not be able to qualify because the speed required for him to qualify is greater than the speed at which he runs
Step-by-step explanation:
Here, we want to know if Xavier will be able to qualify or not
His constant speed is 5/3 m/s
Now to win , he needs a speed of 100 m/55 sec = 20/11 m/s
So now, we need to know the bigger fraction between the two
Mathematically, that will be
5/3 - 20/11 = (55-60)/11 = -5/11
As we can see, the required speed is greater than what he can run
So this means that he will not be able to qualify
(From MATH workbook 8A)
Answer:
x = 0.5
Step-by-step explanation:
Given
- 8.25x + 12 - 1.75x = 10.5x + 1.75 , that is
- 10x + 12 = 10.5x + 1.75 ( subtract 10.5x from both sides )
- 20.5x + 12 = 1.75 ( subtract 12 from both sides )
- 20.5x = - 10.25 ( divide both sides by - 20.5 )
x = 0.5

Answer:
122.5 People
Step-by-step explanation:
4500-90 = 4410
4410 divided by 36 equals 122.5
==========================================================
Explanation:
n = number of people invited
n+2 = total number of people after adding Oscar and Julie
36(n+2) = total cost before the $90 fee
36(n+2)+90 = total cost after the $90 fee
Set that equal to the budget of 4500 and isolate n
36(n+2)+90 = 4500
36n+72+90 = 4500
36n+162 = 4500
36n = 4500-162
36n = 4338
n = 120.5
n = 120
We round down so that we don't go over budget
Oscar and Julie can invite 120 people.
-----------
Check:
If n = 120 then 36(n+2)+90 = 36(120+2)+90 = 4482 which is under budget
If n = 121 then 36(n+2)+90 = 36(121+2)+90 = 4518 which is over budget
This confirms that 120 is the answer.

Describe the graph of y > mx, where m > 0?
Answer:
The graph of y > mx, where m > 0, consists of a dashed line and a shaded half-plane. The line has a positive slope and passes through the origin. The shadow of the half plane is above the line. m<0 means slope is negative
b>0 means the line will intersect the y axis above 0. Since the slope is positive, the graph is increasing. So like stated above The boundary line is dashed, and everything above it is shaded.

Drag each tile to the correct box. Not all tiles will be used. Consider function f.
Answer:
Steps in order will be
[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]
Step-by-step explanation:
Consider the function [tex]f(x)=\sqrt{7x-21}[/tex]
We need to find [tex]f^{-1}(x)[/tex]
For finding [tex]f^{-1}(x)[/tex] replace f(x) with y
Step 1: Replace f(x) with y
[tex]y=\sqrt{7x-21}[/tex]
Now, solve for x
Step 2: Taking square on left side
[tex]y^2=(\sqrt{7x-21})^2\\y^2=7x-21[/tex]
Step 3 : take 7 common
[tex]y^2=7(x-3)[/tex]
Step 4 : Divide both sides by 7
[tex]\frac{y^2}{7}=x-3[/tex]
Step 5: Add 3 on both sides
[tex]\frac{y^2}{7}+3=x-3+3\\x=\frac{y^2}{7}+3[/tex]
Step 6: Replace x with y and x with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x)=\frac{1}{7}x^2+3[/tex] where x≥0
Steps in order will be
[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]

Use the definition of continuity to determine whether the function f(x) graphed
below is continuous at x = 0.
The function graphed below is not continuous.
On the graph at x = 0, the function is not continuous. There is a jump on the graph at x = 0.
A function is said to be continuous if the graph of the function has no break, hole or asymptotes.
In this graph it is clear that the graph is not continuous because the function approaches -4 until when x = 0 and then after x = 0, function takes the values from 1.
This causes a jump on the graph of the function which gives a discontinuity at x = 0.
