Dave buys a baseball for $15 plus an 8% tax. Mel buys a football for $20 plus an 8% tax. What is the difference in the amount Dave and Mel paid, including tax? Round your answer to the nearest cent.
Answer: $5.40
Step-by-step explanation:
First we will find the tax amount for Dave by multiplying 8% by 15.
8% * 15 = 1.2
Now add it to the original price of the baseball which is 15.
15 + 1.2= 16.20 This means Dave paid $16.20 in total.
Now find the tax amount for Mel.
20 * 8% = 1.6
Add 1.6 to the original price which is $20.
1.6 + 20 = 21.60
Mel also paid $21.60 in total.
To find the difference we need to subtract the lowest amount from the highest amount.
21.60 - 16.20 = 5.40

Lisa was throwing a dart at a target. She threw 50 times with her left hand and 50 times with her right hand. The histograms show the distance Lisa missed the target by each time. Make an inference about which hand Lisa has better aim with based on the median of each data set. Justify your response.
Answer:
wow left handed i can't try that i'm very bad at throwing left handed plus he got closer more times then his right wait no she
Step-by-step explanation:
Answer:
The left hand is more accurate.
Step-by-step explanation:
If you look at the graph, it will look like the right hand is more accurate, due to the fact that it has a closer distance than the left. However, the right hand actually never have hit the target while the left did more than once.
What is 2/3 - 5/12 x 9/20 divided by3/4
Answer: 5/12
Step-by-step explanation:
Our common denominator is 60.
25 * 27 = 675
675 / 45 = 15
40 - 15 = 25
Since our denominator is 60, 25/60 is our answer.
25 / 60 simplified is 5 / 12.

Archie is taking a course in probability theory. Discussion sessions with the class TA (teaching assistant) conflict with Archie's trips to the beach. Archie has to decide between attending TA sessions, which might help him do better in the probability course, and going to the beach.
Archie learns that 93% of past students who did not attend TA sessions received a grade of B or below in the course. Archie also learns that 11% of past students received a grade higher than B. After some thought, Archie decides to attend the TA sessions. Not all of his classmates share his decision; in fact, only 4 out of every 18 of his classmates attend discussion sessions with the TA. Compute the probability that Archie will receive a grade higher than a B in the course.
Answer:
The probability that Archie will receive a grade higher than a B in the course is 0.2164.
Step-by-step explanation:
We are given that Archie learns that 93% of past students who did not attend TA sessions received a grade of B or below in the course. Archie also learns that 11% of past students received a grade higher than B.
Let B = event that the student received a grade higher than B.
and T = event that the student discussion sessions with the TA.
So, P(B) = 0.11 and P(T) = [tex]\frac{4}{18}[/tex] = 0.22
Also, the probability that the students who did not attend TA sessions received a grade of B or below in the course = P(B'/T') = P(not B/not T) = 0.92
Now, we have to find the probability that Archie will receive a grade higher than a B in the course given he attended the discussion sessions with the TA = P(B/T)
As we know that the conditional probability formula is given by;
P(B/T) = [tex]\frac{\text{P}(\text{B} \bigcap \text{T})}{\text{P(T)}}[/tex]
Now, as it is given that P(not B/not T) = 0.92
So, [tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{\text{P(not T)}} =0.92[/tex]
[tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{1 - \text{P(T)}} =0.92[/tex]
[tex]\frac{\text{P}(\text{not B} \bigcap \text{not T})}{1 - 0.22}} =0.92[/tex]
[tex]{\text{P}(\text{not B} \bigcap \text{not T})} =0.92\times 0.78[/tex]
[tex]{\text{P}(\text{not B} \bigcap \text{not T})}[/tex] = 0.7176
Also, [tex]{\text{P}(\text{ B} \bigcup \text{ T})}= 1 - {\text{P}(\text{not B} \bigcap \text{not T})}[/tex]
[tex]{\text{P}(\text{ B} \bigcup \text{ T})}[/tex] = 1 - 0.7176 = 0.2824
Now, the formula for [tex]{\text{P}(\text{ B} \bigcup \text{ T})}[/tex] is given by;
[tex]{\text{P}(\text{ B} \bigcup \text{ T})} = \text{P(B)} + \text{P(T)} - {\text{P}(\text{ B} \bigcap \text{ T})}[/tex]
0.2824 = 0.11 + 0.22 - [tex]\text{P(B} \bigcap \text{T})[/tex]
[tex]\text{P(B} \bigcap \text{T})[/tex] = 0.33 - 0.2824 = 0.0476
Now, the required probability P(B/T) = [tex]\frac{\text{P}(\text{B} \bigcap \text{T})}{\text{P(T)}}[/tex]
= [tex]\frac{0.0476}{0.22}[/tex] = 0.2164
Hence, the probability that Archie will receive a grade higher than a B in the course is 0.2164.
How do you these two questions?
Answer:
dy/dx = e⁻²ᵗ (1 − t)
d²y/dx² = -e⁻³ᵗ (3 − 2t)
(1.5, ∞)
Step-by-step explanation:
x = eᵗ
y = te⁻ᵗ
dx/dt = eᵗ
dy/dt = -te⁻ᵗ + e⁻ᵗ
dy/dt = e⁻ᵗ (1 − t)
dy/dx = (dy/dt) / (dx/dt)
dy/dx = e⁻ᵗ (1 − t) / eᵗ
dy/dx = e⁻²ᵗ (1 − t)
d²y/dx² = d(dy/dx)/dt / (dx/dt)
d²y/dx² = (-e⁻²ᵗ − 2(1 − t) e⁻²ᵗ) / eᵗ
d²y/dx² = -e⁻²ᵗ (1 + 2(1 − t)) / eᵗ
d²y/dx² = -e⁻³ᵗ (3 − 2t)
The function is concave up when the second derivative is positive. -e⁻³ᵗ is always negative, so the second derivative is positive when 3 − 2t is negative.
3 − 2t < 0
3 < 2t
t > 3/2
Or, in interval notation, (1.5, ∞).

What were each tax totals. What is the gross pay. What is the net pay. Show your work
Answer:
$440$66, $35.20, $30.80$308Step-by-step explanation:
Gross pay means the amount of money you get without any tax reductions.
40 * 11 = $440
Find the value of all the taxes.
440 * 0.15 = $66
440 * 0.08 = $35.20
440 * 0.07 = $30.80
Net pay means the amount of money you get with tax reductions.
440 - 66 - 35.20 - 30.80 = $308

Write the equation of the line that passes through the points (7,-6) and (0,2). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
[tex]y+6=\frac{-8}{7} (x-7)[/tex]
Step-by-step explanation:
To find the slope of the equation use [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
So, [tex]\frac{-6-2}{7-0}[/tex] = [tex]\frac{-8}{7}[/tex]. Now we can use our slope and any of the two points to write in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex]. Using the point (7,-6), the formula will give [tex]y+6=\frac{-8}{7} (x-7)[/tex].
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.

at a local zoo, adult visitors pay $3 and children visitors pay $1. on one day, the zoo collected a total of $720. if the zoo had 420 visitors that day, how many adults and how many children visited?
Answer:
150 adults and 270 children
Step-by-step explanation:
Let there are x adults and y children.
ATQ,
x+y=420
or
y=420-x ....(1)
Adult visitors pay $3 and children visitors pay $1. on one day, the zoo collected a total of $720.
ATQ,
3x+y=720...(2)
Put equation (1) in equation (2).
3x+420-x=720
2x=720-420
2x=300
⇒x=150
Put the value of x in equation (1)
y=420-150
⇒y=270
So, there are 150 adults and 270 children visited.

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.
Answer:
[tex]x=58[/tex]
Step-by-step explanation:
First, remember that the maximum degree of an angle totals 360°.
Since we already have 294°, this means that what is left must total [tex]360\textdegree - 294\textdegree= 66\textdegree[/tex].
Therefore, this means that our two smaller angles must equal 66°. So:
[tex](36)+(x-28)=66[/tex]
Solve for x. Add on the left:
[tex]x+8=66[/tex]
Subtract 8 from both sides. Therefore, the value of x is:
[tex]x=58[/tex]

The length of a rectangle is (8x – 9) and the width is (2x + 3).
What is the perimeter of the rectangle?
Answer:
P = 20x - 12
Step-by-step explanation:
The Perimeter of a Rectangle is 2l + 2w, where l is the length and w is the width.
Now, let's substitute the given values.
2(8x - 9) + 2(2x + 3)
= 16x - 18 + 4x + 6
= 20x - 12 <--- This is the answer
