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 in COMPLETE SENTENCES!!
Answers
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.

y=2x -1 ( subtract 1 not negetive) find the slope and thr y intercept
Answers
Answer:
Y intercept: The y intercept is -1, and the slope is 2/1, or 2.
Step-by-step explanation:
In the equation y=mx + b, m is the slope. B is the y intercept. So, by taking y = mx + b, you get y = 2x - 1. So, 2x is the slope, or [tex]\frac{2}{1}[/tex], and -1 is the y intercept.

Sand pouring from a chute forms a conical pile whose height is always equal to the diameter. If the height increases at a constant rate of 5 feet per minute, at what rate is the sand pouring from the chute when the pile is 10 feet high
Answers
Answer:
125π ft³/min
Step-by-step explanation:
Volume of a cone = 1/3πr²h
r is the radius
h is the height.
r = d/2
Volume = 1/3π(d/2)²h
Volume = 1/3π(d²/4)h
Volume = 1/3πd²h/4
Since the diameter is equal to height, hence d = h
V = 1/3πh³/4
V = 1/12πh³
dV/dt = dV/dh × dh/dt
Given
dh/dt = 5ft/min
dV/dh = 3/12πh²
dV/dh = πh²/4
Given h = 10ft
dV/dh = π(10)²/4
dV/dh = 25πft²
Next is to get dV/dt
dV/dt = 25π × 5
dV/dt = 125π ft³/min
Hence the rate at which the sand is pouring from the chute when the pile is 10 feet high is 125π ft³/min

In a building construction project, the on-time completion of the building requires the successive completion of a series of activities. Define E = excavation completed on time; and P[E] = 0.8 F = foundation completed on time; and P[F] = 0.7 S = superstructure completed on time; and P[S] = 0.9 Assume statistical independence among these events.
Answers
Answer:
The probability of the completion of the project on time is 0.504.
Step-by-step explanation:
The question is:
Define the event C : (project completed on time) in terms of E, F and S. Compute the probability P(C) operations will not be on time in terms of E, F and S.
Solution:
The events are:
E = excavation completed on time; P [E] = 0.8
F = foundation completed on time; P [F] = 0.7
S = superstructure completed on time; P [S] = 0.9
The event C denotes the completion of the project on time.
Compute the probability of event C as follows:
P (C) = P (E ∩ F ∩ S)
= P (E) × P (F) × P (S)
= 0.8 × 0.7 × 0.9
= 0.504
Thus, the probability of the completion of the project on time is 0.504.

The value of a truck is $24,000 when it is brand new. The value depreciates $900 per year. when will the value of the car be less than $17,000? write an inequality to represent the situation, do not solve the inequality, defined the variable.
Answers
Answer:
after 8 years
24,000 - 900x < 17,000
the variable is x, the number of years
Step-by-step explanation:
One way is to just subtract 900 from 24000 until it gets to 17000.
1. 23,100
2. 22,200
3. 21,300
4. 20,400
5. 19,500
6. 18,600
7. 17,700
8. 16,800
Another way is to write an inequality.
I know you don't have to solve it, but I'm going to write it anyway.
24,000 - 900x < 17,000
24,000 is the total, or what you start with
900 is what goes down every year
x is the number of years
all of that has to be less than 17,000
To put this into words, it would be: if 24,000 minus $900 times the number of years is less than 17000, what is x?
To find the answer, first find the difference between 24000 and 17000
subtract 2400 from each so so you are left with:
-900x < -7,000
Then to find x, the number of years, divide both sides by -900:
x < 7.777...
since that is the exact answer, and we don't really need that, we can round it up to 8.
x < 8
To learn to do this might be troublesome, but its way faster in the end. I'm not the best at explaining math, but hope this helps :)

The width of a rectangle is 15 inches less than three times it’s length. If the perimeter is 26 inches , what is the area of the rectangle
Answers
Length can be expressed as 2L + 2w = 26 since we know the total perimeter is 26 inches. Width can expressed as w = 3L - 15, since we know that it is 15 inches less than 3x the length. Then substitute the width into the length formula.
2L + 2w = 26
2L + 2(3L - 15) = 26
2L + 6L - 30 = 26
8L = 56
L = 56/8
L = 7 inches
Substitute 7 into the width formula to find width:
w = 3L - 15
w = 3 x 7 - 15
w = 6 inches
Finally use the area formula:
A = L x W
A = 7 x 6
A = 42 [tex]inches^{2}[/tex]

How large a sample must we take if we want the margin of error to be at most 0.01 pound with 95% confidence
Answers
Answer:
The sample size is [tex]n = 153664[/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is E = 0.01
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Let take the standard deviation to be [tex]\sigma = 2 \ pounds[/tex]
Gnerally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ]^2[/tex]
=> [tex]n = [\frac{1.96 *2 }{0.01} ]^2[/tex]
=> [tex]n = 153664[/tex]
College students are a major target for advertisements for credit cards. At a university, 65% of students surveyed said they had opened a new credit card account within the past year. If that percentage is accurate and you survey 100,000 college students in California, how many students would you expect to not have opened a new credit card account
Answers
Answer:
35,000 students did not open a new credit card account
Step-by-step explanation:
If 65% of students surveyed said they opened a new credit card account, the percentage of students that did not open a new credit card account is calculated as follows:
Total percentage = 100%
100% = 65% + (% of students that did not open a new account)
100 - 65 = % of students that did not open a new account
∴ % of students that did not open a new account = 100 - 65 = 35%
Next, let us convert this percentage to actual number
Total number of Students surveyed = 100,000
% of students that did not open a new account = 35%
35% of 100,000
= 35/100 × 100,000
= 0.35 × 100,000 = 35,000

Do you think that students should be proficient in addition before learning multiplication? answer in 175 words! thank you so much :)
Answers
Answer:
Yes, Because if you can't add then you do not know how many times to add the number. For example, 5 x 5= 25
If you don't know what 5+5 equals then how are you supposed to figure out 5+5+5+5+5. That is just common knowledge that you should have learned in your early school years. You need to know how to subtract to divide so it is basically the same concept. I do not know anyone that does not know how to multiply but not add. To me, that does not even seem possible. I know that you have to be really good at adding to multiply too. Cause if you only know how to add up to 100 what happens when you get in high school and college and need to multiply in school over 100? Or thinking higher than that you need to know so that you can do taxes, pay bills, etc... So my answer to this question is yes, you should be proficient in addition to learn multiplication.

4 Minutes
Step-by-step explanation:
If 1/12th of a page is 1/3 of a minute, you have to ask what number do you multiply 1/12th by to equal 1?
12.
So then multiply both 1/12th and 1/3rd by 12. You get 12/12 and 12/3
12/12=1 page
12/3=4 minutes
So every 4 minutes he writes one page.

An automobile manufacturer has four different subcompact cars on the line. Customers selecting one of these cars have a choice of three engine sizes, three body styles, and seven color schemes. How many different selections can a customer make
Answers
Answer:
The customer can make 42 different selections
Step-by-step explanation:
Here, we want to know the different selections a customer can make
A customer can request 1 engine size, 1 body style and 1 colour scheme from the available set for his car
Out of 3 engine sizes , he will select 1; that will be 3 C 1
Out of 3 body styles, he will select 1, that will be 3 C 1
Out of 7 color schemes, he will select one and that is 7 C 1
So the number of different selections will be;
3 C 1 * 3 C 1 * 7 C 1
= 3 * 3 * 7 = 42 different selections
