Answer: 5x - y = 17
Explanation:
y=5x+b
-3= 5(-4) + b
-3 = -20 + b
17 = b
y = 5x + 17
5x - y = 17

A trip to the Rocky Mountains of Colorado from Denver will take 1 3/4 hours. Assuming we are 1/3 of the way there, how much longer in hours will the trip take?
9514 1404 393
Answer:
1 1/6 hours
Step-by-step explanation:
Assuming distance and time are proportional, 2/3 of the 1 3/4 hours remain:
(2/3)(7/4) = 14/12 = 1 1/6 . . . . hours remain
The trip will take 1 1/6 hours longer.

Answer:
B. the mean is 59 inches
Step-by-step explanation:
if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.
Answer:
B: The mean wingspan is 59 inches.
Step-by-step explanation:
The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.

( 3 × 2 ) + 10 = 16
→ Substitute that answer into f( x )
16² + 5 = 261
a firm wants to select a group of 8 out of its 20 employees to attend a Business trip .in how many ways can this be done if there is a couple who must not be separated
Answer:
Case 1 - 50388 ways when the couple is there in the group of 8 people selected out of 20 employees.
Case 2 - 75582 ways when the couple is not there in the group of 8 people selected out of 20 employees.
Step-by-step explanation:
Given
The couple within the group can not be separated and hence instead of taking total 20 employees , it must be taken as 19 employees.
Now if the couple is there in the selected group of 8 people, then total 7 needs to be selected out of 19 and hence the total number of ways of selecting 7 people out of 19 is
[tex]^7C_{19}[/tex] = 50388
If the couple is not there in the selected group of 8 people, then the total number of ways of selecting 8 people out of 19 is
[tex]^8C_{19}[/tex] = 75582
A study that looked at beverage consumption used sample sizes that were much smaller than previous national surveys. One part of this study compared 20 children who were 7 to 10 years old with 5 who were 11 to 13. The younger children consumed an average of 8.2 oz of sweetened drinks per day while the older ones averaged 14.1 oz. The standard deviations were 10.8 oz and 8.2 oz respectively.
Required:
Do you think that it is reasonable to assume that these data are Normally distributed? Explain why or why not?
Answer:
Step-by-step explanation:
In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model. Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).
The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.
Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.
However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.
Hence, various measures like either goodness of fit or theory testing, would be used for this.

test the continuity of
and evaluate.easy question.show your work.
9514 1404 393
Answer:
(i) not continuous at x=2
(ii) -√2
Step-by-step explanation:
(i) The function simplifies to ((x -2)(x+2))/(x -2) = x +2 . . . . x ≠ 2
The left and right limits at x=2 exist and are the same: 4. However, the function is undefined at x=2, so the conditions for continuity are not met.
__
(ii) The expression is indeterminate (0/0) at x=π/4, so L'Hopital's rule can be used to find the limit.
lim[x→π/4] = ((d/dx)(cos(x)-sin(x)))/((d/dx)(x-π/4)) = (-sin(π/4)-cos(π/4))/1
lim[x→π/4] = -√2/2-√2/2 = -√2
The limit is -√2.

Answer:
$33.75
65%
$13.78
Step-by-step explanation:
commission earned = percentage commission x worth of goods sold
4 1/2% x $750
4.5% x $750
0.045 x $750 = $33.75
Percentage mark-up = [(selling price - cost price) / cost price] x 100
[(90.75 - 55) / 55) x 100
= 65%
new income = 6% of $13 + 13
0.06 x 13 = $0.78
$13 + $0.78 = $13.78

If you paid $5.00 for 10 hamburgers, what was the price for one?
Answer:
0.50 cents
Step-by-step explanation:
If we're going to need the price for 1, we're going to need to divide. So, with the known information, we take 5$ (or 5.00$) and divide it by 10 hamburgers to get your quotient of .50 cents . If I'm wrong, please don't be afraid to correct me. And have a good day stranger!

FinD the 50th term of the sequence defined by the sequence 3n+3????
Answer:
[tex]\huge {\purple {a_{50} = 153}} [/tex]
Step-by-step explanation:
Given sequence is 3n + 3
[tex] \implies a_n = 3n + 3[/tex]
Plug n = 50
[tex] \implies a_{50} = 3(50) + 3[/tex]
[tex] \implies a_{50} = 150 + 3[/tex]
[tex]\huge {\red {\implies a_{50} = 153}} [/tex]
We have ,
=> T_n = a + ( n - 1)d
=> T₅₀ = 3n + 3
=> T₅₀ = 3(50) + 3
=> T₅₀ = 150 + 3
=> T₅₀ = 153

I need to get this question
Answer:
Part A;
- Increases
- Increases
Part B:
- Constant but not 0
- 0
Step-by-step explanation:
Part A:
>> Looking at the speed - time graph of Airplane A, we can see that speed increases from rest at 0 seconds time to time.
>> In graph of airplane B, we can see that distance gradually increases from time at 0 to time at t1. This means that the speed is increasing.
Part B:
>> From time t1 to time t2, we see in airplane A graph that the motion is indicated a horizontal line which means there is constant motion and in constant motion, speed is constant but not zero.
>> In graph of airplane B, we see that the distance between time t1 to time t2 didn't increase. This means that there was no movement. As a result, speed will be 0

Just need help for questions 88 and 90.
A Mustang GT on Missouri has a marked price of $60,000. If paid in cash you are to pay 15% less than the marked price. It also have a hire purchase plan which states to pay 30% of the marked price and $1000 monthly payments for 4 yrs.
A) Discount on Cash price.
B) Cash Price.
C) Amount Payable.
D ) Hire Purchase Price
E ) Difference between the Hire Purchase price and the Cash Price.
Answer:
A) Discount on Cash price. ($9,000 )
B) Cash Price. ($51,000 )
C) Amount Payable. ($51,000 )
D ) Hire Purchase Price ($66,000 )
E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )
Step-by-step explanation:
The following is the workings:
The GT Missouri marked price = $60,000
If paying cash,
Discount = 15%
(15/ 100 ) x $60,000 = $9,000
Actual Price (less discount) = $60,000 - $9000 = $51,000
If hire purchase,
Firstly, 30% marked price,
= (30/100) x $60,000 = $18,000
Monthly payment = $1000
Period = 4 years = 4 x 12 = 48 months
Total monthly payment,
$1000 x 48 = $48, 000
Therefore, total hire purchase payment
Monthly payment + initial 30% payment
= $18,000 + $48,000 = $66,000
Difference between hire purchase and cash price,
= $66,000 - $51,000 = $15,000
