Answer:
total cost = $22.4 + $1.12 = $23.52
Step-by-step explanation:
Mr McNeil bought 2 magazines for $7.45 and 1 book for $14.95 . The sales tax is 6% . The total cost of Mr McNeil can be calculated as follows.
He bought 2 magazines for $7.45 .This means the sum of the prize of the 2 magazine he bought is $7.45 and the prize for the single book he bought is $14.95. The total cost of the items he bought excluding the sales tax is the sum of the whole items he bought.
total cost excluding sales tax = $7.45 + 14.95 = $22.4
The sales tax is 5% which can be calculated as follows
5/100 × 22.4 = 112/100 = $1.12
The total cost of Mr McNeil purchase including his sales tax is
total cost = $22.4 + $1.12 = $23.52

Mary walks the 3 day breast cancer walk. They break the 62 miles evenly for each day. How
4
many miles does she walk in one day?
Answer:
she would walk at least those 62 miles
Step-by-step explanation:
We are told that in the 3 days of the walk to fight cancer, Mary breaks the 62 mile barrier every day, that is to say that every day she travels 62 miles or more.
You ask us how much she walks in a single day, considering what the statement that goes at least 62 miles each day says, she would walk at least those 62 miles on a normal day.

Answer:
a) [tex] t_{\alpha}= 1.753[/tex]
b) [tex] t_{\alpha}= -1.383[/tex]
c) [tex] t_{\alpha/2}= \pm 2.179[/tex]
Step-by-step explanation:
Part a
For this case we know that the degrees of freedom are:
[tex] df = 15[/tex]
And we want a right tailed test so then we need to find in the t distribution with degrees of freedom =15 a critical value who accumulate 0.05 of the area in the right and we got:
[tex] t_{\alpha}= 1.753[/tex]
Part b
For this case the significance is [tex]\alpha=0.1[/tex] the degrees of freedom are:
[tex] df = n-1= 10-1=9[/tex]
And since is a left tailed test the critical value for this case would be:
[tex] t_{\alpha}= -1.383[/tex]
Part c
For this case the significance is [tex]\alpha=0.05[/tex] and [tex]\alpha/2=0.025[/tex] the degrees of freedom are:
[tex] df = n-1= 13-1=12[/tex]
And since is a two tailed test the critical values for this case would be:
[tex] t_{\alpha/2}= \pm 2.179[/tex]

Find the balance earned on an account that has $60,000 deposited for 6 years at 1.125% interest compounded continuously? Please help
Answer:
The balance of the account is $64,190.
Step-by-step explanation:
The amount of money after t years of continous compounding is given by the following equation:
[tex]P(t) = P(0)e^{rt}[/tex]
In which P(0) is the initial deposit and r is the interest rate, as a decimal.
$60,000 deposited for 6 years at 1.125% interest compounded continuously.
This means that [tex]P = 60000, r = 0.01125, t = 6[/tex]
So
[tex]P(6) = 60000e^{0.01125*6} = 64190[/tex]
The balance of the account is $64,190.
Rearrange the equation so u is the independent variable.

There are seven black socks, eight blue socks, 10 white socks, and five patterned socks in the drawer. What is the probability of pulling a blue sock, replacing it, and then drawing a patterned sock out of the drawer?
Answer:
2/45
Step-by-step explanation:
Total socks:
7 + 8 + 10 + 5 = 30
P(blue) × P(patterned)
8/30 × 5/30
4/15 × 1/6
2/45
Answer:
2/45
Step-by-step explanation:
The total number of socks is 7+8+10 +5
30
P(blue) = number of blue socks / total
= 8/30 = 4/15
Then we replace it so we have the same number of socks
P(patterned) = number of patterned socks / total
= 5/30 = 1/6
P(blue, replace/patterned) = 4/15*1/6
=2/45
Pip and Sara win some money and share it in the ratio 7:5. Pip gets £30 more than Sara. How much did Sara get?
Answer:
75 sweets.
Step-by-step explanation:
Pip gets 7/(7+5) = 7/12 .
Let Sara get x sweets so Pip gets 7/5 x sweets.
7/5 x = x + 30
2/5 x = 30
x = 5/2 * 30 = 75.
Sara gets 75 sweets.
Answer:
Sara has £75
Step-by-step explanation:
Pip : Sara
7 : 5
If Pip gets £30 more than Sara, then
5x+30=7x
Where x is £?
Subtract 5x from both sides
30=2x
Divide both sides by 2
x=£15
£15

What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, a hiker is told to carry 2 cups of water for every 10 minutes spent walking.
Now, number of cups of water carry for 1 minute
= 2/10
= 0.2 cups
The number of cups of water carry for 60 minutes
= 0.2×60
= 12 cups
Therefore, the number of cups of water the hiker should carry is 12 cups.

If G is the midpoint of

find FG.
Answer:
15
Step-by-step explanation:
15 is the answer because i looked it up
The required value of segment FG is 67 if G is the midpoint of FH.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment FH, where the length of line segment FHrefers to the distance between its endpoints, F and H.
Given that G is the midpoint of FH
FG = 14x + 25 and GH= 73 - 2x,
To determine the value of FG
F______________G______________H
⇒ FH= FG+ GH
Since G is the midpoint of FH, SoFG = GH
⇒ FH = FG+ GH
⇒ FH = 2FG
⇒ FG = GH
Substitute the values of FG = 14x + 25 and GH = 73 - 2x,
⇒ 14x + 25 = 73 - 2x
⇒ 14x + 2x = 73 - 25
⇒ 16x = 48
⇒ x = 48/16
⇒ x = 3
Substitute the value of x = 3 in FG,
⇒ FG = 14x + 25
⇒ FG = 14(3) +25
⇒ FG = 67
Hence, the required value of segment FG is 67 if G is the midpoint of FH.

In a new experimental teaching method, when students have questions in class, they send them to the instructor via a laptop computer. From time to time, the instructor pauses to read the questions and to provide the answers, without revealing the identities of the students who are asking the questions. This new method is supposed to eliminate the reluctance of students to ask questions for fear of revealing their lack of understanding in public. In a study of this new method, 69 male students and 73 female students participated. Treat these as if they were simple random samples. Of the male students, 38 said that they liked the new method better than the traditional one in which students raise their hands to ask questions. Of the female students, only 20 said they liked the new method better
(a) Construct a 95% confidence interval for the difference between the proportions of male and female students who like the new method better. Let p1, denote the proportion of male students who like the new method better and let p2 denote the proportion of female students who like the new method better.
(b) A 95% confidence interval for the difference between the proportions of male and female students who like the new method better is __________.
Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students ([tex]n_m[/tex]) = 69, number who liked the new method (x) = 38
For female students: number of female students ([tex]n_f[/tex]) = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method ([tex]P_1[/tex]) is given as:
[tex]P_1=\frac{38}{69} =0.55[/tex]
The probability that a female student like the new method ([tex]P_2[/tex]) is given as:
[tex]P_2=\frac{20}{73} =0.27[/tex]
c = 95%, α = 1 -c = 0.05
[tex]z_{\frac{\alpha }{2} }=1.96[/tex]
the difference between the proportions of male and female students who like the new method better = [tex]P_1-P_2[/tex] ± [tex]z_{\frac{\alpha }{2} }\sqrt{\frac{P_1(1-P_1)}{n_m} +\frac{P_2(1-P_2)}{n_f}}[/tex] = [tex]0.55-0.27[/tex] ± [tex]1.96\sqrt{\frac{0.55(1-0.55)}{69} +\frac{0.27(1-0.27)}{73}}[/tex] = (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
A crime is committed by one of two suspects, A and B. Initially, there is equal evidence against both of the suspects. After further investigation, it is determined that the guilty party has a blood type found in only 10% of the population at large. Suspect A does have this blood type; the blood type of Suspect B is unknown.
Define the following 3 events A, M and C.
A: "A is guilty" (Thus ° denotes "B is guilty')
M: "A’s blood type matches that of the guilty party"
C: "B's blood type matches that of the guilty party"
A. The police reported that suspect A is not a relative of suspect B. Is it reasonable to set P( MA)=P(C|A)=10%? Why?
B. Assume that P(MAC)=P(C|A)=10%. Given the information from the further investigation of the crime scene, what is the probability that A is the guilty party?
C. Assume that P( MA)=P(C/A)=10%. Given the information from the further investigation of the crime scene, what is the probability that B’s blood type matches that of the guilty party?
Answer:
a) MA conditional with C can be interpreted as A which is known and C which is unknown match
b) 10/11
c) 2/11
Step-by-step explanation:
A={A is the guilty party}
[tex]M_A[/tex] = {A blood type matches that of the guilty party}
C = {B is the guilty party}
[tex]M_C[/tex] = {B blood type matches that of the guilty party}
a) The chance is 10% because MA conditional with C can be interpreted as A which is known and C which is unknown match
b) the probability that A is the guilty party is given by [tex]P(A/M_A)[/tex]. Using bayes theorem:
[tex]P(A/M_A)=\frac{P(M_A/A)P(A)}{P(M_A/A)P(A)+P(M_C/C)P(C)} =\frac{1*1/2}{(1*1/2)+(1/10*1/2)} =\frac{10}{11}[/tex]
c) the probability that B’s blood type matches that of the guilty party is given as [tex]P(M_C/M_A)[/tex]. Using LOTS Therefore:
[tex]P(M_C/M_A)=P(M_C/M_A,A)P(A/M_A)+P(M_C/M_A,A)P(C/M_A)=\frac{1}{10}*\frac{10}{11} +1*\frac{1}{11} =\frac{2}{11}[/tex]
Seemas little sister is now 5 years old.if Her age is 2 years more than 1/4 of seemas age, how old is seems
Answer:
12
Step-by-step explanation:
Seema’s little sister is 2 years more than ¼ of Seema’s age, so you should subtract 2 from 5 to find ¼ of Seema’s age. If 3 is ¼ of Seema’s age, all you do is multiply it by 4 to get the original number. 3x4 is 12, so the final answer is that Seema is 12.

If 15+3x=3(2−2x), then x= [blank]
Answer:
x = -1
Step-by-step explanation:
15+3x=3(2−2x)
Distribute
15+3x = 6 -6x
Add 6x to each side
15+3x+6x = 6-6x+6x
15+9x = 6
Subtract 15 from each side
15-15+9x = 6-15
9x = -9
Divide by 9
9x/9 = -9/9
x = -1

Kelly contracts with Raphael for Raphael to bring a pony to her daughter's birthday party in exchange for $100. Kelly later learns her daughter is frightened of ponies. She contacts Raphael and Raphael agrees to bring a donkey to the party for $50 instead. What is true of the original agreement involving the pony and the $100?
Answer:
It was discharged by substituted contract
Step-by-step explanation:
In this situation, instead of simply canceling their original contract and terminating their interaction, Raphael and Kelly reached another agreement and stablished a substituted contract in place of the original one.
Therefore, the original agreement involving the pony and the $100 was discharged by substituted contract .
