Kara Danvers (Supergirl) has always relied on her strength to win fights. But what happens when she meets an alien just as strong? Her sister is training her to be a more technical fighter so that Supergirl can meet any challenge. The data below record the significant strikes during randomly selected training sessions 6 months apart. Is Kara showing improvement in her fighting?

Strikes (pre): 29 32 44 34 19

Strikes (post): 51 45 68 92 64


Write the Hypotheses:

H_0:_______________, the mean difference in ___________ between ____________ and ______________ is _______________

H_a:_______________, the mean difference in ___________ between ____________ and ______________ is _______________

Answers

Answer:

H0 : The mean difference in strikes between pre and post strike is equal to 0

H1 : The mean difference in strikes between pre and post strike is not equal to 0

Step-by-step explanation:

The scenario described abibe meets the condition for a paired (dependent) sample t test as the same subject is involved in both the pre and post strike data. Therefore measurement from the strike(pre) must be paired with measurement from the strike(post) data.

For a paired test involving a single subject ; The mean difference in the two sample is 0 ; that is both are the same while the alternative negates the null by claiming that the mean difference is not equal to zero.

Calculate the mean of the data set {62, 75, 85, 63,69, 72, 76, 84, 87,88} round to the nearest tenth ?

Answers

Answer:

total scores is 10 then divde 761 by the total number of scores which is 10

c.The APR is not a good way to compare loans.
d.The APR helps compare loans with the same payback period, but with different monthly rates and different fees.

Answers

Answer:

d. The APR helps compare loans with the same payback period, but with different monthly rates and different fees.

Step-by-step explanation:

A loan can be defined as an amount of money that is being borrowed from a lender and it is expected to be paid back at an agreed date with interest.

Generally, the financial institution such as a bank lending out the sum of money usually requires that borrower provides a collateral which would be taken over in the event that the borrower defaults (fails) in the repayment of the loan.

An annual percentage rate (APR) is an amount of money paid as interest by borrowers or earned on loans by lenders such as banks, expressed as a percentage of the amount borrowed or invested over a 12-month period i.e on an annual basis.

Generally, the annual percentage rate (APR) helps compare loans with the same payback period, but with different monthly rates and different fees.

The measure of two supplementary angles are A=(4a+7)° and B=(a-2)° find the measure of the two angles

Answers

Answer:

147˚, 33˚

Step-by-step explanation:

supplementary angles means those angles add up to 180˚

so A+B = 180

substitute A and B with the values given.

(4a+7) + (a-2) = 180

combine like terms

5a + 5 = 180

5a = 175

a = 35

Now that we have a, substitute in the actual value of a into the expressions for each angle.

for <A: 4(35) + 7 = 147˚

for <B: 35 - 2 = 33˚

Answer:

<A =147

<B =  33

Step-by-step explanation:

Supplementary angles add to 180

4a+7 + a-2 = 180

5a+5 = 180

5a+5-5 = 180-5

5a = 175

Divide by 5

5a/5 = 175/5

a = 35

<A = 4a+7 = 4*35 +7 = 140+7=147

<B = a-2 = 35-2 = 33

There are 50pupils in a class .Out of this number 1/10 speak French only and 4/5 of the reminder speak both French and English.lf the rest speak English only,find the number of student who speak
a.both French are English
b.only English

Answers

Answer:

40 pupils speak French and English

5 pupils speak only English

Step-by-step explanation:

**The grammar has some errors, but I hope I understood it correctly to answer your question correctly!**

Here's what we know about the question:

- 1/10 of the 50 pupils speak only FRENCH

- 4/5 of the 50 pupils speak FRENCH and ENGLISH

- rest of the pupils speak only ENGLISH

Here's what we're trying to find:

- # of pupils that speaks FRENCH and ENGLISH

- # of pupils that speak only ENGLISH

Let's start of with find how many pupils speak French:

1/10 of the 50 pupils speak French. To find the # of pupils, divide 50 by 10:

50/10 = 5

5 pupils speak only French

Now let's find out how many pupils speak French and English:

4/5 of the 50 pupils speak French and English. We are going to divide 50 by 5 and then multiply the result by 4:

50/5 = 10

10 * 4 = 40

40 pupils speak French and English

Finally, let's find the number of pupils that speak only English:

The question only says that the rest of the 50 pupils speak only English.

We are going to add the other pupils who don't speak only English, then subtract that value from 50:

40 + 5 = 45

50 - 45 = 5

5 pupils speak only English

eric has a summer lawn mowing buisness. based on experience eric knows that p= -3x^2 + 150x -1200 models his profit, p, in dollars, where x is the amount he charges per lawn. how much does he need to charge if he wants to break even? show your work

Answers

Answer:

Eric can either charge $10 or $40 in order to break even.

Step-by-step explanation:

Eric has a summer lawn mowing business and the equation:

[tex]p=-3x^2+150x-1200[/tex]

Models his total profit p by charging x dollars per lawn.

We want to determine what price Eric needs to charge in order to break even.

The price Eric charges to break even means that his total profit will be zero. Hence, we can let p = 0 and solve for x. Thu:

[tex]0=-3x^2+150x-1200[/tex]

We can divide both sides by -3:

[tex]0=x^2-50x+400[/tex]

Factor:

[tex]0=(x-10)(x-40)[/tex]

Zero Product Property:

[tex]x-10=0\text{ or } x-40=0[/tex]

Solve for each case. Hence:

[tex]x=10\text{ or } x=40[/tex]

Therefore, Eric can either charge $10 or $40 in order to break even.

Step-by-step explanation:

Juan, Pedro and Luis build a 60 meter long wall. Juan builds triple the size of Pedro and Luis double the size of Juan. How many meters did each one build?

Total length of the wall is 60 m.

Let Pedro make p length of the wall.

Juan make = 3 p

Luis make = 6 p

So,

According to the question

60 = p + 3 p + 6 p

60 = 10 p

p = 6

So, Pedro make 6 m of wall, Juan make 18 m of the wall and Luis make 36 m of the wall.
