what's the correct answers since i got em wrong

​

Answer:

55°

Step-by-step explanation:

In triangle BAC, angle C =

180° - 90° - 70°

Angle C = 20°

In triangle DAB, angle C =

180° - 90° - 55°

Angle C = 35°

Add both angles

20° + 35° = 55°

Answer:

8/35

Step-by-step explanation:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 3 by 5, and get 15.

Then we multiply 1 by 7, and get 7.

Next we give both terms new denominators -- 7 × 5 = 35.

So now our fractions look like this:

15

35

−

7

35

Step 2

Since our denominators match, we can subtract the numerators.

15 − 7 = 8

So the answer is:

8

35

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 8. So we're done reducing.

There you have it! The final answer is:

3/7

−

1/5

=

8/35

Answer:

eight over thirty- five, 8

                                   35

Step-by-step explanation:

In order to subtract the fractions you have to do a simple mathematics step I learned in sixth grade and I still use it now, i'm in ninth grade.

So the tactic I learned in middle school was, keep change flip.

1- Take the  three over the seven: 3                                                                                            

                                                      7  

(Second part of step one)1- Then you do the same to the one and five: 1                                                          

                                                                            5

2- When you subtract a fraction you cannot do it with different denominators. Therefor you have to find the same number in both of the numerator or denominator.(Across from each other)

So multiply the different denominator by each other: 3 x 5= 15

Then you do it with the one and the seven: 1 x 7= 7

Then next you give both the denominators new fractions

     This is what they would look like now

15 - 7

35  35

Since the denominators match now you can subtract the numerators.

4-  15- 7= 8

  So the answer for this step is now 8 over 35.

3- The last step you have to simplify the fraction. The fraction can sometimes be reduced to smaller parts. ( like 1 over 2 was simplified by 2 over 4 and so on and so on) So first you need to divide it by 2, at least try. Since you can't do that you try the next biggest prime number, 3. And you cannot do that so that moves us on to the next prime number, 5 you cannot. There are both the prime numbers, 7 and 11 but that will not work because seven can't do anything but  give you a decimal and 11 is far to greater for the fraction. So you would go  for the prime number in between 7 and 9, 8.

Answer:

The complete question is:

At a university, 13% of students smoke.

a) Calculate the expected number of smokers in a random sample of 100 students from this university:

b) The university gym opens at 9 am on Saturday mornings. One Saturday morning at 8:55 am there are 27 students outside the gym waiting for it to open. Should you use the same approach from part (a) to calculate the expected number of smokers among these 27 students?

Part a is easy, because is a random sample, we can expect that just 13% of these 100 students to be smokers, and 13% of 100 is 13, so we can expect 13 of those 100 students to be smokers.

b) This time we do not have a random sample, our sample is a sample of 15 students who go to the gym in the early morning, so our sample is biased. (And we do not know if this bias is related to smoking or not, and how that relationship is), so we can't use the same approach that we used in the previous part.

Answer:

392.7

Step-by-step explanation:

The volume of the cylinder of radius 5 cm and a height of 5 cm will be equal to 392.7 cubics cm

The volume of the cylinder is the product of the height, pie, and square of the radius.

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

It is given that the radius of the cylinder is 5 cm and the height of the cylinder is 5 cm also.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                  = 3.14 x 5^2 x 5

                                                  = 3.14 x 125

                                                 = 392.7 cubics cm

Thus, The volume of the cylinder of radius 5 cm and a height of 5 cm will be equal to 392.7 cubics cm.

Answer:

c) H0 : p = 5.8%

H1 : p > 5.8%

Step-by-step explanation:

At the null hypothesis, we test that the percentage is equal to a certain value. At the alternate hypothesis, we have a test about this percentage, if it is more, less, or different from the tested value.

A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness

At the null hypothesis, we test if the percentage is 5.8%

[tex]H_0: p = 5.8\%[/tex]

At the alternate hypothesis, we test if this percentage is more than 5.8%. So

[tex]H_a: p > 5.8\%[/tex]

This means that the correct answer is given by option c.

Answer:

A = $2130.49

Step-by-step explanation:

Given the following data;

Time, t = 5 years

Interest rate, r = 8%

Principal = $1450

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 1450(1 + \frac{8}{100})^{5}[/tex]

[tex] A = 1450(1 + 0.08)^{5}[/tex]

[tex] A = 1450(1.08)^{5}[/tex]

[tex] A = 1450 * 1.4693 [/tex]

A = $2130.49

Step-by-step explanation:

For cost $4.23  cost of 1 pound apple = $1.9

For cost $5.9   cost of 1 pound apple = $1.7

For cost $7.61   cost of 1 pound apple = $1.7

For the given mixed fraction,

[tex]2\frac{1}{2}[/tex] pound

The simple faction of  it = 5/2 pound

Now dividing 5 by 2 to get decimal form,

Therefore,

5/2 pound = 2.25 pound

2.25 pound apple cost = $4.23

Hence 1 pound cost = 4.23/2.25

                                  = $1.9

For the given mixed fraction,

[tex]3\frac{1}{2}[/tex]

The simple faction of  it = 7/2

Now dividing 5 by 2 to get decimal form,

Therefore,

7/2 = 3.5

Since, cost of 3.5 pound apple = $5.9

Therefore,

1 pound apple = 5.9/3.5

                        = $1.7

For the given mixed fraction,

[tex]4\frac{1}{2}[/tex]

The simple faction of  it = 9/2

Now dividing 5 by 2 to get decimal form,

Therefore,

9/2 = 4.5

Since, cost of 4.5 pound apple = $7.61

Therefore,

1 pound apple = 7.61/4.5

                        = $1.7
