In this case, A is [tex]\frac{\pi }{3}[/tex] and B is [tex]\frac{\pi }{5}[/tex], so:

  [tex]cos\frac{\pi}{3} cos\frac{\pi}{5} +sin\frac{\pi }{3} sin\frac{\pi }{5} =cos(\frac{\pi}{3} -\frac{\pi}{5} ) = cos\frac{2\pi}{15}[/tex]

Answer:  x = 0.421053y+5.263158

Step-by-step explanation:

x = 0.421053y+5.263158

Answer:

x=0.042105y+10/19

Step-by-step explanation:

Let's solve for x.

19x−0.8y=10

Step 1: Add 0.8y to both sides.

19x−0.8y+0.8y=10+0.8y

19x=0.8y+10

Step 2: Divide both sides by 19.

19x/19=0.8y+10/19

x=0.042105y+10/19

Answer:

1/2

Step-by-step explanation:

I got it wrong then it gave me the right answer of 1/2

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

From the box plot,

Median = $50

Now,

Median = $50

This means,

50% of the clothes are above $50 and 50% of the clothes are below $50.

Now,

The fraction of the sweaters that cost $50 or less is 50%.

So,

= 50/100

= 5/10

= 1/2

Thus,

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

Answer:

The equation a + d(n-1)

Step-by-step explanation:

Where a is the first number in the sequence, d is the common difference and n is the position of a certain number in the series, e.g

1, 2, 3, 4, 5: a = 1, d = 1 (because 2-1=1, 3-2=1, 4-3=1, etc) and n = 1,2,3...

2, 4, 6, 8, 10: a = 2, d = 2 (because 4-2=2, 6-4=2, etc) and n = 1,2,3,4,5...

So for the second sequence, we could try to get the value of n in n = 6 as follows:

a + d(n-1) where a = 2, n = 6 and d = 2

Thus, 2 + 2(6-1) = 2 + 2(5) = 2 + 10 = 12

So the sixth number in the series would be 12

Answer:

1: $3.40     2: $34.00

Step-by-step explanation:

you take 0.34 and multiply it by how many stamps you have. So in this case you have 10 stamps for #1 so you move the decimal over to the right once (since one step is a tenth) and you have $3.40 and for 100 stamps you restart with 0.34 and move the decimal over to the right twice since that would be one-hundredths, and you would get 34. or when you add the units $34.00

Work Shown:

C = 2*pi*r

6.28 = 2*3.14*r

6.28 = 6.28r

6.28r = 6.28

r = (6.28)/(6.28)

r = 1

The radius of the circle is 1 yard.

A = pi*r^2

A = 3.14*1^2

A = 3.14

The area is roughly 3.14 square yards.

The area of the trampoline  is mathematically given as

a = 3.14

Question Parameters:

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference   is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

[tex]a= pi*r^2[/tex]

a = 3.14*1^2

a = 3.14

Answer: 2.44 miles.

Step-by-step explanation:Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Answer:

yes they are

Step-by-step explanation:

(a-b)² = (a-b)×(a-b) = a²-b²

Answer:

No they are not

Step-by-step explanation:

squaring that expression will come out to be a^2-2ab+b^2

this is because you are doing (a-b)(a-b), so you have to multiply each term from the first set of parenthesis by each term in the second set of parenthesis.

a^2-ab-ab+b^2

a^2-2ab+b^2

(a-b)^2≠a^2-b^2

The area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

Area of circle = πr², where radius is r.

Thus, given that a circle has radius (r) = 1 units

Area of the circle = π(1²) = π units²

If the radius is given as r, the area of the circle remains as πr².

Therefore, the area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

Answer: D) The linear model shows a strong fit to the data

The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.

Answer:

40

Step-by-step explanation:

The value of a right angle is 90° and <SQR is a fraction of <PQR.

Hence,  <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.

Or we can do it like this;

⇒ 180-90-50

⇒ 90 - 50

⇒ 40

Thus, Answer is 40.

a. addition property of Equality

Using the z-distribution, as we are working with a proportion, it is found that samples of 937 should be taken.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have that:

Then, we solve for n to find the minimum sample size.

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.675(0.325)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.675(0.325)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.675(0.325)}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.675(0.325)}}{0.03}\right)^2[/tex]

[tex]n = 936.4[/tex]

Rounding up, it is found that samples of 937 should be taken.
