HELP!! I AM GOING TO BE IN DETENTION IF I DON'T GIVE IT ON A FEW DAYS!! I WILL GIVE BRAINLIEST

Answers

Answer 1

Answer:

Let's denote students in D = in the drama club , S = in a sports team

P(D) = 85/330

P(S) = 200/330

P(D and S) = 60/300

P(D or S) = P(D) + P(S) - P(D and S)  = 85/330 + 200/330 - 60/330 = 15/22

P(neither D nor S) = 1- 15/22 = 7/22

The sum of twice a number and 4 times another number is 4. The difference of the numbers is 5. Find the numbers(help a sis out)

Answers

Answer:

1st number = 4

2nd number = -1

Step-by-step explanation:

Let n = 1st number

Let m = 2nd number

2n + 4m = 4

n - m = 5

Substitu method, let n = 5 + m

2(5+m) + 4m = 4

10 + 2m + 4m = 4

6m = -6

m = -1

find n:

n - (-1) = 5

n + 1 = 5

n = 4

What is the measure of angle n?

Answers

Answer:

45 degrees

Step-by-step explanation:

The exterior angles of any polygon is 360 degrees. There are 8 exterior angles, so you have:

8n = 360

divide both sides by 8

n = 45 degrees

Answer: 45

Step-by-step explanation:

Octagon 8 angles

All exterior angles add up to 360 degrees

Meaning we divide

360/8 = 45

Rewrite as a simplified fraction. \large{0.\overline{23} = {?}}0. 23

Answers

Answer:

23/100

Step-by-step explanation:

Given the decimal value 0.23, to write as a fraction;

0.23 = 23/100

The place value of dot will be replaced as 1 at the denominator and since the decimal is in 2 decimal places, two zeros will be added to after the 1 to make it 10 thereby making the required fraction 23/100.  Hence the value of 0.23 as a fraction will be 23/100

what is the slope of -7,2 and -7,4

Answers

Answer:

The slope is undefined

Step-by-step explanation:

We can find the slope using

m = ( y2-y1)/( x2-x1)

    = (4-2)/( -7 -  -7)

    = (4-2)/( -7 +7)

   = 2 / 0

When we divide by 0, the result is undefined

The slope is undefined

Answer:

Undefined

Step-by-step explanation:

Since there is two points we can use (-7,2) and (-7,4) to find the slope

Slope formula for two points:

y2-y1/x2-x1

4-2/-7+7

Which is

2/0

Since 2/0 is not possible the answer will be undefined

Ms. Durand has an obsession with Christmas. She is standing 8ft away from a 20ft Christmas Geometree. She wonders, "hmmm, what is the angle of elevation from myself to the star on the top of the tree?"

Answers

Answer:

68.20°

Step-by-step explanation:

Using Pythagoras rule :

Tanθ = opposite / adjacent

Adjacent = 8ft

Opposite = 20

Tanθ = 20 / 8

θ = tan^-1(20/8)

= 68.198590

Hence, angle of elevation = 68.2°
