Answer 1

Answer:

65 degrees

Step-by-step explanation:

1) Find the value of x

The sum of all the interior angles of a triangle is always 180 degrees. Knowing this, we can construct the following equation:

[tex](2x-5)+(115-x)+x=180[/tex]

Open up the parentheses

[tex]2x-5+115-x+x=180[/tex]

The two x's cancel out

[tex]2x-5+115=180\\2x+110=180[/tex]

Subtract 110 from both sides

[tex]2x+110-110=180-110\\2x=70[/tex]

Divide both sides by 2

[tex]2x/2=70/2\\x=35[/tex]

Therefore, x is equal to 35.

2) Find the value of <C

[tex]C=2x-5[/tex]

Plug 35 into the equation as x

[tex]C=2(35)-5\\C=70-5\\C=65[/tex]

Therefore, the value of angle C is 65 degrees.

I hope this helps!

she has gotten the following scores so far, what does she need to get on her next test to maintain at
least an 85% average?

85, 78, 92, 84, 93

Answers

Answer:

78%

Step-by-step explanation:

85 × 6 = 510

85 + 78 + 92 + 84 + 93 = 432

510 - 432 = 78

If you randomly select six peanut M&M's, compute that probability that at least one of them is brown.

Answers

Answer(In bold)/Step-by-step explanation:

Compute the probability that a randomly selected peanut M&M is not blue

P (blue) = 23%

P (blue)C = 1 - P(blue) = 100% - 23% = 77%

Compute the probability that a randomly selected peanut M&M is green or red.

P (green) = 15%

P (red) = 12%

P (green or red) = P(green) + P(red) = 27%

Compute the probability that three randomly selected peanut M&M’s are all yellow.

P (yellow) = 15%

(P(yellow))3 = 0.338%

There was replacement in the selection process.  

If you randomly select six peanut M&M’s, compute that probability that none of them are brown.

P(brown) = 12%

P(brown)C = 1 - P(brown) = 100% - 12% = 88%

(P(brown)C)6 = 46.440%

Answer: 30°

Step-by-step explanation:

we have to find the angle adjacent with the right angle. For this we use the (-).

At this point, I am guessing you know how to use SOH-CAH-TOA, for this one we use SOH so sin. If you have a calculator set it on degree mode, then plug it in as sin⁻₁(), we put it like that because the missing angle has the given number opposite and the hypotenuse. It solves it and now we get 30 for the answer. I dont know if that made sense, tell me if it didnt so I can explain it better.

Answer:

  77/85

Step-by-step explanation:

Given:

  cos(A) = 4/5

  sin(B) = 15/17

Find:

  cos(A-B)

Solution:

From your knowledge of Pythagorean triples, you know that one of them is (3, 4, 5) and another is (8, 15, 17). Using your imagination, or by drawing the triangles, you can determine the needed trig functions to be ...

  sin(A) = 3/5

  cos(B) = 8/17

__

Alternatively, you can use the Pythagorean identity to find ...

  sin(A) = √(1 -cos²(A)) = √(1 -(4/5)²) = √(9/25) = 3/5

  cos(B) = √(1 -sin²(B)) = √(1 -(15/17)²) = √(64/289) = 8/17

__

Then application of the angle difference formula is straightforward.

  cos(A -B) = cos(A)cos(B) +sin(A)sin(B)

  cos(A -B) = (4/5)(8/17) +(3/5)(15/17) = (32 +45)/85

  cos(A -B) = 77/85

_____

Some graphing calculators can express the result ...

  cos(arccos(4/5) -arcsin(15/17)) ≈ 0.90588235294

  ... as the fraction 77/85

Answers

Answer:

0.2693

Step-by-step explanation:

Thus is a binomial probability problem :

p = 0.36

1 - p = 0.64

n = 9

x = 3

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 3) = 9C3 * 0.36^3 * 0.64^6

P(x = 3) = 84 * 0.36^3 * 0.64^6

P(x = 3) = 0.2693
