Answer:

11/6

Step-by-step explanation:

2x/3 = 1/2

Cross multiply, get 4x = 3, x = 3/4

3y/4 = 3/2

Cross multiply, get 6y = 12, y = 2

x + y = 3/4 + 2 = 11/4

xy = 3/4 * 2 = 3/2

(x + y)/(xy) = (11/4)/(3/2) = 11/4 * 2/3 = 22/12 = 11/6

Answer:

The probability is [tex]P(X \le 0.60) = 0.000 [/tex]

Step-by-step explanation:

From the question we are told that

   The overall pass rate is  [tex]R  =  76\% =  0.76[/tex]

   The sample size is  n  =  400

   The percentage that passed is  [tex]k =  60\%  =  0.60[/tex]

Generally the standard error is mathematically represented as

     [tex]\sigma _{\= x } =  \sqrt{\frac{R (1 -R)}{n} }[/tex]    

  =>    [tex]\sigma _{\= x } =  \sqrt{\frac{0.76 (1 -0.76)}{400} }[/tex]

  =>    [tex]\sigma _{\= x } = 0.0214 [/tex]  

Generally the probability of a simple random sample of 400 having a pass rate of 60% or less is mathematically represented as

      [tex]P(X \le 0.60) = P(\frac{X - R}{ \sigma_{\= x}}  \le \frac{0.60 - 0.76}{0.0214} )[/tex]

=>   [tex]P(X \le 0.60) = P(Z \le -7.48 )[/tex]

Generally from the z-table  

      [tex]P(Z \le -7.48 ) =  0.000[/tex]

So

  [tex]P(X \le 0.60) = 0.000 [/tex]

The area of the triangle is the amount of space on it.

The area of the triangle is 85.5 square yard

The given parameters are:

a = 12 yd

b = 16 yd

c = 15 yd

Start by calculating the semi-perimeter (s)

s = 0.5 * (a + b + c)

This gives

s = 0.5 * (12 + 16 + 15)

s = 21.5

The area of the triangle is then calculated as:

[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]

This gives

[tex]A = \sqrt{21.5 * (21.5 - 12) * (21.5 - 16) * (21.5 - 15)[/tex]

Evaluate the product

[tex]A = \sqrt{7301.9375[/tex]

Evaluate the square root

A = 85.5

Hence, the area of the triangle is 85.5 square yard

Answer:

2,870 and 30

Step-by-step explanation:

Answer:

  n² -10 = 6

Step-by-step explanation:

If n represents a positive number, then "the square of a positive number" is represented by n². When that value is decreased by 10, it becomes ...

  n² -10

and if that value is 6, the math expression is ...

  n² -10 = 6

__

Additional comment

Increasing the value by 10 gives ...

  n² = 16

and taking the positive square root gives us the value of the number:

  n = √16 = 4

in this question we have to multiply 4 with 4 then we have to minus 16 with 10 we get the answer 6

= 4 × 4 = 16

= 16 - 10

= 6

Answer:

36 degrees

Step-by-step explanation:

The whole shape is 90 degrees.

90 - 54 = 36

36 degrees

Answer:

36*

Step-by-step explanation:

a right angle is 90* and so you do

90-54=36

meaning your missing angle is 36*

f(x) = 3x − 5 when x=−1, x=0, x=3

Answer:

-8, -2, 4

Step-by-step explanation:

1. Insert -1, 0, and 3 into x

2. Solve

Replace x with -1: f(-1) = 3(-1) − 5

Multiply 3(-1): f(-1) = -3 − 5

Subtract by 5: f(-1) = -8

The answer is -8

Now do this for the rest of the problems:

f(0) = 3(0) − 5 when x=−1, x=0, and x=3

-2 is the 2nd answer

f(3) = 3(3) − 5 when x=−1, x=0, and x=3

4 is the 3rd answer

This is my first answer, so I hope I explained it well!

Remember that i = √(-1), so that

• i ² = -1,

• i ³ = i x i ² = i x (-1) = -i

• i ⁴ = i x i ³ = i x (-i) = -i ² = -(-1) = 1

Multiplying by i again gives i ⁵ = i and the cycle starts over.

The main observation to make here is that raising i to any multiple of 4 returns 1. So,

i ⁴⁸ = (i ⁴)¹² = 1¹² = 1

i ²²³ = i ²²⁰⁺³ = i ²²⁰ x i ³ = (i ⁴)⁵⁵ x i ³ = 1⁵⁵ x (-i) = -i

i ¹¹³ = i ¹¹²⁺¹ = i ¹¹² x i = (i ⁴)²⁸ x i = 1²⁸ x i = i

i ⁸² = i ⁸⁰⁺² = i ⁸⁰ x i ² = (i ⁴)²⁰ x i ² = 1²⁰ x (-1) = -1

i^48 = 1

i^223 = -i

i^113 = i

i^82 = -1

Answer:

x = 67; y = 121; z = 65

Step-by-step explanation:

x + 1 + 112 = 180

x + 113 = 180

x = 67

y - 9 = 112

y = 121

z + 3 + 112 = 180

z + 115 = 180

z = 65

2.) 75

3.) 2

Step-by-step explanation:

120n-150=45n

add 150 to both sides

120n=45n+150

subtract 45n from both sides

75n=150

divide by common number, since 75 is half of 150, use 75.
