-4/15 = .26 the six is repeated

1.2 - .26 = .95

im not that fam wit dat but here is how u find the x

Step-by-step explanation:

(THIS AND EXAMPLE!!!!)

To evaluate a function, substitute the input (the given number or expression) for the function's variable (place holder, x).

...

Replace the x with the number or expression.

Given the function f (x) = 3x - 5, find f (4). ...

Find the value of h (b) = 3b2 - 2b + 1 when b = -3. ...

Find g (2w) when g (x) = x2 - 2x + 1.

Work Shown:

n = number of questions = 8

p = probability of getting a question correct = 1/2 = 0.5

n*p = number of questions we expect Lee to get correct

n*p = 8*0.5

n*p = 4

We expect Lee gets about 4 questions correct.

4 question that lee guessed would be correct.

There  8 question of true and false.
Lee guessed every question.

Probability can be defined as ratio of favorable outcomes to the sample of events.

Here,
Probability of guessing right answer = 1/2 = 0.5
Probability of lee guessing right answer out of 8 question.
= 0.5 x 8
= 4

Thus, 4 question that lee guessed would be correct.

Answer:

  30 miles

Step-by-step explanation:

The Law of Sines is used for this purpose. The angle at R is the difference ...

  180° -(23° +34°) = 123°

Then the length r satisfies ...

  ST/sin(R) = RT/sin(S)

  ST/sin(123°) = (20 mi)/sin(34°)

  ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi

The length of r or ST is 30 miles.

The equation is already in standard form since standard form is

ax^2+bx+c = 0

Here we have

a = -3

b = 4

c = -2

Mathematical Modeling-

There are four steps to mathematical modeling:

1. Identify the problem and develop a well-defined question.

2.Look for relations and connections between the variables that are involved.

3. Translate features and relationships you have identified into a mathematical model

4. Verify that the mathematical model accurately represents the situation under investigation.

L : H Ratio = 3 : 8  , L as a fraction of H = 3/8

Step-by-step explanation:

Let the no. of Leon's tropical fish be = L

Let the no. of Harry's tropical fish be = H

Given : 2/3 L = 1/4 H

L / H = 1/4 (3/2)

L : H = 3 : 8

Let total fishes or common ratio = x

L = 3/11  (x) , H = 8/11 (x)

Fraction L / H = [ 3/11 (x) ] / [ 8/11 (x) ]

L / H = 3/8
