Answer: Fourth Choice. 1.4

Step-by-step explanation:

<u>Concept:</u>

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

<u>Solve:</u>

Given

(x² - 4) / 3x

x = 5

Substitute the value of x

[(5)² - 4) / 3(5)

Simplify exponents

(25 - 4) / 3(5)

Simplify numerator with subtraction and denominator with multiplication

21 / 15

Simplify by division

7/5 = 1.4

Hope this helps!! :)

Please let me know if you have any questions

Write the equation for each line. (will give brainlest)
poizon [28]

Answer:

y = \frac{2}{3}x + 1

Step-by-step explanation:

The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 3) and (0, 1).

Slope = \frac{3-1}{3-0}

         = \frac{2}{3}

Thus, the slope of the line is \frac{2}{3} .

Based on the graph, the y-intercept is 1.

Thus, the equation of the line is: y = \frac{2}{3}x + 1.

The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $8 each and will sell 900
andrew-mc [135]

Step-by-step explanation:

the probability that the ticket will win you 600 dollars * 1/1500 = 600/1500.

the probability that the ticket will win you 50 dollars is 50 * 5/1500 = 250/1500.

the probability that the ticket will win you 25 dollars is 25 * 20/1500 = 500/1500.

your expected value is -1 + 600/1500 + 250/1500 + 500/1500 = -.1.

the average loss for each dollar that is bet is equal to 10 cents.

hope this helped

If the nth term of a sequence is n^2 -3, find the first 3 terms and the 10th term.
Pepsi [2]

Answer: -2, 1, 6,...97

Step-by-step explanation:

1st term: 1^2 - 3 = -2

1^2 = 1

1-3=-2

2nd term: 2^2-3 = 1

2^2 = 4

4-3=1

3rd term: 3^2-3 = 6

3^2 = 9

9 -3 = 6

10th term: 10^2-3 = 97

10^2 = 100

100-3=97
