To solve the problem we should know about Expressions.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of x in the inequality should be ≥8.

Given to us

  • (0.5x - 0.75) ≥ 3.25

<h3>Solve the inequality,</h3>

(0.5x - 0.75) \geq  3.25\\\\0.5x  \geq  3.25+ 0.75\\\\0.5x\geq 4\\\\x\geq \dfrac{4}{0.5}\\\\x\geq 8

Hence, the value of x in the inequality should be ≥8.

If 10 litres of petrol can cost 650 calculate the cost of 15 Litres and 25 litres​
Cerrena [4.2K]

Answer:

15 liters = 975

25 liters = 1625

Step-by-step explanation:

10 liters = 650

1 liter = 650/10 = 65

15 liters = 65 x 15 = 975

25 liters = 15 liters + 10 liters = 975 + 650 = 1625

The correlation between height and weight among men age 18-74 in the U.S. is about 0.40. Say whether each conclusion below follo
zzz [600]

Answer:

Options a, b, c are correct.

Step-by-step explanation:

First let's see the equation that governs the statement, which is the following:

r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }

Therefore, reading options a, b, c are correct.

Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.

 This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.

 that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.

In which graph does y vary directly as x? It’s not C, I got it wrong.
Ludmilka [50]
Hello there!

Based on my research and information, I really believe that (option a) would actually be your correct answer. I believe this basically because sense the letter k is always constant, we would only divide this by what it is, which is y, and from these, your solution would always look like your (option a). Please inform if correct.

Happy to help!
