Answer:

Step-by-step explanation:

P(white) = 24/120

set up a proportion based on these results:

24/120 = x/20

cross-multiply:

120x = 480

x = 4

Solve for x<br> 0.5(5−7x)=8−(4x+6)<br> x = ???

leonid [27]

Hello!

0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1

Your answer is x = -1. I hope this helps!

11. The Leonin family used 90 kWh for their electric consumption for the month of

almond37 [142]

Answer:

The electric bill of the Leonin family was of $ 877,626.

Step-by-step explanation:

Given that the Leonin family used 90 kWh for their electric consumption for the month of August, if the power consumption costs P9.7514 per kWh, to determine how much is their electric bill, the following calculation must be performed:

9.7514 x 90 = X

877.626 = X

Thus, the electric bill of the Leonin family was of $ 877.626.

Which fraction is less than 1 chose all of the correct answer, and explain why you chose and write it down and explain your answ

EleoNora [17]

Answer:

$(3/4)$ and $(2/3)$ .

Step-by-step explanation:

For a fraction of the form $(p / q)$ , the number in front of the division ( $p$ ) is the numerator. The number after the division ( $q$ ) is the denominator.

$\begin{aligned} \frac{p}{q} \quad \genfrac{}{}{0}{}{(\text{numerator})}{(\text{denominator})}\end{aligned}$ .

A positive fraction $(p/q)$ ( $p,\, q > 0$ ) is less than $1$ as long as the numerator $p$ is smaller than the denominator $q$ (that is, $p < q$ .) The reason is that as long as $p,\, q > 0$ :

$\begin{aligned} & \frac{p}{q} < 1 \\ \iff & (q)\, \left(\frac{p}{q}\right) < (q)\, (1) && (\text{given that $q > 0$}) \\ \iff & p < q\end{aligned}$ .

For example, in the fraction $(2/3)$ , $2$ is the numerator while $3$ is the denominator. Both the numerator and the denominator are positive, while the numerator $2\!$ is smaller than the denominator $3\!$ . Therefore, $(2/3)$ would be less than $1$ .

Determine u-x and o-x from the given parameters of the population and the sample.size. round the answer to the nearest thousandt

andriy [413]

The u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 5.

<h3>How to calculate the values?</h3>

From the information given about the population and sample mean, the values include:

u=27 o=5 n=14

The standard deviation will be:

= 5/✓14

= 5/3.74

= 1.34

Therefore, u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 1.34.

4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5

CaHeK987 [17]

ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
$6 {x}^{2} - 6x + 5$

EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.

The highest degree of the polynomial is considered the degree of the polynomial.

For first option,
$4 {x}^{3} - 2x + 10$
the highest degree is 3.

The second option is,
${x}^{2} - 8 {x}^{3} + 3$
This polynomial also has a degree of 3.

The third option is,
$6 {x}^{2} - 6x + 5$
This last option has a degree of 2.

Therefore the correct answer is option C.
