First find the rate, so dollars/1 hour

To do this, divide both sides by 1.5 so u get the Pay of one hour because 1.5/1.5 is one and the result is 16/1 hour, now multiply 16 by the hour so 16(8) then 16(12) and so on, you can do it well! I don’t have a calculator lol

Answer:

a)

\displaystyle\frac{8}{128}

b)

\displaystyle\frac{12}{192}

Step-by-step explanation:

We are given the following information in the question.

Connor earns $24 working every 1.5 hours.

Thus, we can write the ration for hours to dollars earned as:

\text{Ratio} = \displaystyle\frac{\text{Hours}}{\text{Dollars earned}}\\\\= \frac{1.5}{24} = \frac{1}{16}

We have to find the equivalent ratios.

a) Hours = 8. Let x be the dollars earned.

\displaystyle\frac{1}{16} = \frac{8}{x}\\x = 8\times 16\\x = 128

Thus, she earned $128 in 8 hours.

b) Hours = 12. Let x be the dollars earned.

\displaystyle\frac{1}{16} = \frac{12}{x}\\x = 12\times 16\\x = 192

Thus, she earned $192 in 12 hours.

kenny6666 [7]

Answer:

0.34134

Step-by-step explanation:

In other to solve for this question, we would be using the z score formula

z = (x - μ) / σ

x = raw score

μ = mean

σ = Standard deviation

We are told in the question to find the probability that a worker selected at random makes between $350 and $400

let x1 = 350 and x2= 400 with the mean μ = 400 and standard deviation σ = $50.

z1 = (x1 - μ) / σ = (350-400) / 50 = -1

z2 = (x2 - μ) / σ = (400 - 400) / 50 = (0/50) = 0

From tables, P(z <= -1) = 0.15866

P(z <= 0) = 0.5

Then, the probability would give us, P(-1 ≤ z ≤ 0) =0.5 - 0.15866 =

0.34134

Hence, The probability that a worker selected at random makes between $350 and $400 = 0.34134

Louise begins factoring the polynomial, which has four terms.
ad-work [718]

Louise wants to factorize completely the given polynomial 4x^{3}+12x^{2}+5x+15

Grouping first, second terms together and third, fourth terms together

= 4x^{3}+12x^{2}+5x+15

Taking 4x^{2} common from first and second terms of the given expression and taking 5 common from the third and fourth terms.

==4x^{2}(x+3)+5(x+3)

Taking (x+3) common from the given expression,

==(4x^{2}+5)(x+3) is the completely factored form.
