Answer:

x<3

Step-by-step explanation:

-13x>-39

-13x>-39 (Divided by Negative Thirteen)

-13>-13

x<3 (The great sign changes to less than when divided or multiplied by a negative number.)

x={...0,1,2}

Hope this helps ❤

Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year.

lilavasa [31]

Answer:

c. 12.48

Step-by-step explanation:

The earnings per share after t years can be modeled by the following equation:

$E(t) = E(0)(1+r)^{t}$

In which E(0) is the earnings last year and r is the growth rate, as a decimal.

Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year. Growth rate maintained.

This means that $E(0) = 3.50, r = 0.092$

$E(t) = E(0)(1+r)^{t}$

$E(t) = 3.50(1+0.092)^{t}$

$E(t) = 3.50(1.092)^{t}$

If that growth rate were maintained, how many years would it take for Brockman's EPS to triple?

This is t for which E(t) = 3*E(0) = 3*3.50 = 10.50.

$E(t) = 3.50(1.092)^{t}$

$10.50 = 3.50(1.092)^{t}$

$(1.092)^{t} = \frac{10.50}{3.50}$

$(1.092)^{t} = 3$

$\log{(1.092)^{t}} = \log{3}$

$t\log{1.092} = \log{3}$

$t = \frac{\log{3}}{\log{1.092}}$

$t = 12.48$

So the correct answer is:

c. 12.48

A researcher claims that a post-lunch nap decreases the amount of time it takes to run 20 meters. Ten subjects are randomly sele

MakcuM [25]

Answer:

4. A post-lunch nap decreases the amount of time it takes males to sprint 20 meters.

Step-by-step explanation:

This question wants us to state the claim and the hypothesis.

This researchers claim can be found in the first sentence of this question.

Claim: post lunch nap decreases the time it takes to run for 20 meters.

The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.

B. Hypothesis

H0: Ud <= 0

H1: Ud > 0

d = is the race time without a nap - race time with a nap

Help please on this problem

iVinArrow [24]

Answer:

7.5 hours

Step-by-step explanation:

We can model an equation for this problem.

We can write:

$F=mt$

Where

F is the final temperature (15 degrees we need)

m is the rate of temperature change (2 degrees per hour)

and

t is the time, in hours, it will take (we need to find this)

It is given,

F = 15

m = 2

So, t would be:

F = mt

15 = 2t

t = 15/2 = 7.5

So it will take 7.5 hours
