If Simone has 20 bills, then:

1/5 of 20 = 4 [hundreds]
1/4 of 20 = 5 [fifites]
1/10 of 20 = 2 [$20s]

4 * 100 + 5 * 50 + 2 * 20 = 400 + 250 + 40 = 690 [out of $780]
4 + 5 + 2 = 11 [out of 20 bills]

So now we can easily find out she had 9 bills of tens - because 20 - 11 = 9 or because (780 - 690) ÷ 10 = 90 ÷ 10 = 9.

A boat is carried with the current at an angle of 43 degrees to the shore. if the river is approx. 15 meters wide, how far does
mylen [45]

Answer:

22 m

Step-by-step explanation:

The computation of the how much far does the boat travel is as follows:

sin 43 degrees = 15 ÷ d

d = 15 ÷sin 43 degrees

= 15 ÷ 0.6820

= 21.99

= 22 m

Hence, the how much far does the boat travel is 22 m

We simply applied the above formula so that the correct value could come

Determine whether the improper integral converges or diverges, and find the value of each that converges.
____ [38]

Answer:

\int_{-\infty}^0 5 e^{60x} dx = \frac{1}{12}[e^0 -0]= \frac{1}{12}  

Step-by-step explanation:

Assuming this integral:

\int_{-\infty}^0 5 e^{60x} dx

We can do this as the first step:

5 \int_{-\infty}^0 e^{60x} dx

Now we can solve the integral and we got:

5 \frac{e^{60x}}{60} \Big|_{-\infty}^0

\int_{-\infty}^0 5 e^{60x} dx = \frac{e^{60x}}{12}\Big|_{-\infty}^0 = \frac{1}{12} [e^{60*0} -e^{-\infty}]

\int_{-\infty}^0 5 e^{60x} dx = \frac{1}{12}[e^0 -0]= \frac{1}{12}  

So then we see that the integral on this case converges amd the values is 1/12 on this case.

How many solutions does the system of equations have? y=4x-7 and y=4x+2
Alex17521 [72]

Answer:

no solution

Step-by-step explanation:

4x-7=4x+2

-4x +7 -4x +7

0 = 9

0 doesn't equal 9, so there is no solution.

In constructing 98% confidence intervals for means, what do we expect will be true over the long run?
siniylev [52]

In constructing 98% confidence intervals for means, it is true that the statistic is good enough, and is less uncertain.

<h3>What is a confidence interval?</h3>

A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.

Your level of confidence in your findings is shown by the confidence interval. You can never be certain that your results will hold for future surveys or experiments. In statistics, being 95% or 98.5% certain is typically seen as "good enough."
