Which table of values could be generated by the equation -10x+5y=15

Answers

9514 1404 393

Answer:

  see below

Step-by-step explanation:

I find it convenient to factor 5 from the equation and re-order the left side:

  y -2x = 3

This makes it relatively easy to see that the values in the left-most table will satisfy this equation.

__

If we look at the table values for x=2, where all the tables differ, we can easily find the one that works:

  1.  7 -2(2) = 3 . . . . this value works in the equation

  2.  0.5 -2(2) = -3.5 . . . . no

  3.  -1 -2(2) = -5 . . . . no

  4.  2.5 -2(2) = -1.5 . . . . no

The winner of a jump rope contest jumped 4 times as long as the person who finished in fifth place. The fifth place finisher jump rope for 120 seconds. Which equation shows the total number of seconds the winner jumped rope?

Answers

Answer:

x= 4*120

Step-by-step explanation:

The 5th place person jumped for 120 seconds

The 1st place jumped 4 times as long

So 120 times 4 = 480 seconds or 8 minutes

Should be 480

4*120= 480

12 x 1/2
How do I solve that, and what’s the answer?

Answers

Answer:

The answer is 6

Step-by-step explanation:

12 divided by 2 is 6. If you have a fraction of 1/2, then its half of it. 6 is half of 12. :)

Answer: 6

Explanation:

You can multiply the numerator by the numerator and the denominator by the denominator.

The numerator of 12 is 12 and denominator of 12 is 1.

[tex]\frac{12}{1} *\frac{1}{2}=\frac{12}{2}[/tex]

Simplify this fraction and you get 6 over 1 or just 6.

You can also use common sense (not really).

You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.

Answers

Answer:

I think B

Step-by-step explanation:

An unconfined compression test was performed to determine the average strength of concrete cylinders (in psi). It is believed that the strength is approximately normally distributed with a standard deviation of 256 psi. A sample of 70 concrete cylinders was taken, and it was found that the average strength was 3000 psi. Find a 91% confidence interval for the true average strength of the concrete.

Be sure to:

• State the value for α.
• State whether you should use z or t and find the appropriate value. Round z-values to 2 decimals. Round t-values to 3 decimals.
• Find the confidence interval (to 2 decimals). State the parameter your confidence interval is for.
• Write a verbal interpretation of your confidence interval.

Answers

Answer:

Explained below.

Step-by-step explanation:

(1)

The confidence level is, 91%.

Compute the value of α as follows:

[tex]\text{Confidence level}\% =(100-\alpha \%)\\\\91% = 100-\alpha \%\\\\\alpha \%=100-91\%\\\\\alpha \%=9\%\\\\\alpha =0.09[/tex]

(2)

As the population standard deviation is provided, i.e. σ = 256 psi, the z value would be appropriate.

The z value for α = 0.09 is,

z = 1.69

(3)

Compute the 91% confidence interval as follows:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

     [tex]=3000\pm 1.69\cdot\frac{256}{\sqrt{70}}\\\\=3000\pm 51.71\\\\=(2942.29, 3057.71)[/tex]

(4)

The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.
