10 months is the answer

Answer:

10 months. Each plan will save 800 dollars.

Step-by-step explanation:

500 + 30x = y

300 + 50x = y

You want the months to give the same amount of money. The x has to be the same for both

500 + 30x = 300 + 50x        Subtract 300 from both sides

500 - 300 + 30x = 50x         Combine

200 + 30x = 50x                   Subtract 30x from both sides

200 = 50x - 30x                    Combine

200 = 20x                              Divide by 20

x = 10

So in 10 months time the amounts will be the same. How much will there be?

500 + 30*10 = 500 + 300 = 800

300 + 50*10 = 300 + 500 = 800

After comparing response times between the audio and picture portions of the MIT test, the t-test resulted in a t-value of 2.97.
Veronika [31]

Answer:

e. reject the null hypothesis the p value is less than 0.05. therefore the difference is significant.

Step-by-step explanation:

given that after comparing response times between the audio and picture portions of the MIT test, the t-test resulted in a t-value of 2.97.

test statistic t = 2.97

Sample size n =250

Critical value of t at 95% is 1.96

We find that test statistic absolute value is greater than 1.96

So p value would be less than 0.05

This implies that null hypothesis stands in the rejected region.

So reject null hypothesis would be correct conclusion.  Sample size cannot be said to be small as more than 30 itself is a good sample size.

e. reject the null hypothesis the p value is less than 0.05. therefore the difference is significant.

Please helppppp pls it's in the screenshot

Answer:

  4. 11/6, 121/36

  5. 5/8, 25/64

  6. 4/7, 16/49

  7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

  perimeter ratio = red leg/blue leg

The area ratio is the square of that:

  area ratio = (perimeter ratio)²

__

<h3>4.</h3>

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

__

<h3>5.</h3>

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

__

<h3>6.</h3>

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

__

<h3>7.</h3>

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81

Express the area of a circle, a, as a function of its circumference, <br> c.
Naddika [18.5K]
Area = PI * radius^2

Circumference = 2 * PI * radius
radius = Circumference / 2 * PI

So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
