Answer: The ice image, bottom left.

Step-by-step explanation:

The albedo values give information about the proportion of radiation that a given object surfaces, for example, if an object has an albedo value of 0.2, this means that the object reflects 0.2*100% = 20% of the radiation.

You usually can see that darker objects have a smaller albedo value, while clearer objects have a bigger albedo value, meaning that as clearer is the color, usually it reflects a bigger proportion of the radiation.

Here we have that the bigger albedo value is in the ice ( 0.55), so the correct image is the ice image, at the bottom left.

Answer:

The value of the test statistic is of 0.22.

Step-by-step explanation:

Our test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the expected mean, $\sigma$ is the standard deviation(square root of the variance) and n is the size of the sample.

A lumber company is making boards that are 2920.0 millimeters tall.

This means that $\mu = 2920$ .

A sample of 12 is made, and it is found that they have a mean of 2922.7 millimeters with a variance of 121.00.

This means that $X = 2922.7, n = 12, \sigma = \sqrt{121} = 11$ . So

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$t = \frac{2922.7 - 2922}{\frac{11}{\sqrt{12}}}$

$t = 0.22$

The value of the test statistic is of 0.22.

Solve to find the value of x.

Tresset [83]

Answer:

x=12

Step-by-step explanation:

We know that a right angle is 90 degrees. So we can make the equation $35+4x+7=90.$ Now, we can solve fore X! We can combine 35 and 7 to make the equation $4x+42=90$ . In order to isolate x we have to subtract 42 from both sides, getting us the equation $4x=48.$ Now, in order to isolate x we must divide each side by 4, getting us the equation $12=x$ . To prove that x=12, we can subsitute x for 12. This means that we can do $35+4(12)+7=90. Or, 35+48+7 =90,$ which simplified, is 90=90, making x=12 true. Hope this helps :)
