This is a right triangle becuase the one angle is a right angle aka 90 degrees and if it is a right angle then it is a right triangle

It should be a right triangle as u can use phytgagrean theorem to figure it out basically a^2+b^2 = c^2 this works in this case as it should equal to 10^2 + 5 square root 2 and then Ans squared = 5 square root 6 then squared . At end it should equal to 150= 150

Which point on the number line is located at approximately 13/17

Dmitry_Shevchenko [17]

A number line consists only of one axis, conventionally a horizontal axis. Just create a line, and scale it according to practicality and your preference. Usually, it has an interval of 1 unit. But for this case, since it is in fraction form, the interval should be smaller so that you can see clearly where it is located.

In decimal form, 13/17 is equal to 0.7647058824. Let's just round this off to 0.764, that can suffice already. So, you would expect it to be between 0.7 and 0.8 on the number line. Just estimate visually where it is located. Since, it is more than 0.75, the dot would be just slightly closer to 0.8 than 0.7. The exact location is shown in the attached picture.

The temperature today was 10 degrees colder than twice yesterday's temperature, t.

Aneli [31]

Answer: Today's temperature : 2t -10

Step-by-step explanation:

Hi, to write the expression of the statement given we have to analyze each phrase:

Twice yesterday's temperature, t. If t is yesterday’s temperature, twice that temperature equals 2t.

The temperature today was 10 degrees colder than: It means that we have to subtract 10 degrees :(-10)

Mathematically speaking:

Today's temperature : 2t -10

where t = yesterday's temperature

When are conclusions said to be statistically significant?

mars1129 [50]

Answer:

If the p-value is less than a given significance level, you reject the null hypothesis and accept the alternative hypothesis.

Step-by-step explanation:

Suppose you have a business in which you'd like to make a change to increase your business. After making the change, you can use a significance test it. To conduct a significance test, you make a null hypothesis which states essentially that no effect happened. You also make an alternative hypothesis that states the change had an effect. You then test the two to see which one stands. In a significance test, using the p-value from your sample you compare it to the null and alternative hypotheses. You make a conclusion when:

If the p-value is less than a given significance level, you reject the null hypothesis and accept the alternative hypothesis since the evidence is in favor of it.

If the p-value is greater than the significance level, then you fail to reject the null hypothesis and cannot conclude. There isn't evidence in favor of the alternative hypothesis.
