The answer is C because AO and BO are equal. And with AO being three times the length of CO, BO should be the length of DO
Step-by-step explanation:
Susan has a high chance of picking a yellow marble because she has more yellow than any color
The constant term in the equation is -20 because you will always be subtracting 20 no matter how big x is
Answer:
There is enough evidence to say that the true average heat output of persons with the syndrmoe differs from the true average heat output of non-sufferers.
Step-by-step explanation:
We have to perform a hypothesis test on the difference between means.
The null and alternative hypothesis are:

μ1: mean heat output for subjects with the syndrome.
μ2: mean heat output for non-sufferers.
We will use a significance level of 0.05.
The difference between sample means is:

The standard error is

The t-statistic is

The degrees of freedom are

The critical value for a left tailed test at a significance level of 0.05 and 16 degrees of freedom is t=-1.746.
The t-statistic is below the critical value, so it lies in the rejection region.
The null hypothesis is rejected.
There is enough evidence to say that the true average heat output of persons with the syndrmoe differs from the true average heat output of non-sufferers.
Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
