Answer:
Step-by-step explanation:
To calculate the midpoint, you need to plug in the values of x and y into the midpoint formula.
M ( x1 + x2/2 , y1 + y2/2)
M [ -8 + 4/2 , -7 + 9/2]
M ( -2, 1)

The riddle answer is 24.
A riddle for the number 68 is: 12 more than 14 times 4
To find the volume of the box you have to do the formula for volume
the formula for volume is lxwxh aka length x width x height
so first you have to do 3/4 x 1/2
3/4 x 1/2 = 3/8
Next, you have to do 3/8 x 1/4
3/8 x 1/4 = 3/32
so the volume of the box is 3/32

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.
