Answer:
<em>A or B, it's either one of the two</em>
Answer:
(0.6613, 8.3387)
Step-by-step explanation:
Let the heights of men be the first population and the heights of women be the second population. Then
We have
,
,
and
,
,
. The pooled
estimate is given by

The 99% confidence interval for the true mean difference between the mean height of the men and the mean height of the women is given by (if the samples are independent)
, i.e.,

where
is the 0.5th quantile of the t distribution with (15+7-2) = 20 degrees of freedom. So
, i.e.,
(0.6613, 8.3387)
hey mate,

<=>

As we know that 
then

<=> (x+4) = 0
<=> x = -4
so there is one solution x = -4
thanks
Answer:
The domain is all real numbers such that -6≤x≤-2, and the range is all real numbers greater than or equal to -4.
Step-by-step explanation:
The domain refers to the set of possible <u>input</u> values, so in the domain of a graph consists of all the input values shown on the x-axis, in this case, all numbers beetwen -6 and -2. The range is the set of possible <u>output</u> values, which are shown on the y-axis; in the graph, all numbers equal and higher than -4.
Answer:
<o=180-132=48
so,<s=24(The angle at the circumference is half of its corresponding angle at center)
