Answer:
T = 290
Step-by-step explanation:
We can find the sum of all observations multiplying sample size (n) by sample mean (x).
Sum of all observations in the data set is,
Hope this helps!
we know that
in the right triangle ABC
the value of cosine of angle x is equal to
we have
substitute the values
Find the measure of angle x
Round to the nearest whole degree
therefore
<u>the answer is</u>
Given that the first spinner has three equal sectors labelled 1, 2 and 3; and the second spinner has equal sectors labelled 3, 4, 5 and 6.
The number of possible outcomes that do not show a 1 on the first spinner is 2 (i.e. the first spinner shows 2 or 3).
The number of possible outcomes that the second spinner show the number 4 is 1 (i.e. the second spinner shows 4)
In probability, the word 'and' goes with multiplication.
Therefore, <span>the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner</span> is given by 2 x 1 = 2 possible outcomes.
i.e. the first spinner shows the number 2 and the second spinner shows the number 4 or the first spinner shows the number 3 and the second spinner shows the number 4.
What’s the question???...
