The Sample Mean of hours slept of the ten men asked is 8.4 hours.
The population Mean of hours slept of all the members of the theater group is 8.3 hours.
Answer:
The first digit of a two digit number can be any of digits 1 - 9. It cannot be 0 though. Therefore there are 9 possible digits for the first place.
There are 5 possible digits for the second position. The two digit number has to be odd and therefore the final digit must be 1,3,5,7 or 9
Therefore for each and every one of the nine first digits there are 5 digits that the second can be.
Therefore ANSWER = 9 * 5 = 45 possible permutations.
2. The largest two digit number = 99
Subtract 57 and you get 42
ANSWER = 42
The forty two numbers are 58 ,59, 60, 61......98, 99
I would go with A but I am not 100% sure so you may want to check however you can.
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
Answer:
SY=34, SK=21 and KY=13
Step-by-step explanation:
we have that
SY=SK+KY
substitute the given values
(36-x)=(13x-5)+(2x+9)
solve for x
36-x=15x+4
15x+x=36-4
16x=32
x=2
<em>Find the value of SY</em>
SY=(36-x)=36-2=34
<em>Find the value of SK</em>
SK=(13x-5)=13(2)-5=21
<em>Find the value of KY</em>
KY=(2x+9)=2(2)+9=13
