What does the central limit theorem tell us about the
distribution of those mean ages?
<span>A. </span>Because n>30, the sampling
dist of the mean ages can be approximated by a normal dist with a mean u and a
SD o/sqrt 54,
Whenever n<span>>30 the central limit theory applies.</span>
Answer:
if travis tells her to take care of the baby
Step-by-step explanation:
Answer:
2 a. x= -2, x=10 2 b. x= -7, x=7
Step-by-step explanation:
move the -6 to the left to get
-7 x lx-4l = -42
divide both sides of the equation by -7
lx-4l = 6
separate into
x-4=6 and x-4= -6
solve by adding 4 to both sides
then on the other one add 4 to both sides
2b you do the same steps just different numbers
Answer:(2, 4)
Step-by-step explanation:
Answer:
b. 10
Step-by-step explanation:
For the most part, these are problems in addition. The measures of the different angles add up according to the relationships given in the problem statement.
From the picture, you can tell that ∠JKN is the sum of ∠1 and ∠2, which are said to be equal (congruent). That is, ∠1 has a measure that is half of that of ∠JKN.
Since ∠JKN is a right angle, 90°, and the measure of ∠1 is half that, m∠1 is 45°.
So, to find t, we equate the given expression for m∠1 to 45 and solve.
4t +5 = 45
4t = 40 . . . . . subtract 5
t = 10 . . . . . . . divide by 4 . . . . . matches answer choice B
