It has a 31% chance. i used a calculator. so i guess the best answer is B.
Bonus answer is 4y cube 2 - 56y+52
Answer:
All four sets of numbers
Step-by-step explanation:
3 to the power of 2 is 9. real numbers are all numbers, whole numbers are the counting numbers plus zero, integers are whole numbers with their opposites ( 3 and -3), rational numbers are any numbers that can be written as a fraction, or is a decimal with an end or a repeated pattern to it.
So you want to get all of the unknowns on one side and all the kknowns on the other (this only works with one placeholder)
with equation you must do the same thing to both sides (except divide by 0 which is not allowed and undifined) so that the equation stays equall so
14y-51=187+4y
so add 51 to both sides
14y=238+4y
subtract 4y from both sides
10y=238
divide both sides by 10
y=23.8
(y=17 would make the equation false)
answer is y=23.8
Answer:
The t-score of 2.715 should be used
Step-by-step explanation:
Degrees of freedom ==> n - 1 ==> 38 - 1 ==> 37
to find 99% confidence interval, Hence,
Find t0.005 in front of 37 degrees of freedom,
Therefore the answer is, t-score = 2.715
