C! All angles are the same
Answer:
Step-by-step explanation:
Given that for X the amount of credit card debt for U.S. adults under 35, is
having mean as 8724 dollars.
For this point estimate to be unbiased and most accurate we must ensure that
i) The sample represents the population
ii) Samples are drawn at random
iii) Sample sizes are sufficienly large.
Hence we see that C is not right as college students cannot represent the entire population. Tv poll cannot be said to be random since there may be a significant population who was not aware about this poll. A and B are right but B is better with more sample size.
15.90 times 3 equals your answer 47.70 hope I helped
Answer:
13.92
Step-by-step explanation:
We have that the critical z-score associated with 85% to the left is 1.04, we know that by table.
So we have to:
m + z * (sd) = 16
where m is the mean, z is the critical z-scor and sd is the standard deviation, if we replace we are left with:
m + 1.04 * (2) = 16
m = 16 - 1.04 * (2)
m = 13.92
Therefore, the average weight if 85% of cucumbers weigh less than 16 ounces is 13.92
Answer:
(2p-1)(p-1)
Step-by-step explanation:
=> 2p(p-1)-p+1
Opening brackets
=> 2p²-2p-p+1
=> 2p²-3p+1
Using mid-term break formula
=> 2p²-2p-p+1
=> 2p(p-1)-1(p-1)
=> (2p-1)(p-1)
