Answer:

  • $47.33
  • $43
  • $50.25

Step-by-step explanation:

Using table calculating the mean for each case

1. Entire year, sample size 12

  • x = 1/12* ∑ xi, i= 1 to 12
  • x = 1/12(40+42+40+38+48+50+58+62+56+46+44+44)
  • x = 1/12*568 = $47.33

2. First six months, sample size 6

  • x = 1/6*∑ xi, i= 1 to 6
  • x = 1/6(40+42+40+38+48+50)
  • x = 1/6*258 = $43

3. April through November, sample size 8

  • x = 1/8*∑ xi, i= 4 to 11
  • x = 1/8(38+48+50+58+62+56+46+44)
  • x = 1/8*402 = $50.25

ss7ja [257]

Answer:

The height of each step is 1957 yard

Step-by-step explanation:

we are given

Tristan is building steps up to a deck that is 15656 yards above the ground

so, total height =15656 yards

Number of steps =8

now, we can use formula

Height of each step = ( total height)/( number of steps)

now, we can plug these values

and we get

Height of each step is

=\frac{15656}{8}yards

=1957yards

Determine whether the following is an example of a sampling error or a non-sampling error. 12% of all people are left handed. A
const2013 [10]

Answer:

Sampling Error

Step-by-step explanation:

When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.

Can the sum of two mixed numbers be equal to 2? Explain why or why not.
Vesna [10]

-- A "mixed number" is (a whole number) plus (a fraction).

-- Two mixed numbers = (two whole numbers) and (two fractions).

-- The smallest whole number is ' 1', so when you add up all of that,
the smallest possible sum is      (2) plus (two fractions).

-- So the sum must always be greater than  2 .

============================================

<em>THAT'S IF BOTH MIXED NUMBERS ARE POSITIVE </em>.

<em>If one of them is negative</em>, then it's easy to do:

(3 and 1/2) + negative (1 and 1/2) = <u>2</u>

(25 and 7/10) + negative (23 and 7/10) = <u>2</u>
