Answer:
D.) 7
Step-by-step explanation:
To calculate the check digit, multiply every even-position digit (when counted from the right) in the number by two. If the result is a two digit number, then add these digits together to make a single digit (this is called the digital root):
Odd numbers: (1.)= 8 (3.)= 4 (5.)= 6 (7.)= 0 (9.)= 4 (11.)= 6 (13.)= 2 (15.)=(1 + 6)= 7
Even numbers: (2.)= 3 (4.)= 8 (6.)= 1 (8.)= 3 (10.)= 6 (12.)=5 (14.)=0
To this total, we then add every odd-position digit:
Odd = 37
Even = 26
This will result in a total:
37 + 26 = 63
The check-digit is what number needs to be added to this total to make the next multiple of 10:
Next multiple of 10 is 70.
70 - 63 = 7
Answer:
7

Considering the Central Limit Theorem, we have that:
a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
b) The probability can be calculated, as the sample size is greater than 30.
<h3>What does the Central Limit Theorem state?</h3>
It states that the sampling distribution of sample means of size n is approximately normal has standard deviation 
, as long as the underlying distribution is normal or the sample size is greater than 30.
In this problem, the underlying distribution is skewed right, that is, not normal, hence:
- For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
- For item b, the probability can be calculated, as the sample size is greater than 30.

Clown fish: angel fish 5:4
angle fish: gold fish 4:3
(60): angel fish=5:4
(5)(12)=60
(4)(12)=48 angel fish
(48): gold fish=4:3
(4)(12)=48
(3)(12)=36 gold fish
Answer:
Step-by-step explanation:
Isabell, can you see that the sides are 2x6 each? each half of the triangle will make a total rectangle of 2x6 or 12 square meters
there are 4 of those so 48 sq meters plus the base of 4x4 or 16 sq meters
48+16 = 64 square meters total
Answer:
3
Step-by-step explanation:
The sum of these two polynomials is - 2 x^2 - 3. the two x variables are additive inverses and -6 x^2 and 4 x^2 equal - 2 x^2 and -3 results from -4 and 1
Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3
