Step-by-step explanation:
Hey, there!!
C = {6,8}
n(C) means cardinality of set.
We define cardinality of set as the no. of elements present in set.
It contains 2 no. of elements.
so, its cardinality is n(C) is 2.

Answer:
There were total 4 samples collected and each sample had a sample size of n = 100.
Step-by-step explanation:
We are given the following information in the question:
Collection of samples:




Hence, there were total 4 samples collected and each sample had a sample size of n = 100.
Answer:
Look down below!
Step-by-step explanation:
Fist, make your inequality:
-x + 5y > -10
5y > x - 10
y = .2x - 2
Now, plug in any value of x to find y!
Ex: x = 5...
y = .2 (5) - 2
y = -1
Your first coordinate could be (5, -1)
Hope this helps!
Answer:
9
Step-by-step explanation:
2/5 x 2 = 4/5
4/5 x 2, or 2/5 x 4 = 1 3/5
1 3/5 x 2, or 2/5 x 8 = 3 1/5
3 1/5 + 2/5, or 2/5 x 9 = 3 3/5
STEP 1
Mean =

STEP 2
Subtract the mean from each data value then square the answer

STEP 3
Add the squared answers in STEP 2 then find the mean

STEP 4
Square root the answer in STEP 3

Standard deviation is 236.5
