Form the intersection for the following sets. M = { } N = {6, 7, 8, 9, 10} M ∩ N = {0, 6, 7, 8, 9, 10} {∅, 6, 7, 8, 9, 10} {6, 7

Answer:
The common element in both the sets is empty set.
M ∩ N = { }
Step-by-step explanation:
We have given two sets:
M={ } , N={6,7,8,9,10}
We have given two sets, the intersection of M and N is the set that contains elements that belong to M and to N at the same time. In simple words M ∩ N means common elements in both M and N.
In the given question one set is empty set. Since the empty set is included in any set, it is also included in N although we don't see it. Therefore the common element in both the sets is empty set
Thus the answer is:
M ∩ N = { } ....
Answer:
a
Step-by-step explanation:
if x is equal to -1, if you add 1 you get 0 so the answer is greater than or equal to 0
Complete question :
Wright et al. [A-2] used the 1999-2000 National Health and Nutrition Examination Survey NHANES) to estimate dietary intake of 10 key nutrients. One of those nutrients was calcium in all adults 60 years or older a mean daily calcium intake of 721 mg with a standard deviation of 454. Usin these values for the mean and standard deviation for the U.S. population, find the probability that a randonm sample of size 50 will have a mean: (mg). They found a) Greater than 800 mg b) Less than 700 mg. c) Between 700 and 850 mg.
Answer:
0.10935
0.3718
0.9778
0.606
Step-by-step explanation:
μ = 721 ; σ = 454 ; n = 50
P(x > 800)
Zscore = (x - μ) / σ/sqrt(n)
P(x > 800) = (800 - 721) ÷ 454/sqrt(50)
P(x > 800) = 79 / 64.205295
P(x > 800) = 1.23
P(Z > 1.23) = 0.10935
2.)
Less than 700
P(x < 700) = (700 - 721) ÷ 454/sqrt(50)
P(x < 700) = - 21/ 64.205295
P(x < 700) = - 0.327
P(Z < - 0.327) = 0.3718
Between 700 and 850
P(x < 850) = (850 - 721) ÷ 454/sqrt(50)
P(x < 850) = 129/ 64.205295
P(x < 700) = 2.01
P(Z < 2.01) = 0.9778
P(x < 850) - P(x < 700) =
P(Z < 2.01) - P(Z < - 0.327)
0.9778 - 0.3718
= 0.606
Answer:
1, 3, 7, 21!
Step-by-step explanation:
Answer:
32,000cm²
Step-by-step explanation:
It already has an area which is lengh×width
So you only have to multiply with the height which is 20.
