Answer:
120960
Step-by-step explanation:
We get 11 books 7 of geography and 4 of chemistry
We need to line all of them with 2 constraints
1.-three of the geography must be: 1 in the middle and in each end, then we already have
C₄,₃ = 4! / ( 4 - 3 ) ! C₄,₃ = 4*3*2*1
C₄,₃ = 24 different ways
Now we have 7 books of chemistry. To place them we get
P₇ = 7! P₇ = 7*6*5*4*3*2*1 P₇ = 5040
Now the total number will be
C₄,₃* P₇ = 120960

Answer:-5k6
Step-by-step explanation:
Answer:
The following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed(that is, skewed to the right).
Step-by-step explanation:
In a normal distribution the properties of which are given as follows:
i) all the central tendency measures, that is, the mean, the median and the mode are equal.
ii) The area under the bell curve is equal to one.
iii.) The bell curve is symmetric about the center, or mean.
iv.) The bell curve does not touch the x - axis.
Therefore only the following is NOT TRUE about the normal distribution, that is, d.) The curve is right-skewed (that is, skewed to the right).
