Hello!
The definition of the Central Limi Theorem states that:
Be a population with probability function f(X;μ,δ²) from which a random sample of size n is selected. Then the distribution of the sample mean tends to the normal distribution with mean μ and variance δ²/n when the sample size tends to infinity.
As a rule, a sample of size greater than or equal to 30 is considered sufficient to apply the theorem and use the approximation.
X[bar]≈N(μ;σ²/n)
If the variable of interest is X: the number of accidents per week at a hazardous intersection.
There is no information about the distribution of this variable, but a sample of n= 52 weeks was taken, and since the sample is large enough you can approximate the distribution of the sample mean to normal. With population mean μ= 2.2 and standard deviation σ/√n= 1.1/√52= 0.15
I hope it helps!
Step 1. Find the Greatest Common Factor (GCF)
GCF = 7x^2
Step 2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
7x^2(14x^4/7x^2 + 35x^2/7x^2)
Step 3. Simplify each term in parentheses
7x^2(2x^2 + 5)
Answer:
A)-The number 5 2/3 is less than 6 1/5
Step-by-step explanation:
I got it right :D
i believe u r confused about the 5 tanks because 18 can not fit into 5. so here is what it would accurately be.
to find out how many tanks you need your going to need to find the least common multiple. the least common multiple for both are below
18: 1, 2, 3, 6, 9, 18
24:1, 2, 3, 4, 6, 8, 12, 24
the least common multiple is 3. you will need three tanks. now for part b of this equation, to find out how many of each need to be put into the tank. to find this out you need to divide 18 plant and 24 fish by 3 tanks.
18/3 = 6
24/3 = 8
6 plants will go in each tank and 8 fish will go in each tank
the ratio is 6:8 per tank
