Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences ab

out the characteristics of a population. Suppose that, from a population of 65 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible?

Answer: 6,77,040 different random samples of four accounts are possible.

Step-by-step explanation:

We have to calculate the different random samples of four accounts are possible from the population of 65 bank accounts.

we are using combination formula for calculating various combination of four accounts:

= ^{n}C_{r}

Where,

n - total population of bank accounts

r - random samples drawn from the population

= ^{65}C_{4}

= \frac{n!}{r!(n-r)!}

= \frac{65!}{4!(65-4)!}

= \frac{65!}{4!(61)!}

= 6,77,040 different random samples of four accounts are possible.

If you divide 36 by 4, it equals 9, so each side is 9. Then you multiply 9 to 9, which equals 81 in^2.

Solve x2 – 8x + 15 &lt; 0.<br><br> Select the critical points for the inequality shown.
quester [9]

Answer:

x=3,5

Explanation:

x2−8x+15=0

Try to express the terms of the equation in square form.

Adding 16 both sides of the equation,

(x2−2⋅x⋅4+42)+15=16

or,(x−4)2+15−16=0

or,(x−4)2−1=0

or,(x−4)2−12=0

This is the a2−b2=(a+b)(a−b)form.

(x−4+1)(x−4−1)=0

or,(x−3)(x−5)=0

Now, equate both the terms to zero since both of them when multiplied, give zero.

Either,

x−3=0

∴x=3

Or,

x−5=0

∴x=5

Ans:x=3,5 Hope this helpsXD...!!

PLEASE HELP :D ( these are multi step equations )
AnnyKZ [126]
For the first problem the answer is -5/2

2x−7+10=−2

Step 1: Simplify both sides of the equation.
2x−7+10=−2
2x+−7+10=−2
(2x)+(−7+10)=−2

(Combine Like Terms)
2x+3=−2

Step 2: Subtract 3 from both sides.
2x+3−3=−2−3
2x=−5

Step 3: Divide both sides by 2.
2x/2=−5/2
x=−5/2

Answer:
x= -5/2
