This is an arithmetic progression since the difference (d) between 2 consecutive terms is constant:

13=5 = 8

21-13 = 8

29-21 = 8, etc.

If a is the first number (5) & d=8 & n=100
Then value of the term X with nth rank ===>X(nth) = a+(n-1)d ===>
5+(100-1).8 = 797

Answer:

x=6

Step-by-step explanation:

44+3x=5x+2x+20

collect like terms:

44+3x=7x+20

move the terms :

3x-7x=20-44

collect like terms calculate :

-4x=-24

divide both sides:

x=6 is the final answer

Consider a population with 3 observations: 6, 10 and 12. You use simple random sampling without replacement to select a sample o

lozanna [386]

Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

Given that:

The number of observations is:

6, 10, 12

If we are to use a simple random sampling without replacement, then we will have:

(6,10) (6,12) (10,12)

Here;

the sample size n = 2

The population size N = 3

For (6,10) ; The sample mean = $\dfrac{6+10}{2}$

= $\dfrac{16}{2}$

= 8

For (6,12) ; The sample mean = $\dfrac{6+12}{2}$

= $\dfrac{18}{2}$

= 9

For (10, 12) ; The sample mean = $\dfrac{10+12}{2}$

= $\dfrac{22}{2}$

= 11

The probability distribution of sample mean(x) is:

X 8 9 11

P(X=x) $\dfrac{1}{3}$ $\dfrac{1}{3}$ $\dfrac{1}{3}$

Thus, the probability that the sample mean is larger than 8 is:

P(X> 8) = P(X = 9) + P(X + 11)

P(X> 8) = $\dfrac{1}{3}+\dfrac{1}{3}$

P(X > 8) = $\dfrac{1+1}{3}$

P(X> 8) = $\dfrac{2}{3}$

A resturant bill for a group of people comes to a total of $125 . The amount included an %8 of sales tax and a 20% tip both base

lora16 [44]

The price of food was $97.66

Step-by-step explanation:

Let x be the price of the food

If x is the price, then

Sales tax = 8% = 0.08x

Tip = 20% = 0.2x

Then the equation will be:

$x+0.08x+0.2x = 125\\1.28x = 125$

Dividing both sides by 1.28

$\frac{1.28x}{1.28} = \frac{125}{1.28}\\x = 97.66$

The price of food was $97.66
