Answer:

d= √ 72

Step-by-step explanation:

d=√ (1−7)2+(8−2)2

d=√ (−6)2+(6)2

d=√ 36+36

d=√ 72

yanalaym [24]

Given:
Cost of printing a catalog: flat rate of $52 and $0.20 per copy.

C = 52 + 0.20x

C is the total cost of printing x number of copies.

x = 500
C = 52 + 0.20(500) = 52 + 100 = 152

x = 1000
C = 52 + 0.20(1000) = 52 + 200 = 252

x = 1500
C = 52 + 0.20(1500) = 52 + 300 = 352

x = 2000
C = 52 + 0.20(2000) = 52 + 400 = 452

x = 2500
C = 52 + 0.20(2500) = 52 + 500 = 552

Six customers enter a three-floor restaurant. Each customer decides on which floor to have dinner. Assume that the decisions of

Firdavs [7]

<h2>Answer:</h2>

The probability that exactly one customer dines on the first floor is:

0.26337

<h2>Step-by-step explanation:</h2>

We need to use the binomial theorem to find the probability.

The probability of k success in n experiments is given by:

$P(X=k)=n_C_k\cdot p^k\cdot (1-p)^{n-k}$

where p is the probability of success.

Here p=1/3

( It represents the probability of choosing first floor)

k=1 ( since only one customer has to chose first floor)

n=6 since there are a total of 6 customers.

This means that:

$P(X=1)=6_C_1\times (\dfrac{1}{3})^1\times (1-\dfrac{1}{3})^{6-1}\\\\\\P(X=1)=6\times (\dfrac{1}{3})\times (\dfrac{2}{3})^5\\\\\\P(X=1)=0.26337$

Answer: 1.467

Step-by-step explanation:

Formula of Margin of Error for (n<30):-

$E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 22

Level of confidence = 0.90

Significance level : $\alpha=1-0.90=0.10$

By using the t-distribution table ,

Critical value : $t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743$

Standard deviation: $\sigma=4$

Then, we have

$E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467$

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467

Prove that the value of the expression 7^8–7^7 +7^6 is divisible by 43.

murzikaleks [220]

Step-by-step explanation:

1. if to evaluate the given experssion, then

7⁶(7²-7+1)=7⁶*43.

2. if to divide this evaluated expression by 43, then

7⁶*43/43=7⁶.
