Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one b
dezoksy [38]

Answer:

  • Burgers - $8.29 and fries - $4.39

Step-by-step explanation:

<u>Let burgers - b, fries - f</u>

  • 8b + 3f = 79.49
  • 12b + 6f = 125.82

<u>Double the first equation and subtract the second equation:</u>

  • 16b + 6f - 12b - 6f = 2(79.49) - 125.82
  • 4b = 33.16
  • b = 33.16/4
  • b = 8.29

<u>Find f:</u>

  • 8(8.29) + 3f = 79.49
  • 3f = 79.49 - 66.32
  • 3f = 13.17
  • f = 13.17/3
  • f = 4.39

You plan to conduct a survey to find what proportion of the workforce has two or more jobs. You decide on the 95% confidence lev
Vikentia [17]

Answer:

865

Step-by-step explanation:

We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.

Now we have the following formula:

n = [z / E] ^ 2 * (p * q)

where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.

Replacing these values we are left with:

n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]

n = 864.36

865 by rounding to the largest number.

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:
maxonik [38]

Answer:

a_{n} = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

a_{n} = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
