amid [387]

Answer:

(38.1,88.6)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = 38.3

Sample size, n = 695

Alpha, α = 0.05

Population standard deviation, σ = 3.6

95% Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

38.3 \pm 1.96(\frac{3.6}{\sqrt{695}} ) = 38.3 \pm 0.267 = (38.033,38.567) \approx (38.1,88.6)

AnnZ [28]

Answer:

  • A. 3 weeks, $160

Step-by-step explanation:

If the value of y is same for both then we have equal right sides of equations

  • 50x + 10 = 30x + 70

Solve this for x

  • 50x - 30x = 70 - 10
  • 20x = 60
  • x = 60/20
  • x = 3

Find the value of y

  • y = 50*3 + 10 = 150 + 10 = 160

Correct choice is A

A grocery store sells almonds for $7/1b and peanuts for $5/lb. Let x represent the number of pounds of almonds, and let y
jenyasd209 [6]

Answer:

7x+ 5y <= 10

Step-by-step explanation:

As the x represents the number of pounds of almonds and the price of the almonds is $7/lb, we need to look for an inequality where the x is multiplied by $7 and the same with the y and $5.

It's useless to multiply the x by $5 or the y by $7 because we are mixing the prices of the nuts.

On the other hand, we don't want to spend more than 10. That means we can spend 10 or less.

Therefore, the inequality we can use to find how much of each type of nut we can buy without spending more than $10 is

7x+ 5y <= 10
