The system of equations that could be used to determine the price of each apple and the price of each banana is:

3x + 4y = 6.50

10x + 5y = 17.50

Where x is the price of each apple and y is the price of each banana

Step-by-step explanation:

The given is:

  • Kylie went into a grocery store and bought 3 apples and 4 bananas, costing a total of $6.50
  • Lily went into the same grocery store and bought 10 apples and 5 bananas, costing a total of $17.50

We need to write a system of equations that could be used to determine the price of each apple and the price of each banana

Assume that x represents the price per apple, and y represents the price per banana

∵ The price of each apple is $x

∵ The price of each banana is $y

∵ Kylie bought 3 apples and 4 bananas for a total $6.50

- Multiply x by 3 and y by 4, then add the products and equate

  the sum by 6.50

∴ 3x + 4y = 6.50 ⇒ (1)

∵ Lily bought 10 apples and 5 bananas for a total $17.50

- Multiply x by 10 and y by 5, then add the products and equate

  the sum by 17.50

∴ 10x + 5y = 17.50 ⇒ (2)

The system of equations that could be used to determine the price of each apple and the price of each banana is:

3x + 4y = 6.50

10x + 5y = 17.50

Where x is the price of each apple and y is the price of each banana

Answer:

94 for the first one and 130 for the second

Step-by-step explanation:

Since A=6 and B=4

For the first one

13(6)+ 4(4)

For the second one

(6+4)*13

(10)*13= 130

A survey of 25 randomly selected customers found the ages shown (in years). The mean is 32.64 years and the standard deviation i
____ [38]

Answer:

See below for answers and explanations

Step-by-step explanation:

<u>Part A</u>

Assuming that conditions have been met for the interval, we use the formula \displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}} where \bar{x} represents the sample mean, t represents the critical value, s represents the sample standard deviation, and n is the sample size.

The critical value of t for an 80% confidence level with degrees of freedom df=n-1=25-1=24 is equivalent to t=1.317836

Thus, we can compute the confidence interval:

\displaystyle CI=\bar{x}\pm t\frac{s}{\sqrt{n}}\\\\CI=32.64\pm1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\\\\CI\approx\{30.17,35.11\}

Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.

<u>Part B</u>

The margin of error is \displaystyle t\frac{s}{\sqrt{n}}=1.317836\biggr(\frac{9.39}{\sqrt{25}}\biggr)\approx2.47
