Trent ordered 3 veggie sandwiches and 2 meat sandwiches.

Step-by-step explanation:

Given,

Total sandwiches ordered = 5

Total amount spent = $22

Cost of one veggie sandwich = $4

Cost of one meat sandwich = $5

Let,

x be the number of veggie sandwiches

y be the number of meat sandwiches

According to given statement;

x+y=5       Eqn 1

4x+5y=22   Eqn 2

Multiplying Eqn 1 by 4

4(x+y=5)\\4x+4y=20\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(4x+5y)-(4x+4y)=22-20\\4x+5y-4x-4y=2\\y=2

Putting y=2 in Eqn 1

x+2=5\\x=5-2\\x=3

Trent ordered 3 veggie sandwiches and 2 meat sandwiches.

In a sample of n = 6 scores, 5 of the scores are each above the mean by one point. Where is the 6th score located relative to th
den301095 [7]

The mean of a dataset is the sum of all data elements divided by the count of the elements.

The location of the 6th score relative to the mean is 5 points below the mean

Let:

\bar x \to<em> Mean</em>

a \to<em> 5 scores</em>

b \to<em> 6th scores</em>

Given that:

n = 6

The 5 scores that are 1 above the mean implies that:

a = \bar x + 1

The mean of a dataset is calculated using:

\bar x = \frac{\sum x}{n}

So, we have:

\bar x =\frac{5a + b}{6}

\bar x =\frac{5(\bar x + 1) + b}{6}

Open brackets

\bar x =\frac{5\bar x + 5 + b}{6}

Multiply both sides by 6

6\bar x =5\bar x + 5 + b

Make b the subject

b = 6\bar x -5\bar x - 5

b = \bar x - 5

This means that the 6th score is 5 points below the mean
