The amount spent on food and drink by 20 customers is shown below What is the modal amount spent and the median?

Kaylis [27]

Answer:

Mode = 19.

Median = 23.

Step-by-step explanation:

Arrange in ascending order:

8 9 12 15 17 18 19 19 20 22 24 25 26 27 28 31 34 36 40 43

The modal amount is the one which occurs most , which is 19.

The median is the middle value of the 20 amounts.

As there is an even number of amounts the median is the mean of the 2 middle numbers:

Median = (22 + 24) / 2

= 23.

The expression 148 – 24d gives the number of pizzas a store has in stock, where d is the number of days. How many pizzas will th

Feliz [49]

Explanation

A function is defined as a relation between a set of inputs having one output each,in this case our independent variable is the number of days( d) and the dependent variable would be the number of pizzas

Step 1

let the function

$\begin{gathered} P=148-24d \\ where\text{ P is the number of pizzas } \\ and\text{ d is the number of days} \end{gathered}$

therefore, to know the number of pizzas are in the stock after 5 days we need to evaluate the equation for d=3

$\begin{gathered} P=148-24d \\ let\text{ d=5 and evaluate} \\ P=148-24(5) \\ P=148-120=28 \\ P=28 \end{gathered}$

so, after five day there willbe 28 pizzas in stock

I hope this helpsyou

The following graphs are transformations of f(x) = x^2.

KiRa [710]

Step-by-step explanation:

Let's look at A(x) and see how it is different from f(x)

it is shifted downwards by 8 units
it is not shifted to the left or the right

Therefore A(x) = f(x) - 8

Let's look at B(x) and see how it is different from f(x)

it is not shifted downwards or upwards
it is shifted to the left 7 units

Therefore B(x) = f(x + 7)

Let's look at C(x) and see how it is different from f(x)

it is shifted upwards by 4 units
it is shifted to right by 5 units

Therefore C(x) = f(x - 5) + 4

Let's look at D(x) and see how it is different from f(x)

it is not shifted downwards or upwards
it is not shifted to right by 12 units

Therefore D(x) = f(x - 12)
