What is the mode of Variable A? Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The
klemol [59]
Variable A : 1, 2, 4, 4, 5, 6, 7, 9

Mode is the number that appears more frequently in the data set than other numbers.

1, 2, 5, 6, 7, and 9 only appeared once.
4 appeared twice.

So, the mode of the data set is 4.

Additional info:
mean = (<span>1 + 2 + 4 + 4 + 5 + 6 + 7 + 9) / 8 = 38 / 8 = 4.75
median = (4 + 5) / 2 = 9 / 2 = 4.5
range = 9 - 1 = 8</span>

John has a gift card of $100. He spends $5 per day. Write an equation to show the amount left on the card after x days
ch4aika [34]

Answer:

y = 100 - 5x

Step-by-step explanation:

Total amount of gift card = $100

Amount spent per day = $5

Number of days = x days

Write an equation to show the amount left on the card after x days

y = 100 - 5x

Where,

y = amount left on the gift card

x = number of days

For example,

Assume x = 2 days

Amount left on the gift card, y

y = 100 - 5x

y = 100 - 5(2)

= 100 - 10

= 90

y =$90
