4 0

( - 45, 0)

to find the x-intercept let y = 0 in the equation

x = 0 → $\frac{1}{3}$ x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

x-intercept = ( - 45, 0)

A family of four (two kids and two parents) spend the day at an amusement park. At the end of the day, the family adds up all of

Harrizon [31]

A family of four spent the following for their meals $16.25, $17.96, $3.58, $4.61, $5.23.

Mean cost spent is calculated by:

Total Cost/Number of Meals

(16.25+17.96+3.58+4.61+5.23)/5

47.63/5

$9.53

Mean Cost represents the average amount per meal the family has spent.

Median cost is the cost that in the middle of the five costs which is $5.23.

<span>The mean cost is significantly different from the median cost because it is higher.</span>

Median cost is a better representation of the amount of money that the family spent because, with<span> regard to meal costs, this means that exactly half of the meals in the amusement park are above this price ($5.23) and exactly half are below. </span>

In the following series, what two numbers come next? 2, 88, 80, 16, 11, 3, 30, 95

Liono4ka [1.6K]

A series can be arithmetic, geometric or neither

The two numbers that come next are 87 and 44

<h3>How to determine the complete series</h3>

The series is given as:

2, 88, 80, 16, 11, 3, 30, 95

In the above series, every 3rd number have a difference of 14.

So, we have:

[2], 88, 80, [16], 11, 3, [30], 95, __, [44]

The difference between other adjacent numbers is 8.

So, we have:

88 - 80 = 8

11 - 3 = 8

95 - x = 8

Collect like terms

x = 95 - 8

Evaluate the like terms

x = 87

So, the complete series is:

[2], 88, 80, [16], 11, 3, [30], 95, 87, [44]

Hence, the two numbers that come next are 87 and 44
