Answer:

A and D

Step-by-step explanation:

To find the x intercepts, substitute 0 into y.

2x = 6

(3,0)

To find the y intercept, substitute 0 into x;

3y = 6

(0, 2)

So a and d

Unit sales for new product ABC have varied in the first seven months of this year as follows: Month Jan Feb Mar Apr May Jun Jul

Alecsey [184]

Answer:

$\sigma = 121.53$

Step-by-step explanation:

Required

The population standard deviation

First, calculate the population mean

$\mu = \frac{\sum x}{n}$

This gives:

$\mu = \frac{148+ 329+ 491 +167+ 228+285+ 441}{7}$

$\mu = \frac{2089}{7}$

$\mu = 298.43$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

So, we have:

$\sigma = \sqrt{\frac{(148 - 298.43)^2 + ..........+ (441- 298.43)^2}{7}}$

$\sigma = \sqrt{\frac{103387.7143}{7}}$

$\sigma = \sqrt{14769.6734714}$

$\sigma = 121.53$

Shay works each day and earns more money per hour the longer she works. Write a function to represent a starting pay of $20 with

Masja [62]

Answer:

<u>Function</u>: $p(x)=20(1.04)^x$

<u>Range</u>: option D. 20 ≤ x ≤ 27.37

Explanation:

The function must meet the rule that the pay starts at $20 and it increases each hour by 4%.

A table will help you to visualize the rule or pattern that defines the function:

x (# hours) pay ($) = p(x)

0 20 . . . . . . . . [starting pay]

1 20 × 1.04 . . . [ increase of 4%]

2 20 × 1.04² . . . [increase of 4% over the previous pay]

x 20 × 1.04ˣ

Hence, the function is: $p(x)=20(1.04)^x$

The range is the set of possible outputs of the function. To find the range, take into account that this is a growing exponential function, meaning that the least output is the starting point, and from there the output will incrase.

The choices name x this output. Hence, the starting point is x = 20 and the upper bound is when the number of hours is 8: 20(1.04)⁸ = 27.37.

Then the range is from 20 to 27.37 (dollars), which is represented by 20 ≤ x ≤ 27.37 (option D from the choices).

F is the midpoint of EG If EF = x + 2 and FG = 2x - 6, find<br> FG

mezya [45]

Answer:

FG = 10

Step-by-step explanation:

EF = x + 2 ; FG = 2x - 6

F is the mid-point of EG. So, EF = FG

$= > x + 2 = 2x - 6$

$= > 2x - x = 6 + 2$

$= > x = 8$

FG = 2×8 - 6 = 10
