Answer:

c = $7n + $6

Step-by-step explanation:

$6 shipping for any size

$7 per necklace

let n equal the quantity of necklaces and c equal the total cost.

you buy n amount of necklaces and add the shipping cost to find your cost.

Answer:

What is the independent (input) variable?

n, the number of necklaces

What is the dependent (output) variable?

c, the total cost in dollars

What is the domain?  

n = 0, 1, 2, 3...

Which equation expresses the order’s total cost, c, as a function of the number of necklaces, n?

c(n) = 7n + 6

Which expression means “the total cost, including shipping, of 5 necklaces”?

c(5)

Listed below are pulse rates​ (beats per​ minute) from samples of adult males and females. Does there appear to be a​ difference
MrMuchimi

Answer:

There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.

Coefficient of Variation (male) = 33.44%

Coefficient of variation (female) = 28.35%

Step-by-step explanation:

Mean (male) = \frac{sum of x}{n} =\frac{1020}{16} =63.75

Mean (female) = \frac{sum of y}{n} = \frac{1214}{16} = 75.875

Standard Deviation (male) = \sqrt{\frac{sum(x-63.75)^2}{16-1} } =21.315

Standard Deviation (female) = \sqrt{\frac{sum(y-75.875)^2}{16-1} } = 21.512

Coefficient of Variation  = \frac{Std dev}{mean} *100

For male, CV = \frac{21.315}{63.75} *100=33.44%%

For female, CV = \frac{21.512}{75.875} *100=28.35%

Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.

What are the two ordered pairs for 5x=-1
jonny [76]
5x = -1

x = -1/5 = -0.2

That means that any ordered pair for the line will be (-0.2, y)

You can put any number in for y.

So two ordered pairs could be:

(-0.2, 1)
and
(-0.2, 2)

What would the graph of 10x + 7y < 49 look ?
navik [9.2K]

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

10x+7y

2. The equation of the line in slope intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

y=-\frac{10}{7}x+7

then:

m=-\frac{10}{7}\\\\b=7

4. Find the x-intercept. Make y=0. Then:

0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.
