The cost per ounce of a drink, c, varies inversely as the number of ounces, n. Six ounces of the drink costs 60 cents per ounce.

kaheart [24]

Answer:

c = 360/n

Step-by-step explanation:

From the question, we are told that:

The cost per ounce of a drink, c, varies inversely as the number of ounces, n.

Mathematically this is expressed as:

c ∝ 1/n

Using the constant of proportionality k

c = k/n

Six ounces of the drink costs 60 cents per ounce.

c =60 cents per ounce

n = 6 ounces

Mathematically we have

c = k/n

60 = k/6

Cross multiply to find the constant k

k = 60 × 6

k = constant of proportionality = 360

Therefore, using the mathematically expression "c = k/n" the equation that represents this relationship is

c = 360/n

a gardener is putting a wire fence along the edge of his garden to keep animals from eating his plants. if he has 20meters of fe

Alexeev081 [22]

Answer:

The largest rectangular space is $24m^{2}$

Step-by-step explanation:

Given a 20m long wire fence, implies that the perimeter of the fence has been given, because Perimeter can be defined as the length of the boundary of a figure (in this case, a rectangle)

So, from the formula: Perimeter = 2 (L + B) = $20m^{2}$

We have that L + B = $10m^{2}$

The possible values of L and B are:

(L, B) = (9, 1), (8, 2), (7, 3) and (6, 4).

The areas of the rectangle that will be formed using these values are respectively; $9m^{2}$ , $16m^{2}$ , $21m^{2}$ and $24m^{2}$ , the largest area of which is the last which corresponds to the values (6, 4).

The largest rectangular space that the gardener can enclose is therefore $24m^{2}$

Can y’all help me with the 1st and 2nd one plz

kherson [118]

1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.

2. 3/4 > 5/8 the least common denominator is: 8

Rewriting as equivalent fractions with the LCD:

3/4 = 6/8 5/8 = 5/8

Comparing the numerators of the equivalent fractions we have:

6/8 > 5/8

consider the following scenario: Assume daily protein intake values in a population of athletes are known to have a standard dev

Kipish [7]

Answer:

The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96*\frac{58.6}{\sqrt{267}} = 7.03$

The lower end of the interval is the sample mean subtracted by M. So it is 77 - 7.03 = 69.97g.

The upper end of the interval is the sample mean added to M. So it is 77 + 7.03 = 84.03g.

The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.
