Answer:

l = large cups       amount of large cups = 16 x  ounces

small cups = 2x     amount of small cups = 8 (2x)      summed = 320 ounces

16x      +     8 (2x)       =    320        solve for 'x' the number of 16 ounce cups, the 8 ounce cups = 2x

Step-by-step explanation:

l = large cups       amount of large cups = 16 x  ounces

small cups = 2x     amount of small cups = 8 (2x)      summed = 320 ounces

16x      +     8 (2x)       =    320        solve for 'x' the number of 16 ounce cups, the 8 ounce cups = 2x

Answer:

[tex]-1/x^2[/tex]

Step-by-step explanation:

First, let's simplify the expression on the right:

[tex]1/\sqrt{x^2}=1/x[/tex]

Next, rewriting 1/x as x⁻¹, we can use the power rule to differentiate both sides with respect to x:

[tex]y=x^{-1}\\dy/dx=d/dx(x^{-1})\\dy/dx=-x^{-2}=-1/x^2[/tex]

Answer:

[tex]n1 = 9[/tex] and [tex]n2 = 9[/tex]

[tex]df1 = 8[/tex] and [tex]df2 = 8[/tex]

[tex]df = 16[/tex]

Step-by-step explanation:

Given

The above data

Solving (a): n1 and n2

This is the number of rows in each category

For sample A

[tex]n1 = 9[/tex]

For sample B

[tex]n2 = 9[/tex]

Solving (b): df1 and df2

This is calculated as:

[tex]df = n - 1[/tex]

For n1:

[tex]df1 = n1 - 1[/tex]

[tex]df1 = 9 - 1[/tex]

[tex]df1 = 8[/tex]

For n2:

[tex]df2 = n2- 1[/tex]

[tex]df2 = 9- 1[/tex]

[tex]df2 = 8[/tex]

Solving (c): Total df

Since there 2 categories of data, the total degrees of freedom is:

[tex]df = n1 + n2 - 2[/tex]

[tex]df = 9 + 9 - 2[/tex]

[tex]df = 16[/tex]

Answer:

6xy(x+2y)

Step-by-step explanation:

6x²y+12xy²

The GCF between 6 and 12 is 6. Factor out 6.

= 6(x²y+2xy²)

The GCF between x² and x is x. Factor out x.

= 6x(xy+2y²)

The GCF between y and y² is y. Factor out y.

= 6xy(x+2y)

Therefore, the GCF of the expression is 6xy and the factored expression is 6xy(x+2y).

Answer:

The ant has to crawl an approximate distance of 29mm

Step-by-step explanation:

Given

[tex]Volume = 8792mm^3[/tex]

[tex]r = 20mm[/tex] --- radius

See attachment

Required

Distance the ant has to crawl (i.e. the slant height)

First, we calculate the height of the hill

The volume of a cone is:

[tex]Volume = \frac{1}{3}\pi r^2h[/tex]

[tex]8792 = \frac{1}{3} * \frac{22}{7} * 20^2*h[/tex]

[tex]8792 = \frac{1}{3} * \frac{22}{7} * 400*h[/tex]

[tex]8792 = \frac{22* 400}{3*7} *h[/tex]

Make h the subject

[tex]h = \frac{8792 * 3 * 7}{22 * 400}[/tex]

[tex]h = \frac{184632}{8800}[/tex]

[tex]h = 20.98mm[/tex]

To calculate the slant height (s), we apply Pythagoras theorem

[tex]s^2=h^2 + r^2[/tex]

[tex]s^2=20.98^2 +20^2[/tex]

[tex]s^2=840.1604[/tex]

[tex]s=\sqrt{840.1604[/tex]

[tex]s=28.9855205232[/tex]

[tex]s= 29mm[/tex] --- approximated

Answer:

The value of the test statistic is -2.64.

Step-by-step explanation:

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the expected(claimed) mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

An automobile manufacturer claims that its van has a 40.3 miles/gallon (MPG) rating.

This means that [tex]\mu = 40.3[/tex]

After testing 250 vans, they found a mean MPG of 39.9. Assume the standard deviation is known to be 2.4.

This means, respectively, that:

[tex]n = 250, X = 39.9, \sigma = 2.4[/tex]

So

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{39.9 - 40.3}{\frac{2.4}{\sqrt{250}}}[/tex]

[tex]t = -2.64[/tex]

The value of the test statistic is -2.64.

Answer:

Domain: [-4, ∞]

Range: [-6, ∞]

Step-by-step explanation:

The domain is the set of the possible x values

The range is the set of the possible y values.

In the graph, we can see that the function cuts in a given part. We can see that for the x-values, the smallest one is x = -4, and then the function extends to the right (we see no limit at the right, then there is none)

This means that the domain is:

D: [-4, ∞]

For the y-values, the smallest value is when x = -4, and the y-value is -6

Then we can see that, as x increases, the same happens for y.

Then the range is:

R: [-6, ∞]

The required figure has been attached below could be the result of dilating a given triangle with a scale factor greater than 1. The correct answer would be an option (C).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The triangle has points (0, 0), (0, 3), and (6, 0) which are given in the question.

As per option (C), we have

On a coordinate plane, a triangle has points (0, 0), (0, 5), and (10, 0).
