This is an incomplete question, the correct question is given below.

Find the missing number of each unit rate \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Answer : The missing number of each unit rate of \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1} are, 3 and 4 respectively.

Step-by-step explanation :

As we know that a unit rate is a rate in which 1 is present in denominator.

Or we can say that,

A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.

As we are given that that unit rates:

\frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Now we have to determine the missing number of each unit rates.

So, we can write the given expression as:

\frac{15}{5}=\frac{?}{1}

When are dividing 15 by 5, we get:

\frac{15}{5}=\frac{3}{1}

Thus, the missing number is, 3

And

\frac{24}{6}=\frac{?}{1}

When are dividing 24 by 6, we get:

\frac{24}{6}=\frac{4}{1}

Thus, the missing number is, 4

The pita‑franchise owner has observed in the past that waiting times tend to have a long tail to the right, with most customers
seropon [69]

Answer:

The two‑sample t ‑test is not appropriate because the distributions are not normal and the sample sizes are too small.

Step-by-step explanation:

The complete question is:

The owner of a pita franchise with two locations is interested in the average time that customers spend waiting for service at each store. She believes that the average waiting time at the original location is higher than the average waiting time at the new location.

The pita‑franchise owner has observed in the past that waiting times tend to have a long tail to the right, with most customers served relatively quickly and a few rare customers required to wait a very long time.Is a two‑sample t ‑test appropriate in this setting?The two‑sample t ‑test is appropriate because this is a comparison of the means of two continuous, random variables.The two‑sample t ‑test is not appropriate because the two samples do not have the same size.The two‑sample t ‑test is not appropriate because the sample standard deviations are not equal.The two‑sample t ‑test is not appropriate because the distributions are not normal and the sample sizes are too small.The two‑sample t ‑test is appropriate because the samples are random and contain no outliers, and the populations are normal.

For two sample t-test the distributions must be normal. Here the data, as mentioned in the questions is skewed to the right with long waiting times in the past.

190 = 6n - 2(-8n - 7)
andrew11 [14]

Answer:

n=8

  • First you remove the parentheses making it 190=6n+16n+14
  • Then you combine like terms making it 190=22n+14
  • After that, you move the terms making it -22n=14-190
  • After that, you calculate and that gives you -22n=-176
  • Lastly, you divide both sides leaving you with n=8

In the circle above, RV and SW are chords which intersect at point T. If ST = 4 ft, TV = 8 ft, and TW = 12 ft, what is the lengt
ElenaW [278]

Answer:

  6 ft

Step-by-step explanation:

The product of lengths from the point of intersection of the chords to the circle is a constant. For these chords, that constant is ...

  ST·TW = (4 ft)(12 ft) = 48 ft²

Then RT can be found from ...

  RT·TV = 48 ft²

  RT = (48 ft²)/TV = (48 ft²)/(8 ft)

  RT = 6 ft

svetoff [14.1K]

The profit equation which relates P, profit to N, quantity produced and sold is:

P=17.75N-750

What is the total cost function?

The total production cost function, whereby total cost is C is as given below:

C=750+15.95N(look at a similar question provided)

What is the total revenue function?

The total revenue function is as given below:

R=33.70N

The profit is the excess of total revenue over total cost, in other words, profit is the total revenue minus total cost

P=33.70N-(750+15.95N)

P=33.70N-750-15.95N

P=33.70N-15.95N-750

P=17.75N-750
