Answer: 'X' = 24 degrees

Step-by-step explanation:

5 times 'X' = 120 degrees (because the formula is base times height divided by 2).

120 divided by 5 = 'X'

= 24

'X' = 24 degrees

Answer:

1) $\displaystyle\frac{5}{18}\approx27.78\%$

2) $\displaystyle\frac{4}{7}\approx57.14\%$

3) $\displaystyle \frac{13}{16}=81.25\%$

Step-by-step explanation:

We are given a two-way frequency table. Using the table, we will determine the probability for each case.

Question 1)

P(A Student With A Part Time Job Without A Car)

Using the first column, the total number of students that have a part time job is 78+30=108.

Likewise, using the first column, we can see that out of those 108 students, 30 do not have a car.

Hence, the probability that a student with a part time job without a car is:

$\displaystyle P=\frac{30}{108}=\frac{5}{18}\approx27.78\%$

Question 2)

P(No Car | Does Not Have A Part Time Job)

Remember that the vertical line means conditional probability.

So, we want the probability of a student having no car given that they do not have a part time job.

Using the second column, we can see that the total number of students that do not have a part time job is 18+24=42.

Likewise, using the second column, 24 do not have a car.

Hence, the probability that a student with a part time job without a car is:

$\displaystyle P=\frac{24}{42}=\frac{4}{7}\approx57.14\%$

Question 3)

P(Part Time Job | Car)

So, we want to probability of a student having a part time job given that they have a car.

Using the first row, the total students that have a car is 78+18=96.

And of those 96 students, 78 have a part time job.

Hence, the probability that a student with a car has a part time job is given by:

$\displaystyle P=\frac{78}{96}=\frac{13}{16}=81.25\%$

A company is selling toothpicks. It costs $0.03 to produce each toothpick and a fixed cost of $110 a month for the company. If t

AlexFokin [52]

<h3>11,000 toothpicks must be sold in order to break even.</h3>

Step-by-step explanation:

Here, let us assume the number of toothpicks sold to break even = m

So, for m toothpicks, Total cost = Total Earnings

Now, the cost of producing 1 toothpick = $0.03

So, cost of production of m toothpicks = m x ( cost of 1 toothpick)

= $(0.03 m)

Also, fixed month cost = $110

So, Total cost of production = $110 + $0.03 m .... (1)

Again, the selling cost of 1 toothpick = $0.04

So, selling cost of m toothpicks = m ( cost of 1 toothpick) = $(0.04 m) ..(2)

From (1) and (2)

110 + 0.03 m = (0.04 m)

⇒ 110 = 0.01 m

or, m = $\frac{110}{0.01} = 11,000$

⇒ m = 11,000

Hence, 11,000 toothpicks must be sold in order to break even.
