In a survey of 248 people, 156 are married, 70 are self-employed, and 25 percent of those who are married are self-employed. If

MatroZZZ [7]

Answer:

The probability of selecting a person which is self-employed but not married equals 1/8.

Step-by-step explanation:

Here, the given survey says:

Total number of people surveyed = 248

Number of people married = 156

The number of people are self employed = 70

Now, 25% of people who are married are SELF EMPLOYED.

Now, calculating 25% of 156 , we get:

$\frac{25}{100} \times 156 = 39$

⇒ out of total 156 married people, 39 are self employed.

So, number of self employed people but not married

= Self employed people - Self employed people PLUS married

= 70 - 39 = 31.

So, the probability that the person selected will be self-employed but not married = $\frac{\textrm{The total number of people self-employed but not married}}{\textrm{Total Number of people}}$ = $\frac{31}{248} = \frac{1}{8}$

Hence The probability of selecting a person which is self-employed but not married equals 1/8.

A factory makes candles. Each candle is in the shape of a triangular prism, as shown below. If the factory made 35 such candles,

Llana [10]

Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120

D. False

<h3>What is Function?</h3>

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

A. Since x-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.

False, it is the y-intercept of the function that indicates the amount at the start of the experiment.

B. Since y-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start.

True, the y-intercept is given when x = 0, indicating the initial value of the function.

C. Since the maximum value in the table for bacteria A is greater than the maximum value in the table for bacteria B, bacteria A has a faster growth rate than bacteria B.

False, because the maximum value of each table is given in different times, and also the initial value of each table is different.

D. Since the minimum value in the table for bacteria A is less than the minimum value in the table for bacteria B, bacteria A has a slower growth rate than bacteria B.

False, the growth rate is not given by the initial value. If we model both tables with an exponential function, the count of bacteria A quadruped in two days, and the count of bacteria B doubled in one day, so they have the same growth rate.
