Probabilities are used to determine the chances of events

The probability that a randomly selected person with multiple jobs is a male or married is  0.782

<h3>How to determine the probability</h3>

The given parameters are:

Sample size, n = 655

Male = 381

Married = 299

Male and Married = 168

The number of those that are male or married is calculated as:

Male or Married = Male + Married - Male and Married

So, we have:

Male or Married = 381 + 299 - 168

Evaluate

Male or Married = 512

The probability is then calculated as:

p = 512/655

Evaluate

p = 0.782

Hence, the probability that a randomly selected person with multiple jobs is a male or married is  0.782

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza
VARVARA [1.3K]

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344

rusak2 [61]

The computation shows that the time taken is 120 minutes.

<h3>How to illustrate the information?</h3>

From the information, Andrew is riding his bike and he biked a distance of 14 miles at a rate of 7 miles per hour.

Therefore, time taken for 14 miles will be:

= 14/7

= 2 hours

= 2 × 60 = 120 minutes

The time taken is 120 minutes.

Bcc Medical Radiography program had 139 graduates. There were 25 more females than males. How many females and males graduated?
NISA [10]
F=m+25

m+f=139, using f from above we have:

m+(m+25)=139

2m+25=139

2m=114

m=57, and since f=m+25

f=82

So there are 57 males and 82 females.
