How many solutions does this equation have? -2-5x= -(5x+2)

Answer:

A is the answer it sounds more likely

For given data, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4.

"If A and B are independent events then, P(A∩B) = P(A).P(B)"

"It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

For given question,

We have been given a table that shows the results broken down by gender.

             Play sports         Do not play sports       Total

Boy            105                            75                        180

Girl             70                             50                        120

Total          175                            125                       300

Using the definition of probability:

⇒ P(girl)  = Number of girls/ Number of students

⇒ P(girl) = 120/300

⇒ P(girl) = 0.4                     ....................(1)

Now we find the probability of girls that play a sport.

Using the definition of probability:

P(girl plays a sport)

= Number of girls who plays a sport/ number of students who plays a sport

= 70/ 175

= 0.4                                    ......................(2)

From (1) and (2),

P(girl) = P(girl plays a sport)

Thus, being a girl and playing a sport are Independent events.

Answer:

y = 2x - 3

Step-by-step explanation:

The negative recipricol is -1/(-1/2) = 2

Use point-slope equation:

y-y1 = m(x-x1)

x1 = 3, y1=3

y-3 = 2(x-3)

y-3 = 2x-6

y = 2x-3

Answer:

Horizontal: if y is equal to 0, then there is no vertical movement

if the number is under 5 like 4,3,2,1 your round down

Step-by-step explanation:

Answer:

To The Nearest Tenth : 1.5

To The Nearest Whole Number : 2

Tip:

If the number is 4 or below like 1.42 it would be rounded to 1.4

Step-by-step explanation:

Answer:

100

Step-by-step explanation:

Answer:

Total population = 340000

Growing rate = 4%

Growing population = 340000×4/100

= 13600 per year

Now population increased in 20 years = 13600 × 20 = 272000 population.

Now ,

The population after 20 years = 340000+272000

=612000

So the population after 20 years = 612000

The expression the represent the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours is total cost = 9b + 10s

The cost of rent for bike and scooters are different.

cost for bike = $9 per hour

cost for scooter = $10 per hour

Therefore, he expression the represent the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours is as follows:
