The possibility is 48/200
The probability of people preferred the new soft drink is 6/25.
To find the probability.
What is probability?probability is the ratio of the number of favorable outcomes and the total number of possible outcomes.
Given that:
Total number of people taste test=200
Number of people who participated new soft drink=48
Number of people who participated old soft drink=112
Number of people who participated could not tell any difference=40
So, the probability of people preferred the new soft drink=
favorable outcome/total number of outcome
probability of people preferred the new soft drink=48/200
probability of people preferred the new soft drink=6/25
So, the probability of people preferred the new soft drink is 6/25.

find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-1/2x-4
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
Plzzzz Find the value of x
Answer:
the answer is 55
Step-by-step explanation:
x + x + 90 = 180
2x + 90 = 180
2x = 180- 90 = 110
x = 110 ÷ 2 = 55

A,B,C,D
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
How to find the expression for total cost?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:

Are being a girl and playing a sport Independent events? Why or why not?
O A. Yes, they are independent, because P(girl) = 0.58 and Pgirl plays
a sport) = 0.6.
O B. Yes, they are independent, because (girl) = 0.42 and girl plays
a sport) - 0.42
O c. No, they are not independent, because P(girl) = 0.42 and
P(girl plays a sport) = 0.42.
D. Yes, they are independent, because (girl) = 0.58 and P(girl plays
a sport) = 0.58
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.
What are independent events?"These are the events whose occurrence is not dependent on any other event.""When the probability of occurrence of an event A is not affected by the occurrence of another event B, then event A and event B are independent events."Formula for probability of independent events:"If A and B are independent events then, P(A∩B) = P(A).P(B)"
What is probability?"It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is: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.

Suppose a city with population 340,000 has been growing at a rate of 4% per year. If this rate continues, find the population of this city in 20 years.
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

Answer:
[tex](x-5)^{2} + (y+7)^{2} = 49[/tex]
Step-by-step explanation:
9514 1404 393
Answer:
(x -5)^2 +(y +7)^2 = 49
Step-by-step explanation:
The equation of the circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
Putting (h, k) = (5, -7) and r = 7 into this form, your equation is ...
(x -5)^2 +(y +7)^2 = 49
