Five juniors and four seniors have applied for two open student council positions. School administrators have decided to pick the two new members randomly. What is the probability that one junior and one senior are chosen for the two positions?a. 0.395 b. 0.444 c. 0.506 d. 0569 e. 0.722
Answer:
The probability that one junior and one senior are chosen for the two positions is 0.556.
Step-by-step explanation:
The information provided is as follows:
Five juniors and four seniors have applied for two open student council positions. School administrators have decided to pick the two new members randomly.There are a total of 9 students who applied for the two open student council positions.
The total number of ways to select two students from 9 is: [tex]{9\choose 2}=\frac{9!}{(9-2)!}=36[/tex]
Compute the probability that one junior and one senior are chosen for the two positions as follows:
[tex]P(\text{1 Junior and 1 Senior})=\frac{5\times 4}{36}=0.556[/tex]
Thus, the probability that one junior and one senior are chosen for the two positions is 0.556.
Maria needs to be at the airport terminal at 15:20. It will take 2 hours to

13:20-30 min= 12:50
Answer:
12:50
Step-by-step explanation:
If it takes 2 hours to get there, you subtract 2 hours from 15:20 which gives you 13:20. It also says that she needs 30 minutes to park so you subtract that from 13:20 giving you 12:50

What is the absolute value of the number indicated on the number line?
A. -1 3/7
B. 1 1/3
C. -1 1/3
D. 1 3/7
Answer:
1 and 1/3
Step-by-step explanation:
The absolute value means that you have a positive sign no matter what the value is. It is the distance in units from 0 on the number line to the point in question.
The number line is laid out in 1/6. Each tick is 1/6. Since the point is at 1 and 2/6, we have to reduce the fraction. In 2/6 you can divide the bottom and top by 2 to reduce the fraction.
2 divided by 2 = 1
6 divided by 2 = 3
Therefore the 2/6 reduces to 1/3
You already know you had a 1, so you add 1/3 and it is 1 1/3.

c) Parbati buys a mobile for Rs 6,300 and sells it to Laxmi at 15% profit. How much
does Laxmi pay for it?
Answer:
Rs. 7245
Step-by-step explanation:
Given parameters:
Cost price = Rs. 6300
Percentage profit = 15%
Unknown:
Selling price = ?
Solution:
If profit is made on a trade, the selling price is higher than the cost price.
Profit = Selling price - Cost price
To find the selling price simply;
Selling price =( 1 + [tex]\frac{15}{100}[/tex]) x cost price
Selling price = 1.15 x 6300 = Rs. 7245

Nebi has already typed 250 words. He then starts a timer and finds that he types 150 words in 3 minutes. If nebi types at a constant rate, write a linear equation to represent the number of words w that nebi types m minutes after starting the timer
Answer:
[tex]w=250+50m[/tex]
Step-by-step explanation:
Number words Nebi has typed = 250
t = Duration of typing = 3 minutes
Number of words typed in 3 minutes = 150
Rate of typing in 3 minutes
[tex]\dfrac{150}{3}=50\ \text{words/minute}[/tex]
So the linear equation representing the situation would be
[tex]w=250+50m[/tex]
Where
w = Number of words
m = Number of minutes after starting the timer
The linear equation to represent the number of words w that nebi types m minutes after starting the timer is w = 250 + 50m
Given:
Words already typed = 250 words.
Words typed in 3 minutes = 150 words
Words typed per minute = 150 words / 3 minutes
= 50 words per minute
w = Total words typed
m = number of minutes
The equation:
Total words typed = Words already typed + (Words typed per minute × number of minutes )
w = 250 + (50 × m)
w = 250 + 50m
Therefore, linear equation to represent the number of words w that nebi types m minutes after starting the timer is w = 250 + 50m
