P( Take the bus | Junior) = [?]
Round to the nearest hundredth.
Answers
===================================================
Explanation:
The notation
P( Take the bus | Junior)
is the same as writing
P( Take the bus given Junior)
I replaced the vertical bar with the word "given".
Since we're given that the person is a Junior, this means we only focus on the Juniors. There are 13+20+2 = 35 Juniors and 20 of them take the bus.
20/35 = 0.5714 approximately which rounds to 0.57
This says about 57% of the Juniors take the bus.
The probability of P(take the bus/Juniors) is 0.57 or in percentage is 57%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
We have to find the probability of who take the bus and they are juniors
P(take the bus/Juniors)
From the table, let us find the total number of juniors
Among juniors 13 students drive to school, 20 takes the bus and 2 come by walk
Total Juniors = 13+20+2
=35
P(take the bus/Juniors) = 20/35
Divide twenty by thirty five
=0.57
Hence, the probability of P(take the bus/Juniors) is 0.57 or 57%.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 4 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.

Samir works in a department store selling clothing. He makes a guaranteed salary of $300 per week, but is paid a commision on top of his base salary equal to 15% of his total sales for the week. How much would Samir make in a week in which he made $1275 in sales? How much would Samir make in a week if he made xx dollars in sales?
Answers
Answer:
$491.25 and 0.15xx + 300
Step-by-step explanation:
15%=0.15
$1275×0.15=$191.25 in sales
$191.25+$300=$491.25
He would make $491.25 a week in which he made 1275 in sales.
0.15xx + 300 = total earnings
He would make 0.15xx + 300 if he made xx dollars in sales

Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Answers
Answer:
Step-by-step explanation:
Image result for Guadalupe went shopping for a new pair of pants. Sales tax where she lives is 7%. The price of the pair of pants is $33. Find the total price including tax. Round to the nearest cent.
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.
The price of the pants after tax is $35.31
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Price of the pants before tax= $33 and tax rate as 7%
Thus 7% of 33=2.31
Thus price after tax is equal to $33+$2.31=$35.31
Hence, The price of the pants after tax is $35.31
