Oceanside Bike Rental Shop charges a eleven dollar fixed fee plus nine dollars an hour for renting a bike. Melanie paid sixty - five dollars to rent a bike. How many hours did she pay to have the bike checked out? Let h represent the number of hours.
Answer:
She paid 6 hours for the bike to be checked out
Step-by-step explanation:
1. The equation is 11+9h=65. 11 represents the start value (fixed fee) and 9h represents how many hours she paid for, which is $65.
2. You subtract 11 from 65 to start figuring out how many hours she paid for. 65-11=54
3. You then divide 54 by 9 to calculate how many hours she paid. 6

What is the median of 51 67 63 52 49 48 48?
Answer:
51
Step-by-step explanation:
Given;
51,67,63,52,49,48,48
Solve;
Order from least to greatest
48, 48, 49, 51, 52, 63, 67
Steps to find median;
Arrange data values from lowest to highest valueThe median is the data value in the middle of the setIf there are 2 data values in the middle the median is the mean of those 2 values.48, 48, 49, 51, 52, 63, 67
48, 48, 49, 51, 52, 63, 67

Kieran’s wallet contains 7 bills: three $5 bills, two $10 bills, one $20 bill, and one $100 bill. If Kieran pulls out two bills at random, what is the probability that he selects exactly two $5 bills? Use complete sentences to explain the probability. In your final answer, include all of your calculations.
Answer:
Exact probability = 1/7
(Approximate probability = 0.142857)
========================================================
Explanation:
There are three 5 dollar bills out of 7 total. The probability of selecting a five dollar bill is 3/7. Let A = 3/7 since we'll use it later.
After the first selection is made, we have 3-1 = 2 five dollar bills left out of 7-1 = 6 bills overall. This is assuming we do not put the first selection back, or replace it with another five dollar bill.
The probability of selecting another five dollar bill is 2/6 = 1/3. Let B = 1/3.
Multiply the values of A and B to get
A*B = (3/7)*(1/3) = (3*1)/(7*3)= 1/7
Note the 3's divide and cancel out.
Using a calculator, 1/7 = 0.142857 approximately
Answer:
1/7
Step-by-step explanation:
$5 = 3, $10= 2, $20= 1, $100= 1- total 7 bills
Probability of getting $5 bill is 3/7Probability of getting second $5 bill is 2/6= 1/3 as one of $5 bill already taken and total number of bills reduced to 6Probability of getting 2 of $5 bills is the product of individual probabilities: 3/7*1/3= 1/7Answer is 1/7

9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Which of these is the best estimate for 275% of 40 ?
greater than 0 but less than 1
greater than 1 but less than 2
greater than 2 but less than 3
greater than 3
Use pencil and paper. Explain the reasoning behind your choice.
Question content area bottom
Part 1
275% of 40 is :
Answer: 110
Step-by-step explanation: Write 275% as
275
100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
275
100
of 40 =
275
100
× 40
Therefore, the answer is 110
If you are using a calculator, simply enter 275÷100×40 which will give you 110 as the answer.

Answer:
1) Yes, table shows a probability distribution
2) Mean = 1.5
3) Standard Deviation = 1.1
Step-by-step explanation:
PART 1:
For the table to show a probability distribution, the sum of all probabilities should be equal to 1
Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025
Sum of probabilities = 1
Hence, the table shows the probability distribution.
PART 2:
The formula for mean is given by:
Mean = Sum of terms/ Total no. of terms
Mean = (0+1+2+3) / 4
Mean = 1.5
PART 3:
The formula for standard deviation is given by:
\(\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}\)
Solve using a calculator, we get
σ = 1.118

The minute hand on a clock is 15cm long. what area does it pass over in 1 hour (pls show working)
Answer:
the 12 on the clock
Step-by-step explanation:
Answer:
94.2cm in 1 hour.
Step-by-step explanation:
In 1 hour, minute hand completes one round means makes a circle.
Radius of the circle(r)=15cm
Circumference of circular clock=2πr
=2×3.14×15=94.2cm
Therefore, the tip of the minute hand moves 94.2cm in 1 hour.
Which of the following show a percent increase greater than 50%? Select all that apply.?
A jacket that costs $18 is sold to the customer for $25.
A hat that costs $8 is sold to the customer for $12.
A pair of shoes that costs $20 is sold to the customer for $35.
A shirt that costs $12 is sold to the customer for $20
Answer: A pair of shoes that costs $20 is sold to the customer for $35, and A shirt that costs $12 is sold to the customer for $20.
Step-by-step explanation:
1. Half (or 50%) of 20 is 10, so 20+10=30, but 35 is bigger than 30.
2. Half (or 50%) of 12 is 6, so 12+8=18, but 20 is bigger than 18.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.
Step-by-step explanation:

Answer:
x = 3(-8)
Step-by-step explanation:
Answer:
\(x=39\)
Step-by-step explanation:
\(-2\left(x+5\right)-4+3\left(x-8\right)=1\)
Add 4 to both sides:
\(-2\left(x+5\right)-4+3\left(x-8\right)+4=1+4\)
\(-2\left(x+5\right)+3\left(x-8\right)=5\)
Expand:
\(-2x-10+3\left(x-8\right)=5\)
\(-2x-10+3x-24=5\)
\(x-34=5\)
Add 34 to both sides:
\(x-34+34=5+34\)
\(x=39\)
