Answer:
12.77 miles per hour
Step-by-step explanation:
Step 1
Convert the diameter from inches to feet
Your bike has a wheel diameter of 29 inches.
1 inch = 0.0833 feet
29 inches =
29 × 0.0833 feet
= 2.41667 feet
Step 2
Circumference of the tire = πD
= π × 2.41667 feet
= 7.5921927182 feet
Step 3
The number feet traveled per hour is
148 revolutions per minute × 7.5921927182 feet
= 1123.6445223 feet per minute
60 minutes = 1 hour
Hence,
1123.6445223 × 60 =
67418.671337 feet per hour.
Converting from Feet per hour to Miles per hours
1 mile = 5280 feet
= 67418.671337 feet per hour/5280 feet
= 12.768687753 miles per hour
Approximately = 12.769 miles per hour
The relative frequency for the range 16 - 20 is 0.27.
<h3>What is the frequency of a data set?</h3>
The frequency of a data set refers to the number of times a data or an event is occurring.
From the given information:
Range Number of values
1 - 5 3
6 - 10 1
11 - 15 4
16 - 20 5
21 - 25 2
Total 15
Relative Frequency = Subgroup frequency/ Total frequency
Relative Frequency for the range 16 - 20:
= 4/15
= 0.27

Answer:
x = ± 10
Step-by-step explanation:
Given
x² - 100 = 0 ( add 100 to both sides )
x² = 100 ( take the square root of both sides )
x = ± 
← note plus or minus, hence
x = ± 10
Answer:
(1.5,0)
(.5,0)
Step-by-step explanation:
Quadratic formula below
We first need to move everything to one side of the equation
4x²-8x+3=0
Then plug everything in
(8±√(-8²-4*4*3))/(2*4)
(8±√16)/8
To calculate the ± we need to do when where it's adding and then negative
we have
(8+4)/8=3/2
and hten
(8-4)/8=1/2
