Answer:
785.398 ft
Step-by-step explanation:
Circumfrence = pi * diameter
The first windsurfer is travelling faster. Solution:
1 meter = 3.28084 feet
The first surfer travels at 5 meters/second so you have to multiply 3.28084 by 5 which equals 16.4042 ft/second
There are 60 seconds in a minute so you will have to multiple 16.4042 ft/second by 60 seconds which equals 984.252 ft/minute
984.252 ft/minute > 720 ft/minute
Answer:
y = -2x + 6
Step-by-step explanation:
y=mx + c
m is the gradient and c is the y intercept
m = (y 2 - y 1) / (x 2 - x 1) = (2-4) / ( 2-1) = -2
y= -2x + c
To find c, just sub one of the coordinates into the eqn:
By using the coordinates (1,4)
4 = -2(1) + c
c = 6
Therefore, the equation is y = -2x + 6

Answer:
b. 2.28%.
Step-by-step explanation:
Mean temperatue (μ) = 1000°F
Standard Deviation (σ) = 50
°F
For any temperature value, X, the z-score is given by:
For X= 900°F
A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:
