Answer:
So identifying this problem,3 times 3 is 9.Then 9 divided by 4 equals 2.25.To give you an answer of (2.25+9).
Step-by-step explanation:
Answer:B
Step-by-step explanation:
slope=(y-y0)/(x-x0)
Slope=(5-1)/(5-1)
Slope=4/4
Slope=1
Equation y=mx+c
m=slope
Y=
Answer:
It is the same distance from 0 as the original number
a rational number is any number that can be written as a fraction.
lets say she picked 1/4...the opposite would be -1/4...both are equidistant from 0.
Step-by-step explanation:
Answer:
10 meters
Step-by-step explanation:
The given function 
represents the height, 
, in meters, 
seconds after the ball is thrown.
Since the ball is thrown off the roof, then ball's height will be equal to the roof's height before being thrown (0 seconds). Therefore, substitute 
into the given function :
Therefore, the building is 10 meters tall.
Answer:
99.85%
Step-by-step explanation:
Most of today's student calculators have probability distribution functions built in. Here we are to find the area under the standard normal curve between 58 mph and 76 mph, if the mean speed is 67 mph and the std. dev. is 3 mph.
Here's what I'd type into my calculator:
normalcdf(58, 76, 67, 3)
The result obtained in this manner was 0.9985.
This states that 99.85% of the vehicles clocked were traveling at speeds between 58 mph and 76 mph.
