Answer:
a) distance traveled is 16 miles.
b) distance traveled is 40 miles.
Step-by-step explanation:
Speed is a scalar quantity which describe the rate of distance moved with time.
i.e speed =
Given that: distance = 2 1/3 miles = miles, time = 3 1/2 minutes = minutes.
Then;
speed = ÷
= x
=
The car's steady speed is 0.67 miles per minute.
a) when the time is 24 minutes, the distance covered can be determine by:
distance = speed x time
= x 24
= 16
distance traveled is 16 miles.
b) When the time is 1 hour (60 minutes), the distance traveled can be determined by:
distance = speed x time
= x 60
= 40
distance traveled is 40 miles.

Answer:
B. Yuri divided by n instead of n-1
Step-by-step explanation:
It was stated in the question that the dataset was sample dataset. For a sample dataset, the standard deviation is given by the formula,
σ = √ Σ (Xi - mean)²/(n - 1) where i = 1,2,3.....n
Since this is just a sample dataset and not the whole population, Yuri should have divided by n-1 instead of n.
Answer:
3 3/4
Step-by-step explanation:
Each block is worth 0.5 cm (1/2)
One note - NEVER FORGET THE UNITS
L - 5 blocks (5 blocks × 0.5cm = 2.5cm)
W - 2 blocks (2 blocks × 0.5cm = 1cm)
H - 3 blocks (3 blocks × 0.5cm = 1.5cm)
Formula for Volume:
V = L × W × H
V = 2.5cm × 1cm × 1.5cm = 3.75cm (fraction can be 3 3/4)
You're welcome :)
