Answer:
1. 80
2. 80
3. 40
Step-by-step explanation:
The question requires us to Use the sample size of 200 to find the expected frequency for categories A, B and C
1. (Category proportion)(sample size)
eA = 0.40x200
= 80
2. (Category proportion)(sample size)
eB = 0.40x200
= 80
3. (Category proportion)(sample size)
eC = 0.20 x 200
= 40
The answers are 80, 80 and 40 respectively.
Answer:
To write 8000 miles in scientific notation, first find a natural number between 1 and 10. (8)
Now, figure out how many decimal places we have to move to the left.
8000.0 --> 8.0000 (Three
)
Now, write the number 8 multiplied by 10 to the third power.
( 8 × 10^3 miles )
Step-by-step explanation:
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
Answer:
200
Step-by-step explanation:
You have to divide 300 by 1.50 which gives you 200.
Answer: 48 square units
Step-by-step explanation:
8 * 12 = 96
The square is 96 square units.
6 * 8 = 48/2 = 24
24 is the shaded region of 1 of the triangles.
24 * 2 = 48.
The total shaded region is 48 square units.
