Answer:
4.24
Step-by-step explanation:
Use the distance formula
The equation is 2.50÷5=x
2.50÷5=.50
Mrs. Baker paid $2.50 for 5 pounds of bananas
If x=.50 per banana
Then to get the cost of 8 bananas, you would do 8×.50=$4.00
Mrs. Baker paid $4.00 for 8 pounds of bananas
Each banana costs .50 cents per pound
Answer:
(20.532 , 21.468)
Step-by-step explanation:
Enter data into L₁
CL= 0.95
df= 3
Distribution: xbar ~ t₃
Calculator commands (for TI only): [Stat],[TESTS],[TInterval],[Data],(List: L₁),(Freq:1),(C-Level:0.95),[Calculate]
Confidence interval (20.532,21.468)
We can conclude that the true population mean for bags of potatoes labeled 20.0 pounds is between (20.532,21,468) with a 95% confidence level.
Answer:
120 tiny cubes
Step-by-step explanation:
Find the volume of both the tiny cubes and the big cube. Then we will take big volume cube and divide it by tiny cube volume.
So big cube has volume (5/3*4/3*2)=40/9 cm^3
Tiny cube volume is (1/3*1/3*1/3)=1/27 cm^3
(40/9) divided by (1/27)
is the same as 40/9 time 27=40(27)/9=40(3)=120
3/2, or any equivalent
1/2 = 50%
50% x 3 = 150%
1/2 x 3 = 3/2, or 1 1/2 as a mixed number
