Answer:
a. 5
b. 545
c. 0
Step-by-step explanation:
These are straightforward division problems, easily solved using your own memorized multiplication facts, or using a calculator.
a. 20 ÷ 4 = 5 means 5 × 4 = 20
b. 2725 ÷ 5 = 545 means 545 × 5 = 2725
c. 0 ÷ 5 = 0 means 0 × 5 = 0
_____
When using the Google calculator and standard keyboard symbols, you can use the slash (/) for "divided by" and the asterisk (*) for "times."

Answer:
133 1/3 km/hour
Step-by-step explanation:
Average speed is computed as ...
average speed = (total distance)/(total time)
= (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)
= 133 1/3 km/hour
95% confidence interval is given by
x - 2D , and x+ 2D
For 99% confidence interval is
x - 3D , and x + 3D
x = 100000
D = 2000
Then calculate
100000 - 3•2000= 94000
and
100000 + 3•2000= 106000
Now find √D = 44.72
Then interval is
100000 - 44.72 ,. And. 100000 + 44.72
99,956 lower limit and. 100472 upper limit
Then we see that theres only one interval ,
that is between thes 2 limits
ANSWER Is OPTION C) ) ($99.996.46, $100,003.55)
To calculate slope; rise/run
Triangle ABC: run-1 rise-5 slope-5
5 rise/ 1 run (5/1)=5
Triangle DEF: run-2 rise 10 slope-5
10 rise/ 2 run (10/2)=5
B. They are equal because the two triangles are similar
