Answer:
Step-by-step explanation:
The initial value is the value when x = 0.
For x = 0,
It equals to 3 that’s the answer
Suppose the depth of the diver is d at time time t, rate is given by r=12 1/3 ft/ min. The equation representing the depth of the diver at time t will be:
f(t)=200-(12 1/3)t
Therefore the depth of the diver after t=4.5 min will be:
f(4.5)=200-(12 1/3)*4.5
f(4.5)=200-55.5
f(4.5)=144.5 ft
This means that after 4.5 minutes the diver will be 144.5 ft deep.
Let
x----------> the number of students
y---------> the time in minutes
we know that
<span>If the time varies inversely with the number of students
</span>so
y=k/x
for x=3
y=16 min
16=k/3---------> k=48
y=48/x
for x=2
y=48/2-------> y=24 minutes
the answer is
24 minutes
Answer:
A = 10.5%
B = 28.9%
C = 39.5%
D = 18.4%
F = 2.6%
Step-by-step explanation:
Add all the frequencies together = 38
- 4/38 × 100 = 10.5%
- 11/38 × 100 = 28.9%
- 15/38 × 100 = 39.5%
- 7/38 × 100 = 18.4%
- 1/38 × 100 = 2.6%
10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
