Answer:
t < 1.5
Step-by-step explanation:
Mon-Thu: 5.5 hours
each of the remaining 3 days: t hours each day
total time: 3t + 5.5
The total time must be less than 10 hours.
3t + 5.5 < 10
3t < 4.5
t < 1.5
Answer:
(a) x = 260.52
(b) x = 249.24
(c) x = 265.22
(d) x = 297.65
Step-by-step explanation:
Here,
Mean = 
= 300
Standard deviation = 
= 47
(a)
Using standard normal table,
P(Z > z) = 80%
1 - P(Z < z) = 0.8
P(Z < z) = 1 - 0.8
P(Z < -0.52) = 0.2
z = -0.84
Using z-score formula,
x = z × σ + μ
x = -0.84 × 47 + 300 = 260.52
(b) Using standard normal table,
P(Z < z) = 14%
P(Z < -1.08) = 0.1
4
z = -1.08
Using z-score formula,
x = z × σ + μ
x = -1.08 × 47 + 300 = 249.24
(c)
Using standard normal table,
P(Z < z) = 23%
P(Z < -0.74) = 0.243
z = -0.714
Using z-score formula,
x = z × σ + μ
x = -0.74 × 47 + 300 = 265.22
(d) Using standard normal table,
P(Z > z) = 52%
1 - P(Z < z) = 0.52
P(Z < z) = 1 - 0.52
P(Z < -0.25) = 0.4
8
z = -0.05
Using z-score formula,
x = z × σ + μ
x = -0.05 × 47 + 300 = 297.65
Answer:
Step-by-step explanation:
In Excel to create chart, you would have create a data
For instance:
Male Female
year 1 45 60
year 2 18 12
year 3 43 72
year 4 44 40
year 5 23 56
After this, select the whole data and click on "insert" on the "menu bar"
and click on the "recommended charts" to select or choose the best fits (e.g. bar, pie, histogram etc).
Answer:
1. y = 10(1/3)^x
2. 24.8 bacteria per minute
Step-by-step explanation:
1.
When you raise a number between 0 and 1 to a positive exponent, the result is less than 1, so it indicates exponential decay.
The only such function in the choices is
Answer: y = 10(1/3)^x
2.
b(t) = 4(2)^t
b(0) = 4(2)^0 = 4
b(5) = 4(2)^5 = 128
average rate of change = (128 - 4)/(5 - 0) = 124/5 = 24.8
Answer: 24.8 bacteria per minute
