According to a survey conducted by Deloitte in 2017, 0.4702 of U.S. smartphone owners have made an effort to limit their phone use in the past. In a sample of 54 randomly selected U.S. smartphone owners, what is the probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past?
1) 0.0241.
2) 0.1703.
3) 0.8779.
4) 0.0483.
5) 0.1221.
Answers
Answer: 0.628
Step-by-step explanation:
Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702
Sample size : n= 54
Mean : [tex]\mu =(54)(0.4702)=25.39[/tex]
Standard deviation:
[tex]\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039[/tex]
The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :
[tex]P(22\leq x\leq29)=P(21<x<30)=P(\dfrac{21-25.39}{5.039}<\dfrac{X-\mu}{\sigma}<\dfrac{30-25.39}{5.039})\\\\=P(-0.8712<z<0.914864)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\=P(z<0.914864)-P(z<-0.8712)\\\\=P(z<0.914864)-(1-P(z<0.8712))\\\\=0.8198685-(1-0.8081775)\ \ \ [\text{ By p-value table}]\\\\=0.628046[/tex]
Hence, the required probability = 0.628

A scientist started with a culture of 10 bacteria in a dish. The number of bacteria at the end of each successive minute increased exponentially, so that the number at the end of one hour was 500. How many hours (to the nearest hour) from the start of the experiment passed before there were 1,000,000 bacteria?
Answers
Answer: 3 hours
Step-by-step explanation: Exponential growth is a model showing a specific quantity increasing over time.
The formula for it is [tex]y(t)=A_{0}e^{kt}[/tex]
in which
y(t) is the quantity after time t
A₀ is initial value
k is rate of growth
t is time
To determine how much time has passed, first find the rate of growth and knowing that 1 hour has 60 minutes:
[tex]500=10e^{60k}[/tex]
[tex]e^{60k}=50[/tex]
[tex]60k=ln(50)[/tex]
k = 0.065
With the rate, determine the time
[tex]10^{6}=10e^{0.065t}[/tex]
[tex]e^{0.065}=10^{5}[/tex]
[tex]0.065t=5ln(10)[/tex]
t = 177.12 minutes
The amount of hours passed is
[tex]t=\frac{177.123}{60}[/tex]
t = 3
From the start of the experiment, it has passed 3 hours before there were 1,000,000 bacterias.

The half-life of cesium-137 is 30 years. Suppose we have a 20 mg sample.
a. Find the mass (in mg) that remains after t years.
b. How much of the sample (in mg) remains after 20 years?
c. After how long will only 1 mg remain?
Answers
Answer:
(a) A = (20mg)/(2^(t/30))
(b) 12.6mg
(c) 129.6years
Step-by-step explanation:
To calculate the amount remaining after a number of half-lives, n, we can make use of:
[tex]A = \frac{B}{2^n}[/tex]
Where A = amount remaining
B = initial amount
[tex]n = \frac{t}{t_{0.5}}[/tex]
(a) A = (20mg)/(2^(t/30))
(b) Mass after 20years
A = (20mg)/(2^(20/30)) ≈ 12.6mg
(c) After how long will only 1mg remain:
1mg = (20mg)/(2^(t/30))
[tex]20mg = {2^{\frac{t}{30}}[/tex]
Taking log of both sides we have:
Log(20) = (t/30)log(2)
t/30 = (log(20))/(log(2)) ≈ 4.3
t/30 = 4.3
t = 30 x 4.3 ≈ 129.6years.

( please explain it to me!) 7. Wei's mark on a test was 39. This
mark was 60%. What was the total
possible mark?
Answers
Answer:
65
Step-by-step explanation:
Since 39 is equal to 60%, and 60% is also equal to 60/100, then 39/x (x is the total we are solving for) is equal to 60/100.
Cross multiply so 39/x = 60/100
39*100 = 60x
3900 = 60x (divide both sides by 60)
65 = x
Choose the equation that represents the asymptote of the graph f(x) = 2^x +3.
y = 0
y = 3
x = 0
x = 3
Answers
Answer:
x = 0Step-by-step explanation:
The horizontal asymptote occurs at x = 0, Hence the equation that represents the asymptote of the graph is at x = 0
f(x) = 2^x +3.
0 = 2^x +3.
2^x +3. = 0
2^x = -3
log 2^ x = log(-3)
x log2 = log(-3)
x = log(-3)/log 2
Hence the required function is when x = 0
