The total time spent on his/her cell phone in a year’s time is less than the total time spent waiting in line when shopping in a lifetime.
x= 1825 hrs
z=4929.4 hrs.
This is further explained below.
Which amount of time is greater for the average person?let's say on average a person spends 5 hours on a mobile phone.
Individual annual mobile phone use time.
x= 5x365
x= 1825 hrs
let's consider an average every day a person, spent 5 minutes in the queue when shopping.
Take the average person. 70-year life for a person.
Hence in a year, he spent
y=365x5 mints
y=1825 min
y=30.42 hrs
Hence lifetime time spent on line
z = 70 x 30.42
z=4929.4 hrs.
In conclusion, we estimate that the typical individual will spend z=4929.4 hours waiting in line for merchandise throughout the course of their lifetime.

Volume and surface area
By applying the volume formulae for composite figures, cones and hemispheres, we obtain that the volume is approximately equal to 558.9 cubic centimeters.
How to determine the volume of a composite figure
The volume of the composite figure is the sum of the volumes of the two figures: (i) a cone, (ii) a hemisphere. The volume formula of the figure is shown below:
[tex]V = \frac{2\pi}{3} \cdot r^{3} + \frac{\pi}{3}\cdot r^{2}\cdot h[/tex]
If we know that r = 5.3 cm and h = 8.4 cm, then the volume of the composite figure is:
V = (2π/3) · (5.3 cm)³ + (π/3) · (5.3 cm)² · (8.4 cm)
V ≈ 558.900 cm³

Consider the problem: Jasmine wants to buy a brand new pair of headphones that cost $99. While she already has $40 saved up, she is planning on working at a local grocery store for $8 an hour to make up the extra cash. Which of the following inequalities will help her determine values of h, the number of hours that Jasmine can work so she can afford the new headphones?
The number of hours that Jasmine can work so she can afford the new headphones x = 6 weeks.
let x represent the number of weeks it will take to save enough money.
If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have
11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.
Subtract 107 from both sides to get
11x = 66
Divide both sides by 11 to get
x = 6 weeks.

The graph of f(x)=x2 is shown. Use the parabola tool to graph the function g(x)=(15x)2 . To graph a parabola, first plot the vertex then plot another point on the parabola
The graph of the parabola can be seen in the image below.
How to plot the parabola?Here we have the function:
g(x) = (15x)^2
Notice that this is a contraction of scale factor 15 of the function f(x) = x^2
To graph this, we can just evaluate the function in 3 points, the vertex and two other ones.
for x = 0.
g(0) = (15*0)^2 = 0
So we have the point (0, 0).
Evaluating in x = 1 and x = -1 (give the same value) we get:
g(±1) = (±15)^2 = 225
So we have the points (1, 225) and (-1, 225).

What is the probability that a random sample of 10 second grade students from the city results in a mean reading rate of more than 96 words per minute
Using the normal distribution, it is found that there is a 0.1029 = 10.29% probability that the sample mean is above 96.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].Researching the problem on the internet, the parameters are given as follows:
[tex]\mu = 92, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]
The probability that the sample mean is above 96 is one subtracted by the p-value of Z when X = 96, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{96 - 92}{3.1623}[/tex]
Z = 1.265
Z = 1.265 has a p-value of 0.8971.
1 - 0.8971 = 0.1029 = 10.29% probability that the sample mean is above 96.

Assuming you are a business owner with different shareholders. How may zero growth stock valuation and constant stock valuation affect your business operations?
The ways that zero growth stock valuation can affect business operations is that:
When zero-growth model states that the dividend is at the same rate, it shows that one has no measure of growth in terms of dividends. This therefore shows that stock price is equal to the annual dividends and divided also by the needed rate of return.What ways does constant stock valuation affect business operations?The Constant stock valuation is known to be a kind of share evaluation as it states that the dividends paid by a firm will consistently increase at a constant growth rate.
This will help one to know especially investors on how to set or know the fair price that one needs to pay for a stock on daily basis today by due to future dividend payments.

How to calculate the height?From the information given, the tower is 45m, the clinometer is set at 1.3m above the ground, and the angle of elevation is 32°.
This can be illustrated as:
tan 32° = (45 - 1.3)/x
tan 32° = 43.7/x
x = 43.7/tan 32°
x = 69.93m.
Also, for triangle ACD,
tan 47° = (43.7 + y)/x
x × tan 47° = 43.7 + y

65 people took a clarinet exam. Before the exam, 23 people predicted that they would pass, and the rest predicted they would fail. Of the people who predicted they would pass, 18 actually did. In total, 31 people passed the clarinet exam. What fraction of those who thought that they would fail actually did fail?
Answer:
The answer is 29/42
Step-by-step explanation:
First, let's calculate how many people predicted they would fail. The question states that 65 people took the exam and 23 predicted they would pass, so we can find the number of people that predicted they would fail by the following calculation:
Let FP be the people who predicted they'd fail
65 = 23 + FP
65 - 23 = FP
42 = FP
Now, let's move on to the next part. The question states that a total of 31 people passed the test, from those 18 being the people who predicted they would pass and the rest are people who had predicted they would fail but ended up passing.
Let's set x as the number of people who predicted they would fail but have passed.
31 = 18 + x
31 - 18 = x
13 = x
Since 13 of the 42 FP have passed, we can calculate how many of them failed. Let y be the number of people that predicted to fail and ended up failing:
13 + y = 42
y = 42 - 13
y = 29
Finally, now we have the fraction of those who predicted that they would fail actually did fail and that's 29/42

The value of the house in the year 2010 is 150056.47.
What is growth rate?The growth rate of a value (GDP, turnover, wages, etc.) measures its change from one period to another (month, quarter, year)
Value
v(t) = V0 ( 1 + r)^t
let V0 = 106, v(20) = 146
So,
146 = 110(1 + r )^20
146/110 = (1 + r )^20
1.327 = (1 + r )^20
1+ r = 1.014
