Step-by-step explanation:
Timmy is building a new website. Right after he starts, he has 2 visitors. He expects his visitors to increase according to a model he developed for his other websites growth, v(t)=10t+b, where b is the number of visitors right afte he starts building his website, t is the time since he stgarted building his website in weeks and v(t) is the nunber of total visitors after t weeks.
How many visitors does he get 4 weeks after starting to build his website?
How any new visitors does he get per week?
Answer:
He gets 42 visitors 4 weeks after starting to build his website.
He gets 10 new visitors per week.
Step-by-step explanation:
Equation for the number of visitors:
The equation for the number of visitors Timmy's new website receives after t weeks is:
[tex]v(t) = 10t + b[/tex]
In which b is the number of visitors rightly after he starts.
Timmy is building a new website. Right after he starts, he has 2 visitors.
This means that [tex]b = 2[/tex], so:
[tex]v(t) = 10t + 2[/tex]
How many visitors does he get 4 weeks after starting to build his website?
This is v(4). So
[tex]v(4) = 10(4) + 2 = 40 + 2 = 42[/tex]
He gets 42 visitors 4 weeks after starting to build his website.
How any new visitors does he get per week?
After 0 weeks:
[tex]v(0) = 10(0) + 2 = 0 + 2 = 2[/tex]
After 1 week:
[tex]v(1) = 10(1) + 2 = 10 + 2 = 12[/tex]
2 weeks:
After 2 week:
[tex]v(2) = 10(2) + 2 = 20 + 2 = 22[/tex]
22 - 12 = 12 - 2 = 10
He gets 10 new visitors per week.

Which of the following is always one of the data values in a data set?
Answer:
mean
Step-by-step explanation:
1. The mean is always one of the data values. 3. The mode is always one of the data values.
Answer: The mode.
Step-by-step explanation: The answer to this question is the mode, the answer is mode because there might be some numbers that show up the same amount of times like a different number. So there might be TWO modes :’).
Here are the definitions for mean, median, mode, and range:
Mean (the “average”) —> the sum of the numbers in the data set divided by the amount of numbers in the data set.
Median (the “middle”) —> the number in the middle of the data set, when the numbers are placed in numerical order.
Mode (the “most”) —> the number in the data set that shows up the most often.
Range —> the difference between the data set’s largest number and the data set’s smallest number.

1) 14 units2 2) 16 units2 3) 17 units2 4) 19 units2
Answer:
4th option: 19 units2Step-by-step explanation:
The given figure can be divided as (i) upper rectangle, (ii) lower rectangleThen,
(i) Breadth of upper rectangle = 2 units
Length of upper rectangle = 8 - 1 = 7 units
Therefore,
Area of the upper rectangle = 7 × 2 = 14 units2
(ii) Breadth of lower rectangle = 1 unit
Length of lower rectangle = 5 units
Therefore,
Area of the lower rectangle = 5 × 1 = 5 units2
Since,
Area of the figure is = Area of upper rectangle + Area of lower rectangle
= 14 units2 + 5 units2
= 19 units2 (Ans) (4th option)
6 in every 18 people have never flown on a plane. What is the ratio of people that have flown in a plane to all people?
Answer:
1:3
Step-by-step explanation:
Divide both numbers by the same value to get the ratio
6/6=1
18/6=3
To get the smallest numbers you can get by dividing using the same value
So the ratio would be 1:3

In a survey of 802 U.S. adult drivers, 265 state that traffic is getting worse in their community. Construct a 95% confidence interval for the proportion of residents who think traffic is getting worse in their community.
Answer:
The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
In a survey of 802 U.S. adult drivers, 265 state that traffic is getting worse in their community.
This means that [tex]n = 802, \pi = \frac{265}{802} = 0.3304[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 - 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.2978[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3304 + 1.96\sqrt{\frac{0.3304*0.6669}{802}} = 0.3630[/tex]
The 95% confidence interval for the proportion of residents who think traffic is getting worse in their community is (0.2978, 0.3630).

10. What is the solution of the system of equations graphed below?*
Answer:
No solution
Step-by-step explanation:
Unfortunately your screenshot has cut off the final answer choice, if it says "no solution" you should choose that because these two lines are parallel. Meaning they will never intersect, and the point of intersection is usually the solution.

A ball is tossed into the air. The quadratic function h(t) = -16t^2 + 14t + 5 represents the situation, where t represents the time, in seconds, after the ball is tossed and h(t) represents the height of the ball, in feet. Which of the following statements is NOT true
A- the constant term represents the height from which the ball was tossed.
B- The factors of the function can help determine when the ball hit the ground.
C- The leading coefficient indicates that the graph of the parabola that represents the ball's height over time will open in an upward direction.
D- The graph of the parabola that represents the ball's height over time will have a relative maximum.
The probability that a birth in the United States is male during 2018 is 0.511. Suppose a random number generator from 1 to 1,000 is used as a statistical model to create simulated results for births in the United States during 2018. Suppose the numbers 1 to 511 represent a male birth in the United States during 2018 and 512 to 1,000 represent a female birth in the United States during 2018. Explain whether the following results are consistent with the model, and if not, explain the expected number of male births and the expected number of female births for 300
trials.
In 300
simulated trials, 171 of the births are female and 129 are male.
Answer:
Step-by-step explanation:
The probability that a birth in the United States is male during 2018 is 0.511. So there are slightly more males than females born.
In 300 simulated trials, 171 of the births are female and 129 are male. More females are born so it is not consistent with the model.
The expected number of male birth for 300 trials should be 300*0.511 = 153.
The expected number of female = 300-153 = 147

9514 1404 393
Answer:
735.6 in³
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = 4/3πr³ . . . . where r is the radius
The radius is half the diameter, so we can write this in terms of diameter as ...
V = (4/3)π(d/2)³ = (π/6)d³
Using the given diameter, the volume is ...
V = (π/6)(11.2 in)³ ≈ 735.6186 in³
The volume is about 735.6 cubic inches.

how is y=2x^2-8x+9 rewritten in vertex form.
9514 1404 393
Answer:
y = 2(x -2)^2 +1
Step-by-step explanation:
Start by factoring the leading coefficient from the x-terms.
y = 2(x^2 -4x) +9
Now identify the coefficient of x, -4, and figure half of that: -2. Square this number and add it inside the parentheses. At the same time, subtract the equivalent value outside parentheses. (The leading coefficient must be taken into account.)
y = 2(x^2 -4x +4) +9 -2(4)
Put in the desired form.
y = 2(x -2)^2 +1
This matches vertex form ...
y = a(x -h)^2 +k . . . . . . . . . vertical scale factor 'a'; vertex (h, k)
