c. 4.67
b. 18.0
d. 13.33
Please select the best answer from the choices provided
Answers
Answer:
choice a.) 4.67
Step-by-step explanation:
Using the Z-score table.
We have:
mean u = 40
standard deviation s = 3
for X = 54
Z-score = Z = (X - u)/s = (54 - 40)/3 = 14/3 = 4.6667
P(Z > 4.6667) = 0.000003 very close to 0

You are considering buying two different vehicles. • The first is a van at $20,523, and an estimated annual operating cost of $3200. • The second is a fuel-efficient car at $23,540 and an estimated annual operating cost of $2450. Use these equations to represent the cost (y) of the cars over x years: Y = 20,523 + 3200 X Y = 23,540 + 2450 X
Answers
Answer:
Fill in the following tables, using the equations.
Cost of owning and operating the vehicles
Vehicle 0 1 2 3 4 5 6
Van $20,523 $23,723 $26,923 $30,123 $33,323 $36,523 $39,723
Car $23,540 $25,990 $28,440 $30,890 $33,340 $35,790 $38,240
How much does each vehicle cost initially?
Van costs $20,523Car costs $23,540How much does each cost to operate for one year?
Van costs $3.200Car costs $2,450Which one initially costs less?
VanWhich one will cost less over the six years?
CarWhen do they cost about the same?
year 4: van accumulated costs $33,323 and car accumulated costs = $33,340By calculating the costs over various years, you can determine which vehicle is more cost-effective based on the expected ownership duration. For instance, over 5 years, the fuel-efficient car is cheaper.
To compare the total cost of the van and the fuel-efficient car over time, we will use the given equations:
For the van: Y = $20,523 + $3200XFor the fuel-efficient car: Y = $23,540 + $2450XHere, Y represents the total cost over X years. To determine which vehicle is more cost-effective over a certain period, we need to calculate and compare the costs for various values of X.
Example Calculation:
Suppose we compare the costs for 5 years.
For the van:Y = $20,523 + $3200(5)
Y = $20,523 + $16,000
Y = $36,523For the fuel-efficient car:
Y = $23,540 + $2450(5)
Y = $23,540 + $12,250
Y = $35,790
In this 5-year scenario, the fuel-efficient car is cheaper than the van.
By performing similar calculations for different time periods, you can determine which vehicle is more cost-effective based on your expected ownership duration.

Answers
Answer:
The answer is D.
Step-by-step explanation:
The expression can be used to find the lateral area plus two bases of the cylinder is (D) 9[tex]\Pi[/tex] + 9[tex]\Pi[/tex] + 6[tex]\Pi[/tex](10) [tex]in^2[/tex] .
Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.
The sum of lateral area and the two bases of the cylinder
= lateral area + sum of the area of two bases.
The lateral area = 6[tex]\Pi[/tex](10) [tex]in^2[/tex].
So, The sum of the lateral area and the two bases of the cylinder

farther?
Kilgore, 27.5 miles
Julio: 28.5 miles
Julio: 112.5 miles
Kilgore; 140 miles
Answers
Answer:
kilgore, 140 miles
Step-by-step explanation:
Kilgore drives farther than Julio with a difference of 27.5 miles. Julio drives 112.5 miles while Kilgore drives 140 miles.
To determine who drives farther, we need to calculate the distance driven by Julio and Kilgore.
Julio: Julio drives 2.5 hours at 45 miles per hour. Using the formula distance = speed × time, Julio's distance is 45 miles/hour × 2.5 hours = 112.5 miles.Kilgore: Kilgore drives 4 hours at 35 miles per hour. Applying the same formula, Kilgore's distance is 35 miles/hour × 4 hours = 140 miles.Kilgore drives farther. The difference in the distance is 140 miles - 112.5 miles = 27.5 miles.

It took 4 hours to drive 240. At this rate,how long does it take to drive 90 miles?
Answers
The required time that it takes for 90 miles is 1.5 hour.
What is the difference between average and instantaneous speed?The average speed is calculated for a period of time while instantaneous speed is calculated at certain instant of time. For instantaneous speed and average speed are equal for an object moving with constant speed.
The total distance is given as 240 miles.
And, the time taken is 4 hours.
Now, the speed can be calculated by taking the ratio of the distance and time as below,
Speed = Distance ÷ Time
⇒ Speed = 240 ÷ 4 = 60
Thus, the time taken to drive 90 miles is calculated as,
Time = Distance ÷ Speed
⇒ Time = 90 ÷ 60 = 1.5
Hence, the time taken to cover 90 miles is 1 hour.

In ΔIJK, the measure of ∠K=90°, KJ = 77, IK = 36, and JI = 85. What ratio represents the cosine of ∠I?
Answers
We have been given that in ΔIJK, the measure of ∠K=90°, KJ = 77, IK = 36, and JI = 85. We are asked to find the ratio that represents the cosine of angle I.
First of all, we will draw a right triangle as shown in the attachment.
We know that cosine relates adjacent side of right triangle with hypotenuse.
[tex]\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}[/tex]
We can see that adjacent side to angle I is IK and hypotenuse is IJ.
[tex]\text{cos}(\angle I)=\frac{IK}{IJ}[/tex]
[tex]\text{cos}(\angle I)=\frac{36}{85}[/tex]
Therefore, the ratio of cosine of angle I is [tex]\frac{36}{85}[/tex].

In the U.S., from 2004 - 2015, the correlation coefficient for the relationship
between the size of a cell phone data plan, x, and the number of text
messages sent, y, is r = +0.97. Describe the relationship between the data
plan size and the number of text messages sent in the U.S.
Answers
Answer:
There is a very strong positive correlation between size of a cell phone data plan and the number of text messages sent in the U.S.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
Positive correlation is an association amid two variables in which both variables change in the same direction. A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
The correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y is:
r = +0.97.
The correlation value is very close to +1.
So, we can say that there is a very strong positive correlation between size of a cell phone data plan and the number of text messages sent in the U.S.

The graph of r = 1/ 1-5 sin theta is symmetric about the
Answers
Answer:
A. y-axis only
Step-by-step explanation:
We have the graph of as given below.
It can be seen that passes through the points (0,0), (4,0) and (6,0).
Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.
Hence, the axis of symmetry of is the y-axis only.
The graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.
How to write polar coordinates?It expresses x and y in terms of r and θ:
x = r cos(θ) , y = r sin(θ)
In polar coordinates, the x-axis corresponds to θ = π/2 and the y-axis corresponds to θ = 0 (or θ = π). So to test for symmetry, we need to check whether replacing θ with π - θ (which reflects the graph across the y-axis) or replacing r with -r (which reflects the graph across the origin) gives us the same equation.
If we replace θ with π - θ, we get:
r = 1 / (1 - 5sin(π - θ)) = 1 / (1 + 5sinθ)
This equation is not the same as the original equation, so there is no symmetry about the y-axis.
If we replace r with -r, we get:
-r = 1 / (1 - 5sinθ)
Multiplying both sides by -1, we get:
r = -1 / (1 - 5sinθ)
This equation is also not the same as the original equation, so there is no symmetry about the origin.
However, if we replace θ with π/2 - θ, we get:
r = 1 / (1 - 5sin(π/2 - θ)) = 1 / (1 + 5cosθ)
This equation is the same as the original equation, so the graph is symmetric about the y-axis.
Therefore, the graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.
