A baseball rolls off a 1.20 m high desk and strikes the floor 0.50m away from the base of the desk. how fast was the ball rolling?
Answer:
1.01 m/s
Step-by-step explanation:
a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
t = Time
[tex]s_y[/tex] = Displacement in y direction = 1.2 m
[tex]s_x[/tex] = Displacement in x direction = 0.5 m
[tex]v_x[/tex] = Velocity in x direction
Displacement in y direction is given by
[tex]s_y=u_yt+\dfrac{1}{2}at^2\\\Rightarrow t=\sqrt{\dfrac{2s_y}{a}}\\\Rightarrow t=\sqrt{\dfrac{2\times 1.2}{9.81}\\\Rightarrow t=0.4946\ \text{s}[/tex]
[tex]s_x=v_xt\\\Rightarrow v_x=\dfrac{s_x}{t}\\\Rightarrow v_x=\dfrac{0.5}{0.4946}\\\Rightarrow v_x=1.01\ \text{m/s}[/tex]
The ball was rolling with a speed of 1.01 m/s.

A particularly long traffic light on your morning commute is green 17% of the time that you approach it. Assume that each morning represents an independent trial. Over 20 mornings, what is the probability that the light is green on exactly 4 day
Answer:
Step-by-step explanation:
Assuming that we are only trying to calculate the probability of the light being green ONLY on day 4 then it would be the exact same probability as every other day, which would be 17%. Now if we are trying to calculate the probability of the light being green on the first consecutive 4 days then we would need to multiply this probability (in decimal form) four times for the four days like so...
0.17 * 0.17 * 0.17 * 0.17 = x
0.00083521 = x ... times by 100 to get percentage
0.00083521 * 100 = 0.0835%
So the probability of the light being green 4 days in a row during your commute is 0.0835%

Step-by-step explanation:
You are given that P(A) = 0.5 and P(A ∪ B) = 0.7. Student 1 assumes that A and B are independent and calculates P(B) based on that assumption. Student 2 assumes that A and B are mutually exclusive and calculates P(B) based on that assumption. Find the absolute difference between the tw
Answer:
The absolute difference between the two calculations is 0.2
Step-by-step explanation:
Student 1
When the events do not affect each other, they are known as independent events. That is, two events are independent if the result of the second event is not affected by the result of the first event.
When two events are independent, the probability that A and B occur is equal to the product of the probability that A occurs and the probability that B occurs. Then:
P(A∩B)= P(A)*P(B)
The probability of the opposite event is equal to 1 minus the probability of the event. So in this case you have:
P(A'∩B')= 1 - P(A∪B)
Being P(A∪B)= 0.7, then:
P(A'∩B')= 1 -0.7
P(A'∩B')= 0.3
Being P(A)= 0.5 and P(A'), so
0.3= 0.5*P(B)
[tex]P(B')=\frac{0.3}{0.5}[/tex]
P(B')=0.6
Being P(B)= 1 - P(B') so P(B)= 1 - 0.6 and you get P(B)=0.4
Student 2
Two events are mutually exclusive when both cannot occur simultaneously. In other words, two events A and B are incompatible or mutually exclusive when they have no element in common. This is: P(A∩B)= 0
Being P(A∪B) =P(A) + P(B) - P(A∩B), P(A)=0.5 and P(A∪B)= 0.7, you get:
0.7=0.5 + P(B) -0
Solving:
0.7=0.5 + P(B)
0.7 - 0.5 = P(B)
0.2 = P(B)
Finally the absolute difference between the two calculations can be calcutated as:
|0.4 - 0.2|= 0.2
The absolute difference between the two calculations is 0.2

The manager of a park enclosed an area for small dogs to play. He made the length 15 feet longer than the width and enclosed an area covering 1350 square feet. What are the dimensions of the dogs' play area?
Answer:
Step-by-step explanation!
width = w
length = w + 15
So: w(w + 15) =1250 square feet
w^2 + 15w = 1250
Next you do: w^2+15w-1250=0
Then you use the quadratic formula to factor.

A box contains blue chips and red chips. A person selects two chips without replacement. If the probability of selecting a blue chip and a red chip is , and the probability of selecting a blue chip on the first draw is , find the probability of selecting the red chip on the second draw, given that the first chip selected was a blue chip.
Answer:
Prob ( 2nd Red 'given' 1st Blue ) = 0.8 = 4/5
Step-by-step explanation:
Prob ( A I B ) = Prob (A ⋂ B) / P (B)
Prob ( 2nd Red 'given' 1st Blue ) = P ( 2nd Red & 1st Blue ) / P ( 1st blue)
P ( 1st blue & 2nd red ) = 32/128 , P ( 1st blue ) = 5/16
So, P ( 2nd Red I 1st Blue ) = ( 32 / 128 ) / ( 5/16 )
= 0.8 = 4/5
Answer:
4/5

A cattle rancher wants to enclose a rectangular area and then divide it into three pens with fencing parallel to one side of the rectangle (see the figure below). There are 510 feet of fencing available to complete the job. What is the largest possible total area of the three pens?
Answer:
Step-by-step explanation:
4w + 2L = 670
2w + L = 335
L = 335 - 2w
Area A(w) = w(335 - 2w)
max occurs at the average of the solutions.
solutions are w=0 and w = 167.5
the average is 83.75
83.75 * (335 - 2 * 83.75) = 14028.125
A 40 : 1 scale model of an airplane is being used to conduct wind-tunnel tests. If the model is 4.5 feet long, how long is the actual airplane
Answer:
180 ft
Step-by-step explanation:
We are told that the scale model is 40:1. And that it's being used to conduct wind - tunnel tests.
This means 40 units represents 1ft.
This means that 4.5ft will be;
(4.5 × 40)/1 = 180 ft
Thus, the actual length of airplane would be 180 ft.

Solve the following equation for t: 5 ln (4t) = 16
Answer:
6.144
Step-by-step explanation:
Given the expression
5ln(4t) = 16
Required
Solve for t
5ln(4t) = 16
Divide both sides by 5
5ln(4t)/5 = 16/5
ln(4t) = 3.2
Apply exponent to both sides of the equation
e^ln(4t) = e^3.2
4t = e^3.2
4t = 24.53
t = 24.53/4
t = 6.144
The value of t is 6.144

Lisa was throwing a dart at a target. She threw 50 times with her left hand and 50 times with her right hand. The histograms show the distance Lisa missed the target by each time. Make an inference about which hand Lisa has better aim with based on the median of each data set. Justify your response in COMPLETE SENTENCES!!
Answer:
The left hand is more accurate.
Step-by-step explanation:
If you look at the graph, it will look like the right hand is more accurate, due to the fact that it has a closer distance than the left. However, the right hand actually never have hit the target while the left did more than once.

An undergraduate class has 24 biology majors and 17 chemistry majors. Eight students must be chosen at random to represent an event organizing committee. What is the probability of choosing exactly two chemistry majors
Answer: 0.19158
Step-by-step explanation:
Given: An undergraduate class has 24 biology majors and 17 chemistry majors.
Total students needs to be selected = 8
Number of ways to select 8 students out of 41= [tex]^{41}C_8[/tex]
Number of ways to select exactly two chemistry majors (i.e. rest 6 will be biology majors) = [tex]^{24}C_6\times ^{17}C_2[/tex]
Required probability = [tex]\dfrac{^{24}C_6\times ^{17}C_2}{^{41}C_8}[/tex]
[tex]=\dfrac{\dfrac{24!}{6!(24-6)!}\times\dfrac{17!}{2!(17-2)!}}{\dfrac{41!}{8!(41-8)!}}\\\\=\dfrac{134596\times136}{95548245}\\\\= 0.19158[/tex]
The probability of choosing exactly two chemistry majors = 0.19158
