A superball rebounds half the height it drops. A student drops the superball from the top of a building, 176 feet above the ground. How far
above the ground is the ball when it has traveled a distance of 500 feet?

Answers

Answer:

62.48 ft.

Step-by-step explanation:

Initial height: 50 ft.

First rebound: 10 ft.

Second rebound: 2 ft.

Third rebound: 0.4 ft.

Fourth rebound: 0.08 ft.

If we approximate the fourth rebound to zero, we'll have:

50 + 10 + 2 + 0.4 + 0.08 = 62.48 ft.

According to recent UN figures, the annual gun homicide rate is 62.4 per one million residents in the US and 1.3 per one million residents in Britain. Compare the proportion of residents killed annually by guns using the (a) difference of proportions, (b) relative risk. Which measure is more useful for describing the strength of association

Answers

Answer:

[tex]P_D=61.1*10^{-4}[/tex]

[tex]R_r=480[/tex]

Step-by-step explanation:

From the question we are told that

Homicide rate in US [tex]R_U=62.4\ per\ one\ million[/tex]

Homicide rate in Britain [tex]R_B=1.3\ per\ one\ million[/tex]

Generally the equation for probability of homicide is mathematically given as

[tex]P=\frac{R}{10^6}[/tex]

Generally the equation for probability of homicide in US is mathematically given as

[tex]P_U=\frac{62.4}{10^6}[/tex]

[tex]P_U=62.4*10^{-4}[/tex]

Generally the equation for probability of homicide in Britain is mathematically given as

[tex]P_B=\frac{1.3}{10^6}[/tex]

[tex]P_B=1.3*10^{-5}[/tex]

a)Generally the difference b/w the probabilities P_D is mathematically given as

[tex]P_D=P_U-P_B[/tex]

[tex]P_D=62.4*10^{-4}-1.3*10^{-5}[/tex]

[tex]P_D=61.1*10^{-4}[/tex]

Therefore US annual homicide is [tex]P_D=61.1*10^{-4}[/tex] greater than Britain's

b)Generally the Relative risk is R_r is mathematically given as

[tex]R_r=\frac{P_U}{P_B}[/tex]

[tex]R_r=\frac{62.4*10^{-4}}{1.3*10^{-5}}[/tex]

[tex]R_r=480[/tex]

75% of what number is 120?

Question 1 options:

1.6


160


10,800

Answers

Answer:

160

Step-by-step explanation:

First, lets assign a varible x. Let x be the number where 75% of x is 120. Next, we can convert the words of the problem into an equation. Now we have, 75% * x = 120 = 0.75x = 120. By multiplying both sides by 100, we get, 75x = 12000. So, x = 160.

A water pipe is 4 7/12 feet beneath the surface of the road. What is the elevation of the pipe, in feet, expressed as a decimal?

Answers

Answer:

4.5833feet

Step-by-step explanation:

Given the elevation of a water pipe as 4 7/12 feet

Expressing as decimal

4 7/12  

= 4 + 7/12

=  4 + 0.5833

= 4.5833

Hence the elevation of the pipe expressed as a decimal is 4.5833feet

Step-by-step explanation: Since we know the triangles are proportional, we need to set up an proportion to find TS. First, let find which sides are correspond with each, TS and MN does and US and NQ does. So we set up a proportion that includes.

TS/US=MN/NQ: Let plug in the numbers

3x+1/26=5x-2/39:  Then cross multiply

39(3x+1)=26(5x-2): Then simplify

117x+39=130x-52: Subtract 117x from both sides

39=13x-52: Add 52 to both sides

  91=13x: Divide 13 by both sides

  7=x: Then plug it in to TS

3(7)+1=22

Find the x-and y-intercepts.
4x + y = 12x - 1
The x-intercept is
The y-intercept is

Answers

Answer:

The x-intercept is [tex]\frac{1}{8}[/tex]

The y-intercept is -1

Step-by-step explanation:

Lets find x-intercept:

for y substitute 0

4x+0=12x-1

subtract 4x both sides

0=8x-1

add 1 both sides

1=8x

divide 8 both sides

[tex]\frac{1}{8}[/tex]=x

lets find y-intercept:

for x substitute 0

4(0)+y=12(0)-1

multiply 4(0) and 12(0) which would equal 0 in this case, you dont have to write the 0s.

y=-1

At a carnival, the probability that you chose a winning rubber duck from 25 ducks is 0.20.

How many are not winning ducks?

Answers

The game is formed such that a duck is either winning duck or a non winning duck .

there is no other result for any duck present in the game .

Also choosing a duck is a fair game it is independent of any prior situation .

here we would be using a basic probability formula , that is

Probability of a result = number of items in favour of that result divide by total number of items present in the game .

Which is the equation of a line parallel to the line with the equation:
y = 1/4x + 2

Answers

answer:

y=1/4x-7

Step-by-step explanation:

equations with the same slope are parallel no matter the y-intercept

Answer:

I don't think it's specified but I can tell you the slop has to stay the same but the y-intercept ha

s to be a different number.

if over a certain point the all you have to do is plug the points into x and y and remove the y intercept. An example is what line is parallel to y=1/4x+2 and crosses point (4,2).

Then you first have to plug in x and y and remove the y intercept to find a new y intercept. 2=1/4(4)+B

Next is to put together common like terms. 2=1+B

Then subtract one because that's it's opposite leaving B=1

then you substitute or replace the old y intercept with the new one making the answer Y=1/4x+1

I hope this will help you.

what is 3/4÷ 1/8? with a explanation ​

Answers

Answer:

The answer is 6.

Step-by-step explanation:

you have 3/4 divided by 1/8, first you find a common denominator, which is 8. Second you do 3 x 2 and 4 x 2, you should get 6/8 divided by 1/8, and 6 divided by 1 is still 6.

Answer:

6

Step-by-step explanation:

3 /4   × 8 /1 =

3×8/4×1=24/4

3x8 is the numerator 4x1 is the denominator

24/4=6

3/4÷1/8=6

An ecological group suspects lobsters are consuming dangerous levels of mercury in a region of the world. Dangerous levels of mercury are classified when they reach beyond 6.5 parts per million. A random sample of 25 lobsters in the region were tested and the data is shown in the stemplot.

5|6 8 9;
6|3 4;
6|6 7 8;
7|1 2;

Key: 2|2 = 2.2 parts per million

Part A: What proportion of the lobsters in the sample have dangerous levels of mercury in their systems? (4 points)

Part B: Construct and interpret a 95% confidence interval for the mean mercury levels of the lobsters if the sample of 25 lobsters has a mean mercury level of 5.05 parts per million and standard deviation of 1.45 parts per million. (6 points)

Answers

Part A: 5 out 25 lobsters have dangerous levels of mercury

Part B: the 95% confidence interval is given by (4.45, 5.65)

since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064

Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)

For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65

At what corridnate point do y= 1/2 x + 4 and x + 4y = 4 intersect.

Answers

Answer:

(-4;2)

Step-by-step explanation:

1. if y=1/2 x+4, then 2y=x+8; it is possible to re-write as x-2y+8=0;

2. if x+4y=4, it is possible to re-write it as x+4y-4=0;

3. if x-2y+8=0 and x+4y-4=0, then x-2y+8=x+4y-4; ⇒ -2y+8=4y-4; ⇒ 6y=12; ⇔ y=2.

4. if y=2, then it is possible to substitute its value into any equation given in the condition:

x+4y=4 (substitution y=2); ⇒ x+8=4; ⇒ x= -4.

5. finally x= -4; y=2. It means (-4;2)
