H varies directly to the cube of c. When H =40 c=2. find the value of when H=5000
Answer:
c = 10
Step-by-step explanation:
Given that H varies directly as c³ then the equation relating them is
H = kc³ ← k is the constant of variation
To find k use the condition when H = 40, c = 2 , then
40 = k × 2³ = 8k ( divide both sides by 8 )
5 = k
H = 5c³ ← equation of variation
When H = 5 000, then
5000 = 5c³ ( divide both sides by 5 )
1000 = c³ ( take the cube root of both sides )
[tex]\sqrt[3]{1000}[/tex] = c , so
c = 10
Find the interquartile range (IQR) and list any outliers: 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74 A. IQR = 39: 89 is an outlier B. IQR = 17: no outliers C. IQR = 39: no outliers D. IQR = 17: 50 is an outlie
Given:
The data set is 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74.
To find:
The IQR and outliers.
Solution:
The given data set is
60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74
Arrange the data values in ascending order.
50, 54, 60, 62, 67, 70, 70, 74, 74, 82, 88, 89
Divide the data set in two equal parts.
(50, 54, 60, 62, 67, 70), (70, 74, 74, 82, 88, 89)
Divide each parentheses in two equal parts.
(50, 54, 60), (62, 67, 70), (70, 74, 74), (82, 88, 89)
Now,
[tex]Q_1=\dfrac{60+62}{2}[/tex]
[tex]Q_1=\dfrac{122}{2}[/tex]
[tex]Q_1=61[/tex]
And,
[tex]Q_3=\dfrac{74+82}{2}[/tex]
[tex]Q_3=\dfrac{156}{2}[/tex]
[tex]Q_3=78[/tex]
We know that, the inter quartile range is
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=78-61[/tex]
[tex]IQR=17[/tex]
The IQR is 17.
If the data values lie outside the interval [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex], then those values are known as outliers.
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[61-1.5(17),78+1.5(17)][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[35.5,103.5][/tex]
All data values lie in the interval [35.5,103.5]. So, there are no outliers.
Therefore, the correct option is B.

Devin jumped off a cliff into the ocean in Acapulco while vacationing with his family. His height as a function of time could be modeled by the function h(t)= -16t square root 2 +16t +96, where T is the time in seconds and H is the time in feet. How many seconds until Devon hit the water? Around to the nearest tenth is necessary.
Answer:
3 seconds
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
hence it will take 3 seconds until Devon hit the water
Matt is the catcher for his schools baseball team. The catcher must be able to throw from home plate to the second base. What is the distance from home plate to second
Answer:
The distance from one base to the next is 90 ft. You can make a right triangle with two sides being 90 ft and the long side being the distance between home and second. Then you use the pythagorean theorem to find that distance.
90^2 + 90^2 = d^2
d = sqrt (16200) = 127.28 ft

A rowing team rowed 60 miles while going with the current in the same amount of time as it took to row 30 miles going against the current. The rate of the current was 3 miles per hour. Find the rate of the rowing team in still water.
Answer:
9
Step-by-step explanation:
60/(v+3)=30/(v-3)
2(v-3)=v+3
2v-6=v+3
v=9
Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
The rate of the rowing team in still water is 9 miles per hour.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Speed = Distance / Time
We have,
The speed of the current:
V = 3 miles per hour
Rowed with the current:
Speed = V + 3
Distance = 60 miles
Rowing against the current:
Speed = V - 3
Distance = 30 miles
Rowing with the current and against the current took the same time.
Speed = Distance / Time
Time = Distance / Speed
Now,
Time for rowing with the current = Time for rowing against the current
60 / (V + 3) = 30 / (V - 3)
2 / (V + 3) = 1 / (V - 3)
2 (V - 3) = V + 3
2V - 6 = V + 3
2V - V = 3 + 6
V = 9
Thus,
The rate of the rowing team in still water is 9 miles per hour.

Skylar has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 160 points for a free movie ticket. Write and solve an equation which can be used to determine x, the number of visits Skylar must make to earn a free movie ticket.
In order to win the free movie ticket, Skylar must visit the theater 10 times
The equation that can be used to represent the explanation given in the question is : 160 = 85 + 7.5x
The 85 reward points that Skylar gets for signing up can be likened to fixed point. This point does not change with the number of theater visits.The 7.5 points she earns for each visit to theater can be described as variable point. This point increases with the number of theater visits. The total number of points she can earn from a cinema visit = 7.5 × x = 75x.where x represents the number of cinema visits
Given this equation: 160 = 85 + 7.5x, take the following steps to determine the number of visits Skylar needs to earn the movie ticket:
Combine similar terms
160 - 85 = 7.5x
75 = 7.5x
Divide both sides of the equation by 7.5
75 / 7.5 = x
x = 10
