Step-by-step explanation:
Records show that Oliver is typically 10–30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve. John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late. What percentage of the time does Oliver arrive within 10 minutes of John's arrival time? O 26.7% O 33.3% 2 O 40% O 50%
Answer:
40%
Step-by-step explanation:
10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.
40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.
Given that,
Oliver is typically 10–30 minutes late for his shift at work.
The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.
John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.
We have to determine,
What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?
According to the question,
Oliver is typically 10–30 minutes late for his shift at work.
John and Oliver are working a shift that starts at the same time.
John always arrives 8 minutes late.
From the complete information, the probability distribution will be:
[tex]= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}[/tex]
Here, John always arrives 8 minutes late.
Therefore,
The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,
[tex]\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent[/tex]
Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

which segment is longer, please explain
Answer:
Blue, if you look, they both are close, but due to the pathagrium theory blue is longer.
Step-by-step explanation:
Answer:
Red is longer
Step-by-step explanation:
With the distance equation formula, you can find this. The distance equation formula is d=[tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} } \\[/tex]. (x1,y1)(x2,y2) are the coordinates of each individual point.
If you turn the grid into a graph, red's points would be (0,0)(3,3)
Blue's points would be (0,3)(-1,-1). Using the distance formula blue is [tex]\sqrt{17}[/tex].
The red is [tex]\sqrt{18}[/tex], so red is longer.

Step-by-step explanation:
An airplane takes off over flat area when it is 2500' above the Earth it has covered 3000' on the ground how many feet approximately has it flow through the air
Answer:
3905.12 feet
Step-by-step explanation:
we can form a triangle in order to use the Pythagorean theorem: a² + b² = h²
where:
a = distance covered on the ground
b = height above the Earth
3000² + 2500² = h²
h² = 9000000 + 6250000 = 15250000
h = √15250000
h = 3905.12 feet

Answer:
Multiplication
Step-by-step explanation:
This looks like the equation for the area of a rectangle.
Area = Lenght * Width
Given that the "l" variable and the "w" variable or next to each other without '/' or '\' , then we can safely say this a multiplication operation.
If there is no symbol between variables, it is assumed to be short-hand for multiplication instead of writing '*', '.', or 'x' in-between the variables.

if y varies directly with x, and y = -20 and x = 5, what is x when y = -30
Answer:
7.5
Step-by-step explanation:
The value of x = 7.5 when y = -30
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that y varies directly with x, and y = -20 and x = 5,
To determine the value of x = 7.5 when y = -30
Direct variation equations can be written as:
y = kx where "k" is a constant.
Substitute the values of y = -20 and x = 5 in the direct variation equation and solve for k:
⇒ -20 = 5k
⇒ k = -20/5
⇒ k = -4
The direct variation equation :
⇒ y = -4x
Substitute the values of y = -30 in the above equation and solve for x:
⇒ -30 = -4x
⇒ 4x = 30
⇒ x = 30/4
⇒ x = 7.5
Thus, the value ofx = 7.5 when y = -30

Write 0.12 as a fraction.
Let x = ?
100x = ?
100x - x = ? - ?
99x = ?
X = ?
Answer:
Let 0.12 be x.
Here, x is recurring in two decimal places so we'll multiply it by 10-
10x = 1.22Now, by subtracting them-
[tex] \\ \implies \sf \: 10x - x = 1.22 - 0.12 \\ \\ \\ \implies \sf \: 9x = 1.1 \\ [/tex]
Now, we'll divide both sides by 9 to get x as a fraction -
[tex] \\ \implies \sf \: x = \frac{1.1}{9} \\ \\ \\ \star \: \large{ \boxed{ \sf{x = \frac{11}{90} }}} \\ [/tex]
