Between 12:00 PM and 1:00 PM, cars arrive at a local bank's drive-thru at the rate of cars per hour ( car per minute). The formula below from probability can be used to determine the probability that a car will arrive within t minutes of 12:00 PM. Use this information to answer the questions given below in parts (a)(e).
Complete question :
Between 12:00 PM and 1:00 PM, cars arrive at Citibank’s drive-thru at the rate of 6 cars per hour (0.1 car per minute). The following formula from statistics can be used to determine the probability that a car will arrive within t minutes of 12:00 PM. F(t)=1−e^−0.1t
Determine how many minutes are needed for the probability to reach 80%.
Answer:
16.09 minutes
Step-by-step explanation:
Given the function :
F(t)=1−e^−0.1t
To attain 80% probability ; 80% = 0.8
0.8 = 1 - e^-0.1t
0.8 - 1 = - e^-0.1t
-0.2 = - e^-0.1t
Take the In of both sides
In(0.2) = In( e^-0.1t)
−1.609437 = - 0.1t
Divide both sides by - 0.1
−1.609437 / -0.1 = - 0.1t / 0.1
16.09 = t
Hence, the time it'll take will be 16.09 minutes
Answer:
80/100=0.80
.8=1-e^-0.3t
.8+1=-e^-0.3t
1.8=-e^-.3t
t=5.36

Lauryn grew p tomato plants. Padma grew 5 fewer than 3 times the number Lauryn grew. Kent grew 6 more than 4 times the number Lauryn grew. Choose an expression and a simplified expression to represent the total number of tomato plants that Lauryn, Padma, and Kent grew. Select all that apply.
Answer:
A. p + (3p – 5) + (4p + 6)
D. 8p + 1
Step-by-step explanation:
A. p + (3p – 5) + (4p + 6)
B. p + (5 – 3p) + (6 + 4p)
C. p + 11
D. 8p + 1
E. 7p – 1
Lauryn = p tomatoes
Padma = (3p - 5) tomatoes
Kent = (4p + 6) tomatoes
Total number of tomato plants that Lauryn, Padma, and Kent grew = Lauryn + Padma + Kent
= p + (3p - 5) + (4p + 6)
= p + 3p - 5 + 4p + 6
= p + 3p + 4p - 5 + 6
= 8p + 1
Total number of tomato plants that Lauryn, Padma, and Kent grew = 8p + 1
A. p + (3p – 5) + (4p + 6)
D. 8p + 1

Answer:
3x4
Step-by-step explanation:
If you draw a rectangle with a length of 4 and a width of 3, it will have 12 sq units as the area.
This is because A=lw. If the area is 12, the length and width must multiply to get 12. 3x4=12.

The quadrilateral ABCD has area of 58 in2 and diagonal AC = 14.5 in. Find the length of diagonal BD if AC ⊥ BD.
Answer:
(look in the the Step by step)
Step-by-step explanation:
When the diagonals of a quadrilateral are perpendicular, the area of that quadrilateral is half the product of their lengths.
.. A = (1/2)*d₁*d₂
Substituting the given information, this becomes
.. 58 in² = (1/2)*(14.5 in)*d₂
.. 2*58/14.5 in = d₂ = 8 in
The length of diagonal BD is 8 in.
Answer:
BD = 8 in.

find the area of the shaded part
Answer:
Step-by-step explanation:
the easiest thing to do is to make the half squares which you have 4 into 2 whole squares then base times height
4x3=12
Answer:
26cm²
Step-by-step explanation:
Alrighty, let's go count squares:
On the top row, there's 4 (adding the halves together), on the second row there's 5, and on the bottom row there's also 4, so we add that all together to get:
4 + 5 + 4 = 13
But, because each square is 2 cm, we have to multiply:
13 x 2 = 26
So, the area of the shaded section is 26cm²

Step-by-step explanation:
[tex](x + 9) {}^{2} [/tex]
Apply foil method.
[tex](x + 9) {}^{2} = (x + 9)(x + 9)[/tex]
Multiply the first terms, X
[tex]x \times x = {x}^{2} [/tex]
Multiply outer terms, 9 and x.
[tex]x \times 9 = 9x[/tex]
Multiply inner terms,
[tex]9 \times x = 9x[/tex]
Multiply outer terms.
[tex]9 \times 9 = 81[/tex]
Add the inner and outer terms
[tex]9x + 9x = 18x[/tex]

The price of pants is bigger than the price of a shirt by 4$.
Mike bought 10 shirts and 5 pants.
Mike payed 20$ more for the shirts than the pants.
How much does a shirt cost?
How much do pants cost?
Answer: A shirt costs $8 and the pants cost $ 12.
Step-by-step explanation:
Let x = Cost of each shirt, y = Cost of each pant.
As per given, we have
[tex]y-x=4 \ \ \ (i)\\\\ 10x-5y = 20\ \ \ (ii)[/tex]
Multiply 5 on both sides of (i), we get
[tex]5y-5x=20 \ \ \ (iii)[/tex]
Add (ii) and (iii), we get
[tex]5x=40\\\\\Rightarrow\ x=8[/tex]
From (i), y=4+8=12
Hence, a shirt costs $8 and the pants cost $ 12.

What is the sum of (5x - 10) and (-X + 8) ?
Answer:
4x-2
Step-by-step explanation:
(5x-10)+(-x+8)
5x-10-x+8
5x-x-10+8
4x-10+8
4x-2
Therefore, the sum is 4x-2
Answer:
4x - 2
Step-by-step explanation:
(5x - 10) + (-x + 8)
To solve this problem, one must simplify, combine like terms. One can only combine a variable unit with another variable unit, likewise, one can only combine a constant (numerical term) with another constant.
(5x - 10) + (-x + 8)
= 5x - 10 - x + 8
= 4x - 2

A baseball is thrown up in the air. The table shows the heights y (in feet) of the baseball after x seconds. Write an equation for the path of the baseball. Find the height of the baseball after 1.7 seconds.
The equation of an object in free fall is the equation of a parabola
The equation for the path of the ball is y = -16·x² + 36·x + 4The baseball height, after 1.7 seconds is 18.89 feet.
The reason the above values are correct are as follows:
The known parameters are;
The direction of the baseball is up in the air
The values of the height of the baseball after x seconds is given as follows;
[tex]\begin{array}{ccc}\mathbf{Time, \ x}&&\mathbf{Baseball \ height, \ y}\\0.5&&18\\1&&24\\1.5&&22\\2&&12\end{array}\right][/tex]
Required;To write the equation for the path of the baseball
Solution:
The general equation of the motion of free fall is the equation of a parabola, which can be written as follows;
y = a·x² + b·x + c
From the given table, we have;
18 = a·0.5² + b·0.5 + c = 0.25·a + 0.5·b + c
18 = 0.25·a + 0.5·b + c...(1)
24 = a + b + c...(2)
22 = 2.25·a + 1.5·b + c...(3)
12 = 4·a + 2·b + c...(4)
Subtracting equation (1), from (2), to get equation (5) and subtracting equation (3) from (4) to get equation (6) gives;
6 = 0.75·a + 0.5·b...(5)
-10 = 1.75·a + 0.5·b...(6)
Subtracting equation (5) from equation (6) gives;
-10 - 6 = 1.75·a - 0.75·a = a
a = -16
From equation (5), we get;
6 = 0.75 × (-16) + 0.5·b
b = (6 - 0.75 × (-16))/0.5 = 36
b = 36
From equation (2), we get;
24 = (-16) + 36 + c
c = 24 - ((-16) + 36) = 4
The equation for the path of the ball is y = -16·x² + 36·x + 4
Required;The height of the baseball after 1.7 seconds
Solution:
The height, y, of baseball after 1.7 seconds is given by substituting for the time x = 1.7 in the equation of the baseball as follows;
After 1.7 seconds, y = -16 × 1.7² + 36 × 1.7 + 4 = 18.89
The height of the baseball y, after 1.7 seconds is 18.89 feet.
