The monthly worldwide average number of air- plane crashes of commercial airlines is 3.5. What is the probability that there will be
(a) at least 2 such accidents in the next month?
= λ^x × e^-λ/x!
λ = 3.5
x = at least 2 such accidents
x ≥ 2
= 1 - [P(x = 0) + P(x = 1)]
= 1 - [(3.5^0 × e^-3.5/0!)+ (3.5^1 × e^-3.5/1!)]
= 1 - [ 1 × 0.0301973834 + 3.5 × 0.0301973834]
1 - [ 0.0301973834+ 0.105690842]

λ = 3.5
x = at most 1 such accidents
x ≤ 1
= [P(x = 0) + P(x = 1)]
= [(3.5^0 × e^-3.5/0!)+ (3.5^1 × e^-3.5/1!)]
= [ (1 × 0.0301973834) + (3.5 × 0.0301973834)]

What is the total number of congruent sections/parts? (what
is the k value?)
how many congruent sections are there
Answer:
Total number of congruent sections/parts = 7
[tex] k = \frac{3}{7} [/tex]
Step-by-step explanation:
Given that partitions directed segment AB such that AP : PB = 3 : 4, this implies that:
There are 7 parts/congruent sections that AB has been divided into.
Also, point P, partitions AB in the ratio 3:4.
Therefore, there are a total of 7 congruent sections/parts.
Value of k:
Value of k = numerator of the original ratio ÷ sum of numerator and denominator of the original ratio
[tex] k = \frac{3}{3 + 4} [/tex]
[tex] k = \frac{3}{7} [/tex]
You have a coupon for 30% off your dinner. Your total bill was $50. You also need to pay a 7% sales tax and leave a 22% tip. With the discount, tip + tax included, how much was your dinner?
Answer:
$49.50
Step-by-step explanation:
30% of $50 = $15.00
7% of $50 = $3.50
22% of $50 = $11.00
$50.00 - $15.00 = $35.00
$35.00 + $3.50 = $38.50
$38.50 + $11.00 = $49.50
How much was your dinner?
The total amount is $49.50, so only a total of 50 cents is being taken off from the whole payment of the dinner. (≧◡≦) (o´∀`o) (´• ω •`) (＾▽＾) (⌒ω⌒)

How many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% w/w of salicylic acid?
Answer:
4.79 g
Step-by-step explanation:
mass of salicylic acid = ??
Mass of polyethylene = 75 g
% w/w concentration = 6% w/w
Let the mass of salicylic acid be x
Let the mass of solution = 75 + x
from
% w/w = mass of solute/ mass of solution * 100
Hence concentration of salicylic is;
6 = (x/75 + x) * 100
6/100 = x/75 + x
0.06 (75 + x) = x
4.5 + 0.06x =x
4.5 = x-0.06x
x = 4.5/0.94
x= 4.79 g
4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
To determine how many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid, the following calculation must be performed:
100 - 6 = 94 94 = 75 6 = X 6 x 75/94 = X 450/94 = X 4.7872 = X
Therefore, 4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.

You will use the GeoGebra geometry tool to divide a line segment in a given ratio. Go to line segment ratios, and complete each step below. If you need help, follow these instructions for using GeoGebra.
Question 1
Any line segment that is not horizontal or vertical can be represented as the hypotenuse of a right triangle whose legs are aligned with the x- and y-axes. In GeoGebra, is shown as the hypotenuse of such a triangle. You will divide in the ratio 2 : 3 using the ideas you’ve seen so far in the lesson:
Find and record the lengths of the horizontal and vertical sides of the right triangle.
Find and record the x-coordinate of a point that divides the horizontal side in the ratio 2 : 3. Use the formula from the lesson to guide you:
.
Find and record the y-coordinate of a point that divides the vertical side in the ratio 2 : 3. Use the formula from the lesson to guide you:
Consider a point C that has the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3 and the y-coordinate of the point that divides the vertical side in the ratio 2 : 3. Write down the coordinates of point C. This is the point that divides in the ratio of 2 : 3.
Answer:
(2.6,1.8)
Step-by-step explanation:
length of horizontal side = (xB − xA) = 4 units
length of vertical side = (yB − yA) = 2 units
To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to: a/a+b= 2/2+3= 2/5
Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A: Xc= Xa + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6
Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A: Yc= Ya + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8
It follows that point C is located at (2.6, 1.8).
Answer:
The coordinates of point C is (2.6,1.8)

Toni is shopping for clothes at the store she buys 8 shirts for $8.00 what is the unit rate for the shirts?
Answer:
$1.00
Step-by-step explanation:
The unit rate in this scenario would be $1.00 , meaning that Toni is paying $1.00 for every shirt. This can be calculated by dividing the total price that she is paying for the shirts by the total number of shirts that Toni is purchasing like so...
$8.00 / 8 = $1.00 per shirt
The unit rate is basically the value over the denominator of 1 which would be the case as seen above since $1 buys 1 shirt ([tex]\frac{1 dollar}{1 shirt}[/tex]) as opposed to $8 dollars 8 shirts ([tex]\frac{8 dollars}{8 shirts}[/tex]) as mentioned in the question.

The lions and the tigers played a football game the lions scored three more than three times the number of points the tigers scored
This question is incomplete
Complete Question
The lions and the tigers played a football game. The Lions scored three more than three times the number of points the Tigers scored. The total number of points scored by both teams is 31. How many points were scored by each team?
Answer:
The number of points scored by the Lions = 24
The number of points scored by the Tigers = 7
Step-by-step explanation:
Let the number of points scored by the lion = l
The number of points scored by the tiger = t
The Lions scored three more than three times the number of points the Tigers scored.
l = 3 + 3(t)
The total number of points scored by both teams is 31.
= l + t = 31
3 + 3t + t = 31
4t = 31 - 3
4t = 28
t = 28/4
t = 7 points
Note:
l + t = 31
I = 31 - t
l = 31 - 7
l = 24 points
The number of points scored by the Lions = 24
The number of points scored by the Tigers = 7

Sarah graphed the line that represents the equation y=−5x.
Which ordered pairs represent points on the line?
Select all that apply.
(6,−30)
(−2,−10)
(5,25)
(−3,15)
(1,−5)
Answer:
the ordered pairs which represent points on the line are
(6, -30) ⇒ A
(-3, 15) ⇒ D
(1, -5) ⇒ E
Step-by-step explanation:
To find the ordered pairs represents points on the line y = -5x, substitute x in the equation by the x-coordinate of each point if the value of y equals the y-coordinate of the point, then the point lies on the line
∵ y = -5x
∵ The ordered pair is (6, -30)
∴ x = 6 and y = -30
→ Substitute x in the equation by 6 to find y
∵ y = -5(6)
∴ y = -30
→ y has the same value of the y-coordinate of the point
∴ (6, -30) represents point on the line
∵ The ordered pair is (-2, -10)
∴ x = -2 and y = -10
→ Substitute x in the equation by -2 to find y
∵ y = -5(-2)
∴ y = 10
→ y does not have the same value of the y-coordinate of the point
∴ (-2, -10) does not represent a point on the line
∵ The ordered pair is (5, 25)
∴ x = 5 and y = 25
→ Substitute x in the equation by 5 to find y
∵ y = -5(5)
∴ y = -25
→ y does not have the same value of the y-coordinate of the point
∴ (5, 25) does not represent a point on the line
∵ The ordered pair is (-3, 15)
∴ x = -3 and y = 15
→ Substitute x in the equation by -3 to find y
∵ y = -5(-3)
∴ y = 15
→ y has the same value of the y-coordinate of the point
∴ (-3, 15) represents a point on the line
∵ The ordered pair is (1, -5)
∴ x = 1 and y = -5
→ Substitute x in the equation by 1 to find y
∵ y = -5(1)
∴ y = -5
→ y has the same value of the y-coordinate of the point
∴ (1, -5) represents a point on the line
