Answer:
69090840 possible rankings
Step-by-step explanation:
The number of possible ranking ordered in terms of effectiveness can be obtained using permutation
Number of salesperson = 39
Number of rank = 5
nPr = n! ÷ (n - r)!
nPr = 39P5
39P5 = 39! ÷ (39 - 5)!
39P5 = 39! ÷ 34!
39P5 = 39 * 38 * 37 * 36 * 35 = 69090840

A teacher is flying a drone as shown in the diagram below. The drone is maintaining a height of approximately 150 feet above his eye level. What is the approximate angle of elevation from his eye level to the drone when the drone is approximately 200 feet away from him?
Answer:
Angle of elevation = 48.60° (Approx.)
Step-by-step explanation:
Given:
Vertical Height = 150 feet
Horizontal angular length of drone = 200 feet
Find:
Angle of elevation
Computation:
Using trigonometry function
⇒ Sinθ = Perpendicular / Hypotenuse
⇒ Sinθ = Vertical Height / Horizontal angular length of drone
⇒ Sinθ = 150 / 200
⇒ Sinθ = 0.75
⇒ Sin⁻¹(0.75) = θ
Angle of elevation = 48.60° (Approx.)

Find the distance between (-22,15) and (30, -25).
Answer:
65.60
Step-by-step explanation:
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2
= √522+(−40)2522+(-40)2
= √2704+16002704+1600
= √43044304 = 65.6049

Look at these numbers 11, 11 , 7 , 18 , 8 what is the correct way to put them in order so you can find the median
Answer:
7, 8, 11, 11, 18
Step-by-step explanation:
The order you put them in is from least to greatest:
7, 8, 11, 11, 18
There, you can find the median to be 11
Answer:
It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are. That is the mean.
Step-by-step explanation:
How many different 2-digit ID numbers can be made if each ID number can use the numbers 1 through 8 and no digits may be repeated?
Answer:1,2,5,7,8 and 9. Thus, we have 6 numbers.
Step-by-step explanation:Then we want to form two-digit numbers without repetition. There are 6 number that is possible to occupy first digit, right? 1,2,5,7,8 or 9. Because it’s without repetition, so the number that have been filled the first digit cannot be the second digit. Thus, the numbers that possible to occupy second place are 5 digits.So step by step

On a child’s birth, a deposit of $2000 was put into an account that pays 5% interest compounded annually. How much is in the account after 18 years?
Answer: $4,813.24
Step-by-step explanation:
This requires the use of a future value formula because we are to find the value of an amount in future after compounding it over a certain period.
Future Value = Amount * (1 + rate) ^ number of years
= 2,000 * ( 1 + 5%)¹⁸
= $4,813.24
In 18 years, the $2,000 would have increased to $4,813.24.
Solve for x
1/6 (2x - 12x) = 30
A) -12 B) -15 C) -18 D) -24
D (-18)

Several students were asked how many blocks they walk from home to school each day results are shown in the line plot below Miguel walks the shortest distance jila Watch the longest distance how much farther Then Miguel does jila walk?
Answer:
Miguel walks 4.25 blocks more than Jila.
Step-by-step explanation:
Line plot shown in the question represents the distance traveled by the students from their houses to their school.
From the line plot,
Distance between 1 and 2 = [tex]\frac{1}{4}[/tex] = 0.25 blocks
Shortest distance traveled by Miguel = 0.25 blocks
Longest distance traveled by Jila = 4.5 blocks
Difference between the distances covered by Miguel and Jila = 4.5 - 0.25
= 4.25 blocks
Therefore, Miguel walks 4.25 blocks more than Jila.
Little Snail is going to visit his friend over at the next pond, 3 miles away. He can crawl ( 1/2. 1/3, 1/4, 3/4, 2/3 ) of a mile per day. How many days will it take him to get there
Solution :
It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.
When the snail crawls 1/2 of a mile per day, it will take him, [tex]$1 \times \frac{2}{1} \times 3$[/tex]
= 6 days to get to the next pond.
When the snail crawls 1/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{1} \times 3$[/tex]
= 9 days to get to the next pond.
When the snail crawls 1/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{1} \times 3$[/tex]
= 12 days to get to the next pond.
When the snail crawls 3/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{3} \times 3$[/tex]
= 4 days to get to the next pond.
When the snail crawls 2/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{2} \times 3$[/tex]
= 4.5 days to get to the next pond.

Answer:
[tex]x \geq 15[/tex]
Step-by-step explanation:
Solving an inequality is very similar to solving an equation, one uses inverse operations. The only major difference between the two is that when one multiplies or divides an inequality by a negative number, one must remember to flip the inequality sign to ensure that the inequality remains true. In this situation, such a rule does not come into play.
[tex]\frac{x}{5} - 8 \geq -5[/tex]
Inverse operations,
[tex]\frac{x}{5}-8 \geq -5\\ +8\\\\\frac{x}{5} \geq 3\\*5\\\\x \geq 15[/tex]

Which is the equation of the given line in point-slope form?
y-0=1(x+8)
y-0=-1(3-8)
y=-2 +8
y-8=-1(2+0)
Answer:
y-8=-1×(x+0)
Step-by-step explanation:
m=y2-y1/x2-x1
m=0-(8)/8-(0)
m=-8/8-(0)
m=-8/8+0
m=-8/8
m=-1
y-(8)=-1×(x-(0))
y-8=-1×(x+0)

Kate multiplied two binomials using the distributive property. She made a
mistake in one of the steps. Where did she first make a mistake?
(x - 2)(3x + 4)
1. (x-2)(3x) + (x + 2)(4)
2. (X)(3x) + (-2)(3x) + (x)(4) + (2)(4)
3. 3x2 - 6x + 4x + 8
4.3x2 - 2x + 8
Answer:
step 1
Step-by-step explanation:
Given
(x - 2)(3x + 4) ← apply distributive property
= (x - 2)(3x) + (x - 2)(4)
↑ error is here , she put (x + 2)
In this exercise we have to use the knowledge of the distributive property, so In alternative 1 she made the mistake.
What is distributive property example?The distributive property is used when a number is multiplying an addition or subtraction. Simply multiply each term separately and add or subtract the result. We distribute the multiplication of the 2, to the 8 and to the 3.
Proving the mistake:
[tex](x - 2)(3x + 4) \\= (X)(3x) + (-2)(3x) + (x)(4) + (2)(4)\\and not\\(x-2)(3x) + (x + 2)(4)[/tex]
