Answer:
hello your question is incomplete below is the complete question
A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: 12 16 18 19,21 21, 21,22 24 24 26What is the arithmetic mean, median and mode? what is the most likely shape of the distribution
answer :
i) mean = 20.36
ii) median = 21
iii) mode = 21
iv) The most likely shape is a Bell - shaped curve
Step-by-step explanation:
sample size = 11
values ( observations ) = 12, 16, 18, 19,21,21,21,22,24,24,26
i) mean
= ∑ values / sample size = 224 / 11 = 20.36
ii) median
median is the value of the data located at the center of the string of data
to determine the middle position = ( n+1 / 2 )
where n = sample size
hence position of median value = 11 + 1 / 2 = 12 / 2 = 6
the value at the 6th position = 21 ( median )
iii) mode
mode = most repeated value in the series of data
hence mode value = 21

What would be the first five terms of sequence whose first term is 1 and has a common ratio of 1/3?
Answer:
Step-by-step explanation:
This is a geometric sequence; we know that because of the words "common ratio." The general formula for a geometric sequence is
a(n) = a(1)*r^(n - 1), where r is the common ratio.
Here, a(1) = 1, r = 1/3, and so
a(1) = 1 (given)
a(2) = 1/3 (this is a(1) multiplied by 1/3)
a(3) = 1/9 (this is a(2) multiplied by 1/3)
a(4) = 1/27
a(5) = 1/81

I need help with this problem please.
Step-by-step explanation:
Airplane One 425m/h x 2h= 850 miles traveled N5°W
Airplane Two 530m/h x 2h= 1060 miles traveled N67°E
5 degrees + 67 degrees = 72 degrees divergence of the Airplane One and Two
Draw a triangle, the smallest side is 850 and adjacent to 1060 side. The angle between these two sides is 72 degrees
Use the acronym SOH CAH TOA to find the side which is the distance between the 2 airplanes after 2 hours
sine 72= opposite/hypotheneus
sine 72= opposite/1060
opposite = (sine 72)(1060)= 1008 miles distance between Airplane One and Airplane Two
X increased by 10 is equal to 42
Answer:
x = 32
Step-by-step explanation:
x + 10 = 42, then you subtract 10 from both sides to get 32

Hank has 4 green marbles for every 9 red marbles. If hank has 39 total marbles, how many green marbles does he have? pls answer ASAP it for assignment
Answer:
12 green marbles
Step-by-step explanation:
in this case we have to add the the green marbles as 4 and red marbles as 9
so, 4 + 9 = 13 and divide the total marbles to it
so, 39/13 = 3
so, here we have 3 times marble in 13 green marble to get the total number
so, 3 (13)
so, in this case we have to separate the green and red
so, 13 as ( 9 red + 4 green)
so,3 times ( 9 red + 4 green)
in this case we can use distributive property of multiplication
so, 3 times 9 red = 27 is the total red marbles
and 3 times 4 green = 12 is the total green marbles
to check the answer we have to add this two
so, 27 red marbles + 12 green marbles = 39 total marbles
so, that's why it is 12 green marbles

Answer:
AC = 30, BD = 30, BE = 15, AB = 27, BC = 13.1
Step-by-step explanation:
AC = AE * 2
BD = BE * 2
BE = AE
AB = CD
BC = [tex]\sqrt{30^{2}-27^{2} }[/tex] (Pythagorean theorem)
What is the answer to 0=V+19
Answer:
v= -19
Step-by-step explanation:
Solve for V by simplifying both sides of the equation, then isolating the variable.
Answer:
-19
Step-by-step explanation:
+19 -19 = 0
Therefore,
V = -19
Subtract 19 from both sides 0 - 19 = -19,
-19 = V
One fruit punch has 10% juice and another has 50%. How much of the 10% should be mixed with 30 gal of the 50% to create punch that is 25% juice
Answer:
We combine x ounces of 100% juice
with 40-x of 10% juice
to get 40 ounces of 55% juice
x + 0.1(40-x) = .55(40)
x + 4 - 0.1x = 22
0.9x + 4 = 22
.09x = 18
x = 20 ounces of 100% juice
40-x = 20 ounces of 10% juice
We combine 20 ounces of each.

Each triangle in the net below has a base of 6 centimeters and a height of 8 centimeters. What is the surface area, in square centimeters, of the figure represented by the net? helpppppp i need help pls
The area of a triangle is 1/2 x base x height.
The area of the triangle is 1/2 x 6 x 8 = 24 square cm.
There are 4 identical triangles so 24 x 4 = 96 square cm.
The area of the square base = 6 x 6 = 36 square cm.
Total area = 96 + 36 = 132 square cm.
