Answer:
The mean of A and C is equal to 10.
Step-by-step explanation:
We know that,
[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Total no of obervations}}[/tex]
The mean of A and B is 20,
[tex]A+B=20\\\\A+B=40\ \ .........(1)[/tex]
The mean of B and C is 24,
[tex]B+C=24\times 2\\\\B+C=48\ \ .........(2)[/tex]
The mean of A,B and C is 18,
[tex]A+B+C=18\times 3\\\\A+B+C=54\ .....(3)[/tex]
Put the value of A+B from (1) in (3),
C = 14
Put the value of B+C from (2) in (3)
A = 6
Mean of A and C is :
[tex]M=\dfrac{A+C}{2}\\\\M=\dfrac{14+6}{2}\\\\M=10[/tex]
So, the mean of A and C is equal to 10.

Each fier station hose at the la salle fier station is 25 yards long. The station needs enough fier hoses to reach from any fier hoses to reach from any fier hydrant to the farthest house wich could be up to 230 feet away. What is the minimum number of hoses that the la salle fier station should have.
Answer:
4
Step-by-step explanation:
minimum number of hoses needed = farthest length / length of a hose
convert the length of a hose to feet
1 yards = 3 feet
25 x 3 = 75 feet
230 / 75 = 3.1
4 hoses would be needed

Answer:
145
Step-by-step explanation:
Supplementary angles add up to equal 180 degrees
Thus, ∠ABC + ∠DEF = 180°
If ∠ABC = 35
Then 35 + ∠DEF = 180
180 - 35 = 145
Hence, ∠DEF = 145

When the median is ten what does it represent
Answer:
whole question?
Step-by-step explanation:
Answer:
Ten is the middle value in a set of numbers.
Step-by-step explanation:
Remember mean, median, and mode.
Mean: has an "a" so you can remember it's the average of the set of numbers
Mode: starts with "mo" and is the most frequent in a set of numbers
Median: has an "i" for being in the middle of the set

The Table below is a data set that lists how many pairs of shoes are owned by some of your classmates.
Using the data set, what is the median?
Answer:
7.5
Step-by-step explanation:
To find the median, first order the numbers from least to greatest:
2, 4, 5, 7, 8, 8, 10, 12
Then, find the middle number (number in the middle):
There are 2 middle numbers. 7 and 8.
Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.
To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;
7 + 8 = 15
15 / 2 = 7.5

Each bar includes the left-end value but not the right-end value. For example, the first bar
includes dogs that weigh 60 pounds and 68 pounds but not 80 pounds.
Step-by-step explanation:
Answers:
How many dogs weigh at least 100 pounds?
14 + 5+ 3 + 1 = 23 dogs.
How many dogs weigh exactly 70 pounds?
is unknown, so will be 60-79 .
How many dogs weigh at least 120 and less than 160 pounds?
8 dogs weigh 120 less than 160 pounds.
How much does the heaviest dog at the show weigh?
is unknown, but could be between - 160-179
What would you consider a typical weight for a dog at this dog show? Explain your reasoning.
A typical dog weighs can be 100 - 120.

Step-by-step explanation:
Help please !!!!!!!!!!!
Answer:
See below for answers and explanations to the first 5 problems
Step-by-step explanation:
Problem 1:
cos(x) = 2/3
sec(x) = ?
sec(x) = 1/cos(x)
sec(x) = 1/(2/3)
sec(x) = 3/2
Problem 2:
sinβ = -5/6
cscβ = ?
cscβ = 1/sinβ
cscβ = 1/(-5/6)
cscβ = -6/5
Problem 3:
secφ = 2
tanφ = √3
sinφ = ?
secφ = 1/cosφ
tanφ = sinφ/cosφ
tanφ = sinφ/cosφ
tanφ = sinφ(1/secφ)
√3 = sinφ(1/2)
2√3 = sinφ
Problem 4:
secθ = 8
tanθ = 3√7
cscθ = ?
secθ = 1/cosθ
tanθ = sinθ/cosθ
cscθ = 1/sinθ
tanθ = sinθ/cosθ
tanθ = sinθ(1/cosθ)
3√7 = sinθsecθ
3√7 = sinθ(8)
(3√7)/8 = sinθ
cscθ = 1/sinθ
cscθ = 1/((3√7)/8)
cscθ = 8/(3√7)
cscθ = (8√7)/21
Problem 5:
sinθ = 2/√5
cosθ = 1/√5
tanθ = ?
tanθ = sinθ/cosθ
tanθ = (2/√5)/(1/√5)
tanθ = (2/√5)(√5)
tanθ = 2
At a point on the ground 50 feet from the foot of a tree, the angle of
elevation to the top of the tree is 53 degrees. Find the height of the tree.
Round to the nearest hundredths.
Answer:
66.35 feet
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent
= tan θ = Opposite/Adjacent
θ = 53°
Opposite = Height of the tree = h
Adjacent = Point of the ground from the foot of the tree = 50 ft
Hence,
tan 53 = h/50ft
Cross Multiply
h = tan 53 × 50ft
h = 66.352241081 ft
Approximately to the nearest hundredth, the height of the tree = 66.35 feet
Ms. Dos has already driven 94.6 miles towards los angeles and it took her 1.1 hours to get that far write a multiplication problem that gives Ms. Dodos average speed
Answer: 86 mph
Step-by-step explanation:
Given
Ms. Dos has driven 94.6 miles
Time is taken 1.1 hours
Average speed is given by the ratio of total distance and total time taken
[tex]\Rightarrow \text{Average speed v=}\dfrac{94.6}{1.1}\\\\\Rightarrow v=86\ mph[/tex]
If x/y =6, y/w =4, and x=36, what is the value of w? (A) 1 2 (B) 3 2 (C) 2 (D) 4 (E) 6
Answer:
w = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{y}[/tex] = 6 and x = 36 , then
[tex]\frac{36}{y}[/tex] = 6 ( multiply both sides by y )
36 = 6y ( divide both sides by 6 (
6 = y
Then
[tex]\frac{y}{w}[/tex] = 4 , that is
[tex]\frac{6}{w}[/tex] = 4 ( multiply both sides by w )
6 = 4w ( divide both sides by 4 )
[tex]\frac{6}{4}[/tex] = w , that is
w = [tex]\frac{3}{2}[/tex]

What is the area for the parallelogram
a. 4664.49 squared cm
b. 4272 squared cm
c. 4000 squared cm
d. 3690 squared cm
=========================================
Work Shown:
area = base*height
area = c*h
area = 89*48
area = 4272 square cm
Side notes:
The base and height are always perpendicular to one another.The value of a = 52.41 isn't used at all.Does anyone know how to solve this?
Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -5 to -4, it increases = [-5, -4]
For x = 1 to 3, it increases = [1, 3]
Answer: [-5, -4] , [1, 3]
