Answer:
A) mean = 1.2
B) median
C) The measures of center use data points to approximate a middle value or average of a given data set
Step-by-step explanation:
The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution.
The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler).
A) The balance point for the points 0.4, 1.4, and 1.8. Will be
(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2
B) The median is the measure of center that is indicated by the center of balance
The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.
C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.

Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 1 < x < 5.
Answer:
180
Step-by-step explanation:
The average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.
Find the average rate of change?The average rate of change is the change in the slope of the function, it is given by the formula,
[tex]\text{Average rate of change} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Given to us
y₂ = f(x₂) = 27
x₂ = 3
y₁ = f(x₁) = 9
x₁ = 2
Substitute the values in the formula,
[tex]\text{Average rate of change} = \dfrac{27-9}{3-2} = 18[/tex]
Hence, the average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.

2x+y=8
Substitute y=2 into the second equation
2x+2=8
Subtract 2 from each side
2x+2-2=8-2

find the value of y
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Given 2 secants from an external point to the circle.
The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is
9 + 3y = 22 ( subtract 9 from both parts )
3y = 13 ( divide both sides by 3 )
y ≈ 4. 3 cm ( to the nearest tenth )

is 246. The sum of the 10th and the 14th element is 298. What is the value of
the 35th term?
Answer:
448
Step-by-step explanation:
aₙ = a₁ + (n-1)d
a₈ = a₁ + (8-1)d = a₁ + 7d
a₁₂ = a₁ + 11d
a₈ + a₁₂ = 246 = 2a₁ + 18d a₁ + 9d = 123
a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298 a₁ + 11d = 149
2d = 26
d = 13
a₁ = 6
a₃₅ = 6 + (35-1) x 13 = 448

Three runners are jogging from North Augusta to Beech Island. Runner 1 runs 14 miles in 3 hours while .Runner 2 runs 16 miles in 4 hours. Runner 3 runs 15 miles in 6 hours. What is the average speed of each runner?
Answer:
Runner 1,2 and 3 ran at a average speed of 4.67 , 4 and 2.5 miles per hour respectively
Step-by-step explanation:
We can all agree that speed equals distance divided by time and we are asked to find out the average speed of this 3 people.
---Average speed of runner 1
Speed = distance / time
Since he ran 14 miles within 3 hours
S = 14/3
The average speed was 4.67 miles pet hour
---For runner 2,
Speed = distance / time
Since he ran 16 miles in 4 hours,
Average speed = 16/4
= 4 miles per hour
---For runner 3,
Speed = distance / time
Since he ran 15 miles under 6 hours,
Average speed = 15/6
= 2.5 miles per hour

A circle's circumference is approximately 44 cm.
Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.
The circle's diameter is approximately cm.
The circle's radius is approximately cm.
The circle's area is approximately cm2.
these are all approximate
======================================
Explanation:
C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,
C = pi*d
d = C/pi
d = 44/3.14
d = 14.01 approximately
d = 14 also approximate
take half of this to get the radius
r = d/2 = 14/2 = 7
Then use this radius to find the circle's area
A = pi*r^2
A = 3.14*7^2
A = 153.86
A = 154 rounding to the nearest whole number
Answer:
Circle's radius
[tex]r=7.00\rm cm[/tex]
Circle's diameter
[tex]d=2r=2\times7=14\rm cm[/tex]
Circle's area
[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]
Step-by-step explanation:
Given information:
Circle's circumference is = [tex]44\rm cm[/tex]
We know,
Circumference of circle [tex]=2\times\pi\times r[/tex]
On substitution,
[tex]2\times3.14\times r=44\rm cm[/tex]
Circle's radius
[tex]r=7.00\rm cm[/tex]
Circle's diameter
[tex]d=2r=2\times7=14\rm cm[/tex]
Circle's area
[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]

Calculate Line AC showing working to 1dp
Answer:
18.1 cm
Step-by-step explanation:
Consider a segment parallel to CD and passing through B.
This segment will form a right-angle triangle with A
It's length would be equal to the length of CD (the missing length)
Height of that triangle:
11 - 4 = 7
CD² = 16² - 7²
CD² = 207
CD = sqrt(207)
AC² = AD² + CD²
AC² = 11² + 207
AC² = 328
AC = 2sqrt(82)

Write the equation of the circle graphed below
Answer:
[tex](x-1)^2+(y+1)^2=0.25[/tex]
Step-by-step explanation:
From the given graph it is clear that the center of the circle is (1,-1) and the circle passing through the point (0.5,-1).
So, radius of the circle is
[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(0.5-1)^2+(-1-(-1))^2}[/tex]
[tex]r=\sqrt{(-0.5)^2}[/tex]
[tex]r=\sqrt{(0.5)^2}[/tex]
[tex]r=0.5[/tex]
The radius of the circle is 0.5 units.
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where, (h,k) is center and r is radius.
The center of given circle is (1,-1) and radius is 0.5. So, the equation of circle is
[tex](x-(1))^2+(y-(-1))^2=(0.5)^2[/tex]
[tex](x-1)^2+(y+1)^2=0.25[/tex]
Therefore, the required equation is [tex](x-1)^2+(y+1)^2=0.25[/tex].

Given:
Given that the angles of the kite.
The opposite angles of the kite measures (3y + 14)° and (y + 50)°
We need to determine the value of y.
Value of y:
We know the property that the opposite angles are equal.
Thus, applying the property, we have;
[tex]3y+14=y+50[/tex]
Subtracting both sides of the equation by y, we have;
[tex]2y+14=50[/tex]
Subtracting both sides of the equation by 14, we get;
[tex]2y=36[/tex]
Dividing both sides of the equation by 2, we get;
[tex]y=18[/tex]
Thus, the value of y is 18.
