The true statement about the number of pets owned by the thirty adults is (b) The mean and median are both in the interval 6-10
What is an histogram?Histograms are graphs that are used to represent data, where the length of the bars represent the frequency
The data on the histogram are:
14 adults = 1-5 pets;
9 adults = 6 to 10 pets;
5 adults = 11 to 15 pets
2 adults = 16 to 20 pets
The mean is calculated as:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{14 * 3 + 9 * 8 + 5 * 13 + 2 * 18}{30}[/tex]
This gives
[tex]\bar x = 7.2[/tex]
7.2 is in interval 6 to 10
The median is:
[tex]Median = \frac n2[/tex]
[tex]Median = \frac {30}2[/tex]
[tex]Median = 15th[/tex]
The 15th element is also interval 6 to 10
Hence, the true statement is (b) The mean and median are both in the interval 6-10

THE ANSWER IS B EZZZZZ
Step-by-step explanation:
In ΔMNO, m = 780 inches, o = 760 inches and ∠O=164°. Find all possible values of ∠M, to the nearest degree.
Answer:
So the answer is both
180 and 328 (but it may or may not show you "not possible, if so, then you got it right)
Step-by-step explanation:
SinA/a= SinB/b
1. SinM/780 = Sin164/760
2. 780sin164/760 = 0.2828909704
3. M = sin^-1 (0.2828909704)= 16.4328229 or 16
Check for possibility
180-16= 164
164 + 16= 180 (not possible)
164 + 164= 328 (not possible)

a. Which plant was the tallest at the beginning?
b. Which plant had the greatest rate of change over the 6 weeks?
A. plant 3; plant 3
B. plant 1; plant 3
C. plant 2; plant 2
D. plant 3; plant 1
Answer:
A. plant 3; plant 3
Step-by-step explanation:
Plant 3 was the tallest at the beginning. We know this because it is the plant with the highest recorded height at time = 0.
Plant 1 grew 3.5 inches over 6 weeks.
Plant 2 grew ~ 2.25 inches over 6 weeks.
Plant 3 grew 4 inches over 6 weeks.
> This means that plant 3 grew the most, or had the greatest rate of change, over the 6 weeks.

A man is parasailing on a lake. The rope he is holding is 150 feet long and he is 45 feet above the water. What is the horizontal distance between the man and the boat? Round your answer to the nearest tenth.
9514 1404 393
Answer:
143.1 ft
Step-by-step explanation:
Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.
150² = 45² + d²
d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet
The horizontal distance between the man and the boat is about 143.1 feet.
Cual es el volumen del concreto que necesitamos para construir cuatro columnas circulares si el diámetro de cada una es de 50 cms y la altura y la altura son 3,5(la respuesta en ms)
Answer:
27488.92 cm³
Step-by-step explanation:
El volumen de concentre para columna circular = área de superficie del círculo × altura de la columna.
= πr² × h
Dado que:
diámetro = 50 cm
height = d/2 = 50 cm / 2 = 25 cm
= 3.5 cm
Entonces:
El volumen de concentre para columna circular = πr² × h
El volumen de concentre para columna circular = π(25)² × 3.5
El volumen de concentre para columna circular = 6872.23 cm³
Para cuatro columnas circulares; el volumen será: = 4 × 6872.23 cm³
= 27488.92 cm³

(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0

Write an exponential function whose graph passes through
the points (0, -3) and (4, -48)
Answer:
[tex]y = -3(2^{x})[/tex]
Step-by-step explanation:
y = [tex]kb^{x}[/tex]
Use (0, -3) to find k
[tex]-3 = kb^{0} = k(1) = k\\[/tex]
So, k = -3
Now use (4, -48) to find b
-48 = [tex]-3b^{4}[/tex]
[tex]b^{4}[/tex] = 16
b = 2
Since k = -3 and b = 2, [tex]y = -3(2^{x})[/tex]

A bicycle tire makes 40 full revolutions while traveling where Scott is standing to where Steve is standing. If a tire has a diameter of 20 inches what is the approximate distance between where Steve is standing?
Answer:
2513.27 inches
Step-by-step explanation:
Given that:
Diameter = 20 inches
Number of revolutions = 40
For a complete revolution :
Distance traveled = Circumference = 2πr
2 * π * 20/2 = 62.831853 inches
Distance per revolution * number of revolutions
62.831853 * 40
= 2513.2741 inches
= 2513.27 inches
f(x)=x2 + 4x -6
f(x) can be written in the form (x + m)?+n.
Find the value of m and the value of n.
Answer:
m = 2 and n = -10
Step-by-step explanation:
The given function is f(x) = x² + 4·x - 6
The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation
We have;
f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4
f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10
f(x) = (x + 2)² - 10
By comparison with (x + m)² + n, we have;
m = 2, and n = -10

A building has 816 feet tall and it has 102 floors, each floor is the same height. How tall is each floor?
Answer:
8 feet tall
Step-by-step explanation:
Divide 816 by 102 to get 8 feet.
Answer:
The hight of each floor is 8(ft).
Step-by-step explanation:
If you divide 816(ft) by 102 floors you will get 8(ft) making each floor 8(ft) because the building's hight divided by the floors would make an amount of the hight of each floor.
