Answer:
8411.67 m³
Step-by-step explanation:
The volume of a pyramid is one third its height times the area of its base. The Louvre pyramid has a height of 20.6 meters and a square base with sides of 35 meters. Find its volume, rounded to the nearest hundredth. Include units in your answer.
Volume of a pyramid is given as:
1/3 × Height × Area of it's base
= 1/3 × 20.6m × (35 m)²
= 8411.6666667 m³
Approximately = 8411.67 m³
Therefore, the volume of the pyramid = 8411.67 m³
The governor of Florida would like to estimate the mean age of all Florida residents. To do so, he randomly selects 500 Florida residents and determines their mean age to be 58.2 years. However, according the most recent census data, the mean age of all Florida residents is 55.6 years. Which of the following properly describes the number 58.2?
sample
statistic
population
parameter
Answer:
Sample
Step-by-step explanation:
Just took on Edge.
Sample describes the number 58.2 in the given problem.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A sample is a subset of individuals or items selected from a population, and statistics are values calculated from a sample.
As given, the governor of Florida randomly selected 500 Florida residents and determined their mean age to be 58.2 years.
This value is a sample statistic because it is calculated from a sample of individuals and is used to estimate a population parameter.
The number 58.2 represents a sample statistic.
Hence, sample describes the number 58.2 in the given problem.

what is the x intercept of a line that has a slope of 2/3 and passes through the point (-2,2)?
Answer:
-3
Step-by-step explanation:
use the equation y = mx + b where m is the slope and b is the y-intercept so just plug in what you know. y = 2/3x + 2 then solve the equation for x . To do that, just put y = 0 so then it would be -2 = 2/3x then -2/ 2/3 = x and -2 divided by 2/3 would be -3
A cylinder has a height of 19 centimeters and a radius of 10 centimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer: 5966cm³
Step-by-step explanation:
The volume of a cylinder is calculated using the formula:
Volume = πr²h
where, π = 3.14
radius = 10cm
Height = 19cm
Volume = πr²h
= 3.14 × 10² × 19
= 3.14 × 100 × 19
= 5966.00cm³

THE NUMBER 1-10 ARE IN A BAG, YOU TAKE 2 OUT WITHOUT REPLACEMENT. WHAT IS THE PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER.
Answer:
1 / 18
Step-by-step explanation:
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = Number of favorable outcome / Total number of outcomes
Favorable outcome = 1
Total number of outcome (1,2,3,4,5,6,7,8,9,10) = 10
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = 1 / 10
PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = Number of favorable outcome / Total number of outcomes
Favorable outcome (2,4,6,8,10) = 5
Total number of outcomes (1,2,3,4,5,6,8,9,10) = 9
PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = 5/9
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER = 1 / 10 * 5 / 9 = 1 / 18

Is this right with the equation given on the top ? If not what do I need to change ? GIVING BRAINLIEST
Answer:
no
Step-by-step explanation:
the slope is the angle of the line. to make this easier, I normally imagine rise/run. rise being the y axis and run being the x axis. if we change -3 to a fraction, it is -3/1. this basically means that from any given point, you go down 3 units, and over 1.
replace the (-3,0) point with a (3,1) point and it should be fixed.

Answer:
24m^2
Step-by-step explanation:
to get the length, we have to follow this equation:
2W + 2L = P
2(4) + 2L = 20
8 + 2L = 20
8 + 2(6) = 20
to get the area from this information, we have to follow this equation:
A = W • L
A = 4 • 6
A = 24m^2

A line with a slope of -1 passes through the point (5,6). What is its equation in point-slope form?
Answer:
y - 6 = -(x - 5)
Step-by-step explanation:
Start with the general point-slope form y - k = m(x - h).
Here m = -1, h = 5 and k = 6, and so, after substitutions, we have:
y - 6 = -(x - 5)

It is a GP because the ratio between two consecutive terms are same..
Here,
First term: [tex]a = 2[/tex]
Common ratio: [tex]r=\dfrac{a_2}{a_}[/tex]
[tex]r=\dfrac{4}{2}[/tex]
[tex]r=2[/tex]
The explicit formula of GP is:
[tex]a_n=ar^{n-1}[/tex]
Putting [tex]a=2,r=2[/tex], we get
[tex]a_n=2(2)^{n-1}[/tex]

Find the slope. (4, 10) and (-2,-5)
Answer:
Slope in fraction form = 5/2
Slope in decimal form = 2.5
========================================================
Work Shown:
m = (y2-y1)/(x2-x1)
m = (-5-10)/(-2-4)
m = (-15)/(-6)
m = (-3*5)/(-3*2)
m = 5/2 slope in fraction form
m = 2.5 slope in decimal form
-----------------
Explanation:
The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.
I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)
The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".
Or you can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
