Answer:
4,000
Step-by-step explanation:
To round a number, take the place next to the one you wish to round and look to see if it is four or under, or five or up. In this case, 2 is less than 5 so we will be rounding down towards the nearest integer, which is 4. Also, all places after the place value you round will become zero. So, 4,000 rounded to the thousands place is 4,000.
hope this helps :)
Answer:
The answer would be 4,000
Step-by-step explanation:
even if you round it up the the nearest hundred, it would still be 4,000.

Richard and Cameron buy a carton containing 6 66 eggs. The back of the carton says, "The expected number of broken eggs per package is 0.12 0.120, point, 12." Richard says, "The probability that one of these cartons contains a broken egg is 0.12 0.120, point, 12, on average." Cameron says, "For every 100 100100 packages like this, we'd predict about 12 1212 broken eggs in total." Whose statement is correct based on the expected value?
Using the binomial distribution, it is found that Cameron's statement is correct based on the expected value.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np.
In this problem, we have that:
The probability of a package containing a broken egg is of p = 0.12.There is a sample of 100 packages, hence n = 100.Thus, the expected value is given by:
E(X) = np = 100 x 0.12 = 12.
Hence, Cameron's statement is correct.

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as kim's fish
Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish. So, Doug caught a fish that was 3/5 meters long.
What is the fundamental principle of multiplication?
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways
Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish.
Kim caught a fish of length = 9/10 m
Doug caught a fish of length = 2/3 as long as Kim's fish.
= 2/3 x 9/10
= 18 / 30
= 3/5
Thus, Doug caught a fish that was 3/5 meters long.

A company makes an ice-cream treat in the shape of a hemisphere on top of a cone, as shown below.
2 cm
10 cm
Answer:
56/3 pi cm^3
Step-by-step explanation:
1/2 volume of sphere = 1/2 4/3 pi r^3
volume of cone 1/3 pi r^2 h
r =2 h = 10
result : 56/3 pi cm^3
The volume of the ice cream is 58.64 cubic cm.
What is a three dimensional figure?A three dimensional figure has three dimensions as length, breadth and height. The volume of a three dimensional figure is the amount of the substance contained by it.
Given that,
The height of cone part of the ice cream is h = 10 cm.
The radius of the hemisphere is r = 2 cm.
As per the diagram given the radius of the hemisphere is equal to the radius of cone as 2 cm.
The volume of hemisphere is given as (2/3) × πr³.
And, the volume of cone is given as (1/3) × πr²h.
Now, the volume of the ice cream treat is equal to the sum of the volume of cone and hemisphere as,
V = (1/3) × π × r²h + (2/3) × π × r³
Substitute the values to get,
V = (1/3) × π × 2² × 10 + (2/3) × π × 2³
= (56/3) × π
= 58.64
Hence, the volume of the ice cream treat is 58.64 cubic cm.

Answer:
16
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Alright so:
-172 = -11x + 4
-4 - 4 (-4 on both sides)
so,
-176 = - 11x
divide by -11
so,
-11x ÷ - 11 = x
-176÷-11= 16

Tell whether the ordered pair is a solution of the linear system.
(4, -1)
x + 2y = 2
x - 2y = 6
Answer:
(4,-1) is a solution
Step-by-step explanation:
x + 2y = 2
x - 2y = 6
We want to see if (4,-1) is a solution to the system.
To do so we plug in x = 4 and y = -1 into both equations and if it is true then the ordered pair is a solution but if one of the equations isn't true then the solution isn't a solution
x + 2y = 2
==> plug in x = 4 and y = -1
4 + 2(-1) = 2
==> multiply 2 and -1
4 - 2 = 2
==> subtract 2 from 4
2 = 2
x - 2y = 6
==> plug in x = 4 and y = -1
4 - 2(-1) = 6
==> multiply -2 and -1
4 + 2 = 6
==> add 4 and 2
6 = 6
Both equations are true therefore (4,-1) is indeed a solution to the system
Use the discriminant to determine how many and what kind of solutions the quadratic equation x^2 - x = 1 has.

4. two real solutions

Equating it with [tex]ax^2+bx+c=0[/tex]We find: a = 1, b = -1, c = -1Next, we calculate the discriminant of the given quadratic equation by plugging the values of a, b and c in the formula [tex]\implies b^2-4ac[/tex][tex]b^2-4ac\\=(-1)^2-4(1)(-1)\\=1+1=2>0\\\implies b^2-4ac >0[/tex]

A skateboarder leaves a 12-foot tall ramp with an initial vertical velocity of 8 feet per sen
function f(h) = -8t² +8t + 12 represents the height, h, in feet of the skateboarder after t seconds.
How many seconds was the skateboarder airbound
To answer this, we substitute 12 ft to the f(h) in the given equation,
f(h) = -8t² + 8t + 12 = 12
Subtracting 12 from both sides of the equation will give us an answer of,
-8t² + 8t = 0
Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second.
Answer:
Below in bold.
Step-by-step explanation:
When he lands h = 0 so
-8t^2 + 8t + 12 = 0
Solving for t
t = [-8 +/- sqrt(8^2 - 3*-6*12)] / -16
t = 1.82 seconds.

Answer: y= -1/20x + 38/5
or
y= -1/20x + 7.6
Step-by-step explanation:
y-y1 = m(x-x1)
m = 8-7 / -8 - 12 = 1/-20 = -1/20
y-8 = -1/20(x+8)
y=-1/20x - 8/20 + 160/20
y= -1/20x + 38/5
or
y= -1/20x + 7.6
