Which statement is correct regarding independent events?
OTwo events are independent if they have no outcomes in common and cannot occur at the same time.
OTwo events are independent if they have outcomes in common and can occur at the same time.
OTwo events are independent if the outcome of the first event does not affect the outcome of the second event.
O Two events are independent if the outcome of the first event affects the outcome of the second event.
Answer:
Two events are independent if the outcome of the first event does not affect the outcome of the second event.
Step-by-step explanation:
two events are independent if the occurrence or outcome of the first event does not affect the outcome or occurrence of the second event.
for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events
two outcomes are dependent if the outcome one event is determined by the outcome of the first event.
The graph represents the number of bike paths planned for the cities of Nashville and Houston. The number of paths to be built in Houston is modeled by y = 4(2)x, and the number planned for Nashville is modeled by y = 4x. According to the graph, which statement is true about this situation? A) The number of paths planned for Nashville is increasing exponentially. B) The number of paths planned for Houston is represented by the green line. C) The number of paths planned for Nashville is represented by the green line. D) The number of paths planned for Nashville will more than likely exceed the paths in Houston as the value of x increases.
Answer:
C
Step-by-step explanation:
Answer:
C. The number of paths planned for Nashville is represented by the green line.
Step-by-step explanation:
Nashville is y=4x, so if you graph that in desmos, you will see the line for Nashville is the same as the green line in the question.
A rectangular fish tank is 22 inches tall. The base edge lengths are 20 inches and 18 inches. What is the total surface area of the fish tank?
Answer:
2392in^2
Step-by-step explanation:
Given data
Dimension
Height 22 inches
Lenght= 20inches
Width= 18inches
The expression for the total surface area is
TSA=2(lw + lh + wh)
Substitute
TSA=2(20*18+20*22+18*22)
TSA=2(360+440+396)
TSA=2*1196
TSA=2392 in^2
Hence the total surface area is 2392in^2
A right triangle is shown below.
Х
4
8.5
What is the value of x? Enter your value as a decimal rounded to the nearest tenth,
Step-by-step explanation:
Use the Pythagorean Theorem ( [tex]a^{2}+b^{2} =c^{2}[/tex] )
The longest side is c = the hypotenuse, and a and b = the other sides of the triangle.
a = 4 First: [tex]4^{2}+x^{2}=8.5^{2}[/tex]
b = x Second: [tex]16+x^{2}=72.25[/tex]
c = 8.5 Third: [tex]x^{2}=56.25[/tex]
Fourth: [tex]x=\sqrt{56.25}[/tex]
Fifth: x = 7.5
If 1/5 = 2/3, then ?/5 = 3/3. Show your work and explain your reasoning.
Answer:
3/10
Step-by-step explanation:
If 1/5 = 2/3 then 1/10 = 1/3
So given that information, 3/10 = 3/3

can somebody find the volume of the cone on #2?
thank you!!
Answer:
[tex] 4,220.16 \: {units}^{3} [/tex]
Step-by-step explanation:
Diameter of cone = 24 units
Radius of cone (r) = 24/2 = 12 units
Height of cone (h) = 28 units
[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} [/tex]

Answer:
The y-int represents the base price of $200 for airfare from NYC
The slope represents a cost of 30 cents per mile traveled
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x
If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x

Answer:
x = 30
Step-by-step explanation:
since 2 sides are equal, that means their angles are also equal.
you do 180-120 to get 60 and then divide 60 by 2 to get 30
Answer:
x=30
Step-by-step explanation:
We know all the angles a triangle combined are 180 the two bottom angles for this one are equal so we can do
(180-120)/2=30

Answer:
1, 2, -3, 51
Step-by-step explanation:
0 ÷ 2 = 0, then + 1 = 1
2 ÷ 2 = 1, then + 1 = 2
-8 ÷ 2 = -4, then + 1 = -3
100 ÷ 2 = 50, then + 1 = 51

AB and CD are straight line segments.
∠ AOE = 50° and ∠ DOB = 95°.
Find the values of the following angles giving a reason for each answer in the comment box.
The diagram is not drawn accurately.
i) obtuse ∠ AOC
ii) acute ∠ BOC
iii) acute ∠ DOE
Answer:
i) Angle AOC is 95° Reason:- Angle AOC is equal to Angle DOB since they are Vertically Opposite Angles.ii) Angle BOC is 85° Reason:- Angle AOC + Angle BOC - 180° (they lie in a straight line so they are a linear pair. Sum of the angles will be 180°) Angle AOC is 95°, So:- 95° + Angle BOC = 180° Angle BOC= 180° - 95° Angle BOC = 85° iii) Angle DOE is 17° Reason:- Angle AOE+ Angle DOE+ Angle DOB = 180° (they lie in a straight line so they're a linear pair. Sum of the angles will be 180°) So, 68° + Angle DOE+ 95° = 180° 163° + Angle DOE = 180° Angle DOE= 180° - 163° Angle DOE is 17°
A basketball team won 72.5% of their games. Find the probability they win 16 if their next 30 games.
Answer:
0.00987
Step-by-step explanation:
Using binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
p = 0.725 ; number of trial, n = 30
Number of winning, x = 16
1 - p = 1 - 0.725 = 0.275
P(x = 16) = 30C16 * 0.725^16 * 0.275^14
P(x = 16) = 119759850 * 0.725^16 * 0.275^14
P(x = 16) = 0.00987
Hence, the probability of winning 16 of their next 30 games is 0.00987

A factory worker loaded some boxes onto a cart . Each box has the same weight . This expression represents the total weight in pounds , of the cart and n boxes 10n + 25 Based on the expression , what is the weight , in pounds , of the cart ?
Answer:
25 pounds
Step-by-step explanation:
Sum of the weight of the boxes of the cart = 10n + 25
where n = number of boxes
10 would be the weight of each box.
total weight of the boxes = weight of each box x number of boxes
10 x n = 10n
The other variable is 25. this is the weight of the cart
