The probability of getting a blue marble is 0.15.
What is probability?The probability of an event is a number that indicates how likely the event is to occur.
Given that, a bag contains marbles of four different colors: 8 blue marbles, 24 red marbles, 16 green marbles and 4 yellow marbles,
We need to find the probability of picking a blue marble at random out of the bag,
Probability(Event) = Favorable Outcomes / Total Outcomes
Favorable Outcomes = 8
Total Outcomes = 52
Therefore,
P(blue marble) = 8/52 = 0.15
Hence, the probability of getting a blue marble is 0.15.

Answer:
Step-by-step explanation:
LHS
tan θ * cot θ
= sin θ / cos θ * cos θ / sinθ
= 1
RHS
sec θ * cos θ
= 1/cos θ * cos θ
= 1
Therefore LHS = RHS proved.

Answer: So, you got the length of side C. You now need to find what 10 is squared, then what plus what (in squared gates you there). A squared plus B squared is C squared. It is basic Pythagorean Threom.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For this I think you should know what SOH-CAH-TOA is, if not here.
O=opposite, A=adjacent(side), and H=-hypotenuse. We see they give us the right angle we need to solve, remember that we need the angle to the side of the right angle. Now S=sin, C=cos, T=tan, with these we use them to solve in the calculator. If you don't have a calculator, its going to be hard. But if you have a Ti-84 then set it to Degree mode. Ok moving on, We see they give us the adjacent and the hypotenuse, not the opposite.(from the given angle) So we can take off, SOH and TOA, see it doesn't have or has the incorrect sides. So we have left CAH.
Equation time:

There are 70 dogs and 55 cats at the shelter. 15 of these animals get adopted . What is the percent of the animals that got adopted
Answer: 12%
Step-by-step explanation:
Given
There are 70 dogs and 55 cats at the shelter
If 15 animals are adopted
Total no of animals =70+55=125
Percent of animals adopted is given by
[tex]\Rightarrow \dfrac{\text{Animals adopted}}{\text{Total animals}}\times 100\\\\\Rightarrow \dfrac{15}{125}\times 100=12\%[/tex]

can any one tell this answer with dafination and all steps
Answer:
(1, -1)
Step-by-step explanation:
Given the expression
x+y = 0 .....1
y = x²+2xy ....2
From equation 1, x = -y
Substitute into 3
y = x²+2xy
y = (-y)²+2(-y)y
y = y²-2y²
y = -y²
1 = -y
y = -1
Since x = -y
x = -(-1)
x = 1
Hence the required solution is (1, -1)
“28 is 40% of what number?” i got 70, is that correct?
Answer:
70
You got it correct :)
Step-by-step explanation:
[tex]\frac{28}{y} =\frac{40}{100}[/tex]
y × 40 = 100 × 28
40y = 2800
40y ÷ 40 = 2800 ÷ 40
y = 70
Select all statements that show correct reasoning for finding 15 ÷ 2/9 * Multiply 15 by 2, then divide by 9. Multiply 15 by 9, then divide by 2. Multiply 15 by 1/9, then multiply by 2. Multiply 15 by 9, then multiply by 1/2
Answer:
Multiply 15 by 9, then divide by 2.
Step-by-step explanation:
We need to solve the given expression.
[tex]15\div \dfrac{2}{9}[/tex]
We know that, [tex]a\div \dfrac{b}{c}=a\times \dfrac{c}{b}[/tex]
We have,
a = 15, b = 2 and c = 9
So,
[tex]15\div \dfrac{2}{9}=15\times \dfrac{9}{2}\\\\=\dfrac{15\times 9}{2}\\\\=\dfrac{135}{2}\\\\=67.5[/tex]
So, the steps are "Multiply 15 by 9, then divide by 2".

Law of sines:
sin(C)
C
Answer:
Step-by-step explanation:
''he Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.''
The best approximation value of a by using sine rule is 3.0cm. so option C is correct.
What is sine rule?The sides and angles of non-right triangles are related according to the Law of Sines.
The relationship between the angles and lengths of the sides:
a/sinA = b/sinB = c/sinC
We know according to law of sines:
a/sinA = b/sinB = c/sinC
by putting the values we can write,
a/sin40° = 4.7/sin95°
a = (4.7 ×sin40°)/sin95°
= 3.032
by putting the value of Sin40° and Sin95°.
we get a = 3.03cm.
Approximation value of a is 3.0cm.

mb- The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (2,100) and (4,200) to find the number of soda bottles the machine can make each minute
Answer:
1200
Step-by-step explanation:
We can gather from what's given that y=20xy represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.
