Answer:
1 / 3
Step-by-step explanation:
Number of balls :
Red, R = 3 ; Blue, B = 2 ; Yellow, Y = 1
Total = 6
From two draws without replacement, probability that 2nd draw is blue :
Possibilities :
P(RB) or P(YB) or P(BB)
P(RB) = 3/6 * 2/5 = 6/30
P(YB) = 1/6 * 2/5 = 2 /30
P(BB) = 2/6 * 1/5 = 2 / 30
HENCE,
P(RB) + P(YB) + P(BB)
6/30 + 2/30 + 2/30 = 10/30 = 1/3
who can do this and how?
Answer:
C
Step-by-step explanation:
If we round up the 3/4 cup of sugar to 1 cup to make it easier, and then multiply by 2 because the 3/4 cup of sugar only makes half a dozen cupcakes, then we will get 2 cups of sugar which is an overestimate of how much is needed. If we multiply it again by 3 because he needs 3 times the amount of sugar, we get 6 cups of sugar because we rounded it up. Since we know 3/4 is less than 1, we can assume that 6 cups of sugar is more than needed.
O a Olivia went to a dance party. She paid $12 as an entry fee. Once inside the dance party, she paid $2 per snack. She started the night with $30 and spent all her money.
which of the following represents an equation that could be used to model this situation?
A) 2x +12=30
B) 30+2x+12=0
C)2x -12= -30
D)30/2x =12
Answer: 2x + 12 = 30
12 is the initial fee, then x is the unknown variable. Since each snack costs 2 dollars, and we don't know how many she had, we can use the equation:
2x + 12 = 30

snack initial total
fee fee $ spent
Beth went shopping and withdrew an anverage of 25$ from her account every hour for 6 hours. What was the change in her account
Answer:
To solve this question we are going to multiply. So lets say that h represents hours, in this equation we have 6 hours, so 6h Beth spent 25 dollars per hour for 6 hours so we can substitute the h in 6h with 25, which will result in us multiplying,
6h
6(25)
= 150

can someone pls help!!
Answer:
see screenshot 1.
feel free to copy the graph.
f(0)=-5
notice that anything to the power of zero is one (because its dividing by itself). so we are left with A, -5
f(1)=-10
notice that anything to the power of 1 is just itself, so we multiply-5 by 2 here
A is negative, so the graph will be facing down
the value of B is is greater than 1, meaning the graph will be growing [down].
Part B

Hey can anyone help me I am really stuck, Use exact values. NO DECIMALS they say
Answer:
x = 8
y = 4 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 30 = 4/x
x sin 30 = 4
x = 4 / sin 30
x = 4 / ( 1/2)
x = 8
tan theta = opp /adj
tan 30 = 4/y
y tan 30 =4
y = 4 / tan 30
y = 4 / ( 1/ sqrt(3))
y = 4 sqrt(3)
Answer and Step-by-step explanation:
To solve, we need to use Trigonometric Functions.
These functions include Sine, Cosine, and Tangent.
- Each one has its own rule to follow when solving.
θ = Angle
sin(θ) = [tex]\frac{Opposite.Side}{Hypotenuse}[/tex]
cos(θ) = [tex]\frac{Adjacent.Side}{Hypotenuse}[/tex]
tan(θ) = [tex]\frac{Opposite.Side}{Adjacent.Side}[/tex]
For this problem, we will only be using the trigonometric functions of Sine and Tangent.
Start by finding x.
sin(30) = [tex]\frac{4}{x}[/tex]
Multiply x to both sides.
x × sin(30) = [tex]\frac{4}{x}[/tex] × x
x(sin(30)) = 4
Divide both sides of the equation by sin(30).
x(sin(30)) ÷ (sin(30)) = 4 ÷ (sin(30))
x = [tex]\frac{4}{sin(30)}[/tex]
Simplify in calculator.
x = 8
Now find the value of y.
tan(30) = [tex]\frac{4}{y}[/tex]
Multiply y to both sides.
y × tan(30) = [tex]\frac{4}{y}[/tex] × y
y(tan(30)) = 4
Divide both sides of the equation by tan(30).
y(tan(30)) ÷ (tan(30)) = 4 ÷ (tan(30))
y = [tex]\frac{4}{tan(30)}[/tex]
Simplify in calculator.
y = [tex]4\sqrt{3}[/tex]
x = 8
y = [tex]4\sqrt{3}[/tex]
^ These are the answers.

Answers:
11. D) There appears to be an association between the variables. Since the teams with animal mascots win 74% of their games played and those with another type of mascot only win 49% of their games, the large difference suggests an association.12. A) 913. D) There appears to be an association. Since there is a difference in percentages for modern and classical styles for the type of art.14. D) 59%15. A) 60%=================================================
Explanations:
11. If the columns were identical (or nearly so) then that would suggest there isn't any association. However, the columns are different so it's likely we have association going on. Changing the mascot type appears to have an effect on whether the team wins or loses. In other words, the variables appear to be dependent.12. Let x be the missing value in the table. Solve the proportion x/18 = 27/54 and you should get x = 9. If 9 goes in that table, then it will produce identical row relative frequencies (and identical column relative frequencies as well) which would then lead us to conclude that there probably isn't any association between the variables.13. This is similar to problem 11. The columns being different percentages shows that changing the art style changes the make up of the sculptures and paintings. 14. There are 37+54 = 91 people who prefer the beach (instead of skiing). Of this total, 54 are away from the coast. So roughly 54/91 = 0.59 = 59% of the beach-goers are away from the coast.15. Same idea as the previous problem. We have 24+36 = 60 people who like to ski, and 36 people are away from the coast. So 36/60 = 0.60 = 60% of the skiers are away from the coast.The function f(x) = –x2 – 4x + 5 is shown on the graph.
On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 2, 9), and goes through (1, 0).
Which statement about the function is true?
The domain of the function is all real numbers less than or equal to −2.
The domain of the function is all real numbers less than or equal to 9.
The range of the function is all real numbers less than or equal to −2.
The range of the function is all real numbers less than or equal to 9.
Answer:
the last one : the range of the function is all real numbers less than our equal to 9.
Step-by-step explanation:
it is a parabola that opens up only down. that means all the calculated y-values go deeper and deeper into lower and negative values the more right or left we go on the x-axis.
the maximum y-value we have at the vertex with y=9. no other x-value can generate a bigger y-value.
that's why the last answer option is right.

Answers:
Choice B) y = (1/4)xThe unit rate is 3.89 dollars per pound. It costs 23.34 dollars for a turkey that weighs 6 pounds.=====================================================
Explanations:
Direct proportional equations are always in the form y = kx, where k is some constant. In the case of choice B, we have k = 1/4. Visually, direct proportion equations are always straight lines and go through the origin.Divide $34.99 over 9 to get 34.99/9 = 3.88777 approximately. This rounds to 3.89, so it costs $3.89 per pound. That's the unit rate. Multiply this by 6 to get 6*3.89 = 23.34 which is the cost of the 6 pound turkey.Answer:
1) B
2) 17 1/3
Step-by-step explanation:
1)
It's B because a proportional relationship doesn't add a number at the end.
It's on y = kx, where k = 1/4 in this case.
2)
9x = 35
x = 3 8/9

A rectangle has a length of 5/16 inches and a width of 25 inches. Find the area of the rectangle. (2 points)
Answer:
2
Step-by-step explanation:
The area of a triangle is equivalent to its length multiplied by its width.
In this example, one way we can look at this is to make everything in terms of two. First, we know that
[tex]2^{4} = 16\\\sqrt[5]{2^{4}} = \sqrt[5]{16} \\2^{4 (1/5)} = \sqrt[5]{2^{4}}[/tex]
We can establish that last line because x^((y)^(z)) = x^(y*z), as is stated in exponent rules. Therefore, our area is
[tex]2^{4/5} * 2^{1/5} = 2^{4/5 + 1/5} = 2^{5/5} = 2^{1} =2[/tex]

What is a right-angled triangle?
A triangle in which one of the interior angles is 90° is called a right-angled triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
According to the given problem,
Perpendicular = 8.8
Base = x
Let the Hypotenuse be h,
∅ = 72°
We know,
sin∅ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
⇒ sin72 = [tex]\frac{8.8}{h}[/tex]
⇒ 0.95 = [tex]\frac{8.8}{h}[/tex]
⇒ 0.95h = 8.8
⇒ h = [tex]\frac{8.8}{0.95}[/tex]
⇒ h = 9.3
Now, applying Pythagoras theorem,
Hypotenuse² = Perpendicular² + Base²
⇒ 9.3² = 8.8² + x²
⇒ 9.3² - 8.8² = x²
⇒ x² = 9.05
⇒ x = √9.05
⇒ x = 3
Hence, we can conclude the value of x to be 3.

At the middle avenue school 1/30 of the students are on track team the track coach offered to buy pizza or subs for everyone on the team Of the students whom the coach bought food 3/5 ordered pizza what fraction of students at middle avenue school are pizza
Answer:
[tex]Students = \frac{1}{50}[/tex]
Step-by-step explanation:
Given
[tex]Track = \frac{1}{30}[/tex]
[tex]Pizza = \frac{3}{5}[/tex]
Required
The fraction of students in the school that ate Pizza
To do this, we simply multiply the fraction of track students and those among them that ordered pizza.
So, we have:
[tex]Students = Pizza * Track[/tex]
[tex]Students = \frac{3}{5} * \frac{1}{30}[/tex]
[tex]Students = \frac{1}{5} * \frac{1}{10}[/tex]
[tex]Students = \frac{1}{50}[/tex]
What are the coordinates of the point on the directed line segment from (-6, -1)(−6,−1) to (6, -9)(6,−9) that partitions the segment into a ratio of 3 to 1?
Given:
A segments is from (−6,−1) to (6, -9).
A point divides the line segment into a ratio of 3 to 1.
To find:
The coordinates of the points.
Solution:
Section formula: If a point divides a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
The point divides the line segment in 3:1, so by using section formula, we get
[tex]Point=\left(\dfrac{3(6)+1(-6)}{3+1},\dfrac{3(-9)+1(-1)}{3+1}\right)[/tex]
[tex]Point=\left(\dfrac{18-6}{4},\dfrac{-27-1}{4}\right)[/tex]
[tex]Point=\left(\dfrac{12}{4},\dfrac{-28}{4}\right)[/tex]
[tex]Point=\left(3,-7\right)[/tex]
Therefore, the coordinates of the required point are (3,-7).
