Answer:
a) green: 0.3
yellow: 0.1
b) 12
Step-by-step explanation:
Unfortunately, I cant write on the table. But, I CAN help you with this question.
Since all probabilities have to add up to one, we can for an equation like this
(where y is yellow)
0.35+0.25+3y+y=1
This simplified is
0.6+4y=1
4y=0.4
So, we now know that green is 0.3, and yellow is 0.1.
For b, we set 0.35x to 14. Dividing gives us:
14/0.35=1400/35=40.
Multiply 0.3 by 40, and you get 12.

From the information given, what is the biggest flaw in the study? A health researcher randomly selected 500 high school students from the city of Oak Grove. In a private interview the researcher asked the students whether they had ever used drugs. She concluded that only 8% of the high school students of Oak Grove have ever used drugs.
Answers
Answer:
The correct answer is - The setting may discourage honest responses.
Step-by-step explanation:
In this particular setting of research and interview regarding this research may not produce hones results as the question is too direct to ask students if they had ever used drugs.
Research should be anonymous and should avoid the questions that can lead to bias results like this case that may lead to dishonest results.
Thus, the correct answer is : The setting may discourage honest responses.

Step-by-step explanation:
We can just substitute the numbers (x, y) into the inequality to see if the inequality is valid.
y=40
5(4) + 8 = 28
"<" means the number on the left is smaller than the number on the right.
40 is not smaller than 28, so in this inequality,
(4, 40) is not valid in y<5x+8
Find the value of x in the triangle
shown below.
Answers
Answer: 55
Step-by-step explanation:
There are two sides that are equal (5 and 5). That means that this is an isoceles triangle. The unmarked angle and the x angle are equal to each other because isoceles triangles have also have two equal angles. Because every triangle has 180 degrees, that means that all three angles added up should equal 180.
Since the unmarked and x angle are equal you can write the equation out as 180=70+2x. Subtract 70 from both sides to get the variable and nonvariable on different sides.
110=2x. Divide both sides by 2(in order to isolate the variable). X is 55

What are the zeroes of f(x) = x2 − 6x + 8? (4 points) x = −4, 2 x = −4, −2 x = 4, 2 x = 4, −2
Answers
Hey there! :)
Answer:
Third option. x = 2, and x = 4.
Step-by-step explanation:
Find the zeros of this quadratic equation by factoring:
f(x) = x² - 6x + 8
Becomes:
f(x) = (x - 4)(x - 2)
Set each factor equal to 0 to solve for the roots;
x - 4 = 0
x = 4
x - 2 = 0
x = 2
Therefore, the zeros of this equation are at x = 2, and x = 4.
Answer:
x=4 x=2
Step-by-step explanation:
f(x) = x^2 − 6x + 8
To find the zeros, set equal to zero
0 = x^2 − 6x + 8
Factor
What 2 numbers multiply to 8 and add to -6
-4*-2 = 8
-4+-2 = -6
0 = ( x-4) (x-2)
Using the zero product property
x-4 =0 x-2=0
x=4 x=2

Answers
Answer:
B = {(5, 3), (−2, −9), (−3, 8), (9, 3)}
Step-by-step explanation:
A function has no repeating inputs (x-values). One input is assigned to exactly one output.
In set 'A', the input of two is repeated.
A = {(2, 7), (1, −5), (7, 2), (2, −9)}
In set 'B', there are no repeating inputs.
Set 'B' is a function.

Mrs smith invests £30,000 (some in a 5% account, some in an 8% account). After the year shes earned £2100. How much did she put in each account? PLEASE HELP!!
Answers
Answer:
She deposited £10,000 in the 5% yield account and deposited £20,000 in the 8% yield account
Step-by-step explanation:
Let the amount she put in each account be £x and £y respectively
Total amount deposited is ;
x + y = 30,000 ••••••(i)
Now, let’s look at the earnings:
in the £x , amount earned would be;
5/100 * x = 5x/100
For the £y, amount earned would be;
8/100 * y = 8y/100
Adding both gives the total which is £2,1000
5x/100 + 8y/100 = 2,100
Multiply through by 100
5x + 8y = 210,000 ••••••••(ii)
From the first equation, we know that
x = 30,000 -y
Let’s put this into the second
5(30,000-y) + 8y = 210,000
150,000-5y + 8y = 210,000
3y = 210,000 -150,0000
3y = 60,000
y = 60,000/3
y = £20,000
So mathematically;
x = 30,000-y
x = 30,000 -20,000
x = £10,000

Answers
Answer:
Option B.
Step-by-step explanation:
The general equation of best fit line is
[tex]y=ax+b[/tex]
where, a is the slope of best fit line and b is y-intercept.
Using graphing calculator a=-4.54762 and b=43.7143. So equation of best fit line is
[tex]y=-4.54762x+43.7143[/tex]
Here,
[tex]Slope=-4.54762[/tex]
[tex]Slope\approx -4.5[/tex]
Note: In alternate method, you can use the below formula to find slope.
[tex]m=\dfrac{\overline{x}\cdot \overline{y}-\overline{xy}}{(\overline{x})^2-\overline{x^2}}[/tex]
Therefore, the correct option is B.
Answer:
B: -4.5

Write a detailed paragraph answering the following: 'Belief in life after death doesn’t make sense in our modern world’ Evaluate this statement. Write one paragraph arguing for or against this statement, keeping to Point Evidence Explain
Answers
Answer:
It seems impossible to figure out what comes after death, since none of us can return from the other side of that curtain, nor can we interview those who have already died.Yet belief in life after death is both timeless and global. Almost every culture believes in an afterlife. Belief in life after death runs especially high in non-Western countries, but even in America it runs as high as 75 percent. Only in parts of Asia and Europe is belief in an afterlife an uncommon view. Atheists who deny both God and an afterlife may be vastly outnumbered, but they think they occupy the intellectual high ground on this question. That's because religious believers typically affirm the afterlife on the basis of faith, while atheists regard themselves as denying it on the basis of science and reason.

Sonya made a graph showing the first ten minutes of her drive to the movies. A graph with time on the x-axis and speed on the y-axis. The graph increases, increases rapidly, and then remains constant. Which description is the best interpretation of the graph? Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway. Sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. She stopped the car. Sonya drove down her driveway at a constant speed until she reached the street. She turned and drove down the street at a constant speed. Her car went slower as she drove up a hill. At the top of the hill she drove into the parking lot of the movie theater. Sonya accelerated as she drove down her driveway. She accelerated on the street on her way to the highway entrance. She waited for a red light, then accelerated onto the highway.
Answers
Answer:
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
Step by step explanation:
The first scenario is the best match for the increasing slope, (leaving the house and accelerating) rapidly increasing slope (increasing speed on ramp) and level line (constant speed on the highway).
The best interpretation of the graph is,
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
What is Acceleration?When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
Here, we have,
The first scenario is the best match for the increasing slope, (leaving the house and accelerating) rapidly increasing slope (increasing speed on ramp) and level line (constant speed on the highway).
Hence, The best interpretation of the graph is,
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of the tree is 20.6257 feet.
What is Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The digram for the given condition is given below. Now, in ΔABC, the tangent value for ∠A can be written as,
tan(38°) = BC/AB
tan(38°) = 5 feet / AB
AB = 6.3997 feet
Now, in ΔABC and ΔADE for ∠A the value of the tangent can be written as,
tan(38°) = BC/AB = ED/AD
5/6.3997 = ED/(20 + 6.3997)
ED = 20.6257 feet
Hence, the height of the tree is 20.6257 feet.
