what is the value of x in the proportion
Answer:
5 2/5
Step-by-step explanation:
Multiply by (3 3/5)x/(1 1/2):
x = (2 1/4)(3 3/5)/(1 1/2) = (9/4)(18/5)(2/3) =27/5
x = 5 2/5
a survey of 800 people who binge-watch were asked how many episodes is too many to watch in one viewing session. the results are displayed in the bar graph. explain how this graph is misleading
Answer:
The graph is misleading because the vertical scale is not even. It goes from 0 to 15 and then thereafter the scale reverts to a scale of 5.
This is misleading because had the graph gone in a scale of 5 from the get go, the number of people who thought 3-4 episodes were too much would have looked higher in the graph as they seem to comprise of about 5% of the sample population.
The scale should begin at 0 and then go like 5 ⇒ 10 ⇒ 15 ⇒ 20 ⇒ 25 ⇒ 30

what is −4(−5x+2)−3x−5= -30
Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
-4(-5x + 2) - 3x - 5 = -30
Step 2: Solve for x
Distribute -4: 20x - 8 - 3x - 5 = -30
Combine like terms: 17x - 13 = -30
Add 13 on both sides: 17x = -17
Divide both sides by 17: x = -1
Answer:
x = -1
Step-by-step explanation:
invere operation
−4(−5x+2)−3x−5= -30
20x - 8 -3x - 5 = -30
17x -13 = -30
17x = -17
x = -1
write the product of a number and 21 as an algebraic expression
Answer:
21n=
n-number and since its a number (n) and 21 you would put 21n
Answer:
[tex]\boxed {\tt 21n}[/tex]
Step-by-step explanation:
We want to write the product of a number and 21 as an algebraic expression. Let's define "a number" as the variable n.
We know that "product" means multiplication. The product of a number, n, and 21 is equal to multiplying n and 21.
[tex]n*21[/tex]
21 and n can be flipped due to the commutative property of multiplication.
[tex]21*n[/tex]
[tex]21n[/tex]
The product of a number and 21 is 21n.
Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to the ground? What does the integer 0 represent in this situation?
Answer:
He started climbing 9 feet up into the tree, so we can assume that the initial position is 9ft above the ground.
Then if he wants to get back into the ground, he must "descend" or climb down 9 ft again.
Then the integer is -9 (because he is climbing down now).
In this case, the 0 represents that he does not move.
So the integer 0 is related to: +0ft or -0ft
This means that he climbs up 0ft or down -0ft, which is the same as not moving at all.
After 8 points are added to each score in a sample, the mean is found to be M= 40. What was the value for the original mean
Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32

Regina, Phil and Joseph each wrote expressions to represent their hourly earnings for an after-school job where h represents the number of hours worked. Regina: 6.50h + 16 Phil: 3(2.5h + 5) Joseph: 7.50h + 10 How many hours will Regina and joseph have to work in order to make the same amount of money in one week? Show your work.
Answer:
Duration = 6 hours
Step-by-step explanation:
Given
[tex]Regina: 6.50h + 16[/tex]
[tex]Phil: 3(2.5h + 5)[/tex]
[tex]Joseph: 7.50h + 10[/tex]
Required
When will Ragina and Joseph earn equal amounts
To solve this:
[tex]Regina = Joseph[/tex] must be true
This gives:
[tex]6.50h + 16 = 7.50h + 10[/tex]
Collect Like Terms
[tex]7.50h - 6.50h = 16 - 10[/tex]
[tex]h = 6[/tex]
Hence, number of hours is 6

When using Newton's Method to find the root of a linear function f(x) = ax + b, a 70, how many iterations of the method are required to find the root at r = R?1 4 2 There is no fixed number. It depends on the intial guess xo.
Answer:
It depends on the initial guess Xo
Step-by-step explanation:
The number of iterations required to find the root at r = R depends on the initial guess Xo, this is because when using Newton's method for finding roots, you will need to pick an initial guess and this will be followed by an iterative process which would converge to a solution. The number of roots before the converging will take place depends on the initial guess Xo made
solve 2x^3+7x^2-2x-1=o
Answer:
[tex]x=\sqrt{3}-2\\x=-\sqrt{3}-2\\x=\frac{1}{2}[/tex]
Step-by-step explanation:
This is a hard one
We have to use the rational root theorem
[tex]2x^3+7x^2-2x-1[/tex] = 0
We have to find all the factors of a and d and put them in a fraction
[tex]a=2\\d=-1\\\frac{1}{1,2}[/tex]
We then plug them into the equation to see if any of them work
The equation isn't true when plugging 1, but is true when plugging in 1/2
factored form of 1/2 is (2x-1)
Then we divide the original equation by (2x-1) (you can use synthetic division or long division, it would be hard to type out the process for that) to get [tex]x^2+4x+1[/tex]
So now the equation is [tex](2x-1)(x^2+4x+1)[/tex]
Solve the second half of this equation using the quadratic formula to get
[tex]\sqrt{3}-2[/tex] and [tex]-\sqrt{3}-2[/tex]
We already know the solution for the first half of the equation (1/2)
So the final answers are:
[tex]x=\sqrt{3}-2, -\sqrt{3}-2, \frac{1}{2}[/tex]

In a sample fruit basket, there are 2 apples for every 3 oranges.
To make a large fruit basket with the same ratio using 20 apples, how many oranges are needed?
Help me please?!
Answer:
B 32
Step-by-step explanation:
30 oranges would be required to maintain the same ratio with 20 apples.
Solving linear equation.In the example fruit basket, there are 2 apples for every 3 oranges, based on the provided ratio.
We must establish a proportion in order to determine how many oranges are required to keep the same ratio with 20 apples.
Let "x" stand for the required quantity of oranges.
The ratio can be configured as follows:
20 apples/x oranges = 2 apples/3 oranges.
Cross-multiplication allows us to find the value of "x":
3(20) = 2x
2x = 60
x = 30
As a result, 30 oranges would be required to maintain the same ratio with 20 apples.
