Answer:
trust me on this answer. It is D, a = 1, b = 2, c = 3
Step-by-step explanation:
Okay, so the problem is 5/8 divided by 3/8.
So, you find the reciprocal, which then is 5/8 x 8/3
Since there is an 8 is both the first denominator and the second numerator, you cross them out, which leaves you 5/3
So, 5 can go into 3, only 1 time.
5/3 = 3/3 + 2/3
So, 3/3 + 2/3 = 1 2/3
Therefore, D is the answer of choice.

Z+(z-6)-2=-10
How donI solve this?
Answer:
z = -1
Step-by-step explanation:
Simplifying
z + (z + -6) + -2 = -10
Reorder the terms:
z + (-6 + z) + -2 = -10
Remove parenthesis around (-6 + z)
z + -6 + z + -2 = -10
Reorder the terms:
-6 + -2 + z + z = -10
Combine like terms: -6 + -2 = -8
-8 + z + z = -10
Combine like terms: z + z = 2z
-8 + 2z = -10
Solving
-8 + 2z = -10
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 2z = -10 + 8
Combine like terms: -8 + 8 = 0
0 + 2z = -10 + 8
2z = -10 + 8
Combine like terms: -10 + 8 = -2
2z = -2
Divide each side by '2'.
z = -1
Simplifying
z = -1
Answer:
z= -1

What is the Calculate
Answer:
From the given figure, we can see that
∠LON = ∠LOM + ∠MON
replacing the variables with the given values
77 = 9x + 44 + 6x + 3
77 = 15x + 47
15x = 30
x = 2
Finding ∠MON:
we are given that ∠MON = 6x +3
now that we know the values of x,
∠MON = 6(2) + 3
∠MON = 12 + 3
∠MON = 15°
Jacob is a construction worker who earns a yearly income given by the expression 2000x + 3000, where x is the number of hours he works each week. Carlos works with Jacob and earns a yearly income given by the expression 3800x – 40000. A manager predicts that if Carlos and Jacob each work 35 hours, they will earn the same amount of money.
PART A:The number of hours that makes the equation true is
Options: 24, 27, 29,31,34
PART B:Round your answer to the nearest whole number. The manager's prediction is
Options: equal to, less than, greater than
the actual number of hours that Carlos and Jacob need to work to earn the same amount of money.
Answer:
[tex]x = 24[/tex]
24 is less than 35
Step-by-step explanation:
Given
Jacob: 2000x + 3000
Carlos: 3800x - 40000
Solving (a):
To solve (a), we need to equate both expressions;
[tex]3800x - 40000 = 2000x + 3000[/tex]
Collect Like Terms
[tex]3800x - 2000x = 40000 + 3000[/tex]
[tex]1800x = 43000[/tex]
Solve for x
[tex]x = 43000/1800[/tex]
[tex]x = 24[/tex] --- Approximated
Solving (b);
The manager's prediction is 35 hours.
And the actual hours is 24.
By comparison;
24 is less than 35

A sample of size 100 is selected from a population with p = .40.
a. What is the expected value of p(bar)?
b. What is the standard error of p(bar)?
c. Show the sampling distribution of p(bar)?
d. What does the sampling distribution of p show?
Answer:
(a) 0.40
(b) 0.049
(c) [tex]\bar p\sim N(0.40,0.049^{2})[/tex]
(d) Explained below
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
[tex]E(\bar p)=p[/tex]
The standard deviation of this sampling distribution of sample proportion is:
[tex]SE(\bar p)=\sqrt{\frac{p(1-p)}{n}}[/tex]
Given:
n = 100
p = 0.40
As n = 100 > 30 the Central limit theorem is applicable.
(a)
Compute the expected value of [tex]\bar p[/tex] as follows:
[tex]E(\bar p)=p=0.40[/tex]
The expected value of [tex]\bar p[/tex] is 0.40.
(b)
Compute the standard error of [tex]\bar p[/tex] as follows:
[tex]SE(\bar p)=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.40(1-0.40)}{100}}=0.049[/tex]
The standard error of [tex]\bar p[/tex] is 0.049.
(c)
The sampling distribution of [tex]\bar p[/tex] is:
[tex]\bar p\sim N(0.40,0.049^{2})[/tex]
(d)
The sampling distribution of p show that as the sample size is increasing the distribution is approximated by the normal distribution.
The midpoint of AB is M(3,3). If the coordinates of A are (2, -1), what are the
coordinates of B?
Answer:
(4, 7)
Step-by-step explanation:
Given that:
Midpoint of AB = M(3, 3)
Coordinate of A = (2, - 1)
Let coordinates of B = (x, y)
Recall :
Midpoint of AB = [(Ax + Bx) / 2, (Ay + By) / 2]
Mx = (Ax + Bx) / 2
My = (Ay + By) / 2
Mx = 3
Mx = (Ax + Bx) / 2
3 = (2 + x) / 2
2*3 = 2 + x
6 = 2 + x
6 - 2 = x
4 = x
My = 3
My = (Ay + By) / 2
3 = (-1 + y) / 2
2*3 = - 1 + y
6 = - 1 + y
6 + 1 = y
7 = y
Hence,
B = (4, 7)

MD Model with Mathematics A comic store sells two rare
comic books for $1,824. The price of one comic book is
11 times as much as the price of the other.
• 'Write an equation to model the price of the less expensive
comic book. Then find the price.
• Write an equation to model the price of the more expensive
comic book. Then find the price.
Let the cost of the less expensive comic book be x .
Then :-
[tex]1284 - 11x = x[/tex]
Using this equation , we can find the cost of the less expensive comic book .
Price of the less expensive book :-
[tex]1284 - 11x = x[/tex]
[tex]11x + x = 1284[/tex]
[tex]12x = 1284[/tex]
[tex]x = \frac{1284}{12} [/tex]
[tex]x = 107[/tex]
Cost of the less expensive book is 107 .
Therefore , the epice of the less expensive book = $ 107 .
Solution (b) :-Cost of the more expensive book = 11x
Which means :-
[tex]1284 - x = 11x[/tex]
[tex]11x + x = 1284[/tex]
[tex]12x = 1284[/tex]
[tex]x = 107[/tex]
[tex]11x = 11 \times 107[/tex]
[tex] = 1177[/tex]
Therefore , the price of the more expensive book = $ 1177 .
Perfect Purple Water The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." lada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water. . Which person will get a color mixture that is the same shade as Perfect Purple Water? Explain or show your reasoning.
Analysing the question:
We are given that the ratio between the blue and red color is 8 : 3
as long as the volumes of the colours added simplify to 8 : 3 , the color will be Perfect Purple
Lada's Solution:
Lada mixed 24 mL of blue water with 9 mL of red water
we will try to simplify this ratio:
24:9 = 24 / 9
8 / 3
8 : 3
Hence, the ratio of the colours in Lada's mixture is correct. So, Lada will get perfect purple water
Andre's Solution:
Andre mixed 16mL of Blue water with 9 mL of red water
we will try to simplify this ratio:
16 : 9 = 16 / 9
THIS RATIO CANNOT BE SIMPLIFIED
Hence, the ratio of blue and red color in Andre's mixture is 16 : 9
but the ratio for a perfect purple color is 8 : 3
Since the ratio in Andre's mixture is incorrect, she will NOT get the perfect purple colour
Answer:
Lada will get a color mixture that is the same shade as Perfect Purple Water.
Step-by-step explanation:
Proportions
The mix for Perfect Purple Water contains 8 ml of blue water with 3 ml of red water.
The exact proportion of both ingredients is, blue to red:
[tex]\displaystyle \frac{8}{3}[/tex]
Lada mixes 24 ml of blue water with 9 ml of red water. The proportion is:
[tex]\displaystyle \frac{24}{9}[/tex]
Simplifying by 3:
[tex]\displaystyle \frac{8}{3}[/tex]
The proportion obtained by Lada is the same shade as Perfect Purple Water.
Andre mixes 16 ml of blue water with 9 ml of red water, his proportion is:
[tex]\displaystyle \frac{16}{9}[/tex]
This fraction cannot be reduced and its result is not exactly the same as the perfect required proportion.
Thus, Lada will get a color mixture that is the same shade as Perfect Purple Water.

Step-by-step explanation:
Ida purchases a variety bag of taffy to share with her friends. The bag contains pieces with the flavors of blueberry, strawberry, and lemon. Ida wants to know how many pieces of each flavor are in the bag. She pulls 25 pieces from the bag at random and records their flavor. Her results are shown in the following table.
A: Given the results of Ida’s experiment, what is the probability that the next piece of taffy she pulls from the bag will be lemon-flavored?
B: If the bag contains a total of 200 pieces of taffy, how many of the pieces are likely lemon-flavored?
Select one answer for question A and one answer for question B.
(Table Below)
Flavor Count
blueberry 8
strawberry 5
lemon 12
Possible Answers:
A: 8/25
A: 12/25
A: 13/25
A: 3/5
B: 96 pieces
B: 40 pieces
B: 64 pieces
B: 100 pieces
Answer:
A. 12/25
B. 96 pieces
Step-by-step explanation:
A. For this, Ida got 12/25 lemon taffies, therefore the probability is the same.
B. The ratio of lemon to other taffies is 12/25. This means that for every 25 pieces of taffy, 12 of them are lemmon. If you multiply the numerator and denominator by 8, you get 96/200, which says that out of 200 pieces, 96 should be candy.
