On this necklace the ratio of black beads to white beads is 1:4
How many more black beads do you need to
add to make the ratio of black to white 4:1 ?
Answer:
16
Step-by-step explanation:
This is because the ratio of black to white can be set up as 1/4, for every one black bead there is 4 white so what is 1/4x that equals 4? simple, x=16 because 16/4 equals to 4 so it would be 4 black beads to 1 white bead.
A woman had $200. She went to a meatshop,
a bookstore and a drugstore. She spent four
times as much money at the meatshop as she
did at the drugstore. She spent $15 less at the
bookstore than at the drugstore. She then had
$5 left.
(a) Using $x to represent the amount she spent
at the drugstore, express in algebraic terms
(i) the amount she spent at the meatshop
(ii) the amount she spent at the bookshop
(b) Obtain an equation for the total amount
of money spent and hence calculate the
amount she spent at the drugstore.

Answer:
5500 ml or 5.5 liters
Step-by-step explanation:
First, we should note that there are 1000 milliliters in 1 liter of liquid.
So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.
To find the total amount, we find the sum of all the milliliters:
1500 + 750 + 2250 + 1000 = 5500 ml
Again, we know that there are 1000 milliliters in 1 liter of liquid, so:
[tex]\frac{5500}{1000}[/tex] = 5.5 liters

Answer:
the volume of the rectangular prism is 448.5 in^3
Step-by-step explanation:
The computation of the volume of the rectangular prism is shown below:
As we know that
The volume of the rectangular prism is
= 7.8 × 11.5 × 5
= 448.5 in^3
It is basically multiplied with the height, width and the length
Hence, the volume of the rectangular prism is 448.5 in^3

Answer:
y = 3x -6
Step-by-step explanation:
The three turning points of the terms divide the graph into 4 pieces. We can consider what functions apply in each piece.
x < -2
All terms are negated:
y = (3 -x) -(x +2) -(5 -x) = -x -4
-2 < x < 3
The first and last terms are negated:
y = (3 -x) +(x +2) +(x -5) = x
3 < x < 5
The last term is negated:
y = (x -3) +(x +2) +(x -5) = 3x -6
5 < x
No terms are negated:
y = (x -3) + (x +2) -(x -5) = x +4
_____
In the region of interest, the equation simplifies to y = 3x -6.

Mariel says that a jewelry box that is 3 inches high, 4 1/2 inches wide, and 5 inches long has a volume of 67 1/2 inches. Katie says that answer is not quite correct. What is the error in Mariel's answer?
Answer: inside width, length and heights may be smaller
Step-by-step explanation. Walls of box have certain thickness, assume 0.1 inches. Then inner measures would be 2.8 in, 4.3 in and 4.8 in. You need to reduce thickness of wall from both sides.

If θ is an angle in standard position whose terminal side lies in quadrant III and sin θ=-√3/2, find the exact value of the tan θ
Answer:
C) √3
tanθ = √3
Step-by-step explanation:
Step:-1
Given that θ be an angle in standard position whose terminal side
Given that the angle
sinθ = [tex]\frac{-\sqrt{3} }{2}[/tex]
Given that the Opposite side AB = [tex]\sqrt{3}[/tex]
Hypotensue AC = 2
Step(ii):-
By using Pythagoras theorem
AC² = AB² +BC²
BC² = AC² - AB²
BC² = 4 - (√3)²
= 4-3
BC = 1
Adjacent side(BC) = 1
Step(iiI):-
Given that 'θ' lies in the third quadrant so tanθ is positive
tanθ = [tex]\frac{AB}{BC} = \frac{\sqrt{3} }{1}[/tex]

3. $595 refrigerator; 22% discount.
Show the work
Answer:
Discount: $130.90
Total cost after discount: $464.10
Step-by-step explanation:
Since I don't know what the actual question is, I will solve for the discount:
595 × 22%
Convert percentage into decimal
595 × 0.22
130.9
Discount is 130.9
Now I'll solve for how much that will take off from the original price:
595 - 130.9
464.1

Many manufacturers have quality control programs that include inspection of incoming materials for defects. Suppose a computer manufacturer receives computer boards in lots of five. Two boards are selected from each lot for inspection. We can represent possible outcomes of the selection process by pairs. For example, the pair
(1, 2) represents the selection of boards 1 and 2 for inspection.
(a) List the ten different possible outcomes.
(b) Suppose that boards 1 and 2 are the only detective boards in a lot of five. Two boards are to be chosen at random. Define X to be the # of defective boards observed among those inspected. Find the pmf.
Answer:
a) S = {(1,2), (1,3), (1,4), (1,5), (2,3), (2,4), (2,5), (3,4), (3,5), (4,5)}
b) p(x) = 0.3 if x = 0
= 0.6 if x = 1
= 0.1 if x = 2
= 0 otherwise
Step-by-step explanation:
Given - Many manufacturers have quality control programs that include inspection of incoming materials for defects. Suppose a computer manufacturer receives computer boards in lots of five. Two boards are selected from each lot for inspection. We can represent possible outcomes of the selection process by pairs. For example, the pair (1, 2) represents the selection of boards 1 and 2 for inspection.
To find - (a) List the ten different possible outcomes.
(b) Suppose that boards 1 and 2 are the only detective boards in a lot of five. Two boards are to be chosen at random. Define X to be the # of defective boards observed among those inspected. Find the pmf.
Proof -
(a)
Given that there are 5 computer boards
Let,
The Boards are 1, 2, 3, ,4 and 5.
Now,
Total Number of possible ways of selecting 2 boards out of 5 by inspection = ⁵C₂ = [tex]\frac{51}{2! (5-2)!}[/tex] = [tex]\frac{5!}{2! 3!}[/tex] = [tex]\frac{5.4.3!}{2! 3!}[/tex] = [tex]\frac{5.4}{2.1}[/tex] = 10
And the choices be
Choice I -
Boards 1 and Board 2
Choice II -
Board 1 and Board 3
Choice III -
Board 1 and Board 4
Choice IV -
Board 1 and Board 5
Choice V -
Board 2 and Board 3
Choice VI -
Board 2 and Board 4
Choice VII -
Board 2 and Board 5
Choice VIII -
Board 3 and Board 4
Choice IX -
Board 3 and Board 5
Choice X -
Board 4 and Board 5
And
These outcomes becomes
S = {(1,2), (1,3), (1,4), (1,5), (2,3), (2,4), (2,5), (3,4), (3,5), (4,5)}
(b)
Given that, X be the number of defective boards
And there are only two defective boards (Board 1 and Board 2) in the lot
Therefore,
X can be 0, 1, and 2.
Now,
If X = 0
⇒ There is no defective boards
⇒ Possible outcomes be - { (3,4), (3,5), (4,5) }
So,
P(X=0) = [tex]\frac{3}{10}[/tex] = 0.3
Now,
If X = 1
⇒ There is one defective board
⇒ Possible outcomes be - { (1,3), (1,4), (1,5), (2,3), (2,4), (2,5) }
So,
P(X=1) = [tex]\frac{6}{10}[/tex] = 0.6
Now,
If X = 2
⇒ There is two defective boards
⇒ Possible outcomes be - { (1,2) }
So,
P(X=2) = [tex]\frac{1}{10}[/tex] = 0.1
And
P(x) = 0 if x ≠ 0, 1, 2
SO, The pmf be
p(x) = 0.3 if x = 0
= 0.6 if x = 1
= 0.1 if x = 2
= 0 otherwise
