In 2010, Joe bought 200 shares in the Nikon corporation for $22.07 per share. In 2016 he sold the shares for $15.11each.
a. What was Joe's capital loss?
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
Answer: a. $1392
b. 31.5%
Step-by-step explanation:
a. What was Joe's capital loss?
Cost price = $22.07 × 200 = $4414
Selling price = $15.11 × 200 = $3022
Capital loss = $3022 - $4414
= -$1392
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
= Capital loss/Cost price × 100
= 1392/4414 × 100
= 31.5%
Answer:
a. $1392
b. 31.5%
Step-by-step explanation:
a. What was Joe's capital loss?
Cost price = $22.07 × 200 = $4414
Selling price = $15.11 × 200 = $3022
Capital loss = $3022 - $4414
= -$1392
b. Express Joe's capital loss as a percent, rounded to the nearest percent.
= Capital loss/Cost price × 100
= 1392/4414 × 100
= 31.5%

Explain how you would solve the equation -7 + x = 12 using the properties of equality. (Site 1)
Given problem:
Solve using the property of equality;
-7 + x = 12
The properties of equality are;
Addition. Definition. If x = y, then x + c = y + c. ...
Subtraction. Definition. If x = y, then x – c = y – c. ...
Multiplication. Definition. If x = y, then xc = yc. ...
Division. Definition. If x = y and c is not equal to 0, then x / c = y / c
Now;
- 7 + x = 12;
base on the properties of equality, to eliminate -7, add +7 to both sides;
-7 + 7 + x = 12 + 7
x = 19
Based on the properties of equality, the solution is 19

-3x-9=27x-6(5x-9) plz help
Answer:
No Solution
Step-by-step explanation:
Use the distributive property, to take out the contents from the parentheses
-6 * 5x = -30x
-6 * -9 = 54
-30x + 54
27x -30x + 54
Combine the terms that have the same variable
27x + -30x = -3x
-3x + 54
-3x - 9 = -3x + 54
Combine terms that have the same variable
-3x + 3x = 0
-9 = 54
-9 does not equal 54, therefore there is no solution

Items are inspected for flaws by two quality inspectors. Both inspectors inspect every item and the probability that an item has a flaw is 0.1. If a flaw is present,it will be detected by the first inspector with probability 0.92, and by the second inspector with probability 0.7. If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 and by the second inspector with probability 0.8. Assume the inspectors function independently.
(a) If an item has a flaw, what is the probability that it will be found by at least one of the two inspectors?
(b) If an item is passed by the first inspector, what is the probability that it actually has a flaw?
(c) What is the probability that the two inspectors draw different conclusions on the same item?
(d) If an item is passed by both inspectors, what is the probability that it actually has a flaw?
Answer:
a)0.976
b)0.00926
c)0.2402
d)0.35
Step-by-step explanation:
Let [tex]X_i[/tex] be an item passed by inspector i
Let Y be the event that there is a fault in an item
The probability that an item has a flaw is 0.1 i.e. P(Y)=0.1
If a flaw is present ,it will be detected by the first inspector with probability 0.92 i.e.[tex]P(\bar{X_1}|Y)=0.92[/tex]
So, [tex]P(X_1|Y)=1-0.92=0.08[/tex]
If a flaw is present ,it will be detected by the second inspector with probability 0.7 i.e.[tex]P(\bar{X_2}|Y)=0.7[/tex]
So,[tex]P(X_2|Y)=1-0.7=0.3[/tex]
If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 i.e. [tex]P(X_1|\bar{Y}) = 0.95[/tex]
So, [tex]P(\bar{X_1}|\bar{Y}) = 1-0.95=0.05[/tex]
If an item does not have a flaw, it will be passed by the second inspector with probability 0.8 i.e. [tex]P(X_2|\bar{Y}) = 0.8[/tex]
So, [tex]P(\bar{X_2}|\bar{Y}) = 1-0.8=0.2[/tex]
a)P(found by atleast one inspector | It has flaw )=1-P(found by none inspector | It has flow )
P(found by atleast one inspector | It has flaw )=[tex]1-P(X_1|Y) P(X_2|Y)[/tex]
P(found by atleast one inspector | It has flaw )=[tex]1-0.08 \times 0.3[/tex]
P(found by atleast one inspector | It has flaw )=0.976
Hence the probability that it will be found by at least one of the two inspectors if it has flaw is 0.976
b)[tex]P(Y|X_1)=\frac{P(X_1|Y) P(Y)}{P(X_1|Y) P(Y)+P(X_1|\bar{Y}) P(\bar{Y})}[/tex]
[tex]P(Y|X_1)=\frac{0.08 \times 0.1}{0.08 \times 0.1+0.95 \times 0.9}=0.00926[/tex]
C)P( two inspectors draw different conclusions on the same item)=[tex]P(X_1 \cap \bar{X_2} \cap Y)+P(\bar{X_1} \cap X_2 \cap Y)+P(X_1 \cap \bar{X_2} \cap \bar{Y})+P(\bar{X_1} \cap X_2 \cap \bar{Y})[/tex]
P( two inspectors draw different conclusions on the same item)=0.2402
D)
[tex]P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2)}\\P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2 \cap Y)+P(X_1 \cap X_2 \cap \bar{Y})}\\P(Y|(X_1 \cap X_2))=0.35[/tex]

San is using an industrial kitchen to bake several batches of his famous chocolate chip granola bars. He needs to weigh out 78 ounces of chocolate chips, plus or minus 2.5 ounces. Given the equation, |c-78|=2.5, find the minimum and maximum amount of c of chocolate chips that he can weigh out. Explain all steps and solve.
Step-by-step explanation:
given that San weighs out 78 ounces
given that the margin is 2.5 ounces.
and also given that the formula is
|c-78|=2.5
maximum
the maximum ounces is= 78+2.5
the maximum ounces is= 80.5 ounces
minimum
the maximum ounces is= 78-2.5
the maximum ounces is= 76.5 ounces

Solve the equation x^2 = 10.
Answer: [tex]\sqrt{10\\[/tex]
Step-by-step explanation:
To solve for x you would have to take the square root of both side.
Answer:
x = about 3.16Step-by-step explanation:
In algebra, the goal is to isolate the variable, so its value can be determined.
x^2 = 10
square root both sides
x = [tex]\sqrt{10}[/tex] or about 3.16A square garden has an area of 100ft^2. What is the perimeter of the garden?
Given:
The area of a square garden = 100 sq. ft
To find:
The perimeter of the garden.
Solution:
Let the side of the square garden be a.
Area of a square = [tex]a^2[/tex]
So, [tex]a^2=100[/tex].
Taking square root on both sides.
[tex]a=\pm \sqrt{100}[/tex]
[tex]a=\pm 10[/tex]
Length of side cannot be negative. So, a=10. It means, side length of the garden is 10 ft.
Perimeter of square = 4a.
Perimeter of square garden is
[tex]4(10)=40[/tex]
Therefore, the perimeter of the square garden is 40 ft.

The cost of the hiking trip is 2/3 of the cost of last years trip this year trip cost $32 write and solve an equation to find the cost of last years trip
Answer:
(32/2)*3=48
Step-by-step explanation:
In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.
Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.
If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
