Answer:
40% chance of success
Step-by-step explanation:
The possible integers chosen are 0, 1, 2, 3, and 4.
Since the numbers are randomly chosen and the numbers 2 and 3 represent a success, and the numbers 0, 1, and 4 represent a failure, and there are 5 possible outcomes, there is a 2/5 chance of success. Therefore, you have an estimated 40% chance of a success.

An online store holds a sale. Of the 500 customers who make purchases during the sale, 120 use a coupon. What percent of the customers do not use a coupon?
Answers
Total no of customers = 500
Used coupon = 120
Not used coupon = 500 - 120 = 380
We need to find the percentage of the customers do not use a coupon. It can be given by :
380/500×100
So, there are 76% of the customers that do not use a coupon.
500/100=5
Next, figure out what percentage of customers used a coupon
120/5= 24
Finally, find the percentage of customers who didn’t use a coupon
100-24=76%

when camping alone , mr adam uses all of the water in 12 days, then when mrs adams and mr adams camp together they use all of the water in storage in 8 days. if mrs adams camps alone in how many days will she use all of the water?
Answers
Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are:
Together: 1/8.Mr Adam: 1/12.Mrs Adams: 1/x.Hence:
[tex]\frac{1}{12} + \frac{1}{x} = \frac{1}{8}[/tex]
[tex]\frac{x + 12}{12x} = \frac{1}{8}[/tex]
[tex]12x = 8x + 96[/tex]
[tex]4x = 96[/tex]
[tex]x = \frac{96}{4}[/tex]
[tex]x = 24[/tex]
If Mrs Adams camps alone, she will use all the water in 24 hours.

1.7 x 10= 17 (moving one decimal point to the right)
1.7 x 100=170 (moving two decimal points to the right)
1.7 x 1000= 1700 (moving 3 decimal points to the right)
Reflect: The decimal changes depending on the number of zeros in each multiple of ten that it is multiplied by. If it is multiplied by 10 for instance, the decimal is moved one place to the right since there is one 0, if by 100 then it is moved two places to the right since there are 2 zeros, and if by 1000 then it is moved 3 places to the right for the 3 zeros.
If given in the following expression, find the value of
(x^3 + y^3):(x^3-y^3)
If (x^2+y^2)/(x^2 -y^2)= 17 /8
Answers
Step-by-step explanation:
Given that:
{(x²+y²)/(x²-y²)} = 17/8
On applying cross multiplication then
since, (a/b) = (c/d) ⇛a(d) = b(c)
Where, x = x²+y², b = x²-y², c = 17 and d = 8
So,
⇛17(x²-y²) = 8(x²+y²)
Multiply the number outside of the brackets with variables in the brackets on both LHS and RHS.
⇛17x²-17y² = 8x²+8y²
⇛17x²-17y² - 8x²-8y² = 0
⇛17x²- 8x² - 17y² - 8y² = 0
⇛9x² - 25y² = 0
⇛9x² = 25y²
⇛9/25 = y²/x²
⇛25/9 = x²/y²
⇛x/y = √(25/9)
⇛x/y = √{(5*5)/(3*3)}
⇛x/y = 5/3
Therefore, x:y = 5:3
Let x = 5a and y = 3a
Now, (x³+y³):(x³-y³)
= {(x³+y³)/(x³-y³)} = [{(x+y)(x²-xy+y²)}/{(x-y)(x²+x-y+y²)}]
= [{(5a)³ + (3a)³}/{(5a)³ - (3a)³}]
= [{(5*5*5*a*a*a) + (3*3*3*a*a*a)}/{(5*5*5*a*a*a) - (3*3*3*a*a*a)}]
= {(125a³ + 27a³)/(125a³ - 27a²)}
= {(152a³)/(98a³)}
= 152/98
Write the obtained fraction in lowest form by cancelling method.
= {(152÷2)/(98÷2)}
= 76/49
Therefore, , (x³+y³):(x³-y³) = 76/49
Answer: Hence, the required value of (x³+y³):(x³-y³) is 76/49.
Please let me know if you have any other questions.
Answer:
76:49 or 49:76
Step-by-step explanation:
The second relation gives an expression for y in terms of x:
[tex]\dfrac{x^2+y^2}{x^2-y^2}=\dfrac{17}{8}\\\\8x^2+8y^2=17x^2-17y^2\qquad\text{cross multiply}\\\\25y^2=9x^2\qquad\text{add $(17y^2-8x^2)$}\\\\5y=\pm3x\qquad\text{take the square root}\\\\y=\pm\dfrac{3}{5}x\qquad\text{divide by 5}[/tex]
Substituting into the expression we want the value of, we can factor out x^3 to get ...
[tex](x^3+y^3):(x^3-y^3)=(1\pm(3/5)^3):(1\mp(3/5)^3)=(125\pm27):(125\mp27)\\\\=152:98\text{ or }98:152=\boxed{76:49\text{ or }49:76}\m[/tex]

Warren wanted to save money to purchase a new car. He started by saving $1 on the first of January. On the first of February, he saved $4. On the first of March, he saved $16. So on the first day of each month, he wanted to save four times as much as he did on the first day of the previous month. If Warren continues his savings pattern, how much will he need to save on the first day of July?
On the first day of July he will need to save $ (your answer here)
.
Answers
Answer:
On the first day of July he will need to have saved $4098 for his new car.
Step-by-step explanation:
So we know that on March he save $16 and the amount he needs to save each month increases by 4 times the previous month’s amount.
We can conclude then for April he would need to have saved $64.
In May, if we repeat the pattern of multiplying the previous month’s savings by 4, Warren would have saved $256.
We will continue this pattern for June and July.
In July we will multiply $1024 (total saved in June) by 4 to find that in July, Warren will have needed to save $4098

Answer:
y = 14 x = 2
Step-by-step explanation:
what we know:
x + y = 16
x = 3y - 40
3y - 40 + y = 16
4y - 40 = 16
add 40 to both sides
4y = 56
y = 14
x = 3(14) - 40
x = 42 - 40
x = 2
A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. Find the volume of the resulting ring.
Answers
The volume of the resulting ring is (4/3)π(R³ - r³)
Volume
The volume of an object is the amount of space occupied by the object in three dimension.
The volume (V) of a sphere is given by:
V = (4/3)πr³
Where r is the radius of the sphere.
For the sphere with radius R, volume is:
V = (4/3)πR³
The hole with radius r, has a volume of:
V = (4/3)πr³
Hence volume of the ring = (4/3)πR³ - (4/3)πr³ = (4/3)π(R³ - r³)
The volume of the resulting ring is (4/3)π(R³ - r³)
