An Integrated Circuit (IC) chip is declared as "good" if it passes the quality acceptance test. Otherwise, the chip is declared as "bad". A mechanical machine produces two IC chips in pairs. Tests show that the first chip is good with probability 3/5. When the first chip is good, the probability that the second chip is good is 4/5. When the first chip is bad, the probability that the second chip is good is 2/5. a) What is the probability that both chips are good? b) What is the probability that both chips are bad? c) What is the probability that exactly one chip is good?
Answer:
a) The probability of both chips being good = 0.48
b) The probability of both chips being bad = 0.24
c) The probability of one chip being good = 0.60
Step-by-step explanation:
Probability of first chip being good = 3/5 = 0.60
Probability of second chip being good = 4/5 = 0.80
Probability of first chip being bad = 0.40 or 2/5 (1 - 3/5)
Probability of second chip being good if the first is bad = 2/5 = 0.4
Therefore, the probability of it being bad = 0.60 (1 - 0.40)
For both chips to be good, the probability = 0.60 * 0.80 = 0.48
For both chips to be bad, the probability = 0.60 * 0.40 = 0.24

A recipe for homemade modeling clay includes 1/3 cup of salt for every cup of water. If there are 6 cups of salt, how many gallons of water are needed?
Answer:
Step-by-step explanation:
If for a cup of water, 1/3 cup of salt is needed, to get the number of gallons of water needed for 6 cups of salt, we will use the following equation;
1/3 cup of salts = 1 cup of water
6 cups of salt = x cups of water
cross multiply
1/3 * x= 6*1
x/3 = 6
multiply both sides by 3
x/3 * 3 = 6*3
x = 18
Hence 6 cups of salt will need 18 gallons of water
What is the scale factor of ABC to DEF?
A.6
B.8
C.1/8
D.1/6
Answer:
eight
Step-by-step explanation:
The scale factor of ΔABC to ΔDEF is 8. Hence, option B is the right choice.
What is a scale factor?The scale factor between two figures (any dimensions) is the scale to which the original figure (preimage) is multiplied to make the transformed figure (image).
How do we solve the given question?In ΔABC and ΔDEF,
AB/DE = BC/EF = CA/FD (Corresponding sides of triangle are in ratio)
∴ ΔABC ~ ΔDEF (SSS axiom)
The scale factor = A side of ΔDEF/Corresponding side of ΔABC = DE/AB = 48/6 = 8.
∴ The scale factor of ΔABC to ΔDEF is 8. Hence, option B is the right choice.

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the monthly demand for widgets. WidgCo's marketing department determines that p and x are related by the following demand equation: p(x) = 211 − 5x. The cost of producing x widgets is given by C(x) = 1,401 + 16x. Construct the revenue function, R(x). Find the production level that will result in the maximum revenue. Find the maximum monthly revenue. Enter your answer to part c in the box below. Round your answer to the nearest cent.
Answer:
The answer to this question can be defined as follows:
i) [tex]\bold{p(x)= -5x^2+ 217x- 1,401} \\[/tex]
ii) x=22 units
iii) Maximum profit: 953.45
Step-by-step explanation:
Given value:
p(x) = 211 − 5x \\
C(x) = 1,401 + 16x
The formula for calculating the profit function value:
[tex]\to \bold{P(x)= xp(x) - C(x)}[/tex]
[tex]= x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\[/tex]
The formula for calculating the value for maximum profit:
[tex]p'(x) = - 10x + 217 =0[/tex]
[tex]217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7[/tex]
So, the production level is 22 units
Maximum profit:
[tex]\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\[/tex]
[tex]=-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45[/tex]
The maximum monthly revenue of WidgCo is; $489
We are given;price function; p(x) = 211 - 5x
Cost function; C(x) = 1401 + 16x
We know that revenue would be gotten by the formula;Revenue = number of units sold × price per unit
Thus;
R(x) = x(211 - 5x)
Expanding this gives;
R(x) = 211x - 5x²
Maximum revenue will be the revenue for the number of widgets when R'(x) = 0. Thus;R'(x) = 211 - 10x
At R'(x) = 0, we have;
211 - 10x = 0
x = 211/10
x = 21.1
x ≈ 21 widgets
Thus;Maximum Revenue is;
R(20) = 195(21) - 1401 - 5(21)²
R(20) = $489

Suppose a number is chosen at random from the set {0,1,2,3,...,497}.
What is the probability that the number is a perfect cube?
===========================================================
Explanation:
Cube values in the set {0,1,2,3,...} until we reach a result larger than 497
0^3 = 01^3 = 12^3 = 83^3 = 274^3 = 645^3 = 1256^3 = 2167^3 = 3438^3 = 512We stop here because 512 is larger than 497.
Or you could note that [tex]\sqrt[3]{497} = 497^{1/3} \approx 7.921[/tex] helping us see that we stop at 8.
The list of nonnegative perfect cubes less than 497 is {0,1,8,27,64,125,216,343}
There are 8 items in that set out of 498 items in the set {0,1,2,3,...,497}
So the probability of getting a perfect cube is 8/498 = 4/249
you deposit 2000 each year into an account earning 3% interest compounded annually. How much will you have in the account in 15 years?
Answer:
It should be $2,900
Step-by-step explanation:
First you convert the percentage to decimal form out of 100
3%/100 = 0.03
A = P(1 + rt)
A = 2000(1 + 0.03 x 15)
Which you should get $2,900 or $2,900.00 (which is pretty much the same thing)

Answer: chart b
Step-by-step explanation:
2 is only a product of the outcomes 1/18 times
3 is only a product of the outcomes 1/18 times
4 is only a product of the outcomes 1/12 times
5 is only a product of the outcomes 1/18 times
6 is only a product of the outcomes 1/9 times
and so on
The chart that shows the probability distribution for the sum of the two numbers is chart B.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
When two dice are rolled, 36 equally likely outcomes are possible
The sum of the 36 outcomes are as follows: 2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12
The number of the sums are as follows:
n(2) = 1
n(3) = 2
n(4) = 3
n(5) = 4
n(6) = 5
n(7) = 6
n(8) = 5
n(9) = 4
n(10) = 3
n(11) = 2
n(12) = 1
The probability of the sums are given as follows:
p(2) = 1/36
p(3) = 2/36 = 1/18
p(4) = 3/36 = 1/12
p(5) = 4/36 = 1/9
p(6) = 5/36
p(7) = 6/36 = 1/6
p(8) = 5/36
p(9) = 4/36 = 1/9
p(10) = 3/36 = 1/12
p(11) = 2/36 = 1/18
p(12) = 1/36
Therefore, the chart that shows the probability distribution for the sum of the two numbers is chart B.
