Number 2
Answers
TU = 2x
UB = 3x
TB = 20
2x+3x=20
Solve that equation, you should get:
5x=20
Then divide by 5 on each side to get x.
x = 4
Then you want to plug x into each equation!
TU = 2x, so 2 • 4 = 8.
TU = 8
UB = 3x, so 3 • 4 is 12.
UB = 12
Tara's website, verdantveggies.com, specializes in the sale of rare or unusual vegetable seeds. Tara sells packets of sweet-pepper seeds for $2.85 each and packets of hot-pepper seeds for $4.29 each. She also offers a 16-packet mixed-pepper assortment combining packets of both types of seeds at $3.30 per packet. How many packets of each type of seed are in the assortment?
Answers
Answer:
Let's define the variables:
S = # of sweet pepper seeds in the mix pack.
H = # of hot pepper seeds in the mix pack.
Let's suppose that $3.30 is the mean price of the seeds in the mix pack.
Then we have two equations:
S + H = 16.
(S*$2.85 + H*$4.29)/16 = $3.30
Now let's solve this system.
The first step is isolating one variable in one of the equations, i will isolate S in the first equation.
S = 16 - H.
Now we can replace this in the second equation, and solve it for H.
( (16 - H)*$2.85 + H*$4.29)/16 = $3.30
( (16 - H)*$2.85 + H*$4.29) = $3.30*16 = $52.80
$45.60 + H*$1.44 = $52.80
H*$1.44 = $52.80 - $45.60 = $7.20
H = $7.20/$1.44 = 5
Then in the mix pack there are 5 hot-pepper seeds.
And the other 11 must be sweet-pepper seeds
Algebraic equations are equations that contain unknown variables.
The number of packets of sweet-pepper seeds is 11 and the number of packets of hot-pepper seeds is 5.
Let's represent:is
The number of packets of sweet-pepper seeds = s
The number of packets of hot-pepper seeds = h
Based on this question, our system of equations are:
$2.85 x s + $4.29 x h = $3.30(16)
2.85s + 4.29h = 52.8...........Equation 1
s + h = 16...........Equation 2
s = 16 - h
We substitute 16 - h for s in Equation 1
2.85(16 - h) + 4.29h = 52.8
45.6 -2.85h + 4.29h = 52.8
Subtract 45.6 from both sides
45.6 - 45.6 -2.85h + 4.29h = 52.8 - 45.6
1.44h = 7.2
h = 5
There are 5 hot-pepper seeds in the assortment.
Solving for the number of sweet-pepper seeds.
s = 16 - h
s = 16 - 5
s = 11
There are 11 sweet-pepper seeds in the assortment.
Therefore, the number of packets of sweet-pepper seeds is 11 and the number of packets of hot-pepper seeds is 5.

Answer:
[tex]P(X = 5) = 0.166[/tex]
Step-by-step explanation:
Given
[tex]Mean = 4.3[/tex]
[tex]x = 5[/tex]
Required
Determine the probability that the order is 5
This question can be answered using Poisson distribution.
[tex]P(X = x) = \frac{\alpha ^x e^{-\alpha}}{x!}[/tex]
Where
[tex]\alpha[/tex] is used to represent the mean
and
[tex]\alpha = 4.3[/tex]
[tex]x = 5[/tex]
[tex]e = 2.71828[/tex] ---- Euler's constant
So, we have:
[tex]P(X = x) = \frac{\alpha ^x e^{-\alpha}}{x!}[/tex]
[tex]P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5!}[/tex]
[tex]P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5* 4 * 3 * 2 *1}[/tex]
[tex]P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{120}[/tex]
[tex]P(X = 5) = \frac{1470.08443 * 0.01356859825}{120}[/tex]
[tex]P(X = 5) = \frac{19.9469850243}{120}[/tex]
[tex]P(X = 5) = 0.1662248752[/tex]
[tex]P(X = 5) = 0.166[/tex] Approximated

So how you would solve this word problem you would have to first see what your starting with, in the begging it mentioned that he gets paid [$14.15 and hour] and he worked for 40 hours, (multiple it) you get $566.0)
Then it says to see answer how much Jake makes in 58 hours, (now remember it mentioned how much he makes in an hour) so you just had to multiply 14.15 x 58= 820.70

an inspector tested the first 125 radios that came off the production line today and found only 60% acceptable. After the inspector tested 25 more radios, the overall percentage of acceptable radios rose to 62%. The number of these 25 radios that were rejected is???
Answers
Answer: 7 radios
Step-by-step explanation:
The following can be deduced from the question:
Number of radios tested = 125 radios
Percentage acceptable = 60%
Numbers acceptable:
= 60% × 125
= 0.6 × 125
= 75 radios
Numbers rejected = 125 - 75 = 50 radio
We are further told that the inspector tested 25 more radios, this will be:
Number of radios tested
= 125 + 25 = 150 radios
Percentage acceptable = 62%
Numbers acceptable
= 62% × 150
= 0.62 × 150
= 93 radios
Numbers rejected= 150 - 93 = 57 radios
The number of these 25 radios that were rejected will be:
= 57 - 50
= 7 radios

Olga has $40 in her wallet. She has one more $5 bill than $10 bills, and two more $1 bills than $5 bills. If Olga has only three types of bills, how many bills of each denomination does she have?
Answers
Answer:
Number of $10 bills = 2
Number of $5 bills = 3
Number of $1 bills = 5
Step-by-step explanation:
Given:
Total amount = $40
Number of $10 bills = x
Number of $5 bills = x + 1
Number of $1 bills = x + 1 + 2 = x + 3
Find:
Number of each bills
Computation:
10(x) + 5(x+1) + 1(x+3) = 40
10x + 5x + 5 + x + 3 = 40
16x = 32
x = 2
Number of $10 bills = x = 2
Number of $5 bills = x + 1 = 3
Number of $1 bills = x + 3 = 5
Answer:
# of $10 bills = 2
# of $5 bills = 3
# of $1 bills = 5

Exercise 18.14. Toy defects. Workers at a factory produce a toy with a defect about once every 4 hours on average. Each toy costs the factory approximately $7 in labor and supplies. a. What is the expected number of toys with defects at the end of a 40-hour work week
Answers
Answer: $70
Step-by-step explanation:
Given that:
Toy with defect is produced once every 4 hours
Cost of labor and supplies incurred for producing a defective toy = $7
Number of defective toys that is expected to be produced in a 40 hour work week :
Number of hours / average hour for producing 1 defective toy
= 40/ 4
= 10 defective toys
Cost incurred for producing 10 defective toys :
($7 * 10) = $70
