A manufacturer of women’s blouses has noticed that 80% of their blouses have no flaws, 15% have one flaw, and 5% have two flaws. If you buy a new blouse from this manufacturer, the expected number of flaws will be:_________

a. 0.15
b. 0.20
c. 0.80
d. 1.00
e. none of the above

Answers

Answer:

b

Step-by-step explanation:

80% +15% +5%=100

15/100= 0.15

5/100= 0.05

therfore

0.15 + 0.05 = number of flaws

=0.20

Based on the flaws that the manufacturer notices, we can infer that the expected number of flaws will be 0.25 which is e. none of the above.

The expected number of flaws is a weighted average of the percentages that have flaws:

=∑ (Percentage of flaws x Number of flaws)

The expected number of flaws is therefore:

= (80% x 0) + (15% x 1) + (5% x 2)

= 15% + 10%

= 0.25

In conclusion, you would expected the number of flaws to be 0.25.

solve his problem for X and Y​

Answers

Answer:

y = 5, 3; x = 171, 155

Step-by-step explanation:

8y - 15 = y^2

y^2-8y+15=0

y^2-3y-5y+15=0

y(y-3)-5(y-3)=0

(y-5)(y-3)=0

y can be 5 or 3.

x = 180 - (8y - 15)

x = 180 - (8(3)-15)

x = 180 - 9

x = 171

OR

x = 180 - (8(5) - 15)

x = 180 - 25

x = 155

it take her to jog around the track 42 times? Give your answer in hours and
minutes, to the nearest minute.
40 m
130 m

Answers

Answer:

1 hour 29 minutes and 29 seconds

Step-by-step explanation:

We need to find the circumference of the two semicircles of the track (which forms a full circle of radius 40m):

pi×40×2 = 80pi

The total length of the track to be travelled would be:

(80pi+130+130) × 42 = (80pi+260) ×42

                       = 21 476m (Rounded to 5 s.f.)

80m/20s

1s = 80÷20

   = 4m

For every 1 second, Kat travels 4m.

Total Time taken:

21 476÷4 = 5369 seconds

               = 1 hour 29 minutes and 29 seconds

Yvette invests $300 each quarter in a fixed-interest mutual fund paying annual
interest of 7% compounded quarterly. How much will her account have in it at
the end of 11 years?

Answers

Answer:

Step-by-step explanation:

The formula for  calculating the amount after t years is expressed as;

A = P(1+r/n)*nt

P is the Principal (amount invested) = $300

r is the rate = 7% = 0.07

t is the time used to save = 11 years

n is time of compounding = 1/4 (quarterly)

Substitute;

A = 300 (1+0.07/(1/4))^(1/4)(11)

A = 300(1+4(0.07))^2.75

A = 300(1+0.28)^2.75

A = 300(1.28)^2.75

A = 300(1.9716)

A = 591.49

Hence the amount that will be in her account after 11 years is $591.49

Addison has a balance of $3,450 on her credit card that has an APR of 18%. She currently pays the minimum monthly payment of $86.25. If Addison wants to pay off her balance in 24 months, determine the monthly payments she would need to make. Choose the following modification with the least cuts to her current expenses that will allow Addison to pay off her balance in 24 months.

Income

b.
Addison can eliminate $45 from Food/Clothes and $41 from Entertainment.
c.
Addison can eliminate $25 from Food/Clothes and $22 from Entertainment.
d.
The minimum payment is enough to pay off the balance within 24 months.

ANSWER IS B)Addison can eliminate $45 from Food/Clothes and $41 from Entertainment.

Answers

Answer: (B) Addison can eliminate $45 from Food/Clothes and $41 from Entertainment.

Based on the information given, Addison should eliminate $45 from the money budget for Food/Clothes ($445.00) and $41 from Entertainment ($270.00).

Given the following data:

Balance = $3,450.APR = 18%.Monthly payment = $86.25.Time = 24 months (2 years).

How to calculate monthly payment.

Mathematically, the monthly payment for a credit card can be calculated by using this formula:

[tex]M=P(\frac{r}{1-(1+r)^{-nt}} )[/tex]

Where:

P is the principal.r is the interest rate.M is the monthly payment.t is the time.n is the number of times it's compounded.

In this scenario, Addison should eliminate $45 from the money budget for Food/Clothes ($445.00) and $41 from Entertainment ($270.00) because they are the least cuts to her current expenses and they would avail her an opportunity to pay off her balance in 24 months (2 years).

Step-by-step explanation:

Step 1: Define systems

6x = 10y - 10

x + y + 7 = 0

Step 2: Rewrite systems

6x = 10y - 10

y = -x - 7

Step 3: Solve for x

Substitute:                              6x = 10(-x - 7) - 10Distribute 10:                          6x = -10x - 70 - 10Combine like terms:              6x = -10x - 80Add 10x to both sides:          16x = -80Divide 16 on both sides:        x = -5

Step 4: Solve for y

Define:                                   x + y + 7 = 0Substitute:                             -5 + y + 7 = 0Combine like terms:              y + 2 = 0Subtract 2 on both sides:     y = -2
