Calculate the circumference of a circle when the diameter is 5cm. Give your answer to 2
decimal places.

Answers

Answer 1

Answer:15.70

Step-by-step explanation:The formula for the circumference is 2πr. Plug-in the number provided into the formula, since diameter is double the radius you just divide the 5 by 2 to get 2.5.

So, 2π2.5=15.70

2 time π =6.28

6.28 time 2.5= 15.70

Find three consecutive positive integers such that the product of the first
two is 22 less than 11 times the third. (Type the answers in order - from
lowest to highest) *

Answers

Answer: 10,11,12

Step-by-step explanation:

1st integer= x-1

2nd integer= x

3rd integer= x+1

(x-1)(x) = 11(x+1)-22

x^2-x = 11x+11-22

simplify to: x^2-12x+11=0

factor to: (x-11)(x-1)

x=11, 1

1 doesn’t work because that would make the 1st integer equal to 0, and 0 isn’t a positive integer. So the three integers are 10, 11, and 12.

Answers

Answer:

AB, BC, AC

Step-by-step explanation:

(9x + 29)° + (93 - 5x)° + (10x + 2)° = 180°

9x + 29 + 93 - 5x + 10x + 2 = 180

14x + 124 = 180

14x = 56

x = 4

m∠A = (9(4) + 29)° = 65°

m∠B = [93- 5(4)]° = 73°

m∠C = (10(4) + 2)° = 42°  

m∠C < m∠A < m∠B

A door delivery florist wishes to estimate the proportion of people in his city that will purchase his flowers. Suppose the true proportion is 0.05. If 408 are sampled, what is the probability that the sample proportion will differ from the population proportion by greater than 0.03?

Answers

Answer:

 The probability is  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is  [tex]p = 0.05[/tex]

    The sample size is  n =  408

Generally the standard deviation of the sampling distribution is mathematically represented as

       [tex]\sigma = \sqrt{\frac{p (1- p)}{n} }[/tex]

=>    [tex]\sigma = \sqrt{\frac{ 0.05 (1- 0.05)}{408} }[/tex]

=>    [tex]\sigma = 0.0108[/tex]

Generally the probability that the sample proportion will differ from the population proportion by greater than 0.03 is mathematically represented as

        [tex]P( | \^ p - p| > 0.03) = P( \frac{|\^ p - p | }{\sigma } > \frac{0.03}{0.0108} )[/tex]

[tex]\frac{|\^ p -p |}{\sigma }  =  |Z| (The  \ standardized \  value\  of  \ |\^ p -p | )[/tex]

So    

       [tex]P( | \^ p - p| > 0.03) = P( |Z|> 2.778 )[/tex]

=>   [tex]P( | \^ p - p| > 0.03) = P( Z < 2.778) - P(Z < -2.777)[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.778  and  -2.778  is

     [tex]P( Z < 2.778) = 0.99727[/tex]

and

     [tex]P( Z < -2.778) = 0.0027347[/tex]

So

     [tex]P( | \^ p - p| > 0.03) = 0.99727 - 0.0027347[/tex]

=>  [tex]P( | \^ p - p| > 0.03) =0.9945[/tex]

A quantity with an initial value of 920 decays exponentially at a rate of 85% every week. What is the value of the quantity after 21 days, to the nearest hundredth?

Answers

Answer:

≈3.11

Step-by-step explanation:

The value of the quantity after 21 days, to the nearest hundredth, given the expoenential decay is 3.11.

What is the value of the quantity after 21 days?

When a quantity decays , it means that the value of the quantity declines with the passage of time.

The formula that can be used to determine the value of the quantity after a number of weeks is :

FV = P (1 - r)^n

Where:

FV = Future valueP =initial valueR =rate of decayN = number of weeks = 21/7 = 3 weeks

920 x (1 - 0.85)^3

920 x 0.15^3 = 3.11

A Their original bill cost $50.00, but they had a coupon for 20% off their meal. Find the discounted price (before tax and tip).
B A sales tax of 7% was added. What was the total amount including sales tax?
C The group chose to tip 20%. What is the total amount that their bill cost including tax and tip?

Answers

Answer:

A. 10.00, so total price is currently 40.00

B. 42.8

C. Total amount is 51.36

Step-by-step explanation:

20% of 50 is 10. Taking off 10% (your discount) would make it 40.

7% of 40 is 2.8. The total amount is now 42.8

20% (your tip) of 42.8 = 8.56.

42.8 + 8.56 = 51.36.

51.36 is your final cost.
