Answer:

= $44.19

Step-by-step explanation:

APR = 19%

Billing cycle = 30 days

Balance = $2830

Let's first find the daily rate,

Daily rate =  \frac{0.19}{365} = 0.000521

The daily rate = 0.000521

To calculate the amount Shirley was charged interest for the billing cycle, we use:

Daily rate * billing cycle * balance

Where,

Daily rate

=  \frac{0.19}{365}

Billing cycle = 30 days

Balance = $2830

Therefore, expression to be used =

(\frac{0.19}{365}  * 30) * 2830 \\= $44.19

PLEASEE HELPPP!!!
Harlamova29_29 [7]

Answer:

The amount is $649.46 and the interest is $49.46.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount  

P = principal or amount of money deposited,

r = annual interest rate  

n = number of times compounded per year

t = time in years

In this example we have

P=$600 , r=8% , n=4 and t=1 years

After plugging the given information we have

AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46

STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:

A649.46II=P+I=600+I=649.46−600=49.46

Minute Maid states that a bottle of juice contains 473 mL. Consumer groups are interested in determining if the bottles contain
kramer

Answer:

The average contents of all bottles of juice in the population

\mu = 473\text{ mL}

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  473 mL

Sample mean, \bar{x} = 472 mL

Sample size, n = 30

Sample standard deviation, s = 0.2

First, we design the null and the alternate hypothesis

H_{0}: \mu = 473\text{ mL}\\H_A: \mu < 473\text{ mL}

Representation of \mu

  • It is the population parameter for mean.
  • Thus, it represents the average contents of all bottles of juice in the population, which is 473 mL.

A merry go round revolves 2 times per minute, jack is 10 feet from the center while bob is 14 feet from the center
Nesterboy [21]

Answer:

Jack's linear speed is 126ft/min

Bob's linear speed is 176ft/min

Step-by-step explanation:

First of all, find the circumference of both circles given the radius; Jack, 2<em>pi</em>r (10)=63ft. Bob 2<em>pi</em>r(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.
