Answer:

2/3

Step-by-step explanation:

if she uses 1/3 for one she uses 2/3 for 2 because 1/3 times 2 is 2/3

step 1 Address formula, input parameters & values

1/3 and 2/1

1/3 times 2= ?

step 2 Multiply both numerators

= 1 x 2

= 2

step 3 Multiply both denominators

= 3 x 1

= 3

step 4 Use above values of step 2 & 3, and rewrite as below

= 2/3

thus, 2/3 is equivalent fraction for 1/3 times of 2.

Assume the time required to complete a product is normally distributed with a mean 3.2 hours and standard deviation .4 hours. Ho

Alex787 [66]

Answer: 3.712 hours or more

Step-by-step explanation:

Let X be the random variable that denotes the time required to complete a product.

X is normally distributed.

$X\sim N(\mu=3.2\text{ hours},\ \sigma=0.4\text{ hours} )$

Let x be the times it takes to complete a random unit in order to be in the top 10% (right tail) of the time distribution.

Then, $P(\dfrac{X-\mu}{\sigma}>\dfrac{x-\mu}{\sigma})=0.10$

$P(z>\dfrac{x-3.2}{\sigma})=0.10\ \ \ [z=\dfrac{x-\mu}{\sigma}]$

As, $P(z>1.28)=0.10$ [By z-table]

Then,

$\dfrac{x-3.2}{0.4}=1.28\\\\\Rightarrow\ x=0.4\times1.28+3.2\\\\\Rightarrow\ x=3.712$

So, it will take 3.712 hours or more to complete a random unit in order to be in the top 10% (right tail) of the time distribution.

Part A: Joel uses the incorrect expression 0.95(190)(0.8) to calculate that the computer will cost him a total of $144.40. Descr

UkoKoshka [18]

Complete question:

Joelwants to buy a new tablet computer from a store having a 20% off sale on all tablet. The tablet he wants has an original cost of $190. He also wants to make sure he has enough money to pay the 5% sales tax.

Answer:

$159.60

Step-by-step explanation:

Given the following :

Sales tax = 5%

Percentage discount = 20%

Original cost = $190

Joel's incorrect expression : 0.95(190)(0.8)

Joel's mistake is the 0.95 which is equivalent to 95% used in Calculating the total cost of the computer. The sales tax increases the total cost of the computer and instead of subtracting 5% sales tax, it should be added.

B.) 20% discount = 0.2 will be deducted from 100%(1)

1 - 0.2 = 0.8

5% sales tax = 0.05 will be added :

1 + 0.05 = 1.05

Original cost = $190

Therefore,

Total cost : Original cost * sales tax * discount

Total cost = $190 * 1.05 * 0.8

Total cost = $159.60

Using the standard 28/36 ratio, determine the maximum allowable recurring debt for someone with a

Mumz [18]

The maximum allowable recurring debt for someone with a monthly income of $54.875 is $4.39.

<h3 /><h3>Maximum allowable recurring debt:</h3>

Using this formula

Maximum allowable recurring debt=Ratio×Monthly income

Where:

Ratio=28/36

Monthly income=$54.875

Let plug in the formula

Maximum allowable recurring debt=(36%×$54.875)-(28%×$54.875)

Maximum allowable recurring debt=$19.755-$15.365

Maximum allowable recurring debt=$4.39

Inconclusion the maximum allowable recurring debt for someone with a monthly income of $54.875 is $4.39.
