Johnson’s Hardware randomly selects 125 of its customers and questions them to determine their overall customer satisfaction rat
Sphinxa [80]

Answer:

a. 92%

b. 4425

Step-by-step explanation:

So there are 5000 customers in total, and 100 were completely satisfied, and 15 were satisfied and 10 weren't satisfied a bit. so 100+15 is 115 so 115 people in total were satisfied out of 125 because there were 125, and 115+10 is 125 anyways. So 115/125 is .92, and you can convert that into a percentage, 92% of the 250 customers were satisfied so then 250*5 is 5000, so then just multiply 115 by 5 as well. You get 575. So 575 were satisfied out of the 5000 customers and 5000-575 are the people not satisfied, so 4425.

probably wrong because it doesnt sound right but just try it

During a sale, a store offered a 15% discount on a TV that originally sold for $900. After the sale, the discounted price of the
iVinArrow [24]
<h3>Answer:   98%</h3>

==================================================

Explanation:

The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.

85% of $900 = 0.85*900 = 765

After the 15% discount is applied, the customer would pay $765

---------

Then after the sale, the price is marked up by 15%

This means we'll multiply by 1.15 to indicate a 15% increase

1.15*765 = 879.75

Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.

---------

Afterwards, divide the value 879.75 over the original price of $900

879.75/900 = 0.9775

Move the decimal point two spots to the right to end up with 97.75%

That percentage rounds to 98% when rounding to the nearest whole percent.

A gold mine has two​ elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second.
Luba_88 [7]

Step-by-step explanation:

Time for equipment elevator = 11 seconds + 27 seconds = 38

Time for elevator for miners = 27 seconds

Speed of equipment Elevator = 7 feet/ sec

Speed of Miner elevator = 16 feet/ sec

Distance traveled by Equipment Elevator = Speed * time

                                               =  7 * 38 = 266

Distance traveled by Miner Elevator = Speed * time

                                                = 16 * 11 = 176

266 > 176

Therefore, The Equipment Elevator is deeper than the Miner Elevator

Depth of Equipment Elevator = 266m

Depth of Miner Elevator = 176m

I hope its Helpful,
