Some friends went to lunch and split the bill equally. If each person paid $6.75, how many people went to lunch thinking. Use a

diagram or equation to explain your thinking. The total is 27$. 27 divided by 6.75 is 4. Suppose
$7.00 was added to the bill for a dessert tha everyone shared. How much more would each person have to pay?​

Answer:

With $7.00 dollars added to the original cost, each of the four people would have to pay $8.50  

 

27 + 7 = 34  

34/7 = 8.50  

$8.50 - $6.75 = $1.75  

$1.75 more with the new total. Hopefully this helps! Feel free to mark brainliest!

Answer:

Step-by-step explanation:

We’ve all been there. You know how it goes… you’re out with your friends, you order an inexpensive item on the menu to be your frugal/responsible self, and then the bill comes and someone says, “Let’s just split it equally! That’ll make it easy!” Then, out come the wallets, credit cards, and cash. It’s awkward to pipe up and say, “Uh, but, uh, I only had the $7 thing not the $35 thing, and no wine or dessert or appetizers!”

No one what’s to be the cheap/poor/miser in the group. I’ve been there. Trust me. It’s not a fun place to be. So, how do you deal?

Lucky for us, a reader wrote in with that very question:

“This weekend I went out to a friend’s birthday dinner which was out at a restaurant. We’d recently gone out to eat for this friends’ sisters birthday and everyone in the group paid for themselves. Additionally, during all the other previous times we went out, that I can remember, we all pay for ourselves.

Well this weekend, when the bill came, one of the guests at the table suggested that we all split the bill 6 ways to make things simpler and so that the birthday girl wouldn’t have to pay. This was devastating to me and my wallet! I’d looked at the menu before getting to the restaurant and chose one of the cheapest entrees, which was $15.75. With tax and tip I figured my bill would be no more than about $20. I even brought about that amount of cash. The final bill was $300. Split six ways and its $50!!! I sucked it up and paid $50 because I was too embarrassed to say anything, particularly since I only really knew the birthday girl, her husband and her sister. Any advice on what to do in those situations or what to do before the bill comes to avoid those types of situations?”

Erm. Completely awkward, right.

Two well-known aviation training schools are being compared using random samples of their graduates. It is found that 70 of 140
egoroff_w [7]

Answer:

Step-by-step explanation:

Given that two well-known aviation training schools are being compared using random samples of their graduates

Fly more academy 70 of 140

Blue Yonder   104 of 260

Combined pass = (70+104) out of (140+260)

a) Pooled proportion=\frac{174}{400} \\=0.435

b) H0: p1 = p2

Ha: p1 ≠p2

(two tailed test)

p difference= \frac{70}{140} -\frac{104}{260} =0.10

std error for difference (using pooled proportion) = \sqrt{\frac{0.435*0.565}{400} } \\=0.0248

Test statistic = p difff/std error = 4.034

c) Critical value for 0.05 is 1.96

d) p value is < 0.005

Since p < 0.05 our significant level we reject H0

There is significant difference between the two proportions.

A new car is purchased for 15300 dollars. The value of the car depreciates at 14.25% per year. What will the value of the car be
Andrei [34K]

Answer:

\$6,082.70  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

V=P(1-r)^{x}  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

P=\$15,300\\r=14.25\%=0.1425\\x=6\ years

substitute in the formula

V=15,300(1-0.1425)^{6}  

V=15,300(0.8575)^{6}  

V=\$6,082.70

Tia Veronica Pam and Lily are sisters. Tia is eight years old and she’s two years older than Pam. Pam is five years younger than
Nastasia [14]

Answer:

Pam (6 years), Tia(8 years), Veronica(11 years) , Lily (15 years)

Step-by-step explanation:

Age of Tia = 8 years

______________________________________________

Given Tia is  2 years older than Pam

mathematically

age  of Pam + 2 years = age of Tia

age  of Pam + 2 years = 8 years

age  of Pam  = 8 years- 2 years = 6 years

______________________________________________

Given Pam is five years younger than Veronica

we can infer that age of veronica is age of Pam + 5 more years

mathematically

age  of Pam + 5 years = age of Veronica

6 years + 5 years = age of Veronica

age  of Veronica   = 11 years

______________________________________________

Given Veronica is four years younger than Lily

we can infer that age of Veronica is (age of Lily - 4  years)

mathematically

age of Veronica = age of lily - 4 years

11 years = age of lily - 4 years

age of lily = 11 years + 4 years = 15 years

age  of lily   = 15 years

______________________________________________

Arranging the list from youngest  to oldest we have

age  of Pam  = 6 years

Age of Tia = 8 years

age  of Veronica   = 11 years

age  of lily   = 15 years

Arranging sisters in order of youngest  to oldest

Pam, Tia, Veronica , Lily
