dinners frequently add a 15% tip when charging a meal to a credit card. what is the price of the meal without the tip amount charged is $18.40? how much was the tip?

Answer:

53.3%

Step-by-step explanation:

Here we will use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

In this case, n = 11, r ≥ 7, p = 0.6, and q = 0.4.

P = ₁₁C₇ (0.6)⁷ (0.4)⁴ + ₁₁C₈ (0.6)⁸ (0.4)³ + ₁₁C₉ (0.6)⁹ (0.4)² + ₁₁C₁₀ (0.6)¹⁰ (0.4)¹ + ₁₁C₁₁ (0.6)¹¹ (0.4)⁰

P = 0.236 + 0.177 + 0.089 + 0.027 + 0.004

P = 0.533

Answer:

b. total fees divided by loan amount

Step-by-step explanation:

The interest rate on a payday loan is usually calculated by dividing the total fees accrued in the loan repayment calculation by the exact loan amount.

Doing this will result in determining the interest rate used in a loan and it’s usually important to ensure accountability and also making sure the exact rate contained in the Loan application agreement Is the same as what is used later on.

Answer:

Since the sum is 38, y must be 15. And indeed the difference between 23 and 15 is 8, so it's correct.

Answer:

15 & 23

Step-by-step explanation:

I used an insert and check kind of method. Basically you insert numbers and check if they work for both equations. the equations are as follow:

X + Y = 38

X - Y = 8

I inserted various combinations of numbers and we'll use one as reference.

I used 16 and 22. 16 and 22 correctly fits the requirements of the first equation but when we do 22 - 16 we see that it equals 6. this is 2 off from the second equation. Using this info I ask myself, was the answer close or far from the answer needed.

Hope this answered any questions. please comment on this if you need any othern have a nice day!

Answer:

[tex]range=5.1[/tex]

Step-by-step explanation:

The range of a set is found by subtracting the lowest number from the greatest number.

The greatest number is 2.8 , and the lowest is -2.3. Subtract the values:

[tex]2.8-(-2.3)[/tex]

Two negatives make a positive, so:

[tex]2.8+2.3=5.1[/tex]

Answer:

20 X 40 = 800 (split into 2 fourths) = 40

Step-by-step explanation

20 x 40 = 800;

For 2 necklaces she can split 800 into fourths.

800 - 40 = 80. (1 fourth)

80 - 40 = 40 (2 fourths)

40 - 40 = 0 (3 fourths)

She could split 800 into 2 fourths to get a number more than 0 and less then 42.

The best estimate of rounding 42 is 40. Because 40 is closer to 42.

Answer:

Option 3: 12 is the correct answer.

Step-by-step explanation:

Given functions are:

[tex]f(x) = 16x-30\\g(x) = 14x-6[/tex]

In order to find the value of x on which (f-g)(x) will be zero, first of all we have to find (f-g)(x) and then equate it equal to zero to find the value of  that will make (f-g)(x)

So,

[tex](f-g)(x) = f(x) - g(x)\\= (16x-30)-(14x-6)\\=16x-30-14x+6\\= 2x-24[/tex]

Now to find the value of x on which (f-g)(x) will be zero, putting (f-g)(x) = 0

[tex](f-g)(x) = 0\\2x-24 = 0[/tex]

Adding 24 on both sides

[tex]2x-24+24 = 0+24\\2x = 24[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2} = \frac{24}{2}\\x = 12[/tex]

For x=12, (f-g)(x) will be zero.

Hence,

Option 3: 12 is the correct answer.

Answer:

"S" (similar fractions)

Step-by-step explanation:

Since "similar fraction" are those with the same denominator, in our case, since 2/3 and 1/3 have both the same denominator "3", these are similar fractions.

Answer:

I do not agree because if there is an equation like 7+8 the answers would not be equal. They can only be equal if you add 8 to each side of the same number. For example, 7+7 with 8 added on both sides would be equal. But Maggie says that it can be equal for any equation. Therefore, Maggie is wrong.

Answer:

$1017.19

Step-by-step explanation:

First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.

Answer:

Asumming that you are rounding to the nearest hundreth:

1,017.19

Step-by-step explanation:

Find [tex]\frac{1}{8}[/tex] of 2,712.5 to find how much money Paulo spends on his car.

[tex]\frac{1}{8}[/tex] = .125

Multiply 2,712.5 by .125

2,712.5 × .125 = 339.0625 ≈ 339.06

Now, find [tex]\frac{1}{4}[/tex] of 2,712.5 to find how much paulo spends on his rent.

[tex]\frac{1}{4}[/tex] = .25

Multiply 2,712.5 by .25

2,712.5 × .25 = 678.125 ≈ 678.13

Add the two values together to get your answer

339.09 +

678.13

----------

1,017.19

(Another way to dolve this problem would be to find [tex]\frac{5}{8}[/tex] of 2,712.5 and subtract it from the origional value, 2,712.5)

Answer:

The birds travel at an average velocity of 122.2 miles per day

Step-by-step explanation:

The arctic terns fly a total distance of 22,000 miles in their yearly migration from the Arctic to the Antarctic and back again.

The average speed is the ratio between the total distance traveled by the time they took to travel.

Assume we take an average month of 30 days, then the time the arctic terns take to travel the 11,000 miles back is 30*3= 90 days.

The average velocity is

[tex]\displaystyle v=\frac{11,000}{90}=122.2[/tex]

v=122.2 miles/day

The birds travel at an average velocity of 122.2 miles per day

Answer:

The artic tern flies 11000 miles about 3 months at an average velocity of 122.222 miles per day.
