A family of eight dines in a popular franchise restaurant. The restaurant has a policy of automatically including a standard tip to the final bill for parties larger than six people. The bill for the meal included a total of $58.25 in food and beverage sales, plus a standard tip of $10.49. What percent of the food and beverage sales does the restaurant consider to be a standard tip for parties larger than six?
A family dines in a popular franchise restaurant that has a policy of automatically including a 20% tip on all food and beverage sales before coupon discounts are applied. What is the family’s total bill amount if their food and beverages totaled $94.20 and they used a 15% off coupon? (HINT: Create more than one model.) DONT ANSWER THE QUESTION JUST PUT THE EQUATIONS
Answer:
A) t=0.2(60.5)
B) d=0.15(34)
C) t=0.9(157.3)
D) p=100(10.49/58.25)
E) t=0.85(94.2+0.2(94.2))
Step-by-step explanation:
A)
Let the tip be represented by t. The tip is 20% of $60.50:
t=0.2(60.5)
B)
Let the money they save be represented by d. Their discount is 15% of $34:
d=0.15(34)
C)
Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:
t=0.9(157.3)
D)
Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:
p=100(10.49/58.25)
E)
First find the total after the tip but before the coupon.
Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)
Now find their final total.
Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:
t=0.85(94.2+0.2(94.2))

a 440m long road is being repaired at the end of 3 days the workers had repaired 3/4 of the road what length of the road is left unrepaired
THE ANSWER IS 110 m
Workers had repaired 3/4 of the road
it means3/4×440 is been repaired
length of repaired road is 3×110 = 330m
length of unrepaired road = Length of to road - length of repaired road
i.e. = 440-330 = 110m

What is the 12th term of the geometric sequence where *
A7 = 7 and 10 = -56
O-448
0-224
O -112
0 -96
Answer:
-224
Step-by-step explanation:
Geometric sequence is given by An = A*R^(n-1)
Given A7 = 7 and A10 = -56
A10/A7 = -8 = R^(10-7)
R^3 = -8
R = -2
A12 = A10*R^2
= -56*-2^2
= -224
Answer:
Step-by-step explanation:
A7 = 7
A10 = -56
7xRxRxR = -56
R = -2
A12 = A10xRxR
= -56 x -2 x -2
= 224
Find the equation of a line perpendicular to 4x - 5y = -1 that contains the point (5, -4)
Answer:
y = -5/4x + 2 1/4
Step-by-step explanation:
you would start by changing the equation to point intercept form
4x + 1 = 5y
4/5y + 1/5 = y
then you fill in the points and change the slope to -5/4 (reciprocal and opposite sign)
-4 = -5/4(5) + b
-4 = -6.25 + b
2.25 = b

Find the area of this
irregular figure.
9 ft
[ ? ] square feet
8 ft
15 ft
26 ft
Answer:
426 ft^2.
Step-by-step explanation:
It area = area of the rectangle + area of the triangle
= 15 * 26 + 1/2 * 8 * 9
= 390 + 1/2*8*9
= 390 + 36
= 426 ft^2.
The area of the figure given is 426 ft^2.
How to find the surface area of some object?Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.
Area = Area of the rectangle + Area of the triangle
Area = 15 * 26 + 1/2 * 8 * 9
Area = 390 + 1/2*8*9
Area = 390 + 36
Area = 426 ft^2.
Therefore, the area of the figure given is 426 ft^2.

Step-by-step explanation:
A food scientist takes a random sample of 25 cereals in order to test the claim that the mean fiber content is less than 2.5 grams. The graphs of the data and two types of hypothesis test output are provided below. Determine which output should be used and state the conclusion of this test at the 5% significance level.
Answer:
Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.
Step-by-step explanation:
From the graphs given the more appropriate is one sample t- test
One sample t- test is used and the results are
Hypothesis Test Fiber
Sample Mean 2.62
Sample St. Dev 3.492
Degrees of Freedom 24
t- test statistic 0.1718
p- value 0.5675
the critical region for this test at ∝= 0.05 is t < -1.711
There is not enough evidence to reject the null hypothesis.
Since the calculated t= 0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not less than 2.5 grams.T

Jennifer age 18 initially invested $1000 at 8% interest how old would she be when the account is $128,000
Answer:
2,304 years old
Step-by-step explanation:
Given: Jennifer age = 18, Invested = $1000 at 8% interest
To find: How old would she be when the account is $128,000?
Wrong solution
Solution: To figure out how old she will be when her account is $128,000, simply find the difference between her current account value by her current age, by dividing. Then multiply the result by the future account value.
Step 1: [tex]\frac{1000}{18} = 55.5555555556[/tex]
Rounding, that is; 55.56
Step 2: Now, multiply the result by the future account value.
[tex]55.56[/tex] × [tex]128000 = 7111680[/tex]
Correct solution
Solution: To find out how old she will be when her account is $128,000, set up a fraction;
[tex]\frac{1000}{8} = \frac{12800}{x}[/tex]
Step 1: Divide the numbers
[tex]\frac{1000}{8} = \frac{128000}{x} \\\\\frac{500}{9} = \frac{128000}{x}[/tex]
Step 2: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500}{9} = \frac{128000}{x} \\\\x * \frac{500}{9} = x * \frac{128000}{x}[/tex]
Step 3: Cancel multiplied terms that are in the denominator
[tex]x *\frac{500}{9} = x * \frac{128000}{x} \\\\x * \frac{500}{9} = 128000[/tex]
Step 4: Re-order terms so constants are on the left
[tex]x * \frac{500}{9} = 128000\\\\\frac{500}{9} x= 128000[/tex]
Step 5: Combine multiplied terms into a single fraction
[tex]\frac{500}{9} x = 128000\\\\\frac{500x}{9} = 128000[/tex]
Step 6: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500x}{9} = 128000\\\\9 * \frac{500x}{9} = 9 * 128000[/tex]
Step 7: Cancel multiplied terms that are in the denominator
[tex]9 * \frac{500x}{9} = 9 * 128000\\500

What is the y-intercept in the equation y = 4x - 3?
answer: -3
remember the equation y = mx + b
m is the slope, and b is the y-intercept
so in the equation y = 4x - 3,
4 replaces the m as the slope and -3 replaces b for the y-intercept
so -3 is your answer

-3

P(A) = 0.44, P(B) = 0.36 and P(A and B) = 0.20 .
P(B ∣ not A)=
Answer:
0.2857
Step-by-step explanation:
P(B | not A)
Recall :
P(A | B) = P(A n B) / P(B)
Hence ;
P(B | not A) = P(B and not A) / P(not A)
P(not A) = 1 - P(A) = 1 - 0.44 = 0.56
P(B and not A) = P(B) - P(A and B) = 0.36 - 0.20 = 0.16
Hence,
P(B | not A) =P(B and not A) / P(not A) = 0.16 / 0.56
= 0.2857

A particular fruit's weights are normally distributed, with a mean of 406 grams and a standard deviation of 9 grams.
If you pick one fruit at random, what is the probability that it will weigh between 379 grams and 394 grams
Answer:
P(379<X<394) = 0.0899 = 8.99%
Step-by-step explanation:
P(379<X<394) = normalcdf(379,394,406,9) = 0.0898613146 ≅ 8.99%
Therefore, if you pick one fruit at random, the probability that it will weigh between 379 grams and 394 grams is 0.0899 or about an 8.99% chance of occurence.
