The following graph portrays the distribution of the number of spicy chicken sandwiches sold at a nearby Wendy's for the last 141 days.
The mean number of sandwiches sold per day is 91.9 and the standard deviation is 4.67. (Round your answers to 2 decimal places.)
If we use the Empirical Rule, on 68 percent of the days sales will be between
95 percent of the days sales will be between
68% of the day's sales will be between 87.23 and 96.57 and on 95% of the days, sales will be between 82.56 and 101.24.
What is the empirical rule?If your distribution follows a normal distribution, the standard deviation and mean can tell you where the majority of the data are.
We have:
The mean number of sandwiches sold per day is 91.9 and the standard deviation is 4.67.
As we know, from the empirical rule, 68% of the data will lie in one standard deviation of the mean, i.e., in the interval with the endpoints x±s
for samples and with endpoints u±б for the population.
x = 91.9
s = 4.67
x - s = 91.9 - 4.67 = 87.23
x + s = 91.9 + 4.67 = 96.57
68% of the day's sales will be between 87.23 and 96.57
95% of the data will lie within two standard deviations of the mean, which means in the interval with the endpoints x±2s for samples and with endpoints u±б population.
x - 2s = 82.56
x + 2s = 101.24
On 95% of the days, sales will be between 82.56 and 101.24
Thus, 68% of the day's sales will be between 87.23 and 96.57 and on 95% of the days, sales will be between 82.56 and 101.24.

A box without a top is to be made from a rectangular piece of cardboard, with dimensions 4 in. by 8 in., by cutting out square corners with side length x and folding up the sides.
(a) Write an equation for the volume V of the box in terms of x.
(b) Use technology to estimate the value of x, to the nearest tenth, that gives the greatest volume. Explain your process.
Step-by-step explanation:
Part A:
So the height is going to be x when you fold the sides up. So that's one part of the volume but for the width it was going to be 4 but since two corners were cut out with the length x the new width is going to be (4-2x). The same thing applies for the length which should be 8 inches but since two corners were removed with the length x it's now (8-2x)
v = x(4-2x)(8-2x)
Part B:
The volume can be graphed although there must be a domain restriction since the height, width, or length cannot be negative. So let's look at each part of the equation
so for the x in front it must be greater than 0 to make sense
for the (4-2x), the x must be less than 2 or else the width is negative.
for the (8-2x) the x must be less than 4 or else the length is negative
so the domain is going to be restricted to 0 < x < 2 so all the dimensions are greater than 0
By using a graphing calculator you can see the maximum of the given equation with the domain restrictions is 0.845 which gives a volume of 12.317
A chain weighs 12 pounds per foot. How many ounces will 7 inches weigh?
Answer:
The chain of the length 7 inches weighs 112 ounces.
Step-by-step explanation:
As we know there are 12 inches in a foot and 16 ounces in a pound
That is 1 foot = 12 inches.
and 1 pound = 16 ounces.
Given that the weight of the chain that is 1 foot long = 12 pounds
So weight of the chain per inch is = 12/12
which is equal to 1 pound
and according to the formula 1 pound = 16 ounces
So weight of the chain per inch is = 16 ounces
therefore weight of the chain that is 7 inch long = 7 × 16
that is 112 ounces.

c. 36%
d. 1.5%
The interest rate is 36% per year if the value of a savings account can be found using the equation 300(1.03)²⁴ option (c) is correct.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
We have:
The value of a savings account can be found using the equation =
= 300(1.03)²⁴
From the function:
F(x) = a(1+r)ˣ
On compare:
1 + r = 1.03
r = 0.03
or
r = 3% monthly
r = 3×12 = 36% yearly
Thus, the interest rate is 36% per year if the value of a savings account can be found using the equation 300(1.03)²⁴ option (c) is correct.

answer the following function, algebra 1.
Answer:
g(f(x)) = 1x² + 1
Step-by-step explanation:
We are given:
f(x) = x² - 1
g(x) = x + 2
And we want to find g(f(x)).
To do this, we substitute f(x) as x in x+2 (the expression that is equal to g(x)), as g(f(x)) is saying that f(x) is the value of x in g(x).
So, this will be:
g(f(x)) = x² - 1 + 2
Simplify
g(f(x)) = x² + 1
In your system, place 1 in front of x² - this is the coefficient of x², and also 1 after that - this is a constant.
Circumference and area of a piece of glass cabinet which has a diameter of 1.8m
Answer:
circumference: 5.65 m
area: 2.54 m
Step-by-step explanation:
here are some relationships between measurements of a circle:
C = π d
(Circumference = pi · diameter)
A = π r²
(Area = pi · radius²)
[π / pi is the ratio of a circle's circumference to its diameter. this ratio is actually a constant across all circles, which is where we derive our circumference and area formula from. π ≈ 3.14159]
so, let's work on finding the circumference first.
C = π d
we know the diameter = 1.8, and we know that π ≈ 3.14159
so, if we multiply these two numbers together, we will get the circumference
[this equation makes sense if you read my explanation of pi]
1.8 × 3.14159 = 5.654862
We can round this number to 5.65
So, the circumference of our circle = 5.65 m
now, let's find the area
A = π r²
we know that π ≈ 3.14159, but we still haven't found "r"
r, or radius, is the measurement from the center of a circle to any point of the circle. Because the diameter is the measurement from one side of a circle to the opposite side, diameter = twice the radius
this means we can take our diameter, 1.8, and divide it by 2 to find our radius.
1.8 / 2 = 0.9
now, we can solve for area.
π ≈ 3.14159 , r = 0.9
A = π r²
A = π (0.9)²
A = (3.14159) (0.81)
A = 2.5446879
we can round this area to 2.54
so, the area of our circle = 2.54 m

Considering the multiplication of mixed fractions, [tex]\frac{21}{6}[/tex] or 3.5 hours was sunny that day.
Multiplication of mixed fractionsTo multiply mixed fractions, it is necessary to transform these fractions into improper fractions. To do this, the whole part is multiplied by the denominator of the fraction that accompanies it. The result of the multiplication is added to the numerator of the fraction that accompanies it, and it will be the denominator of the new fraction, while the denominator remains the same.
After transforming the mixed fractions to be multiplied into improper fractions, they are multiplied. To do this, it is necessary to multiply the numerators of the two fractions, and the denominators of the fractions. If the resulting product needs to be simplified to lowest terms, divide the numerator and denominator by common factors.
Sunny hoursOn a day in winnipeg with 10[tex]\frac{1}{2}[/tex] h of daylight, it was sunny for [tex]\frac{1}{3}[/tex] of that time. This is:
