Market research indicates that a new product has the potential to make the company an additional $1.6 million, with a standard deviation of $2.5 million. If these estimates were based on a sample of 12 customers from a normally distributed data set, what would be the 95% confidence interval
Answer:
(0.01, 3.19)
Step-by-step explanation:
Given that :
Mean (m) = 1.6 million
Standard deviation (s) = 2.5 million
α = 0.05
Sample size (n) = 12
Confidence interval :
m ± t(α, df = n - 1) * standard error
Standard Error = s/√n = 2.5 / √12 = 0.7216878
t0.05,11 = 2.200985 (t value calculator)
Hence,
1.6 ± 2.200985(0.7216878)
Lower bound /
1.6 - 2.200985(0.7216878) = 0.011575977517
Upper bound:
1.6 + 2.200985(0.7216878) = 3.188424022483
(0.01, 3.19)

Answer:
D. [tex]\frac{AB}{VW}[/tex] = [tex]\frac{CD}{XY}[/tex]
Step-by-step explanation:
You have to make sure that the proportions of both figures are matched correctly. These are the pairings:
AB is like VW but bigger.
CB is like XW but bigger.
AE is like VZ but bigger.
CD is like XY but bigger.
ED is like ZY but bigger.
Thus, the only correct comparison would have been [tex]\frac{AB}{VW}[/tex] = [tex]\frac{CD}{XY}[/tex]
A beach ball is inflated so its diameter increases from 12 inches to 12.5 inches. Given that the formula for the volume of a sphere is V=4/3π,r^3 the change in the volume of the beach ball using differentials is approximately.
a. 367π cubic inches.
b. 727π cubic inches.
c. 1447π cubic inches.
d. 288.7π cubic inches.
Answer:
V = 36π cubic inches.
Step-by-step explanation:
From the given information:
The volume of the sphere is [tex]V = \dfrac{4}{3} \pi r^3[/tex]
Suppose the diameter is represented by P.
i.e P = 2r
and r = P/2
∴
[tex]V = \dfrac{4}{3} \pi ( \dfrac{P}{2})^3[/tex]
Differentiating both sides;
[tex]dV = \dfrac{4}{3} \pi \times 3 ( \dfrac{P}{2})^2 \times \dfrac{1}{2} \times dP[/tex]
[tex]dV = \dfrac{1}{2} \pi P^2 \ dP[/tex]
here;
P = 12
dP = 12.5 - 12
dP = 0.5
∴
[tex]\dfrac{1}{2} \pi ( 12)^2 \times 0.5[/tex]
= 36π
Thus, the volume is V = 36π cubic inches.

A pizza chain offers cheese pizzas with a choice of these toppings:
pepperoni, onion, sausage, mushrooms, and anchovies.
a) Explain why the pizza chain can claim to offer 32 different pizzas.
b) Another pizza chain claims that with its choice of toppings, it can
create just over 1000 pizzas. What is the minimum number of
toppings it must offer?
Step-by-step explanation:
The pizza chain has 5 different topings.
Number of different pizzas = 2⁵ = 32.
We have 2^n >= 1000.
Since 2⁹ = 512 and 2¹⁰ = 1024,
the minimum number of toppings is 10.
Rosa bought a storage container in the shape of a cube to store clothes. The storage container has a volume of 950 cubic inches. What is the length of one side of the storage container? Estimate the length to the nearest integer.
Answer:
10inStep-by-step explanation:
The volume of a cube is expressed as;
V = L³
L is the length of one side of the cube
Given
V = 950in³
Required
Length of one side of the cube
Substitute the given parameters into the formula and get L as shown;
V = 950in³
950 = L³
Take the cube root of both sides
∛950 = ∛L³
∛950 = L
L = ∛950
L = 9.83
Hence the length of one side to nearest integer is 10 inches

By mid-point theorem- If the line segment adjoins midpoints of any of the sides of a triangle, then the line segment is said to be parallel to the remaining side, and it measures to half of the third side.
Here, [tex]DE[/tex] is the line segment joining the mid-points of the two sides of the triangle [tex]ABC[/tex].
[tex]BD=DA[/tex] i.e., [tex]D[/tex] is the midpoint of [tex]AB[/tex]
[tex]BE=EC[/tex] i.e., [tex]E[/tex] is the midpoint of [tex]BC[/tex]
So, [tex]DE||AC[/tex] and [tex]DE=\dfrac{AC}{2}[/tex]

The local recreation center charges members a registration fee and a separate monthly membership fee. The equation of the function given models the total fee, f(x), in dollars, that a person pays for x months of membership.
Complete question :
The local recreation center charges members a registration fee and a separate monthly membership fee. The equation of the function given models the total fee, f(x), in dollars, that a person pays for x months of membership.
f(x)=25x+50
What does the number 25 represent?
A. the initial registration fee
B. the number of months that a person is a member
C. the monthly membership fee
D. the total amount that a member pays in fees
Answer:
C. the monthly membership fee
Step-by-step explanation:
Given the function :
f(x)=25x+50
The function f(x) can be written thus :
Cost = (monthly membership fee * Number of months) + initial registration fee
Comparing the function with the linear equation model:
y = mx + c
50 corresponds to c (intercept) which is the initial registration fee being charged.
m = slope = monthly fee paid
Hence, 25 represents the monthly fee paid

Step-by-step explanation:
Simple interest = PTR/100
= £1500x2x3/100
= 15x2x3 = 90
£90 is simple interest
So amount = Principcal + Interest
Amount = 1500 + 90
