The owner of a popular coffee shop wants to determine if there is a difference between the proportion of customers
who use their own cups when they purchase a coffee beverage, and the proportion of customers who use their own
cups when they purchase an espresso beverage. Customers using their own cups get a 5% discount, which is
displayed on the receipt. The owner randomly selects 50 receipts from all coffee purchases and 50 receipts from all
espresso purchases. For coffee purchases, 24 receipts showed that the customer used their own cup. For espresso
purchases, 18 receipts showed the customer used their own cup. The owner wants to construct a 95% confidence
interval for the difference in the proportions of customers who use their own cups. Are the conditions for inference
met?
Yes, the conditions for inference are met.
No, the 10% condition is not met.
No, the randomness condition is not met.

find the missing side of each triangle
• Hypotenuse (H) = 15 in
• Base (B) = 12 in
To calculate :• Perpendicular (P) [x]
Calculation :By using pythagoras property,
[tex] \longmapsto \sf { H^2 =B^2 + P^2 } [/tex]
[tex] \longmapsto \sf { (15)^2 =(12)^2 +(x)^2 } [/tex]
[tex] \longmapsto \sf { x^2 = (15)^2 - (12)^2 } [/tex]
[tex] \longmapsto \sf { x^2 = 225 - 144 } [/tex]
[tex] \longmapsto \sf { x^2 = 81 } [/tex]
[tex] \longmapsto \sf { x = \sqrt{81} } [/tex]

Step-by-step explanation:
Give the limits of integration for evaluating the integral
∭f(r,θ,z)dz r dr dθ
as an iterated integral over the region that is bounded below by the plane z = 0, on the side by the cylinder r=cosθ and on top by the paraboloid z=3r^2.
Answer:
θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3
Step-by-step explanation:
Since the integration is in cylindrical coordinates, θ is integrated from 0 to 2π.
Since r = cosθ
when θ = 0, r = cos0 = 1
when θ = 2π, r = cos2π = -1
Since the region is bounded below by the plane z = 0, and on the top by the paraboloid z = 3r², z is integrated from z = 0 to z = 3r².
So, when r = 1, z = 3r² = 3(1)² = 3
when r = -1, z = 3r² = 3(-1)² = 3
So, the limits of integration of
∭f(r,θ,z)dz r dr dθ are θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Taiga’s teacher asked him to draw a polygon with vertices (–4, –5), (–5, 2), (–5, 3), (–4, 5), (2, 3), and (–3, 0) and to identify the polygon. Taiga drew the polygon below and identified it as a heptagon.
Which explains whether Taiga is correct?
Taiga is correct because the polygon has six sides.
Taiga is correct because the sides have different lengths.
Taiga is not correct because the polygon is a hexagon.
Taiga is not correct because he drew the polygon incorrectly.

11. Albert has 12 more 10 cent coins than 20-cent
coins. The total value of all his coins is $5.40. Find
the total number of coins he has.
Step-by-step explanation:
Let x be the number of 10 cent coins
Let y be the number of 20 cent coins
given
[tex]x = y + 12 \\ x - y = 12[/tex]
as equation 1
and
[tex]0.1x + 0.2y = 5.4[/tex]
as equation 2.
Now we will use elimination method to solve simultaneous equations.
Now we multiply equation 1 by 0.2 to eliminate y and solve for x first.
[tex]0.2 \times x - 0.2 \times y = 12 \times 0.2 \\ 0.2x - 0.2y = 2.4[/tex]
Let this new equation be equation 3.
Now use equation 2 + equation 3.
[tex]0.1x + 0.2x + (0.2y + ( - 0.2y)) = 5.4 + 2.4 \\ 0.3x = 7.8 \\ x = 7.8 \div 0.3 \\ = 26[/tex]
Substitute x into equation 1,
[tex]x = y + 12 \\ y + 12 = x \\ y = x - 12 \\ = 26 - 12 \\ = 14[/tex]
Therefore total number of coins = x + y = 26 + 14 = 40
Answer:
in total he has 62 cents

What is the equation of the line that is parallel to the line y = 3x - 4 and passes
through the point (4, -2)?
A. Y= 3x + 2
B. y= 3x - 14
O C. --}x
D. y = 3x + 14
Answer:
B. y = 3x - 14
Step-by-step explanation:
Since the line is parallel, your slope will be 3. You're given a point, so you can use point-slope form to find the equation. Point-slope form is:
y - y1 = m(x - x1) where (x1, y1) is the point that they gave you and m is the slope. So:
y - (-2) = 3(x - 4) --> Start to simplify this by changing - (-2) to +2 and distributing the 3 to (x - 4).
y + 2 = 3x - 12 --> Subtract 2 from both sides.
y = 3x - 14

Answer:
The area of the triangular case = 61.2 square inches
Step-by-step explanation:
P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = [tex]14\frac{2}{5}in[/tex]
Height of triangle = 8.5 in
We know that,
Area of triangle = [tex]\frac{1}{2}*Base*Height[/tex]
= [tex]\frac{1}{2}*8.5*14\frac{2}{5}[/tex]
= [tex]\frac{1}{2}*8.5*14.4[/tex]
= [tex]\frac{1}{2}*122.4[/tex]
= 61.2
∴ we get
The area of the triangular case = 61.2 square inches

Answer:
m= 2 43/63
Step-by-step explanation:
steps
6 1/9 = 3 3/7 + m
convert mixed numbers into improper fractions 6 1/9 = 55/9
55/9 = 3 3/7 + m
convert mixed numbers into improper fractions 3 3/7 = 24/7
55/9 = 24/7 + m
switch sides
24/7 + m = 55/9
subtract 24/7 from both sides
24/7 + m - 24/7 = 55/9 - 24/7
simplify
m = 169/63
convert improper fraction to mixed number
169/63 = 2 43/63
so your final answer is 2 43/63

The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2.5
Step-by-step explanation:
2(17y + 6) + 2(10y - 9) = 129
34y + 12 + 20y - 18 = 129
54y - 6 = 129
54y = 135
y = 2.5
