Three angles are given to us and we all know that the sum of four sides of quadrilateral is 360⁰
so
133⁰ + 147⁰ + 47⁰ + x = 360⁰
x = 380⁰ - 367⁰

What is the smallest sample size the company can take to pass the large counts condition?
Answers
100 people cuz 90% of 100 is 90
5 % is 5
So its easier to interpret
Answer:
The smallest sample size the company can take and still pass the large counts condition is 100 total customers.
Step-by-step explanation:
The large counts condition says that all expected counts need to be at least 5. The company needs to sample enough customers so that they expect each mode of payment to appear at least 5 times. Since the distribution they expects is uneven, we should look at the mode of payment that has the lowest expected percentage.
The lowest expected percentage is 5%, percent, which is the percentage of both cash and payment via smartphone, We need to pick a sample so 5%, percent of its size equals at least 5.
0.05x ≥5
x ≥100
So, the company needs to sample at least 100 customers.

Mr. Smart wants to set up an annual scholarship by donating $50,000 to the scholarship fund of his university. If the first payment is to be made in 5 years and interest is 4% compounded annually, what is the amount of the annual scholarship?
Answers
Answer:
$60,832.65
Step-by-step explanation:
The formula for calculating the amount is expressed as;
A = P(1+r)^t
P is the principal = $50,000
r is the rate = 4% = 0.04
Time = 5 years
substitute;
A = 50000(1+0.04)^5
A = 50000(1.04)^5
A = 50,000(1.2167)
A = 60,832.65
Hence the amount of the annual scholarship is $60,832.65

Answer:
488 cm² (Option B)
Step-by-step explanation:
The figure consists of a rectangle & a right angled triangle. So,
Area of the complex figure = Area of rectangle + Area of the triangle
1) Length of the rectangle = 22 cm
Width of the rectangle = 17 cm
Area of rectangle = 22 × 17 = 374 cm²
2) Length of perpendicular of the triangle = 22 - 10 = 12 cm
Length of base of triangle = 19 cm
Area of a triangle = [tex]\frac{1}{2} \times 12 \times 19 = 114 cm^2[/tex]
∴ AREA OF THE FIGURE = 378 + 114 = 488 cm²

Answers
Answer: (4,3)
Step-by-step explanation:
We can rearrange the first equation to get [tex]3x-9=y[/tex].
Thus, we can conclude that:
3x - 9 = -2x + 11 5x - 9 = 11 [add 2x to both sides]5x = 20 [add 9 to both sides]x = 4 [divide both sides by 5]Thus, if x = 4, y=3(4)-9=3.
So, they graphs intersect at (4,3).

You sell instruments at a Caribbean music festival. You earn $326 by selling 12 sets of maracas, 6 sets of claves, and x djembe drums. Find the number of djembe drums you sold
Answers
First, it is important to know the prices of each of the instruments in order to determine the number of djembe drums you had sold. Since it is not given here. I will give a general equation where you just substitute the prices. It would be as follows:
326 = 12x + 6(y) + (xx)z
where x is the price for a set of maracas
y is the price for a set of claves
xx is number of djembe drums sold
z is the prices for each djembe drum
Hope this helps. Have a nice da
Answer:
(14*12)+(5*6)+16x
Step-by-step explanation:
First, you get the price of every instrument.
(Shown in the picture)
Maracas: $14
Claves: $5
Djembe Drums: $16
Then multiply the price to how many instruments you sold.
14*12 (Maracas)
5*6 (Claves)
You don't know what how many djembe drums you sold, so put an x right next to 16.
To get the total of $326 in that equation, you do: (14*12)+(5*6)+16x.
I hope it helps.

Gia receives an allowance of $2 a week and already has $20 in savings. Michael receives an allowance of $3 a week and already has $5 in savings. Gia and Michael both save their entire allowance. After how many weeks, will Gia and Michael have the same amount in savings? How much money will they have?
Answers
Answer:
After 15 weeks, Gia and Micheal will both have $50 in savings.
Step-by-step explanation:
For Gia:
We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.
Gia receives $2 a week and therefore in 15 weeks she will have $50.
= 2x15 = $30
= 30+20 = $50
For Micheal:
We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.
Micheal receives $3 a week and therefore in 15 weeks he will receive $50
= 3x15 = $45
= 5+45 = $50

Mark works at the mall 3 hours on Friday and 5 hours on Saturday. He gets a
weekly allowance of $25 from his parent. If he made $85 this weekend, how
much does he get paid an hour at his job?
Answers
Answer:
$7.50
Step-by-step explanation:
3 hours + 5 hours = 8 hours
8 hours = $85 (total) - $25 (allowance)
8 hours = $60 (money earned from work)
1 hour = $60 ÷ 8 (hours he worked)
1 hour = $7.50
