At a restaurant, 30% of customers donate to charity in exchange for a coupon. Estimate the probability that it will take at least four customers to find one who donates.

Answers

Answer 1

Answer:

75.99%

Step-by-step explanation:

To calculate this, we can use complements. We can find, instead the probability that at least one will donate, the probability that not none of them will donate.

First, we can find the probability that none will donate, which will be (70%)^4, since the chance each will not donate is the same. From this we get 24.01%.

To find the probability that at least one donates, we do the complement:

100%-24.01%=75.99%

2. Given < MCP = 65°, find the measurement of arc MP , arc MRP and < MRP.​

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

We know that the Angle subtended by an arc on centre of the circle is double as that of Angle subtended by the same arc on the circumference (boundary) of the circle

So,

[tex] \sf \angle MCP = 2\angle MRP[/tex]

[tex] \sf65 \degree = 2 \angle MRP[/tex]

[tex] \sf\angle MRP = 65 \degree \div 2[/tex]

[tex] \sf\angle MRP = 32.5 \degree[/tex]

Answer:

arc MP = 65°arc MRP = 295°angle MRP = 32.5°

Step-by-step explanation:

The measure of an arc is the same as the measure of the central angle it subtends.

  arc MP = ∠MCP = 65°

Long arc MRP is the difference between arc MP and the full circle:

  arc MRP = 360° -65° = 295°

Inscribed angle MRP is half the measure of the arc it subtends:

  ∠MRP = (arc MP)/2 = 65°/2 = 32.5°

Which statement is true about the slope of the line and what it means in this
situation?
The slope of the line is 1. This means that Jan runs 1 lap every minute.
The slope of the line is 2. This means that Jan runs 2 laps every minute.
I
The slope of the line is 2. This means that Jan runs 1 lap every 2 minutes.
The slope of the line is 4. This means that Jan runs 4 laps every minute.

Answers

Answer:

B. The slope of the line is 2. This means that Jan runs 2 laps every minute.

Step-by-step explanation:

This is a proportional relationship as the line passes through the origin.

Therefore you can use one point to determine the slope, (2, 4):

m = y/x = 4/2 = 2

The slope is 2. It is a 2 laps per minute.

Correct answer choice is B

(0,0)(2,4)

Slope

m=4-0/2-0m=4/2 m=2

Rate is 2 laps every minute

Step-by-step explanation:

The area of the rhombus is 12 cm².

Given that, a rhombus has a side length of 6 centimetres, and a height of 2 centimetres.

We need to find the area of the rhombus, in centimetres.

What is the area of the rhombus?

The formula for the area of the rhombus when base and height are known.

The rhombus is a parallelogram. We know that the area of a parallelogram is given by multiplying base and height sq units. The same is applied to the rhombus as well. Area of a rhombus = Base × Height sq units.

Now, the area of a rhombus= 6×2=12 cm²

Therefore, the area of the rhombus is 12 cm².

8 3/42, 34 1/2, 11 1/49 3/4, 16 1/4Y/B = 2/3

Step-by-step explanation:

a)

The first line is simply the sum of the two given numbers.

  3 1/2 +5 1/4 = (3+5) +(2/4+1/4) = 8 3/4

__

To find values on the remaining lines, it is convenient to find the ratios of the numbers involved. The ratio of yellow to blue is ...

  Y/B = (3 1/2)/(5 1/4) = (7/2)/(21/4) = (7/2)(4/21) = 2/3

Then ...

  Y : B : total = 2 : 3 : 5

This tells you the numbers on the second line are ...

  Y = 2; B = 3

__

The value for B on the third line is the basic ratio number multiplied by (6 3/4)/3 = 2 1/4. Then the other two numbers are ...

  Y = 2(2 1/4) = 4 1/2

  total = 5(2 1/4) = 11 1/4

__

The value for Y on the fourth line is the basic ratio number multiplied by (6 1/2)/2 = 3 1/4. Then the other two numbers are ...

  B = 3(3 1/4) = 9 3/4

  total = 5(3 1/4) = 16 1/4

_____

b)

The equation is the one we used to find the values on the second line:

  Y/B = 2/3

What is the smallest two-digit integer $n$ such that switching its digits and then adding 3 results in $2n$

Answers

We can write

n = 10a + b

where a and b belong to {1, 2, 3, …, 9}.

Swapping the digits produces a new number

n' = 10b + a

and adding 3 to this number makes up 2n,

n' + 3 = 2n

or

(10b + a) + 3 = 2 (10a + b)

so that

19a - 8b = 3

Since we want n to be the smallest possible 2-digit number that meets the criteria, let's start with a = 1. Then solving for b, we find

19 - 8b = 3

16 = 8b

b = 2

So, the number we're looking for is n = 12.

Just to confirm, swapping the digits gives 21, and 21 + 3 = 24 = 2•12.
