Answer:

B 22.98

Step-by-step explanation:

divided 11.49 by 3, you get 3.83, then multiply it by 6. thats your answer

Answer:

B: $22.98

Step-by-step explanation:

The first thing we need to do for this question is find a pattern. Find a pattern between the prices of 3 pizzas, 4 pizzas, and 5 pizzas. Once we have this pattern, we can solve for x.

To find the pattern, we must first subtract the price of 4 pizzas from the price of 3 pizzas. This difference is 3.83, so we know the price went up $3.83. Next, subtract the price of 5 pizzas from the price of 4 pizzas. This is also 3.83, so we know that for every extra pizza added, the price goes up $3.83.

Now that we have our pattern, we can solve for x. Because the price goes up $3.83 for every extra pizza added, we can add $3.83 to the price of 5 pizzas. This will give us $22.98. We now know the value of x and the price of 6 pizzas.

I hope this helps. Please let me know if you need any more help. Have a great day and good luck!

Answer:

$18.28

Step-by-step explanation:

To get the answer all I did was take 7.5% of 17 which is 1.275

I then rounded 1.275 to 1.28. When you round up the number after the 7 has to be 5 or above. Seeing as the number was 5 we rounded it up to 1.28.

Then I took $17+$1.28= $18.28.

I hope this helps!!!

The proof is shown below:

The tangent is defined as a line touching circles or an ellipse at only one point.

As, tangent line is perpendicular to radius of the circle.

So,

AR ⊥ RS

BS ⊥ RS

Thus, AR and BS ⊥ to same line RS.

Now, either AR or BS are in same line or parallel.

since, they are the radius of different circles.

Hence, AR ║BS.

Step-by-step explanation:

Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)

Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)

Is there a photo the problem or is that just it?

Answer:

The answer is the last two.

Step-by-step explanation:

Answer:

Because two adjacent angles from a right angle sums up to 90° and the larger angle is 3 times the measurement of the smaller angle, the equation would be 3a + a = 90° (A will be the substituting variable for the smaller angle). Add the like terms to get 4a=90. Divide 4 on both sides to get 22.5°. Substitute 22.5 into the variable, a, to get 67.5. This means that the larger angle would be 67.5° and the smaller angle would be 22.5°.

Answer:

Option C will be your answer

Step-by-step explanation:

Angle C will be equal to 52 by vertical angle theorem

hope it helps you

have a great day !!

Angle c is the vertical opposite angle with 52° so it will have a measure of 52° thus option (C) is correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Two opposite angle made by two intersecting lines is said to be vertically opposite angle so the angle opposite to 52° is c so, ∠c = 52°.

Hence " Angle c has a measure of 52° since it is the vertical opposite angle with 52°".

The missing probability will be P(A) = 3/25. The correct option is C.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain. Probability is used in mathematics, statistics, and many other fields to quantify uncertain or random events.

To find the missing probability P(A), we can use the formula for the probability of the intersection of two events:

P(A and B) = P(A) * P(B|A)

Where P(B|A) is the conditional probability of B given A.

Rearranging this formula, we get:

P(A) = P(A and B) / P(B|A)

To find P(B|A), we can use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

Substituting this into the first formula, we get:

P(A) = P(A and B) / (P(A and B) / P(A))

Simplifying, we get:

P(A) = P(A and B) / P(B)

Substituting the given values, we get:

P(A) = (6/25) / (2/5)

Simplifying, we get:

P(A) = (6/25) x (5/2)

P(A) = 3/25

Therefore, the missing probability is P(A) = 3/25.

Step-by-step explanation:

Answer:

Expected value for 4 tickets = $ -7.6

Step-by-step explanation:

Given - A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each.

To find - Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.

Proof -

Given that,

A lottery offers

one $ 900 prize

one $ 600 prize

three $ 400 prizes

Four $ 100 prizes

And

One thousand tickets are sold at $ 5 each

Now,

If the person bought 1000 tickets then the prize he gets is

= 900 + 600 + 3×400 + 4×100

= 900 + 600 + 1200 + 400

= $3100

And

The cost of 1000 tickets = 5×1000 = $ 5000

Now,

Price 1 ticket = [tex]\frac{3100}{1000}[/tex] = $ 3.1

⇒Expectation of 1 ticket = $ 3.1 - 5 = $ -1.9      (Here $5 is price of 1 ticket)

⇒Expected value for 4 tickets = $ 4× -1.9 = $ -7.6

⇒Expected value for 4 tickets = $ -7.6

Answer:

3,4 is the correct answer for this question
