Step-by-step explanation: I has a negative slope, which means that its line is shaped like a backslash. This graph is shaped like a forward slash, so it cannot be that one. III is a quadratic equation in factored form. The graph for a quadratic equation is shaped like a U or an upside down U, so it cannot be that one either.

What is the probability that a five-card poker hand contains exactly one ace?.

Answers

The probability of selecting exactly one ace is its likelihood

The probability that a five-card poker hand contains exactly one ace is 29.95%

How to determine the probability?

There are 4 aces in a standard deck of 52 cards.

The probability of selecting an ace would be:

p = 4/52

Also, there are 48 non-ace cards in the standard deck

So, the probability of selecting a non-ace after an ace has been selected is:

p = 48/51

The probability of selecting a non-ace up to the fifth selection are:

After two cards have been selected is: 47/50.After three cards have been selected is: 46/49.After four cards have been selected is: 45/48.

The required probability is then calculated as:

P(1 Ace) = n * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)

Where n is the number of cards i.e. 5

So, we have:

P(1 Ace) = 5 * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)

Evaluate

P(1 Ace) = 0.2995

Express as percentage

P(1 Ace) = 29.95%

Hence, the probability that a five-card poker hand contains exactly one ace is 29.95%

Carla served her mango pie on a 14 inches diameter dish. She wanted to tie a ribbon around the dish to make it a little more attractive. How long does the ribbon need to be in order to fit around the dish?

Answers

By finding the circumference of the plate, we conclude that the ribbon must be 43.96 in long.

How long does the ribbon need to be?

Remember that for a circle of radius R, the circumference is:

C = 2*pi*R

In this case, the ribbon must be equally long to the circumference of the plate. We know that the diameter of the plate is 14 inches, and the radius is half of that, then we get:

R = 14in/2 = 7in

Replacing that on the circumference equation we get:

C = 2*3.14*7in = 43.96 in

The ribbon must be 43.96 in long.

Sydney took a trip to a relatives house for Thanksgiving. She drove 65 miles per hour for 1. 5 miles and 55 miles per hour for 3. 5 hours. What was the total distance in miles that she traveled duribg this time?

Answers

The total distance in miles that she traveled duribg this time is 17.21miles

Distance and speed

Speed is defined as the rate of change of distance. Mathematically speed is expressed as:

Speed = Distance/Time

For the second trip

Speed = 55mph
Time = 3.5hours

Distance = 55/3.5

Distance = 15.71 miles

Total distance travelled = 1.5 miles + 15.71miles

Total distance travelled = 17.21miles

Hence the total distance in miles that she traveled duribg this time is 17.21miles

The cost of renting a moving truck is given by C = 40 + 0.99m , where C is the total cost in dollars and m is the number of miles driven. What does the 40 in the equation represent?

Answers

The 40 represents a base cost. The company charges $40 for just using their equipment.

The 40 in the equation C = 40 + 0.99m represents a fixed cost that is independent of the number of miles driven (m).

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

This fixed cost is a base fee that the rental company charges for the rental of the moving truck, regardless of how many miles the truck is driven.

In this equation, the 40 is a constant term that adds to the cost of the rental, and it represents the cost of the truck rental without taking into account the distance driven.

The 0.99m term represents the additional cost per mile driven, and it increases with the number of miles driven.
