Leila took a nap. She fell asleep at 11:40 AM and she woke up at 2: 13 PM. How long did she sleep?

The inequality which can be used to determine x is equal to 78.20x ≤ 304.98 , and the number of outfits Madeline can purchase while staying within her budget is 3  .

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that Total money Madeline can spend = $680

Price of the cycle = $318.67

Price of 2 pair of reflectors = 2x 12.89 = $25.78

Price of a pair of bike gloves = $30.57

It can calculated as Money left with Madeline = (Total money Madeline has ) - price of the cycle - price of 2 pair of reflectors - price of a pair of bike gloves

Thus Money left with Madeline = 680 - 318.67 - 25.78 - 30.57

                                          = $304.98

Consider Madeline purchase x number of  biking outfits

The price of each biking outfit = $78.20

The price of x biking outfit = 78.20x

Since Madeline has only $304.98 She can only use not more than $304.98.

The inequality becomes

78.20x ≤ 304.98

Solving for x we get;

x ≤ 304.98/78.20

x ≤ 3.9

Hence , x ≤ 3.

Using the formula of probability without replacement, the probability of selecting 2 greens without replacement is 1/12

When things are taken out of a set or collection as they are chosen, the probability that a certain occurrence will take place is known as probability without replacement. In probability with replacement, the elements are altered after each choice is made, but the set is left alone.

We use the following formula to determine probability without replacement:

P(Event) = Number of positive results / Number of potential results

Where the total number of items in the set represents the number of outcomes that are feasible, and the number of positive outcomes is the number of items that meet the event requirements.

Total number of possible outcomes = 3 + 3 + 3 = 9

A statement which correctly describes the comparison between the shapes of the box plots include the following: A. The Bulldogs' distribution is symmetric, but the Wolverines' distribution is negatively skewed.

In Mathematics, skewness can be defined as a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.

By critically observing the box plot (box-and-whisker plot) which represent basketball scores for the Bulldogs basketball team has a median of 80 (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

On the other hand (conversely), the box plot (box-and-whisker plot) for the Wolverines basketball team shows that the median is more closer to the third quartile (upper quartile) and the whisker to the right of the box plot is longer, which ultimately implies that Wolverines' distribution is negatively skewed.

The required equation is

Percent Remaining = (100 grams) * (0.5)^(12 weeks / 6 weeks)

Generally, The equation that determines the percent of an initial amount of a radioisotope remaining after t weeks is:

Percent Remaining = (Initial Amount) * (0.5)^(t/Half-Life)

In this equation, "Initial Amount" is the amount of the radioisotope at the start of the time period being considered (for example, at the start of the autopsy).

"Half-Life" is the length of time it takes for half of the radioisotope to decay.

"t" is the length of time that has passed since the start of the time period being considered.

The term (0.5)^(t/Half-Life) represents the fraction of the initial amount of the radioisotope that remains after t weeks.  This term is called the decay constant.

It is raised to the power of t/Half-Life because the decay constant is the fraction of the radioisotope that remains after one half-life.

If t is equal to the half-life, then the decay constant is raised to the power of 1, which is equal to itself.

If t is twice the half-life, then the decay constant is raised to the power of 2, which means that only a quarter of the initial amount remains.

For the radioisotope Xenos-6, the half-life is 6 weeks. Using the equation above, we can determine the percent of the initial amount of Xenos-6 remaining after any number of weeks by plugging in the appropriate values.

For example, if we have an initial amount of 100 grams of Xenos-6 and we want to know the percent remaining after 12 weeks, we would plug in the values like this:

Percent Remaining = (100 grams) * (0.5)^(12 weeks / 6 weeks)

This would give us a result of 25%, which means that 25 grams of Xenos-6 would remain after 12 weeks.

Answer:

I'm not really sure if this is the right answer because I'm in high school and your in collage so here's what I can do:

Step-by-step explanation:

Let X be the number of pounds of peanuts selling for 85 cents per pound and Y be the number of pounds of peanuts selling for 98 cents per pound.

We can set up the following system of equations to represent this situation:

X * 0.85 + Y * 0.98 = 0.90 * (X + Y)

X + Y = 40

The first equation represents the total cost of the blend, and the second equation represents the total number of pounds of peanuts.

To solve this system of equations, we can use a method such as graphing, substitution, or elimination.

Using the substitution method, we can solve for one variable in terms of the other and substitute it into the other equation. For example, we can solve the first equation for X:

X = (0.90 * (X + Y) - Y * 0.98) / 0.85

Then, we can substitute this expression for X into the second equation:

(0.90 * (X + Y) - Y * 0.98) / 0.85 + Y = 40

Solving this equation for Y gives us the number of pounds of peanuts selling for 98 cents per pound:

Y = (40 * 0.85 - 0.90 * X) / (0.10 - 0.98)

To find the value of X, we can substitute this expression for Y into the first equation and solve for X:

X * 0.85 + (40 * 0.85 - 0.90 * X) / (0.10 - 0.98) * 0.98 = 0.90 * (X + (40 * 0.85 - 0.90 * X) / (0.10 - 0.98))

Solving this equation for X gives us the number of pounds of peanuts selling for 85 cents per pound:

X = 18.75

Therefore, 18.75 pounds of peanuts selling for 85 cents per pound must be mixed with 40 pounds of peanuts selling for 98 cents per pound to produce a blend selling for 90 cents per pound.
