What Is $12 for 5 boxes of cereal as a unit rate

The smallest integer that can possibly be the sum of an infinite geometric series whose first term is 9 is not possible.

An infinite geometric series is a series that continues indefinitely, where each term is found by multiplying the previous term by a constant ratio.

To determine the convergence limit, we must first determine if the series converges. The series converges if the absolute value of the common ratio is less than 1. If the series converges, the sum can be found using the formula:

S = a / (1 - r)

Where S is the sum, a is the first term of the series (9 in this case), and r is the common ratio. For the sum to be an integer, the denominator (1 - r) must equal 1, which means r must equal 0.

This is not possible, as the absolute value of the common ratio must be less than 1 for the series to converge.

Therefore, the sum of the series cannot be an integer.

The probability that the system will function tomorrow is 0.2495 or 24.95%.

To find the probability that the system will function tomorrow, we need to find the probability that at least 4 out of the 6 components will function.

On a rainy day, the probability of 4 components functioning is given by:

P(rainy day and 4 components functioning) = C(6, 4) × (0.5)⁴ × (0.5)² = 15 × 0.0625 × 0.25 = 0.2344

On a non-rainy day, the probability of 4 components functioning is given by:

P(non-rainy day and 4 components functioning) = C(6, 4) × (0.8)⁴ × (0.2)² = 15 × 0.4096 × 0.04 = 0.2534

Now we can find the overall probability of the system functioning tomorrow by using the law of total probability:

P(system functioning tomorrow) = P(rainy day and 4 components functioning) × P(rain) + P(non-rainy day and 4 components functioning) × P(non-rain)

= 0.2344 × 0.20 + 0.2534 × 0.80

= 0.0468 + 0.2027

= 0.2495

A frequency distribution in which high scores are most frequent is said to be positively skewed or right-skewed.

In statistics, skewness refers to the asymmetry of a probability distribution. A frequency distribution is said to be positively skewed or right-skewed if the majority of the data is concentrated on the right side of the distribution, while a few high values are outliers on the right tail. The frequency distribution will look like a graph that is shifted to the right with a longer tail on the right side.

Positive skewness means that the mean (average) of the data will be higher than the median (middle value). The median is a more robust measure of central tendency than the mean in a positively skewed distribution, because it is not influenced by the outliers on the right tail.

Complete question -

less than 85 milligrams per liter.

To find the probability that a water specimen has an alkalinity level of fewer than 85 milligrams per liter, we can use the standard normal distribution and convert the value of 85 milligrams per liter to a standard score (z-score). The z-score can be calculated using the formula:

z = (x - mean) / standard deviation

Where x is the value of interest (85 milligrams per liter), mean is the mean of the distribution (80 milligrams per liter), and the standard deviation is the standard deviation of the distribution (4.2 milligrams per liter).

Plugging in the values, we get:

z = (85 - 80) / 4.2 = 1.19

Next, we can use a standard normal table or calculator to find the probability of getting a value less than the z-score of 1.19. This probability is approximately 0.8707, so there is about an 87.07% chance that a water specimen collected from the river has an alkalinity level of fewer than 85 milligrams per liter.

Answer: The answer is 34 degrees.

Step-by-step explanation: Angle 1 and angle 5 are the same.

The probability of a student completing the final examination in less than 65 minutes is 13.45%.

The time it takes to complete a final examination in a particular college course is normally distributed with a mean of 77 minutes and a standard deviation of 12 minutes. This can be expressed mathematically as X~N(77, 12).

The probability of a student completing the final examination in less than 65 minutes can be calculated by using the Z-score formula:

Z = (x - μ) / σ

Where x = 65 minutes, μ = 77 minutes, and σ = 12 minutes.

Plugging these values into the formula, we get:

Z = (65 - 77) / 12 = -1.17

Using a Z-score table, we can find the probability of a student completing the final examination in less than 65 minutes, which is equal to 0.1345, or 13.45%. Therefore, the probability of a student completing the final examination in less than 65 minutes is 13.45%.

1) To determine that both shapes are similar, all we need to divide the side lengths of D by two. This gives us:

Breath  - 6/2 = 3

Length - 14/ 7 = 7

Since the Breadth of F is 3ft and it's length 7ft, it means D and F are similar to the ratio of 2:1.

2) If the above logic is applied to A and B, we would see that the side lengths of both shapes have different ratios.

If a bloodstain is 1.5cm wide and 30cm long, then the angle of impact is 30°.

In forensic science, the angle of impact is the angle at which a blood droplet strikes a surface. It has a range of 0 to 90 degrees and is, by definition, an acute (or right) angle.

Police can partially reconstruct a crime scene by connecting the "strings" that lead from the spatter to an origin area and knowing the angle of contact.

If a bloodstain has a tail or pattern, the angle of impact can be used to forecast how the subsequent bloodstain would look.

So, bloodstain pattern analysis examines the patterns of bloodstains found at crime scenes in an effort to piece together the sequence of events that led to the bloodshed.

Mathematically, we will have:

The angle of impact = sin⁻¹ (wide stain/length stain)

The angle of impact = sin⁻¹ (1.5/3.0)

The angle of impact = 30°

Therefore, if a bloodstain is 1.5cm wide and 30cm long, then the angle of impact is 30°.

The maximum area of the rectangle is 12100 square feet  when the owner of a used tire store wants to construct a fence to enclose a rectangular outdoor storage area.

To find the dimensions of the outdoor storage area with the most area, we need to maximize the product of the length and width of the rectangle.

Let's assume that the length of the rectangle is x and the width is y.

Since one side of the store, which is 240 feet long, will be used as one of the sides of the rectangle, the total length of the remaining three sides is 460 feet.

So, the sum of the lengths of the other two sides must be

[tex]460 - x = 460 - 240 = 220 feet.\\[/tex]

Since the width and length of the rectangle are related by [tex]y = 220 - x[/tex] , we can substitute this into the expression for the area, which is given by [tex]A = x * y = x * (220 - x)[/tex]

To find the maximum value of A, we can differentiate this expression with respect to x and set the derivative equal to zero, which will give us the value of x that maximizes the area.

The critical points occur at x = 0 and x = 220/2 = 110.

Since the area is a continuous function, it follows that the area will be at a maximum at the larger of the two critical points, which is x = 110.

Thus, the length and width of the rectangle with the largest area are 110 feet and 110 feet, respectively.
