The requried percentage change in crimes from years 1 to 5 is given as    60.86%.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
From the table.

Crime in year 1 = 23
Crime in year 5 = 9

Percentage change = 23 - 9 / 23 ×100%
                              = 60.86%

Thus, the requried percentage change in crimes from years 1 to 5 is given as 60.86%.

The smallest positive integer that is neither prime nor square and that has no prime factor less than 50 is 3137.

This can be determined by using the prime factorization method. Prime factorization is a process of breaking down a number into its prime factors. The prime factors of a number are the factors that are only divisible by one and itself. For 3137, the prime factors are 3, 7, 17 and 37 since these are the only prime numbers that can divide 3137 evenly. Since none of the prime factors are less than 50, 3137 is the smallest positive integer that is neither prime nor square and that has no prime factor less than 50.

Answer:

  (c)  C(p) =.15 (p- 50) + 8.95

Step-by-step explanation:

You want an equation for the cost of prints that are $0.15 for each print over 50 plus an additional $8.95.

The number of prints over 50 will be (p -50). At $0.15 for each of these, their cost will be ...

  0.15(p -50)

When the $8.95 charge is added, the total comes to ...

  c(p) = 0.15(p -50) +8.95

Additional comment

The problem statement asks for the function to be written C(p). The answer choices use c(p) with the variable x in the equation where p should be. In effect, none of the answer choices is correct.

The code that creates a function that will return the product of two integers is given below:

In mathematics, whole numbers and negative numbers are grouped together as integers. Integers, like whole numbers, do not include the fractional portion.

Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all mathematical operations, including addition, subtraction, multiplication, and division.

The value of k in the equations is 2/3

From the question, we have the following parameters that can be used in our computation:

y = 9kx - 1

kx + 4y = 12

This can be expressed as

y = 9kx - 1

y = -kx/4 + 3

The slopes of perpendicular lines are opposite reciprocal

This means that

9k * -k/4 = -1

The Typewriters should be guaranteed for 7.72 months, which would give a 5% chance of requiring a major repair before the end of the guarantee period.

Typewriter repair times have a normal distribution, with a mean of 11 months and a standard deviation of 2 months. To find the warranty period at which only her 5% of typewriters fail before the warranty expires, we need to find the corresponding z-score and solve it after the warranty period.

Using the standard normal distribution table, we find that the Z-score corresponding to a cumulative probability of 0.95 is approximately 1.64.

This means that 95% of typewriters will need major repairs after 11 + 1.64 * 2 = 14.28 months.

To ensure that only 5% of typewriters fail before the warranty expires, the warranty period should be set to 11 - 1.64 * 2 = 7.

Answer: x = -2

Step-by-step explanation:

The values of x and y are 15 and 7 respectively.

Similar triangles are those triangles which has the same shape but different size.

The length of sides are proportional in similar triangles.

Two sails are similar triangles.

So the angles of two sails are equal and the corresponding sides are proportional.

We can write the relation as,

x / 30 = x- 2 / 26 = y + 9 / 5y - 3

Consider x / 30 = x- 2 / 26.

Cross multiplying,

26x = 30(x - 2)

26x = 30x - 60

-4x = -60

x = 15

Consider x / 30 = y + 9 / 5y - 3.

Substituting x = 15,

15 / 30 = y + 9 / 5y - 3

1 / 2 = y + 9 / 5y - 3

Cross multiplying,

5y - 3 = 2y + 18

3y = 21

y = 7

Unknown sides are,

x = 15 feet

x - 2 = 13 feet

y + 9 = 16 feet

5y - 3 = 32 feet

Hence the value of x is 15 and the value of y is 7.

Null hypothesis: proportion of errors = 46%. Alternative hypothesis: proportion of errors ≠ 46%. Hypothesis test done using sample proportion and significance level of 0.05.

What is null hypothesis ?

The null hypothesis is a characteristic arithmetic theory suggesting that no statistical relationship and significance exists in a set of given, single, observed variables between two sets of observed data and measured phenomena.

To test if there is sufficient evidence to refute the hospital director's claim, we would perform a hypothesis test. The test statistic in this case would be the sample proportion of lab reports with errors (95 errors out of 250 total lab reports), and we would compare this to the null hypothesis value of 46%. The p-value for this test represents the probability of observing a sample proportion as extreme or more extreme than the observed proportion, given that the null hypothesis is true.

If the p-value is less than the significance level of 0.05, we would reject the null hypothesis, which means we have sufficient evidence to conclude that the proportion of lab reports with errors is not equal to 46%. On the other hand, if the p-value is greater than or equal to the significance level of 0.05, we would fail to reject the null hypothesis, which means we do not have sufficient evidence to conclude that the proportion of lab reports with errors is different from 46%.

Null hypothesis: proportion of errors = 46%. Alternative hypothesis: proportion of errors ≠ 46%. Hypothesis test done using sample proportion and significance level of 0.05.

In the number 652.12, the value of the 2 in the hundredths place is much smaller than the value of the 2 in the ones place. In this number, the 2 in the hundredths place represents 0.02, which is two hundredths of a unit. On the other hand, the 2 in the ones place represents 2 units.

To understand the difference in value, consider that the decimal point separates the number into its integer part (to the left of the decimal point) and its fractional part (to the right of the decimal point). The place value of each digit depends on its position relative to the decimal point. The rightmost digit is the ones place, the digit to its left is the tens place, and so on. The place value of the digits to the right of the decimal point is determined by powers of 10 that are negative, starting from -1 for the hundredths place, -2 for the thousandths place, and so on.

Therefore, in the number 652.12, the 2 in the hundredths place has a place value of 0.02 and the 2 in the ones place has a place value of 2. This means that the 2 in the ones place is 100 times greater in value than the 2 in the hundredths place.

When the sample sizes are large, a chi-squared test (also known as a chi-square or 2 test) is a statistical hypothesis test used in the study of contingency tables. To put it another way, the main purpose of this test is to determine if two categorical factors (two dimensions of the contingency table) have independent effects on the test statistic (values within the table).

The test, specifically Pearson's chi-squared test and its variations, is valid if the test statistic is chi-squared distributed under the null hypothesis. If there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table, it can be determined using Pearson's chi-squared test.

The faster train would be travelling at 120 mph.

Let's give the slower train's speed the designation of x mph. The speed of the speedier train would then be x + 10 mph.

The 4.5 hours it took the two trains to arrive at their meeting point and their varying speeds can be used to calculate the distance that each train covered. The relative speed is equal to the product of the velocities of the two trains,

Therefore (x) + (x + 10) = 2x + 10 mph.

Distance = rate x time gives the distance covered by each train.

The slower train's route can be expressed as follows:

x * 4.5 hours = 495 miles.

Additionally, the quicker train covered 495 miles in (x + 10) * 4.5 hours.

We can now use these two equations to solve for x:
