Write 735 as the product of its prime factor.

Answer: x = -2

Step-by-step explanation:

Since both equations are in the y-slope form,

we can use substitution for y in finding x.

Hence,

4x=x-6

4x-x=x-x-6

Subtract x from both sides to get x on one side and integer on one side.

(A). The probability distribution of X is approximately normal because the sample size is large enough (n = 50) and the population proportion (p = 0.78) is not too close to 0 or 1.

(B) The mean of the approximately normal distribution is μ = np = 50 x 0.78 = 39, and the standard deviation is σ = sqrt(np(1-p)) = sqrt(50 x 0.78 x 0.22) = 3.22.

(C) To calculate the probability that 35 or fewer individuals need to standardize the value of X using the formula z = (X - μ) / σ. Then, z = (35 - 39) / 3.22 = -1.24 in the standard normal distribution table or using a calculator. The probability is approximately 0.1093 or 10.93%.

(D). The null hypothesis is H0: p = 0.78, and the alternative hypothesis is Ha: p < 0.78. The test statistic is z = (35/50 - 0.78) / sqrt(0.78 x 0.22 / 50) = -1.97, which has a p-value of 0.0244 or 2.44%.

Probability is a branch of mathematics that deals with the study of random events. It is the measure of the likelihood of an event occurring, expressed as a number between 0 and 1. An event with probability 0 means it will never occur, while an event with probability 1 means it will always occur.

The calculation of probability involves analyzing the possible outcomes of an event and assigning a probability to each outcome based on its likelihood of occurring. The probability of an event is determined by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in various fields, such as statistics, finance, engineering, and science, to make predictions and informed decisions.

The 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.

Therefore, the answer is option (a) 6.15 and 6.85 hours.

A confidence interval is a statistical range of values within which we can be reasonably confident that the true value of a population parameter lies. It is commonly used in inferential statistics to estimate an unknown population parameter, such as a mean or a proportion, based on a sample from that population.

To calculate the 90% confidence interval for the average number of hours of sleep for working college students, we'll use the formula:

Confidence Interval = Sample Mean ± (Critical Value x Standard Error)

Where:

Sample Mean: 6.5 hours (the average number of hours of sleep)

Critical Value: t-value corresponding to a 90% confidence level with 100 degrees of freedom (101 students - 1)

Standard Error: Standard Deviation / Square Root of Sample Size

Let's plug in the values and calculate the confidence interval:

Standard Error = 2.14 / √101 ≈ 0.2139

Confidence Interval = 6.5 ± (1.660 x 0.2139)

Confidence Interval = 6.5 ± 0.3546

Lower Bound = 6.5 - 0.3546 ≈ 6.1454

Upper Bound = 6.5 + 0.3546 ≈ 6.8546

Rounding to the hundredths place, the 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.

Therefore, the answer is option (a) 6.15 and 6.85 hours.

Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

What is a linear equation?

A linear equation is an algebraic equation that represents a straight line on a graph. In general, a linear equation takes the form:

y = mx + b

A linear relationship between two variables, x and y, is one in which the change in y is directly proportional to the change in x. This means that for any change in x, there is a corresponding change in y that can be expressed as a constant multiple of x.

For example, if we have a linear relationship y = mx + b, where m is the slope of the line and b is the y-intercept, then if we increase x by 1 unit, y will increase by m units. This relationship holds true for all values of x and y along the line.

A proportional relationship, on the other hand, is a special case of a linear relationship in which the ratio of y to x is always the same constant. This means that if we increase x by 1 unit, y will increase by a constant multiple of x. In other words, the relationship between x and y is one of scaling, where the size of y is always a fixed multiple of the size of x.

Therefore, Table C represents a linear relationship that is also proportional. This is because the ratio of the output (y) to the input (x) is always constant, which is a characteristic of proportional relationships.

Answer:

C. (45+2+7)-(43+2+7) / 5+3

Step-by-step explanation:

To find the average rate of change of h(x) on the interval -3 ≤ x ≤ 5, we need to evaluate the following expression:

[h(5) - h(-3)] / (5 - (-3))

We have:

h(5) = 4(5) + 2 + 7 = 29

h(-3) = 4(-3) + 2 + 7 = -5

Substituting into the formula, we get:

[29 - (-5)] / (5 - (-3)) = 34 / 8 = 17 / 4

Therefore, the expression that gives the average rate of change of the function h(x) on the interval -3 ≤ x ≤ 5 is:

(a) Distance travelled in first 48 minutes = 40 km. (b)(i) Distance travelled in remaining journey = 30 km. (ii) Yes, Stanley arrived at Peter's house before 9:30 a.m. as he reached there at 9:28 a.m.

(a) To find the distance travelled for the first 48 minutes, we can use the formula:

distance = speed x time

The speed is 50 km/h and the time is 48/60 hours (since 48 minutes is 0.8 hours). So,

distance = 50 x 0.8

distance = 40 km

Therefore, Stanley travelled 40 km for the first 48 minutes of his trip.

(b) Let's use the formula for average speed:

average speed = total distance ÷ total time

We know that the total distance is the distance travelled in the first 48 minutes plus the distance travelled for the remaining journey. Let's call the distance for the remaining journey "d". We also know that the total time is 1 hour (60 minutes).

So,

70 = (40 + d) ÷ 1

40 + d = 70

d = 30

Therefore, the distance for the remaining journey is 30 km.

(i) To express the distance travelled for the remaining journey in terms of 1, we can use the formula we found in part (b):

d = 30 km

(ii) To find out if Stanley arrived at Peter's house before 9:30 a.m., we need to know the total time of his journey. We know that he left his home at 8:00 a.m. and his average speed was 70 km/h. So, the total distance he travelled is:

distance = speed x time

distance = 70 x time

We also know that the total distance is the distance for the first 48 minutes plus the distance for the remaining journey:

distance = 40 + 30

distance = 70 km

Therefore, the total time of his journey is:

time = distance ÷ speed

time = 70 ÷ 70

time = 1 hour

Since he arrived at Peter's house at 9:00 a.m. (1 hour after he left his home), we can conclude that he arrived before 9:30 a.m.

The matrix A does not eigenvector v corresponding to the given eigen value.

v is an eigenvector of A calculate corresponding eigenvalue,

A × v = λ × v

where A is the given matrix.

v is the given vector.

λ is the corresponding eigenvalue.

× denotes matrix multiplication.

Let's first calculate A × v we have,

A × v

= [-11 60] × [ 1 3λ]

= [-11-33λ    60+ 180λ]

Check A× v is equal to λ × v ,

λ × v =

λ × [ 1 3λ]

= [λ  3λ^2]

Set these two vectors equal to each other and get the following system of equations ,

-11-33λ = λ  __(1)

60+ 180λ = 3λ^2  ___(2)

From equation (1) we get,

⇒34λ = -11

⇒ λ = -11/34

Substituting this value of λ into the second equation, we have,

60+ 180λ = 3λ^2

⇒ 60 + 180(-11/34) = 3(-11/34)^2

⇒ (2040 -1980)/ 34 = 3(-11/34)^2

⇒ 60/34 = 3( 11/34)^2

⇒ 60 × 34 = 3 × 11 × 11

⇒20× 34 = 11 × 11

The exponential model for the population can be written as P = 20000 * 1.171^t, where P is the population after t years, 1.171 is the growth factor per year (100% + 17.1%), and 20000 is the initial population.

This equation assumes that the population grows continuously at a constant rate of 17.1% per year. It is an example of exponential growth, which means that the population increases at an increasingly faster rate over time.

Using this model, we can predict the population size at any point in the future. For example, after 5 years, the population would be P = 20000 * 1.171^5 = 41,992 organisms. It is important to note that this model is based on certain assumptions, such as unlimited resources and a constant growth rate, which may not always hold true in real-world scenarios.

et the initial value be represented by a and the rate of change by r.

The given information can be represented by the following equation:

a + 150r = 1,852

Since the flat-rate shipping cost is $25, the cost of the 150 shirts alone would be:

a + 150r - 25 = 1,827

The initial value, a, represents the cost of the shirts before any shirts were purchased. In this case, it would be the cost of the shirts if no shirts were purchased plus the flat-rate shipping cost of $25.

So, a = 1,827 + 25 = 1,852.

The rate of change, r, represents the increase in cost for each additional shirt purchased. In this case, it would be the cost of one shirt.

Over a year, the Blue Valley Glacier typically moves about the same distance as the Silver Lake Glacier, and Blue Valley has the same variability in its annual movement compared to Silver Lake.

The median annual movement of the Blue Valley Glacier is 300.2 feet, and the interquartile range is 14 feet.

The interquartile range indicates the spread of the data within the middle 50% of the data

So we know that the annual movement of the Blue Valley Glacier falls within a range of 300.2 ± 7 feet (i.e. 293.2 to 307.2 feet)

Similarly, the median annual movement of the Silver Lake Glacier is 300.4 feet, and the interquartile range is also 14 feet

So the annual movement of the Silver Lake Glacier also falls within a range of 300.4 ± 7 feet (i.e. 293.4 to 307.4 feet)

Since the ranges for both glaciers overlap and have the same size, we can conclude that they typically move about the same distance over a year, and that the variability in the annual movement of Blue Valley is comparable to that of Silver Lake.
