It is not reasonable to use a normal model for the sampling distribution of the sample because the data doesn't meet the success or failure consideration.

The sample has a size of 50 students. The probability that she guesses that about 10% of the class goes is 10%

This will be illustrated as:

1 - p = 1 - 10% = 1 - 0.10 = 0.90

np = 50 × 0.1 = 5. This implies the number of successes.

In this case, the number of successes is less than 10. This is because 5 is less than 10. Therefore, the data doesn't meet the condition.

Answer:

  10.97 seconds

Step-by-step explanation:

You want to know when a rocket will hit the ground if its height is given by y = -16x² +170x +61, where x is seconds after launch.

The formula for the solutions of a quadratic equation is ...

  \(\text{for }ax^2+bx+c=0\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

When we apply this to the equation y=0, we have ...

  \(x=\dfrac{-170\pm\sqrt{170^2-4(-16)(61)}}{2(-16)}=\dfrac{170\pm\sqrt{32804}}{32}\\\\x\approx 10.97\quad\text{seconds}\)

The rocket will hit the ground after about 10.97 seconds.

The equation of the line which is passing to a point and slope 2/3 will be y = 2/3x + 5.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the given information in the question,

The equation for the line in the slop form is,

y = mx + b

Slope, m = 2/3

y = 2/3x + b, it is representing a partial equation.

Substitute the given point (3, 7) in the above equation,

Answer:

Step-by-step explanation:

Number of bowls that Laura can make with 10lbs of clay is 16

To find out how many bowls Laura can make, we need to divide the amount of clay she has by the amount of clay needed to make one bowl.

Let's start by converting the fraction 3/5 into a decimal:

3/5 = 0.6

This means that Laura needs 0.6 lbs of clay to make one bowl.

Now we can divide the total amount of clay Laura has by the amount of clay needed for one bowl:

10 ÷ 0.6 = 16.67

Laura can make 16 complete bowls with 10 lbs of clay, and she will have some clay left over (0.07 lbs to be exact) that is not enough to make another full bowl.

According to the question the possible values for m are m = 0 and m = 1.

To find the value of m in the equation y ′′ + (y ′)² = 0, where y = mlnx is a nontrivial solution, we need to differentiate y with respect to x.

First, let's find the first derivative of y:

y' = d/dx (mlnx)

Using the chain rule, we get:

y' = m(1/x)

Now, let's find the second derivative of y:

y'' = d/dx (y')

= d/dx (m(1/x))

= -m/x²

Substituting y and its derivatives into the equation y'' + (y')² = 0, we have:

(-m/x²) + (m(1/x))² = 0

Simplifying this equation:

-m/x² + m²/x² = 0

Combining the terms with a common denominator:

(m² - m)/x² = 0

For this equation to hold true for all x ≠ 0, the numerator (m² - m) must be equal to 0:

m² - m = 0

Factoring out m:

m(m - 1) = 0

Setting each factor equal to zero:

m = 0 or m - 1 = 0

So, the possible values for m are m = 0 and m = 1.

Answer: 700

Step-by-step explanation:

The statement "the standard deviation of a single data set and the standard error of a sampling distribution is typically the same value" is FALSE.

The standard deviation (SD) is a statistical measurement that indicates how much data is dispersed. The SD calculation considers all data points, both above and below the mean, rather than simply the mean. SD can be calculated for a single data set, as well as the SD of the mean for a population, the SD of the mean for a sample, and the SD of the mean for a sampling distribution.

The standard error (SE) is a statistical measurement that shows how precise the mean of a population or sample is to the true value. The SE measures how the sample mean deviates from the true population mean. It's important to keep in mind that SE is the standard deviation of the mean for a population or sample, not the standard deviation of the raw data.The statement "the standard deviation of a single data set and the standard error of a sampling distribution is typically the same value" is false.

The reason being is that the standard deviation of a single data set and the standard error of a sampling distribution are not the same value. The standard deviation of a single data set measures the variability of the data set, while the standard error of a sampling distribution measures the precision of the sample mean as an estimator of the population mean.

Answer:

The expression (8-i)/(2+i) in standard form is, 3 - 2i

Step-by-step explanation:

The expression is,

(8-i)/(2+i)

writing in standard form,

\((8-i)/(2+i)\\\)

Multiplying and dividing by 2+i,

\(((8-i)/(2+i))(2-i)/(2-i)\\(8-i)(2-i)/((2+i)(2-i))\\(16-8i-2i-1)/(4-2i+2i+1)\\(15-10i)/5\\5(3-2i)/5\\=3-2i\)

Hence we get, in standard form, 3 - 2i

The expression (8-i)/(2+i) in standard form a+bi is (15 - 10i) / (3 + 4i).

To write the expression (8-i)/(2+i) in standard form a+bi, we need to eliminate the imaginary denominator. We can do this by multiplying the numerator and denominator by the conjugate of the denominator.

The conjugate of 2+i is 2-i. So, we multiply the numerator and denominator by 2-i:

(8-i)/(2+i) * (2-i)/(2-i)

Using the distributive property, we can expand the numerator and denominator:

(8(2) + 8(-i) - i(2) - i(-i)) / (2(2) + 2(i) + i(2) + i(i))

Simplifying further:

(16 - 8i - 2i + i^2) / (4 + 2i + 2i + i^2)

Since i^2 is equal to -1, we can substitute -1 for i^2:

(16 - 8i - 2i + (-1)) / (4 + 2i + 2i + (-1))

Combining like terms:

(15 - 10i) / (3 + 4i)

Therefore, the expression (8-i)/(2+i) in standard form a+bi is (15 - 10i) / (3 + 4i).

The probability that a randomly selected box of cold medicine will cost more than $15 is approximately 0.8413.

To find the probability, we need to calculate the area under the normal distribution curve to the right of $15. We can use the z-score formula to standardize the value of $15 and then look up the corresponding area in the standard normal distribution table or use statistical software.

First, we calculate the z-score:

z = (x - μ) / σ

where x is the value ($15), μ is the mean ($17), and σ is the standard deviation ($4.5).

z = (15 - 17) / 4.5 = -0.4444

Using the standard normal distribution table or a calculator, we find that the area to the left of z = -0.4444 is approximately 0.3581. Since we want the area to the right of $15, we subtract this value from 1 to get the probability of the box costing more than $15:

P(X > $15) = 1 - 0.3581 = 0.6419

Therefore, the probability that a randomly selected box of cold medicine will cost more than $15 is approximately 0.6419 or 64.19%.

This gives us a dendrogram with three levels, where the first level has two clusters {{7,10},{20,28}} and {35}, the second level has two clusters {{7,10,20,28},35}, and the third level has only one cluster {{7,10,20,28,35}}.

What is a sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

To perform hierarchical clustering using single linkage, we start by treating each point as its own cluster, and then iteratively merge the two closest clusters until only one cluster remains. We use the single linkage method, which defines the distance between two clusters as the minimum distance between any two points in the clusters.

First, we calculate the pairwise distances between each point:

  7    10   20   28   35

7   -    3    13   21   28

10  3    -    10   18   25

20  13   10   -    8    15

28  21   18   8    -    7

35  28   25   15   7    -

Next, we find the two closest points/clusters and merge them:

  7,10  20   28   35

7,10  -    10   18   25

20    10   -    8    15

28    18   8    -    7

35    25   15   7    -

The closest points/clusters are 7 and 10, so we merge them to form a new cluster {7,10}.

  7,10  20,28  35

7,10  -    18     25

20,28 18   -      7

35    25   7      -

The closest points/clusters are now {20,28} and 35, so we merge them to form a new cluster {{20,28},35}.

 7,10  {20,28,35}

7,10  -    7

{20,28,35} 7    -

The closest points/clusters are now {7,10} and {{20,28},35}, so we merge them to form a new cluster {{{7,10},{20,28}},35}.

Hence, This gives us a dendrogram with three levels, where the first level has two clusters {{7,10},{20,28}} and {35}, the second level has two clusters {{7,10,20,28},35}, and the third level has only one cluster {{7,10,20,28,35}}.
