The test statistic-z or z-score will be 1.635.

What is test statistic-z?

A z-score, also known as a z-statistic, is a number that represents how many standard deviations above or below the mean population a z-test score is. It is essentially a numerical measurement that describes the relationship of a value to the mean of a collection of values. A z-score of 0 implies that the data point's score is the same as the mean score. A z-score of 1.0 indicates that the result is one standard deviation from the mean. Z-scores can be positive or negative, with a positive number indicating that the score is higher than the mean and a negative value indicating that it is lower than the mean.

Let p indicate the proportion of customers who are satisfied.

P=0.64

n=number of customers surveyed =125

x=number of satisfied consumers in the survey=89

p=89/125=0.71

The test statistic-z is calculated using the following formula,

z=(p-P)/√(P(1-P)/n)

=(0.71-0.64)/√0.64(1-0.64)/125

=0.07/√0.00184

=0.07/0.0428

=1.635

The test statistic-z is 1.635

Triangles E and F are not to be congruent to any other triangles.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We have to check triangles which appears not to be congruent to any others.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The triangles A and B are congruent as they have same shape and same angles.

The triangles C and D have same shape and same angles so they are congruent.

The triangles E and F are not congruent to any of the other triangles because they have unique shape and angles.

Hence, Triangles E and F are not to be congruent to any other triangles.

Step-by-step explanation:

Answer:

a. $76.00

b. y = 23x - 76

Step-by-step explanation:

a. If Anton earned $23 every week for twelve weeks, his total revenue would be 23 (12) = 276 dollars. He only had $200 after paying his parents back, though, so that means if you take away the $200 leftover money he got (after paying his parents back) from the $276 he earned over the 12 weeks, you'll get 276 - 200 = he borrowed $76.00 from his parents.

b. Anton is earning $23 every week, so the money, y, that he'll have after x weeks is y = 23x. But since he borrowed $76 from his parents, that much money should be subtracted from his money-making equation, leaving us with y = 23x - 76. Hope this was helpful!

Assume the random variable X is normally distributed with mean μ = 50 and standard deviation σ = 7, has the 87.29%. probability of P (X > 42)

The random variable X is normally distributed with mean μ = 50 and standard deviation σ = 7.

To find the probability P(X > 42), we need to find the z-score first using the formula:

z = (X - μ) / σ

z = (42 - 50) / 7

z = -1.14

Now, we can find the probability P(X > 42) using the standard normal distribution table or calculator as follows:P(X > 42) = P(Z > -1.14)

From the standard normal distribution table, we can find the area to the left of z = -1.14, which is 0.1271.

Therefore, the area to the right of z = -1.14 (i.e., P(Z > -1.14)) is:

P(Z > -1.14) = 1 - P(Z < -1.14) = 1 - 0.1271 = 0.8729

Therefore, the probability that X is greater than 42 is 0.8729 or approximately 87.29%.

There are 192 buffalo in the park at the end of year 3.

Now, At the beginning of year 1, there were 81 buffalo in the park.

And, At the end of year 1, the number of buffalo in the park would be 4/3 times the number at the beginning of the year:

= 81 x 4/3

= 108

So there are 108 buffalo in the park at the end of year 1.

And, At the end of year 2, we'll apply the same formula:

= 108 x 4/3

= 144

So there are 144 buffalo in the park at the end of year 2.

Finally, at the end of year 3:

144 x 4/3 = 192

Therefore, there are 192 buffalo in the park at the end of year 3.

The value of the triple integral is -16.

Triple integral is a mathematical concept used in calculus to calculate the volume of three-dimensional objects. It extends the concept of a single integral to functions of three variables and integrates over a region in three-dimensional space.

The triple integral of a function f(x, y, z) over a region E in three-dimensional space is denoted by:

∭E f(x, y, z) dV

We can set up the triple integral as follows:

∫∫∫ 16y dV

Where the limits of integration are:

0 ≤ x ≤ 2

0 ≤ y ≤ (2- \(x^2\)z)/(2y)

0 ≤ z ≤ 2/\(x^{2y\)

Note that the upper bound of integration for y is not a constant, but depends on both x and z.

Integrating with respect to y first, we get:

∫∫∫ 16y dV = ∫0^2 ∫\(0^(2-x^2z)/(2x)\)∫\(0^(2/x^2y) 16y dz dy dx\)

= ∫\(0^2\) ∫\(0^(2-x^2z)/(2x) 32/x dx dz\)

= ∫\(0^2\) [16(\(2-x^2z)/x^2\)] dz

= ∫\(0^2 (32/x^2 - 16z)\) dz

= 32∫\(0^2 x^-2 dx - 16\)∫\(0^2\)z dz

= 16 - 16(2)

= -16

Therefore, the value of the triple integral is -16.

Answer:

Your full equation is then y = -3*x + 80.

Step-by-step explanation:

This sounds like a linear equation that can be put in "y = m*x + b" form because there is a constant Y-intercept value ("b," the starting point) and a constant slope ("m," the rate of change).

The trick here is to pick out these values from the word problem. The first thing to look for are key words like "starting at,"  "at time 0," or "when x = 0." These describe when the line crosses the Y axis (which is where x = 0). This number is also the "b" from the equation for a line: y = m*x + b. Your problem contains the phrase "starting at 80 degrees Fahrenheit," so our Y-intercept is b = 80 degrees Fahrenheit.

The next thing to look for is the slope, m. The slope of the line explains how fast it changes. A very big (or very negative) value of m means a steeper line; a value of m closer to zero means a line that looks more horizontal (i.e. it doesn't change very fast). In your problem, the temperature "dropped 3 degrees per minute." Because the temperature is getting lower as time passes, the slope of the line will be negative. So, m = -3 degrees Fahrenheit per minute.

Step-by-step explanation:

The surface area of a square pyramid = 1/2 * slant height * base perimeter + area of base

 The slant height is 5 cm

The base perimeter is 4 * 5 cm = 20 cm

The area of the base is 5 cm * 5 cm = 25 cm**2

Plugging into the formula the area =

1/2 * 5 cm * 20 cm + 25 cm**2 =

5 cm * 10 cm + 25 cm**2 =

50 cm**2 + 25 cm**2 = 75 cm**2

The probability that an employee selected at random earns more than $50,000 per year, given that they are a college graduate, is 66.7%.

The probability of an employee being a college graduate is 20%, and the probability of an employee earning more than $50,000 per year is 25%. The probability of an employee being a college graduate and earning more than $50,000 per year is 15%.

The probability that an employee selected at random earns more than $50,000 per year, given that they are a college graduate, can be calculated using Bayes' theorem. Bayes' theorem states that the probability of an event A given an event B is equal to the probability of event A and event B happening divided by the probability of event B happening.

In this case, event A is an employee earning more than $50,000 per year, and event B is an employee being a college graduate. The probability of event A and event B happening is 15%. The probability of event B happening is 20%.

Therefore, the probability of event A given event B is 15% / 20% = 0.75 = 66.7%.
