Pick the best estimate for the correlation coefficient.
The best estimate for the correlation coefficient based on the given scatter plot is: A. 0.85.
What is Correlation Coefficient?Correlation coefficient can be defined as a measure of the strength of the linear relationship that exist between two variables. The correlation coefficient between two variables can range from -1 to 1.
A value that is closer to 0 shows a strong correlation coefficient between the two given variables and it shows that the data points on a scatter plot are not far apart from each other along the line of best fit.
On the other hand, values that are farther from 0 shows a weak correlation between the two variables, which also means that the data points on a scatter plot would be farther apart from each other.
In the scatter plot given, the data points slopes upwards and are not far apart from each other. This definitely shows a positive correlation coefficient that is close to 1.
The best estimate is therefore A. 0.85.

The most appropriate choice for equation of line in slope intercept form will be given by-
y = 4x + 17 is the required equation of line
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Here,
Slope = 4
The line passes through (-3,5)
Equation of line = y - 5 = 4[x - (-3)]
y - 5 = 4x + 12
y = 4x+ 12 + 5
y = 4x + 17

Define normal distribution.The theoretical curve that shows the probability that an experiment will produce a particular result in statistics. The symmetrical and bell-shaped curve shows that whereas trials frequently provide results that are near to the average, they can also vary significantly from it on occasion.
The standard normal distribution is a type of normal distribution that has a mean of 0 and a standard deviation of 1. The standard deviation shows how far a given measurement deviates from the mean, and the standard normal distribution is centered at zero. Sixty-eight percent of the observations for the normal distribution are within one standard deviation of the mean, ninety-five percent are within two standard deviations of the mean, and 99 percent of the data are three standard deviations or less from the mean.

In the following diagram, Figure D'C'B'A is obtained by a dilation of Figure DCBA about the point A
The area of the figure formed by the dilation is 36 square units.
Area is particularly essential in modern mathematics. In addition to its importance in geometry and calculus, area is linked to the determination of determinants in linear algebra and is an essential feature of surfaces in differential geometry.
A dilation occurs when an figure is reduced to a smaller size using a fixed center.
From the given diagram we can find the sides of the square that is the transformed image as 9 - 3 = 6 units
Area of the A'B'C'D' square = 36 square units.
Side of the original square = 18 units.
Area of the ABCD square = 18² = 324 square units
Scale factor of dilation = 324/36 = 9 times.
Hence from the figure we can calculate the area of the transformed figure to be 36 square units which is dilated by a factor of 9 times.

[tex]\textsf{b.} \quad h=\dfrac{120}{17}-\dfrac{23}{17}b[/tex]
Step-by-step explanation:
Given equation:
[tex]5.75b + 4.25h = 30[/tex]
Part aTo solve the equation for b, subtract 4.25h from both sides:
[tex]\implies 5.75b + 4.25h -4.25h= 30-4.25h[/tex]
[tex]\implies 5.75b = 30-4.25h[/tex]
Divide both sides by 5.75:
[tex]\implies \dfrac{5.75b}{5.75} = \dfrac{30-4.25h}{5.75}[/tex]
[tex]\implies b= \dfrac{30-4.25h}{5.75}[/tex]
[tex]\implies b= \dfrac{30}{5.75}-\dfrac{4.25h}{5.75}[/tex]
[tex]\implies b=\dfrac{120}{23}-\dfrac{17}{23}h[/tex]
Part bTo solve the equation for h, subtract 5.75b from both sides:
[tex]\implies 5.75b + 4.25h -5.75b= 30-5.75b[/tex]
[tex]\implies 4.25h = 30-5.75b[/tex]
Divide both sides by 4.25:
[tex]\implies \dfrac{4.25h}{4.25} = \dfrac{30-5.75b}{4.25}[/tex]
[tex]\implies h= \dfrac{30-5.75b}{4.25}[/tex]
[tex]\implies h= \dfrac{30}{4.25}-\dfrac{5.75b}{4.25}[/tex]
[tex]\implies h=\dfrac{120}{17}-\dfrac{23}{17}b[/tex]

To solve -3 = -19 + d/5, what steps would you use?
The value of d is 4 by law of exponents.
What are exponents?
The mathematical procedure known as exponentiation uses the base b and the exponent, or power, n. Its translation is "b to the n" and its symbol is Bn. The how many times a number has been amplified by itself is known as an exponent. When written as 23, the phrase "2 to the third" actually means "2 x 2 x 2 = 8," not 23, and "2 x 3 = 6," respectively.
Keep in mind that a number multiplied by one equals the original number.
Exponents are a way to express very big numbers as powers of smaller numbers. The exponent, so to speak, is the amount of times an integer has been multiplied by itself.

Step-by-step explanation:
A Hexagon has 720 degrees in total
Subtract all the known angles
720 - 90 - 90 - 146 - 130 - 135 = m
m = 129 degrees
Answer:
m = 129°
Step-by-step explanation:
Finding the unknown angle in the polygon:Find the sum of angles of the polygon using the formula,
Sum of angles of polygon = (n - 2)*180
n is the number of sides. n = 6
= ( 6- 2) *180

Using the uniform distribution, it is found that:
1. The area under the curve is of 1.
2. The mean is of 15 minutes.
3. The standard deviation is of 8.7 minutes.
4. The probability that a student will wait more than 25 mins for a bus is of 1/6.
What is the uniform probability distribution?The uniform distribution has two bounds, given by a and b, in which each possible outcome is equally as likely.
The area under the curve gives the sum of the probabilities of all outcomes, hence it is of 1, as the sum of the probabilities is of 1 = 100%.
The time that a student waits is uniformly distributed from 0-30 mins, hence the bounds of the interval are given by:
a = 0, b = 30.
The mean is given by:
M = (a + b)/2 = 30/2 = 15 minutes.
The standard deviation is given by:
[tex]S = \sqrt{\frac{(b - a)^2}{12}} = \sqrt{\frac{900}{12}} = 8.7[/tex]
The probability of finding a value higher than a measure x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Considering the bounds in this problem, the probability that a student will wait more than 25 mins for a bus is:
P(X > 25) = (30 - 25)/(30 - 0) = 5/30 = 1/6.
