Recent test scores on the Law School Admission Test (LSAT) are normally distributed with a mean of 162.4 and a standard deviation of 15.9. What is the probability that the mean of 8 randomly selected scores is less than 161?
Answer:
0.40166
Step-by-step explanation:
When given random number of samples, we solve using the z score formula:
z = (x-μ)/σ/√n where
x is the raw score= 161
μ is the population mean = 162.4
σ is the population standard deviation = 15.9
n is random number of samples = 8
Hence,
z = 161 - 162.4/15.9/√8
z = -0.24904
Probability value from Z-Table:
P(x<161) = 0.40166
The probability that the mean of 8 randomly selected scores is less than 161 is 0.40166

Answer:
y-intercept: -5
Slope: 4
Equation: y = 4x - 5
Step-by-step explanation:
✔️The y-intercept is the value of y when x = 0. From the table of values, it shows that when x = 0, y = -5. Therefore:
y-intercept (b) = -5
✔️using two pairs from the table, (1, -1) and (2, 3):
[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 -(-1)}{2 - 1} = \frac{4}{1} = 4 [/tex]
Slope = 4
✔️To write an equation for the function, substitute m = 4, and b = -5 into y = mx + b.
Thus:
y = 4x +(-5)
y = 4x - 5

Ava is making Vampire punch for the Halloween party. The recipe makes 12 servings and calls for 3/5 cups of cranberry juice. how much cranberry juice will she need for 15 servings
Answer:
15/20 cups of cranberry juice
Step-by-step explanation:
3/5 cranberry juice makes 12
12/2=6
3/5= 0.3
6/2=3
0.3/2= 0.15
0.15 = 3/20
3/20 cranberry juice makes 3 servings.
add 3 and 12 to make 15 servings, add 3/5 and 3/20.
3/5= 12/20
12/20 + 3/20 = 15/20 cups of cranberry juice

A survey of 800 students yielded the following information: 519 were seniors, 430 were commuters, and 300 of the seniors were commuters. How many of the 800 surveyed students were seniors or were commuters?
Answer:
The number is [tex](S \ u \ C ) = 649[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 800
The number of seniors is S = 519
The number of commuters is C = 430
The number of of seniors that are commuters is [tex](S\ n \ C )= 300[/tex]
Generally the number of 800 surveyed students who were seniors or were commuters is mathematically evaluated as
[tex](S \ u \ C ) = S + C - ( S \ n \ C )[/tex]
=> [tex](S \ u \ C ) = 519 + 430 - 300[/tex]
=> [tex](S \ u \ C ) = 649[/tex]

If we find that the null hypothesis, Upper H Subscript 0 Baseline colon beta Subscript j Baseline equals 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should:___________
Answer:
Remove the variable from the Model
Step-by-step explanation:
Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.
Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.
So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

Solution:The y-intercept, b, is the point where the graph intersects the y-axis.It's usually written as:(0, b).We already know what b stands for. It stands for the y-intercept.Since the graph intersects the y-axis at (0, 1) the y-intercept is (0, 1) or 1.Hope it helps.

I don't get this find all missing angles what does it mean how do I do it
First, you can find angle 1 by using the triangle angle formula, stating that all angles add up to 180 deg. Thus, angle 1 is equal to 180-72-57= 51 deg.
Next, you can find angle 2 by using the right angle shown. This means that angle 2 plus 72 deg = 90 deg. Thus, angle 2 is equal to 90-72= 18 deg.
For angle 3, notice that it is bordering the other angle on a straight line. A straight line is equal to 180 deg. This means that angle 3 + 57 deg = 180 deg. Thus, angle 3 is equal to 180-57= 123 deg.
Angle 4 can be found by using the triangle angle formula used for angle 1. In this case, angle 2+3+4 will equal 180 deg. Thus, angle 4 is equal to 180-18-123= 29 deg.
Answer:
1= 51
2= 18
3= 123
4= 39
Step-by-step explanation:
First you must know that all triangles equal 180. From there you can add and subtract the known numbers to get your answers. For example with angle 1, because you are give 72 and 57 you must add them together to get 129 then subtract that from 180 to get 51. You can do similar steps for all the angles to receive the answers.

Jalen had read 14 chapters out of the book .. if this is 56% of the chapters, how many chapters are in the book?
Answer:
25 Chapters
Step-by-step explanation:
We are given:
Number of Chapters read = 14
Percentage of Book finished = 56%
Number of Chapters in the Book:
Since 56% of 'x' chapters is 14:
[tex]x*\frac{56}{100}[/tex] = 14
[tex]x = \frac{14 * 100}{56}[/tex] [multiplying both sides by 100/56]
[tex]x = \frac{100}{4}[/tex] [since 14*4 = 56]
x = 25
Therefore, the book has 25 chapters
Answer:
The book has a total of 25 chapters.
Step-by-step explanation:
We are given that Jalen has read 14 chapters of his book. We are also given that 14 chapters is 56% of the entire book. We need to find how many chapters are in the book.If 14 is 56% of the book, we can set up a proportion that can find the total number of chapters in the book.
A proportion looks like:
[tex]\displaystyle \frac{a}{b} = \frac{c}{d}[/tex]Our first fraction will be the two values we are given: 14 chapters and 56% of the book.
[tex]\displaystyle \frac{14}{56}[/tex]Then, our second fraction will contain an unknown variable. We would need to complete this many chapters to complete the book, so 100% of the book would be read once a certain number of chapters are reached. Therefore, we don't know how many chapters are needed to complete the book, so this is our unknown variable. We can define this as x.
Therefore, our second fraction is:
[tex]\displaystyle \frac{x}{100}[/tex]Now, we can set these fractions equal to each other.
[tex]\displaystyle \frac{14}{56} = \frac{x}{100}[/tex]Then, we can cross multiply our fractions to create an equation. Following our sample proportion, we would get:
[tex]{ac = bd}[/tex]So, we can follow the same policy with our proportion.
[tex]\displaystyle (14)(100) = (56)(x)\\\\1400 = 56x\\\\56x = 1400\\\\\frac{56x}{56} = \frac{1400}{56}\\\\x = 25[/tex]
Therefore, 56% of the book is 14 chapters. With this information, we have determined that 100% of the book is 25 chapters.
