When the distributive property is in play, you multiply all the numbers in the parenthesis by the number that's right next to it. In this case, you're multiplying 6 to all of the numbers in the paranthesis (5x - 3y +4).

-Bayes' theorem is used to revise probabilities when one has new information.

-Bayes' theorem is used to revise probabilities when one has new information. It relates the conditional probabilities of two events, A and B, as follows:

\(P(\frac{A}{B})= P(\frac{B}{A}) \frac{P(A)}{P(B)}\)

-where P(A|B) is the conditional probability of A given that B has occurred, \(P(\frac{B}{A})\) is the conditional probability of B given that A has occurred, P(A) is the prior probability of A, and P(B) is the prior probability of B.

-Bayes' theorem allows us to update our knowledge about the probability of A after we have observed B. It is widely used in fields such as statistics, machine learning, and artificial intelligence.

Answer:

D

Step-by-step explanation:

According to the Factor Theorem:

In order for a factor in the form of \((x-a)\) to be a root for a function \(f(x)\), \(f(a)\) must be 0.

Our factor is \((x-1)\).

Therefore, \(a=1\).

So, we will evaluate \(f(1)\) for all the choices.

Doing so, we can see that, starting from the top, we have:

\(\begin{aligned}f_1(1)&=-12\\ f_2(1) &=8 \\ f_3(1)&=24 \\ f_4(1)&=0 \end{aligned}\)

The choice that yields 0 as an answer is D.

So, the function for which \((x-1)\) is a real root is choice D.

okay don't feel bad, you actually got it right, let me help you with some holes!

You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1

the vertical change is -1 horizontal change is 3 so by rise/run=-1/3

-1/3 is the slope

for the second problem this is confusing but just read and try to analyze

vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)

The y intercept is the point where the line hits the y axis, so at point (0, 5)

The function is y=mx+b

m is the slope

b is the y intercept

The minimum and maximum allowed baseball masses are 143 grams and 147 grams

The given parameters are

Mass = 145 grams

Vary = 2 grams

This means that the allowed baseball masses are

Allowed baseball masses = Mass  ± Vary

This gives

Allowed baseball masses = (145 - 2, 145 + 2) grams

Evaluate

Allowed baseball masses = 143 grams, 147 grams

The lake activity with a central angle of  \(39.6^\circ\) is Wakeboarding.

11. the number of tortilla sandwich wraps falling into each interval can be represented by the height or area of the bars. This allows for an easy visualization of the distribution of the data.

12. To determine which bus typically has the faster travel time, we need to compare the measures of center for each data set. Since there are outliers in both data sets, the median would be a more appropriate measure of center than the mean.

For Bus 14, the median is (10 + 12)/2 = 11.

For Bus 18, the median is (10 + 14)/2 = 12.

Therefore, Bus 18 typically has the faster travel time, with a median of 12 minutes.

13. The IQR (interquartile range) is the best measure of variability for the data because it is less sensitive to outliers than the range, and it gives us an idea of how spread out the middle 50% of the data is.

To find Q1, we need to find the median of the lower half of the data: (1+2)/2 = 1.5.

To find Q3, we need to find the median of the upper half of the data: (8+8+8)/3 = 8.

Therefore, the IQR = Q3 - Q1 = 8 - 1.5 = 6.5.

14. To determine the central angle of each lake activity, we need to calculate the percentage of campers who chose each activity and then multiply that percentage by 360 (the total degrees in a circle).

The percentage of campers who chose Kayaking is 15%, so the central angle would be 0.15 x 360 = 54°.

The percentage of campers who chose Wakeboarding is 11%, so the central angle would be 0.11 x 360 = 39.6°.

The percentage of campers who chose Windsurfing is 7%, so the central angle would be 0.07 x 360 = 25.2°.

The percentage of campers who chose Waterskiing is 13%, so the central angle would be 0.13 x 360 = 46.8°.

The percentage of campers who chose Paddleboarding is 54%, so the central angle would be \(0.54 x 360 = 194.4^\circ.\)

I cannot draw here, but I can show and tell you how to find 2 points of the individual lines that you can then mark on the chart and draw the line through them.

1)

y = 7/2 x - 2

so, the first and easiest point is the y-intercept (where x = 0).

x = 0, therefore, y = -2

so, the first point is (0, -2)

for the second point : what value of x would eliminate the fraction and make this whole integer number calculations ?

well, x = 2 !

so,

y = 7/2 × 2 - 2 = 7 - 2 = 5

and our second point is (2, 5)

2)

y = -6x + 3

the same principles. first x = 0, therefore y = 3

the first point is (0, 3)

for the second point we can choose any integer x, as all the other terms are integer too.

let's pick x = 1

y = -6×1 + 3 = -6 + 3 = -3

so, the second point is (1, -3)

3)

y = -5

this just means that for every possible value of x the resulting y value is -5.

that means it is a horizontal line through y = -5 or (0, -5)

4)

y = 6/5 x + 1

the same principles. x = 0, therefore y = 1

the first point is (0, 1)

for the second point, again, what x eliminates the fraction and makes all an integer operation ?

well, x = 5.

y = 6/5 × 5 + 1 = 6 + 1 = 7

ok, 7 is off the chart, so let's use x = -5 instead.

y = 6/5 × -5 + 1 = -6 + 1 = -5

so, the second point on the chart is (-5, -5)

The disjunction of -p or -q can be written as (-p) v (-q). So, we have to find the truth value of (-p) v (-q). So, the compound statement for the disjunction of -p or -q is (-p) v (-q), and its truth value is true.

using the following statements: p: There are 14 inches in 1 foot.

q: There are 3 feet in 1 yard.

Solution: We know that 1 foot = 12 inches, which means that there are 14 inches in 1 foot can be written as 14 < 12. But this statement is false because 14 is not less than 12. Therefore, the negation of this statement is true, which gives us (-p) as true.

Now, we know that 1 yard = 3 feet, which means that there are 3 feet in 1 yard can be written as 3 > 1. This statement is true because 3 is greater than 1. Therefore, the negation of this statement is false, which gives us (-q) as false.

Now, we can use the values of (-p) and (-q) to find the truth value of (-p) v (-q) using the disjunction rule. The truth value of (-p) v (-q) is true if either (-p) or (-q) is true or both (-p) and (-q) are true. Since (-p) is true and (-q) is false, the disjunction of (-p) v (-q) is true. Hence, the compound statement for the disjunction of -p or -q is (-p) v (-q), and its truth value is true.
