Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have
(2 + a)/2 = 4
(3 + b)/2 = 6
Solve for a and b :
(2 + a)/2 = 4
2 + a = 8
a = 6
(3 + b)/2 = 6
3 + b = 12
b = 9
So the coordinates of Q are (6, 9).
The height of a tree sapling was 3.15 inches last year. This year, the height is 5.38 inches. How much did the height of the tree sapling increase? Find the difference.
Answer:
2.23 inches
Step-by-step explanation:
Difference means subtraction and you subtract the smaller number from the bigger number. 5.38 - 3.15 = 2.23 in.
Answer:
2.23 inches
Step-by-step explanation:
We will subtract 3.15 from 5.38 because the problem is asking for the increase. We will take the new height and subtract the old height to see the difference.
5.38 - 3.15 = 2.23 inches

Thirty-three percent of all students at a high school like beef stew. Out of 300 students, 40 are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, what is the probability of a failure for this binomial experiment? 0. 33 0. 40 0. 57 0. 67.
Probabilities are used to determine the chances of an event.
The probability of a failure for the binomial experiment is (d) 0.67
The probability (p) that a student likes beef stew is given as:
[tex]\mathbf{p = 33\%}[/tex]
Using the complement rule, the probability (q) that a student does not like beef stew is calculated as:
[tex]\mathbf{q =1-p}[/tex]
Substitute 33% for p
[tex]\mathbf{q =1-33\%}[/tex]
Express 33% as decimal
[tex]\mathbf{q =1-0.33}[/tex]
Subtract 0.33 from 1
[tex]\mathbf{q =0.67}[/tex]
From the question, the probability (q) that a student does not like beef stew represents failure
Hence, the probability of a failure is (d) 0.67

Eunice, Helen and Essel shared $14,000 among themselves. Eunice had twice as much as Helen and Helin had twice as Essel. How much did Helen get?
Answer:
Helen amount = $2,000
Step-by-step explanation:
Helen amount = x
Eunice amount = 2 ( Helen amount) = 2x
Helin amount = 2 (Eunice amount) = 2(2x) = 4x
x + 2x + 4x = $14,000 Check Helen = x = $2,000
7x = $14,000 Eunice = 2x = $4,000
x = $14,000 ÷ 7 Helin = 4x = $8,000
x = $2,000

Tips ($) $92 $80 $76 $121 $109 $43 $87 $114 $99 $174 $88 $91

b) Find the equation of the trend line (line of best fit). Show your work. (2 points)
c) Predict the amount of tips that would be collected if 100 customers were served at the restaurant on a given day. Explain your reasoning. (2 points)
d) Explain how to use the regression calculator to make a reasonable prediction given a data table. (2 points)
Answer:
a) I am sorry, but I don't know this one.
b) y = mx + b
=> b = y-intercept = 0
=> m = slope = Rise/Run
=> Rise/Run = 120/65
=> Rise/Run = 24/13
=> Slope = 24/13
=> Our Equation: y = 24x/13
c) After drawing the trend line, we can conclude that if 100 costumers were served, the amount of tips would be about $185
d) To use a regression calculator, we must be given a table with x and y values. Then we insert the values in the calculator so that it can give us the whereabouts of a point and it can give us the trend line. After the trend line is given, we can make a prediction.

Solve for x. 9(-5 + x)= −108
pls help i don't have much time
Answer:
[tex]\huge\boxed{x = -7}[/tex]
Step-by-step explanation:
This problem utilizes the Distributive Property, which states that:
a(x + y) = ax + ay.
Thus, simply distribute to turn the equation into
9*(-5) + 9 * (x) = -108
-45 + 9x = -108
9x = -63
x = -7

the probability that a new microwave oven will stop working in less than 2 years is 0.05. the probability that a new microwave oven is damaged during delivery and stops working in less than 2 years is 0.04. the probability that a new microwave oven is damaged during delivery is 0.10. given that a new microwave oven is damaged during delivery, what is the probability that it stops working in less than 2 years?
Answer:
0.40
Step-by-step explanation:
0.04 divided by 0.10 = 0.4
Using conditional probability, it is found that there is a 0.4 = 40% probability that it stops working in less than 2 years.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Damaged during delivery.Event B: Stops working in less than 2 years.0.1 probability of being damaged during delivery, hence [tex]P(A) = 0.1[/tex].
0.04 probability of being damaged during delivery and stop working, hence [tex]P(A \cap B) = 0.04[/tex]
The conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.1} = 0.4[/tex]
0.4 = 40% probability that it stops working in less than 2 years.

y=x^2-5x+6
y=-4x+6
A (0,6) and (1,2)
B (-1,0) and (6,0)
C (-1,0) and (0,6)
D (0,-1) and (6,0)
Step-by-step explanation:
y = x² - 5x + 6
y = -4x + 6
x² - 5x + 6 = -4x + 6
x² - x = 0
x(x - 1) = 0
x = 0 and x = 1
y = -4x + 6 and y = -4x + 6
y = -4(0) + 6 and y = -4(1) + 6
y = 0 + 6 and y = -4 + 6
y = 6 and y = 2
Solution = (0,6) and (1,2)
