intersects the segment at point P. Which
statement is true?
(A)
© AP = 2 AB
PA & BP
(В)
AB = AP
BP = 2 AB
Answer:
a)
Step-by-step explanation:
PA ≅ BP
Perpendicular bisector means it divides the line into two equal part at 90°
Rearrange x = 3g + 2 to make g the subject g=?
Step-by-step explanation:
x=3g+2
you need to move the equation to the other side, first you'd start with the one furtherest from g, which is is 2.
x = 3g
-2. - 2
and minus it from both sides
x-2=3g
3g is like 3x, which is 3 times x and you need to use the opposite operators so times would become divide.
so now it becomes x-2 over 3=g

Answer:
[tex]\dfrac{6x+2}5}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{3x}{5}+\dfrac{2}{5}+\dfrac{3x}{5}[/tex]
We need to write the equivalent expression for the above expression.
Taking like terms together,
[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]
So, the equivalent expression is [tex]\dfrac{6x+2}5}[/tex].

What is the value of the missing angle?
Answer:
105
Step-by-step explanation:
all angles inside a triangle add up to equal 180, the inside angle at R is 75 degrees, the TP line is obviously a 180 degree angle, because it's just a straight line, so you subtract 75 from 180 to get 105

Find the slope of the line that passes through (10, 92) and (97, -3).
Answer:
-95/87
Step-by-step explanation:
Formula to find slope: (y2-y1) / (x2-x1)
In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.
We substitute these numbers into the equation.
(-3-92) / (97-10)
Then we simplify this by subtracting.
-95/87 is our final answer.

A standard die is rolled twice find each probability.
Answer:
I see you are rolling a standard fair six-sided die twice. There are 6 equally likely outcomes on each roll of the die. Die Roll #1: P(Perfect square) =1/3 The winning outcomes are 1 and 4, this makes the fraction 2/6, which reduces to 1/3.

The probabilities for the following statements are:
a) 1/4
b) 1/18
c) 1/3
d) 1/12
e) 1/6
f) 1/36
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The sample space for rolling a die twice.
= {1, 2, 3, 4, 5, 6 } x {1, 2, 3, 4, 5, 6}
= {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6) }
The number of possible outcomes.
= 36.
Now,
The number of outcomes where both are odd.
= { (1, 1), (1, 3), (1, 5), (3, 1), (3, 3), (3, 5), (5, 1), (5, 3), (5, 5) }
The probability that both are odd.
= 9/36
= 1/4
The number of outcomes where both are a perfect square.
= {1, 1), (4, 4) }
The probability that both are perfect squares.
= 2/36
= 1/18
The number of outcomes where the first is even and the second is less than 5.
= { (2, 1), (2, 2), (2, 3), (2, 4), (4, 1), (4, 2), (4, 3), (4, 4), (6, 1), (6, 2), (6, 3), (6, 4) }
The probability that where first is even and second, is less than 5.
= 12/36
= 1/3
The number of outcomes where the first is prime and the second is 6.
= { (2, 6), (3, 6), (5, 6) }
The probability where the first is prime and the second is 6.
= 3/36
= 1/12
The number of outcomes where both are the same.
= { (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6) }
The probability that both are the same.
= 6/36
= 1/6
The number of outcomes of at least 4 both times.
= {(4, 4)}
The probability that at least 4 both times.
= 1/36
Thus,
The probabilities for each statement are given above.

Solve the formula a(m - r) + t = s for a
Answer:
[tex]\huge\boxed{a =\frac{s-t}{m-r}}[/tex]
Step-by-step explanation:
In order to convert an equation to solve for another variable, we need to algebraically manipulate the problem until we're left with a isolated on one side.
Step 1: Subtract [tex]t[/tex] from both sides
[tex]a(m-r) + t - t = s - t[/tex] [tex]a(m-r) = s-t[/tex]Step 2: Divide both sides by [tex]m- r[/tex]

Henry rolls a fair dice 42 times. How many times would Henry expect to roll a number greater than 5?
Answer:
7 times
Step-by-step explanation:
There is one number greater than 5 on a dice - that is the number 6.
So probability of throwing a six = 1/6.
So it is 42 * 1/6.
