Answer:
B. 7/20
Step-by-step explanation:
P(A | B) = P(A∩B) / P(B) is the formula for conditional probability
= (7/40) / (1/2)
Copy dot flip
= 7/40 * 2/1
=7/20

Find the 35th term in the arithmetic sequence 3, 9, 15, 21, …
Answer:
208
Step-by-step explanation:
First term = a = 4
Common difference = d = a2 - a1 = 9 - 3 = 6
35th term = a + (35 - 1)d
4 + (35 - 1)6
4 + (34)6
4 + 204
208
Answer:
207
Step-by-step explanation:
An=A1+(n-1)×R
A35=3+(35-1)×(9-3)
A35=3+34×6
A35=3+204
A35=207

Answer:
A = -8
B = 27
X = 6
y = 3
z = 9
Step-by-step explanation:
hope that helps
Answer:
Below in bold.
Step-by-step explanation:
A = (-2)^3 = -8.
B = (3)^3 = 27.
j^(3*3) = j^9 and j^(1*3) = j^3
j^9 / j^3 = j^6
So x = 6.
y = 3.
m^(3 * 3) = m^9.
z = 3*3 = 9.
If DE = X+1, EF = x-2, DF =15, and E is

Find the slope of the line whose equation is 8 y = 4 − 3 x .
Answer:
-3/8
Step-by-step explanation:
8y = 4 - 3x
~Divide 8 to everything
y = 1/2 - 3/8x
~Reorder
y = -3/8x + 1/2
In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.
Best of Luck!

R 3. The mean of 4 numbers is 8. Three of the numbers add up to 22. What is the last number?
let the last number be x
we know,
[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]
So,

How many Christmas trees were sold on sat and sunday?
Hello :D
Let's form an equation:
x/5 = 27
Let's form another equation:
(x+y)/7 = 34
Rearrange equation one so it is x = 27 x 5 = 135
Now we can substitute this value into equation 2:
(135 + y)/7 = 34
135 + y = 238
y = 238 - 135
y = 103
Answer is 103
Answer:
103 christmas trees.
Step-by-step explanation:
total trees sold in the first five days:
[tex]27 \times 5 = 135[/tex]
total trees sold in this week:
[tex]34 \times 7 = 238[/tex]
The answer is:
[tex]238 - 135 = 103[/tex]
Find an equation for the perpendicular bisector of the line segment whose endpoints are (-1,-7)(−1,−7) and (9,1)(9,1).
Answer:
y = -5/4 - 31/5
Step-by-step explanation:
A: (-1,-7) and B: (9,1)
Slope: (-7-1)/(-1-9) = -8/-10 = 4/5
Slope: 4/5. Point (9,1)
y-1 = 4/5 (x-9)
y-1 = 4/5x - 36/5
y = 4/5x - 36/5 + 1
y = 4/5x - 31/5
Perpendicular bisector = Y = - 5/4x - 31/5

22. Jesse's fish hook was 12 feet below the top of the water. He let out
some of his line, and the hook sunk another 3 feet. What is the depth of the
fish hook now? Write an addition problem, and then give the answer.
9514 1404 393
Answer:
15 ft below the top of the water
Step-by-step explanation:
We can let distances "below the top of the water" be represented by negative numbers. Then the initial height of Jesse's hook was -12 ft. Adding line allowed his hook to sink further:
-12 +(-3) = -15
The depth of Jesse's hook now is 15 feet below the water surface.

(EASY) In a rectangle, the length is 5 metres more than the width The perimeter of the rectangle is 70 metres Calculate the measurments for the length and width
Answer:
15 m and 20 m
Step-by-step explanation:
Let the width be x
Length = x + 5
Perimeter = 2(l + b)
70 = 2(x + 5 + x)
70/2 = 2x + 5
35 = 2x + 5
35 - 5 = 2x
30 = 2x
30/2 = x
15 = x
Length = x + 5 = 20 m
Breadth = x = 15 m

Answer:
The first box (upper left corner)
Step-by-step explanation:
Since the y-intercept is 1/4 (you can find this where x = 0), in slope intercept the second number must equal the y-intercept.
Example:
y = 3x + 2 (0,2) is the y-intercept.
Therefore, the second number must equal 1/4 which the first box is correct.
(Negative 1/4 multiplied by -1 equals positive 1/4)
Triangle ABC is a right triangle. What is the length of AC?
Answer:
AC = [tex]\sqrt{58}[/tex]
Step-by-step explanation:
Calculate AC using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )
AC = [tex]\sqrt{(3-0)^2+(5-(-2)})^2[/tex]
= [tex]\sqrt{3^2+(5+2)^2}[/tex]
= [tex]\sqrt{9+7^2}[/tex]
= [tex]\sqrt{9+49}[/tex]
