Answer:
We draw two balls. We know that one of them is orange.
Let's suppose that the first one is the orange.
Then after drawing that, we know that there are 5 balls left in the urn, and only one will be orange.
Then the probability of drawing the other orange ball is equal to the quotient between the number of orange balls and the total number of balls.
P1 = 1/5.
And now let's consider the other case, where we know that in the second draw we will draw an orange ball.
Then the probability of drawing an orange ball in the first draw is equal to the quotient between the number of orange balls (at the beginning we have 2) and the total number of balls (6)
P2 = 2/6
As those represent different cases (we assume different conditions for each one), the probability that we draw two orange balls, knowing for sure that we will draw one, is equal to the sum of these probabilities.
P = P1 + P2 = 1/5 + 2/6 = 6/30 + 10/30 = 16/30 = 8/15

Jim’s backyard is rectangular with dimensions of 75 feet by 120 feet. He is planning to designate part of the yard to plant a vegetable garden. The garden will be a similar rectangle, using a scale factor of 2/5. How much fencing will he need if he wants to enclose the garden on all four sides?
Answer:
He will need 99 feet of fence.
Step-by-step explanation:
Jim's back yard has the following dimensions;
Length=120 feet
Width=75 feet
The gardens dimensions can be calculated using the expression;
Length of garden=Length of back yard/scale factor
where;
Length of back yard=120 feet
Scale factor=2/5
replacing;
Length of garden=120/2/5
Length of garden=12 feet
Width of garden=Width of back yard/scale factor
where;
Width of back yard=75 feet
Scale factor=2/5
replacing;
Width of garden=75/2/5
Width of garden=37.5 feet
The gardens dimension are;
Garden width=37.5 feet
Garden length=12 feet
To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;
Perimeter=2(length+width)
Perimeter=2(12+37.5)=99 feet
He will need 99 feet of fence
Answer:
he will need 99 feet to fence
Step-by-step explanation:
Jim's back yard has the following dimensions;
Length=120 feet
Width=75 feet
The gardens dimensions can be calculated using the expression;
Length of garden=Length of back yard/scale factor
where;
Length of back yard=120 feet
Scale factor=2/5
replacing;
Length of garden=120/2/5
Length of garden=12 feet
Width of garden=Width of back yard/scale factor
where;
Width of back yard=75 feet
Scale factor=2/5
replacing;
Width of garden=75/2/5
Width of garden=37.5 feet
The gardens dimension are;
Garden width=37.5 feet
Garden length=12 feet
To get the length of the fence that will enclose all four sides, we calculate the perimeter of the garden;
Perimeter=2(length+width)
Perimeter=2(12+37.5)=99 feet
He will need 99 feet of fence

Solve for z. –z + 4= -4
Answer:
-z+4=-4
Step-by-step explanation:
First, you want to move the positive four to the other side to isolate the variable.
-z=-8
You cannot have a negative variable, so divide both sides by 1.
-z/1=-8/1
Your answer would be:
Z=8

Answer:
16: y=4x+14 17: 12 18: when you simplify it all individually you get x=3 for both equations. 19: $6.69
Step-by-step explanation:
16:y-2=4(x+3) distribute 4 and get y-2=4x-12. Add 2 to both sides to get y-4x+14.
17:x+2y=4 and 3x+6y=? divide 3x+6y by three and you get x+2y=4. This means you can just multiply the 4 by 3 to get the answer.
18:3x-5=4 and 3x-3=6. For the first one add 5 to both sides to get 3x=9 then divide both side by 3 to get x=3. For the second one add 3 to both sides to get 3x=9. Again divide both sides by three to get x=3.
19: $18-$4.62=13.38 since he wants 2 models divide 13.38 by 2 to get 6.69.
Use the Remainder Theorem to find the
remainder when dividing f(x) = 4x^3 - 2x^2 + 7x - 1
by x - 1.
Answer:
f(1) = 8
Step-by-step explanation:
x - 1 = 0
x = 1
f(x) = 2x² + 7x - 1
f(1) = 2*1² + 7*1 - 1
= 2 + 7 - 1
= 9 - 1
f(1) = 8

Answer: Choice A) [tex]-\infty < x < \infty[/tex]
We can plug in any x value we want. The domain is the set of all real numbers. We don't have to worry about applying the square root of a negative value since negative values are allowed in cube roots.
For instance, [tex]\sqrt[3]{-64} = \sqrt[3]{(-4)^3} = -4[/tex]

If TUV is isosceles, find the value of X
Answer:
x = 17
Step-by-step explanation:
Since the triangle is isoceles that means angle UTV is also 43 degrees. The sum of all angles in a triangle is 180 degrees. So construct this equation. 43 + 43 + 43 + 8x - 42 = 180. Now solve for x.
