Answer:

neither is right

it should factorize to (8x + 12) (x + 1)

Answer:

a) (+) × (?) = (+)

(?) = (+)

b) (-) × (+) = ?

? = (-)

c) (?) × (-) = ?

? is undefined

Step-by-step explanation:

a) (+) × (?) = (+)

From the given equation in the question, by dividing both side of the equation by (+), we have;

((+) × (?))/(+) = (+)/(+)

(?) = (+)/(+) = (+)

Therefore, we have;

(+) × (+) = (+)

(?) = (+)

b) (-) × (+) = ?

From the given equation in the question we apply the operation rules as follows;

(-) × (-) = (+)

(-) × (+) = (-)

Therefore;

(-) × (+) = ? = (-)

? = (-)

c) (?) × (-) = ?

From the rules of multiplication, we have;

(-) × (-) = (+)

(+) × (-) = (-)

Therefore, when (?) = (-), ? = +, from which we have;

(?) ≠ ?, which is an error

Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign

Therefore, the equation, (?) × (-) = ?, is undefined.

Step-by-step explanation:

The probability of P(a or b) is 0.1248

Given the following probabilities

P(a) = 0.24

P(b) = 0.52

Independent events mean that each event can occur at different times.

P(a or b) = P(a) * P(b)

Substitute the given parameters into the formula;

P(a or b) = 0.24 * 0.52

P(a or b) = 0.1248

Hence the probability of P(a or b) is 0.1248

Answer:

Step-by-step explanation:

The standard deviation of T is equivalent to 5.

       [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]

Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.

We can write that -

5 = √∑(x{i} - 10)²/√3

√∑(x{i} - 10)² = 5√3

(√∑(x{i} - 10)²)² = (5√3)²

∑(x{i} - 10)² = 25 x 3

∑(x{i} - 10)² = 75

Now, we can write that -

σ = √(75/3)

σ = √25

σ = 5

Therefore, the standard deviation of T is equivalent to 5.

Answer:

We can solve this question using the slope equation which is y2-y1/x2-x1

If you use that formula and sub in the coordinates

-4 - 5 / -1-2

-9/-3

= 3

The slope should be 3/1

Answer:

m = 3

Step-by-step explanation:

Use slope formula

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

-4-5/-1-2 = 3

Answer:

x = 7

Step-by-step explanation:

all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last,  multiply 3 1/2 by 2 and you will geet 7 as your final answer.

The answer would be 7!

You would take 1 and add 1/2 to it

= 1 1/2

Then, multiply by 2

= 3

Then add 1/2 to that

= 3 1/2

Then multiply 2 one more time

= 7

This is because Mai gave half of her brownie and then half more of her brownie to each person she gave it to

So you would add 1 + 1/2 and then multiply by 2

Since she did this to 2 people you would repeat one more time!

Answer:

x+4 and y+3

Step-by-step explanation:

Both the x and y values move in positive directions from the first triangle to the second.

Answer:

(x+4, y+3)

Step-by-step explanation:

First, choose a point to follow (I chose C).  The coordinates of C are (-2, -5).  The coordinates of C' are (2, -2).  To get to 2 from -2, you have to add 4.  Move left or right because it's on the x-axis.  Since it's moving you the right, it is positive.  So, x+4 is the first part.  To get from C to C', you have to move up to follow the y-axis, meaning another positive.  Counting the units from (2, -5), because that is the point after x+4, there are 3 units.  So, (x+4, y+3).

Answer and Step-by-step explanation:

A. Cruz is correct.

B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.

[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]

Now that we have a positive number within the cube root, we can solve the cube root itself.

So what is the cube root of 64?

The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.

C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.

Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.

Answer:

(7, -4)

Step-by-step explanation:

The formula for calculating midpoint is expressed as;

M(X, Y) = (x2+x1)/2, (y1+y2)/2

X = x1+x2/2

Y = y1+y2/2

Given

X = 5, Y = 1, x1 = 3, y1 = 6

Get x2

X = x1+x2/2

5 = 3+x2/2

10 = 3+x2

x2 = 10-3

x2 = 7

Get y2;

Y = y1+y2/2

1 = 6+y2/2

2 = 6+y2

y2 = 2-6

y2 = -4

Hence the coordinate of B is at (7, -4)

Answer:

4t + 12 [tex]\leq[/tex] 80

Step-by-step explanation:

Set up an inequality where t is the cost of one ticket

Since her budget is $80, a less than or equal sign needs to be used.

4t will represent the total cost of the tickets, since she needs to buy 4. Add 12 to this to represent the parking cost:

4t + 12 [tex]\leq[/tex] 80 is the inequality.
