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!

Hope this helped!

Answer:

875 ft^3

Step-by-step explanation:

Pick them apart starting at the bottom. The formul used is V=lwh

Starting at the bottom we have we have a sqare of 5 ft = 5ft^3= V = 125 ft^3

Then we have a rectangular prism: 5 x 5 x 20 = V = 500 ft^3

Third we have 5 x 5 x 10 = V = 250 ft3

125+500+250 = 875 ft^3

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:

you don't have the graph

Step-by-step explanation:

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.

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:

Step-by-step explanation: B

The tables of ordered pairs representing relations that are functions are: A and C.

If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.

Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.

Therefore, table A and C represent functions.

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

Answer:

  8.6 cm

Step-by-step explanation:

We notice the hypotenuse is given, and the desired length is of the side opposite the given angle.

The mnemonic SOH CAH TOA reminds you of the relevant relationship:

  Sin = Opposite/Hypotenuse

  sin(35°) = x/(15 cm) . . . . . . fill in the given information

We can multiply by 15 cm to find the value of x.

  x = (15 cm)sin(35°)

  x ≈ 8.6

_____

For those inclined to copy this answer to a different question, we suggest ...

  y = (15 cm)cos(35°) ≈ 12.3 cm

Answer: 8.603646545 or rounded to the nearest tenth 8.6

Step-by-step explanation:

you are going to have to use (sin). so,

(15)sin(35)

8.603646545 or 8.6

this is correct.

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.

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.
