a loaf of bread has 12 slice. micky ate 1/4 of the loaf. write the fraction of the loaf micky ate in twelfths

Answer:

2/3

(-4, 2) and (-16, -6)

slope = m = (y2 - y1) / (x2 - x1) = (-6 - 2) / (-16 - -4) = -8 / -12 = 2 / 3 = 0.667

Answer:

Option C

Step-by-step explanation:

System of equations have been given as,

y - 4x = 16

y = 4x + 16 ------(1)

By comparing with slope-intercept form of the linear equation,

y = mx + b

Here, m = slope of the line

b = y-intercept

Therefore, m₁ = 4

2y = 8x + 16

y = 4x + 8 -------(2)

Slope of the line m₂ = 4

m₁ = m₂

Therefore, both the lines are parallel and both will not intersect each other.

Hence, there will be no solution of the system of equations.

Option C will be the correct option.

Step-by-step explanation:

Answer:

0.9945 = 99.45% probability that the student answers at most four questions correctly

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student answers correctly, or he/she does not. The probability of the student answering a question correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A quiz consists of six multiple choice questions.

This means that [tex]n = 6[/tex]

Each question has four choices. Student guesses randomly.

This means that [tex]p = \frac{1}{4}[/tex]

What is the probability that the student answers at most four questions correctly?

This is:

[tex]P(X \leq 4) = 1 - P(X > 4)[/tex]

In which

[tex]P(X > 4) = P(X = 5) + P(X = 6)[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{6,5}.(0.25)^{5}.(0.75)^{1} = 0.0053[/tex]

[tex]P(X = 6) = C_{6,6}.(0.25)^{6}.(0.75)^{0} = 0.0002[/tex]

[tex]P(X > 4) = P(X = 5) + P(X = 6) = 0.0053 + 0.0002 = 0.0055[/tex]

[tex]P(X \leq 4) = 1 - P(X > 4) = 1 - 0.0055 = 0.9945[/tex]

0.9945 = 99.45% probability that the student answers at most four questions correctly

Answer:

  x = (A -40)/7

Step-by-step explanation:

Maybe you want to solve for x.

  A = 7x +40 . . . . . given

  A -40 = 7x . . . . . subtract 40

  (A -40)/7 = x . . . divide by 7

The value of x will be ...

  x = (A -40)/7

-90 + x = 180

Step 2: Solve for x

Answer:

x = 270

Step-by-step explanation:

- 90 + x = 180

Add 90 to each side of the equation.

- 90 + 90 + x = 180 + 90

Combine like terms.

x = 270

Answer:the answer is ABC

Step-by-step explanation:

I had this on my exit ticket and my teacher reviewed the question and told me it was correct

Answer:

B. 8 x 12

Step-by-step explanation:

First of all, it has an area of 96

So lets find the multiplication pair that equals 96.

10 x 10 = 100        NO

6 x 16 = 96           YES

8 x 12 = 96           YES

Now we have two equations: 8 x 12 and 6 x 16

Perimeter of 40 means:

2(a+b) = 40

Lets input the two equations:

2(8+12) = 2 x 20 = 40

2(6+16) = 2 x 22 = 44

So the dimensions that works is 8 x 12

Answer:

a. F = 26214.4π lb/ft-s²∫₋₁₀⁰(y + 10)dy

b. W = 104857.6π lb-ft/s²∫₋₁₀⁰(y + 10).dy

Step-by-step explanation:

(a) Write down an integral for the total fluid force on the side of the tank.

We know force, F = ∫PdA where P = pressure and dA = differential area element in tank surface.

Let the position of the bottom of the tank be y = -h where h = height of tank and y = 0 be the top of the tank. So, the height of any point y of the tank H is y - (-h) = y + h = y + 10

The pressure P = ρgH where ρ = density of oil in tank = 51.2 lb/ft³ and g = acceleration due to gravity = 32 ft/s²

P = ρgH

P = ρg(y + 10)

The differential area element of a point on the side of the tank is dA = 2πrdy

So, F = ∫PdA

F = ∫ρg(y + 10)2πrdy

we integrate y from y = -h = -10 to y = 0

So, F = ∫₋₁₀⁰ρg(y + 10)2πrdy

F = ∫₋₁₀⁰2πrρg(y + 10)dy

F = ∫₋₁₀⁰2π(8 ft)(51.2 lb/ft³)(32 ft/s²)(y + 10)dy

F = ∫₋₁₀⁰26214.4π lb/ft-s²(y + 10)dy

F = 26214.4π lb/ft-s²∫₋₁₀⁰(y + 10)dy

(b) Suppose all the kerosene is pumped to ground level. Write down an integral for the work required to pump the oil.

The work done W = ∫F.dy

W = ∫F.dy

F = ρgV where V = volume of tank = πr²H = πr²(y + 10)

F = ρgπr²(y + 10)

So, W = ∫F.dy

W = ∫ρgπr²(y + 10).dy

Since the water is pumped to ground level, we integrate y from y = -h = -10 to y = 0

W = ∫₋₁₀⁰ρgπr²(y + 10).dy

W = ∫₋₁₀⁰π(51.2 lb/ft³)(32 ft/s²)(8 ft)²(y + 10).dy

W = ∫₋₁₀⁰104857.6π lb-ft/s²(y + 10).dy

W = 104857.6π lb-ft/s²∫₋₁₀⁰(y + 10).dy

HOPE THIS HELPS AND HAVE A VERY GOOD DAY

Answer:

Step-by-step explanation:

Let's solve for a .

[tex]5a+6b=18[/tex]

Step 1: Add -6b to both sides.

[tex]5a+6b+−6b=18+−6b[/tex]

[tex]5a=−6b+18[/tex]

Step 2: Divide both sides by 5.

Let's solve for b.

[tex]5a+6b=18[/tex]

Step 1: Add -5a to both sides.

[tex]5a+6b+−5a=18+−5a[/tex]

[tex]6b=−5a+18[/tex]

Step 2: Divide both sides by 6.
