Answer:

the 2nd one

Step-by-step explanation:

Answer:

x=-1, y=-5 ---> (-1, -5)

Step-by-step explanation:

so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of   4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)

The solution for equations y=-4x-9 and y=-4x-9  is x=-1, y=-5.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equations are,

y=-4x-9       (1)

4x-y=1        (2)

From equation (1), substitute the value of y in equation (2)

4x-(-4x-9)=1

8x+9=1

8x=-8

x=-1

Substitute x=-1 in equation (1),

y=-4(-1)-9

y=4-9

y=-5

The value of x is -1 and y is -5

Answer: 12 stones

Step-by-step explanation:

The side of the length will be x = √m square inches.

The area of the square and rectangle is -

Square = [x]²           {x is the side of a square]

Rectangle = L x B    {L is the length and B is breadth}

here, we have,

Given is Lisa who is decorating outside edge of a square picture frame. She needs to know the side length of the frame. The area of the frame is [m] square inches.

It is given that the the area of the square is [m] square inches.

Assume that the length of the side is [x] inches.

x² = m

x = ±√m

Side cannot be negative.

Therefore, the side of the length will be -  x = √m

Therefore, the side of the length will be x = √m square inches.

Answer:

41.67% probability that a student has a dog given that they have a cat

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: having a cat.

Event B: having a dog.

12 of 27 students have a cat:

This means that [tex]P(A) = \frac{12}{27}[/tex]

5 students who have a cat and a dog.

This means that [tex]P(A \cap B) = \frac{5}{27}[/tex]

What is the probability that a student has a dog given that they have a cat?

[tex]P(B|A) = \frac{\frac{5}{27}}{\frac{12}{27}} = \frac{5}{12} = 0.4167[/tex]

41.67% probability that a student has a dog given that they have a cat

Step 1) Divide the figure into shapes

Large rectangle: 5 x 12

Smaller rectangle: 4 x 6

Square: 2 x 2

Triangle: 4 x 3

Step 2) Find the area of each shapes

Large rectangle: A = 5 x 12 = 60

Smaller rectangle: A = 4 x 6 = 24

Square: A = 2 x 2 = 4

Triangle: A = 1/2 x 4 x 3 = 6

Step 3) Add all of the areas together

A = 60 + 24 + 4 + 6 = 94 square miles

HOPE IT WILL BE HELPFUL FOR U

Answer:

When you have multiple events (here each flip of the coin is a individual event) the probability of all the events (or the joint probability) is equal to the product of the probabilities of each event.

For example, with a fair coin the probability of getting heads is 0.50

If you get heads 3 times, and you add the probabilities you get:

0-50*3 = 1.50

this has no sense, because the probability must be a number between 0 and 1.

The actual probability is:

P = 0.50*050*0.50 = 0.125

Answer:

No.

Step-by-step explanation:

For figures to be similar, they must have proportional sides.

In other words, we can take a number and use it to scale all the sides.

The small rectangle has a 5 on the bottom side, while the big rectangle has a 15 on the bottom side. The scale factor is 3.

The small rectangle has a 3 on the right side, while the big rectangle has a 6 on the right side. The scale factor is 2.

As the scale factors are not equivalent, the figures are not similar.

Answer:

x + 10 = 24

Step-by-step explanation:

In the figure attached,

There are two external points A and B.

Fro point A two tangents AD and AE have been drawn and From point B tangents BE and BC have been drawn.

Since AD = 10 units,

Therefore, AE = 10 units

(Since tangents drawn from a point to a circle are same in measure, therefore, AD = AE)

Therefore,

BE = AB - AE

Since BE = BC

So BC = AB - AE

       x = 24 - 10

x + 10 = 24

Therefore, (x + 10) = 24 will be the equation to be used to solve for x.

Step-by-step explanation:

A statistical question has variability in the answer, so,

A=could range from any numbers providing a wide range of results

B=it's one answer (eg.5ft4) meaning a range can't be produced

C=could range from any food providing a wide range of results

D=One answer so no variations possible

E= could be a range of numbers

Answer:

288 students can be served

Step-by-step explanation:

Looking at the donation made by the ice cream parlor, we want to know the number of students to be served.

We need to achieve a consistency in units first. What I mean by this is that all our units must be the same.

The parlor donated 6 containers with each container holding 3 gallons. The amount donated is thus 3 * 6 = 18 gallons of ice cream

Mathematically, there are 16 cups in a gallon. Thus, the amount of cups donated by the parlor would be 16 * 18 = 288 cups

Now since 1 student takes 1 cup of ice cream, the number of students that the donation can serve is 288/1 = 288 students

0.38 is 7/18 (filling space)

Answer:

0.388888889

Step-by-step explanation:

The answer is false.

The square of 2.8 is actually 7.83999 or 7.84 if rounded.

To get this, we simply bring 2.8 to the power of 2.

2.8 x 2.8 = 7.8399

Therefore, the answer would be false since the actual square of 2.8 is 7.84

Answer:

_________________________

given

no. of student  went to the first school dance = 340

no. of student  went to the last school dance = 306

Percentage of change between two dance

= ((no. of student  went to the first school dance - no. of student  went to the last school dance)/ no. of student  went to the fist school dance)*100

= (340 - 306)/340 *100

= (36/340 )*100 = 10.59%

The percent of change between the two dances 10.59%.
