Answer:

The value of A is -4, and that of B is -10

Step-by-step explanation:

We must carry out the indicated multiplication (and removal of parentheses) according to Order of Operations rules:

6x - 15 - 4x - 1 + 6 - 10x + 4x

Grouping like terms together, we get:

6x - 4x - 10 x + 4x  -  15  -1 +    6

this, in turn, simplifies to:

-4x-10

The value of A is -4, and that of B is -10

64 softballs

Step-by-step explanation:

Coach Beard currently already has 24 softballs.

When she orders 2 more buckets with 20 in each, that's another 20 + 20 = 40 softballs added to the original 24. So, let's add these two numbers:

24 + 40 = 64

The answer is 64 softballs.

Answer:Corresponding parts:

Angles, sides, or vertices of two or more figures that are located in the same position when the figures are aligned.

The term corresponding means that the parts of two or more figures match when turning, flipping or sliding them. In Figure 1, If we turn the object in green  a certain angle, we will get to match both the sided and the angles of these two objects. Therefore, object in red and object in green are corresponding.

Step-by-step explanation:

The domain is all possible values for x.

[tex]y=4\sqrt{4x+2}[/tex]

There are restrictions on the value of x.

A square root of a negative number is undefined.

The number in the square root has to be equal to 0 or be greater than 0.

Step-by-step explanation:

For 9 to be a common factor, x must be a multiple of 9. For the greatest common factor to be 9, not 18 or 36, x must be an odd multiple of 9.

There are 5 2-digit odd multiples of 9:

There are 5 possible 2-digit values for x.

Answer:

1814400 ways

Step-by-step explanation:

From the question, since it doesn't matter which seat you sit in as long as the neighbors either side of you still remain in the same order, thus;

Number of possible seat arrangements = 10! = 3628800

Now, we know that two seatings are the same when each person has the same two neighbors to the right or left. This simply means that it will be considered the same if the seats are placed around the circular table either clockwise or counter clockwise. With respect to this condition, we have to divide the number of possible seat arrangements by 2.

Thus;

Number of possible ways with the condition in the question = 3628800/2 = 1814400 ways

Simplify the numerator and denominator first:

5/8 + 3/4 = 11/8

-2/3 - 5/6 = -3/2

Now you have 11/8 / -3/2

When dividing two fractions change division to multiplication and flip the second fraction over:

11/8 x -2/3 = 11 x -2 / 8 x 3 = -22/24

-22/24 reduces to -11/12

The answer is -11/12

Step-by-step explanation:

[tex]5h+2\left(11-h\right)=-5\\\mathrm{Expand\:}5h+2\left(11-h\right):\quad 3h+22\\\\3h+22=-5\\\\\mathrm{Subtract\:}22\mathrm{\:from\:both\:sides}\\\\3h+22-22=-5-22\\\\Simplify\\\\3h=-27\\\\\mathrm{Divide\:both\:sides\:by\:}3\\\\\frac{3h}{3}=\frac{-27}{3}\\\\h=-9[/tex]

The value of h is -9.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

5h + 2 (11 - h) = - 5

Remove the parenthesis.

5h + 2 x 11 - 2h = -5

5h + 22 - 2h = -5

Subtract the like terms.

3h + 22 = -5

Subtract 22 on both sides.

3h = - 5 - 22

3h = -27

Divide both sides with 3.

h = -9

Thus,

The value of h is -9.

Answer:

Step-by-step explanation:

1. The last step claims the lengths PQ and RQ are the same based on the congruence of triangles SQR and TQP. In order to make that claim, some step in the proof needs to claim that those triangles are congruent. That claim is the missing step:

2. Without a claim of triangle congruence, the claim of triangle side congruence is unsupported. The proof must contain a claim that the triangles containing corresponding sides PQ and RQ are congruent.

Step-by-step explanation:

A function assigns the values. The equation for each reflected graph of f(x)=x²-4 can be written as shown below.

A function assigns the value of each element of one set to the other specific element of another set.

A.) Reflect across the y-axis, to find the equation replace x with -x,

f(-x) = (-x)² - 4

       = x² - 4

No, Change because the function is symmetrical about the y-axis

B.) Reflect across the x-axis, to find the equation replace y with -y,

y = f(x) = y

-y = -f(x)

   = -(x² - 4)

   = -x² + 4

Answer:

Step-by-step explanation:

On a given day , a particular raccoon will eat the trash from one of three different houses.

Let assume [tex]Y_n[/tex] be a random variable that illustrating  the house raccoon will eat on an unknown given nth day.

If he eats from the trash of a particular house, he has a 50% chance to eat from the same house the next day, and a 25% chance each to eat from one of the other two houses.

There are three states given in the above statement.

So, we can have state 1, state 2 and state 3

Assuming that:

state 1 = house 1

state 2 = house 2

state 3 = house 2

If he eats from the trash of a particular house,

For state 1 : he has a 50% chance to eat from the same house the next day

i.e state 1 = 0.50

and a 25% chance each to eat from one of the other two houses.

For state 2 and state 3: = 0.25

i.e state 2 = 0.25

state 3 = 0.25

NOW:

[tex]\mathtt{P[Y_{n+1 }= 0 \ | \ Y_n = 0] = 0.5}[/tex]

[tex]\mathtt{P[Y_{n+1 }= 1 \ | \ Y_n = 0] = 0.25}[/tex]

Answer:

<A=42°

Step-by-step explanation:

If the exterior of angle C is 126, the interior is 54.

The sum of the other two angles must be 126. (Exterior Angle Theorem)

If B is twice A, we divide 126 into thirds. This is 42.

So A is 42, B is 84, and C is 54.

Answer:

42°

Step-by-step explanation:

An exterior angle is equal to the sum of the opposite interior angles.

A + B = 126

The measure of B is twice the measure of A.

B = 2A

Substitute:

A + 2A = 126

3A = 126

A = 42

Answer:

18 square units

Step-by-step explanation:

A square has the following vertices

(−7, −5), (−4, −2), (−4, −8), (−1, −5)

To determine if the are we look for the length of just one of it's sides, because it's a square,all of it's side are equal.

And the are is determined by squaring one of it's sides.

An attachment of the figure is given below to help us know the vertices to use to determine the length.

Length= √ ((-4-(-7))²+(-2-(-5))²)

Length= √((3)²+(3)²)

Length= √(9+9)

Length= √18

So area is the square of the length

Area= (√18)²

Answer:

(a) The critical value of t at P = 0.01 and 15 degrees of freedom is 2.602.

(b) The critical value of t at P = 0.05 and 19 degrees of freedom is -1.729.

(c) The critical value of t at P = 0.025 and 12 degrees of freedom is -2.179 and 2.179.

Step-by-step explanation:

We have to find the critical t values for each of the following levels of significance and sample sizes given below.

As we know that in the t table there are two columns. The horizontal column is represented by the symbol P which represents the level of significance and the vertical column is represented by the symbol '[tex]\nu[/tex]' which represents the degrees of freedom.

(a) A right-tailed test of a population mean at the α=0.01 level of significance with 15 degrees of freedom.

So, here the level of significance = 0.01

And the degrees of freedom = n - 1  = 15

Now, in the t table, the critical value of t at P = 0.01 and 15 degrees of freedom is 2.602.

(b) A left-tailed test of a population mean at the α=0.05 level of significance with a sample size of n = 20.

So, here the level of significance = 0.05

And the degrees of freedom = n - 1  

                                                = 20 - 1 = 19

Now, in the t table, the critical value of t at P = 0.05 and 19 degrees of freedom is -1.729.

(c) A two-tailed test of a population mean at the α=0.05 level of significance with a sample size of n = 13.

So, here the level of significance = [tex]\frac{0.05}{2}[/tex] = 0.025 {for the two-tailed test}

And the degrees of freedom = n - 1  

                                                = 13 - 1 = 12

Now, in the t table, the critical value of t at P = 0.025 and 12 degrees of freedom is -2.179 and 2.179.

Answer:

C.

Step-by-step explanation:

Step 1: Isolate [tex]V_{0}[/tex]

Multiple t on both sides

at = [tex]V_{1} -V_{0}[/tex]

Subtract [tex]V_{1}[/tex] on both sides

[tex]at - V_{1} = V_{0}[/tex]

Therefore the answer is C
