Answer:

q = p + r + 3s

Step-by-step explanation:

q - r - 3s = p solve for q

q - r - 3s = p

add r to both sides:

q - r - 3s + r = p + r

q - 3s = p + r

add 3s to both sides:

q - 3s + 3s = p + r + 3s

q = p + r + 3s

The number of ounces of meat were used is 52 ounces.

Given that, a sandwich shop serves 4 ounces of meat and 3 ounces of cheese on each sandwich.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

There are 7 ounces of combined meat and cheese in each sandwich (4+3 =7)

Number of sandwiches can make with 91 ounce of meat and cheese

= 91/7

= 13 sandwiches

Number of ounces of meat = 13 × 4 = 52 ounces

Number of ounces of cheese = 13 × 3 = 39 ounces

Therefore, the number of ounces of meat were used is 52 ounces.

Answer: 6 5/12

Step-by-step explanation: You could do 3x4 = 12

so, 2x4 = 8, also 3x3 = 9 which would be 4 8/12 + 1 9/12, then just add.

Answer:

6 5/12

Step-by-step explanation:

We can first begin by separating the whole number and the fraction:
4 + 2/3 + 1 + 3/4

After reordering, it becomes:

4 + 1 + 2/3 + 3/4
5 + 2/3 + 3/4

Now, we must find the common denominator for the fractions so that we may add them:
The common denominator is 12.
5 + 2(4)/3(4) + 3(3)/4(3)

5 + 8/12 + 9/12

5 + 17/12

Simplifying the improper fraction gives us:

5 + 1 + 5/12

And the final answer is:

6 + 5/12

6 5/12

The largest possible whole-number length for the third side of the triangle is 23.

The total of any two sides in a triangle with sides a, b, and c MUST be less than the length of the third side.  

You have a line segment, not a triangle if the third side's length equals the sum of the other two sides' lengths.  

Here, the sum of the two sides of the triangle is 12 + 12 = 24.  

Therefore, the length of the third side should be less than 24, and the whole number which is less than 24 is 23.  

Hence, the length of the third side is 23.

Mei Mei's age if the sum of Mei Mei's age and 5 times Xin's age is 143. is 23 years.

Let the ages be x and x+1 since they're consecutive numbers.

In this case the sum of Mei Mei's age and 5 times Xin's age is 143. This will be:

x + 5(x + 1) = 143

x + 5x + 5 = 143

Collect like terms

6x + 5 = 143

6x = 143 - 5

6x = 138

Divide

x = 138 / 6

x= 23

Length of the resulting box will be of (16-x) inches

A rectangle can be made into a cuboid by cutting squares of equal length from each corners and then joining the edges.

Given, length of cardboard= 16inches

Width of cardboard= 12 inches

If squares of side x is cut out of the corners and the sides are bent  upwards to make a box,

The dimensions of the resulting box will be,

Length= (16-x) inches

Width= (12-x) inches

The equation of the polynomial equation is P(x) = (x + 2)(x + 4)(x - 3)(x + 3)

The given parameters are

Leading coefficient = 1

Zeros =  − 2 , − 4 , 3 , and 3 .

Polynomial equations have their multiplicities to add up to their degree.

This means that the multiplicity of the zeros is 1

The equation of the polynomial is then calculated as

P(x) = (x - zero)^ multiplicity

So, we have

P(x) = (x + 2)(x + 4)(x - 3)(x + 3)

From the question, the polynomial is to be factored

This means that we represent it as

Polynomial is an expression consisting of indeterminates and coefficients the factored form of polynomial function is (x+2)(x+4)(x-3)(x-3)

Polynomial is an expression consisting of indeterminates and coefficients, which involves  the operations like addition, subtraction, multiplication, and positive-integer powers of variables

Factors are the numbers which divide the expression or number with a remainder zero.

We need to write the factored form of the polynomial functions with real; coefficients and zeros minus two comma  minus four comma three and 3.

The leading coefficient of the polynomial is 1. Leading coefficient means coefficient of leading term.

Zeros =  − 2 , − 4 , 3 , and 3 .

Let the polynomial is of variable x.

The equation of the polynomial is then calculated as

P(x) = (x - zero)^ multiplicity

(x-(-2))=x+2

(x-(-4))=x+4

(x-3)=x-3

So the factored form is (x+2)(x+4)(x-3)(x-3)

the polynomial is P(x)=(x+2)(x+4)(x-3)(x-3)

Hence the factored form of polynomial function is (x+2)(x+4)(x-3)(x-3).

A function is called bijective if it is one-to-one and onto.

To check one to one, let x1 = x2 , where x1, x2 belongs to R.

Given the condition that x1 and x2 are not equal to 2. So, the above equation implies that

So, it is a one-to-one function.

For onto function, let y= (3x + 4) / (x-2). Now, interchange x and y, and solve the equation fo y:

Here, the domain of the inverse of the function is R - {3}. But the function is R - {2} => R. So, it is not onto.

The second graph (B: X?)

Step-by-step explanation:

The second graph (B?) is a function because the graphed line passes the vertical line test (no two points are vertically on top of each other).

The values of g(x) at x = 1, 2 and 3 are 2, 8 and 14 respectively.

Which table contains the values of g(x)?

Since f(x) = 3x - 4 and g(x) = f(2x)

so, in f(x) = 3x - 4, we can replace x with 2x:  

g(x) = f(2x) = 3(2x) - 4 = 6x - 4

when x = 1:

g(x) = 6(1) - 4

      = 6 - 4 = 2

when x = 2:

g(x) = 6(2) - 4

      = 12 -  4 = 8

when x = 3:

g(x) = 6(3) - 4

      = 18 -  4 = 14

Therefore, when x = 1, 2 and 3, their corresponding values of g(x) are 2, 8 and 14.  So 4th table contains the values of g(x).

The p-value, used in null-hypothesis significance testing, represents the likelihood that the test findings will be at least as extreme as the result actually observed, assuming that the null hypothesis is true.

Therefore, the p-value for study b exists 0.080.

The P value is the likelihood, for a particular statistical model, that the statistical summary would be either equal to or more extreme than the actual observed results if the null hypothesis were to hold.

In a two tailed test the probability of occurrence exists the total area beneath the critical range of values on both the sides of the curve (negative side and positive side)

Therefore, the probability values for a two tailed test as compared to a one tailed test exists given by the under given relation -

simplifying the above equation, we get

[tex]$P \frac{\alpha}{2}=0.040$[/tex]

Substituting the given value in above equation, we get -

Probability values for a two tailed test
