There were 325 adult tickets sold that day student had 388 tickets

So, total no. of tickets = 713

Let the no. of tickets sold to adults be x

Then the no. of tickets sold to student = x + 63

Now, we have the equation as

⇒ x + x + 63 = 713

⇒ 2x = 713 - 63

⇒ 2x = 650

⇒ x = 650/2

⇒ x = 325 tickets

An equals symbol (=) is fundamental in equations. You can think of an equation as having a left-hand side and a right-hand side as there will be a mathematical expression on either side.

Imagine a set of scales to represent an equation. To solve it, each side must be balanced, even if you place different amounts on the left or right.

There is always an unknown in an algebraic equation. A symbol, such as x, y, or z, is used to symbolize this.

The given equation 1/2 ( 2p + 9 ) = p + 5 has no solution.

Whenever the two lines are parallel, a system of 2 linear equations in two variables has no solution.

As for the given question;

The expression is given as;

1/2 ( 2p + 9 ) = p + 5

Simplifying the equation;

(1/2)×2p + (1/2)×9 = p + 5

p + 9/2 = p + 5

As, the variable 'p is getting cancelled on the both side.

The expression given no solution.

Therefore, the stated linear equation in one variable 1/2 ( 2p + 9 ) = p + 5 does not posses any solution.

The brand of sand chosen by Alisa is Sand A with a total cost of $10,816, instead of Sand B with a total cost of $11,267.

The total costs are determined using mathematical operations and unit conversions.

Firstly, the volume of the court is calculated, using  V = l x w x h.  The result is converted from cubic feet to pounds at  1 ft³ = 100 lb.

After the conversion, the rest of the calculations carried on the mathematical operations of addition, division, and multiplication.

The length of the volleyball court = 52 feet

The width of the volleyball court = 26 feet

The height of the volleyball court = 1 feet

The volume, V = l x w x h

= 52 x 26 x 1

= 1,352 feet³

1 ft³ = 100 lb

1,352 feet³ = 135,200 lb (1,352 feet³ x 100)

Sand A's Cost = $12 per 150 lb

135,200 lb = $10,816 ($12 x 135,200/150)

Sand B's Cost = $5 per 60 lb

135,200 lb = $11,267 ($5 x 135,200/60)

Thus, Sand A, most likely chosen by Alisa, is more cost-effective than Sand B.

Answer:

x = 8

Step-by-step explanation:

Since both pools are similar, it follows that their side lengths are proportional.

Therefore:

[tex] \frac{BC}{FG} = \frac{AD}{EH} [/tex]

BC = 4

FG = 3

AD = x

EH = 6

Plug in the values

[tex] \frac{4}{3} = \frac{x}{6} [/tex]

Multiply both sides by 6

[tex] \frac{4}{3}*6 = \frac{x}{6}*6 [/tex]

[tex] \frac{24}{3} = x [/tex]

The ratio of the difference in outputs to the input interval is constant and equal to -8. This indicates that the function is a linear function with a slope of -8.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To find the differences of outputs for different input intervals, we can use the given function and the values in the table.

(a) The inputs that are 1 unit apart are -1 and 0. The corresponding outputs are f(-1) = -3 and f(0) = -11. The difference in outputs is:

f(0) - f(-1) = (-11) - (-3) = -8

Therefore, the difference of outputs of any two inputs that are 1 unit apart is -8.

(b) The inputs that are 2 units apart are -2 and 0. The corresponding outputs are f(-2) = 5 and f(0) = -11. The difference in outputs is:

f(0) - f(-2) = (-11) - 5 = -16

Therefore, the difference of outputs of any two inputs that are 2 units apart is -16.

(c) The inputs that are 3 units apart are -3 and 0. The corresponding outputs are f(-3) = 13 and f(0) = -11. The difference in outputs is:

f(0) - f(-3) = (-11) - 13 = -24

Therefore, the difference of outputs of any two inputs that are 3 units apart is -24.

(d) We can observe that the ratios of the differences in the outputs to the input intervals are constant, indicating that the function is linear. For example:

The ratio of the difference in outputs for inputs that are 1 unit apart to the input interval is:

-8 / (0 - (-1)) = -8 / 1 = -8

The ratio of the difference in outputs for inputs that are 2 units apart to the input interval is:

-16 / (0 - (-2)) = -16 / 2 = -8

The ratio of the difference in outputs for inputs that are 3 units apart to the input interval is:

-24 / (0 - (-3)) = -24 / 3 = -8

Therefore, the ratio of the difference in outputs to the input interval is constant and equal to -8. This indicates that the function is a linear function with a slope of -8.

Step-by-step explanation:

Always remember the order of operations: PEMDAS.

7 - (3 + 5) + (-3 + 6)/3 x 5

7 - (8) + (3)/3 x 5 (solve the parantheses first)

7 - 8 + 1 x 5 (3/3 comes first since multiplication and division have the same order; you would go left to right)

7 - 8 + 5 (Multiplication has a higher order than addition and subtraction)

Step-by-step explanation:

We need to know about quadratic equation to solve this problem. The other three consecutive odd integers that satisfy the conditions are 11, 13 and 15.

We need to consider three consecutive odd integers, odd integers are integers that are not divisible by 2. Odd and even integers occur alternately so the the difference between two consecutive odd integers is always 2. We will consider one odd integer x, the next odd iinteger will be x+2 and the third odd integer will be x+4. Therefore we have our three consecutive odd integers, x, x+2 and x+4. It is said that the square of the third integer is 65 less than the sum of the squares of the first two. We can write this relation as

[tex](x+4)^{2} +65=x^{2} +(x+2)^{2}[/tex]

We can solve this equation to get a quadratic equation, and then solve it for x

[tex]x^{2} +8x+16+65=x^{2} +x^{2} +4x+4\\x^{2} +4x-8x+4-16-65=0\\x^{2} -4x-77=0[/tex]

We will solve the above quadratic equation for x

[tex]x^{2} -4x-77=0\\x^{2} +7x-11x-77=0\\x(x+7)-11(x+7)=0\\(x+7)(x-11)=0\\[/tex]

Therefore we get two values for x -7 and 11, from the question we already know about -7, we will find the three odd integers from 11 now

So the other three consecutive odd integers that satisfy the given conditions are 11,13 and 15.

Answer:

b. Normal data is never one of the inference assumptions.

Step-by-step explanation:

A categorical data specifies among two or more groups, which one each observation belongs to, and one or more explanatory variables that can be used to predict this membership.

So, there are two propositions in statistical inference for categorical data

1. That each data in a cell is independent of the others.

2. That samples are randomly drawn.

Thus, there is no room for normality.

Step-by-step explanation:

r^3 cancels out r in the denominator remaining with r^2 in the numerator.

so 3r^2/2

= 3r^2 /2

Answer:

solving the expression [tex]\frac{3r^3}{2r}[/tex] we get [tex]\mathbf{\frac{3}{2}r^2}[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\frac{3r^3}{2r}[/tex]

For solving exponents in the fraction we can use the exponent rule:[tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

Applying the above rule and solving:

[tex]\frac{3r^3}{2r}\\=\frac{3}{2}r^{3-1}\\\\=\frac{3}{2}r^2[/tex]

So, solving the expression [tex]\frac{3r^3}{2r}[/tex] we get [tex]\mathbf{\frac{3}{2}r^2}[/tex]
