**Answer 2**

The mathematical **expression** of Ten times the **sum **of a number and 4 is 10(x + 4).

What is an expression?

**Expression **in maths is defined as the collection of numbers **variables **and **functions **by using signs like addition, subtraction, multiplication, and division.

The **Numbers **constants, variables, operations, **functions**, brackets, punctuation, and grouping can all be represented by **mathematical symbol**; that can also be used to indicate the logical syntax's order of **operations **and other features.

Let x be the **number**,

Where the Sum of a **number **and 4:

x + 4

Then Ten times the sum of a **number **and 4:

In the equation 0.44 x 0.72 = n, what is the value of n?

### Answers

**Answer:n=0.3168**

**Step-by-step explanation:**

**Answer:**

n = .3168

**Step-by-step explanation:**

Multiply .44 by .72.

You can use a calculator to do this or do it by hand.

If you choose to do it by hand, multiply using long multiplication without paying mind to the decimals, and then when you are finished, add the decimal four places to the left (at the very beginning of the number you should get). So, 3168 becomes .3168, or your final answer.

Sorry, I cannot really show all the steps of the multiplication itself on a computer but I hoped this helps :)

A rectangular table top has an area of 8ft and a perimeter of 12ft.What are the dimensions of the table?

### Answers

Answer:

Dimensions are 2 and 4

Step-by-step explanation:

Area= a*b=8

Perimeter=2(a+b)=12 => a+b = 12/2. a+b = 6

a+b=6 =>a=6-b

If a=2=>b=4 so 4+2=6 , 4*2=8 and 4*2+2*2=12

If a=4=>b=2 so 4+2=6 , 4*2=8 and 4*2+2*2=12

Dimensions are 2 and 4

The possible **dimensions** of the table are -

L = 2, B = 4.

or

L = 4, B = 2.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a **finite combination **of symbols that is well-formed according to rules that depend on the context.**Mathematical symbols** can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of** logical syntax**.

Given is a rectangular table top has an area of **8 ft** and a perimeter of **12 ft**.

Let the **dimensions** of the rectangular table be **{x} ft** and **{y} ft **respectively.

We can write -

**xy = 8 ....... Eq(1)**

2(x + y) = 12

**x + y = 6 ....... Eq(2)**

y = (6 - x)

Then, we can write -

x(6 - x) = 8

- x² + 6x = 8

x² - 6x + 8 = 0

(x - 2)(x - 4) = 0

We get -

x = 2 and x = 4

Now,

For x = 2, y = 4.

For x = 4, y = 2.

Therefore, the possible **dimensions** of the table are -

L = 2, B = 4.

or

L = 4, B = 2.

### Answers

**Answer:**

C: 19

**Step-by-step explanation:**

To start we would resolve the absolute value of [tex]|-3|[/tex]. We know that absolute value is the distance from zero so it would be 3.

Our new equation is [tex]3+6/(4-1)*8[/tex]

Now we need to solve in the order of PEDMAS starting with parenthesis to get [tex]3+6/3*8[/tex]

Next in PEDMAS we have Division/Multiplication since we don't have any exponents. We do all the division and multiplication left to right so we would divide to get [tex]3+2*8[/tex] and then multiply to get [tex]3+16[/tex].

Finally, we only have addition left over so our answer would be [tex]19[/tex]

A statistician believes that women received more bachelor's degrees than men did last year. To test this claim, she selects colleges and universities randomly and compares the number of bachelor's degrees awarded to men and women. Suppose that data were collected for a random sample of 7 colleges and universities, where each difference is calculated by subtracting the number of degrees earned by men from the number of degrees earned by women. Assume that the number of degrees is normally distributed. The statistician uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈2.968, which has 6 degrees of freedom, determine the range that contains the p-value.

### Answers

**Answer:**

0.0125

**Step-by-step explanation:**

The P-value can be calculated by using excel function T.DIST.RT(2.968,6).

Right tail is used in the function because our alternative hypothesis has greater than sign (>) whereas 2.968 represent test statistic value and 6 represents degree of freedom. The resultant p-value from excel function is 0.0125.

Or if we use t- distribution right tail area table, we see that 6 for degree of freedom the value in table is there are two value 2.44691 and 3.14627 which corresponds to p=0.025 and p=0.01. As 2.44691 is smaller than 2.968 so we take p=0.01 against 3.14627. Thus, in this scenario p-value would be 0.01.

What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?

A) x – 6

B) x – 3

C) x + 1

D) x + 6

### Answers

Answer:

D. x + 6

Step-by-step explanation:

In the given graph, we have 3 x-intercepts values, which are points at which the line intercepts the x-axis. They are, -6, -3 and 0.

Each of these x-intercepts can be written as a factor of a polynomial function as follows:

x = -6

x = -6 + 6

x + 6 = 0

x = -3

x = -3 + 3

x + 3 = 0

x = 0

Therefore, the factor of the polynomial function must be: x + 6
