Answer:

Given the statement:

9 less than the sum of x and 5

"Sum of x and 5" means $x+5$

" $\text{less than}$ " means subtract

then;

the statement 9 less than the sum of x and 5 becomes;

⇒ $(x+5) - 9$

⇒ $x+5-9 = x-4$

Therefore, the expression for the given statement is $(x+5) - 9$

Find the four arithmetic means between 100 and 135. Show work.

Masteriza [31]

Answer:

Please read the answers below.

Step-by-step explanation:

Let's calculate the four means between 100 and 135, this way:

1. Arithmetic mean:

(100 + 135)/2 = 117.5

2. Weighted mean:

We will assign equal weight to both numbers : 5

(100 * 5 + 135 * 5)/10 = (500 + 675)/10 = 1,175/10 = 117.5

3. Geometric mean:

√100 * 135 = √13,500 = 116.2 (Rounding to the next tenth)

4. Harmonic mean:

2/(1/100 + 1/135) = 2/(0.01 + 0.0074) = 114.9 (Rounding to the next tenth)

Engineers must design a process for producing ammonia in amounts large enough to ensure a reasonable profit. Which criterion wou

ki77a [65]

The process needs to meet the following criterion:The process must make large amounts of product at a low cost. That is option A.

<h3>What is ammonia?</h3>

Ammonia is defined as a gas compound that is made up of nitrogen and oxygen in the ratio of 1:3 respectively.

The industrial and modern method constructed by Engineers for ammonia production is called steam reforming.

The natural resources used for industrial production of ammonia can be gotten from natural gas such as methane.

To make profit, natural products are used which costs less to acquire but will lead to the production of large ammonia quantity.

Determine whether this situation represents independent or dependent events. "Three green jelly bean, five red jelly beans and t

igor_vitrenko [27]

Answer:

Independent Events

Step-by-step explanation:

Given

$Green = 3\\ Orange = 2\\ Red = 5$

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

<u>Before selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

<u>After selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

Cells B1, C1, and D1 contain the values Seat1Row1, Seat1Row2, and Seat1Row3. If cells B1, C1, and D1 were selected, and autofill

Reil [10]

Answer:

The autofilled values would be Seat1Row4, Seat1Row5, Seat1Row6

Step-by-step explanation:

Given

B1 = Seat1Row1

C1 = Seat1Row2

D1 = Seat1Row3

Required

Values of E1, F1, G1 if autofilled

Autofill in Microsoft Office Excel (Ms Excel).is used to automatically fill cells base on suggestion from previous cells.

The autofill feature of Ms Excel works data types such as numbers and alphanumeric among others.

But for autofill to work on alphanumeric in Ms Excel, only the numeric part will be altered.

In this case, the series of text in B1, C1 and D1 are Seat1Row1, Seat1Row2, Seat1Row3

"Seat1Row" will be regarded as string while 1,2,3 will be incremented and the resulting alphanumeric values will be saved in their respective cells.

Hence,

Cell E1 will be filled with Seat1Row4

F1 will be filled with Seat1Row5

G1 will be filled with Seat1Row6
