Answers

The complete expression will be written as 12+2x =  2( 6 + x).

What does a mathematical expression mean?

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.

                        This mathematical operation may be addition, subtraction, multiplication, or division.

Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,

   2( 6 + x)

  = 12 + 2x

12+2x =  2( 6 + x)

Therefore, the complete expression will be written as 12+2x =  2( 6 + x).

The formula for the volume, V, of a shape is given by V = Ah. A is the area and h is the height.
(a) Find the volume of the shape if A = 40 and h = 8
(b) Find the area of the shape if V= 800 and h = 20

Answers

Answer:

Step-by-step explanation:

a) V= A*h            V=40*8=320

b) V=800 and h=20

A=V/h=800/20=40

Answer:

see explanation

Step-by-step explanation:

Given the formula

V = Ah

with A = 40 and h = 8 , then

V = 40 × 8 = 320 units³

(b)

Given V = 800 and h = 20, then

800 = 20A ( divide both sides by 20 )

A = 40 units²

The weights of dogs at a kennel are Normally distributed with a mean of 18 pounds and a standard deviation of 3.5 pounds.In which percentile is a dog who weighs 25 pounds?

Answers

Answer:

P(x=25)=P(z=2)=0.9972 or 99.72%

Step-by-step explanation:

Mean = 18 pounds

Standard Deviation = 3.5 pounds

x= 25

We need to find P(x=25)

First, we need to find z-score using formula: [tex]z-score=\frac{x-\mu}{\sigma}[/tex]

Finding z-score when x=25

[tex]z-score=\frac{x-\mu}{\sigma}\\z-score=\frac{25-18}{3.5}\\z-score=2[/tex]

So, we need to find P(z=2)=P(x=25)

Looking at z-score table we can find P(z=2)

P(z=2)=0.9972 or 99.72%

So, P(z=2)=0.9972 or 99.72%

Answer:

97.5th percentile

Lucille has an aquarium with 9 gallons of water which weighs 85 pounds. The stand holding the aquarium can hold no more than 112 pounds. She wants to add 2.5-pound rocks, r, her tank. Complete the inequality to show how many rocks she can add. R≤

Answers

Answer:

[tex]r\leq 10.8[/tex]

OR

[tex]r\leq 10[/tex]

Step-by-step explanation:

Given that:

Amount of water in the aquarium = 9 gallons

Weight of water in the aquarium = 85 pounds

Total weight that aquarium can hold = 112 pounds

Weight of each rock = 2.5 pounds

To find:

The inequality to find the number of rocks, [tex]r[/tex] that can put in her tank.

Solution:

First of all, let us find more weight that the aquarium can hold after putting the water in the aquarium.

Additional weight that can be put in the aquarium = Total weight - Weight of water = 112 - 85 = 27 pounds

This 27 pounds can be of rocks.

Let the number of rocks that can be put in the aquarium = [tex]r[/tex]

Total weight of [tex]r[/tex] number of rocks = Weight of one rock multiplied by [tex]r[/tex]=2.5[tex]r[/tex]

Now, this weight of rocks must be lesser than or equal to 27 pounds.

Therefore, the in equality is:

[tex]2.5r\leq =27\\\Rightarrow r \leq 10.8\\OR\\\Rightarrow r \leq 10[/tex]

Here, we want to list the students in order from lowest to highest

The key here is to have the scores in the same form, let us say decimals for ease of comparison

Jenna: 85% = 85/100 = 0.85

Linda’s= 32/40 = 80% = 0.8

Karl = 7/8 = 0.875

My drawing! Do you guys like it?? A European apparel manufacturer has production facilities in Italy and China to serve its European market, where annual demand is for 1.9 million units. Demand is expected to stay at the same level over the foreseeable future. Each facility has a capacity of 1 million units per year. With the current exchange rates, the production and distribution cost from Italy is 10 euro per unit, whereas the production and distribution cost from China is 7 euro. Over each of the next three years, the Chinese currency could rise relative to the euro by 15 percent with a probability of 0.5 or drop by 5 percent with a probability of 0.5.
