Step-by-step explanation:

Answer:

True

Step-by-step explanation:

For a compound inequality using the word "or" to be true, all you need is for one of the parts to be true.

-6 < 7 is true

-2 <= -2 is also true

Answer: True

Answer: 4

Step-by-step explanation:

Answer:

P(x)= -0.6x^3 + 500x^2  

Step-by-step explanation:

given data

monthly cost

C(x) = 400x^2 + 300x

revenue is

R(x) = -0.6x^3 + 900x^2 – 400x + 700,

where x is in thousands of boxes sold.

we know that the profit is the difference between the revenue and the cost.

therefore P(x)=R(x)-C(x)

P(x)= -0.6x^3 + 900x^2 – 400x + 700-(400x^2 + 300x )

P(x)= -0.6x^3 + 900x^2 – 400x + 700-400x^2 - 300x

P(x)= -0.6x^3 + 500x^2

Step-by-step explanation: the graph shows a line that is increasing.

Answer:

The rate is $2.5

Step-by-step explanation:

Given that the expression for the pay of employee is given as

P(b) = 5/2b + 45

we can simplify the fraction and write it as decimal as

P(b) = 2.5b + 45

This means that the employees have a fixed pay of $45

and also a rate of $2.5 per peaches picked

therefore the answer is A. $2.5

The rate is $2.5

Answer:SSS

Step-by-step explanation:

Answer:

There's your answer!

Step-by-step explanation:

To do these just grab a calculator, or if you know your multiplication tables like I do, it's extremely easy, for example, when multiplying 60 and 80, you can do it in your head by just multiplying 6 and 8 to get 48, then add the two zeros on the end from 60 and 80, and you'll get 4800.

Answer:

It looks as though it would be A because it starts at 30 and goes up steadily by 5. B increases too quickly, C does not increase, and D decreases.

Answer:

[tex]\angle ABD =42.4^{\circ}[/tex]

Step-by-step explanation:

We are given that Point C is in the interior of ∠ABD

We are also given that ∠ABC ≅ ∠CBD

Now ,

[tex]\angle ABC = (\frac{5}{8}x + 18)\\\angle CBD = (4x)[/tex]

Since we are given that ∠ABC ≅ ∠CBD

So, [tex]\frac{5}{8}x + 18=4x\\4x-\frac{5}{8}x=18\\\frac{32x-5x}{8}=18\\\frac{27x}{8}=18\\x=\frac{18 \times 8}{27}\\x=5.3[/tex]

[tex]\angle CBD = (4x)=4(5.3)=21.2^{\circ}[/tex]

[tex]\angle ABD = \angle CBD+\angle ABC=21.2+21.2=42.4^{\circ}[/tex]

Hence [tex]\angle ABD =42.4^{\circ}[/tex]

Answer:

Randomized block design

Step-by-step explanation:

A randomized block design is essentially an experimental design where the units of the experiment are in groups which are called blocks. Now, treatments are usually randomly allocated to the units of experiment inside each block and when all the treatments appear a minimum of one time in each block, we can conclude that we have achieved a completely randomized block design.

Now, in the question we see that the experimental units which is the "30 horses at high risk for enteroliths" are divided into 3 groups. We can call these groups blocks. Now we see that further treatments such as alfalfa diet, grass hay diet and oat hay diet are assigned to different horses each within those groups/blocks.

Now, this description fits the definition of a randomized block design given above.

Thus, the study is a randomized block design

Appropriately 10 hot dogs

Step-by-step explanation:

Answer:

60 × 50 = 3000

7 × 50 = 350

60 × 4 = 240

7 × 4 = 28

3000 + 350 + 240 + 28 =3618

54 × 67 = 3618

Answer:

4,757 pounds

Step-by-step explanation:

One case book weighs 34 pounds

One case of magazines weigh 25 pounds

A book store wants to ship 73 cases of book 91 cases of magazines

Therefore the total weight of the shipment can be calculated as follows

= 34×73 + 25×91

= 2482 + 2275

= 4,757

Hence the total weight of the shipment is 4,757 pounds

Answer:

28.9

Step-by-step explanation:

tan (18) = 9.4/x times x

x times tan(18) = 9.4 / tan(18)

            tan(18)

        crosses out.

On a calculator do 9.4/

                             tan(18).

x = 28.9

Answer:

The 90% confidence interval is   [tex]15.66< \mu < 15.94 [/tex]

Step-by-step explanation:

From the question we are told that

  The population standard deviation is  [tex]\sigma = 2.2[/tex]

  The  sample mean is  [tex]\= x = 15.8 \ gallon[/tex]

   The sample size is  n  =  669

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

=>  [tex]E = 1.645  *  \frac{ 2.2}{\sqrt{669} }[/tex]

=>  [tex]E = 0.1399[/tex]

Generally 90% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>    [tex]15.8  - 0.1399 <\mu<  15.8  + 0.1399 [/tex]

=>    [tex]15.66< \mu < 15.94 [/tex]

Answer:

The median monthly sales goal is $30000

Step-by-step explanation:

Monthly Sales Goals (in thousands)

Stem Leaf

1 8 9

2 5 6 6 8

3 2 3 3 6 9

4 0

Data (Salary in thousands) : 18,19,25,26,26,28,32,33,33,36,39,40

n = 12(even)

[tex]Median = \frac{\frac{n}{2} \text{th term}+(\frac{n}{2}+1) \text{th term}}{2}[/tex]

[tex]Median = \frac{\frac{12}{2} \text{th term}+(\frac{12}{2}+1) \text{th term}}{2}\\Median = \frac{6 \text{th term}+7 \text{th term}}{2}\\Median = \frac{28+32}{2}\\Median = 30[/tex]

So, The median monthly sales goal is $30000

So, Option C is true

The answer is 24, hopes this helps!

Answer:

about 37.31 inches of space

Step-by-step explanation:

In this case, you would need to find the area of a cylinder with these dimensions.

Formula: 2πrh+2πr²

The r is the radius, and since the diameter in this situation would be 2.5, the radius would be 1.25.

2π(1.25)(3.5)+2π(1.25)²

2π4.375+2π1.5625

8.75π+3.125π

37.3064128

about 37.31 inches of space

Answer:

[tex]Area = 105[/tex]

Step-by-step explanation:

Given

[tex]W = (-5,4)[/tex] ---- [tex](x_1,y_1)[/tex]

[tex]X = (3,4)[/tex] ------ [tex](x_2,y_2)[/tex]

[tex]Y = (6,-6)[/tex] ----- [tex](x_3,y_3)[/tex]

[tex]Z = (-7,-6)[/tex] ---- [tex](x_4,y_4)[/tex]

Required

Determine the area;

Area is calculated as thus:

[tex]Area = \frac{1}{2}[(x_1.y_2 +x_2.y_3 + x_3.y_4 + x_4.y_1)-(x_2.y_1 +x_3.y_2 + x_4.y_3 + x_1.y_4)][/tex]

Substitute values

[tex]Area = \frac{1}{2}[(-5*4 +3*-6 + 6*-6 + -7*4)-(3*4 +6*4 + -7*-6 + -5*-6)][/tex]

[tex]Area = \frac{1}{2}[(-102)-(108)][/tex]

[tex]Area = \frac{1}{2}[-102-108][/tex]

[tex]Area = \frac{1}{2}[-210][/tex]

[tex]Area = -105[/tex]

[tex]Area = 105[/tex]

None of the options answer the question:
