Why is it important to know how to change dissimilar fractions to similar fractions especially in adding and subtracting fractions ?

Answers

Answer:

Fast, since we can't explicitly add or subtract them. This will lead us to an incorrect response.  

Step-by-step explanation:

In this question we assume a value and solve its value which can be defined as follows:

Let the value:

[tex]\to \frac{3}{2}+\frac{4}{5}\\\\[/tex]

solve the above value by taking LCM that is equal to 10

Albuterol is used to calm bronchospasm. It has a biological half-life of 7 hours and is normally inhaled as a 1.25 mg dose. (Note: Use the concepts of half-life or doubling time. The biological half-life of a substance is the amount of time it takes for the physiologic or radiologic activity of that substance to reduce by half.)

Required:
a. Find a model for the amount of albuterol left in the body t hours after an initial dose of 1.25 mg.
b. How much albuterol is left in the body after 24 hours?

Answers

Answer:

a. N(t) = 1.25 (1/2)^t/7

b. 0.1160933038mg.

Step-by-step explanation:

The formula for half life =

N(t) = No(1/2)^t/t½

Where N(t) = Amount of Substance left

No = Initial amount not Substance

t = time after t years

t½ = Half life of the substance

From the question:

No = 1.25mg

t½ = 7 years

a. Find a model for the amount of albuterol left in the body t hours after an initial dose of 1.25 mg.

N(t) = No(1/2)^t/t½

No = 1.25mg

t½ = 7 years

N(t) = 1.25 (1/2)^t/7

b. How much albuterol is left in the body after 24 hours?

Using the model in the above question

N(t) = 1.25 (1/2)^t/7

N(t) = 1.25(1/2)^24/7

N(t) = 1.25(0.5)^3.4285714286

N(t) = 0.1160933038mg

Therefore, the quantity of albuterol left in the body after 24 hours is 0.1160933038mg.

In a certain​ chemical, the ratio of zinc to copper is 3 to 17. A jar of the chemical contains 799 grams of copper. How many grams of zinc does it​ contain?

Answers

Answer:

let's see what to do buddy...

Step-by-step explanation:

[tex] \frac{zinc}{copper} = \frac{3}{17} \\ \\ \frac{zinc}{799} = \frac{3}{17} [/tex]

Multiply the sides of the equation by 799

[tex]zinc = \frac{3}{17} \times 799 \\ \\ zinc = \frac{3}{17} \times 17 \times 47 \\ \\ zinc = 3 \times 47 = 141 [/tex]

So A jar of the chemical contains 141 grams of zinc.

And we're done.

Thanks for watching buddy good luck.

Jon has 60,500 cars. He is a car dealer. 60% of the cars are green. How many cars are green?

Answers

Answer:

36300

Step-by-step explanation:

Answer:

The answer is 36,300.

Step-by-step explanation:

Okay, here's what we know, Jon has 60,500 cars and 60% of those cars are green. And what we are trying to figure out is how many cars are green.

So we need to convert the problem to an equation using the percentage formula: P% * C = G.

P stands for the percentage, C stands for the total number of cars, and G stands for the total number of green cars.

1. The percentage of green cars is 60% of all the cars. The variable C is 60,500, so the equation is 60% * 60,500 = G.

2. Convert 60% to a decimal by removing the percent sign and dividing by 100: 60/100 = 0.6.

3. Substitute 0.6 for 0.6% in the equation: 60% * 60,500 = G.

4. G becomes 0.6.

5. Do the math: 0.6 * 60,500 = 36,300.

6. G = 36,300.

So 60% of 60,500 is 36,300 and 36,300 cars are green

Let's double check our answer with the original question: What is 60% of 60,500?

Multiply 0.6 * 60,500 = 36,300

So yes, our answer is correct and Jon has 36,300 green cars.

What is the equation of a line passing through two points?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

Taking only two points from the table will be (4, 6) and (12, 8). Then the equation of the line is given as,

(y - 6) = [(8 - 6) / (12 - 4)](x - 4)

y - 6 = 1/4(x - 4)

y - 6 = (1/4) x - 1

y = (1/4)x + 5

The y-intercept and slope of the line described by these points will be y = (1/4)x + 5.

C) If we took many samples of size 50 from the population of all inductees and recorded the proportion who were performers for each sample, what shape do we expect the distribution of sample proportions to have where do we expect it to be centered?

Answers

Complete Question

The complete question is shown on the first uploaded image

Answer:

a

 center is  0.275

 [tex]SE = 0.063[/tex]

b

 center is  0.275

 [tex]SE = 0.020[/tex]

Step-by-step explanation:

considering question a

From the question we are told that

   The sample size is  n  =  50

 The proportion of  US adults are college graduates is  p = 0.275

Generally the center is equivalent to the proportion so the center is  0.275

Generally the standard error is  

      [tex]SE =  \sqrt{\frac{p *  (1- p)}{ n} }[/tex]

=>   [tex]SE =  \sqrt{\frac{0.275 *  (1- 0.275)}{ 50} }[/tex]

=>   [tex]SE = 0.063[/tex]

considering question b

    The sample size is  n  =  500

      The proportion of  US adults are college graduates is  p = 0.275

     Generally the center is equivalent to the proportion so the center is  0.275

     Generally the standard error is  

      [tex]SE =  \sqrt{\frac{p *  (1- p)}{ n} }[/tex]

=>   [tex]SE =  \sqrt{\frac{0.275 *  (1- 0.275)}{ 500} }[/tex]

=>   [tex]SE = 0.020[/tex]

In the sampling distribution, the center of the sampling distribution is 0.275 and the standard error is 0.063.

What is sampling distribution?

A sampling distribution simply means the probability distribution that is gotten from a larger number of samples that are drawn from a population.

In this case, the center of the sampling distribution is 0.275 and the standard error is 0.063. The standard error will be:

= [p × (1 - p)]/n

= [0.275 × (1 - 0.275)]/50

= 0.0039875

= ✓0.0039875

= 0.063

Also, when the sample is 500, the center of the sampling distribution is 0.275 and the standard error is 0.020.

An appliance manufacturer claims to have developed a new toaster oven that consumes an average of no more than 250 W. From previous studies, it is believed that power consumption for toaster ovens is normally distributed with a standard deviation of 18 W. A consumer group suspects the actual average is more than 250 W. They take a sample of 16 toaster ovens and calculate the average consumption to be 260 W. Answer the following questions:

a. Would you reject the Null at 1% level of significance?
b. Would you say the toaster oven consumes more than 250 W of power if you are willing to commit a Type 1 Error of 2.5%?
c. What is the cut-off Watts at 2.5% level of significance?
d. In reality, suppose the average power consumption is 265 W. What is the Type II error when Type I error is set at 2.5%?
e. What is the cut-off Watts at 1% level of significance?
f. In reality, suppose the average power consumption is 265 W. What is the Type II error when Type I error is set at 1%?
g. Based on these calculations, what happens to Type II error if Type I error is lowered?
h. Based on these calculations, what happens to Type I error if Type II error is increased?


Answers

Answer:

a. No the null hypothesis cannot be rejected at  1% level of significance as the calculated value of z= 2.222 which lies with in 2.333

b. Yes for the  Type 1 Error of 2.5% we say the toaster oven consumes more than 250 W of power because the calculated value 2.22 lies outside the region for 1.96

c. The cut-off at 2.5% level of significance is 258.82 W.

d. 0.85 is the area for Type 2 error.

(A)

N(T(t)) = 416t² - 242.4 - 135.16

(B)

Time = 27.30 hours

Step-by-step explanation:

Given

N(T) = 26T² - 123T + 25

T(t) = 4t + 1.2

Solving for the composite function.

Substitute T for 4t + 1.2 in N(T)

N(T(t)) = 26(4t + 1.2)² - 123(4t + 1.2) + 25

N(T(t)) = 26(4t+1.2)(4t + 1.2) - 123(4t + 1.2) + 25

N(T(t)) = 26(16t² + 9.6t + 1.44) - 492t - 147.6 + 25

N(T(t)) = 416t² + 249.6t + 37.44 - 492t - 172.6

N(T(t)) = 416t² + 249.6t - 492t + 37.44 - 172.6

N(T(t)) = 416t² - 242.4 - 135.16

Solving for time.

We have that

N(T) = 16044

N(T) = 26T² - 123T + 25

This gives

16044 = 26T² - 123T + 25

26T² - 123T + 25 - 16044 = 0

26T² - 123T - 16019 = 0

Solve by quadratic, we have.

T = 27.299506396472

Or

T = -22.568737165703

Since time can't be negative

T = 27.299506396472

T = 27.30 (approximately)

As, Total goals = 10 in two games

Let x be the number of goals that a soccer team scored in the first half

and, y be the number of goals that a soccer team scored in the second half

So, x+ y = 10

x= 2 and y = 8
