-x²+10x-21 = 0

x = (-10±√(10²-4×(-1)×(-21)))/2×(-1)

x = (-10±√(100-84))/-2

Isaac's finish 7 heavy cleans every 5 minutes Ryan finish heavy 8 clean every 4 minutes how many more cleans did Isaac complete than

You need to make each person have done work the same amount of time that is a multiple of 4 and 5. The closest is 20. So multiply 5 to 8 cleans for Ryan and 4 to 7 cleans for Issac. 40 cleans for Ryan - 28 cleans for Issac = **12 more cleans for RYAN, not Issac.**

A toy manufacturer wants to know how many new toys children buy each year. A sample of 305 children was taken to study their purchasing habits. Construct the 80% confidence interval for the mean number of toys purchased each year if the sample mean was found to be 7.6. Assume that the population standard deviation is 1.5. Round your answers to one decimal place.

**Answer:**

The 80% confidence interval for the mean number of toys purchased each year is between 7.5 and 7.7 toys.

**Step-by-step explanation:**

We have that to **find **our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.8}{2} = 0.1[/tex]

**Now**, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.1 = 0.9[/tex], so Z = 1.28.

**Now, find the margin of error M as such**

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.28\frac{1.5}{\sqrt{305}} = 0.1[/tex]

The **lower end** of the interval is the sample mean subtracted by M. So it is 7.6 - 0.1 = 7.5

The **upper end** of the interval is the sample mean added to M. So it is 7.6 + 0.1 = 7.7

The 80% confidence interval for the mean number of toys purchased each year is between 7.5 and 7.7 toys.

In 2012, the world population was 7.02 billion. The birth rate had stabilized to 134 million per year and is projected to remain constant. The death rate is projected to increase from 56 million per year in 2012 to 80 million per year in 2040 and to continue increasing at the same rate.

(a) Assuming the death rate increases linearly, write a differential equation for P(t), the world population in billions t years from 2012.

(b) Solve the differential equation.

(c) Find the population predicted for 2050.

**Answer:**

[tex](a)\ \frac{dP}{dt} = 0.078- 0.000857t[/tex]

[tex](b)\ P = 0.078t- 0.0004285t^2 + 7.02[/tex]

[tex](c)\ 9.37\ billion[/tex]** **

**Step-by-step explanation:**

**Given**

**In 2012**

[tex]P(t) = 7.02\ billion[/tex]

[tex]R_1 = 134\ million/year[/tex]** --- Birth rate**

[tex]R_2 = 56\ to\ 80[/tex] -- Death rate from '12 to '40

**Solving (a): Equation for population from 2012**

**In 2012, we have the addition in population to be:**

[tex]\triangle P= Birth - Death[/tex]

[tex]\triangle P= 134 - 56[/tex]

[tex]\triangle P = 78[/tex]** million**

**From 2012 to 2040, we have the death rate per year to be:**

[tex]Rate/yr = \frac{80 - 56}{2040 - 2012}[/tex]

[tex]Rate/yr = \frac{24}{28}[/tex]

[tex]Rate/yr = \frac{6}{7}[/tex] million/year

**So, the differential equation is:**

[tex]\frac{dP}{dt} = \triangle P - Rate/yr * t[/tex]** where t represents time**

[tex]\frac{dP}{dt} = 78 - \frac{6}{7} * t[/tex]

[tex]\frac{dP}{dt} = 78 - \frac{6t}{7}[/tex]

**Express in millions**

[tex]\frac{dP}{dt} = \frac{78}{1000} - \frac{6t}{7000}[/tex]

[tex]\frac{dP}{dt} = 0.078- 0.000857t[/tex]

**Solving (b): The solution to the equation in (a)**

[tex]\frac{dP}{dt} = 0.078- 0.000857t[/tex]

**Make dP the subject**

[tex]dP = (0.078- 0.000857t)dt[/tex]

**Integrate both sides**

[tex]\int dP = \int (0.078- 0.000857t)dt[/tex]

[tex]P = \int (0.078- 0.000857t)dt[/tex]

**This gives:**

[tex]P = 0.078t- \frac{0.000857t^2}{2} + c[/tex]

[tex]P = 0.078t- 0.0004285t^2 + c[/tex]

**Solve for c.**

**When t = 0; P = 7.02**

**So, we have:**

[tex]7.02 = 0.078*0- 0.0004285*0^2 + c[/tex]

[tex]7.02 =0-0 + c[/tex]

[tex]7.02 =c[/tex]

[tex]c = 7.02[/tex]

**So:**

[tex]P = 0.078t- 0.0004285t^2 + c[/tex]

[tex]P = 0.078t- 0.0004285t^2 + 7.02[/tex]

**Solving (c): The population in 2050**

**We have:**

[tex]P = 0.078t- 0.0004285t^2 + 7.02[/tex]

**In 2050, the value of t is:**

[tex]t = 2050 - 2012[/tex]

[tex]t = 38[/tex]

**So, the expression becomes**

[tex]P = 0.078*38- 0.0004285*38^2 + 7.02[/tex]

[tex]P \approx 9.37\ billion[/tex]

Please give me the correct answer.Only answer if you're very good at math.Please use the Pythagorean Theorem formula which is a^2 + b^2 = c^2.

**Answer:**

c = 8.7 inches

**Step-by-step explanation:**

a^2 + b^2 = c^2

Substitute in the known values for a and b (the order doesn't matter):

(4.8)^2 + (7.3)^2 = c^2

multiply 4.8 times itself, 7.3 times itself:

23.04 + 53.29 = c^2

76.33 = c^2

Now find the square root of both sides of the equation (square root of c^2 = c):

8.736= c

It says round to the nearest tenth, so c = 8.7 inches
