as its the highest degree

Answer:

4.27 x [tex]10^{5}[/tex]

Step-by-step explanation:

The whole digit cannot go past 10 or be less than 1:

1 - 10 is the numbers of its max.

427,000

We would move the decimal point between 4 and 2 making:

4.2700

(Originally the decimal point moved 5 places because 427,000 is a whole number, which means the decimal point would be considered at the end, as shown below)

427,000.

By moving 5 places to the left this will be part of your: scientific notation as

___ x [tex]10^{5}[/tex]

(Then plug in 4.27 in front of your notation)

4.27 x [tex]10^{5}[/tex]

That is your answer!

Answer:

It is because it comes from the word 'ratio'. A rational number is usually known as the ratio of two integers, that's how it got its name. :)

Step-by-step explanation:

Price of lunch of each, P = $ 18.45/3 = $ 6.15 .

Now, number of people that can eat the barbecue at a budget of $1850.00 is:

[tex]n=\dfrac{1850}{6.15}\\\\n=300.81[/tex]

Therefore, Mr. Gaines afford maximum 300 people to feed on a budget of $1850.00 .

Hence, this is the required solution.

The missing figures in the question can be seen below.

The average retirement age = 56.1 years ...

The number of a  survey of retired citizen = 49

The standard deviation of the retirement age is 6 years.

Using alpha ∝ = 0.02

Answer:

Step-by-step explanation:

From the given options in the first question in the given information.

Type I error can take place when the researcher concludes the average retirement age increased, but the average retirement age did not increase.

A Type II error can take place when the researcher concludes that the average retirement age did not increase, but the average retirement age increased.

Recall that:

population mean = 56.1

sample size = 49

standard deviation = 6

At the level of significance of 0.02, using the Excel function (=Normsinv(0.02))

The critical value for z = 2.054

Standard error = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]

=[tex]\dfrac{6}{\sqrt{49}}[/tex]

= 6/7

= 0.857

The rejection region [tex]\overline X[/tex] = [tex]\mu +Z_{\alpha/0.02}*\sigma_x[/tex]

[tex]\overline X[/tex] = [tex]56.1+2.05374891*0.857[/tex]

[tex]\overline X[/tex] = 57.86

P(Type II error) is as follows:

[tex]P(\overline X < 57.86| \mu = 57.4) = P( Z< \dfrac{\overline X - \mu }{\sigma_x})[/tex]

[tex]= P( Z< \dfrac{57.86-57.4}{0.857})[/tex]

[tex]= P( Z< 0.537)[/tex]

From z tables;

P (Type II error) = 0.704

P(Type II error) is as follows:

[tex]P(\overline X < 57.86| \mu = 58.9) = P( Z< \dfrac{\overline X - \mu }{\sigma_x})[/tex]

[tex]= P( Z< \dfrac{57.86-58.9}{0.857})[/tex]

[tex]= P( Z<-1.214)[/tex]

From z tables;

P (Type II error) = 0.1124

Answer:

The equation y = -3r + 13 does not belong with the other three.

Step-by-step explanation:

We have 4 equations

The first 3 equations have relations between two variables x and y

So they are linear equations of two variables x and y

The fourth equation has a relation between two variables r and y

So it is a linear equation of two variables r and y

The fourth equation does not belong to with the first three equations because it has a different variable r

The equation y = -3r + 13 does not belong with the other three.

Step-by-step explanation:

Answer:

yup it and is correct and is 15

Answer:

38.28cm²

Step-by-step explanation:

The area of the figure can be determined by expression the figure as two shapes.

  A semicircle and trapezium;

 Area of shape  = Area of semicircle + Area of trapezium

Now;

 Area of semicircle  = [tex]\frac{\pi r^{2} }{2}[/tex]

  Where r is the radius, which is [tex]\frac{4}{2}[/tex] = 2cm;

   Area of semicircle  = [tex]\frac{3.142 x 2^{2} }{2}[/tex]   = 6.28cm²

Area of trapezium;

        = [tex]\frac{1}{2} (a + b)h[/tex]

a and b are the base length = 6cm and 10cm

 h is the height = 4cm

Input the parameters and solve;

       =  [tex]\frac{1}{2} (6 + 10) 4[/tex]  

       = 32cm²

The area of the shape = 6.28cm² + 32cm² = 38.28cm²

Hope this helps

Answer:

Step-by-step explanation:

From the given question:

The slope is expressed as;

[tex]\thteta (x) = \dfrac{dy}{dx} - - (1)[/tex]

[tex]\thteta (x) = \dfrac{dy}{dx}\left \{ {{\dfrac{y(x+b)-y(x)}{h} \ \ \to approximate} \atop {\dfrac{1}{100}}(-4+4x-3x^2+2x^3) \ \to \ exact } \right.[/tex]

∴

[tex]\theta (x) _{approximate} = \dfrac{y(1+0.3)-y(1)}{0.3}[/tex]

[tex]\theta (x) _{approximate} = \dfrac{y(1.3)-y(1)}{0.3}[/tex]

[tex]\theta (x) _{approximate} = -2.965 \times 10^{-5}[/tex]

[tex]\theta(x)_{exact} = \dfrac{1}{100}(-4+4-3+2)[/tex]

[tex]\theta(x)_{exact} = -0.01[/tex]

Finally, the true percent relative error TPRE is:

[tex]TPRE= \dfrac{ | \theta(x)_{approximate} -\theta (x)_{exact} }{\theta (x)_{exact} }\times 100\%[/tex]

[tex]TPRE= \dfrac{ 2.965 \times 10^5 --0.01}{-0.01}\times 100\%[/tex]

TPRE = 70..35%

Answer:

x = -1

Step-by-step explanation:

first, create a formula or expression:

7x - 2 = 10x + 1

now, move the 10x, subtract it on the other side

-3x - 2 = 1

add 2

-3x = 3

divide by -3

x = -1

you can substitute it in to check

Answer:

Step-by-step explanation:

x + y = 180

3x = y

x + 3x = 180

4x = 180

x = 45

3*45 = y

y = 135

The two angles are

Answer: c

Step-by-step explanation: we know that odd numbers can’t be divided by 2 so take a out, then we see that 90 is the only one because 90/2=30, 90/9=10, and 90/10=9

Answer:

Yes, the answer is C. 90..

Answer:

3.6 hours

Step-by-step explanation:

To solve, create a Rate, Time, Work chart:

Work is rate times time. For Kevin, his work is going to equal x over 6 job. For Anna, her expression for work will equal x over 9 job.

The work is 1 job of calling all clients, so their combined work is equal to 1.  

x over 6 plus x over 9 equals 1

In the rational equation, x is the amount of time it takes Kevin and Anna to call the clients together.  With rational equations, the terms can be added together once they have common denominators.  

x over 6 plus x over 9 equals 1

fraction numerator begin display style x left parenthesis 9 right parenthesis end style over denominator begin display style 6 left parenthesis 9 right parenthesis end style end fraction plus fraction numerator begin display style x left parenthesis 6 right parenthesis end style over denominator begin display style 9 left parenthesis 6 right parenthesis end style end fraction equals fraction numerator begin display style 1 left parenthesis 6 right parenthesis left parenthesis 9 right parenthesis end style over denominator left parenthesis 6 right parenthesis left parenthesis 9 right parenthesis end fraction

fraction numerator 9 x over denominator 54 end fraction plus fraction numerator 6 x over denominator 54 end fraction equals 54 over 54

9 x plus 6 x equals 54

15 x equals 54

x equals 3.6

If Kevin and Anna work together, they can call all the clients in 3.6 hours.

Answer:

Reject H₀. There is a significant difference in drug resistance between the two states.

Step-by-step explanation:

In this case we need to determine whether the data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states.

The significance level of the test is, α = 0.02.

(1)

The hypothesis can be defined as follows:  

H₀: There is no difference between the proportions of drug-resistant cases in the two states, i.e. [tex]p_{1} - p_{2}= 0[/tex].  

Hₐ: There is a statistically significant difference between the proportions of drug-resistant cases in the two states, i.e. [tex]p_{1} - p_{2}\neq 0[/tex].  

(2)

Compute the sample proportions and total proportion as follows:

[tex]\hat p_{1}=\frac{12}{189}=0.063\\\\\hat p_{2}=\frac{8}{429}=0.019\\\\\hat p=\frac{12+8}{189+429}=0.032\\[/tex]

Compute the test statistic value as follows:

[tex]Z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{\hat p(1-\hat p)\times [\frac{1}{n_{1}}+\frac{1}{n_{2}}]}}[/tex]

   [tex]=\frac{0.063-0.019}{\sqrt{0.032(1-0.032)\times [\frac{1}{189}+\frac{1}{429}]}}\\\\=2.86[/tex]

The test statistic value is 2.86.

(3)

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

Compute the p-value as follows:

[tex]p-value=2\cdot P(Z>2.86)=2\times 0.00212=0.00424[/tex]

p-value = 0.00424 < α = 0.02.

The null hypothesis will be rejected at 0.02 significance level.

Reject H₀. There is a significant difference in drug resistance between the two states.
