Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x×10y years, where x and y are single-digit numbers.

Answers

Answer:

The age of pluto is:

5,560,000,000 years old = 5.56 × 10⁹ years old

x = 5.56

y = power of 9

Step-by-step explanation:

Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x×10y years, where x and y are single-digit numbers.

We write this in standard form or scientific notation.

5,560,000,000 years old = 5.56 × 10⁹ years old

x = 5.56

A professor is interested in comparing the characteristics of students who do and do not vote in elections. For a random sample of 114 students who claimed to have voted in the last presidential election, she found a mean CPA of 2.71 and a standard deviation of 0.64. For an independent sample of 123 students who did not vote, the mean CPA was 2.79 and the standard deviation was 0.56. Test at the 5% level of significance if the mean CPA of all students who vote is lower than the CPA of students who do not vote.

Answers

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is  

There is no sufficient evidence to conclude that the mean CPA of all students who vote is lower than the CPA of students who do not vote

Step-by-step explanation:

From the question we are told that

       The first sample size  is  [tex]n_1 =  114[/tex]

       The sample mean is  [tex]\= x_1 =  2.71[/tex]

       The standard deviation is  [tex]s_1 =  0.64[/tex]

      The second sample size is   [tex]n_2 =  123 [/tex]

      The sample mean is   [tex]\= x_2 =  2.79[/tex]

      The level of significance is  [tex]\alpha  =  0.05[/tex]

      The standard deviation is   [tex]s_2 =  0.56 [/tex]

The null hypothesis is  [tex]H_o  :  \mu_1 = \mu _2[/tex]

The alternative hypothesis is  [tex]H_a :  \mu_1 <  \mu_2[/tex]

Generally the test hypothesis is mathematically represented as

      [tex]t =  \frac{\= x_1 - \= x_2}{ \sqrt{ \frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2}  } }[/tex]

=> [tex]t =  \frac{2.71 - 2.79}{ \sqrt{ \frac{0.64^2 }{ 114} + \frac{0.56^2}{123}  } }[/tex]

=> [tex]t =  -1.01 [/tex]

Generally given that variance are not equal (the standard deviation  squared of both population are not equal ) the degree of freedom  is mathematically represented as

[tex]df  =  \frac{[\frac{s_1^2}{n_1 } + \frac{s_2^2}{n_2}  ]}{\frac{[\frac{s_1^2}{n_1}]^2 }{n_1 - 1} + \frac{[\frac{s_2^2}{n_2}]^2 }{n_2 - 1}}[/tex]

=>  [tex]df  =  \frac{[\frac{0.64^2}{114} + \frac{0.56^2}{123}  ]}{\frac{[\frac{0.64^2}{114}]^2 }{114 - 1} + \frac{[\frac{0.56^2}{123}]^2 }{123 - 1}}[/tex]

=>  [tex]df  =  225[/tex]

Generally from the t distribution table the the probability of  (t < -1.01) at a degree of freedom of [tex]df  =  225[/tex]is  

      [tex] p-value  = P(t <  -1.01 ) =  0.15679[/tex]

Generally the value obtained we see that  [tex]p-value  > \alpha[/tex] so

The decision rule is

Fail to reject the null hypothesis

The conclusion is  

There is no sufficient evidence to conclude that the mean CPA of all students who vote is lower than the CPA of students who do not vote

Step-by-step explanation:

Write a linear function f with f(-3)=1 and f(13)=5

Answers

Answer:

[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]

Step-by-step explanation:

Given

[tex]f(-3) = 1[/tex]

[tex]f(13) = 5[/tex]

Required

Determine the linear function

A function is of the form:

[tex]y = f(x)[/tex]

Writing the given parameters in (x,y) format, we have:

[tex]f(-3) = 1[/tex] implies (-3,1)

[tex]f(13) = 5[/tex] implies (13,5)

So, the x and y values are:

(-3,1) and (13,5)

i.e.

[tex](x_1,y_1) = (-3,1)[/tex]

[tex](x_2,y_2) = (13,5)[/tex]

First, we need to determine the slope using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{5 - 1}{13 - -(3)}[/tex]

[tex]m = \frac{4}{13 +3}[/tex]

[tex]m = \frac{4}{16}[/tex]

[tex]m = \frac{1}{4}[/tex]

The equation is calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex](x_1,y_1) = (-3,1)[/tex]

[tex]m = \frac{1}{4}[/tex]

[tex]y - 1 = \frac{1}{4}(x - (-3))[/tex]

[tex]y - 1 = \frac{1}{4}(x +3)[/tex]

[tex]y = \frac{1}{4}(x +3) + 1[/tex]

[tex]y = \frac{1}{4}x +\frac{3}{4} + 1[/tex]

[tex]y = \frac{1}{4}x +\frac{3+4}{4}[/tex]

[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]

Yes, because 2a · 38b = 4a · 19b where 4a and 19b are integers because a and b are integers and products of integers are integers. Yes, because 4a is a divisor of 38b. No, because 38 is not a divisor of 4. No, because 2a · 38b = 4a · 19b where 4a and 19b are not necessarily integers because products of integers are not always integers.

Question 1 of 3 NE A scale drawing of a fishing boat has a scale of 1 cmn to 2 meters. If the length of the fishing boat is 6 cm on the scale drawing, what is the actual length of the fishing boat?​

Answers

Answer:

Determine the measurement when the scale reads 6cm

Represent this scale with x;

Such that:

[tex]Scale = 6cm:x[/tex]

10. 639

11. 128

12. 399

13. Discount price= 12.87 Sale price= 26.13

14. 40.80

15. 12,750

I'm not 100% on #15 but the rest are good.

Step-by-step explanation: When you multiply the percent by the other number that gives you the difference. So then get the original number and either add or subtract the difference from the original number to get your answer. Add if increase Subtract if decrease.

So 7-11 you just have to multiply the percent by the other number.

7. 25*300% or 25*3 = 75  25 + 75 = 100

8. 56*.75 = 42  56-42= 14

9. 12000*.05 = 600 (since it is an increase add 600 to 12000) = 12600

10. 710*.10= 71 (71 is the difference so do this) 710-71= 639

11. 160*.20 = 32 (decrease) 160-32= 128

12. 380*.05=19 (increase) 380+19 = 399

13. 39*.33= 12.87 (decrease)

Discount price = 12.87

Sale price= 39-12.87= 26.13

14. 48*.15 = 7.20 (decrease) 48-7.20= 40.80

15. 3,000*3.25 = 9750 (increase) 9750 + 3000= 12,750

If f is decreasing on [a,b] then the minimum value of f(x) on [a,b] is f(a)?

Answer:

False

Step-by-step explanation:

Given

[a,b]

Where f(x) is decreasing

Required

Is the minimum f(a)?

This statement is false and it is proved using the following illustration

Take f(x) to be

[tex]f(x) = -2x[/tex]

The above represents a decreasing function because:

f(x) decreases as x increases

Having said that:

Assume [a,b] is:

[tex][a,b] = [2,5][/tex]

Substitute the value of a i.e. 2 for x in f(x)

[tex]f(2) = -2 * 2[/tex]

[tex]f(2) = -4[/tex]

Substitute the value of b i.e. 5 for x in f(x)

[tex]f(5) = -2 * 5[/tex]

[tex]f(5) = -10[/tex]

Notice that f(b) < f(a) i.e. -10 is less than -4

Hence:

f(x) is minimum at f(b)

Conclusively, the statement is false
