D. The neighbors will remain suspicious of Goodman

Explanation:

He still can't explain anything + I took the test :)

by CODY

The neighbors will start to believe that Les Goodman is an alien.

Option (D) is correct.

It is to find will most likely happen next?

More Likely (More Probable) One event (A) is more likely to occur than another event (B) when the theoretical probability of the event (A) is greater then that of the other event (B).

This excerpt is from the play the Monsters Are Due on Maple Street.

In this play, the people become suspicious of less Godman as they observe some unusual activities in the town.

They start gossiping about the roar of sound and a flash of light that took place at midnight.

The people of the town got scared but they heard nothing when they turned their radios on.

so, the neighbors will start to believe that Les Goodman is an alien.

Answer:

a)

Null Hypothesis            H₀ : μ = 30

Alternative Hypothesis H₁ : μ < 30

b)

p-value = 0.0099

c)

Since 0.0099 < 0.05

Therefore, there is enough evidence to conclude that blood transfusion improved the cognitive functions of 2-year old mice.  

Step-by-step explanation:

Given the data in the question,  

a) State the hypotheses.

Null Hypothesis            H₀ : μ = 30

Alternative Hypothesis H₁ : μ < 30

b) What is the p-value

Test statistics

t = ([tex]x^{bar}[/tex] - μ) / s/√n

t = (29 - 30) / (2/√25)

t = -1 / 0.4

t = -2.5

degree of freedom df = n-1 = 25 - 1 = 24

from table

p-value = 0.0099

c) Using α = 0.05, what is your conclusion?

p-value = 0.0099

α = 0.05

0.0099 < 0.05

So, there is enough evidence to conclude that blood transfusion improved the cognitive functions of 2-year old mice.  

Answer:

174.23 lower p/month

Step-by-step explanation:

7 yr car loan = 38000 x 1.0432^7 =51092.4402043 =$51092.44 total pay back

51092.4402043/84=608.243335765 =$608.24

5 yr car loan = 38000 x 1.0432^5=46948.4748551 =$46948.48 total pay back

46948.4748551/60 =782.474580918 = 782.48 p/month

Amount difference

782.474580918-608.243335765 =174.231245153 =$174.23

For 7 year car loan, the monthly payment will be $180.96 lower as compare to 5 year car loan.

The simple interest is computed as,

                   [tex]A=\frac{P*R*T}{100}[/tex]

Where P is principle, R is rate and T is time.

Given that, cost of car [tex]P=38000,R=4.32,T=5years[/tex]

Substitute values in above equation.

           [tex]A=\frac{38000*4.32*5}{100} =8208[/tex]

The amount paid in 5 years[tex]=38000+8208=46208[/tex]

Amount paid per month is, [tex]=\frac{46208}{60}=770.14[/tex]

For 7 years,

           [tex]A=\frac{38000*4.32*7}{100}=11491.2[/tex]

Amount paid per month is,[tex]=\frac{49491.2}{84}=589.18[/tex]

The Amount difference is, [tex]=770.14-589.18=180.96[/tex]

For 7 year car loan, the monthly payment will be $180.96 lower as compare to 5 year car loan.

Answer:

23.2586 ; IQ ; hours spent studying per week

Step-by-step explanation:

Given the regression model:

y = 6.9+0.055x1 +0.107x2 + 0.0853X3.

IQ scores = (X1)

Hours spent studying each week = (X2),

one's high school average = (x3)

The multiple standard error is 6.313 and R^2=0.826.

What is the predicted GPA for a student with a IQ of 108, 32 hours spent studying per week and a high school average of 82?

X1 = 108 ; X2 = 32 ; X3 = 82

y = 6.9 + 0.055(108) + 0.107(32) + 0.0853(82)

y = 23.2586

B.

The Independent variable with the smallest effect on GPA is the variable with the smallest Coefficient, which is IQ with a Coefficient of 0.055

C.

The Independent variable whiae unit change has the greatest effect on GPA is X2, hours spent studying per week as it has the highest Coefficient of all independent variables with a Coefficient value of 0.107.

Given:

  triangular garden with base 7 ft and area 28 ft^2

Find:

  height of the triangle

Solution:

The formula for the area of a triangle is ...

  A = 1/2bh . . . . . where A is the area, b is the base length, and h is the height

Multiplying by 2/b, we can get a formula for the height. Using this formula, we can solve the problem.

  h = 2A/b

We can let h represent the height, and fill in the given data.

  h = 2(28 ft^2)/(7 ft)

  h = 8 ft

The height of the triangle is 8 feet.

Answer:

Part A

the dotted line formes the thrid side of the triangle.

part B

The length is the unknon side increases while kepping the known side lenths fixed, measuremnt of anggle Z will increas. So, the tringle will not fir the given conditions anymore.

part c

If the length of he unknown side decrases while keeping h known side lengths fixed,the measure of angle will decrease so he tringle will not fit the given conditions anymore.

part D

You know the given conditions for the triangle are fixed you also know the unknown side length is fixed. What dose the this tell you angles adjacent to the unknown side.

part e

The given condiction are fixed and the unknown side lenghtis fixed, the angles adjacent to the unknown side must much also be fixed.

part f

Given two side lengths and the measurement of the angle between them, only one triangle can be constructed. Part G The length of the unknown side (c) is 9.76 centimeters

Answer:

The tool gave a message that read, “The specified values do not match a valid triangle.” That is because the sum of the lengths of two sides of a triangle must be greater than the length of the third side. In this case, the sum is equal to the third side, not greater than the third side:

7 + 6 = 13. No triangles can be constructed with the given conditions.

Answer:

Step-by-step explanation:

-32 = 2(x² + 10x)

Complete the square

 coefficient of the x term: 10

 divide coefficient in half: 5

 square it: 5²

 use 5² to complete the square and keep the equation balanced:

-32+2·5² = 2(x² + 10x + 5²)

18 =2(x+5)²

9 = (x+5)²

x+5 = ±√9 = ±3

x = ±3 - 5 = -2, -8

Answer:

Step-by-step explanation:

From the information given:

the rate of the cars = [tex]\dfrac{1}{5} \ car / min = 0.2 \ car /min[/tex]

the rate of the buses = [tex]\dfrac{1}{10} \ bus / min = 0.1 \ bus /min[/tex]

the rate of motorcycle = [tex]\dfrac{1}{30} \ motorcycle / min = 0.0333 \ motorcycle /min[/tex]

The probability of any event at a given time t can be expressed as:

[tex]P(event \ (x) \ in \ time \ (t)\ min) = \dfrac{e^{-rate \times t}\times (rate \times t)^x}{x!}[/tex]

∴

(a)

[tex]P(2 \ car \ in \ 20 \ min) = \dfrac{e^{-0.20\times 20}\times (0.2 \times 20)^2}{2!}[/tex]

[tex]P(2 \ car \ in \ 20 \ min) =0.1465[/tex]

[tex]P ( 1 \ motorcycle \ in \ 20 \ min) = \dfrac{e^{-0.0333\times 20}\times (0.0333 \times 20)^1}{1!}[/tex]

[tex]P ( 1 \ motorcycle \ in \ 20 \ min) = 0.3422[/tex]

[tex]P ( 0 \ buses \ in \ 20 \ min) = \dfrac{e^{-0.1\times 20}\times (0.1 \times 20)^0}{0!}[/tex]

[tex]P ( 0 \ buses \ in \ 20 \ min) = 0.1353[/tex]

Thus;

P(exactly 2 cars, 1 motorcycle in 20 minutes) = 0.1465 × 0.3422 × 0.1353

P(exactly 2 cars, 1 motorcycle in 20 minutes) = 0.0068

(b)

the rate of the total vehicles = 0.2 + 0.1 + 0.0333 = 0.3333

the rate of vehicles with exact change = rate of total vehicles × P(exact change)

[tex]= 0.3333 \times \dfrac{1}{4}[/tex]

= 0.0833

∴

[tex]P(zero \ exact \ change \ in \ 10 minutes) = \dfrac{e^{-0.0833\times 10}\times (0.0833 \times 10)^0}{0!}[/tex]

P(zero  exact  change  in  10 minutes) = 0.4347

c)

The probability of the 7th motorcycle after the arrival of the third motorcycle is:

[tex]P( 4 \ motorcyles \ in \ 45 \ minutes) =\dfrac{e^{-0.0333\times 45}\times (0.0333 \times 45)^4}{4!}[/tex]

[tex]P( 4 \ motorcyles \ in \ 45 \ minutes) =0.0469[/tex]

Thus; the probability of the 7th motorcycle after the arrival of the third one is = 0.0469

d)

P(at least one other vehicle arrives between 3rd and 4th car arrival)

= 1 - P(no other vehicle arrives between 3rd and 4th car arrival)

The 3rd car arrives at 15 minutes

The 4th car arrives at 20 minutes

The interval between the two = 5 minutes

For Bus:

P(no other vehicle  other vehicle arrives within 5 minutes is)

= [tex]\dfrac{6}{12} = 0.5[/tex]

For motorcycle:

[tex]= \dfrac{2 }{12} = \dfrac{1 }{6}[/tex]

∴

The required probability = [tex]1 - \Bigg ( \dfrac{e^{-0.5 \times 0.5^0}}{0!} \times \dfrac{e^{-1/6}\times (1/6)^0}{0!} \Bigg)[/tex]

= 1- 0.5134

Step-by-step explanation:

1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)

(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)

=-17x^3+4x^2+9-x^2-23x^2-9x-11

=-17x^3+4x^2-x^2-23x^2-9x+9-11

=-17x^3-20x^2-9x-2

2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3

=0-19.73-25x2-12x-3

=-25x^2-12x-22.73

3) - 10.x^3 – 162x^2 – 24x - 4

4) Your problem → 17x^3 - 20x^2 - 9x^2
