The probability we consider factors that decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L

An engine size greater than 3.9 L

Generally, This can be defined as the possibility of an event occurring with respect to other possible outcomes.

Probability looks at calculating the possibility of a given event's occurrence.

To determine the possibility of selecting an engine size greater than 3.9 L, we consider factors than decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L

Hence, the probability we consider factors that decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L

Answer:

No, its not a right angle triangle. check for explanation below ↓

In order to figure whether ABC is a right-angled triangle.

First find the missing side:

22 - 8 - 5

9 cm

so the sides are 5 cm, 8 cm, 9 cm

using the rule:

short side² + short side² = biggest side²

5² + 8² = 9²

25 + 64 = 81

89 = 81

Thus found ABC is not a right-angled triangle.

[tex]AC = 22 - (8+5) = 22 - 13 = 9[/tex]

[tex]9^2 + 13^2 = 81 +169 = 250[/tex]

[tex]22^2 = 484[/tex]

So no, ABC is NOT a right triangle because the pythagorean thoerem fails

Answer:

A =33 units^2

Step-by-step explanation:

The area of a rectangle is found by

A = l*w  where l is the length and w is the width

A = 5.5* 6

A =33 units^2

Part A

Given info:

Because n > 30 is not true, and we don't know the population standard deviation (sigma), this means we must use a T distribution.

The degrees of freedom here are n-1 = 23-1 = 22.

At 90% confidence and the degrees of freedom mentioned, the t critical value is roughly t = 1.717

Use a T distribution table or calculator to determine this. If you don't have a calculator for the task, then you can search out "inverse T calculator" and there are tons of free options to pick from.

The margin of error E is

E = t*s/sqrt(n)

E = 1.717*1.12/sqrt(23)

E = 0.400982

This is approximate and accurate to 6 decimal places.

The confidence interval is going to be xbar plus or minus that E value

L = lower bound = xbar - E = 4.90 - 0.400982 = 4.499018 = 4.50

U = upper bound = xbar + E = 4.90 + 0.400982 = 5.300982 = 5.30

The confidence interval in the format of (L, U) is (4.50, 5.30)

You could also express it as the format L < mu < U and it would be 4.50 < mu < 5.30; however, I'll stick to the first method.

=====================================================

Part B

Since we know sigma = 2.6 is the population standard deviation, we can use a Z distribution now.

At 90% confidence, the z critical value is roughly 1.645; use a table or calculator to determine this.

[tex]n = \left(\frac{z*\sigma}{E}\right)^2\\\\n \approx \left(\frac{1.645*2.6}{0.03}\right)^2\\\\n \approx 20325.254444 \\\\[/tex]

Round this up to the nearest integer to get 20326. For min sample size problems, always round up.

Answer:

Step-by-step explanation:

[tex]S_{n}=\dfrac{n}{2}(2a + (n-1)*d)[/tex]

Here, n- number of terms ; d - common difference ;  a - first term

[tex]S_{8}=12\\\\\dfrac{8}{2}[2a+(8-1)*d]=12\\\\4[2a+7d]=12\\\\2a + 7d = \dfrac{12}{4}\\\\\\2a + 7d = 3 \ -----------------------(i)[/tex]

[tex]S_{16}=56\\\\\dfrac{16}{2}(2a+15d)=56\\\\\\8(2a+15d)=56\\\\2a + 15d=\dfrac{56}{8}\\\\\\[/tex]

2a + 15d = 7 ----------------(ii)

Subtract (i) from equation (ii)

(ii)         2a + 15d = 7

(i)          2a +   7d = 3  

           -      -          -  

                       8d = 4

                          d = 4/8

d = 1/2

Plugin d = 1/2 in equation (i)

[tex]2a +7*\dfrac{1}{2}=3\\\\\\2a = 3 -\dfrac{7}{2}\\\\\\2a =\dfrac{6}{2}-\dfrac{7}{2}\\\\\\2a=\dfrac{-1}{2}\\\\\\a=\dfrac{-1}{2*2}\\\\\\a=\dfrac{-1}{4}[/tex]

Second term =  first term + d

                      [tex]=\dfrac{-1}{4}+\dfrac{1}{2}=\dfrac{-1}{4}+\dfrac{2}{4}=\dfrac{1}{4}[/tex]

[tex]Third \ term =\dfrac{1}{4}+\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{2}{4}=\dfrac{3}{4}\\\\\\Fourth \ term =\dfrac{3}{4}+\dfrac{1}{2}=\dfrac{3}{4}+\dfrac{2}{4}=\dfrac{5}{4}\\\\[/tex]

The y-value of the vertex of the function is 121.

Given

The function is;

[tex]\rm f(x)=-(x +8)(x-14)[/tex]

The vertex of the parabola of a quadratic function is given by;

[tex]\rm \text{The vertex of the parabola}= \dfrac{-b}{2a}[/tex]

Expand the function then solve;

[tex]\rm f(x)=-(x +8)(x-14)\\\\f(x)=-(x(x-14)+8(x-14))\\\\f(x)=-(x^2-14x+8x-112)\\\\f(x)= -x^2+6x+112[/tex]

The y-value of the vertex of the function is;

[tex]\rm \text{The vertex of the parabola}= \dfrac{-b}{2a}\\\\\rm \text{The vertex of the parabola}= \dfrac{-6}{2\times -1}\\\\\rm \text{The vertex of the parabola}= 3[/tex]

Substitute x = 3 into f(x) for corresponding value of y

f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121

Hence, the y-value of the vertex of the function is 121.

Answer:

x= 10

Step-by-step explanation:

We can use the fact that the sum of all angles in a triangle is 180°.

5x +7x +60 = 180

Solve for x, because we have 1 equation with 1 unknown

   5x +7x +60 = 180, combine like terms

       12x + 60 = 180. subtract 60 from both sides of the equation

12x + 60 -60  = 180 -60, combine like terms

                12x = 120, divide both sides by 12

                   x = 10

The loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.

Formula for simple interest = P ×T × R/100

P = Principal amount borrowed ($12,000)

T = Time in various years given

R = Rate of simple interest generated

To determine which loan option that would allow the customer to pay the least amount of interest, the simple interest of each option is calculated below

Simple interest of a 4 years loan = 12000×4×5.2/100

= $2,496

Simple interest of a 5 years loan= 12000×5×4.2/100

= $2,520

Simple interest of a 6 years loan= 12000×6×4.7/100

= $3,384

Simple interest of a 5 years loan= 12000×3×8.4/100

= $ 18,144

Therefore, the loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.
