Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X [tex]\sim[/tex] uniform(3.17)

[tex]f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17[/tex]

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

[tex]P(X > 5) = \int ^{17}_{5} f(x) \ dx[/tex]

[tex]P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx[/tex]

[tex]P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}[/tex]

[tex]P(X > 5) =\dfrac{1}{14} [17-5][/tex]

[tex]P(X > 5) =\dfrac{12}{14}[/tex]

P(X>5) = 0.857

Answer:

x = - 1 ± i[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

3s² + 8s = 2s - 9 ( subtract 2s - 9 from both sides )

3s² + 6s + 9 = 0

To complete the square

The coefficient of the s² term must be 1, so factor out 3 from 3s² + 6s

3(s² + 2s) + 9 = 0

add/subtract ( half the coefficient of the s- term )² to s² + 2s

3(s² + 2(1)s + 1 - 1) + 9 = 0

3(s + 1)² - 3 + 9 = 0

3(s + 1)² + 6 = 0 ( add 6 to both sides )

3(s + 1)² = - 6 ( divide both sides by 3 )

(s + 1)² = - 2 ( take the square root of both sides )

s + 1 = ± [tex]\sqrt{-2}[/tex] = ± i[tex]\sqrt{2}[/tex] ( subtract 1 from both sides )

s = - 1 ± i[tex]\sqrt{2}[/tex]

Thus

s = - 1 + i[tex]\sqrt{2}[/tex] , s = - 1 - i[tex]\sqrt{2}[/tex]

Answer:

A.) 0.002980

B.) 0.8335

C.) 0.00000000143

Step-by-step explanation:

The problem can be solved using the binomial probability formula :

P(success) p = 0.3

Number of trials (n) = 15

P(x = x) = nCx * p^x * (1 - p)^(n-x)

A) Exactly 10:

P(x = 10) = 15C10 * 0.3^10 * 0.7^5

3003 * 0.3^10 * 0.7^5

= 0.002980

B) between 2 and 6 people :

Using binomial probability calculator to save time

P(2) + p(3) + p(4) + p(5) + p(6)

0.0915 + 0.170 + 0.219 + 0.206 + 0.147

= 0.8335

C.) What is the probability that all 15 will want hot peppers?

P(x = 15) = 15C15 * 0.3^15 * 0.7^0

= 1 * 1.4348907E−8 * 1

Answer:

a. 228- 6th, 489- 17th, 524- 28th, 597- 39th, 623- 50th, 659- 61th, 736- 72th, 777- 83th, 804- 94th

b. 597

Step-by-step explanation:

arrange the data:

228, 489, 524, 597, 623, 659, 736, 777, 804

a. percentile = ((number of items below position + 0.5)/ number of items ) 100

for 228 = (0+0.5/ 9) 100 = 6th

for 489 = (1+0.5/ 9) 100 = 17th

for 524 = (2+0.5/ 9) 100 = 28th

for 597 = (3+0.5/ 9) 100 = 39th

for 623 = (4+0.5/ 9) 100 = 50th

for 659 = (5+0.5/ 9) 100 = 61th

for 736 = (6+0.5/ 9) 100 = 72th

for 777 = (7+0.5/ 9) 100 = 83th

for 804 = (8+0.5/ 9) 100 = 94th

b. The corresponding value for the 40th = number of item( percentile)/ 100

   = 9( 40) / 100 = 3.6 approximately 4th which is 597

Answer:

C) Reflection across the x-axis.

Step-by-step explanation:

From Linear Algebra we define the reflection across the x-axis is for [tex]P(x,y) =(x,y)[/tex]:

[tex]P'(x,y) = (x, -y)[/tex] (1)

If we know that [tex]A(x,y) = (-1, 2)[/tex], [tex]B(x,y) =(-1,5)[/tex], [tex]C(x,y) = (-3, 5)[/tex] and [tex]D(x,y) =(-3, 2)[/tex], then the reflected points are, respectively:

[tex]A'(x,y) = (-1, -2)[/tex]

[tex]B'(x,y) = (-1,-5)[/tex]

[tex]C'(x,y) = (-3,-5)[/tex]

[tex]D'(x,y) = (-3,-2)[/tex]

In consequence, Kim performed a reflection across the x-axis to create triangle A'B'C'D'. The correct answer is C.

This question is based on the reflection of x- axis. Hence the correct answer is C, reflection across the x-axis.

Given:

Transform  rectangle ABCD to rectangle A'B'C'D',

The vertices of rectangle ABCD is A(-1,2) B(-1,5) C(-3,5) D(-3,2).

The vertices of rectangle A'B'C'D is A'(-1,-2) B'(-1,-5) C'(-3,-5) D'(-3,-2).

We need to determined the transformation that Kim perform to create rectangle A'B'C'D.

From Linear Algebra we define the reflection across the x-axis is for,

P(x,y) = (x,y)

P(x,y) = (x,-y)                                .....(1)

It is given that  A(-1,2), B(-1,5), C(-3,5) and D(-3,2).

Therefore from equation (1)  above point becomes,

A'(x,y) = (-1,-2)

B'(x,y) =(-1,-5)

C'(x,y) =(-3,-5)

D'(x,y) =(-3,-2)

Therefore, It is observe that Kim performed a reflection across the x-axis to create triangle A'B'C'D'. Hence the correct answer is C, reflection across the x-axis.

Answer:

Substitution property of equality

Step-by-step explanation:

Given

[tex]4x + 9 = 15[/tex] and [tex]x = 2y + 1[/tex]

Then

[tex]4(2y + 1) + 9 = 15[/tex]

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If [tex]a = b[/tex] then [tex]b = a[/tex]

In other words, both can replace one another.

So if [tex]x = 2y + 1[/tex], then 2y + 1 can be substituted for x in [tex]4x + 9 = 15[/tex]

So:

[tex]4x + 9 = 15[/tex]  becomes

[tex]4(2y + 1) + 9 = 15[/tex]

Hence, it is substitution property of equality

Answer:

The length of rectangle is 7 cm and width is 2 cm.

Step-by-step explanation:

Given that:

Area of rectangle = 14 square centimeters

The length of a rectangle is 3 centimeters less than five times its width.

Let,

L be the length and W be the width of the rectangle.

L = 5W - 3

Area of rectangle = Length * Width

14 = (5W-3)*W

[tex]14=5W^2-3W\\5W^2-3W-14=0[/tex]

Factorizing the equation;

[tex]5W^2-10W+7W-14=0\\5W(W-2)+7(W-2)=0\\(5W+7)(W-2)=0[/tex]

Either,

5W+7 = 0

5W = -7

W = -7/5

Or,

W-2 = 0

W=2

As width of rectangle cannot be negative, therefore,

Width = 2 centimeters

Length = 5(2) -3 = 10-3 = 7

Hence,

The length of rectangle is 7 cm and width is 2 cm.

Answer:

The sale price of the item is  $ 255

Step-by-step explanation:

To determine the amount of discount ( d ) offered by the store, we calculate  

15 %  of the sale price. Thus:

d =  300  ×  15 ÷ 100

d  =  3 00  ×  15  ÷ 1 00  (take the 2 zeros out on both the hundred and 3 hundred)

d  =  3  ×  15

d  =  45

If the amount of discount is known, the sale price ( s ) of the item will be the regular price minus the discount. Hence:

s  =  300  −  45

s  =  255

Hope this helps you! If not sorry!
