$1.25 each, write a linear inequality to help determine how many tacos you can buy.
Oy > 1.25x + 2.25
Oy > 2.25x + 1.25

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: Y [tex]\geq[/tex] [tex]\frac{1}{2}[/tex] x+ 20

              Y [tex]\leq[/tex] [tex]\frac{2}{3}[/tex] x+ 80

              X [tex]\geq[/tex] 1,200

             X  [tex]\leq[/tex] 1,850

Step-by-step explanation:

The system of inequalities which represents these constraints is y ≥ 20 + (1/2)x, y ≤ 80 + (2/3)x and 1200 ≤ x ≤ 1850

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represents Sally's monthly paycheck, and y represents her monthly savings.

Hence:

y ≥ 20 + (1/2)x

also:

y ≤ 80 + (2/3)x

and:

1200 ≤ x ≤ 1850

The system of inequalities which represents these constraints is y ≥ 20 + (1/2)x, y ≤ 80 + (2/3)x and 1200 ≤ x ≤ 1850

Answer:

The answer is B 7.5 hours.

Step-by-step explanation:

A. P. E. X

Sydney can clean her house in 7.5 hours.

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.

Here, Monica can clean her house in 5 hours

Monica's efficiency = 1/5

Let, Sydney cleans the house in x hours.

Sydney's efficiency = 1/x

They both together complete their work in 3 hours

Combined efficiency = 1/3

Now, according to question;

1/5 + 1/x = 1/3

(x+5)/5x = 1/3

3x + 15 = 5x

5x - 3x = 15

2x = 15

x = 15/2

x = 7.5

Thus, Sydney can clean her house in 7.5 hours.

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:

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. 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

Step-by-step explanation:

First solve g(x) by replacing x with 4

G(x) = x^2 = 4^2 = 16

Now replace x in f(x) with 16:

F(x) = 2x + 1 = 2(16) + 1 = 32 +1 = 33

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
