Eddie's Electric charges $90 per hour plus a $50 traveling fee. Which equation models this scenarlo?​

Answer:

may be 10

Step-by-step explanation:

as 1000/10=100

therefore

100/10=10

Answer:

y = 0, -2

Step-by-step explanation:

Factor out the common term 3y.

[tex]3y( {y}^{2} + 4y + 4) = 0[/tex]

Rewrite y² + 4y + 4 in the form of a² + 2ab + b², where a = y and b = 2.

[tex]3y( {y}^{2} + 2(y)(2) + {2}^{2} ) = 0[/tex]

Use square sum: (a + b)² = a² + 2ab + b².

[tex]3y(y + 2) ^{2} = 0[/tex]

solve for y.

y = 0, -2.

therefor, the answer for this equation is 0, - 2.

[tex] \displaystyle \: x_{ \text{lesser}}= - 18.16\\ x _{ \text{greater}} = - 11.84[/tex]

Step-by-step explanation:

we are given a equation

we want to figure out x

add 10 to both sides:

[tex] \displaystyle \: (x + 15 {)}^{2} = 10[/tex]

square root both sides:

remember that,

[tex] \displaystyle \: a = \pm \sqrt{b} [/tex]

by that

[tex] \displaystyle \: x + 15 = \pm\sqrt{10} [/tex]

cancel 15 from both sides:

[tex] \displaystyle \: x = \pm\sqrt{10} - 15[/tex]

so

[tex] \displaystyle \: x_{ \text{lesser}}= - 18.16\\ x _{ \text{greater}} = - 11.84[/tex]

8624.03

Step-by-step explanation:

Answer:

8624.03

Step-by-step explanation:

Alright, lets simplify.

8 x 1000 is 8000

6 x 100 is 600

2 x 10 is 20

4 x 1 is 4

3 x 1/100 is 3/100 or 0.03

if we add them all up, we get 8624.03

Answer:

A

Step-by-step explanation:

Area=L+L+B+B

L=2

B=1

So, L+L+B+B=6

204/6=34

So, it's 34 ft, which is A.

Answer:

33 girls

Step-by-step explanation:

This is the answer because:

1) 3/4 of 44 is 33 because 1/2 of 44 is 11

               a) 11 x 3 = 33

Hope this helps! :)

Answer:

Step-by-step explanation:

6000(1.02)³⁶​ = 2.1 × 10¹³⁶

Answer and Step-by-step explanation:

To solve, we have to plug in the x and y values given to us into the equation.

5(5) - 3(-1)

Simplify

25 - -3

The negatives cancel each other, leading to becoming positive.

25 + 3

Add

28

The value of the expression with the given values for x and y is 28.

Zero is Soo's miserly number. It won't give the number four

Answer:

the steady-state percentage of residents who are uninvolved is 0.5

Step-by-step explanation:

 Given the data in the question;

let N represent total number of people in the dormitory

I represent  people involved in a relationship

and U represent people uninvolved in a relationship.

so

N = I + U

I = N - U ------ let this be equation 1

Rate of Uninvolved = U/N

now, given that rate of break ups B = 15% every month = 0.15

rate of entering into relationship  R = 15% every month = 0.15

Now, the steady state condition is;

RU = BI ------- let this be equation 2

such that uninvolved rate is constant.

we input equation 1 into 2;

RU = B( N - U  )

we divide both sides by N

RU/N = B( N/N - U/N  )

RU/N = B( 1 - U/N  )

U/N = B / (B + R)

so we substitute

U/N = 0.15 / (0.15 + 0.15)

U/N = 0.15 / 0.3

U/N = 0.5

Therefore, the steady-state percentage of residents who are uninvolved is 0.5

Answer:

4. The strength of class V is 300

5. Meenakshi bought a TV for Rc 46,000

Step-by-step explanation:

4. To round to the nearest hundred, check the number in the 'tens'. If its five or greater, round up, and if its lower than 5, round down. In this case it was 7, so we rounded up to 300.

5. To round to the nearest thousand, check the number in the 'hundreds'. If its five or greater, round up, and if its lower than 5, round down. In this case it was 3, so we rounded down to 46,000.

Answer:

0.0367 = 3.67% probability that exactly 6 patients will die

Step-by-step explanation:

The patients are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question, we have that:

20 patients means that [tex]N = 20[/tex]

Sample of 8 means that [tex]n = 8[/tex]

9 have the heart problem, so [tex]k = 9[/tex]

What is the probability that exactly 6 patients will die?

This is P(X = 6).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 6) = h(6,20,8,9) = \frac{C_{9,6}*C_{11,2}}{C_{20,8}} = 0.0367[/tex]

0.0367 = 3.67% probability that exactly 6 patients will die

Answer:3/2

Step-by-step explanation:

Answer:

C: left tailed

Step-by-step explanation:

In two tailed hypothesis, the alternative hypothesis is when mean can either be lesser or greater than the given value. Usually uses the symbol ≠.

In right tailed, the alternative hypothesis is when the mean is greater than the given value.

In left tailed, the alternative hypothesis is when the mean is lesser than the given value.

In this question, the hypothesis test to be performed is to determine if the average amount of time spent watching television per week has decreased from the given value of 21.6 hours.

Thus, it is left tailed test.

Answer:

1 package of dog bones = 4.875

Answer:

  9%

Step-by-step explanation:

The interest earned is ...

  I = Prt . . . . . principal P at annual rate r for t years

Solving for r, we find ...

  r = I/(Pt) = $540/($3000×2) = 0.09 = 9%

The interest rate on Beka's loan is 9%.
