Answer:

x=-1,2,3

Step-by-step explanation:

f(x) = 0 means we want to find where the graph has a y value of 0

In this example, the graph has a y value of 0 when x =-1 and when x = 2 and when x=3

There are 3 solutions to the equation f(x) = 0

Answer:

-8

2

12

52

Step-by-step explanation:

y = 10x + 2

x = -1, y = 10(-1) + 2 = -8

x - 0, y = 0 + 2 = 2

x = 1, y = 10 + 2 = 12

x = 5, y = 10*5 + 2 = 52

Answer:

k = 3

Step-by-step explanation:

Expanding the first term, we find 1/x at 10(kx)²(1/x)³ = 10k²/x

Expanding the first term, we find 1/x at 8*1⁷(-2/x)¹ = -16/x

Then

10k² - 16 = 74

k = 3

Answer:

5|x|+6>1=7.5

Step-by-step explanation:

i hope this helped

Answer: x >= -6.2

Step-by-step explanation:

Simplify this first by dividing each side by 5

5|x|+6>/5=1/5

|x| + 6 ≥ 0.2

Since this is an absolute value inequality, we need to setup two inequalities

x+6 >= 0.2

x+6 >= -0.2

Solve Equation 1 → x+6 >= 0.2

Subtract - 6 from both sides of the inequality

x+6 - 6>= 0.2 - 6

x ≥ - 5.8

Solution to absolute value equation 1 is

x >= -5.8

Solve Equation 2 → x+6 >= -0.2

Subtract - 6 from both sides of the inequality

x+6 - 6>= -0.2 - 6

x ≥ - 6.2

Answer: 32 sweets

[] The ratio 5:2 goes in the word "toys and sweets" as it is said in the sentence.

-> 5 toys for every 2 sweets

[] We know we will have 16 bags in total. She has exactly enough toys

-> 16 bags in total * 5 toys per bag = 80 toys

[] Because of this, we can multiply 2 by 16 to see how many sweets will be needed.

-> 16 bags in total * 2 sweets per bag = 32 sweets

In this exercise we have to use the derivative knowledge to calculate the value, we have that:

[tex]10x^2/2+2x[/tex]

A derivative of a sum of two functions f(x) and g(x) is a sum of the derivatives of f(x) and g(x). For example, let h(x) = 3x + 5x². A derivative of h(x) is h'(x) = 3 + 10x.

Given that

[tex](10x+2)[/tex]^

We have:

[tex]\int\limits {10x+2} \, dx = 10x^2/2+2x[/tex]

a = adult shirts sold

c = children shirts sold

we know the store sold for every 5 "a", there were 3 "c" sold, so we can say that the adult to children shirts are on a 5 : 3 ratio.

We also know that whatever "c" is, adult shirts sold last weekend was 30 more than that, or namely "c + 30".

Answer:

a = 200 + 0.253 * 50 = 212.65

So the value of height that separates the bottom 60% of data from the top 40% is 212.65. And rounded would be 212.

Step-by-Step Explanation:

The normal distribution is a "probability distribution that is symmetric around the mean, demonstrating that data near the mean occur more frequently than data distant from the mean."

The Z-score is defined as "a numerical measurement used in statistics of a value's relationship to the mean (average) of a set of values, expressed in standard deviations from the mean."

Let X be the random variable that represents how a loan officer scores credit applications from a population, and we know that the distribution for X is provided by:

X ~ N (200,50)

Where u = 200 and o = 50

And the best way to solve this problem is using the normal standard distribution and the z score given by:

Z = x - u/o

For this part we want to find a value a, such that we satisfy this condition:

P (X > a) = 0.40 (a)

P (X<a) = 0.60 (b)

In this example, both conditions are equal.

The z value that meets the criterion with 0.60 of the area on the left and 0.40 of the area on the right is z=0.253, as shown in the attached figure. P(Z0.253)=0.60 and P(z>0.253)=0.4 in this scenario.

Using the prior condition (b), we get:

P (X < a) = P (X-u/a < a - u/o) = 0.6

P (Z < a-u/o) = 0.6

But we know which value of z satisfy the previous equation so then we can do this:

z = 0.253  < a -200/50

And if we solve for a we got

a = 200 + 0.253 * 50 = 212.65

So the value of height that separates the bottom 60% of data from the top 40% is 212.65. And rounded would be 212.7.

Answer:

SteGiven Information:

Average customer arrival = λ =2.3 customers/hour

Average consultant time1 = μ  = 8 minutes/customer

Average consultant time2 = μ  = 10 minutes/customer

Cost of consultants service = $16

Cost of customer waiting time = $25

Required  Information:

Use one consultant with an average service time of 8 minutes/customer or use two consultants, each with average service time of 10 minutes/customer ?

Answer:

it is recommended to use one consultant with an average service time of 8 minutes/customer.

Step-by-step explanation:

Convert the average consultant time to hours/customer

Average consultant time1 = μ  = 60/8 = 7.5 hours/customer

Average consultant time2 = μ  = 60/10 = 6 hours/customer

Single consultant queuing model:

Calculations for one consultant

Average no. of customers waiting for service = Lq = λ²/μ(μ-λ)

Average no. of customers waiting for service = Lq = (2.3)²/7.5(7.5 - 2.5)

Average no. of customers waiting for service = Lq = 0.1356

Average no. of customers in the system = L = Lq + λ/μ

Average no. of customers in the system = L = 0.1356 + 2.3/7.5

Average no. of customers in the system = L = 0.442

Total cost = (customer waiting time cost)*L + consultant service cost

Total cost = $25*0.442 + $16

Total cost = $27.05

Multi consultant queuing model:

Calculations for two consultants

Average no. of customers waiting for service = Lq = ((λ/μ)^k(λμ)/(k -1)(kμ - λ))*P₀

Where k = 2 is the number of consultants and P₀ is the probability that all of the k consultants are idle. The value of P₀  can be found in the tables with λ/μ = 2.3/6 = 0.38 and k = 2,  P₀ ≅ 0.685

Average no. of customers waiting for service = Lq = (2.3/6)²(2.3*6)/(2-1)(2*6 - 2.3)*0.685

Average no. of customers waiting for service = Lq = 0.1431

Average no. of customers in the system = L = Lq + λ/μ

Average no. of customers in the system = L = 0.1431 + 2.3/6

Average no. of customers in the system = L = 0.5264

Total cost = (customer waiting time cost)*L + consultant service cost

Total cost = $25*0.5264 + ($16)*2 (since there are 2 consultants now)

Total cost = $45.16

Conclusion:

Therefore, it is recommended to use one consultant with an average service time of 8 minutes per customer since the total cost is less than the other option.p-by-step explanation:
