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

The owner of a (soon to be out of business) restaurant find that an average of 2.3
customers arrive to eat every hour. Find the probability that in any randomly
selected hour, the following number of customers arrive.
a. 0 ______ b. 2 ______ c. 4 ______
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:

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
What is the total number of possible 4-letter arrangements of the letters
m, a, t, h, if each letter is used only once in each arrangement?
Answer: 24
Step-by-step explanation:
The first letter can be any of the four letters, after that, the second now has 3 letter choices as one of them is used for the first letter, the third has 2 and the fourth has 1. So the total possible arrangements is 4 x 3 x 2 x 1 = 24
Aaliyah is making up 16 party bags for her younger sister's birthday party.
Aaliyah wants to put toys and sweets into the bags in the ratio 5:2.
She has 80 toys. How many sweets does she need?
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

Boardman's Department Store sells clothing for children and adults. Last weekend the store sold 5 adult shirt's for every 3 children's shirts.
If the store sold 30 more adult shirts than children's shirts last weekend, how many shirts the the store sell?
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".

A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviation of 50. Find [tex]P_{60}[/tex] , the score which separates the lower 60% from the top 40%.
Please explain!
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.

A baseball team won 8 games and lost 6. If the team continues at this ratio, how many wins will the team have after playing 21 games?
Answer:
12 wins and 9 losses.
Step-by-step explanation:
Because they are winning 57.14% of there games so if 8 out of 14=57.14% then that means if they would have still one at the exact pace then.
12 wins out of 21 would mean they would have one 57.14% of there games.
