Answer: -31
Step-by-step explanation:
[tex]a_{19}[/tex] =5+(19-1)(-2) then our BODMAS method
[tex]a_{19}[/tex] =5+18×(-2)
[tex]a_{19}[/tex] =5-36
[tex]a_{19}[/tex] = -31

Which graph shows the correct solution to the inequality below?
Answers
Answer:
Third Option
Step-by-step explanation:
3x + 18 > 6x - 9
We have to find the value of x for this
Subtract 18 from both sides to leave 3x alone
3x > 6x - 27
Subtract 6x from both sides to be able to find the value of x
-3x > -27
Divide by -3 on both sides
x > 9
The answer would be the third option, since X is anything greater than 9

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answers
Answer:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

(BRAINLIEST IF CORRECT ANSWER) When you roast coffee, it loses 12% of its weight. How much fresh coffee do you need to order to get 14 2/25 lb of roasted coffee?
Answers
==========================================================
Explanation:
14 & 2/25 = 14 + 2/25 = 14 + 0.08 = 14.08
The mixed number 14 & 2/25 is the same as the decimal 14.08
The goal is to end up with 14.08 pounds of coffee.
Let x be the starting amount of coffee, in pounds. It will decrease to 14.08 pounds.
We start with x and decrease by 12%. So we are computing this expression
x - 12% of x = 1x - 0.12x = (1-0.12)x = 0.88x = 88% of x
We can see that if we lose 12%, we keep the remaining 88%
The 0.88x is the final weight.
Set 0.88x equal to the goal of 14.08 and solve for x.
0.88x = 14.08
x = (14.08)/(0.88)
x = 16
You'll need to start off with 16 pounds of coffee if you want to end up with 14.08 pounds after losing that 12%
-------------------
Check:
12% of 16 = 0.12*16 = 1.92
16 - 1.92 = 14.08
The answer is confirmed.
You need to order approximately 4.15 pounds of fresh coffee to get 14 2/25 pounds of roasted coffee after accounting for the 12% weight loss during roasting.
To find out how much fresh coffee you need to order to get 14 2/25 lb of roasted coffee, you'll need to account for the 12% weight loss during the roasting process.
Let's assume "x" represents the amount of fresh coffee (in pounds) you need to order. When this fresh coffee is roasted, it will lose 12% of its weight, leaving you with 100% - 12% = 88% of the original weight as roasted coffee.
Now, set up a proportion to find "x":
(88/100) * x = 14 2/25 lb
First, convert the mixed number 14 2/25 to an improper fraction. It becomes (364/25) lb.
Now, solve the equation for "x":
(88/100) * x = 364/25
To eliminate the fraction, you can multiply both sides of the equation by the reciprocal of (88/100), which is (100/88):
x = (364/25) * (100/88)
Now, simplify the expression:
x = 4.15 lb (rounded to two decimal places)

We know that his first attempt he got 29 questions correct, yet he didn’t pass & the second attempt he got 38 questions correct.
So, If i’m not wrong the percentage increase is 10% [Rounded].
Explanation:
38 - 29 = 9
9 rounded to the nearest tenth is 10%.
Forgive me if I’m wrong, good luck! ^^
Answer:
Step-by-step explanation:
to find percent increase or change :

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.
What domain and range are reasonable for the function?
What do the x-intercept and y-intercept of the graph above represent in this situation?
Answers
Answer:
y = c(f) = 24x so range is 24 domain is 1 the x intercept and y intercept do not count as an adding value in the equation so in order for y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1
Step-by-step explanation:
Given (1, 24) (8, c(f)) = 24 (8) = 192 = (1, 24) (8, 192) Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24 slope = 24 equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.
Answer:
y = c(f) = 24x so range is 24 domain is 1 the x intercept and y intercept do not count as an adding value in the equation so in order for y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1
