BRAINLIEST What is the probability of getting an odd number total when two dice are rolled?
18/36
12/36

36/36
Answer:
18/36
Step-by-step explanation:
There are 36 possible outcomes (6x6). Half of them (18) are odd.
One method of slowing the growth of an insect population without using pesticides is to introduce into the population a number of sterile males that mate with fertile females but produce no offspring. If P represents the number of female insects in a population, S the number of sterile males introduced each generation, and r the population's natural growth rate, then the female population is related to time t by
t =
P+S
P[(r−1)P − S]
dP
Suppose an insect population with 10,000 females grows at a rate of r = 0.10 and 900 sterile males are added in each generation. Evaluate the integral to give an equation relating the female population to time. (Note that the resulting equation cannot be solved explicitly for P.)
The equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the female population is related to time t by;
[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]
Now, to do partial fraction;
(P+S)/P((r-1)P-S) = A/P + B/((r-1)P-S)
P + S = A((r-1)P -S) + PB
if P = 0, then:
A = -1
If (r-1)P - S = 0
p = S/(r-1)
B = 1 + r - 1
B = r
Therefore,
[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]
t = -ln|P| + ln|(r-1)P-S| + 1/r-1 x integral((r-1)/[(r-1)P-S])
t = -ln|P| + ln|(r-1)P-S| + ln|(r-1)P-S|/(r-1)
t = -ln|P| + (r/r-1)ln|(r-1)P-S|
Now substituting known constants then;
t = -ln|P|-1/9(ln|-0.9P - 900|)
t = -ln|P| - 1/9(ln|-0.9P -900|)
t = -ln|P| - 1/9(ln(|(-9/10)(P + 1000)|))
t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)
as P >= 0, ln(P) and ln(P + 1000) doesn’t need abs value
Therefore, the equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

The average length of a baby at birth is 19 inches long. There are 2.54 centimeters in 1 inch. What is the average length of a baby at birth in centimeters.
Answer:
16.46 I don't know
Step-by-step explanation:
Part A
As the company has increased in popularity, it has continued to add employees in all departments. The production facility manager has provided data that shows the relationship between the number of units produced in an hour and the number of workers on the production line during that hour. The data is shown in the table.
Question 1: What type of function would be model the data?
Question 3: Use the graphing tool and best fit function of the tool to write a function that models the data. Round coefficients and constants to the nearest hundredth.
Question 4: Produce about 2300 fidget spinners every hour. How many workers should Marco recommend. Show your work.
9514 1404 393
Answer:
1. a linear model
3. y = 24.97x +417.59
4. 75 workers
Step-by-step explanation:
1. A graph of the data seems to show it nearly follows a straight line. We have used a linear function to model the data.
3. The linear regression model is ...
y = 24.97x +417.59
4. The graphing calculator shows the point (x, y) ≈ (75.4, 2300) is on the line of best fit. Marco should recommend 75 workers for production of 2300 units per hour.
If you want to solve the linear equation ...
2300 = 24.97x +417.59
you get ...
x = (2300 -417.59)/24.97 ≈ 75.4
About 75 workers are needed.

Monday evening, the jar of M & M's© is full. Tuesday, 1 8 of the M & M's are eaten. Wednesday, 1 3 of the M & M's that remained disappeared. Thursday morning, first thing, the jar had 42 M & M's remaining. How many M & M's were in the jar on Monday evening? M & M's
9514 1404 393
Answer:
72 M&Ms
Step-by-step explanation:
We understand the problem to say ...
Monday the jar was fullTuesday the jar was 7/8 full (1/8 gone)Wednesday, the jar was (7/8)(2/3) = 7/12 fullThat 7/12 full condition corresponds to 42 M&Ms being present.
42 = 7/12·full
full = 42(12/7) = 72
There were 72 M&Ms in the jar on Monday evening.
_____
Check
1/8 of 72 = 9 were eaten Tuesday
1/3 of the remaining 63 disappeared on Wednesday. That number is 21, so 63-21 = 42 remained after Wednesday. That is the number seen early Thursday.
There were 72 M & M's in the jar on Monday evening
How to determine the number of M & M's?Let the initial number be x.
When 1/8 of the M & M were eaten on Tuesday, the remaining proportion is:
Remaining = (1 - 1/8) * x
This gives
Remaining = 7x/8
When 1/3 of the M & M disappeared on Wednesday, the remaining proportion is:
Remaining = (1 - 1/3) * 7x/8
This gives
Remaining = 7x/12
On Thursday, the remaining number of M & M is 42.
This means that:
7x/12 = 42
Divide both sides by 7
x/12 = 6
Multiply both sides by 6
x = 72
Hence, there were 72 M & M's in the jar on Monday evening
