Olivia spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -1.9°F. Between 9am and noon, the temperature rose 10.1°F. Between noon and 3pm, the temperature went down 1.3°F. Between 3pm and 6pm, the temperature dropped 5.1°F. What was the temperature at 6pm?
Answers
The temperature at 6pm was 1.8°F.
To find the temperature at 6pm, we need to add up the changes in temperature from 9am to 6pm.
From 9am to noon, the temperature rose 10.1°F, so at noon, the temperature was:
-1.9°F + 10.1°F = 8.2°F
From noon to 3pm, the temperature went down 1.3°F, so at 3pm, the temperature was:
8.2°F - 1.3°F = 6.9°F
From 3pm to 6pm, the temperature dropped 5.1°F, so at 6pm, the temperature was:
6.9°F - 5.1°F = 1.8°F
Therefore, the temperature at 6pm was 1.8°F.
At 9 am, the temperature was -1.9°F. Between 9am and noon, it rose by 10.1°F, so at noon the temperature was -1.9 + 10.1 = 8.2°F. Between noon and 3pm, the temperature went down 1.3°F, making it 8.2 - 1.3 = 6.9°F at 3pm. Finally, between 3pm and 6pm, the temperature dropped 5.1°F, so at 6pm the temperature was 6.9 - 5.1 = 1.8°F.

A person places $85800 in an investment account earning an annual rate of 8. 5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account int years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 9 years.
Answers
If the person places $85800 in investment account at the rate of 8.5% compounded continuously , then the amount of money in the account after 9 years is $184384 .
the amount of investment made is(P) = $85800 ,
the annual rate of interest for the investment is (r) = 8.5% = 0.085,
the time after which the amount is calculated is (t) = 9 years ,
let the value after t years be = V ,
the formula used to calculate the final amount is ⇒ V = P\(e^{r \times t}\)
Substituting the values ,
we get ,
V = 85800 × \(e^{0.085 \times 9}\)
V = 85800 × 2.14899
V = 184383.342
V ≈ 184384
Therefore , the amount of money in the account after 9 years will be $184384 .

do i p
Answers
The value of the rate of growth in Japan is - 0.55.
From the question above, :Birth rate = 7.7 per thousand
Death rate = 9.8 per thousand
Net migration = 0.55 per thousand
The rate of growth can be calculated using the following formula:
r = (birth rate - death rate) + net migration
Where,r = rate of growth
birth rate = number of live births per thousand in a population in a given year
death rate = number of deaths per thousand in a population in a given year
net migration = the difference between the number of people moving into a country (immigrants) and the number of people leaving a country (emigrants) per thousand in a given year
Putting the values in the formula we get,r = (7.7 - 9.8) + 0.55r = - 1.1 + 0.55r = - 0.55.
Therefore, the rate of growth in Japan is - 0.55.

2) a scatterplot with an even number of points in which the correct regression line passes directly through 0 of the points
3) a scatterplot with an odd number of points in which the correct regression line passes directly through 1 of the points

Step-by-step explanation:
From what Serena said about regression line drawn correctly in a scatter plot, looking at the options, the correct answer is option 1. This is due to the fact that If there is an odd number, and the regression line touches none of them, then there must at least be one more point located on one side of the line when compared to the point on the other side of the line.

Answers
Answer:

To determine the quantity of snack mix Jared guest ate, we multiply the quantity of snack mix the guest ate by the quantity of snack mix Jared made. i.e we determine \(\frac{2}{3}of12\frac{3}{4}\) by multiplying both fractions together
quantity of snack mix Jared guest ate = \(\frac{2}{3}of12\frac{3}{4}=\frac{2}{3}*12\frac{3}{4}=\frac{2}{3}*\frac{51}{4}=\frac{17}{2} =8\frac{1}{2}\)
