The time at which changeover to sleet can occur is 10:30 Am.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given that the temperature outside is dropping at a rate of 1.5 °F each hour. Also, Currently, the temperature is 53 °F and the time is 8:30 Am. Therefore, we can write,
32 °F = 53 °F - (1.5 °F)x
32 = 53 - 1.5x
32 - 53 = -1.5x
-21 = -1.5x
x = -21 / -1.5
x = 14
Thus, it will take 14 hours for a changeover. Now, since the base time is 8:30 Am, therefore, the time after 14 hours will be 10:30 Am.
Hence, the time at which changeover to sleet can occur is 10:30 Am.

6.7x10 =
Answer: 67
Step-by-step explanation:
When you multiply with numbers like 10, 100, 1000, 10000, and so on you just have too right or left (division : left)(multiplication : right) according to the zero's. Like 100 has 2 zero's so then if you're multiplying with that you will go 2 to the right, and dividing you will go 2 to the left. Lets apply the same logic here, the question is 6.7 x 10, 10 has 1 zero and we are multiplying here so then, we have to go to the right, so 6.7 will become 67.

find the population variance of: 4 6 8 9 9
round to the nearest hundredth
Answer:
Step-by-step explanation:
To find the population variance, we first need the mean:
[tex]\bar{x}=\frac{4+6+8+9+9}{5}=\frac{36}{5}=7.2[/tex] so the mean is 7.2. To find the population variance (which is almost exactly the same as the sample variance except for a small difference in the denominators of the formula) we have to take each number minus the mean, and then square the difference. Add together all these squared numbers and then divide by the number of numbers. Like this:
[tex](4-7.2)^2=10.24\\(6-7.2)^2=1.44\\(8-7.2)^2=.64\\(9-7.2)^2=3.24\\(9-7.2)^2=3.24[/tex]
Add together those numbers and divide them by 5:
[tex]\sigma=\frac{10.24+1.44+.64+3.24+3.24}{5}=\frac{18.8}{5}=3.76[/tex]
