Answer: 163 students
Step-by-step explanation:
First find the percentage of students who were in favor of having school start one hour later based on the sample of 20 students.
= 13/20 * 100%
= 65%
The apply this percentage to the total number of students in school to find your answer:
= 65% * 250 students
= 162.5
= 163 students
The number of students in the school who are in favor of having school start one hour later is; C: 163 students
What is the random sample?We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;
Probability = 13/20 * 100% = 65%
Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;
65% * 250 students = 162.5 ≈ 163 students

Answer:
188.24 (rounded)--- 188.2
Step-by-step explanation:
You want to first find the area of all the the different shapes you have...
you have 2 semicircles A= πr²/2 (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)
you have a rectangle A= b*h
you have a triangle A = b*h/2
Semicircles: A= πr² = (3.14) 4² = (3.14*16) = 50.24
rectangle: A = b*h = 12*8 = 96
Triangle: A = b*h/2 = 12 * 7/2 = 84/2 = 42
then you add them up
50.24 + 96 + 42
= 188.24

c. 36 yards
d. 5,184 yards
Answer:
A- 4 yards
Step-by-step explanation:
Hope this helps!
Have a nice day <3
After changing the unit of 144 inches into yards the number equivalent to 144 inches is 4 yards. Hence option (a) is true.
Given that,
Change the number 144 inches into yards.
Used the concept of measurement unit which stated that,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Since we know that,
1 yards = 36 inches
1 inch = 1/36 yards
So, we can change the number 144 inches into yards,
1 inch = 1/36 yards
144 inches = 144/36 yards
= 4 yards
Therefore, 144 inches is equivalent to 4 inches.
Option (a) is true.

An easy way to figure is to see if all of the numbers in that group can be divided by 6.
In this first one, 9 and 15 are not divisible by 6.
In the second one 6, 12 are multiples ok 6 but there is one more.
In the last one 24 is over the 20 limit.

−4.5◯−4.49
Group of answer choices
Answer:
<
Step-by-step explanation:
-4.49 is greater than -4.5 because it is closer to a positive number.
=====================================================
Explanation:
Think of -4.5 as -4.50, then you would be able to see that -4.50 is further left compared to -4.49 and this makes -4.50 to be smaller than -4.49; therefore, -4.50 < -4.49
Keep in mind that these values are negative, so the more leftward you go, the larger the magnitude of the values will get. For example, -10 is even more to the left so it makes -10 even smaller compared to the other values mentioned. We would be able to say -10 < -4.5 and also -10 < -4.49
Side note: if the values were positive, then 4.50 > 4.49 because 50 > 49. The inequality sign flips when we change everything from positive to negative.

Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than -0.084°C.
P(Z>-0.084)
Answer:
0.53347
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = -0.084 °C
μ is the population mean = 0 °C
σ is the population standard deviation = 1°C
Z score =x - μ/σ
= -0.084 - 0/1
= -0.084
Probability value from Z-Table:
P(x<-0.084) = 0.46653
P(x>-0.084) = 1 - P(x<-0.084) = 0.53347
The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =
is 0.53347
