1 inch on the drawing represents 11 feet in the labyrinth middle school.
Step-by-step explanation:
Step 1:
The labyrinth middle school is much larger than the drawing. For 33 inches on the drawing, it is 363 feet on the actual school.
So 33 inches on the drawing is equal to 363 feet in the labyrinth school.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.
In this case, the drawing that Tabitha drew is after scaling and the labyrinth middle school is the measurement before scaling
The scale factor 
So the scale factor is 
. This means that 1 inch on the drawing is 11 feet in the actual school.
Answer:
0.3174
Step-by-step explanation:
Z-score:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the area under the normal curve to the left of Z. Subtracting 1 by the pvalue, we find the area under the normal curve to the right of Z.
Left of z = -1
z = -1 has a pvalue of 0.1587
So the area under the standard normal curve to the left of z = -1 is 0.1587
Right of z = 1
z = 1 has a pvalue of 0.8413
1 - 0.8413 = 0.1587
So the area under the standard normal curve to the right of z = 1 is 0.1587
Left of z = -1 or right of z = 1
0.1587 + 0.1587 = 0.3174
The area is 0.3174
I gotchu. This is pretty simple okay? So when the problem is asking for X and X is inside the triangle, all you have to do is add the other two numbers, which are shown, and subtract it by 180 to get X. For example for problem number 1. You have x that’s inside the triangle, so you add up 47 and 58 which equals to 105 and then take that number and subtract it FROM 180. So the whole equation would be 47+58=105 180-105=75 so X=75. Now for other problems it’s the exact same thing all you have to do is take the other numbers add them up subtract it from 180 and you get X
Answer:
50
Step-by-step explanation:
Use the formula of a trapezoid which is b1 + b2 h/2
8+12=20*5=100/2=50
