Answer:
- <u>Quantitative.</u>
- <u>Discrete.</u>
- <u>Interval Scale.</u>
Step-by-step explanation:
- The IQ scores are measured numerically. This makes it quantitative data. Quantitative data provide numerical measures which can be used to perform arithmetric operations such as addition, subtraction, multiplication and division. Results from these kind of data can be used to provide meaningful and explanatory results to certain phenomena.
- IQ scores are discrete because they are always expressed as integers. that is in whole numbers and not in fractions e.g 100, 120, 60.
- The level of measurement is on an interval scale because the difference between values have meanings. Larger values mean higher IQ. for example, the difference in IQ numbers between two people for represents something real.
Answer: See Below
<u>Step-by-step explanation:</u>
NOTES
45°- 45° - 90° sides are a - a - a√2
30° - 60° - 90° sides are b - b√3 - 2b
Solve for "a" <em>or "b"</em> and then plug that value in to find the missing side lengths.
c) 30° - 60° - 90°
30° : b = x → 5√3 = x
60° : b√3 = 15 → b = 5√3
90° : 2b = y → 10√3 = y
d) 30° - 60° - 90°
30° : b = x → 12 = x
60° : b√3 = y → 12√3 = y
90° : 2b = 24 → b = 12
e) 45° - 45° - 90°
45° : a = 5√2
45° : a = x → 5√2 = x
90° : a√2 = y → 10 = y
f) 30° - 60° - 90°
30° : b = y → 5 = y
60° : b√3 = 5√3 → b = 5
90° : 2b = x → 10 = x
g) 30° - 60° - 90°
30° : b = x → 3√3 = x
60° : b√3 = 9 → b = 3√3
90° : 2b = y → 6√3 = y
h) 45° - 45° - 90°
45° : a = 3
45° : a = (1/2)y → 3 = (1/2)y → 6 = y
90° : a√2 = x → 3√2 = x
Carlos driving time = Xh, Maria driving time = Yh.
55m/h*Xh + 47m/h*Yh = 197m
Together, they both drove 3,8 hours, so Carlos drove 3,8 hours minus the time Maria drove;
55m/h*(3,8h-Yh)+47m/h*Yh = 197m
55m/h*3,8h - 55m/h*Yh + 47m/h*Yh = 197m
<span>209m - 8m/h*Yh = 197m
8mY = 209m - 197m
8mY = 12m
Y = 12m/8m
Y = 1,5
</span>The correct answer is 1,5 hours.
The baker is unable to fill ten platters of cupcakes without having 2 vanilla cupcakes left over. While 80 is divisible by 10 and comes out evenly, 72 on the other hand will leaving you with a decimal.
The greatest number of platters the baker can make without having any cupcakes left over are 8 platters. 8 is the greatest common factor between 80 and 72, and will give you 10 chocolate cupcakes and 9 vanilla cupcakes per platter.
