This is the commutative property (of addition, but this applies to multiplication as well)It doesn't matter which order the numbers are added in, the same result will be achieved.1+2 = 2+12*4 = 4*2
The TV screen is an illustration of a right triangle
The height of the TV screen is 124.6 cm
<h3>How to calculate the height</h3>
The diagonal is given as:
d = 156 cm
The angle at the top is given as:
Angle = 37 degrees
The height is then calculated using the following cosine ratio
Make h the subject
Evaluate
h = 124.6
Hence, the height of the TV screen is 124.6 cm

Answer:
130.81
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where from the question:
x is the raw score = ?
μ is the population mean = 100
σ is the population standard deviation = 15
We are told in the question that:
Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test.
The top 2% means a score in the 98th percentile
The z score of the 98th percentile = 2.054
Hence:
2.054 = x - 100/15
Cross Multiply
2.054 × 15 = x - 100
30.81 = x - 100
x = 30.81 + 100
x = 130.81
The IQ score that one should have in order to be eligible for Mensa is the score of 130.81
False because y is not shown in the Equation
