Consider this option:
1. formula is: S=0.5*d₁*d₂, where d₁;d₂ - the diagonals of the rhombus.
2. substituting the values into the formula: S=0.5*21*32=336 m².
answer: 336 m².
1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
<h3>What is the Commutative Property of Multiplication?</h3>
The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.
For example, a × b = b × a.
In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
<h3>What is the Commutative Property of Addition?</h3>
The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.
For example, 3 + 2 = 2 + 3.
Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

Answer:
The estimated number of times the spinner will land on 3 is 20.
Step-by-step explanation:
The complete question is:
A four-sided spinner is provided. If Tom spins the spinner 80 times then work out an estimate for the number of times the spinner will land on 3.
Solution:
Assume that the four-sided spinner is unbiased.
That is all the four outcomes are equally likely to be selected.
The probability that the spinner lands on any of the four numbers is:
P(1) = P (2) = P (3) = P (4) = 0.25
It is provided that Tom spins the spinner <em>n</em> = 80 times.
The spinner can land on any of the four numbers independently.
The random variable <em>X</em>, defined as the number of times the spinner lands on 3, follows a Binomial distribution with parameters <em>n</em> = 80 and <em>p</em> = 0.25.
The expected value of <em>X</em> is:


Thus, the estimated number of times the spinner will land on 3 is 20.
