The number of significant figures is the number of digits that is believed to be correct by the person doing the measuring.
<h3>What are significant figures?</h3>
It should be noted that significant figures are the number of digits in a value, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
Precision refers to how closely individual measurements agree with each other. In any measurement, the number of significant figures is critical.

Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
Answer:
look below
Step-by-step explanation:
The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:
P of picking card with star:
25/50=0.5
Card with square:
15/50=3/10=0.3
Card with circle: 10/50=1/5=0.2
We can then put these values into parts a,b,c, and d:
a) 3/10 chance or 30%
b) 1/5 chance or 20%
c) 1/2+1/5=7/10 chance or 70%
d) 1-0.3-0.2=1/2 chance or 50%
9.23 is less than 9.32 because .32 is more than .23
<u><em>Answer:</em></u>
x = -31.5
<u><em>Explanation:</em></u>
We are given that the quotient of x and -1.5 is 21
<u>This means that:</u>
To get the value of x, we will multiply both sides of the equation by -1.5
<u>This means that:</u>
x = -31.5
<u>Note that</u> the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)
Hope this helps :)
