Answer: x>-1
Step-by-step explanation:
Dotted line on the axis is covering y infinitely, so theres an inequality on x, and the line is at -1, so x should be > - 1
I think the third one . because since it's exponential function the rate of change is multipling
Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)
Given,
Total number of time coin is flipped = 70
number of time coin lands on tail = 21
<h3>
What is Relative Frequency?</h3>
A relative frequency indicates how often a specific kind of event occurs within the total number of observations. It is a type of frequency that uses percentages, proportions, and fractions.
To find: relative frequency of coin landing on tail.
= 21 / 70
= 3 / 10
Relative frequency = 3 / 10 × 100
= 30%
