Answer:
- 4 ≤ x < 2
Step-by-step explanation:
The interval is [ - 4, 2 )
The bracket on the left side indicates x can equal - 4
The parenthesis on the right side indicates x cannot equal 2
Thus the inequality represented by the graph is
- 4 ≤ x < 2
Answer:
g(x) = 3.5^x-2
Step-by-step explanation:
because g(0) = 3.5^0-2 = -1 and g(1) = 3.5^1-2 = 1.5
you know that g(x) = y and when x=0 y=-1 on the graph
and when x=1 y=1.5
The answer for the question is C
Answer:
. In other words, there number of girls is 
.
Step-by-step explanation:
The average of a number of measurements is equal to the sum of these measurements over the number of measurements.
.
Rewrite to obtain:
.
For this question:
.
.
Therefore:
.
On the other hand, there are 
boys and girls in total. Using the formula for average:
.
From the question, this average should be equal to 
. In other words:
.
Solve this equation for 
to obtain:
.
.
.
In other words, the number of girls here is .
When putting polynomials in standard form we arrange them from the term with the highest power to the lowest power.
This polynomial would be arranged: -3x^3-5x^2+8x-5
The degree of a polynomial is the power of the highest term so the degree of this polynomial is three.
