Answer:
<h2>z less-than negative 19 or z greater-than 11 </h2>
Step-by-step explanation:
Given the inequality , we are to find the solution set of the inequality. Since the the function is an absolute value, this means that the function will be positive and negative.
For the positive value of the function;
For the negative value of the function we have;
Multiplying both sides of the inequality by -1 will change the sense of the inequality sign;'
Hence the solution sets are OR z less-than negative 19 or z greater-than 11
8a² - 4b + 7a² and 5(3a² - 2b) + 6
First, simplify the expressions.
1) 8a² - 4b + 7a²
Add like terms.
15a² - 4b
2) 5(3a² - 2b) + 6
Distribute 5 by multiplying the number to each terms inside the parenthesis.
15a² - 10b + 6
15a² - 4b ≠ 15a² - 10b + 6
Solution: The expressions are not equivalent.
Its looks like there is no question here. Find x maybe?
the shaded part is a right triangle so we can use Pythagorean theorem
c² = a² + b²
c is the longest side of the or hypotenuse
so I can write it as m² + m² = 9²
m² + m² = 81
2m² = 81
/2 /2
m² = 40.5
√ √
m = √40.5 (well its actually = or - but since it really measurement its +)
~ 6.39
since x is to ms its 2 x 6.39
Answer:
47%
Step-by-step explanation:
Total number of males=14
Total number of females =16
Total number of students =16+14
=30
Probability of a selecting a male student
=47%
