Answer:
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%
Step-by-step explanation:
The null hypothesis is the problem statement and the alternate hypothesis is a contradiction of null hypothesis
Hence,
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%
Answer:
B
Step-by-step explanation:
The slope intercept form for a line is y=mx+b, where m is the slope and b is the y intercept. Since this line rises 9 units for every 1 it moves to the right, it has a slope of 9. Since it goes through the origin, it also has a y intercept of 0. Therefore, the equation of this line is y=9x, or answer choice B. Hope this helps!
The expression is simplified to 10x² + 48x + 3 =0
<h3>How to determine the value</h3>
Given the expression as;
We take the numerators have the same base, then we have;
(4x+1)(x+2) + 4(x(x+ 15) = -2x² + 21x - 1
expand the bracket
4x² + 8x + x + 2 + 4(x² + 15x) = -2x² + 21x - 1
4x² + 8x + x + 2 + 4x² + 60x = -2x² + 21x - 1
collect like terms
4x² + 4x² + 2x² + 8x + x + 60x - 21x = - 1 - 2
Add or subtract like terms
10x² + 48x = -3
Make into a quadratic equation
10x² + 48x + 3 =0
Thus, the expression is simplified to 10x² + 48x + 3 =0

Answer:
x>-1
Step-by-step explanation:
-1 is not greater than 1 so its not any of the right answers. So were left with the left answers. The arrow starts at -1 so it can't be 1 so its x>-1
