Answer:
Step-by-step explanation:
Basically you can see it hits -5 as a minimum and that means there is 2 there and then -1 and then hits 4 3 times and then 7
So your answer is x=-5 with multiplicity of 2 x=-1 and x=4 with multiplicity of 3 and x=7 once.
Answer:
c. an observed difference is 0.12 and P < 0.0001
Step-by-step explanation:
Let p1 be the proportion of the students who received musical instruction received a passing grade
Let p2 be the proportion of the students who didn't receive musical instruction received a passing grade
Null and Alternative hypotheses are:
- : p1-p2=0
- : p1-p2≠0
Test statistic can be found using the equation:
where
- p1 is the sample proportion of the students who received musical instruction received a passing grade ()
- p2 is the sample proportion of the students who didn't receive musical instruction received a passing grade ()
- p is the pool proportion of p1 and p2 ()
- n1 is the sample size of the students who received musical instruction (3239)
- n2 is the sample size of the students who didn't receive musical instruction (2787)
Thus, ≈ 11.84 gives p-value < 0.0001
Observed difference is: 0.87-0.75=0.12
Answer:
x² - 9
Step-by-step explanation:
(x + 3)(x - 3)
= x(x - 3) + 3(x - 3) Distributive property
= x² - 3x + 3x - 9
= x² +( -3x + 3x) - 9 Associative
= x² + 0x - 9 Addition
= x² - 9
Answer: x = 4
Step-by-step explanation:
Given : A coordinate grid with 2 lines.
One line, labeled f(x) passing through (- 3, 3), (0, 3), and the point (4, 3). (i)
The other line is labeled g(x) and passes through (- 4, -3), (0, 0), and the point (4, 3). (ii)
We generally denote x values as input values and y values as output values.
From (i) and (ii), the common point on both lines = (4,3)
Here, input value = 4
Output value = 3
Hence, the input value produces the same output value for the two functions on the graph : x=4
