Answer:
1) Slope =0
2) Slope = 5/7
Step-by-step explanation:
1)
Slope = (-5 + 5)/(9 - 5) = 0/4 = 0
Slope = 0
2)
(-3,-4) and (4,1)
Slope = (1 + 4)/(4 + 3)
Slope = 5/7
Answer: 95% confidence interval would be (0.344,0.456).
Step-by-step explanation:
Since we have given that
n = 295
x = 118
so,
At 95% confidence, z = 1.96
So, margin of error would be
so, 95% confidence interval would be
Hence, 95% confidence interval would be (0.344,0.456).
We can use the Pascal's Triangle to solve this problem. This pascal's triangle is shown in the figure below. To build the triangle, begin with the number 1 at the top, then continue placing numbers below it in a triangular pattern. In this way, each number are the numbers directly above added together. So, the expression:
Can be extended as follows, for n = 10:
So, the 8th term of the binomial expansion is:
Answer:
D
Step-by-step explanation:
Answer:
y = 8(x + 2)^2 + -15
Step-by-step explanation:
Factor out the leading coefficient.
y = 8(x2 + 4x) + 17
Form a perfect-square trinomial.
y = 8(x2 + 4x + 4) + 17 + -32
Write in vertex form.
y = 8(x + 2)^2 + -15
