The graph translated horizontally two units right, vertically four units down and reflected across x-axis from its parent functi

Keith_Richards [23]

Parent Function: f(x) = x^2

Right 2 units: f(x) = (x^2 - 2)

Down 4 units: f(x) = (x^2 - 2) - 4

Reflection over x-axis: f(x) = - (x^2 -2) + 4

Answer: f(x) = - (x^2 -2) + 4

2, 2 1/2, 1 1\2, 2 whats the next number in the series

DedPeter [7]

<h3>Answer: 1</h3>

Explanation:

The jump from 2 to 2&1/2 is an increase of 1/2

2 + 1/2 = 2 & 1/2

The jump from 2 & 1/2 to 1 & 1/2 is a decrease of 1

(2 & 1/2) - 1 = (2 - 1) & 1/2 = 1 & 1/2

The jump from 1 & 1/2 to 2 is an increase of 1/2

(1 & 1/2) + 1/2 = 1 + (1/2 + 1/2) = 1 + 1 = 2

The pattern seems to be "add 1/2, subtract 1". Assuming this is the case, we would then subtract 1 from the last term we got (2) to get 2-1 = 1

Testing to see if there is evidence that the proportion of US citizens who can name the capital city of Canada is greater than 0

klemol [59]

Answer:

b) B and D and c) A and C

Step-by-step explanation:

The hypotheses would be:

$H_0: p =0.75\\H_a: p >0.75$

(Right tailed test at 5% level)

Sample proportions are

Sample A B C D

Success 31 34 27 38

Proportion p 0.775 0.85 0.675 0.95

Std error

(sqrtpq/n) 0.066 0.056 0.074 0.034

p diff

p-0.75 0.025 0.10 - 0.075 0.20

Z stat

p diff/SE 0.0757 1.77 1.01 5.80

p value 0.469 0.038 0.156 0.000001

we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.

b) Only B and D provide against the null. Because p <0.05

c) A and C provide no evidence for the alternative because p >0.05
