In a random survey of U. S. adults in 2007, 57% said it is unlikely that life exists on other planets. You believe the proportion is greater than 57%. In a sample of 150 adults, 78 said it is unlikely that life exists on other planets. At a significance level of 0.05, can you support the claim? A) Write the null and alternative hypotheses.

B) Check to see if conditions are met.

C) Identify the test statistic and the P-value rounded to the nearest thousandth.

D) State the conclusion in the context of the problem.

C) Identify the test statistic and the P-value rounded to the nearest thousandth

Step-by-step explanation:

because 1.2 isnt half of 6 duh

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
