A plan for an executive travelers' club has been developed by an airline on the premise that 5% of its current customers would q

ualify for membership. A random sample of 500 customers yielded 45 who would qualify. (a) Using this data, test at level 0.01 the null hypothesis that the company's premise is correct against the alternative that it is not correct. State the appropriate null and alternative hypotheses. H0: p ≠ 0.05 Ha: p < 0.05 H0: p = 0.05 Ha: p > 0.05 H0: p = 0.05 Ha: p ≠ 0.05 H0: p ≠ 0.05 Ha: p = 0.05 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P-value = State the conclusion in the problem context. Reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the company's premise is incorrect. Reject the null hypothesis. There is sufficient evidence to conclude that the company's premise is incorrect. Do not reject the null hypothesis. There is sufficient evidence to conclude that the company's premise is incorrect.

A=75(125+81/2) how do you this equation? pls Help!!!
Maru [420]
Closing parenthesis is misplaced. Should be: 
<span>A = h(b₁ + b₂)/2 </span>

<span>h = 75 ft </span>
<span>b₁ = 125 ft </span>
<span>b₂ = 81 ft </span>

<span>Then it's just plug & grind: </span>

<span>A = 75(125 + 81)/2 ft² = 75·206/2 ft² = 75·103 ft² = (7500 + 225) ft² = 7725 ft² </span>

<span>If you follow that, it will guide you through any other, similar p</span>

Need help desperately T~T
babunello [35]
As you can see, angle 5 and angle 6 are supplementary.  And angle 5 and angle 3 are congruent because they are alternate interior angles.  

So it will be
x+2 = 180- x+3 
                         move x over from the right to the left
2x+2 = 183
                         move 2 over from the left to the right
2x = 181
                          divide by 2
x= 90.5

and angle 3 and angle 1 are vertical angles so they are congruent.  Using the angle 3 formula to solve for the answer:

90.5+3 =93.5

When angles are congruent, their measures are congruent, therefore, measure of angle 1 is 93.5

What is equation for the line that is perpendicular to y-3=-4(x+2) and passes through the point (-5,7)
jekas [21]

Answer:

y-7=1/4(x+5)

Step-by-step explanation:

y-3=-4(x+2)

y=-4x-8+3

y=-4x-5

-----------

y-y1=m(x-x1)

y-7=m(x-(-5))

y-7=m(x+5)

perpendicular means negative reciprocal of the slope,

so the slope will be 1/4

y-7=1/4(x+5)
