Answer:
Step-by-step explanation:
The answer is 7, Because if AC is 12 the radius would be half of that and you would get 7.
Hope I helped.
Answer:
You said what now?
Step-by-step explanation:
Honestly i agree with Nd12217 z is the answer to 136 x 150
Nevermind the answer is wrong
Using the z-distribution, as we are working with a proportion, the 95% confidence interval for the proportion of consumers who would buy the product at it's proposed price is (0.3016, 0.3830).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
179 out of 523 members indicated they would buy the new product at the proposed price, hence:

Then the bounds of the interval are found as follows:

Answer:
68°
Step-by-step explanation:
The triangle containing the 79° angle is isosceles. That means the other base angle is also 79°. The central angle is ...
V = 180° -2(79°) = 22°
__
Angle X is the other acute angle in right triangle VWX, so has measure ...
X = 90° -22° = 68°
_____
<em>Additional comment</em>
A tangent makes a right angle with the radius to the point of tangency. W is the point of tangency, so angle VWX is a right angle.
