If F(3) then 3=x. So all you would do is substitute 3 in for x
Answer: 122
Explanation: 250 - 5 = 245
(The 5 comes from the president, Vice President, two volunteers, and guess speaker)
245/2 = 122.5
Half a couple cannot attend so the answer would be 122 couples can attend
Answer:
f = 3
Step-by-step explanation:
Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;
From the trigonometry identity, sin(90-theta) = cos theta.
cos(22f-1) = sin (90-(22f-1))
cos(22f-1) = sin (90-22f+1)
cos(22f-1) = sin (91-22f)... 3
substituting eqn 3 into the original equation given, we will have;
sin (91-22f) = sin(7f + 4)
91-22f = 7f+4
7f+22f = 91-4
29f = 87
f = 87/29
f = 3
The answer is 2.5. I hope that helps you.
Answer:
No the evidence is not sufficient
Step-by-step explanation:
From the question we are told that
The sample size is
The sample proportion is
The population proportion is
The Null hypothesis is
The Alternative hypothesis is
The level of significance is given as
The critical value for the level of significance is
Now the test statistic is mathematically evaluated as
substituting values
Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim
