Answer:
Step-by-step explanation:
"two over three (4x + 9)":
<em>use the distributive property </em><em>a(b+c) = ab + ac</em>
I believe the answer is 12. I hope this helps you and have a great day!
Let the amount of adult tickets sold be x
Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:
x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225
Therefore, the amount of adult tickets sold is 225
-4 (-5x+4w-1)
Multiply -4 by everything in the parenthesis:-4 * -5w = 20w
-4 * 4w = -16w
-4 * -1 = 4
20w - 16w + 4
And if you need it more simplified:
4w + 4
Answer:
0.001
Step-by-step explanation:
Here, the aim is to support the null hypothesis, Ha. Where Ha: p > 0.5. Which means we are to reject null hypothesis H0. Where H0: p = 0.5.
The higher the pvalue, the higher the evidence of success. We know If the pvalue is less than level of significance, the null hypothesis H0 is rejected.
Hence the smallest possible value 0.001 is preferred as the pvalue because it corresponds to the sample evidence that most strongly supports the alternative hypothesis that the method is effective
