Answer:
For the first question the correct form would be B. It would be 6(p-3)=42. For the second question the answer would be 10.
Step-by-step explanation:
For the first question B is correct because it's 3 dollars off which would be -3.
For the second question you would multiply 6 with p and 6 with -3. This would equal to 6p-18. This would make the equation 6p-18=42. You would then add 18 to 42, which equals 60. Finally you would divide 60 by 6, which equals 10, which is your answer.
It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.
<h3>What is the null hypothesis?</h3>
It should be noted that null and alternate hypothesis are written based on the population parameter.
From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:
= 1/4 = 0.25
Therefore, the null hypothesis is H: p = 0.25 and the alternative hypothesis is H : p > 0.25.

Answer:
Step-by-step explanation:
Similar shapes must have corresponding sides in a constant proportion. Therefore, we can set up the following equation and solve for 
:
(divide corresponding sides)
