Conditional statement = if p, then q
contrapositive = if ~q, then ~p
therefore, the answer is
if we go swimming, then there won’t be a lightning storm

Answer:
Null hypothesis:
Alternative hypothesis:
And based on this the best option for this case is:
Ha: μregular > μspecial H0: μregular = μspecial
Step-by-step explanation:
For this case the interest is verify if the true average amount of warpage for that laminate is less than for the regular laminate.
Let's put notation:
represent the true mean for the amount of warpage for the regular laminate
represent the true mean for the amount of warpage for the special laminate
And based on the claim, the correct system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
And based on this the best option for this case is:
Ha: μregular > μspecial H0: μregular = μspecial
Answer:
x=20,y=34
Step-by-step explanation:
x+14=2x-6 (vertically opposite angles)
x-2x = -6-14
-x = -20
x=20
x+14=y (corresponding angles)
20+14=y
y=34
Answer:
88 deg
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. That means that the sum of the measures of angles O and Q is 180 deg.
2x + 2x + 4 = 180
4x + 4 = 180
4x = 176
x = 44
m<O = 2x = 2(44) = 88
Answer: 88 deg
