Answer:
-18y - 18
Step-by-step explanation:
The -2 needs to be distributed into both values in the parenthesis. This will make the equation -8y - 10y - 18. Then, you put the like terms together. This will result in the final equation, -18y - 18
Answer:
Step-by-step explanation:
It must be a trapezoid because a trapezoid has at least one set of parallel sides. Sides of equal length don't mean anything really unless we know hose sides are parallel. I will say sometimes I hear trapezoids ONLY have two parallel sides, while the other two are not, while in other places as long as two are parallel it is a trapezoid. It looks like for this question it is using the definition that at least two parallel sides makes it a trapezoid.
it can be an isosceles trapezoid since it is a type of trapezoid, same with right trapezoid. Basically any special kind of trapezoid
parallelogram because it can have two pairs of parallel lines and have thos parallel sides be equal. So this also means it can be all kinds of parallelograms.
Do you have a list to choose from? because most I pull up don't include right trapezoid at least.
This leaves kite as the only kind of quadrilateral to look at yet, and it specifies no parallel sides. bt your shape need at least one set of them, so it cannot be a kite.
65+56=121, 180-121=59, 59/8=7.375 , so the answer is A
Answer:
Step-by-step explanation:
Given that evolution theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.
Sample size n = 8
df = 8- 1=7
Since population std deviation is not known, and sample size is small we can use only t test
(two tailed test at 5% level of significance)

sd 3.142857143
se 1.111167799
Test statistic = Mean diff/se = 1.595
p = 0.1546
since p >0.05, accept null hypothesis.
There is no evidence to prove that the steady cycle is different from 24 hours.
