Answer:
the answer is option c
c)60
Step-by-step explanation:
From the given statement 2 × 3 mixed factorial design where 2 is a factor which is within the subject and
3 is the subject between the subject
then observation per cell where participants will need is 3* 20 = 60 because 3 is the factor between the subject.
Answer:
a = 25°
Step-by-step explanation:
60° and 3a - 15° are congruent because they are corresponding.
60 = 3a - 15
75 = 3a
a = 25°

For the given figure, x = 34.640 units.
Step-by-step explanation:
Step 1:
The formulae needed to solve this question are:
The triangle containing x can be split into two right-angled triangles.
So the hypotenuse of the triangle containing the length x and the already given right angle triangle's hypotenuse is the same length.
Step 2:
First, we calculate the hypotenuse of the given triangle.
The angle of the triangle is 45°, the adjacent side's length = 10√3 units. Assume the hypotenuse's length to be a units.
units.
Step 3:
For the split triangle, we have the angle as 45°, the opposite side measuring units (only half of x is in each triangle) and the hypotenuse measuring 24.498 units.
So x measures 34.640 units.
A cord: and the longest cord in a circle is the diameter , so a diameter is a special case of cord.
Answer: I'm not entirely sure but i think its the last one! How this helps!
Step-by-step explanation:
I followed the information on the graph and the one with a 7.2 circumference had a 22.66 cm diameter!
