Answer:
a.H0: μ =530mL vs. Ha: μ > 530mL
Step-by-step explanation:
-A hypothesis test will be used to provide evidence that the median is more or equal to the stated median value.
#In a normally distributed population, the mean=mode=median:
-The null hypothesis states that the median is equal to the stated value:
-The alternative hypothesis provides evidence that the median value is greater than the stated value:
Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL

Answer
a) PQ = 50
b) PC = 18
PY = 27
c) ZC = 6
ZQ = 18
Explanation
Centroid is a point inside a triangle where all lines drawn from each vertex to the midpoints of opposite side intersect.
Part a
X is the midpoint of PQ. SoPX = XQ.
If PX = 25,
then PQ = 2PX
PQ = 2×25
PQ = 50
Part b
The centroid is alway two thirds away from the vertex.
Also PC = twice CY
PC = 2×9
PC = 18
So, if CY = 9, then PY = 3 × 9
PY = 27
Part c
(i) The centroid is alway two thirds away from the vertex.
If ZC = 12, then CZ =(1/2)QZ
CZ = (1/2) × 12
CZ = 6
(ii) The centroid is alway two thirds away from the vertex.
So, if CZ = 6, then QZ =3 CZ
QZ = 3×6
QZ = 18
Answer:
<J = 45
<L = 45
<M = 90
This is an isosceles right triangle
Step-by-step explanation:
The angles of a triangle add up to 180 degrees
<J + <L + <M = 180
2x+15 + 5x-30 + 6x = 180
Combine like terms
13x -15 = 180
Add 15 to each side
13x-15+15 = 180+15
13x = 195
Divide each side by 13
13x/13 =195/13
x =15
<J =2x+15 = 2*15+15 = 30+15 = 45
<L = 5x-30 = 5*15 -30 = 75-30 = 45
<M = 6*15 = 90
The triangle is a right triangle
Since two angles are equal, that means two sides are equal so it is an isosceles triangle.
This is an isosceles right triangle
That would be written as:
And the step-by-step equation would be:
→ we take the 2 to the right side of the equation and do the IO*
→we solve for 
→ final answer
*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)
