Answer:

x=90: y =43

Step-by-step explanation:

Given is a triangle. In ABC, AB = AC is given. also angle C = 47 is given.

AD is angle bisector of angle A

Since two sides are equal, ABC is isosceles. We have angle C = angle B

Hence angle B = 47 degrees.

Angle A = 180-(B+C) = 180-94 = 86

So angle y = 1/2 (86) = 43

Consider triangle BAD.

We have got two angles as 47 and 43.

Hence third angle is 180-(47+43) = 90

So x=90, y = 43

Looking at the triangle we see the angles:

58, x

We also see a right angle, therefore you now have:

90, 58, 0

All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.

90 + 58 = 148

180 - 148 = 32

Therefore, x = 32 or C

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:

$Mean=Mode=Median=\mu$

-The null hypothesis states that the median is equal to the stated value:

$H_o:\mu=530 \ mL$

-The alternative hypothesis provides evidence that the median value is greater than the stated value:

$H_a:\mu>530\ mL$

Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL
