A is directly proportional to b. When a is 6, b is 72. Find b when a is 8. 3

adelina 88 [10]

Answer:

a) "K" is proportional Constant K= 0.0833

b) The value of b = 99.639

Step-by-step explanation:

Explanation :-

Given 'a' is directly proportional to 'b'

a ∝ b

a = k b ....(i)

where "K" is proportional Constant

Case(i):-

when a =6 and b=72

a = k b

⇒ 6 = k (72)

⇒ $K = \frac{6}{72} = \frac{1}{12} = 0.0833$

Case(ii):-

Given a = 8.3

a = k b

⇒ 8.3 = 0.0833 ×b

⇒ $b = \frac{8.3}{0.0833} = 99.639$

Final answer:-

a)"K" is proportional Constant K= 0.0833

b) The value of b = 99.639

Please help!!! I don’t understand

cluponka [151]

The first statement CA || DB , E is midpoint is GIVEN to you. That is the reason that statement can be made. It is GIVEN.

The second statement I would make is that ∠ACE = ∠DBE and ∠CAE = ∠EDB because Alternate interior Angles of parallel line CA || BD. You can also say ∠DEB = ∠CEA due to vertical angles being equal.

The third statement should be that AE = ED because E is the midpoint of AD.

The fourth statement is that the triangles are congruent, this is because ASA . Angle-Side-Angle are equal.

If a sample has 60 participants and is a proportion of p=0.25 of its population, then what is the standard deviation of the samp

hjlf

Answer:

If a normal distribution is considered, a standard deviation (SD) is accounted for 34% (0.34 of population).

60 participants <=> p = 0.25

SD <=> p = 0.34

=> SD = 60 x 0.34/0.25 = 81.6 = ~82 participants.

Hope this helps!
