Answer:
x= 12
Step-by-step explanation:
180° = (3x - 6) + (8x + 4) + 50° because all interior angles of a triangle add up to 180°
180° = 11x +48°
11x = 132°
x = 12
Answer:
a) yes
b) no
c) no
Step-by-step explanation:
a) The percentage change from 12 to 15 is ...
(15/12 -1)·100% = 1/4·100% = 25% . . . . between 20% and 30%
__
b) The height increased by 61-52 = 9 inches. 20% of 52 inches is 10.4 inches, so the increase was less than 20%.
__
c) The increase was negative, so was not between two positive values.
___
In summary ...
a) yes, 25% is between 20% and 30%
b) no, 17.3% is NOT between 20% and 30%
c) no, -33.3% is NOT between 20% and 30%
_____
A percentage change can be calculated from ...
((new value)/(old value) -1) × 100%
Answer is <span>D.
A and D
A = 2(6+2) = 16
D = 2(4+3) = 16
both have perimeters = 16</span>
The value of the probability P(A and B) is 0.12
<h3>How to determine the probability?</h3>
The given parameters are
P(A) = 0.40
P(B) = 0.30
Given that the events are independent events;, we have:
P(A and B) = P(A) * P(B)
So, we have:
P(A and B) = 0.40 * 0.30
Evaluate
P(A and B) = 0.12
Hence, the value of the probability P(A and B) is 0.12
