Answer: 60
Step-by-step explanation:
Area = ½base × height
600 = ½b × 20
600/20 = ½b
Base = 30 × 2
A=1 B=2 C=3 Yes it would work for all because its using the commutative property.
Answer:
6x - 13y
Step-by-step explanation:
5(2x - 2y) - (4x + 3y)
10x - 10y - 4x - 3y
10x - 4x - 10y - 3y
6x - 13y
Answer:
Step-by-step explanation:
given that certain tubes manufactured by a company have a mean lifetime of 800 hours and a standard deviation of 60 hours.
Sample size n =16
Std error of sample mean = 
x bar follows N(800, 15)
the probability that a random sample of 16 tubes taken from the group will have a mean lifetime
(a) between 790 and 810 hours,
=
(b) less than 785 hours
, (c) more than 820 hours,
(d) between 770 and 830 hours
=
Answer:
58 inches
<u>Step-by-step explanation:</u>
Perimeter means the sum of length of all sides of a figure.
So, the perimeter of this triangle would also be the sum of the length of its sides.
It has 3 sides.
19 in, 16 in and 23 in.
So, its perimeter equals 19 + 16+ 23
which equals 58 inches!
So, the perimeter would be 58 inches.!
