The area of the pocket park will be given by:
Area=1/2sin θ (ab)
θ=40°
a=100 yds
b=53.2 yds
thus
Area=1/2×sin 40×(100×53.2)
Area=1,709.82 sq. yds
No because if you plug in the ordered pair you would get 9=-2-7 which equals -9 making -9 and 9 unequal means (-2,9) is not a solution.
Answer:
The proportion of these light bulbs that will last less than the advertised time is 18.94% or 0.1894
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x - mean)/SD
= (1500-1550)/57 = -50/57 = -0.88
So the proportion we will need to find is;
P( z < -0.88)
We shall use the standard score table for this and our answer from the table is 0.1894 which is same as 18.94%
Answer: Option 'E' is correct.
Step-by-step explanation:
Since we have given that
If the length of one piece of rope is 2.8 meters shorter than the length of the other.
Let the length of first piece be 'x'.
Let the length of second piece be 'x-2.8'
Total length of rope = 20.6
So, According to question, it becomes,
So, the greatest number of the length of part of rope is 11.7 m.
Hence, Option 'E' is correct.
Answer:
$9.45
Step-by-step explanation:
1 - 0.12 = 0.88
12.60 * 0.88 = 9.45
You save $3.15
