Answer: 0.0427
Step-by-step explanation:
Given : The area under the standard normal curve to the left of z = -1.72 is 0.0427
We know that the normal curve is a bell shaped curve that is symmetric such that half of the data falls to the left of the mean (Mean lies at the middle of the curve) and half of data falls to the right.
Now, z=-1.72 lies on the left side and z=1.72 lies right side.
Since, normal curve is symmetric and the magnitude of the values if same , then the area under the standard normal curve to the left of z = -1.72 is equals to the area to the right of z = 1.72 is 0.0427
Therefore, the area under the standard normal curve to the right of z = 1.72 is 0.0427
It is 100 plus 0 plus 9 plus 0.3 plus 0.06 plus 0.001
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
∴
In the diagram, and
m∠A=60° and m∠C=45°
∴
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
From the diagram,
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
=
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
