Answer:
It is x=−92 .
Step-by-step explanation:
Answer:
B = 34.2°
C = 58.2° or 121.8°
c= 10.6
Step-by-step explanation:
Step 1
Finding c
We calculate c using Pythagoras Theorem
c²= a² + b²
c = √a² + b²
a= 8, b = 7
c = √8² + 7²
c = √64 + 49
c = √(113)
c = 10.630145813
Approximately c = 10.6
Step 2
Find B
We solve this using Sine rule
a/sin A = b/sin B
A = 40°
a = 8
b = 7
Hence,
8/sin 40° = 7/sin B
8 × sin B = sin 40° × 7
sin B = sin 40° × 7/8
B = arc sin (sin 40° × 7/8)
B ≈34.22465°
Approximately = 34.2°
Step 3
We find C
Find B
We solve this using Sine rule
b/sin B = c/sin C
B = 34.2°
b = 7
c = 10.6
C = ?
Hence,
7/sin 34.2° = 10.6/sin C
7 × sin C = sin 34.2 × 10.6
sin C = sin 34.2° × 10.6/7
C = arc sin (sin 34.2° × 10.6/7)
C = arcsin(0.85)
C= 58.211669383
Approximately C = 58.2°
Or = 180 - 58.2
C = 121.8°
To answer (a), we will need to find the Z value for 710 hours and 990 hours.
B) 68% of data lies between one standard deviation of the mean.
850 +70 = 920
850 - 70 = 780
Well...just look at ur graph...it appears that the more fliers u send out, the more customers there are....therefore,when the fliers are increased, the number of new customers will increase because the graph shows a positive association
Answer:
x = 0
Step-by-step explanation:
8 + 6x = 4 * 2
If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides
6x = 0
Divide 6 from both sides
x = 0
To test this, insert the value of x which is 0
8 + 6(0) = 4 * 2
Multiply 6 and 0
8 + 0 = 4 * 2
Multiply 4 and 2
8 + 0 = 8
Add
8 = 8
This equation is true as you can see so x is equal to 0.
Hope this helps.
