Answer:
(-10,11)
Step-by-step explanation:
x-value:
-4-2=-6
-4-6=-10
y-value:
6-1=5
6+5=11
Answer:
The answer is 10
Step-by-step explanation:
If 1 female sockeye lays 10^3
x female sockeyes lay 10^4
Cross multiply
10^3x=10^4×1
10^3x=10^4
Divide both sides by 10^3
x=10
Therefore 10 sockeyes will lay 10^4
First, determine the z-score of 675.
z = (675 - 500) / 100 = 1.75
The z-score of 500 is,
z = 0.
Subtracting the z-scores will give us 1.75. This is equal to 0.9599.
= 0.9599 - 0.5 = 0.4599
Multiplying this to the given number of light bulbs,
n = 0.4599 x 5000 = 2299.5
Therefore, there is approximately 2300 light bulbs expected to last between 500 to 675 hours.
