Where’s the figure or nets?
Answer:
Mean = 6.25
Step-by-step explanation:
Data values: 4, 5, 6, 10
Mean = (Sum of all values)/(Number of values)
Mean = (4 + 5 + 6 + 10)/4
Mean = 25/4
Mean = 6.25
The answer is B because its going 90m/s and and in 2 seconds its traveled 180 meters which if you add to 60 gives you 240
P(x<4600) will be obtained as follows:
z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
plugging the values in the equation we get:
z=(4600-4500)/110
z=0.91
thus
P(x<4600)=P(z<0.91)=0.8186
