Answer:
Range is (-8,00)
Step-by-step explanation:
To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
2.4 miles
cross multiple 3/25 x x/20
25x=60
x = 60/25 simplified is 2 2/5 or 2.4 miles
