Answer:
y = 2/5x + 4
Step-by-step explanation:
Points on the line:
(0,4) and (5,6)
Slope formula:
m=(y2-y1)/(x2-x1)
m=(6-4)/(5-0)
m= 2/5
y - y1 = m(x - x1)
y - 4 = 2/5(x - 0)
y - 4 = 2/5x
y = 2/5x + 4
Answer:
The volume for the sphere is 904.78
Answer: the due date would be 92 weeks
Step-by-step explanation:
Since the time required to complete a project is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = number of weeks.
µ = mean
σ = standard deviation
From the information given,
µ = 80 weeks
σ = 10 weeks
If a construction company bidding on this contract wishes to be 90 percent sure of finishing by the due date, the z score corresponding to 90%(90/100 = 0.9) is 1.29
Therefore,
1.29 = (x - 80)/10
x - 80 = 1.2 × 10
x - 80 = 12
x = 80 + 12 = 92
Answer:
James is expected to earn $562.5 at the end of the year as Interest.
Step-by-step explanation:
Here, the amount deposited = Principal = $12,500
Rate of Interest = R = 4.5%
Time = T = 1 year
Now, to find the interest at the end of the year:
or, S I = 
or, S I = $562.5
Hence, James is expected to earn $562.5 at the end of the year as Interest.
Answer:
90km² only if it is parallelogram
Step-by-step explanation:
base = 9km
height=10km
area of parallelogram = b x h
=9km x 10km
=90km²
