Masja [62]

Answer:

The mean is  \mu  = 2.1

Step-by-step explanation:

The mean number of employees calling sick per day can  be mathematically represented as

       \mu  = 0* 0.05 + 1 * 0.40 + 2 * 0.3 + 3 * 0.3 + 4*0.05

      \mu  = 2.1

Researchers have found that after 25 years of age the average size of the pupil in a
laila [671]

Answer:

At 25 = 6.8612mm

At 50 years = 5.422mm

Step-by-step explanation:

Equation,

d = 2.115Logₑa + 13.669

d = diameter of the pupil

a = number of years

Note : Logₑa = In a (check logarithmic rule)

d = 2.115Ina + 13.669

1. At 25 years,

d = -2.115In25 + 13.669

d = -2.115 × 3.2188 + 13.669

d = -6.807762 + 13.669

d = 6.8612mm

At 25 years, the pupil shrinks by 6.86mm

2. At 50 years,

d = -2.1158In50 + 13.669

d = -2.1158 * 3.912 + 13.669

d = -8.2770 + 13.699

d = 5.422mm

At 50 years, the pupil shirks by 5.422mm

To save this question, I had to plug in the values into the equation.

Solving for Logₑa might be difficult, so instead I used Inx which is the same thing. Afterwards, i substituted in the values and solve the equation for each years.

What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)? (5 points)
Margaret [11]

Answer:

A) y=2(x+2)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-0)/(2-(-2))

m=8/(2+2)

m=8/4

m=2

y-y1=m(x-x1)

y-0=2(x-(-2))

y=2(x+2)

y=2x+4
