What is the equation of this line?

Mathematics
1 answer:
jolli1 [7]3 years ago
4 0
Slope-point form:
y=mx b

We need two points to work out the slope; for example in this line we have:
(0,-2)
(4,0)
m=(y₂-y₁)/(x₂-x₁)

m=(0+2)/(4-0)=2/4=1/2

In this line the y-intercept (b)=-2

The equation of the line will be:   y=1/2 x-2

Answer: y=1/2 x-2

Based on a poll, 40% of adults believe in reincarnation. Assume that 8 adults are randomly selected, and find the indicated prob
Veronika [31]

Answer:

The probability under the given conditions is found:

P(7) = 0.079

Step-by-step explanation:

Let x be the number of adults who believe in reincarnation.

Adults randomly selected = 8

percentage of adult believe in reincarnation = 40% = 0.4

x follows binomial distribution:

P(x) =  \left(\begin{array}{ccc}n\\x\end{array}\right) (p)^x(1-p)^{n-x}

where

n= total people random people selected = 8,

x = selected for the part = 7,

p = probability given = 0.4

P(7) = \left(\begin{array}{ccc}8\\7\end{array}\right) (0.4)^7(1-0.4)^{8-7}

P(7)= (8)(0.0164)(0.6)

P(7) = 0.07872

Rounding off to 3 decimal positions

P(7) = 0.079
