y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

<h3>What is Slope of Line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

In the perpendicular lines the product of slopes will be -1

m1m2=-1

y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.

The line is passing through (8,2)

2=-1(8)+b

2=-8+b

2+8=b

10=b

Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

Find an equation to show the population of growing bacteria
Oksanka [162]

Answer:

P=1,000(1.4)^t

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

P=a(1+r)^t

where

P is the population

t is the time in years

a is the initial value

r is the rate of change

<u><em>Looking at the table</em></u>

For t=0

The value of P=1,000

so

substitute the value of the ordered pair (0,1,000) in the exponential equation

1,000=a(1+r)^0\\a=1,000

The initial value is a=1,000

substitute

P=1,000(1+r)^t

For t=1

The value of P=1,400

so

substitute the value of the ordered pair (1,1,400) in the exponential equation

1,400=1,000(1+r)^1\\r=1.4-1\\r=0.4\\r=40\%

therefore

The exponential equation is

P=1,000(1.4)^t

A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard de
hjlf

Answer:

The answer is below

Step-by-step explanation:

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%

Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

How do you solve 1 1/2 × ( − 6/15 ) =?
Andreas93 [3]

Answer:

1.5 x -0.4 = -0.6 or -6/10 or -3/5

Step-by-step explanation:

1 1/2= 3/2x(-6/15)

3/2 = 1.5  -6/15 = 0.4

1.5 x -0.4 = -0.6 or -6/10 or -3/5
