Natasha2012 [34]2 years ago
5 0
The answer is 0.50.

P(4<=X<=8)=P(x=4)+ P(x=5)+ P(x=6)+ P(x=7)+ P(x=8)= 0.05+ 0.15+0.15+0.15 +0 = 0.50

Notice that in 8 the line touches the x axis so it’s corresponding probability is 0.

Help please! Identify an equation in point slope form for the line perpendicular to Y =-4x + 8 that passes through (-2, 7)
777dan777 [17]

Answer:

D. y-7=\frac{1}{4}(x+2)

Step-by-step explanation:

The point-slope form of a line is given by:

y-y_1=m(x-x_1)

The line given to us has equation; y=-4x+8.

The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.

Our slope of interest is therefore; m=\frac{1}{4}

Since the point goes through (-2,7), we have x_1=-2,y_1=7.

We plug in the slope and the point into the point-slope formula to obain;

y-7=\frac{1}{4}(x--2)

The required equation is:

y-7=\frac{1}{4}(x+2)

Solve the following 2 equation.<br>I will Make Brainliest​
Levart [38]

Answer:

d.  x = 10

e. x=\sqrt[3]{\dfrac{15}{4}}

Step-by-step explanation:

I've typed up my workings in MS Word and attached them (as it's very difficult to type this in the Brainly equation editor).

I've used the product, quotient and power log laws.

Product:     log_a(x)+log_a(y)=log_a(xy)

Quotient:    log_a(x)-log_a(y)=log_a(\dfrac{x}{y})

Power:    p\log_a(x)=log_a(x^p)

Solve by factoring c^2=5c
muminat
Hey there!

c² = 5c

Subtract 5c from both sides:

c² - 5c  = 5c - 5c

Simplify :

c² - 5c = 0

c = 5 , c = 0
