Find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −4, 9) and

Lorico [155]

Answer: x = -4, y = 0.5, z = 5 +t

Hi!

The line L whose direction is parallel to vector V a passes through point A

is parametrized

$P_L = Vt + A$

Where t, is a real number, and $P_L$ is a any point on line L.

In this case the direction is that of the z-axis , so V = (0, 0, 1)

A is the midpoint between points B = (0, -4, 9) and C=(-8, 5, 1)

The midpoint is A = (B + C)/2 = (-4, 0.5, 5)

Then the line is:

$P_L = (0,0,1) t + (-4, 0.5, 5)$

The equations for each coordinate are:

$x = -4\\y = 0.5\\z = 5 + t$

Assume that the weights of quarters are normally distributed with a mean of 5.67 g and a standard deviation of 0.07 g. If a vend

Black_prince [1.1K]

Answer:

0.98046

Step-by-step explanation:

Given:

μ = 5.67

σ = 0.07

Here we are required to find

P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by

So 5.48 we have z = -2.714 and 5.82 we have z = 2.143

Therefore we have the area of interest on the normal distribution chart given by :

P( -2,714 < z < 2.143)

= 1 - P(Z<-2.714) + P(Z > 2.143)

= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))

= 1 - 0.00336 + 1 - 0.98382

= 1 - 0.01954 = 0.98046

Find the area and perimeter

mihalych1998 [28]

Answer:

Area=2232 square ft

Perimeter=206 ft

Step-by-step explanation:

given

the diagram is a rectangle

length=72 ft

width=31 ft

we know that

formula of the area of rectangle= length × width

Area=72×31 square ft

Area=2232 square ft

Now calculate the perimeter

perimeter of rectangle=2(length+width)

perimeter=2(72+31)

perimeter=2(103)

perimeter=206 ft
