Answer:

a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.

b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.

What is the volume of a rectangular prism with the dimensions: base 2 3 8 cm, height 1 1 3 cm, and length 3 3 4 cm? A) 11 7 8 cm

shusha [124]

Answer:

The volume of the given prism is $11\frac{7}{8}$ cubic cm.

Step-by-step explanation:

Here, the dimensions of the given Prism is

Base = $2\frac{3}{8}$ cm

Height = $1\frac{1}{3}$ cm

Length = $3\frac{3}{4}$ cm

Now. solving the given mixed fractions, we get

$2\frac{3}{8} = 2 + \frac{3}{8} = 2 + 0.375 = 2.375$

$1\frac{1}{3}= 1 + \frac{1}{3} = 1 + 0.333 = 1.33$

$3\frac{3}{4} = 3 + \frac{3}{4} = 3 + 0.75 = 3.75$

Now, the given dimensions of the prism are :

B = 2.375 cm, H = 1.33 cm and L = 3. 75 cm

The VOLUME OF THE PRISM = LENGTH x BASE x HEIGHT

= 2.375 cm x 1.33 cm x 3. 75 cm

= 11. 8453 cubic cm

Now, $11. 8453 = 11 + 0.845 = 11 + \frac{845}{1000} = 11 + \frac{7}{8} = 11\frac{7}{8}$

Hence, the volume of the given prism is $11\frac{7}{8}$ cubic cm.

Find an equation of the plane through the point(1, 5,-1) and perpendicular to the vector (1, 5, 1). Do this problem in the stand

Vladimir79 [104]

Answer:

<h2>x+5y+z = 25</h2>

Step-by-step explanation:

Given a plane passing through the point(1, 5,-1) and perpendicular to the vector (1, 5, 1), the equation of the plane can be expressed generally as;

a(x-x₀)+b(y-y₀)+c(z-z₀) = 0 where (x₀, y₀, z₀) is the point on the plane and (a, b,c) is the normal vector perpendicular to the plane i.e (1,5,1)

Given the point P (1, 5, -1) and the normal vector n(1, 5, 1)

x₀ = 1, y₀ =5, z₀ = -1, a = 1, b = 5 and c = 1

Substituting this point in the formula we will have;

a(x-x₀)+b(y-y₀)+c(z-z₀) = 0

1(x-1)+5(y-5)+1(z-(-1)) = 0

(x-1)+5(y-5)+(z+1) = 0

x-1+5y-25+z+1 = 0

x+5y+z-1-25+1 = 0

x+5y+z-25 = 0

x+5y+z = 25

The final expression gives the equation of the plane.
