<h2>Answer:</h2><h2></h2>

<em> In this context, the missing height measures 7 units</em>

<h2>Explanation:</h2><h2></h2>

The diagram for this problem is shown below. We know that a parallelogram is a quadrilateral where both pairs of opposite sides are parallel. The area (A) for any parallelogram is defined as:

A=B\times H \\ \\ \\ Where: \\ \\ B:Base \ of \ the \ parallelogram \\ \\ H:height \ of \ the \ parallelogram

From the figure, we know:

B=3units

And the statements tells us that the area is:

A=21units^2

So, substituting in our equation for the are:

21=3H \\ \\ \\ Isolating \ H: \\ \\ H=\frac{21}{3} \\ \\ \boxed{H=7units}

<em>So in this context, the missing height measures 7 units</em>

The lengths of plate glass parts are measured to the nearest tenth of a millimeter. The lengths are uniformly distributed with v
yarga [219]

Answer:     \text{Mean length}=590.5\ mm\\\\\text{Variance of the lengths}=0.03\ mm

Step-by-step explanation:

The mean and variance of a continuous uniform distribution function with parameters m and n is given by :-

\text{Mean=}\dfrac{m+n}{2}\\\\\text{Variance}=\dfrac{(n-m)^2}{12}

Given : m=590.2\ \ \ n=590.80

\text{Then, Mean=}\dfrac{590.2+590.8}{2}=590.5\ mm\\\\\text{Variance}=\dfrac{(590.8-590.2)^2}{12}=0.03\ mm

Let's solve ~

\qquad \sf  \dashrightarrow \: 10x + 30 = 90

[ according to given figure ]

\qquad \sf  \dashrightarrow \: 10x = 90 - 30

\qquad \sf  \dashrightarrow \: 10x = 60

\qquad \sf  \dashrightarrow \: x = 60 \div 10

\qquad \sf  \dashrightarrow \: x = 6 \degree

Correct choice is D

The number of freshman at George Washington high school is 60 greater than the number of sophomores. If there are 1250 students
solmaris [256]

Answer:

Hence total number freshman presented are 655.

The system is relative system as there is correlation between freshman and

sophomores<em>.</em><em>( as freshman are 60 more than the Sophomores)</em>

Step-by-step explanation:

Given:

1250 total students of sophomores and freshman.

To Find:

freshman count and its type of system used.

Solution:

We have that ,

consider x be the no.of freshman and y be the sophomores

So by given condition,

x+y=1250        ,..............................Equation(1)

And other one,

x=60+y

Use above value in equation (1) we get ,

60+y+y=1250

2y=1250-60

y=595

Now number of freshman ,

x+y=1250

x=1250-595

x=655

Hence total number freshman presented are 655.

The system represent the relative proportion system.The break even and total value should include all students in university .

Relative means in relationship with one another .

As there are 60 more number of freshman than the sophomores.
