ExtremeBDS [4]3 years ago
7 0

Answer: False

Nothing is 100% certain no matter how sure it seems. This is especially true with statistics. There's always going to be some amount of error. The goal is to minimize the error as much as possible in the best cost-effective manner.

1. Determine the following set of adjustments to the equation then draw the graph !!
suter [353]

Answer:

y = -1 and u = 3.333

Step-by-step explanation:

The given equations are :

3u + y = 9 ...(1)

3u-5y = 15 ...(2)

Subtract equation (2) from (1).

3u + y-( 3u-5y)= 9 -15

y+5y = -6

6y = -6

y = -1

Put the value of y in equation (1).

3u + (-1) = 9

3u-1 = 9

3u = 10

u = 10/3

u = 3.333

The attached figure shows the graph for the above equations.

For what values of x and y must ABCD be a parallelogram?
n200080 [17]
<h2>x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}</h2>

Step-by-step explanation:

We know that vertically opposite angles of a parallelogram are equal .

\angle ABC =\angle ADC\ and \ \angle BAD = \angle DAC

⇒3x^{\circ}=(4x-21)^{\circ} \ and \ 3y^{\circ}=(y+78)^{\circ}

⇒3x^{\circ}-4x^{\circ}=-21^{\circ} \ and \ 3y^{\circ}-y^{\circ}=78^{\circ}

⇒-x^{\circ}=-21^{\circ} \ and \ 2y^{\circ}=78^{\circ}

⇒x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}
