Answer:

35 degrees.

Step-by-step explanation:

Since that the line that the exterior 100 degree angle is on is a straight line (which is 180 degrees) we can clearly see the supplementary angle is 180-100 which is 80. A triangle's interior angles add up to 180 degrees which means the missing angle is 180-80-6535 degrees.

Answer:

m angle FED is 35 degrees

Step-by-step explanation:

line DE is bisecting RF.

linear lines have a 180 degree angle.

you are given that m angle RDE is 100, meaning you can subtract 180-100 to find angle FDE.

angle FDE is 80 degrees.

in EVERY triangle, all of the angles always add up to 180 degrees. Knowing this, you can subtract 80 and 65 from 180 to find the missing angle.

180 - 80 - 65 = 35

m angle FED is 35 degrees

The least square regression equation for the information provided is y = 9.72x - 40.776

<u>The general equation of a regression model can be expressed thus</u>:

  • y = bx + c

  • Slope, b = r(Sy/Sx)

Calculating slope, b :

  • b = 0.81(177.6 / 14.8) = 9.72

<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :

696 = 9.72(75.8) + c

696 = 736.776 + c

c = 696 - 736.776

c = - 40.776

Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

Let Upper A equals left bracket Start 2 By 2 Matrix 1st Row 1st Column negative 2 2nd Column 4 2nd Row 1st Column 1 2nd Column 3
Anastaziya [24]

Answer:

See explanation

Step-by-step explanation:

Given:

A=\left[\begin{array}{cc}-2&4\\1&3\end{array}\right]

B=\left[\begin{array}{cc}-2&1\\3&7\end{array}\right]

A. Find AB:

AB=\left[\begin{array}{cc}-2&4\\1&3\end{array}\right]\cdot \left[\begin{array}{cc}-2&1\\3&7\end{array}\right]=\left[\begin{array}{cc}-2\cdot (-2)+4\cdot 3&-2\cdot 1+4\cdot 7\\1\cdot (-2)+3\cdot 3&1\cdot 1+3\cdot 7\end{array}\right]=\left[\begin{array}{cc}16&26\\7&22\end{array}\right]

B. Find BA:

BA=\left[\begin{array}{cc}-2&1\\3&7\end{array}\right]\cdot \left[\begin{array}{cc}-2&4\\1&3\end{array}\right]=\left[\begin{array}{cc}-2\cdot (-2)+1\cdot 1&-2\cdot 4+1\cdot 3\\3\cdot (-2)+7\cdot 1&3\cdot 4+7\cdot 3\end{array}\right]=\left[\begin{array}{cc}5&-5\\1&33\end{array}\right]

C. Answers are not the same

D. Matrices multiplication is not commutastive in general, so

AB\neq BA

BabaBlast [244]

Answer:

The answer is 2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

2/ 3(x)=4/9

Step 1: Multiply both sides by 3/2.

( 3/2)*(2/3*x)=(3/2)*(4/9)

so this means the  answer is 2/3
