Answer:

-The probability of choosing a meat dish is equal to the probability of choosing a pasta dish or a soup(P(meat)\neq P(pasta)+P(soup))

Step-by-step explanation:

Given that the number of events is 25 and 13 are meat dishes, 8 are pasta dishes, and 4 are soups.

-Probability is defined as the number of successful event divide by the total number of events.

#find probability of each event:

P(meat)=\frac{13}{25}=0.52\\\\P(pasta)=\frac{8}{25}=0.32\\\\P(soup)=\frac{4}{25}=0.16

P(meat)\neq P(pasta)\neq P(soup)

Hence, the FALSE choice is:The probability of choosing a meat dish is equal to the probability of choosing a pasta dish or a soup.

(x-3y+ 3z=-4<br><br> 2x+3y-z =15<br><br> (4x-3y- z=19<br><br> - What is the solution to the system?
lesya [120]

Answer:

x=5,y=1 and z=-2

Step-by-step explanation:

We are given that system of equation

x-3y+3z=-4 (I equation)

2x+3y-z=15  (II equation )

4x-3y-z=19  (III equation )

Equation II multiply by 3 then add  with equation I

Then, we get

7x+6y=41 ....(Equation IV)

Subtract equation II from equation III then we get

2x-6y=4  (equation V)

Adding equation IV and equation V then, we get

9x=45

x=5

Substitute x=5 in equation V then, we get

2(5)-6y=4

10-6y=4

6y=10-4=6

y=1

Substitute x=5 and y=1 in equation then, we get

5-3(1)+3z=-4

2+3z=-4

3z=-4-2=-6

z=\frac{-6}{3}=-2

Hence, the solution for the given system of equation is given by

x=5,y=1 and z=-2

Which is the additive inverse of the complex number -8+3i?
lawyer [7]
The additive inverse of a complex z is a complex number -z, so that

\mathsf{z+(-z)=-z+z=0+0i=0}


Finding -z:

\mathsf{z=-8+3i}\\\\\\ \mathsf{z+(-z)=0+0i}\\\\\ \mathsf{-8+3i+(-z)=0+0i}\\\\ \mathsf{-z=0+0i+8-3i}\\\\ \mathsf{-z=(0+8)+(0i-3i)}\\\\ \boxed{\begin{array}{c}\mathsf{-z=8-3i} \end{array}}\qquad\checkmark
