leonid [27]

Answer:

No.

Step-by-step explanation:

Based on the​ sample, "52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus​3%." The margin of error was based on a​ 95% confidence level.

Then 95% Confidence Interval is between 49% and 55%. Since confidence interval also includes non-majority proportions, the assumption that "95% confidence, Robert Smith will win the election" cannot be made.

8x+5y=24<br><br> y=-4x<br><br><br> Solve for y and x
Cloud [144]

Answer:

x= -2           and y= 8

Step-by-step explanation:

8x+5y=24-------A

y=-4x---------B

Putting the value of y from B in A

8x+5(-4x)=24

8x +(-20x)= 24

8x-20x=24

-12x=24

x= -24/12

x=-2--------C   y =-4(-2)=8

Got a fairly simple looking system of equations, 2k+4y=20, and 3x+6y=30 Don't understand how to prove what values of k provide -
Leya [2.2K]

Answer:

2kx+4y=20 ⇒ kx+2y=10

3x+6y=30 ⇒ x+2y= 10

k is the coefficient of x, so it is the slope of the line

  • when k=1, both equations will be same, then there are many solutions
  • when k=0 there is one solution
  • when k is anything different, then the lines will be parallel, so no solutions

A certain slot machine has three identical independent wheels, each with 13 symbols as follows: 1 bar, 2 lemons, 2 bells, 2 plum
kari74 [83]

Answer:

Step-by-step explanation:

Given

there are 13 symbols in slot machines i.e. 1 bar , 2 lemons , 2 bells ,2 plums ,3 cherries , 3 oranges

there are Total of 3 machines

Probability of getting bar in machine is \frac{1}{13}

Probability of getting 3 bar on 3 machine=\frac{1}{13} \times\frac{1}{13}\times \frac{1}{13}=\frac{1}{2197}=0.0004

Probability of getting an orange=\frac{3}{13}

Probability of getting 3 oranges  on 3 machine=\frac{3}{13} \times\frac{3}{13}\times \frac{3}{13}=\frac{27}{2197}=0.0122

Probability of getting a Plum=\frac{2}{13}

Probability of getting 3 Plums  on 3 machine=\frac{2}{13} \times\frac{2}{13}\times \frac{2}{13}=\frac{8}{2197}=0.0036
