Find the values of sand y <br> VR=y<br> TS=x+11<br> VT=y-3x <br> RS=x+2
Bumek [7]
I'm guessing this is a parallelogram or something, so VR=TS and RS=VT
therefore, y=x+11 and x+2=y-3x
y=x+11 , 2=y-4x
y=x+11 , y=4x+2
then use the process of elimination:
   y=4x+2         then plug in:    y=3+11
-  y=x+11                                 y=14
   0=3x-9                     I think this is how you'd do it, tbh it's just an educated
  3x=9 , x=3                               guess. Btw, sorry if it looks weird

Determine the critical value or values for a one-mean z-test at the 1% significance level if the hypothesis test is right-tailed
kifflom [539]

Answer:

We need to conduct a hypothesis in order to determine if the mean is greater than specified value, the system of hypothesis would be:      

Null hypothesis:\mu \leq \mu_o      

Alternative hypothesis:\mu > \mu_o      

For this case the significance is 1%. So we need to find a critical value in the normal standard distribution who accumulates 0.99 of the area in the left and 0.01 in the right and for this case this critical value is:

z_{crit}= 2.326

Step-by-step explanation:

Notation

\bar X represent the sample mean

\sigma represent the standard deviation for the population      

n= sample size      

\mu_o represent the value that we want to test    

\alpha represent the significance level for the hypothesis test.    

z would represent the statistic (variable of interest)      

State the null and alternative hypotheses.

(2x + 5)(x2 + 5x + 1)
posledela

Answer:

2x^3 + 15x^2 + 27x + 5

Step-by-step explanation:

2x(x^2 + 5x + 1) + 5(x^2 + 5x + 1)

2x^3 + 10x^2 + 2x + 5x^2 + 25x + 5.....then

add the values with the same variables...

2x^3 + (10x^2 + 5x^2) + (2x + 25x) + 5

; 2x^3 + 15x^2 + 27x + 5
