It goes like this 1/2, 1/4, 1/8. But if your asking about what fraction didn’t get affected than that just zero because the original peace was cut in half.

If that’s not what you mean can you please elaborate to me!

Suppose a horticulturist measures the aboveground height growth rate of four different ornamental shrub species grown in a green

Complete Question

The complete question is shown on the first uploaded image

Answer:

The decision is to <u>reject</u> the <u> null hypothesis</u> at a significant level of <u>significance </u> \alpha  = 0.05 There is <u>sufficient </u> evidence to conclude that <u>at least one of the population mean</u>  is <u>different from</u>  <u>at least of the population</u>  

Step-by-step explanation:

From the question we are told that the claim is

     The mean growth rates of all four species are equal.

The  null hypothesis is  

             H_o  :  \mu _1 =  \mu_2 = \mu_3  =  \mu_4

Th alternative hypothesis is    

             H_a: at \ least \ one \ of \  the \  means \ is \not\ equal

From question the p-value is p-value  =  0.015

  And since the p-value <  \alpha so the null hypothesis will be rejected

So  

   The decision is to <u>reject</u> the <u> null hypothesis</u> at a significant level of <u>significance </u> \alpha  = 0.05 There is <u>sufficient </u> evidence to conclude that <u>at least one of the population mean</u>  is <u>different from</u>  <u>at least of the population</u>

What is the equation in slope intercept form of the line that contains the point (8, -2) and has a y-intercept of -4?
Alecsey [184]
Y=mx+b,slop intercept form
we need to find the slope.we nned to point
(-8,2) is given you can get the other by understanding the defintion of y-intercept (0,-4)
m = slope =  \frac{ 2  - ( -  4)}{ - 8 - 0}  =  \frac{6}{ - 8}
m=-6/8,b=y-intercept=-4
y =  \frac{ - 6}{8} x  + ( - 4)

Solve for x in the equation
FinnZ [79.3K]
X^2+4x-4=8
x^2+4x-4-8=0
x^2+4x-12=0
x^2+6x-2x-12=0
x(x+6)-2(x+6)=0
x+6=0   x-2=0
x=-6  x=2

Find the circumference of a circle if the area is 300 square centimeters.
Blababa [14]
The answer is:  [C]:  61.38 cm  .
_______________________________________________

Note:  A = \pi *r²

300 = (3.14) * r² ;
______________________
Divide each side by "3.14" ;

r² = 300/3.14 ; 

r² =  95.5414012738853503 ;

√r² = √(95.5414012738853503) ;

r = 9.7745281867661188048

Circumference, "C" = \pi * d ;  (d = diameter = 2*r);
 
C = 2*\pi*r ;

C = 2*(3.14)*(9.7745281867661188048)

C = 61.384037012891226094144 ; which rounds to answer choice: 
                                                             [C]:  61.38 cm  .
