Then it would be : 1/4 * 128 = 32

So, original price will be 128 - 32 = 96

128,00 is 3/4 of the first prize. 128:3×4=170,67

The mean is the average . the sum of number over the number of observation

x1=525

x2=487

s.d1=59.42

s.d2=51.74

n1=16

n2=12\alpha =0.05

Determine the hypothesis

H_{0}: u1≤u2

H_{a} :u1>u2

find the degree of freedom(\frac{s1^2}{n1} +\frac{s2^2}{n2} )^2/(\frac{s1^2}{n1} )^2/n1-1+(s2^2/n2)^2/n2-1\\\\(\frac{59.42^2}{16} +\frac{51.7476^2}{12} )^2/(\frac{59.42^2}{16} )^2/16-1+(51.74^2/12)^2/12-1

p-value is the probability of obtaining the value of the test statistics. In the column of t-value in the row df=25

0.025<P<0.05

if the P value is actually less than or the same as the significant level, then the null hypothesis is rejected

P<0.05   rejected H

Answer:

0.001189 x 10^7

Step-by-step explanation:

4.1 x 10^7 gallons of water

2,900 gallons of water = 2.9 x 10^3

Balance the 10th power with the first one.

2,900 = 0.00029 x 10^7

Multiply only the decimal number...

4.1 x 0.00029 = 0.001189

The answer is...

0.001189 x 10^7

Rachel is drawing a square. She draws a circle with a compass setting of r units. Which of the following is the next thing Rache
natka813 [3]

Answer:

<em><u /></em>

  • <em><u>A. Draw a diameter of the circle. </u></em>

Explanation:

To<em> draw a square</em> you can <em>draw a circle</em> with a <em>compass</em> and then construct the inscribed square.

You can construct an inscribed square with a compass and a straightedge.

The <u>first step</u> is to draw the circle.

The <u>next</u> step is to <em>draw a diameter</em> (any line that passes through the center of the circle, which you marked when drew the circle). Hence, this is the correct answer to the queston, and it is described by the choice A.

After that, you will be able to draw the perpendicular bisector of the diameter. The two diameters drawn will mark four equidistant points on the circle which will be the four vertices of your square.

Finally, you just must join the adjacent vertices with the straightedge.
