Answer:

(10111)2 = (23)10

Step by step solution

Step 1: Write down the binary number:

10111

Step 2: Multiply each digit of the binary number by the corresponding power of two:

1x24 + 0x23 + 1x22 + 1x21 + 1x20

Step 3: Solve the powers:

1x16 + 0x8 + 1x4 + 1x2 + 1x1 = 16 + 0 + 4 + 2 + 1

Step 4: Add up the numbers written above:

16 + 0 + 4 + 2 + 1 = 23.

So, 23 is the decimal equivalent of the binary number 10111.

antiseptic1488 [7]

Answer:

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

The Rank for  Group1  is 115.5 and Group 2 is 55.5.

Conclusion is that Worker productivity is higher with automatic dispensers.

Step-by-step explanation:

The null and alternative hypotheses are

H0: Group1 ≤ Group2   against the claim

Ha: Group1 > Group2

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

Calculations:

                                        Group1               Group2

Sample Mean   x `       139.22               114.67

Sample size n                   9                         9

Sample SD                     18.21                  11.937

Rank                               115.5                       55.5

U                                      10.5                          70.5

<u><em>The Rank for  Group1  is 115.5 and Group 2 is 55.5.</em></u>

<u><em></em></u>

<em><u>1. H0 hypothesis</u></em>

As p-value < alpha  and Z lies in the critical region, H0 is rejected.

The randomly selected value of Group1's population is considered have greater productivity  than the randomly selected value of Group2's population.

<em><u>2. P-value</u></em>

The p-value equals 0.0046.

<em><u>3. Test statistics</u></em>

<em><u>Z= u-μ+c/σ</u></em>

The critical region for one tailed test for z at 0.01 significance level is

z > 2.33.

The test statistic Z equals 2.6063, which lies in the critical region of acceptance z> 2.326

<u><em>4. Conclusion</em></u>

As the calculated test statistic lies in the critical region H0 is rejected and it is concluded that

<em><u>Worker productivity is higher with automatic dispensers. </u></em>

A triangular prism has a Surface Area of 48.735 km2. The base of the prism is a triangle with a height of 3 and an unknown base.
xeze [42]
The surface area of the prism is equal to the summed up area of the faces of the triangular prism.

The bases of the prism would be triangles with an unknown base, b, and height of 3. The area of the base is calculated through the equation,
          A = bh/2
where b is base and h is height. Substituting the values,
       A = b(3)/2

Since there are two bases, the contribution of the triangles for the surface area is,
   2A = 3b

Next we calculate for the area of the triangle sides with length equal to b (same as the base of the triangle). 
   Area = b(12 km)
There are 3 sides such that the total area becomes,
   Area = 36b

Hence, the surface area is,
    48.735 km² = 3b + (36b)

The value of b from the equation is 1.25 km

<em>ANSWER: 1.25 km</em>
