C; $30 per hour

Step-by-step explanation:

120/4=30

If you find one of the coordinate points, you can divide y by x to find the answer since it is asking for per hour.

Answer:

$15 per hour

Step-by-step explanation:

If you look ay hour 1 you can see it is just shy of 80 therefore it would be a $15 increase if you look at hour 2 you can see it is between 80 and 100 which would be 90 that would be 60+15+15=90

svet-max [94.6K]

Answer:

The probability of seeing a person wearing black shoes before seeing a person wearing white ones = 60%

Step-by-step explanation:

People watched walking down the street = 100%

People wearing black shoes = 1/2 = 50%

People wearing white shoes = 1/3 = 33.33%

People wearing red shoes = 1/6 = 16.67%

Probability of black shoes to white shoes = percentage of persons wearing black shoes/sum of the percentages of people wearing black and white shoes)

= 50% : 33.33%

= 60% (50%/83.33%)

When expressed in ratio terms, it means that you will see 1.5 (50%/33.33% or 1.5 : 1) persons wearing black shoes before you see a person wearing white shoes.

garri49 [273]

Answer:

A.

This assumption is that the distribution of polyunsaturated fat % of each if these four regimes must be with equal variances as well as uniform.

B.

The null hypothesis

H0: μ1 = μ2 = μ3 = μ4

The alternate hypothesis:

H1: at least 2 means are unequal

C.

First we calculate the grand mean

= 1/54[15(42.9)+17(43.1)+8(43.7)+14(43.9)]

= (643.5 +732.7 + 349.6 + 614.6)/54

= 2340.4/54

= 43.341

Sum of squared treatment

= [15(42.9-43.341)²+17(43.1-43.341)²+8(43.7-43.341)²+14(43.9-43.341)²]

= 9.3104

Mean square of treatment

= SST/I-1

= 9.3104/4-1

= 9.3104/3

= 3.1035

Error sum of squared

= (15-1)*(1.3)² + (17-1)*(1.5)² + (8-1)*(1.2)² + (14-1)*(1.2)²

= 88.46

Error mean square

MSE = 88.46/54-4

= 1.7692

Test statistic

= 3.1035/1.7692

= 1.75

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

-x - 2y = 2

4x - 2y = -8

<u>Step 2: Rewrite Systems</u>

-x - 2y = 2

  1. Multiply both sides by -1:                    x + 2y = -2

<u>Step 3: Redefine Systems</u>

x + 2y = -2

4x - 2y = -8

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine equations:                    5x = -10
  2. Divide 5 on both sides:                x = -2

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define equation:                    4x - 2y = -8
  2. Substitute in <em>x</em>:                       4(-2) - 2y = -8
  3. Multiply:                                  -8 - 2y = -8
  4. Isolate <em>y</em> term:                        -2y = 0
  5. Isolate <em>y</em>:                                 y = 0
