Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second
stiks02 [169]


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5

G a survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related
Naily [24]

Answer:

The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.

Step-by-step explanation:

The data provided is:

                                                   Opinion    

Front Footage   For       Undecided Against    Total

Under 45 feet    12                4              4              20

  45-120 feet           35                5             30      70

Over 120 feet     3                2              5              10

       Total           50                11             39    100

The formula to compute the expected frequency is:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

E(5)=\frac{10\times 39}{100}=\frac{39}{10}=3.9

Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
