In AABC, point D is on AB, and point E is on BC
Serhud [2]

Answer:

AC=\frac{27}{2}

Step-by-step explanation:

We are given a Triangle ABC , and DE││BC , where D and E lies on AB and BC Respectively. As DE││BC , ABC is similar to BDE. Hence the ratios of the respective sides will be equal . Hence

\frac{BD}{AB}=\frac{DE}{AC} ----------(A)

Given BD=2

BA=BD+AD=2+7=9

DE=3

Putting these values in (A)

\frac{2}{9}=\frac{3}{AC}

AC=  \frac{3 \times 9}{2}

AC=\frac{27}{2}

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 20
Vikentia [17]

Answer:

Random variable: for this case represent the number of complaints in 2007

Population parameter: represent the real proportion of complaints in 2007 p

Hypothesis to verify

We want to check if the true proportion of complaints in 2007 is equal to 0.23, the system of hypothesis are.:  

Null hypothesis:p=0.23  

Alternative hypothesis:p \neq 0.23  

Step-by-step explanation:

Information provided

n=1432 represent the random sample taken

X=321 represent the number of complaints

\hat p=\frac{321}{1432}=0.224 estimated proportion of complaints in 2007

p_o=0.23 is the value to verify

z would represent the statistic

Random variable: for this case represent the number of complaints in 2007

Population parameter: represent the real proportion of complaints in 2007 p

Hypothesis to verify

We want to check if the true proportion of complaints in 2007 is equal to 0.23, the system of hypothesis are.:  

Null hypothesis:p=0.23  

Alternative hypothesis:p \neq 0.23

The vertex of this parabola is at (-4,-1).When the y-value is 0,the x-value is 2.What is the coefficient of the squared term in
densk [106]

Answer:

  1/36

Step-by-step explanation:

When the coefficient is 1, the function has zeros at -3 and -5, one horizontal unit from the vertex. You want to move the zero to (2, 0), which is 6 units from the vertex. To achieve a horizontal stretch by a factor of 6, the value of x in the function must be replaced by x/6. That would make the coefficient of x^2 be (1/6)^2 = 1/36.

The coefficient of the squared term is 1/36.
