Which of the following indicates the subtraction property of equality when solving the equation 4(x + 9) + 5 = 3x − 8? Question
jeka94

Answer: 4(x + 9) = 3x − 8 − 5

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

4(x + 9) + 5 = 3x − 8

The subtraction property of equality states that if we subtract the same number from both sides of the equation, the equality remains.

So, if we subtract 5 from both sides:

4(x + 9) + 5-5 = 3x − 8 -5

4(x + 9) = 3x − 8 − 5  

Feel free to ask for more if needed or if you did not understand something.

a. Show the sampling distribution of p, the proportion of groceries thrown out by your sample respondents.b. What is the probabi
Anika [276]

Answer:

The corresponding p - value will be  is < 0.00001 which is less than 0.05

Step-by-step explanation:

Suppose p= 0.12 and n= 540 then the standard deviation can be taken out as √p(1-p)/n= √0.12(1-0.12)/540= 0.014

For the probability that the survey will provide a sample proportion within 6.03 of the population proportion

we will find the z statistic

z= p^-p/√p(1-p)/n

But √p(1-p)/n= 0.014 and p^-p= 6.03

Putting the values

z= 6.03/0.014= 430.71

The corresponding p - value will be  is < 0.00001 which is less than 0.05

Please help!!!!!!!!!! !!
mestny [16]

Answer:

The ~length~ is ~9.6~ units ✔︎

༄❁༄❁༄❁༄❁༄

a=8\\b=2\\c=?\\d=?\\e=5

Using~ Pythagorean ~theorem:

c^2=a^2+b^2

c^2=(8)^2+(2)^2

\sqrt{c^2} =\sqrt{68}

c=\sqrt{68} ~or~2\sqrt{17}

»»---------------------►

d^2=c^2+e^2

d^2=(2\sqrt{17})^2+(5)^2

d^2=68+25

\sqrt{d^2} =\sqrt{93}

d=\sqrt{93} ~or~9.6

So, your~ answer ~is ~9.6
