Answer:

So the possible answer would be 59%

Step-by-step explanation:

A study estimated that 64% of the residents of a town (with an error range of +-12 percentage points at 95% confidence)  

In this question study gives a range 64 + or -12 it means they are not sure about answer but they estimated answer choice between 52 to 76

(64 - 12= 52 to 64 + 12 = 76).

I would figure out the lowest estimate and the highest estimate. and the answer would be between the two numbers.

In the choices there is only one number between 52 and 76. So the possible answer would be 59%.

pychu [463]

Determine the slope of the line that contains the points A(0, 2) and B(7,3). *
IgorC [24]

<h3><u>Given</u><u> </u><u>points</u><u>:</u><u>-</u></h3>
  • A (0,2)
  • B (7,3)

We know that

{\boxed{\sf Slope_{(m)}=\dfrac {y_2-y_1}{x_2-x_1}}}

  • Substitute the values

\qquad\quad {:}\longrightarrow\tt m=\dfrac {3-2}{7-0}

\qquad\quad {:}\longrightarrow\tt m=\dfrac {1}{7}

\therefore \sf Slope\:of\:the\:line\:is\:\dfrac {1}{7}

How many 3/4 goes into 9/2
gavmur [86]

Answer: 6

Step-by-step explanation: First, let's find the least common denominator between the 2 fractions, which is 4. Now let's multiply 9/2 by 2 to get the denominator of 4. Once you multiply the numerator and denominator by 2 you would get 18/4. So now the problem turns into how many 3/4 goes into 18/4. We know that 3/4 x 6 = 18/4. So the final answer is 6.
