Answer:

\Longrightarrow: \boxed{\sf{2\sqrt{13}}}

Step-by-step explanation:

<u>Question</u>:

  • Find the distance between (-4,-3) (2,1)

<u>To find:</u>

  • The distance between (-4,-3) (2,1).

Use the distance formula.

<u>Distance formula:</u>

\Longrightarrow: \sf{\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}}

\sf{y_2=1}\\\\\sf{y_1=(-3)}\\\\\sf{x_2=2}\\\\\sf{x_1=(-4)}

\Longrightarrow: \sf{\sqrt{\left(2-\left(-4\right)\right)^2+\left(1-\left(-3\right)\right)^2}

Solve.

\Longrightarrow: \boxed{\sf{2\sqrt{13}}}

  • <u>Therefore, the final answer is 2√13.</u>

I hope this helps, let me know if you have any questions.

Answer:

2\sqrt{13}

Step-by-step explanation:

d=\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}

d=\sqrt{(2--4)^{2}+ (1--3)^{2}}\\\\d=\sqrt{(6)^{2}+ (4)^{2}}\\\\d=\sqrt{36+16}\\\\d=\sqrt{52}\\\\d=2\sqrt{13}

Find the measure of b+d. A. 74 B. 90 C. 32 D. 58
Sav [38]

Answer:

B. 90°

Step-by-step explanation:

Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

(b + d) + (32° + 58°) = 180°

b + d + 90° = 180°

b + d = 180° - 90°

b + d = 90°

Which of the following is an inequality sentence?
ziro4ka [17]

Answer:

C. x

Step-by-step explanation:

  • Option A [x+5=20]tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
  • Option B[x=5] tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
  • Option C[x tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
  • Option D[x+5] is an expression; It can't be called an equation or an inequality unless we relate it with another expression.

A recent study of 26 city residents showed that the time they had lived at their present address has a mean of 10.3 years with t
svetlana [45]

Answer:

The 95% confidence interval is  9.15<  \mu < 11.45

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  26

      The mean is  \= x =  10.3

       The standard deviation is  s =  3

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

=>   E =  1.96 *  \frac{3}{\sqrt{26} }

=>   E = 1.1532

Generally 95% confidence interval is mathematically represented as  

      \= x -E <  \mu <  \=x  +E

=>   10.3  -1.1532 <  \mu < 10.3  +  1.1532

=>    9.15<  \mu < 11.45
