Answer:

Distance between mall and library is 6.32 miles.

Step-by-step explanation:

Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).

Since, distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By this formula,

Distance between (2, 4) and (8, 4) will be,

Distance = $\sqrt{(8-2)^2+(2-4)^2}$

= $\sqrt{36+4}$

= $\sqrt{40}$

= 6.32 miles

The sum of 3 consecutive even numbers is 132<br><br>pleaase help!!!

agasfer [191]

Answer:

42,44,46

Step-by-step explanation:

we first divide the 132 by the 3 which gives 44

since the numbers involved are even numbers and we know even numbers are numbers divisible by 2 we subtract 2 from the 44 and also add 2 to the 44 the get the rest of the two numbers which is from the above explanation

(44-2),44,(44+2)

42,44,46

we can check whether the above numbers are correct by adding to see whether we get 132

42+44+46=132 which are consecutive even numbers

onsider two populations for which μ1 = 38, σ1 = 2, μ2 = 23, and σ2 = 4. Suppose that two independent random samples of sizes n1

levacccp [35]

Answer:

Center = 15

Spread = 0.599

Shape = Normal

Step-by-step explanation:

The provided information is:

$\mu_1=38 \ \ \ \ \ \ \ \ \mu_2 = 23\\\sigma_1 =2 \ \ \ \ \ \ \ \ \ \sigma_2=4\\n_1=45 \ \ \ \ \ \ \ \ n_2 =59$

Thus the center(mean) of the distribution is:

$\begin{aligned}Mean &= \mu_1-\mu_2\\&=38-23\\&=15\end{aligned}$

The spread (standard deviation) of the distribution is:

$\begin{aligned}\textrm{Standard deviation}&=\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}\\&=\sqrt{\frac{4}{45}+\frac{16}{59}}\\&=0.599\end{aligned}$

The shape of the distribution is also normally distributed.
