Answer:

  x = 72

Step-by-step explanation:

Multiply by 1500 mL.

  \displaystyle\frac{12\text{ mL}}{250\text{ mL}}=\frac{x\text{ mL}}{1500\text{ mL}}\\\\\frac{12\text{ mL}}{250\text{ mL}}\cdot1500\text{ mL}=\frac{x\text{ mL}}{1500\text{ mL}}\cdot1500\text{ mL}\\\\12\text{ mL}\cdot\frac{1500}{250}=x\text{ mL}\\\\72\text{ mL}=x\text{ mL}\quad\Rightarrow\quad\boxed{x=72}

If you roll a die what is the probability of rolling a 2 or 6?
Vinil7 [7]

Answer:

\frac{2}{6}

Step-by-step explanation:

We have that, a die is rolled once.

As, the total outcomes can be 1, 2, 3, 4, 5, 6.

So, the probability to obtain 2 is \frac{1}{6} and the probability to obtain 6 is \frac{1}{6}.

Thus, the probability of rolling 2 or 6 after rolling a die once will be \frac{1}{6}+\frac{1}{6} i.e. \frac{2}{6}.

Hence, the probability of rolling a 2 or 6 is \frac{2}{6}.

the midpoint of [KL] is (-8, 1). one endpoint is K(-6, 5). find the coordinates of the other endpoint L
ExtremeBDS [4]

the correct question is

The midpoint of kl is m(–8, 1). one endpoint is k(–6, 5). find the coordinates of the other endpoint l.


we know that

the formula of midpoint is

Xm=(x1+x2)/2----> 2*Xm=x1+x2------> x2=2*Xm-x1

Ym=(y1+y2)/2----> 2*Ym=y1+y2------> y2=2*Ym-y1


let

(x1,y1)-------> (–6, 5).

(Xm,Ym)-----> (-8,1)


find (x2,y2)

x2=2*Xm-x1-----> 2*(-8)-(-6)----> -10

 y2=2*Ym-y1----> 2*(1)-5-----> -3


the point l is (-10,-3)

A building manager installs sensors to see how often people turn off the lights when they leave the room. After a month the mana
vichka [17]

Answer:

D. 68%

Step-by-step explanation:

The following statistics are given;

sample mean = 47%

s = 5% ; the sample standard deviation

n = 625 ; the sample size

The confidence interval for a population mean is given as;

sample mean ± z-score*\frac{s}{\sqrt{n} }

Substituting the above values we have;

47 ± z-score*\frac{5}{\sqrt{625} }

47 ± z-score*0.2

The confidence interval has been given as;

lower limit = 46.8%

upper limit = 47.2%

We can use any of these two values with the above expression to solve for the z-score. Using the lower limit we have the following equation;

47 - z-score*0.2 = 46.8

-z-score*0.2 = 46.8 - 47

-z-score*0.2 = -0.2

z-score = 1

The area of the standard normal curve between -1 and +1 will be the confidence level for the given confidence interval.

Pr( -1<Z<1 ) = 0.68 = 68%

From the Empirical rule
