By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.

About 6% of the population has a particular genetic mutation. 600 people are randomly selected. find the standard deviation for

Rina8888 [55]

Assume a binomial distribution. Then the mean of the distribution is $np$ , where $n$ is the number of people taken in a sample and $p$ is the probability of the mutation occurring in any given person, and the standard deviation is $\sqrt{np(1-p)}$ . Then in this case, the standard deviation is $\sqrt{600(0.06)(0.94)}\approx5.82$ .

Water is leaking out of a tank at a steady rate the tank started with 75 gallons after 15 hours the tank has 33 gallons of water

Natasha_Volkova [10]

Answer:

The equation will be " $y=-2.8 x+75$ ".

Step-by-step explanation:

The given values are:

Started with,

= 75 gallons

After 15 hrs,

Tank has,

= 33 gallons

Now,

The slope will be:

= $\frac{33-75}{15}$

= $\frac{-42}{15}$

= $-2.8$

Thus,

The equation is " $y=-2.5x+75$ ".

What is the slope of the line passing through the points (-3, 4) and (-3, -1)?

myrzilka [38]

Answer:

Undefined

Step-by-step explanation:

The equation for slope is:

$Slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}}$

Now we can plug in the given coordinates into the equation:

$Slope = \frac{-1-4}{-3-(-3)} =\frac{-5}{0}$

This means the slope is undefined and the line is vertical
