Answer and step-by-step explanation:

I am assuming the equation is:

y + 2 = -\frac{3}{4}(x + 4)

It will be easier if we convert the fraction to a decimal, for now.

y + 2 = -0.75(x + 4)

Then we can simplify a bit, using the distributive property.

y + 2 = -0.75x - 3

Now, we want to have the y all by its self. So, let's subtract 2 on both sides.

y + (2 - 2) = -0.75x + (-3 - 2)

y = -0.75x - 5

Let's convert the decimal back into a fraction.

y = -\frac{3}{4}x - 5

Now we have our equation. To start graphing, let's plot the y-intercept. Our y-intercept is -5. So we can plot the point (0, -5). Now, we need to find the slope. The slope is -\frac{3}{4}. It's negative, which means that the line will start from the top right to the bottom left. That means that every time we move to the right one unit, we will move down 0.75 units. I hope this helps!

Certify Completion Icon Tries remaining:2 A town recently dismissed 10 employees in order to meet their new budget reductions. T

Answer:

0.055 = 5.5% probability that exactly 5 employees were over 50.

Step-by-step explanation:

The employees are removed from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

7 + 18 = 25 employees, which means that N = 25

7 over 50, which means that k = 7

10 dismissed, which means that n = 10

What is the probability that exactly 5 employees were over 50?

This is P(X = 5). So

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

P(X = 5) = h(5,25,10,7) = \frac{C_{7,5}*C_{18,5}}{C_{25,10}} = 0.055

0.055 = 5.5% probability that exactly 5 employees were over 50.

What two numbers multiply to -50 and add up to -23
umka2103 [35]

Answer:

-25 and 2

Step-by-step explanation:

x + y = -23

xy = 50, so y = 50 /x

.

x + 50/x =-23,  x^2 +23x - 50 = (x-2)(x+25)

so 2 and -25

vovangra [49]
3x+y=4\ \ \ \ \ \ ..............equation(1)\\x-3y=4\ \ \ \ \ \ ..............equation(2)\\\\ Using~equation~(2), \\\\
x-3y=4\\x=4+3y\\\\Now,\ using\ the\ value\ of\ x\ in\ equation\ (1),\ we\ get,\\\\(4+3y)-3y=4\\\\4=4

Since all the variables cancel out and the coefficient equal to eachother, this system of equation has <u>infinitely many solutions!</u>
