The solution set of the given equation is {(-1,-8),(3,4),(8,19)}.

<h3>Define solution set and domain.</h3>

The set of ordered pairs that make up the solution to an equation with two variables is referred to as the solution set.

In mathematics, a function's domain is the collection of possible inputs it will accept.

Given equation is 2y = 6x - 10 and domain is {-1, 3, 8}

We can also write the given equation is

y =(6x-10)/2      ------------equation 1

As we know, domain is considered as the value of x,

Consequently, if we enter x = -1 in equation 1, we will receive

y = (-16)/2

y = -8

Similarly put x = 3 in equation 1, we will get

y = 8/2

y = 4

Similarly put x = 8 in equation 1, we will get

y = 38/2

y = 19

By combining the values of x and y, we get

The solution set of the given equation is {(-1,-8),(3,4),(8,19)}.

lutik1710 [3]

Answer:

The probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Step-by-step explanation:

Let <em>X</em> = number of consumers comfortable having drones deliver their purchases.

The probability of the random variable <em>X</em> is, P (X) = <em>p</em> = 0.43.

Then <em>q</em> is, <em>q</em> = 1 - p

A sample of <em>n</em> = 5 consumers are selected.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.

The pmf of <em>X</em> is:

P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0,1,2,3...

Compute the value of P (X = 3) as follows:

P(X=3)={5\choose 3}0.43^{3}(1-0.43)^{5-3}\\=10\times 0.079507\times 0.3249\\=0.258318\\\approx0.2583

Thus, the probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Tracy bought 8 gallons of orange juice and used 1.8 gallons of it to make popsicles. How much orange juice does Tracy have left?
malfutka [58]

Answer:

6.2 gallons of orange juice left.

Step-by-step explanation:

Total orange juice = 8 gallons

Used orange juices to make popsicles = 1.8 gallons

We need to find how much orange juice does Tracy have left.

Left orange juice = Total orange juice - used orange juice

= 8 gallons - 1.8 gallons

= 6.2 gallons

Hence, 6.2 gallons of orange juice left.

What is an equation of the line that passes through the points (-2, -8) and has a slope of 3
Nana76 [90]

Answer:

y=3x-2

Step-by-step explanation:

Since we already know the slope, all we need to find is the y-intercept

The equation for a line is:

y=mx+b where m is the slope and b is the y-intercept. x and y are the x and y coordinates. We can use the numbers given in the problem and plug them into the equation...

y=mx+b

-8=3(-2)+b

-8=-6+b

b=-2

So the equation would be...

y=3x-2
