polynomial of y=(x-2x -1)(х+3)​

Answer:

a) p = -84

b) m = 23

Step-by-step explanation:

p = -4

a = 19 + 2p  

⇒ 19 + 2 x -4

⇒ -84

m = 3

[tex]m^{3}[/tex] - 4

⇒ [tex]3^{3}[/tex] - 4

⇒ 23

Answer: Cluster Sampling

Step-by-step explanation: I just took this test and got it correct :)

If the researchers choose three freshmen seminar classes at random and poll every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

In the probability sampling technique known as cluster sampling, you split a population into groups, such as districts or schools, and then randomly choose a sample from among these groups. Ideally, each cluster should be a small representation of the population as a whole.

When studying large, dispersed populations, cluster sampling is most effective since interviewing every individual would be expensive, time-consuming, and sometimes impossible.

By using cluster sampling, it is possible to create smaller, more comparable clusters that represent the population being studied.

Thus, the researchers choose three freshmen seminar classes at random and polled every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

Answer:

60.000 litres

Step-by-step explanation:

If a cow produces 25 liters of milk a day, 240 cows bring how many liters a day

240×25=x

x=6.000

If 240 cows produce 6000 liters of milk per day, how many liters per year they produce

have the potential to give milk for 10 months a year

6000×10=60.000 litres

Step-by-step explanation:

Answer:

z = -11

Step-by-step explanation:

-5Z = 55

to find z, divide each side by -5

[tex]\frac{-5Z}{-5} = \frac{55}{-5}[/tex]

z = -11

Answer:

Z = -11

Step-by-step explanation:

When dealing with variables, you want to get it alone so it instantly equals the number.

Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.

Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!

                                                 -5Z = 55

                                                  /-5     /-5

                                                   Z =  -11

Just in case, we'll plug in -11 for Z and see if it works.

                                               -5(-11) = 55

Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!

The cost of each friendship bracelet in dollars and cents was J $7.75

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.

Cost of 8 friendship bracelets =  $62.00

Therefore,

Cost of 1 friendship bracelets =  $62.00/ 8

Cost of 1 friendship bracelets =  7.75

The cost of 1 friendship bracelets is $7.75

Answer:

Approximately 460 ft

Step-by-step explanation:

In any question where we have:

And we're asked to find:

We're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:

And we're looking for:

How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:

[tex]\tan{49^\circ}=h/400[/tex]

Solving for h, we find that

[tex]h=400\tan{49^\circ}\approx400(1.15)=460[/tex]

So the heigh of the hill is approximately 460 ft.
