Solve the equation 12v+10v+14=80

Mathematics
1 answer:
Roman55 [17]3 years ago
8 0

Answer:V=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12v+10v+14=80

(12v+10v)+(14)=80

(Combine Like Terms)

22v+14=80

22v+14=80

Step 2: Subtract 14 from both sides.

22v+14−14=80−14

22v=66

Step 3: Divide both sides by 22.

22v/22=66/22

V=3

Find the solution to the system 9x−4y=−13 and 9x−2y=−20
BaLLatris [955]

Answer:

x = -3, y = -3.5.  As an ordered pair it is (-3, -3.5).

Step-by-step explanation:

9x − 4y = −13

9x − 2y =  -20

Subtract:-

-2y = 7

y = -3.5.

Substitute for y in the first equation:

9x - 4(-3.5) = -13

9x =  -27

x = -3.

Ulleksa [173]

Answer:

P(X=3) = 0.2013

Step-by-step explanation:

After taking and tagging the first 20 birds, then we have a proportion of 20% of tagged birds within the population, that is

p=\frac{n}{N}

p=\frac{20}{100}=0.20

Supposing that the probability (0.20) of capturing a bird <em>remains constant</em>, we may resolve it as it follows:

Capturing 10 birds can be considered as a binomial experiment with a success probability p = 0.2

Let, P(X=x)=nCx*p^{x}*(1-p)^{n-x} be the expression of the binomial distribution, for our case we have:

p=0.2

x = 3

n=10

Then,

P(X=3)=10C3*0.2^{3}*0.8^{10-3}

P(X=x)=0.2013

Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%

What is the domain of f(x)=3x-4
klemol [59]

Answer:

There are no domains so 0

Step-by-step explanation:

The domain of any function is simply all the possible numbers you can input for   x

without violating the rules of math.

we cannot have a negative number for x (its against the laws of math), so the domain would be all non-negative numbers

:) Hoped this helped
