3n-5=-8(6+5n) in distributive property

Answers

Using distributive property we can expand the expression as

3n - 5 = -8 x 6 + (-8) x 5n

To apply the distributive property to the equation

3n - 5 = -8(6 + 5n), we need to distribute the -8 to the terms inside the parentheses.

Using the distributive property, we have:

3n - 5 = -8 x 6 + (-8) x 5n

Simplifying further:

3n - 5 = -48 - 40n

Now, we can continue solving the equation using the simplified form as

3n + 40n = -48 + 5

43n = -43

n= -1.

Answer:

n=-1

Step-by-step explanation:

3n-5=-8(6+5n)

3n-5=-48-40n

add 40n to both sides

43n-5=-48

distance = 500 feet

Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is

$(VW)/(YZ)$ = $(VX)/(YX)$ = $(WX)/(ZX)$

completing the required values gives

$(100)/(l)$ = $(60)/(30)$ ( cross- multiply )

60l = 30 × 100 = 3000 ( divide both sides by 60 )

l = 500

According to a recent survey of households, the poll found that 41 % of the adults watching a special event on TV enjoyed the commercials more than the event itself. Consider a random sample of nine adults who watched the special event. Complete parts a through d below.a. For this experiment, define the event that represents a "success".
i. A success is an adult who did not enjoy the commercials more than the event on TV itself.
ii. A success is an adult who enjoyed the commercials more than the event on TV itself.

b. What is the probability that less than four people enjoyed the commercials more than the event?
c. What is the probability that exactly six or seven people enjoyed the commercials more than the event?
d. What is the mean for this binomial distribution?

Answers

Answer:

a) ii. A success is an adult who enjoyed the commercials more than the event on TV itself.

b) P(X < 4) = 0.4576

c) P(X=6) + P(X=7) = 0.1064

d) Mean = 3.69

Step-by-step explanation:

a) The population parameter stated in the survey is the event that represents a success. Hence, A success is an adult who enjoyed the commercials more than the event on TV itself.

b) The probability that less than four people enjoyed the commercials more than the event

This is a binomial distribution problem

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = number of adults sampled = 9

x = Number of successes required = number of people that enjoyed the commercial more than the event on TV = less than 4

p = probability of success = probability of enjoying the commercial more than the event = 0.41

q = probability of failure = probability of NOT enjoying the commercial more than the event = 1 - 0.41 = 0.59

P(X < 4) = P(X=0) + P(X=1) + P(X=2) + P(X=3) = 0.00866299582 + 0.05418043148 + 0.15060323326 + 0.24419846296

P(X < 4) = 0.45764512351 = 0.4576

c) The probability that exactly six or seven people enjoyed the commercials more than the event = P(X=6) + P(X=7)

Using the Binomial distribution formula

P(X=6) + P(X=7) = 0.08194801935 + 0.02440582659 = 0.106353846 = 0.1064

d) Mean = expected value of people that would enjoy the commercial more than the main event = np = 9×0.41 = 3.69

Hope this Helps!!!

Answer:

a) ii. A success is an adult who enjoyed the commercials more than the event on TV itself.

b) $P(X=0)=(9C0)(0.41)^0 (1-0.41)^(9-0)=0.0087$

$P(X=1)=(9C1)(0.41)^1 (1-0.41)^(9-1)=0.0.54$

$P(X=2)=(9C2)(0.41)^2 (1-0.41)^(9-2)=0.151$

$P(X=3)=(9C3)(0.41)^3 (1-0.41)^(9-3)=0.244$

And adding we got:

$P(X<4) = P(X\leq 3) = P(X=0)+P(X=1) +P(X=2)+P(X=3)=0.0087+0.054+0.151+0.244=0.458$

c) $P(6 \leq X \leq 7)$

$P(X=6)=(9C6)(0.41)^6 (1-0.41)^(9-6)=0.082$

$P(X=7)=(9C7)(0.41)^7 (1-0.41)^(9-7)=0.0244$

And adding we got:

$P(6 \leq X \leq 7)=0.082+0.0244=0.106$

d) $\mu = np =9*0.41=3.69$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=9, p=0.41)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^(n-x)$

Where (nCx) means combinatory and it's given by this formula:

$nCx=(n!)/((n-x)! x!)$

Part a

The success on this case is:

ii. A success is an adult who enjoyed the commercials more than the event on TV itself.

Part b

For this case we want this probability:

$P(X<4) = P(X\leq 3) = P(X=0)+P(X=1) +P(X=2)+P(X=3)$

And we can find the individual probabilities and we got:

$P(X=0)=(9C0)(0.41)^0 (1-0.41)^(9-0)=0.0087$

$P(X=1)=(9C1)(0.41)^1 (1-0.41)^(9-1)=0.0.54$

$P(X=2)=(9C2)(0.41)^2 (1-0.41)^(9-2)=0.151$

$P(X=3)=(9C3)(0.41)^3 (1-0.41)^(9-3)=0.244$

And adding we got:

$P(X<4) = P(X\leq 3) = P(X=0)+P(X=1) +P(X=2)+P(X=3)=0.0087+0.054+0.151+0.244=0.458$

Part c

For this case we want this probability:

$P(6 \leq X \leq 7)$

$P(X=6)=(9C6)(0.41)^6 (1-0.41)^(9-6)=0.082$

$P(X=7)=(9C7)(0.41)^7 (1-0.41)^(9-7)=0.0244$

And adding we got:

$P(6 \leq X \leq 7)=0.082+0.0244=0.106$

Part d

For this case the mean is given by:

$\mu = np =9*0.41=3.69$

-10n + 3 = -117
Show work

Answers

Step-by-step explanation:

move the constant to the right hand side and change its sign

-10 +3= -117-3

calculate the difference

-10n= -120

divide both sides by -10

-10 = -120

N= 12

Answer:

$n = 12$

Step-by-step explanation:

1) Subtract 3 from both sides.

$- 10n = - 117 - 3$

2) Simplify -117 - 3 to - 120.

$- 10n = - 120$

3) Divide both sides by -10.

$n = ( - 120)/( - 10)$

4) Two negative makes a positive.

$n = (120)/(10)$

5) Simplify 120/10 to 12.

$n = 12$
