54.8 m= ? km? how did you solve? do you place the zeros in front or behind the number? where does my decimal go and why does it

Maru [420]

M is smaller than km
1000m=1km

so divide by 1000
basically move decimal 3 places to left
put zero in front
0.0548km

A TV show, Lindsay and Tobias, recently had a share of 20, meaning that among the TV sets in use, 20% were tuned to that show. A

kati45 [8]

Answer:

8.6% probability that none of the households are tuned to Lindsay and Tobias.

There is a 91.4% probability that at least one household is tuned to Lindsay and Tobias.

There is a 32.2% probability that at most one household is tuned to Lindsay and Tobias.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they are watching the TV show, or they are not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

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

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

And p is the probability of X happening.

In this problem we have that:

$n = 11, p = 0.20$

Find the probability that none of the households are tuned to Lindsay and Tobias.

This is P(X = 0).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{11,0}.(0.20)^{0}.(0.80)^{11} = 0.086$

8.6% probability that none of the households are tuned to Lindsay and Tobias.

Find the probability that at least one household is tuned to Lindsay and Tobias.

Either no household is tuned, or at least one is tuned. The sum of the probabilities of these events is decimal 1. So

$P(X = 0) + P(X \geq 1) = 1$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.086 = 0.914$

There is a 91.4% probability that at least one household is tuned to Lindsay and Tobias.

Find the probability that at most one household is tuned to Lindsay and Tobias.

This is

$P(X \leq 1) = P(X = 0) + P(X = 1)$

$P(X = 1) = C_{11,1}.(0.20)^{1}.(0.80)^{10} = 0.236$

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.086 + 0.236 = 0.322$

There is a 32.2% probability that at most one household is tuned to Lindsay and Tobias.

Rewrite the equation in slope intercept form 7x + 9y = 9

shtirl [24]

Answer:

y = -7/9 x +1

Step-by-step explanation:

7x + 9y = 9

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

Subtract 7x from each side

7x -7x+ 9y =-7x+ 9

9y = -7x+9

Divide each side by 9

9y/9 = -7/9 x +9/9

y = -7/9 x +1

The slope is -7/9 and the y intercept is 1

How many years does it take to earn a million dollars if you are paid 30 dollars an hour and work 35 hours a week for 50 weeks a

Anettt [7]

Ok so find how much you earn per year
30 times 35 times 50=amount earned per year=52500 per year

so
1 million=1,000,000
so
52500 times how many years=1,000,000
divide both sides by 52500
how many years=19.04 so about 19 years
