X + y - 6 = 0 x - y - 8 = 0 When you eliminate y , what is the resulting equation?

alisha [4.7K]

When we eliminate y,(by adding here), resulting equation would be:

2x - 14 =0

So, x = 7

You can find the value of y as well, by substituting the value of x,
7 - y -8 = 0
y = -1

Hope this helps!

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t

NeX [460]

Answer:

0.09

Step-by-step explanation:

Given that 50% of this population prefers the color green.

Let p the probability that one person selected from the population prefer the green color of the car. So,

p=0.05

There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.

By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is

$P(r)=\binom{n}{r}p^{r}{(1-p)}^{n-r}\cdots(i)$

Here, 15 buyers are randomly selected, so, n= 15 and

$r= \frac1 3 \times 15=5$

So, by using equation (i), the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is

$P(r=5)=\binom{15}{5}(0.5)^{5}{(1-0.5)}^{15-5}$

$=\binom{15}{5}(0.5)^{5}{0.5}^{10}$

$=\binom{15}{5}(0.5)^{15}$

=0.0916

Hence, the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is 0.09.

Two dice are thrown simultaneously. Given that sum of the numbers is NOT more than 5, what is the probability that sum is more t

defon

A method to know the probability is to list down all of the possible combinations that would present an outcome of not more than 5. This is listed below:

1 + 4
4 + 1
2 + 3
3 + 2
1 + 1
2 + 2
1 + 2
2 + 1
1 + 3
3 + 1

There are 10 possible outcomes. But among these, the only ones that can have a sum more than 3 are:

1 + 4
4 + 1
2 + 3
3 + 2
2 + 2
1 + 3
3 + 1

There are only 7 possible outcomes that meet both requirements. Given that there are 7 outcomes within the total of 10, the probability would be 7/10, or 0.7.
