The blue line has a slope of 1 and a y-intercept at 0. In slope intercept form, this equation is y = x. The line is solid and not dashed. This means the inequality could include numbers ON the line itself. The shading is on the left side of the line so it's a greater than equation.

The blue inequality is y ≥ x.

The red line has a slope of 0 and a y-intercept at 6. Slope-intercept form: y = 6 The line is solid and not dashed meaning numbers on the line are again included. The shading is below the horizontal line created so it is a less than inequality.

The red inequality is y ≤ 6

Your system of linear inequalities would be:

y ≥ x

y ≤ 6

Two balls are drawn in succession out of a box containing 5 red and 5 white balls. Find the probability that at least 1 ball was

Lera25 [3.4K]

Check the tree diagram of the problem:

The first ball can be either Red or Blue, the second ball can either be Red or Blue.

The branches represent all possible scenarios.

For example, consider the upper branch, the case when both balls are blue:

The first ball is Blue, probability 5/10, the second ball is Blue, probability 4/9 because now there are 4 left blue balls, and 9 balls in total, after we picked the first blue.

The other branches have the same logic.

The question is not completed so we have 2 cases:

"Find the probability that at least 1 ball was red, given that the first ball was red"

here we add the separate probabilities of (R, R) and (R, B)

P(R,R)+P(R,B)=2/9 + 5/18 = 4/18 +5/18= 9/18=0.5

"Find the probability that at least 1 ball was red, given that the first ball was blue"

probability is P(B, R)=5/18=0.28

Explain why you should récord a 1 in the tens columna when you regroup in addition problem

ser-zykov [4K]

You should write a 1 because I f what you add is 11, 12, 13, 14, 15, 16, 17, 18, or 19 there is a 1 in the front of the numbers so you must put a 1 but if the number was 76 the number in the front is 7 so you would put 7 on the tens column.

In the 2000 presidential election, three candidates split the vote as follows:

Lera25 [3.4K]

Answer:

c 23 and 0.46 are statistics and 0.484 is a parameter

True. For this case the value 0.46 represent t statistic since from the sample obtained we can calculate the sample proportion of people who voted for Gore like this:

$\hat p_{Gore]=\frac{X}{n}=\frac{23}{50}=0.46$

Where X represent the people with the characteristic desired in the random sample selected.

So then we can say that 23 and 0.46 represent statistics since comes from the sample. And the value 0.484 is obtained from the population so then represent a parameter.

Step-by-step explanation:

Previous concepts

A parameter is any "numerical quantity that characterizes a given population or some aspect of it". For this case we are interested on proportions and we denote the population proportion by $p$

A statistic is "used to estimate the value of a population parameter". In other words is just an estimation of the population parameter of interest. Four our case the sample proportion denoted by $\hat p$ represent the statistic for this case.

Solution for the problem

a 0.46 and 0.484 are statistics

False. 0.484 is not an statistic since it's the outcome from the original population and would represent the parameter "proportion of people who vote for Gore"

b 50 and 23 are statistics and 0.484 is a parameter

False. The sample size is not an statistic is just a value selected in order to calculate the statistic.

c 23 and 0.46 are statistics and 0.484 is a parameter

True. For this case the value 0.46 represent t statistic since from the sample obtained we can calculate the sample proportion of people who voted for Gore like this:

$\hat p_{Gore]=\frac{X}{n}=\frac{23}{50}=0.46$

Where X represent the people with the characteristic desired in the random sample selected.

So then we can say that 23 and 0.46 represent statistics since comes from the sample. And the value 0.484 is obtained from the population so then represent a parameter.
