Answer:

correct

Step-by-step explanation:

The probability of landing on each color of the spinner is always one fourth. In Experiment 2, the probability of rolling each number on the die is always one sixth

Answer:

below

Step-by-step explanation:

You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.

A rectangle has a length of 8.3 cm and a perimeter of 22.4 cm.

Trava [24]

Answer:

the perimeter is simply 2L + 2W

So lengthy 8.3

2(8.3) + 2(w) =22.4

16.6=2(w) =22.4

2(w) = 5.8

w = 5.8 divide by 2

The width is 2.9

What is the missing term of ..9, __ , 19

VARVARA [1.3K]

Answer:

The answer could be anything, but if it's an arithmetical sequence, then it's 14.

Step-by-step explanation:

I'm assuming that the added numbers always stay the same, meaning it's linear. If you add 5 to 9, you get 14. If you add 5 again, you get 19. Another way of doing this is (19-9)/2 = 5, then 9+5=14.

A recent survey of students at John Tukey High School revealed that

RoseWind [281]

Answer:

0.5234 = 52.34% probability that at least three of these students are in favor of the proposal to change the dress code.

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they are in favor, or they are not. Students are independent. This means that we use the binomial probability distribution to solve this question.

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 combinations 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.

18% of the students are in favor of changing the dress code.

This means that $p = 0.18$

You randomly select 15 students

This means that $n = 15$

What is the probability that at least three of these students are in favor of the proposal to change the dress code?

This is

$P(X \geq 3) = 1 - P(X < 3)$

In which

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

In which

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

$P(X = 0) = C_{15,0}.(0.18)^{0}.(0.82)^{15} = 0.051$

$P(X = 1) = C_{15,1}.(0.18)^{1}.(0.82)^{14} = 0.1678$

$P(X = 2) = C_{15,2}.(0.18)^{2}.(0.82)^{13} = 0.2578$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.051 + 0.1678 + 0.2578 = 0.4766$

$P(X \geq 3) = 1 - P(X < 3) = 1 - 0.4766 = 0.5234$

0.5234 = 52.34% probability that at least three of these students are in favor of the proposal to change the dress code.

Which points are solutions to the linear inequality y < 0.5x + 2? Select three options.

Lisa [10]

Some solutions for the given linear inequality:

y < 0.5x + 2

are:

{(0, 1), (1, 2), (2, 2)}

<h3>Which points are solutions of the linear inequality?</h3>

Here we have the linear inequality:

y < 0.5x + 2

To find the points we can evaluate the right side, and then find values of y such that the inequality is true.

For example, if we use x = 0, then we get:

y < 0.5*0 + 2

y < 2

A value of y such that this is true is y = 1

Then the point (0, 1) is a solution of the inequality.

Another example can be with x = 1:

y < 0.5*1 + 2

y < 2.5

This time we can select y = 2, then the solution is (1, 2).

To get a final solution we can evaluate in x = 2

y < 0.5*2 + 2

y < 3

Then a possible solution is y = 2 again, so the solution is (2, 2).

Notice that for each of these values of x, there are a lot of other points that are solutions.
