Answer:
1/4
Step-by-step explanation:
So lets go over our information
We know there are 6 pocket
1 of them has 10 dollars
2 have been checked
There are 4 more to check
There is a 1 in something chance of the next pocket having 10 dollars.
The key here is, 2 have already been checked.
This means there is a 1/4 chance of the next pocket having 10 dollars.
Answer:
B(1/4)

Consider the following two questions designed to assess quantitative literacy.
What is 15% of 1000?
A store is offering a 15% off sale on all TVs. The most popular television is normally priced at $1000. How much money would a customer save on the television during this sale?
Suppose the first question is asked of 200 randomly selected college students, with 168 answering correctly; the second one is asked of a different random sample of 200 college students, resulting in 147 correct responses. Carry out a test of hypotheses at significance level 0.05 to decide if the true proportion of correct responses to the question without context exceeds that for the one with context. (Use p1 for the true proportion students who answered the question without context correctly and p2 for the true proportion of students who answered the question with context correctly.)
State the relevant hypotheses.
H0: p1 − p2 = 0
Ha: p1 − p2 < 0H0: p1 − p2 = 0
Ha: p1 − p2 ≠ 0 H0: p1 − p2 = 0
Ha: p1 − p2 > 0H0: p1 − p2 < 0
Ha: p1 − p2 = 0H0: p1 − p2 > 0
Ha: p1 − p2 = 0
Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)
z=P-value=
State the conclusion in the problem context.
Fail to reject H0. The data does not suggest that the true proportion of correct answers to the context-free question is higher than the proportion of right answers to the contextual one.Reject H0.

You may need to use the appropriate table in the Appendix of Tables to answer this question.
Answer:
A customer would save $ 150 on the television during this sale and pay
$ 850.
Reject H0. The data suggests that the true proportion of correct answers to the context-free question is higher than the proportion of right answers to the contextual one
Step-by-step explanation:
15% of 1000
=0.15 *1000= $ 150
A customer would save $ 150 on the television during this sale.
p1 = the true proportion students who answered the question without context = 168/200
p2 = the true proportion of students who answered the question with context correctly = 147/200
The null and alternate hypotheses are
H0: p1 − p2 = 0 i.e the true proportion of correct responses to the question without context is the same as that for the one with context
against the claim
Ha: p1 − p2 > 0 that is the true proportion of correct responses to the question without context exceeds that for the one with context
2) The significance level is set at 0.05
3) The critical region is z > ± 1.645
4) The test statistic
Z= p1-p2/ sqrt [pcqc ( 1/n1+ 1/n2)]
Here p1= 168/200= 0.84
and p2= 147/200=0.735
pc = 168+147/200+200
pc= 315/400= 0.7875
qc= 1-pc= 1-0.7875=0.2125
5) Calculations
Z= p1-p2/ sqrt [pcqc ( 1/n1+ 1/n2)]
z= 0.84-0.735/√ 0.7875*0.2125( 1/200+ 1/200)
z= 0.105/0.0409076
z= 2.5667
6) Conclusion
Since the calculated value of z= 2.5667 lies in the critical region the null hypothesis is rejected and it is concluded that the true proportion of correct responses to the question without context exceeds that for the one with context.
The value of z is 2.5668.
The value of p is 0.01016

Answer:
X = 2/3
Step-by-step explanation:
there is some misinformation here but I’m just gonna assume these rectangles are proportional.
If the longer side for the first one is 3 and the longest side for the second is 2 meaning that the second side is multiplied by 2/3
So if we multiply 1 by 2/3, it will be 2/3 meaning x = 2/3

what is triangle?Three sides and three vertices make up a triangle, which is a polygon. It is among the fundamental forms in geometry. Triangle ABC is a graphical representation of a triangle having vertices A, B, and C. In Euclidean geometry, any three points identify a distinct triangle and, concurrently, a distinct plane if they are not collinear.

Which conditional statement has a false converse? If a figure is a square, then it has four sides. If a point has x-coordinate 0, then it lies on the y-axis. If two angles are congruent, then they have the same measure. If two planes are parallel, then they have no points in common.
The conditional statement has a false converse will be the four-sided polygon may be square. Then the correct option is A.
What is the conditional statement?There have been two main categories of arguments in the studies of logic: conditional statements and polyamorous statements. These assertions, which are referred to as compound statements, are created by combining two other statements.
The converse statement should also be true when its condition is reversed.
Let's check all the options. Then we have
A. If a figure is a square, then it has four sides. The converse of the statement is false.
B. If a point has an x-coordinate 0, then it lies on the y-axis. The converse of the statement is true.
C. If two angles are congruent, then they have the same measure. The converse of the statement is true.
D. If two planes are parallel, then they have no points in common. The converse of the statement is true.
The conditional statement has a false converse will be the four-sided polygon may be square. Then the correct option is A.

A tank is 80c ,nu 60cm by 75cm, find the volume of water that will fill up
A tank that is 80 cm tall and has a base that is 60 cm by 75 cm.
To find the volume of the tank, you can use the formula for the volume of a rectangular prism, which is:
Volume = length * width * height
Using the dimensions given, we can plug them into the formula as follows:
Volume = 60 cm * 75 cm * 80 cm = 4,500 cm^3
This means that the tank has a volume of 4,500 cubic centimeters, and it would take 4,500 cubic centimeters of water to fill it up

Answer:
Step-by-step explanation:
To find the volume of water that will fill up a tank that is 80 cm tall, 60 cm wide, and 75 cm deep, you can use the formula for the volume of a rectangular prism. The formula for the volume of a rectangular prism is length x width x height, so in this case, the formula would be:
60 cm x 75 cm x 80 cm = 36,000 cm^3
So the volume of water that will fill up the tank is 36,000 cubic centimeters.
Alternatively this also can be written as 806075 cubic cms

What are consecutive integers?Consecutive integers are whole numbers that follow each other without gaps. For example, 15, 16, 17 are consecutive integers.
Given that, what are four consecutive even integers if the first integer is −4
We know that, Consecutive even integers are even integers that follow each other, and they differ by 2. If x is an even integer, then x + 2, x + 4 and x + 6 are consecutive even integers.
Therefore, here x = -4,
-4+2 = -2
-4+4 = 0
-4+6 = 2

but i dont know why theres a 45 :(
Length of missing side is 36 units.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
Let length of missing side is x
Since horizontal lines are parallel, so ratio of sides are equal
20/16 = 45/x
x= (45/20)16
x = 36
Hence, length of missing side is 36 units.
