what value of x the given expression is undefined x+4/x-4
Answer:
At x= 4 the given expression is undefined.
Step-by-step explanation:
In a given function , if the denominator becomes zero then the function is undefined.
Here, denominator is x-4 so at x = 4 it will become zero. So we can say that at x=4 , the function is undefined

Answer: Choice C) Upper right corner (aka northeast corner)
====================================================
Explanation:
Rational numbers are ones where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.
Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.
Of the four answer choices, only choice C is correct.
Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.
Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.
Vishal was interested in the relationship between a person's age and their musical preferences. He called all
the numbers listed in his city's telephone directory, and whenever someone answered and agreed to be
surveyed, he asked them for their age and interviewed them about their musical preferences.
Once he was done, he analyzed his results and found that younger people prefer pop and hip-hop music
while older people prefer jazz and classical music.
What type of statistical study did Vishal use?
Choose 1 answer:
Sample study
Experiment
Observational study
Answer:
Sample study
Step-by-step explanation:
Sample study is a type of statistical study that is done by taking samples from respondents for any research purpose.
In this type of statistical study, a group of people are selected and asked some questions or data collected.
The type of statistical study that Vishal used was Sample Study because he collected data from a group of respondents to arrive at a hypothesis.
Vishal study of relationship between people's age & musical preferences is 'Observational Statistical Study'
Given : Vishal approached all people in city, enquired willing ones about age & musical preferences, & analysed conclusion thereafter.
Vishal used Observational Statistical Study, as :
Sample study denotes - component step of choosing few representatives ie sample units from all ie population units. It is a part of all statistical studies, & not a type of study in itself. Observational Study - involves studying the sample units in natural uncontrolled or un intervened setup , based on the variable/ traits or relationship study needed by nature of study. Experimental Study - involves studying & analysing variables traits or relationships, in manipulated, controlled or artificially treated experiment setup.Vishal collects sample from his city & studies them as it is, without any artificial intervention. Hence this natural enquiry based study of age & musical preferences is Observational Study

Based on the cost of two pounds of sugar, we can calculate the quantity of sugar to a dollar to be 0.7 pounds.
Sugar per dollarYou can find out the quantity of sugar you get per dollar using the formula:
= Price of sugar / Number of pounds
Solving gives
= 1.40 / 2
= 0.7 pounds
In conclusion, you get 0.7 pounds.

How would you write an explanation for a, b, and c? Mississipi is the data point on the upper left that is an outlier
Step-by-step explanation:
a. Your answer is correct. The trend is that obesity rate increases with the number of fast food restaurants per capita. Since Mississippi has a high obesity rate and number of fast food restaurants per capita, it goes against the trend. It is an outlier in terms of the relationship.
b. The number of restaurants per capita is between 2 and 6 for most states. Mississippi's number of restaurants per capita is within this range, so it is not an outlier.
c. The obesity rate is between 22 and 38 for most states. Mississippi's obesity rate is within this range, so it is not an outlier.

Luke Skywalker mixes bantha milk that is 16% protein with tauntaun milk that is 9% protein. How many pounds of each should he mix to get a 350-pound mixture that is 12% protein?
b = amount of bantha milk
t = amount of tauntaun milk
b + t = 350
0.16 b + 0.09 t = 0.12(b + t) = 42
t = 350 - b
0.16 b + 0.09 (350 - b) = 42
0.16 b + 31.5 - 0.09 b = 42
0.07 b = 10.5
b = 150
t = 200
Find the value of x.
Answer:
x=20°
Step-by-step explanation:
This is actually simpler than it seems. Try redrawing (or maybe just imagine) that the only inscribed angle is x with the two lines going to the 40°. If we let 40°=θ, then: x=θ/2
This is actually true for any situation with inscribed angles, so you could use this to find w, y, and z as well.
Anyways x=(40°)/2=20°, so x=20°

Answer:
its B, C and E
Step-by-step explanation:
on edge
Answer:
2a + 3p = 18
Step-by-step explanation:
The total has to equal 18 so then you have $2 and $3. Apples cost $2 so the 2 should have an a for Apples. The peppers cost $3 so the 3 should have a p for peppers. So the equation would be 2a + 3p = 18.

d(n) = 6 - 4(n - 1) find the 5th term in the sequence
d(n) = 6 - 4(n - 1)
Plug 5 into the equation for n.
d(5) = 6 - 4(5 - 1)
Subtract 1 from 5
d(5) = 6 - 4(4)
Multiply 4 by 4
d(5) = 6 - 16
Simplify the right side
d(5) = -10
The fifth term in the sequence is -10
The 5th term of the sequence is -10.
What is a sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Given is a sequence, d(n) = 6 - 4(n - 1)
To find the 5th term, put n = 5
d(5) = 6-4(5-1)
= 6-4×4
= 6-16
= -10
Hence, the 5th term of the sequence is -10.

An ordinary 52-card deck is thoroughly shuffled. You are dealt four cards. (a) What is the probability that all four cards are sevens. (b) What is the probability that at least one of the cards is a seven. (c) What is the probability that none of them are seven. (d) What is the probability that two out the four cards is a seven
Answer:
a) The probability of getting a seven is 4/52
b) At least one of the cards is a seven=0.2813
c) The probability that none of them are seven= 0.7187
d) The probability that two out the four cards is a seven= 0.043
Step-by-step explanation:
A deck contains 52 cards containing 4 sets of 13 cards . Each set has a seven card in it. Thus there are 4 seven cards in a deck of 52 cards.
a) The probability of getting a seven is 4/52=0.0769
b) At least one of the cards is a seven=
1- P(no seven)
= 1- 4C0 * 48C4/ 52C4= 1- 0.7187= 0.2813
c) The probability that none of them are seven=4C0 * 48C4/ 52C4= 0.7187
d) The probability that two out the four cards is a seven= First card is seven * second Card is seven * two cards are not seven
= 4/52* 3/51*48/50= 0.0769*0.0588*0.96= 0.043
