Which statement is true about this equation?
-(2x + 4) + x = 3x − 4x − 4
The equation has one solution, x = 0.
The equation has one solution, x = 4.
The equation has no solution.
The equation has infinitely many solutions.
Answers
Answer:
4th option
Step-by-step explanation:
Given
- (2x + 4) + x = 3x - 4x - 4 ← simplify both sides
- 2x - 4 + x = - x - 4
- x - 4 = - x - 4
Since both sides are equal then the equation has infinitely many solutions
Answer:
No solution
Step-by-step explanation:
First you would start off by multiplying the -1 into the 2x and 4 which equals -2x and -4 then you would combine like terms on both sides. This leaves you with -1x-4=-1x-4. You would now subtract the -1 to the other side of the equal sign which leaves -4=-4 there for having no soultion
consider the population described by the probability distribution shown in the table. the random variable x is observed twice. find E(x)
Answers
The expected value (E(x)) of the random variable x is 1.4. It is calculated after multiplying each value by it's probability.
To find the expected value (E(x)) of a random variable, you need to multiply each possible value by its corresponding probability and then sum them up.
In the given probability distribution table, the possible values for the random variable x are 0, 1, 2, and 3. The corresponding probabilities are 0.2, 0.3, 0.4, and 0.1 respectively.
To find E(x), we multiply each value by its probability and sum them up:
E(x) = (0 * 0.2) + (1 * 0.3) + (2 * 0.4) + (3 * 0.1)
= 0 + 0.3 + 0.8 + 0.3
= 1.4

what is the correct way to measure the zone of inhibition?
Answers
The correct way to measure the zone of inhibition is to place a known amount of an antimicrobial agent on a solid medium.
What is Area?Area is a quantity that measures the size of a two-dimensional surface or shape. It is expressed in square units such as square centimetres (cm2), square metres (m2) or square kilometres (km2). Area is used to describe the size of a garden, a house, a room, a city and much more. It can also be used to calculate the amount of material required for a project, such as paint, carpet or tiles. Knowing the area of a shape can help to calculate costs, and to make sure that enough materials are ordered.
The zone of inhibition is then measured as the area surrounding the antimicrobial agent where microbial growth has been inhibited. This area is typically measured in millimeters. To accurately measure the zone of inhibition, it is important to ensure that the size of the inoculum and the amount of antimicrobial agent used remain constant. Additionally, it is important to consider the type of organism being studied, as different organisms can have different levels of susceptibility to the antimicrobial agent. Finally, the medium used should be appropriate for the organism being studied, as different media can produce different results.

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 9.7% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 9.7% of his customers buy a magazine is correct, what is the probability that exactly 5 out of the first 10 customers buy a magazine?
Answers
The probability that exactly 5 out of the first 10 customers buy a magazine is 0.00126.
Given suspicion of 9.7% that buy a magazine is correct.
We have to find the probability that exactly 5 out of the first 10 customers buy a magazine. Probability is the chance of happening an event among all the events possible.
The binomial distribution 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 \(C_{n,x}=n!/x!(n-x)!\)
And P is the probability of happening of X.
In the question 9.7% of his customers buy a magazine.
So the value of P=0.097
This can be calculated by :
P(X=5) when n=13
\(P(X=x)=C_{n,x} p^{x} (1-p)^{n-x}\)
\(P(X=5)=C_{10,5} (0.097)^{5} (1-0.097)^{10-5}\)
=\(P(X=5)=C_{10,5} (0.097)^{5} (0.903)^{5}\)
\(=10!/5!5!*0.0000085*0.600397\)
=252*0.00000510
=0.001286
Hence the probability that exactly 5 out of the first 10 customers buy a magazine is 0.001286.

To give their animals essential minerals and nutrients, farmers and ranchers often have a block of salt—called "salt lick"—available for their animals to lick. A rancher is ordering a box of cube-shaped salt licks. The edge lengths of each salt lick are 3/5 foot. What is the volume of each salt lick? Volume = length x width x height
Answers
The volume of each cube-shaped salt lick is 0.216 cubic feet.
1. The given information states that the edge lengths of each salt lick are 3/5 foot.
2. To calculate the volume of a cube, we need to multiply the length, width, and height of the cube. However, in the case of a cube, all three dimensions are the same because each side of a cube has equal length.
3. In this case, the edge length of each salt lick is 3/5 foot. Since all edges of the cube have the same length, we can consider this length as the length, width, and height of the cube.
4. To find the volume, we need to raise the edge length to the power of 3 (cubed). Mathematically, it can be represented as follows:
Volume = (Edge length)³
Substituting the given edge length of 3/5 foot:
Volume = (3/5)³
Volume = (3/5) * (3/5) * (3/5)
Volume = 27/125
5. The result of the calculation is 27/125. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 1 in this case.
Dividing both 27 and 125 by 1:
Volume = 27/125
Volume = 0.216
6. Therefore, the volume of each cube-shaped salt lick is 0.216 cubic feet.

The number of apples Chee bought is 2, and the number of peaches she bought is 8
Solving System of Linear Equations GraphicallyFrom the question, we are to determine the number of apples, x, and the number of peaches, y, that Chee bought
From the given information,
She bought $6 worth of apples and peaches
and
Each apple costs $1 and each peach costs $0.50
Then, we can write that
$1 × x + $0.50 × y = $6
x + 0.50y = 6
Also,
She bought 4 times as many peaches as apples
That is,
y = 4x
Now, we will solve the system of equations graphically
x + 0.50y = 6
y = 4x

The table below shows the relationship between the number of cars sold and the amount of money earned by the car salesperson. Is the amount of money earned, in dollars, proportional to the number of cars sold?
Answers
Answer:
No, it is not proportional.
Step-by-step explanation:
This can be determined by looking at the first two items in the chart. I have looked at them all to find a certain pattern, but there wasn't any. The salesman earns $250 for one car sale, and he also earns $600 for two car sales, while this seems like it's just adding a $100 bonus, if you look at the third item on the chart adds a $200 bonus. You could be thinking that this is just adding a $100 bonus for how many cars were sold before, but then you move onto the fourth item on the chart. Which would give you $1,300 if the pattern was continued, yet instead the amount listed is $1,076.
Alex and Case are starting their own businesses. Alex has $52 from pre-orders and plans on selling the mittens he made for $4 each pair. Case has $35 from pre-orders and plans on selling the mittens he made $5 each pair. Which equation could you use to determine when Alex and Case will have the same amount of money?
Answers
Answer:
Equation could you use to determine when Alex and Case will have the same amount of money is \(52+4x=35+5x\)
Step-by-step explanation:
Let x be the pairs of mittens when Alex and Case will have the same amount of money
Alex has amount before orders = $52
He will sell 1 pair of mittens = 4
He will sell x pair of mittens = 4x
So, Alex's total amount = 52+4x
Case has amount before orders = $35
He will sell 1 pair of mittens = 5
He will sell x pair of mittens = 5x
So, Case's total amount = 35+5x
ATQ
52+4x=35+5x
52-35=x
17=x
Hence the pairs of mittens when Alex and Case will have the same amount of money is 17 and equation could you use to determine when Alex and Case will have the same amount of money is \(52+4x=35+5x\)
