Which graph represent the equation y=-2

yes, if you do 94/9 you get about 10%. this determines that out of all 94 responses, by dividing it by the 9 people who prefer organic food, you get 10.444 percent which is approximately 10%

The pet store owner's conclusion about her customers' preference for organic pet food is not entirely valid due to the small sample size and potential bias in her survey results. For more accurate conclusions, she should get responses from a larger, more diverse group of customers.

The pet store owner's conclusion is not entirely valid because it is based on the assumption that the 94 responses she received are representative of her entire customer base. While 9 out of 94 responses did indicate a preference for organic pet food, this is a small sample size and may not accurately reflect the preferences of all customers. For a more accurate estimate, she would need to collect responses from a larger and more diverse group of customers, to allow the results to be more statistically significant.

A small sample size can lead to inaccuracies or bias in survey results. In addition, because these customers self-selected to respond tot he survey, they may not represent the full spectrum of her customers. This type of bias is known as a self-selection bias.

So, while it's a starting point, further sampling and more robust survey methods would help strengthen the validity of her conclusions about her customers' pet food preferences.

Answer:

x=0.27

Step-by-step explanation:

The given expression is

[tex]e^{\frac{1}{4}x}=|4x|[/tex]

To solve this equation, we graph the functions:

[tex]f(x)=e^{\frac{1}{4}x}[/tex]

and

[tex]g(x)=|4x|[/tex]

From the graph, the two curves intersects at x=-0.24 and x=0.27.

But the domain of the logarithmic function is x>0

Therefore x=0.27

-0.25 and 0.25.

That is already estimated.

Answer:

Negatively skewed.

Step-by-step explanation:

In a negatively skewed distribution, the mode is greater then the median, and the median is greater then the mean. Overall, the majority of the data is to the right, which means that the distribution of data is skewed to the left, or negatively skewed.

Answer: Hence, Option 'C' is correct.

Step-by-step explanation:

As we know that if one tail is longer than the other, the distribution is said to be skewed.

And there are two types of skewed  distribution :

1) Negatively skewed

2) Positively skewed

It depends on the direction of the long tail.

If the long tail is to the right , then it is said to be positively skewed distribution.

If the long tail is to the left , then it is said to be negatively skewed distribution.

According to question, the distribution  here is a positively skewed distribution.

Hence, Option 'C' is correct.

The transformation of Figure 1 results in Figure 2 is Rotation.

A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The Pre-Image is the original shape of the object, and the Image during the transformation is the final shape and location of the object.

Transformations in geometry are categorized into three;

As we translate, we move a figure in any direction.

When we flip a figure over a line, we call this reflection.

When we rotate a figure a given amount around a point, we call this rotation.

As we dilate, we enlarge or contract a figure.

B. Addition Property of Equality justified the statement,

"If WX=YZ, then WX+RS=YZ+RS".

Facts regarding any two or more quantities connected by the equal sign are known as properties of equality.

There are four types of properties of equality.

Addition property, when two equal quantities are increased by a common value, the equality is preserved.

Transitive property of equality, entities that are equivalent to one another are also equivalent to one another.

Subtraction property, equality is maintained when a common term is subtracted from two equal terms.

Multiplying by a common term do not alter the equality, according to the multiplication property of equality.

Given, An equation WX = YZ, Now, In this expression WX + RS = YZ + RS

We have added RS to both side of the equation to maintain the equality sign.

Answer: Option A

A. 0.98

Step-by-step explanation:

Plan A consists of:

Plan A: treat with antibiotics 1. If not effective, treat with antibiotics 2

Antibiotic 1 has a probability P (1) of 0.8 to be effective

Antibiotic 2 has a probability P (2) of 0.9 to be effective.

For a patient to be treated successfully with plan A it can happen that:

The antibiotic 1 works, or that the antibiotic 1 does not work but the 2 antibiotic if it works.

So the probability that plan A works is:

[tex]P = P (1) + P (not\ 1) P (2)\\\\P = 0.8 + (1-0.8) (0.9)\\\\P = 0.8 + 0.2 * 0.9\\\\P = 0.98[/tex]

The probability of a patient being successfully treated under plan A, which involves treatment with antibiotic 1 and then antibiotic 2 if the first fails, is 0.98, or 98%.

The probability that a patient treated under plan A will be successfully treated is calculated by summing the probabilities of success in each step. Initially, the patient is treated with antibiotic 1 which has an 80% success rate. If this fails (which will happen 20% of the time), then the patient is treated with antibiotic 2 which has a 90% success rate. This 90% will only occur, though, for the remaining 20% of patients who failed the initial treatment. Thus, we calculate this like so: Probability(successful treatment under plan A) = (successful treatment with antibiotic 1) + ((failed treatment with antibiotic 1)*(successful treatment with antibiotic 2)) = 0.8 + (0.2*0.9) = 0.98. Therefore, the probability of successful treatment under plan A equals 98% or 0.98, which corresponds to Choice A.

Step-by-step explanation:

we know that

1 m=3.281 ft

1 mi=5,280 ft

Convert 26 mi to ft

26 mi=26*5,280=137,280 ft

Convert 137,280 ft to m

137,280 ft=137,280/3.281=41,840.90 m

using proportion

9.87/100=x/41,840.90

x=41,840.90*(9.87)/100

x=4,129.70 sec

Remember that

1 hour=3,600 sec

1 hour=60 min

1 min=60 sec

4,129.70 sec=4,129.70/3,600= 1.147 h

John could maintain his 100-m dash pace for an entire 26-mi marathon, his time would be 1 hour, 8 minutes, and approximately 50 seconds.

First, we need to convert John's 100-meter dash time into a pace that can be extrapolated over the marathon distance. Given that John ran a 100-m dash in 9.87 seconds, we need to find out how many meters he runs per second. This would be 100 m / 9.87 s = 10.13 meters per second.

Next, we convert the marathon distance from miles to meters. As there are 5280 feet in a mile and 3.281 feet in a meter, there are 5280 / 3.281 = 1609.34 meters in a mile. The marathon distance is therefore 26 miles * 1609.34 meters/mile = 41842.84 meters.

Using John's pace, we can calculate the time it would take to run the marathon: 41842.84 meters / (10.13 meters/second) = 4129.64 seconds.

Finally, we convert the total seconds to hours, minutes, and seconds. There are 3600 seconds in an hour and 60 seconds in a minute:

Therefore, if John could maintain his 100-m dash pace for an entire 26-mi marathon, his time would be 1 hour, 8 minutes, and approximately 50 seconds.

Step-by-step explanation:

First the easy part... the Y-value.

There's an horizontal line where the P is... that line has a point identified (a,b).  So, the Y-value of P is b.

Now the X-value.  

You see that P is a bit right to c, so it's something more than c, but how much?  If you look, P is as right to C as a is to the origin.  Since we know it's a parallelogram, the line that goes from origin to (a,b) is parallel to the one going from C to P.

So the X-value of point P is: c + a

Probability shows us the chances of an event occurring.

[tex]\bold{Probability =\dfrac{Desired\ Outcome}{Total\ number\ of\ outcomes\ possible}}[/tex]

Now, given that we have already picked three cards. therefore, 7, 8, and 9.

The number of possible outcomes is 3.

[tex]\bold{Probability(7) =\dfrac{Number\ 7(1)}{Total\ number\ of\ outcomes\ possible (3)}= \dfrac{1}{3}}[/tex]

Now, as card seven is already picked up cards 8 and 9 are the only card left.

therefore, the sample size(possible outcomes) was reduced to 2 only.

Also, cards 8 and 9 both are greater than 7, thus the desired outcome is also 2.

Further the probability of the number greater than 7 occurring,

[tex]\bold{Probability(n>7) =\dfrac{cards\ 8\ and\ 9(2)}{Total\ number\ of\ outcomes\ possible (2)}= \dfrac{2}{2} = 1}[/tex]
