The equation

\(\frac{24x2+25x-47ax}{-2=8x-3-53}\)

ax−2 is true for all values of x≠

2/a, where a is a constant.

What is the value of a?


A) -16

B) -3

C) 3

D) 16

Answers

Answer 1

Answer:

There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:

24x2+25x−47=(−8x−3)(ax−2)−53

You should then multiply (−8x−3) and (ax−2) using FOIL

("First, Outer, Inner, Last")

24x2+25x−47=−8ax2−3ax+16x+6−53

Then, reduce on the right side of the equation

24x2+25x−47=−8ax2−3ax+16x−47

Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.

The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and I do not recommend it for the actual SAT as it will waste too much time.

soo the final answer is B  -3

The overhead reach distances of adult females are normally distributed with a mean of 205 cm and a standard deviation of 8 cm. Find the probability that the mean for 15 randomly selected distances is greater than 203. 70 cm

Answers

The probability that the mean for 15 randomly selected distances is greater than 203.70 cm is 0.7340 or 73.40%.

Calculation-

The following formula must be used to determine the standard error of the mean (SEM):

SEM equals / sqrt (n)

where n is the sample size and is the population standard deviation.

The SEM is 8 / sqrt(15) = 2.07.

The z-score must then be determined using the following formula:

z = (x - μ) / SEM

where SEM is the standard error of the mean, x is the sample mean, and is the population mean.

z = (203.70 - 205) / 2.07 = -0.63

we need to remove from 1 the likelihood that the mean for 15 randomly chosen distances is greater than 203.70 cm:

P(mean > 203.70) = 1 - P(mean ≤ 203.70)

= 1 - 0.2660

= 0.7340

what fallacy is assuming, without further evidence, that something cause what happened after it?​

Answers

Answer:

Slippery Slope

Explanation:

The Latin phrase "post hoc, ergo propter hoc" means "after this, therefore because of this," and it refers to the fallacy you are discussing. Additionally, it is occasionally referred to as the "post hoc fallacy."

The logical fallacy in a post hoc argument is the assumption that something causes another thing simply because they happen one after the other. The adage "correlation does not imply causation" is frequently used.

When two events occur in close proximity to one another, this is known as correlation. They might be connected, but it could also just be a coincidence.

It is impossible to determine if one led to the other or even if they are indeed connected. This error is frequently made by those who believe that because something occurs after another, it must have a logical cause.

Thus, The Latin phrase "post hoc, ergo propter hoc" means "after this, therefore because of this," and it refers to the fallacy you are discussing. Additionally, it is occasionally referred to as the "post hoc fallacy."

Answer:

Image result for Eight cakes cost 2. 40. How much do 20 cakes cost

How much should I charge for my cake?

First, estimate how many hours is this cake going to take - 5 hours.

Then, calculate the cost of ingredients - $20.

Next, determine the labor cost - $20 x 5 = 100.

Add utility cost - $5.

Sundry cost (small cost) - $5.

Then, calculate the total cost: 20 + 100 + 5 + 5 = $130.

Explanation:

Answer: 20 + 100 + 5 + 5 = $130.

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place

Answers

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Explanation:

If the equation starts with f(-7), then we have to replace the x in the equation to -7.

f(-7) = (-6 (-7) - 2)^2

Next, we multiply -6 and -7 to get a positive 42, since a negative number multiplied by a negative number is a positive number. Then, we subtract 2 from 42 to get 40. Finally, we square 40 by 2 (40 * 40) to get our answer: 1600!

Express this number in scientific notation. 0.000000591

Answers

Answer:

5.91 × 10^-7

Explanation:

Scientific notation is the method of changing a very large or very small number to be a number between 1 and 10 that is multiplied by a power of 10.

For example, the number 0.000000591 can be expressed in scientific notation by following a series of steps.

1.) Count the number of decimal hops that we would need to make so that the number would be between 1 and 10 (5.91 for this question). (in this question, it is 7 decimal places).

2.) After we have the number of hops we need to make the large or small number be between 1 and 10, we determine if the scientific notation is negative or positive. To do this we notice the direction that we hop in step # 1. If we hop from left to right (example 0.000000591) the power of 10 will be negative. If we hop from right to left (example 5,910,000,000) the power of 10 will be positive.

3.) Simply use this formula to find scientific notation:

a = 10^n

a - the given number (0.000000591)

n - the power of ten determined in steps 1 and 2. (-7)

Express this number in scientific notation. 0.000000591

Find the probability of getting 6 or more girls in 8 births.

Answers

Answer:

The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.

Explanation:

Answer:

Explanation:

P(X > 6) = ?

P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)

P(X > 6) = 0.118 + 0.035 + 0.004

P(X > 6) = 0.157

Thus the probability of getting 6 or more girls in 8 births is 0.157
