Answer:
-6
Step-by-step explanation:
If the square root of a number is 6, then the number must be 36 (6*6=36)
However, negatives*negatives also equal positives, so
-6*-6 also =36
hence, your answer should be -6
Final answer:
The other square root of a number whose one square root is 6 is -6, because both 6 and -6 squared give the positive number 36.
Explanation:
The question you're asking pertains to finding square roots of a number. Given that one square root of a number is 6, the other square root would also be 6, but with an opposite sign, so it's -6. This is because when either 6 or -6 is squared (multiplied by itself), the result is 36. So, the number you're looking for is 36, and it has two square roots: 6 and -6. This is because the equation x² = √x holds true for both positive and negative values of x that yield the same positive result when squared.
To find the other square root of the number, we need to consider the fact that a positive number has two square roots - one positive and one negative.
Since the given square root is positive and equal to 6, the other square root would be its negative counterpart, which is -6.

How do I solve
[tex] \sin( a ) = .8325[/tex]
It says "Round to the nearest tenth."
Answer:
[tex]a=56.4\degree[/tex]
Step-by-step explanation:
Let [tex]a[/tex] be an acute angle.
To solve: [tex]\sin(a)=0.8325[/tex], we take the sine inverse of both sides to obtain:
[tex]\sin^{-1}(\sin(a))=\sin^{-1}(0.8325)[/tex]
Recall composition property of a function and its inverse function.
[tex]f^{-1}(f(x))=x[/tex]
We apply this property to the left hand side to obtain;
[tex]a=\sin^{-1}(0.8325)[/tex]
We now use our scientific calculator to obtain;
[tex]a=56.3564115\degree[/tex]
We round to the nearest tenth to obtain;
[tex]a=56.4\degree[/tex]
the graph of y= 6cos (x-2) - 3 is obtained by shifting the graph of y=6 cos x-3 horizontally 3 units to the right. true or false?
Answer:
false.
Step-by-step explanation:
Given the function g(x) = f(x − k), can be sketched f(x) shifted k units horizontally. if k is negative, the function is shifted k units to the left.
Given the function g(x) = f(x) + k, we can say that the function is translated vertically upwards k times. If k is negative, the function is translated vertically downwards k times.
In this case, the function is translated two units to the right and 3 units down because the number "-3" is negative.
So it's false. The graph is translated three units downwards and 2 units to the right.
The given statement is a false statement.
Step-by-step explanation:We know that the transformation of the type:
f(x) to f(x+k)
is a horizontal shift of the graph.
The graph is shifted k units to the right if k is negative and if k is positive then the graph is shifted k units to the left.
Here we have the graph as:
[tex]y=6\cos (x)-3[/tex]
and the translated graph is given by:
[tex]y=6\cos (x-2)-3[/tex]
This means that:
f(x) → f(x-2)
i.e. the graph is shifted horizontally 2 units to the right ( since k=2 is positive )

A fresh fruit distributor claims that only 4% of his Macintosh apples are bruised. A buyer for a grocery store chain suspects that the true proportion p is higher than that. She takes a random sample of 30 apples to test the null hypothesis H0: p = 0.04 against the alternative hypothesis Ha: p > 0.04. Which of the following statements about conditions for performing a one-sample z test for the population is correct?
a
We can’t determine if the conditions have been met until we have the sample proportion, p hat .
b
The test cannot be performed because the Random condition has not been met.
c
All conditions for performing the test have been met.
d
The test cannot be performed because the Large Counts condition has not been met.
Final answer:
The correct statement about the conditions for performing a one-sample z test for the population is that we can't determine if the conditions have been met until we have the sample proportion, p hat.
Explanation:
The correct statement about the conditions for performing a one-sample z test for the population is:
a. We can’t determine if the conditions have been met until we have the sample proportion, p hat.
When performing a hypothesis test of a single population proportion, the conditions for a binomial distribution need to be met. These conditions include a certain number of independent trials, success or failure outcomes, and each trial having the same probability of success. In addition, the shape of the binomial distribution should be similar to the shape of a normal distribution, which is ensured when np and nq are both greater than five. Therefore, the conditions cannot be definitively determined until the sample proportion, p hat, is known.
The Large Counts condition is met (np >= 10, n(1-p) >= 10), allowing the z-test. Other conditions are satisfied, validating the test.
Therefore, the correct answer is: **d. The test cannot be performed because the Large Counts condition has not been met.**
To perform a one-sample z-test for the population proportion, we need to check certain conditions:
1. **Random Sample**: The sample should be chosen randomly from the population to ensure that it is representative.
2. **Normality of Population**: There are two criteria for this condition:
- If the population distribution is approximately normal, we can proceed.
- If the population distribution is not normal, the sample size should be large enough (n x p >= 10 and n x (1-p) >= 10) to ensure that the sampling distribution of the sample proportion is approximately normal by the Central Limit Theorem.
3. **Independence**: Each observation in the sample should be independent of the others.
Given:
- Sample size (n) = 30
- Population proportion (p) = 0.04
We need to check if these conditions are met.
a. **We can’t determine if the conditions have been met until we have the sample proportion, p hat.**
- This statement is incorrect because we can still check the conditions without knowing the sample proportion.
b. **The test cannot be performed because the Random condition has not been met.**
- This statement is incorrect because the problem states that the buyer took a random sample of 30 apples, so the Random condition has been met.
c. **All conditions for performing the test have been met.**
- This statement is incorrect because we haven't checked the Large Counts condition yet.
d. **The test cannot be performed because the Large Counts condition has not been met.**
- To check the Large Counts condition, we need to verify whether the sample size is large enough to ensure that the sampling distribution of the sample proportion is approximately normal.
- The Large Counts condition is met if both np >= 10 and n(1-p) >= 10.
- Here, n = 30 and p = 0.04
- np = 30 x 0.04 = 1.2
- n(1-p) = 30 x (1 - 0.04) = 28.8
- Both np and n(1-p) are greater than or equal to 10.
- So, the Large Counts condition is met.
Therefore, the correct answer is: **d. The test cannot be performed because the Large Counts condition has not been met.**

The probability of buying fiction versus nonfiction is the same regardless of
whether or not the person buys a hardcover or paperback in the tree diagram.
Which of the following is true then?
A. The events are dependent on each other.
B. The events are not mutually exclusive
C. The events are independent of one another
D. The events are conditional events
Answer:
C. The events are independent of one another
Step-by-step explanation:
If the probability remains the same whether or not hardcover or paperback is bought, then the probability is not reliant on this variable, and is independent.
The events are independent of one another since the probability of choosing fiction or nonfiction is unaffected by the book format (hardcover or paperback).
The question deals with the concept of probability in the context of buying books, i.e., whether purchasing a fiction or nonfiction book is affected by the format of the book (hardcover or paperback). It is given that the probability of buying fiction versus nonfiction is the same whether or not the person buys a hardcover or paperback.
This implies that the events (buying fiction or nonfiction) are independent of the format. According to the principles of probability, independent events have no impact on each other's occurrence.
The formula for independent events states that P(A AND B) = P(A)P(B), and P(B|A) = P(B).
the game of chance has a spinner with five equal sized sections the results of 625 spins are shown below color orange 118 ,purple 137, Brown 122 ,yellow 106, green 142. for which color is experimental probability closest to the theoretical probability explained
Answer:
Brown.
Step-by-step explanation:
Theoretical probability for each:
625
5
= 125
122 is closest to 125. Therefore Brown has the closest experimental probability to it's theoretical probability.
For brown, the experimental probability is closest to the theoretical probability.
What is the theoretical probability?
We assume that in the ideal case, all the 5 colors have the same probability of being the outcome. Then the probability for each color will be:
P = 1/5 = 0.20
We need to see for which color the experimental probability is closest to 0.20.
The experimental probability will be given by the quotient between the number of times that each color appears and the total number of spins, so we have:
Orange: P = 118/625 = 0.1888Purple: P = 137/625 = 0.2192Brown: P = 122/625 = 0.1952Yellow: P = 106/625 = 1.696Green: P = 142/625 = 0.2272As you can see, the closest one to 0.2 is Brown, so for Brown, the experimental probability is closest to the theoretical probability.

Brad sold candy bars and cookies for a fundraiser at school. Candy bars sold for $3, and cookies sold for $5. He sold a total of 20 items and made $76. How many candy bars did Brad sell? 12 14 16 18]
Answer: First option
12 candy bars were sold
Step-by-step explanation:
Call x the amount of candy sold and call z the amount of cookies sold. Then we know that
[tex]x + z = 20[/tex]
We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76
So:
[tex]3x + 5z = 76[/tex]
To find the quantity of candy bars sold we must solve the system of equations:
[tex]x + z = 20\\\\3x + 5z = 76[/tex]
Multiply the first equation by -5 and add it to the second equation
[tex]-5x -5z = -100[/tex]
+
[tex]3x + 5z = 76[/tex]
--------------------------------
[tex]-2x = -24\\\\x = 12[/tex]
Brad sold 12 candy bars.
To find this answer, you could do the following steps.
1. Use the formula $3b + $5c = $76 where "b" is the number of bars and "c" is the number of cookies.
2. Fill in each of the given answers (12, 14, 16, 18) into "b".
3. Subtract the given answers from 20 to get the number of cookies (8, 6, 4, 2).
4. Solve to see if it comes out even.
Below are all the solutions in which you use these steps.
A. $3 * 12 + $5 * 8 = $76
$36 + $40 = $76
$76 = $76
True
B. $3 * 14 + $5 * 6 = $76
$42 + $30 = $76
$72 = $76
False
C. $3 * 16 + $5 * 4 = $76
$48 + $20 = $76
$68 = $76
False
D. $3 * 18 + $5 * 2 = $76
$54 + $10 = $76
$64 = $76
False
Thus making 12 the answer. I hope this helps!
