Supposing the value of x to be an integer, the values of k that donot

satisfy the given equation 3x = k mod 6 are 1,2,4,5.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.

Integers are a set of numbers that include both positive and negative numbers, as well as zero. Whole numbers, on the other hand, only include the set of non-negative numbers starting from 0 (i.e., 0, 1, 2, 3, 4, ...). In other words, whole numbers are a subset of integers.

If 3x = k mod 6 has no solutions in x, then k must not be divisible by 3. The positive integers less than 6 that are not divisible by 3 are 1, 2, 4, and 5. Therefore, k can take on 4 values: 1, 2, 4, and 5.

Using a standard normal distribution table, we can find that the percentage of values below a z-score of -1.6 is approximately 5.0%. Therefore, we can say that Carl has a higher GPA than approximately 95% of other students at UTA.

To determine Carl's z-score, we need to know the mean and standard deviation of GPAs at UTA. Without this information, we cannot calculate the z-score. However, we can still determine the percentage of other students at UTA who have a lower GPA than Carl. We can use a standard normal distribution table to find this percentage, assuming that GPAs at UTA are approximately normally distributed.

First, we need to calculate the z-score corresponding to Carl's GPA of 2.2. Assuming a mean GPA of 3.0 and a standard deviation of 0.5, we can use the formula: z = (x - μ) / σ

where x is Carl's GPA, μ is the mean GPA, and σ is the standard deviation. Plugging in the values, we get:

z = (2.2 - 3.0) / 0.5 = -1.6

Using a standard normal distribution table, we can find that the percentage of values below a z-score of -1.6 is approximately 5.0%. Therefore, we can say that Carl has a higher GPA than approximately 95% of other students at UTA.

Answer:

14.940306992% or 15%

Step-by-step explanation:

To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.

$ 175.90 - $ 149.62 = $26.28

Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.

$26.28 / $175.90

= 0.14940306992

Finally, multiply by 100 and round up to reach a percentage.

Annalise is correct because the outputs are closest when x = 1.35

Step-by-step explanation:

The solution to the equation 1/(x-1) = x² + 1 means the one x value that will make both sides equal. If we look at the table, notice how when x = 1.35, f(x) values are closest to each other for both equations, signifying that x = 1.35 is approximately the solution. Thus, Annalise is correct.

Answer:

276 individuals at the party.

Step-by-step explanation:

If 6 of your friends are couples then we would count them as 1 each and it would be 3 friends. Therefore we subtract 3 from your 58 friends.

58 - 3 = 55 friends

Each of them brings 5 friends so we multiply your number of friends by 5.

55 * 5 = 275 friends

Finally, we add you because you are included

275 + 1 = 276

There will be a total of 276 individuals at the party.

Step-by-step explanation:

The amount of added sugar in coca-cola is 16.5 tsp

The amount of added sugar in pepsi is 17.5 tsp

Since the combination of 20 fl oz of Coca Cola and 20 fl oz of Pepsi contain 34 tsp of added sugar.

Let c represents the quantity of sugar in 20 fl of coca-cola

Let p represents the quantity of sugar in 20 fl oz of Pepsi

The addition of both quantities equal 34 tsp

Mathematically,

c + p = 34...............(1)

The coca-cola contains 1 tsp less of added sugar than the pepsi:

Expressing this mathematically,

c = p - 1.................(2)

Substitute equation (2) into equation (1)

p - 1 + p = 34

2p = 34 + 1

2p = 35

p = 35/2

p = 17.5

Substitute the value of p into equation (2):

c = p - 1

c = 17.5 - 1

c = 16.5

The amount of added sugar in coca-cola is 16.5 tsp

The amount of added sugar in pepsi is 17.5 tsp

Answer:

Customary Units

Step-by-step explanation:

United States customary units are a system of measurements commonly used in the United States since it was formalized in 1832

To express the function F(x) = (x - 3)² in the form fog, we need to find two functions, f(x) and g(x), such that F(x) = (f ∘ g)(x).

Let's start by expanding F(x):

F(x) = (x - 3)²

= (x - 3)(x - 3)

= x² - 6x + 9

Now, let's express F(x) in terms of f(g(x)):

F(x) = (f ∘ g)(x)

Comparing the expanded form of F(x) with the expression for (f ∘ g)(x), we can deduce that:

f(x) = x²

g(x) = x - 3

So, we can express F(x) = (x - 3)² in the form fog as:

F(x) = (f ∘ g)(x) = f(g(x)) = (g(x))²

= (x - 3)²

Therefore, f(x) = x² and g(x) = x - 3 form the composition f ∘ g such that F(x) can be expressed as (f ∘ g)(x).

The 90% confidence interval for the difference in the population means is -2.51 to 0.31

From the question, we have the following parameters that can be used in our computation:

xˉ₁ = −17.1

s₁² = 8.4

n₁ = 22

​xˉ₂ = −16.0

s₂² = 8.7

n₂ = 24

Calculate the pooled variance using

P = (df₁ * s₁² + df₂ * s₂²)/df

Where

df₁ = 22 - 1 = 21

df₂ = 24 - 1 = 23

df = 22 + 24 - 2 = 44

So, we have

P = (21 * 8.4 + 23 * 8.7)/44

P = 8.56

Also, we have the standard error to be

SE = √(P/n₁ + P/n₂)

So, we have

SE = √(8.56/22 + 8.56/24)

SE = 0.86

The z score at 90% CI is 1.645, and the CI is calculated as

CI =  (x₁ - x₂) ± z * SE

So, we have

CI = (-17.1 + 16.0) ± 1.645 * 0.86

This gives

CI = -1.1 ± 1.41

Expand and evaluate

CI = (-2.51, 0.31)

Hence, the confidence interval is -2.51 to 0.31

Step-by-step explanation:

The amount of money that Alonso has invested in these accounts is given as $9000 and $21000

We have to represent the percentages as a and b, then multiply 100 at the right hand side of the equation

we would have

7a + 5b = 1680 * 100

7a + 5b = 168000 ---- 1

From the amount that Alonso has to invest we would have

a + b = 30000

where b = 30000 - a   ---- 2

We have to put the value of b in equation a

7a + 5(30000 - a) = 168000

7a + 150000 -5a = 168000

7a - 5a = 168000 - 150000

2a = 18000

a = 18000 / 2

= $9000

Answer: we can form an Isosceles triangle using the given measures.

An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0

Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.

There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.

We will find the slope using the slope formula that is

⇒ m  = (y₂ - y₁)/(x₂ - x₁)

Given points are (-5, 3) and (2, 1), so

⇒ m  = (1 - 3)/(2 - (-5))        

⇒ m  = -2/7

We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).​

for a two lines to be parallel, m = m for both lines

so as the slope is (-2/7), lets put the value in (0,0)

y = mx + b

0 = (-2/7)0 + b

b = 0

And therefore the equation is 0 = (-2/7)0 + 0

The possible data in the question does not provide sufficient evidence available to support the alternative hypothesis that there is a difference between Mr. Starnes and Ms. McGrail's AP Statistics classes and Mr. Starnes did not stack the class.

In statistics, a hypothesis test is the performance of a test on an assumption made about a population parameter.

The possible data in the question, obtained from a similar online question, using MS Excel, indicates;

The mean of the Starnes GPA ≈ 3.212867

The standard deviation of Starnes GPA ≈ 0.364249

Mean of McGrail GPA ≈ 3.134722

The standard deviation of McGrail's GPA ≈ 0.357995

The null hypothesis is H₀: μ₁ - μ₂ = 0

The alternative hypothesis is Hₐ: μ₁ - μ₂ ≠ 0

The test statistic is found using the following formula;

\(t_0 = \dfrac{(\overline{x_1} - \overline{x_2})-(\overline{\mu_1}-\overline{\mu_2})}{\sqrt{\dfrac{s_1^2}{n_1}+\dfrac{s_2^2}{n_2} } }\)

The decision rule is obtained with α = 0.05 and the null hypothesis is rejected t₀ ≤ -1.96 or t₀ ≥ 1.96

Therefore, we get;

\(t_0 = \dfrac{(3.212867 - 3.134722)-0}{\sqrt{\dfrac{0.364249^2}{15}+\dfrac{0.357995^2}{18} } } \approx 0.618\)

The parameter for the degrees of freedom is 15 - 1 = 14

The critical value obtained from the t-table, at t.₉₅ is 1.761 which is larger than 0.618, therefore, we fail to reject the null hypothesis, and the evidence is insufficient to suggest that there is a difference in the average score of the two AP Statistics classes.

Taking the variance to be the same, we get;

\(S_p^2= \dfrac{(n_1-1)\cdot s_1^2+(n_2-1)\cdot s_2^2}{n_1+n_2-2}\)

Therefore;

\(S_p^2= \dfrac{(15-1)\times 0.364249^2+(18-1)\times 0.357995^2}{15+18-2}\approx 0.1302\)

\(t_0 = \dfrac{(\overline{x_1} - \overline{x_2})-(\overline{\mu_1}-\overline{\mu_2})}{\sqrt{s_p^2 \times\left(\dfrac{1}{n_1}+\dfrac{1}{n_2} }\right) }\)

\(t_0 = \dfrac{(3.212867 - 3.134722)-0}{\sqrt{0.1302\times \left(\dfrac{1}{15}+\dfrac{1}{18} }\right) } \approx 0.6195\)

df = 15 + 18 - 2 = 31

From the t-table, the critical value is about 1.697, which is larger than 0.6195, therefore, the null hypothesis cannot be rejected and the evidence available is not enough to suggest that there is a difference between the grade point averages of Mr. Starnes and Ms. McGrail AP Statistics classes and Mr. Starnes did not stack the class
