Answer:

The value is  \(P(X > 3.30) = 0.12405\)

Step-by-step explanation:

From the question we are told that

   The mean GPA is  \(\mu = 3.25\)

   The standard deviation is \(\sigma = 0.75\)

    The sample size is  n  =  300

Generally the standard error of mean is mathematically represented as

     \(\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }\)

=>   \(\sigma_{\= x} = \frac{0.75}{\sqrt{300} }\)

=>   \(\sigma_{\= x} = 0.0433\)

Generally the  probability that a random sample of 300 students will have a mean GPA greater than 3.30 is mathematically represented as

     \(P(X > 3.30) = P(\frac{X - \mu}{\sigma_{\= x}} > \frac{3.30 -3.25}{ 0.0433} )\)

\(\frac{\= X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ \= X )\)

    \(P(X > 3.30) = P(Z> 1.155 )\)

From the z table the probability of  (Z >  1.155 ) is

     \(P(Z> 1.155 ) = 0.12405\)

   \(P(X > 3.30) = 0.12405\)

Step-by-step explanation:

To determine the value of x that satisfies the expression x^2 + 3x - 5 when x = 9, we simply substitute 9 for x and evaluate the expression:

9^2 + 3(9) - 5 = 81 + 27 - 5 = 103

Therefore, when x = 9, the expression x^2 + 3x - 5 evaluates to 103.

The rental cost in dollars per square foot is $11,00

Cost of renting 1.250 square feet = $13, 750 per month

Rental cost per square foot = Total renting cost / total renting area

= $13, 750 per month / 1.250 square feet

= $11,000

Hence, $11,000 is the rental cost in dollars per square foot.

T = 2*PI* sq root (L / g)

Squaring both sides

The fastest speed a table-tenis ball is 69.92.

According to the statement

we have to find that the fastest speed of a table-tennis ball with the given information.

For this purpose, we know that the

Speed is the rate at which someone or something is able to move.

From the give information:

The fastest speed a table-tenis ball has been hit is about 13.07 times as fast as the fastest swimming speed which is 5.35.

Now, the speed of the fastest swimming is 5.35

And

the speed of the table-tenis ball has been hit is about 13.07 times as fast as the fastest swimming speed

The equation become

5.35(13.07)

Then

fastest speed a table-tenis ball = 5.35(13.07)

Answer: so dog goes to cat, dog goes to rabbit and cat goes to rabbit I think

Step-by-step explanation:

The possible Subset is

Sub sets :  {dog}, {cat}, {fish}, {dog, cat}, {dog, fish}, {cat, fish}, {dog, cat, fish}.

If each constituent of a set A is a member of a different set B, then the sets A and B are subsets of one another.

To put it another way, A⊂B A and B stand for the subset connection.

Set A is referred to as a subset of Set B if all of the elements in Set A are also found in Set B. In other words, Set A is a part of Set B. A is the subset of B, for instance, if set A contains the elements X, Y, and set B contains the elements X, Y, and Z.

We have set,

Set :  {dog, cat, fish}

Then, the subset contain the elements of set A as

We observe that the sequence is decreasing with common difference of - 3.

Therefore, this is an AP, with the first term of t(1) = 13 and common difference of d = -3.

Use the nth term formula for AP:

Answer:

a)  Arithmetic sequence

b)  t(n) = 16 - 3n

Step-by-step explanation:

An Arithmetic Sequence has a constant difference between each consecutive term.

A Geometric Sequence has a constant ratio (multiplier) between each consecutive term.

From inspection of the given table, t(n) decreases by 3 each time n increases by 1.  Therefore, the sequence is arithmetic with a common difference of -3.

\(\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}\)

Given:

Substitute the initial value (when n = 1) and the common difference into the formula to create an equation for the nth term:

\(\implies t(n)=13+(n-1)(-3)\)

\(\implies t(n)=13-3n+3\)

\(\implies t(n)=16-3n\)

To find a and minus one a, we need to factorize the equation -2a^2 - a + 1 = 0.

First, we can simplify the equation by multiplying both sides by -1, so we have:

2a^2 + a - 1 = 0

Next, we can use the quadratic formula to solve for a:

a = (-b ± √(b^2 - 4ac)) / 2a

Plugging in the values for our equation, we have:

a = (-1 ± √(1^2 - 4(2)(-1))) / 2(2)

Simplifying this equation, we get:

a = (-1 ± √9) / 4

a = (-1 ± 3) / 4 Therefore, we get two possible values for a: a = -1/2 or a = 1/2

Now, we can use these values to find minus one a: If a = -1/2, then minus one a = -2/2 = -1 If a = 1/2,

then minus one a = 3/2 = 1Therefore, a can't be either -1/2 or 1/2.

Step-by-step explanation:

To find a and minus one a, we need to factorize the equation -2a^2 - a + 1 = 0.

First, we can simplify the equation by multiplying both sides by -1, so we have:

2a^2 + a - 1 = 0

Plugging in the values for our equation, we have:

a = (-1 ± √(1^2 - 4(2)(-1))) / 2(2)

Simplifying this equation, we get:

a = (-1 ± √9) / 4

a = (-1 ± 3) / 4 Therefore, we get two possible values for a: a = -1/2 or a = 1/2

Now, we can use these values to find minus one a: If a = -1/2, then minus one a = -2/2 = -1 If a = 1/2,

then minus one a = 3/2 = 1Therefore, a can't be either -1/2 or 1/2.

A) Because the point lies outside the linear trend, it weakens the correlation. The intensity and direction of the link between two variables are measured by their correlation.

The scatterplot's points may be used as a visual representation of the link between the two variables and as a tool for assessing the correlation's strength.

The correlation is said to be high if a scatterplot's points show a distinct and recurrent pattern, such as a linear trend. The association is weak, though, if the points are dispersed and don't create a distinct pattern. In scatterplot, outliers can have a large impact on the correlation because they can cause the linear trend to be distorted

Answer:

Engineer: 9.5 hr

Assistant: 4.5 hr

Step-by-step explanation:

To solve this problem, we can create and solve a system of equations.

Define the variables:

Given the engineer's time is billed at $40 per hour, and her assistant's is billed at $10 per hour, and a customer received a bill for $425 for a certain job:

Given the assistant worked 5 hours less than the engineer:

Therefore, the system of equations that represents the problem is:

\(\begin{cases}40x+10y=425\\ \quad \qquad \;\;\;y=x-5\end{cases}\)

Substitute the second equation into the first equation to eliminate y:

\(40x+10(x-5)=425\)

Solve the equation for x to find the number of hours the engineer worked:

\(\begin{aligned}40x+10(x-5)&=425\\40x+10x-50&=425\\50x-50&=425\\50x&=475\\x&=9.5\end{aligned}\)

Therefore, the engineer worked 9.5 hours.

Substitute the found value of x into the second equation and solve for y to find the number of hours the assistant worked:

\(\begin{aligned}y&=x-5\\y&=9.5-5\\y&=4.5\end{aligned}\)

Therefore, the assistant worked 4.5 hours.

Answer:

\(w=15.5\)

\(w=\frac{31}{2}\)

Equation:

\(2w+4=35\)

Step-by-step explanation:

\(2w+4=35\\2w=31\\w=15.5\)

Hidden Steps:

1) Subtract 4 on each side of the equation:

\(2w+4-4=21\\35-4=31\)

2) Divide each side of the equation by 2:

\(2w\) ÷ \(2=w\)

\(31\) ÷ \(2=15.5-or-\frac{31}{2}\)

Answer:

Equation: 2w + 4 = 35

Weight: 15.5

Step-by-step explanation:

Let w be the weight of each checked bag.

The weight of Carl's 2 checked bags is 2w kg. The weight of his backpack is 4kg. The total weight of his baggage is 2w + 4 kg.

Since his total baggage weighs 35 kg, let us set this to 35:

2w + 4 = 35

Now you solve:

1. 2w + 4 = 35

2. 2w = 35-4

3. 2w = 31

4. w = 31/2

5. w = 15.5

Therefore, the equation is 2w + 4 = 35 and the solution to " w " is 15.5 kg.

Hopefully this helps you understand more!
