Answer: 0.31

Step-by-step explanation:

0.3158 is closer too 0.3100 than 0.3000 or 0.3

Rounding 0.3058 to the nearest hundredth gives us 0.31.

Given that a number we need to round it to the nearest hundredth,

To round 0.3058 to the nearest hundredth, we need to look at the digit in the thousandth place (the third decimal place).

Step 1: Look at the digit in the thousandth place. In this case, the digit is 5.

Step 2: Determine if the digit is 5 or greater. If the digit is 5 or greater, we round up. If the digit is less than 5, we round down.

Since the digit in the thousandth place is 5, we round up.

Step 3: Round up the number in the hundredth place. In this case, the number in the hundredth place is 0.

Rounding up 0 to the nearest hundredth gives us 1.

Therefore, rounding 0.3058 to the nearest hundredth gives us 0.31.

Answer:

-94

Step-by-step explanation:

nth term = a₁ + (n-1)d

where a1 = first term , n = number of terms and d = common difference

Here the first term is 80, the number of terms is 30 ( because we want to find the 30th term ) and the common difference is -6

So we have nth term = a₁ + (n-1)d and a₁ = 80 , n = 30 and d = -6

30th term = 80 + (30-1)(-6)

==> subtract 1 from 30

30th term = 80 + (29)(-6)

==> multiply 29 and -6

30th term = 80 + (-174)

==> add 80 and -174

30th term = -94

Note:

The common difference was found by subtracting a term by its the term previous to it. Eg. we have 68, its previous term was 74, so common difference = 68 - 74 = -6. Same with 56 , its previous term is 62, 56 - 62 = -6

According to the Ratio Test, if L > 1, the series diverges. Since L = ∞, the series diverges.

To apply the Ratio Test, we need to find the limit of the ratio of consecutive terms in the series:
\(L = lim (n → ∞) |(aₙ₊₁) / (aₙ)|\)

Given the series Σ (n!) (6n)! aₙ, we can express the terms as:
\(aₙ = (n!) (6n)!aₙ₊₁ = ((n+1)!) (6(n+1))!\)

Now, let's find the limit L:
\(L = lim (n → ∞) |(aₙ₊₁) / (aₙ)|L = lim (n → ∞) |[((n+1)!) (6(n+1))!] / [(n!) (6n)!]|L = lim (n → ∞) |(n+1) (6(n+1))! / (6n)!|L = lim (n → ∞) |(n+1) (6n+6)! / (6n)!|\)

To evaluate this limit, we can simplify the factorials:
(6n+6)! / (6n)! = (6n+6)(6n+5)...(6n+1)

Now the limit becomes:
\(L = lim (n → ∞) |(n+1)(6n+6)(6n+5)...(6n+1)|\)

As n approaches infinity, the limit L will also approach infinity since all the factors in the numerator are increasing with n, and there are no factors in the denominator that can cancel them out. Therefore, L = ∞.

According to the Ratio Test, if L > 1, the series diverges. Since L = ∞, the series diverges.

Answer:

x=5

Step-by-step explanation:

I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.

h(13) - 4 = 339. h(x) is a quadratic function, meaning it has the form\(3x^2\)+ 10. When x is 13, the value of h(x) is 339, so the answer is 339.

h(13) - 4 is the result of subtracting 4 from the value of the function h(x). h(x) is a quadratic function, meaning it has the form\(3x^2 + 10\). Quadratic functions are second-degree polynomials, meaning that the highest exponent of the variable is 2. In this case, the variable is x, and the coefficient of\(x^2 is 3\). This means that for any given value of x, when plugged into the function, the result will be\(3x^2 + 10\). When x is 13, the value of h(x) is \(3(13^2) + 10\), which is 339. Since 4 is being subtracted from this value, the answer to h(13) - 4 is 339.

Step-by-step explanation:

It will take 16hr 30min for Mrs. Smith to catch up.

Let,

t + 3 = Time of Mr. Smith

t = Time of Mrs. Smith

v1 = 55 mph the speed of Mr. Smith

v2 = 65 mph the speed of Mrs. Smith

Formula: Distance = speed × time

v1 ( t + 3)  = v2t

55 ( t + 3 ) = 65t

65t = 55t + 165

65t - 55t = 165

10t = 165

t = 16.5 hr

t = 16 hr 0.5 × 60 min

Given the following functions:

f(x)=4x−6

g(x)=x+2

To find:

(f⋅g)(x) and (f−g)(x) and evaluate

(f+g)(−2).(f⋅g)(x) = f(x) × g(x)

= (4x−6) × (x+2)

We get, (f⋅g)(x) = 4x² - 2x - 12

(f−g)(x) = f(x) - g(x)

= (4x−6) - (x+2)

= 3x - 8

(f+g)(-2) = f(-2) + g(-2)

= 4(-2) - 6 + (-2) + 2

= -8+0

= -8

Therefore,

(f⋅g)(x) = 4x² - 2x - 12

(f−g)(x) = 3x - 8

(f+g)(-2) = -8

Conclusion: The expressions for (f⋅g)(x) and (f−g)(x) are 4x² - 2x - 12 and 3x - 8 respectively. The value of (f+g)(−2) is -8.

Answer:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years

Step-by-step explanation:

Let us represent:

The age of the youngest child = x

The age of middle child = y

The age of the oldest child = z

The sum of the ages of the children is 26.

Hence: x + y + z = 26...... Equation 1

The oldest is 4 years older than the middle

z = 4 + y

The youngest child is 2 years younger than the middle child

x = y - 2

Hence, we substitute 4 + y for z and y - 2 for x in Equation 1

x + y + z = 26...... Equation 1

y - 2 + y + 4 + y = 26

y + y + y -2 +4 = 26

3y + 2 = 26

Subtract 2 from both sides

3y + 2 - 2 = 26 - 2

3y = 26 - 2

3y = 24

y = 24/3

y = 8

Solving for x

x = y - 2

x = 8 - 2

x = 6

Solving for z

z = 4 + y

z = 4 + 8

z = 12

Therefore:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years

This criterion can be defined based on the desired level of accuracy or when the change in the estimated parameters falls below a certain threshold.

When implementing a program for a nonlinear problem using the least square adjustment technique, it is essential to determine a termination condition. This condition dictates when the program should stop iterating and provide the final estimated parameters. A common approach is to set a convergence criterion, which measures the change in the estimated parameters between iterations.

One possible criterion is to check if the change in the estimated parameters falls below a predetermined threshold. This implies that the adjustment process has reached a point where further iterations yield minimal improvements. The threshold value can be defined based on the desired level of accuracy or the specific requirements of the problem at hand.

Alternatively, convergence can also be determined based on the objective function. If the objective function decreases below a certain tolerance or stabilizes within a defined range, it can indicate that the solution has converged.

Considering the chosen termination condition is crucial to ensure that the program terminates effectively and efficiently, providing reliable results for the nonlinear problem.

Answer:

\(\huge\boxed{\text{(A)}\ 0.36}\)

Step-by-step explanation:

This sequence will have a pattern. Our goal is to try and find this pattern.

Our first two numbers are -45 and 9. The first relationship between these numbers that pops into my mind is 5. \(9 \cdot 5 = 45\). However, we go from -45 to 9. This means we have to divide by -5. \(-45 \div -5 = 9\)

Let's check this actually is what the sequence is. It would be true if \(9 \div -5 = -1.8\).

\(9 \div -5 = -1.8\)

So -5 is the divisor.

To find the next term in the sequence, we divide -1.8 by -5.

\(-1.8 \div -5 = 0.36\)

The measurement that is closest to the value of x, in centimeters, is given as follows:

14.3.

In this problem, we have a right triangle, in which the legs, which are the sides between the angle of 90º, are of 11.9 cm and 7.9 cm.

Then the hypotenuse x, which is the segment connecting both legs, is obtained using the Pythagorean Theorem.

The Pythagorean Theorem states that the measure of the hypotenuse squared is equals to the sum of the squares of the measures of each side.

Then the length of x is calculated as follows:

x² = 11.9² + 7.9²

x = square root of (11.9² + 7.9²)

x = 14.28.

Closest to 14.3, rounding to the nearest tenth, meaning that the third option is correct.

Answer:

Step-by-step explanation:

Draw a line through the data points with about half of the points on one side of the line and the other half on the other side.  You'll see that there is a slight positive rise in the graph as we move from left to right, but the correlation is weak.  Thus, 0.4 is the correct correlation coefficient in this case.

The correlation coefficient that would best describe the data give in the table is 0.4 which is a weak positive correlation.

The statistical concept of correlation describes how closely two variables move in tandem with one another.

As the graph is scattered in such a way that,if we draw a line from the centre, we can observe that as 'x' increases 'y' also increases so the relation is positive correlation.

But it is seen in the graph that these points are scattered, so this relation is weak. For positive weak correlation the value should be less than 0.5.

Therefore, the given graph shows positive weak correlation with value 0.4.

The expected time for activities, use the formula for expected value and multiply the time for each activity by its probability. Therefore, the expected time for these activities is 2.8 hours.

To calculate the expected time for activities, we can use the formula for expected value.

The expected value is calculated by multiplying the time for each activity by its probability of occurrence, and then summing up these values. The formula for expected value is: Expected Value = (Time1 * Probability1) + (Time2 * Probability2) + ... + (TimeN * ProbabilityN) Here's a step-by-step example:

1. List all the activities and their corresponding times and probabilities.

2. Multiply the time for each activity by its probability.

3. Sum up the values obtained in step 2.

For example, let's say we have two activities: Activity 1: Time = 2 hours, Probability = 0.6 Activity 2: Time = 4 hours, Probability = 0.4 Using the formula, we calculate the expected time as follows: Expected Time = (2 hours * 0.6) + (4 hours * 0.4) = 1.2 hours + 1.6 hours = 2.8 hours

Therefore, the expected time for these activities is 2.8 hours.

Here full question is not provided  but the full answer given above.

Remember, this is just one example, and you can use the same formula for any number of activities with their respective times and probabilities. In summary, to calculate the expected time for activities, use the formula for expected value and multiply the time for each activity by its probability.
