Answer:

choice 4

Step-by-step explanation:

It's not that hard if you understand once you get past the fancy words

degree= largest exponent

so if something has a degree of 3 we know that the highest exponent is 3

Coeficcent= thing multipllying x

in this case it's 4 which means the number we are looking for is 4x³

Onlyanswer choice 4 meets these criteria

Answer:

The answer is (4)  \(2x+x^{2} +4x^{3}\).

Step-by-step explanation:

A leading coefficient is the coefficient of the term of highest degree in a given polynomial.  

A degree of a polynomial is the largest exponent on one of its variables (for a single variable), or the largest sum of exponents on variables in a single term (for multiple variables).

The answer can be found when the polynomial is rearranged into standard form, and the standard form of the polynomial will look like \(4x^{3}+x^{2} +2x\). A polynomial is in standard form when the term with the highest degree is placed first, followed by the term which has the next highest degree, and so on.

Once the polynomial is in standard form, the leading coefficient is 4 and has a degree of 3. Thus, causing (4) \(2x+x^{2} +4x^{3}\) to be the answer.

Answer:1/7

Step-by-step explanation: You take the amount that are springer spaniels and you put them with the whole of the dogs in the park 14 so you would have 2/14. You can reduce this fraction to 1/7 by dividing both the top and bottom of the fraction by 2.

Answer: It is a rational number.

Hence, \(2.738\) a rational number.

What is the rationa number?

A rational number is a type of real number, which is in the form of \(\frac{p}{q}\) where \(q\) is not equal to zero. Any fraction with non-zero denominators is a rational number.

Here \(2.73\) acn be written as

\(2.73=\frac{2.73}{1}\)

Now, we multiply numerator and denominator by \(100\).

So, it would be

\(\frac{2.73(100)}{1(100)}\\\\=\frac{273}{100}\)

So, the fraction is written as \(2.73\).

Hence, \(2.738\) a rational number.

Answer:

The mama bear can do it in 9

seconds. The cub can do it in 18

seconds.

Step-by-step explanation:

1/x+9+1/x=1/6

Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.

The together rate is the sum of each separate rate.

In this problem, the rates are as follows:

Given

A tourist ignores the warning signs and leaves food in his car while he goes for a hike.

A mama bear and her cub open the car door in six seconds.

Together with rate: 1/6.

Mama's rate: 1/x.

Cub's rate: 1/(x + 9).

Therefore,

\(\rm \dfrac{1}{x}+\dfrac{1}{x+9}=\dfrac{1}{6}\\\\\dfrac{x+9+x}{x(x+9)}=\dfrac{1}{6}\\\\\dfrac{2x+9}{x(x+9)}=\dfrac{1}{6}\\\\ 6(2x+9)=x(x+9)\\\\12x+54=x^2+9x\\\\x^2+9x-12x-54=0\\\\x^2-3x-54=0\\\\ x^2+6x-9x-54=0\\\\ x(x+6)-9(x+6)\\\\(x-9)(x+6)=0\\\\x-9=0 \ x=9\\\\x+6=0 \ x=-6\)

To maximize the sugar you can gain from street vendors and satisfy your sweet tooth, you can use the following expression:

m[i] = max(m[i-1] + s[i], s[i])

Here, m[i] represents the maximum sugar you can consume so far on the i-th vendor, and s[i] denotes the sugar content of the i-th vendor's offering.

The expression utilizes dynamic programming to calculate the maximum sugar consumption at each step. The variable m[i] stores the maximum sugar you can have up to the i-th vendor.

The expression considers two options: either including the sugar content of the current vendor (s[i]) or starting a new consumption from the current vendor.

To calculate m[i], we compare the sum of the maximum sugar consumption until the previous vendor (m[i-1]) and the sugar content of the current vendor (s[i]) with just the sugar content of the current vendor (s[i]). Taking the maximum of these two options ensures that m[i] stores the highest sugar consumption achieved so far.

By iterating through all the vendors and applying this expression, you can determine the maximum sugar you can gain from the street vendors and satisfy your sweet tooth.

Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.

To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:

SE = sqrt((s1^2 / n1) + (s2^2 / n2))

Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:

SE = sqrt((47^2 / 49) + (4.3^2 / 53))

Next, we calculate the t-statistic using the formula:

t = (x1 - x2) / SE

Where x1 and x2 are the sample means. Plugging in the values, we have:

t = (239 - 21.1) / SE

We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.

In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.

Therefore, the correct answer is:

B. Male and female high school students have different exam scores.

Using the standard normal CDF chart, we can find P(-2/3 ≤ Z ≤ 1), which is approximately 0.6584.

To find the probabilities using the standard normal cumulative distribution function (CDF) chart, we need to standardize the values first.

Given X ~ N(5, 9), we can standardize a value x using the formula:

Z = (x - μ) / σ

where μ is the mean and σ is the standard deviation.

In this case, μ = 5 and σ = √9 = 3.

(a) P(X ≤ 2):

Standardizing 2, we get:

Z = (2 - 5) / 3 = -1

Using the standard normal CDF chart, we can find P(Z ≤ -1), which is approximately 0.1587.

(b) P(X < 3):

Standardizing 3, we get:

Z = (3 - 5) / 3 = -2/3

Using the standard normal CDF chart, we can find P(Z < -2/3), which is approximately 0.2525.

(c) P(X ≥ 3):

This is equivalent to 1 - P(X < 3). Using the result from part (b), we have:

P(X ≥ 3) = 1 - P(X < 3) = 1 - 0.2525 = 0.7475.

(d) P(X > 3):

This is equivalent to 1 - P(X ≤ 3). To find P(X ≤ 3), we can use the result from part (b):

P(X > 3) = 1 - P(X ≤ 3) = 1 - 0.2525 = 0.7475.

(e) P(3 ≤ X ≤ 8):

To find this probability, we need to standardize the values 3 and 8 separately.

For 3:

Z1 = (3 - 5) / 3 = -2/3

For 8:

Z2 = (8 - 5) / 3 = 1

Using the standard normal CDF chart, we can find P(-2/3 ≤ Z ≤ 1), which is approximately 0.6584.

Therefore:

P(3 ≤ X ≤ 8) ≈ 0.6584.

Please note that the values obtained from the standard normal CDF chart are approximations, and for more accurate results, it is recommended to use statistical software or calculators.

The probability that the top two cards drawn from the shuffled deck have the same number is 1/19.

To find the probability that the top two cards drawn from the shuffled deck have the same number, we can calculate the favorable outcomes (same number) and divide it by the total number of possible outcomes.

Calculate the number of favorable outcomes.

Since there are 10 red cards numbered 1-10 and 10 blue cards labeled 1-10, the favorable outcomes occur when we draw two cards of the same number. We have 10 options to choose from (1 to 10), and for each option, we have 2 cards (red and blue).

Therefore, there are a total of 10 × 2 = 20 favorable outcomes.

Calculate the number of possible outcomes.

To determine the total number of possible outcomes, we consider that there are 20 cards in the deck. For the first card drawn, there are 20 options. After the first card is drawn, there are 19 cards remaining for the second draw. So, there are a total of 20 × 19 = 380 possible outcomes.

Calculate the probability.

The probability of drawing two cards with the same number is given by the ratio of the number of favorable outcomes to the number of possible outcomes:

Probability = Favorable outcomes / Possible outcomes

Probability = 20 / 380

Simplifying the fraction, we get:

Probability = 1 / 19

Therefore, the probability that the top two cards drawn from the shuffled deck have the same number is 1/19.

The statement is true.

When the block is in equilibrium, each spring is stretched an additional ∆x. This implies that the forces from the two springs are balanced, and the block is not experiencing any net force in the equilibrium position.

When the block is set into oscillation with amplitude a, it will pass through its equilibrium point during the oscillation. At the equilibrium point, the displacement of the block is zero, and it changes direction. At this point, the block has its maximum speed v, as it is accelerating towards the equilibrium position.

The speed of the block decreases as it moves away from the equilibrium position, reaches zero at the maximum displacement (amplitude), and then starts accelerating towards the equilibrium point again. Therefore, when the block passes through its equilibrium point, it has its maximum speed v.

You can infer causality from a correlational result, but only when the r value is greater than:

C. 1

Causality refers to a situation in which one event causes another. When there is a correlation between two variables, it means that they tend to move in the same direction.

However, this does not necessarily mean that one event causes the other. In order for a correlation to indicate causality, the correlation coefficient (r) must be greater than 1. If the correlation coefficient is below 1, then there is not enough evidence to suggest that one event causes the other.

In addition, there are other factors that need to be considered when assessing causality from a correlational result.

For example, the strength of the relationship between the variables, the direction of the relationship, and the consistency of the results over time. It is also important to consider the context in which the research was conducted, as this may have an effect on the results.
