A distribution is positively skewed if which of these statements is true about the density curve that represents it?A. The left side is a mirror reflection of the right side.
B. The left tail is equal in length to the right tail.
C. The left tail is longer than the right.
D. The right tail is longer than the left.

Answers

Answer 1

Answer: The right answer for the question that is being asked and shown above is that: "D. The right tail is longer than the left." Positively skewed distribution is asymmetrical and points in the positive direction. So, the tail on the right is longer than that of the left.

Alicia drove at a constant speed and traveled 183 miles in 3 hours. How many miles would Alicia travel in 11 hours at the same speed?

Answers

Answer:

671 miles.

Step-by-step explanation:

We have been given that Alicia drove at a constant speed and traveled 183 miles in 3 hours.

First of all, we will Alicia's speed using speed formula.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Alicia's speed}=\frac{\text{183 miles}}{\text{3 hours}}$

$\text{Alicia's speed}=\frac{\text{61 miles}}{\text{ hour}}$

So Alicia's travels at a speed of 61 miles per hour.

To find distance covered by Alicia is 11 hours, we will multiply per hour speed by 11 as:

$\text{Distance covered by Alicia is 11 hours}=\frac{\text{61 miles}}{\text{ hour}}* \text{11 hours}$

$\text{Distance covered by Alicia is 11 hours}=\text{61 miles}* 11$

$\text{Distance covered by Alicia is 11 hours}=\text{671 miles}$

Therefore, Alicia will travel 671 miles in 11 hours.

Answer:

Step-by-step explanation: 3 hours = 183 miles that means 1 hour = 61 miles so 11 hours is 61 multiplied by 11 which is = 671 miles... ✌️

In a softball game, the odds are only win or lose the game. When 2 games are already being considered, the elements in the sample space are already 2 in each set. The sets are {W,W}, {W,L}, {L,W} and {L,L}. Hence, there are 4 sets all in all to describe the odds of the two games.

According to the Fundamental Theorem of Algebra, how many roots exist for the polynomial function?(9x + 7)(4x + 1)(3x + 4) = 0

Answers

Answer:

Three roots exist of given polynomial.

Step-by-step explanation:

Given: $(9x+7)(4x+1)(3x+4)=0$

Fundamental theorem of algebra: It states that each factor of polynomial with complex coefficient must be atleast one complex root.

If polynomial with real coefficients then their complex root with zero imaginary part.

In the given polynomial, $(9x+7)(4x+1)(3x+4)=0$

Each term as factor factor. Here we have total three factor. If we set each factor to 0 and solve for x. We will get root for each value of x.

So, Here should be three roots possible.

$9x+7=0\Rightarrow x=-(7)/(9)$

$4x+1=0\Rightarrow x=-(1)/(4)$

$3x+4=0\Rightarrow x=-(4)/(3)$

All roots are real.

Hence, Three roots exist of given polynomial.
