Answer:

The scatter plot has both outliers and clusters.

Step-by-step explanation:

We are given the following information in the question.

The scatter plot shows:

  • A scatter plot is a two-dimensional data visualization technique.
  • Dots are used to represent the values obtained for two different variables.

The x-axis shows the number of blackbirds seen and y-axis shows the number of Robins seen.

Yes, there is an outlier in the scatter plot. It could be easily seen as it lies totally away from all the points of the scatter plot. It has a different model or representation that all the other data set.

Yes, we can see clusters in the scatter plot. three clusters can be easily identified in the scatter plot.

Clusters are basically a collection of data points from the data set that are very close to each other and show similar properties. They from distinct groups in the data set.

I think your answer is correct if not the last one because there is an outlier and with process of elimination all the others ones that say there isn't are incorrect and unless that answer you have bubbled is incorrect than your last resort is the One cluster One outlier but i honestly dont see a true cluster :)

Fidel has a rare coin worth \$550$550dollar sign, 550. Each decade, the coin's value increases by 10\%10%10, percent.
FinnZ [79.3K]

Answer:

Option B - 550(1+0.1)^6

Step-by-step explanation:

Given : Fidel has a rare coin worth $550. Each decade, the coin's value increases by 10%.

To find : Which expression gives the coin's value, 6 decades from now?

Solution :

The given situation represents the exponential function,

y=a(1+r)^n

where, a is the initial value i.e. a=$550

r is the increased rate r=10%

n is the time i.e. n=6

Substitute the value in the formula,

y=550(1+10\%)^6

y=550(1+0.1)^6

Therefore, option B is correct.

A jar contains 8 red marbles and y white marbles. If Joan takes 2 random marbles from the jar, is it more likely that she will h
podryga [215]

Answer:

a) y </= 8 is not sufficient

b) y >/= 4 is sufficient (y is not less than 3.5)

Step-by-step explanation:

Number of Red marbles = 8

Number of white marbles = y

Total number of marbles in the jar = 8+ y

Let Pr(R) be the probability of picking red marbles

Let Pr(W) be the probability picking white marbles

Pr(R) = 8/ (8+y)

Pr(W) = 7/(7+y)

Pr(RR) = Pr(R1) * Pr( R2)

= 8/(8+y) * 7/(7+y)

Pr(RW) = Pr(R1) * Pr(W2) + Pr(W1) * Pr(R2)

= 2[Pr(R1) * Pr(W2)

= 2[8/(8+y) * y/(7+y)]

The probability of having 2 red is greater than one marble of each color.

Pr(RR) > Pr( RW)

8/(8+y) * 7/(7+y) > 2[8/(8+y) * y/(7+y)]

7/(7+y) > 2(y/(7+y)

7/y > 2

7/2 > y

3.5 > y

y < 3.5

Therefore;

a) y </= 8 is not sufficient

b) y >/= 4 is sufficient (y is not less than 3.5)

Determine whether the binomial is a factor of f(x).<br><br> f(x) = x3 + 11x2 + 24x - 36; x - 4
attashe74 [19]
If it is, then f(4) would be equal 0.

f(4)=4^3+11\cdot4^2+24\cdot4-36\\&#10;f(4)=64+11\cdot16+96-36\\&#10;f(4)=124+176\\&#10;f(4)=300\not =0 \Rightarrow \text{ it isn't}
