Answer:
The coordinates of B will be (3,-4).
Step-by-step explanation:
If a point on the coordinate plane reflects across the y-axis then its y-coordinate will not alter but the x-coordinate will change by its sign only.
Now, if B'(-3,-4) is the image of B after a reflection in the y-axis then we can say B is the image point when the original point is B'(-3,-4) after reflection in the y-axis.
Therefore, the coordinates of B will be (3,-4). (Answer)
Answer:
dependent events since P(A and B) is not equal to P(A) * P(B)
Step-by-step explanation:
According to the Question,
- Given, The probability that Jane will go to a ballgame (event A) on a Monday is 0.73, and the probability that Kate will go to a ballgame (event B) the same day is 0.61. The probability that Kate and Jane both go to the ballgame on Monday is 0.52.
Thus, The events A, B and A∩B are:
A - Jane will go to a ballgame on Monday;
B - Kate will go to a ballgame on Monday;
A∩B - Kate and Jane both go to the ballgame on Monday.
- P(A)=0.73, P(B)=0.61, P(A∩B)=0.52.
- Pr(A)⋅Pr(B) = 0.73⋅0.61 = 0.4453 ≠ 0.52
So, events A and B are dependent events since P(A and B) is not equal to P(A) * P(B)
<u>Answer:</u>
The ratio of African Americans to Hispanics Americans present is 16 : 5
<u>Explanation:</u>
Given the people attending the soccer game were:
2800 among them are Caucasians
4800 are African Americans
1500 are Hispanics
And, 1400 of those were from other ethnic backgrounds
We have to find the Ratio of African Americans to Hispanics Americans
Therefore,
African Americans : Hispanics Americans = 4800 : 1500

Hence, the ratio of African Americans to Hispanics Americans present in the ratio were 16 : 5

Answer:
5. ANOVA for several means
Step-by-step explanation:
In this question, three different means of the data are compared. ANOVA is used for comparing between two or more means to test for differences. It extends the z and t test that are only used for comparing two means.
Since three means are compared, the inference procedure to be used is ANOVA.
