A total of 600 of the 1,000 people living in a retirement community classify themselves as Republicans, while the others classif

zheka24 [161]

Answer:

0.0847 = 8.47%

Step-by-step explanation:

Since 600 people are classified as Republicans, 400 people are classified as Democrats.

It can be calculated the number of people who voted for each party as follows:

Votes for Republicans = 600 (total Republicans) – 60 (Republicans who voted for the Democratic candidate) + 50 (Democrats who voted for the Republican candidate) = 590 votes

Votes for Democrats = 400 (total Democrats) – 50 (Democrats who voted for the Republican candidate) + 60 (Republicans who voted for the Democratic candidate) = 410 votes

A total of 590 people voted for the Republicans and 50 of those are Democrats. Thus, the probability that a person who voted for The Republican candidate is a Democrat can be calulated:

P = 50/590 = 0.0847 = 8.47%

yaroslaw [1]

<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Pythagoras' theorem:

b^2 = c^2 - a^2

Substitute in the values:

b^2 = 13^2 - 12^2

b^2 = 25

Square root it

b = 5km

The answer is option B. 5km

Suppose there are 6 runners in the finals of a 100 m sprint, Abbie, Becca, Clarice, Danna, Emma, and Francine. Answer each of th

riadik2000 [5.3K]

Step-by-step explanation:

1. Abbie's chance to place first is 12÷100 = 0.12 $12÷100 = 0.12$

and Becca's chance to place second is 8÷100= 0.08 $8÷100= 0.08$

We can determine the probability that Abbie will place first and Becca will place second because ., Abbie gets more chance than Becca (0.12 -0.08 =0.04) to get first place

2. Danna's chance to place first is P(A) = 48÷100 = 0.48 $48÷100 = 0.48$

Francine's chance to place second is P(B) = 32 ÷100 = 0.38 $32 ÷100 = 0.38$

The probability that Danna or Francine wins the race is

= P(A or B) = P(A) +P(B) - P(A and B)

= 0.48 +0.32 - (0.48× 0.32) $0.48 +0.32 - (0.48× 0.32)$

= 0.8 - 0.15 = 0.65 $0.8 - 0.15 = 0.65$

3. Yes .,that Grace's probabilities were wrong Because Grace only informs about the winning chance of Abbie, Becca ,Danna,and Francine.

Grace gives 12% to Abbie and 48% to Danna ., in real Abbie won the first place ., so ., Grace's probabilities were wrong
