The options are A. 7/3x4/5 B. 7/3x5/4 C. 3/7x4/5 D.3/7x5/4

In baseball, a player pitches a ball from the mound to a catcher behind the plate. A pitch that passes over the plate above the

matrenka [14]

To solve this question, you just need to count all the probability of the options.

The probability that a pitch not over the plate is a strike is zero. So, P(A | D) = 0.

True. It is 0/0+20= 0

The probability that a pitch not over the plate is a ball is 1. So, P(B | D) = 1.

True, it is 20/20+0= 1

The probability that a pitch over the plate is a strike is 10:15. So, ...

Incomplete but it sounds to be true. It should be 10/10+5= 10/15 = 2/3

The probability that a pitch over the plate is a ball is 5:10. So, P(B | C) = 0.5.

Ian puts 300.00 into an account to use for school expenses the account earns 6%interest compounded annually how much will be in

romanna [79]

This problem is about componded interest. The formula for compounded interest is:

$\begin{gathered} \text{Amount}=\text{Initial}\cdot(1+r)^t \\ \text{Where,} \\ \text{Amount is the total acumulative at time t.} \\ \text{Initial is the initial amount, at t=0} \\ r\text{ is the interest in decimal number.} \\ t\text{ is the time accordingly the interest, in this case is in years.} \end{gathered}$

In this case, Initial = 300, r = 0.06 and t=10 so the total amount in the account after 10 years is:

$\begin{gathered} \text{Amount}=300\cdot(1+0.06)^{10} \\ \text{Amount}=300\cdot1.06^{10} \\ \text{Amount}=300\cdot1.79085 \\ \text{Amount}=537.255 \end{gathered}$

The amount after 10 years is 573.26.

Which of the following represents the mean absolute deviation of Jamal’s data?

Gnesinka [82]

Answer:

1.178

Step-by-step explanation:

(for Jamal)

5 x 2 = 10

6 x 3 = 18

7 x 2 = 14

8 x 1 = 8

10 x 1 = 10

Mean: 10 + 18 + 14 + 8 + 10 = 60/9 = 6.6

6.6 - 5 = 1.6 x 2 = 3.2

6.6 - 6 = 0.6 x 3 = 1.8

7 - 6.6 = 0.4 x 2 = 0.8

8 - 6.6 = 1.4

10 - 6.6 = 3.4

Mean Absolute Deviation: 3.2 + 1.8 + 0.8 + 1.4 + 3.4 = 10.6/9 = 1.178
