Answer : The percentage will be, 200%

Step-by-step explanation :

First we have to calculate the excess weight.

Excess weight = 45 kg - 15 kg

Excess weight = 30 kg

Now we have to calculate the percentage of excess weight.

Percentage of excess weight = $\frac{\text{Excess weight}}{\text{Weight of Jake's}}\times 100$

Percentage of excess weight = $\frac{30kg}{15kg}\times 100$

Percentage of excess weight = 200 %

Therefore, the percentage will be, 200%

This probability distribution shows the typical distribution of pitches thrown to a batter in a given at bat in a baseball game.

Answer:

0.35

Step-by-step explanation:

This probability distribution is shown below:

Pitch 1 2 3 4 5

Frequency 15 20 40 15 10

Probability 0.15 0.2 0.4 0.15 0.1

The probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 3)

X is the number of pitches thrown. Therefore:

P(X < 3) = P(X = 1) or P(X = 2)

The additive rule pf probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.

P(X < 3) = P(X = 1) or P(X = 2) = P(X = 1) + P(X = 2) = 0.15 + 0.2 = 0.35

The probability that the pitcher will throw fewer than 3 pitches to a batter = 0.35

Find CD if C(0,3) and D(4,7)

weeeeeb [17]

$C(0,3) \\
x_1=0 \\
y_1=3 \\ \\
D(4,7) \\
x_2=4 \\
y_2=7 \\ \\
\overset{\underline{\ \ \ \ }}{CD} =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(4-0)^2+(7-3)^2}= \\
=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{16 \times 2}=4\sqrt{2} \\ \\
\boxed{\overset{\underline{\ \ \ \ }}{CD} = 4\sqrt{2}}$
