Answer:

$Probability = \frac{1}{24}$

Step-by-step explanation:

Given

$Oranges = 3$

$Apples = 5$

$Banana = 2$

$Total = 10$

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

$Probability = P(Orange) * P(Apple) * P(Banana)$

$Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}$

The difference in the numerator is as a result of picking the fruit without replacement

$Probability = \frac{30}{720}$

$Probability = \frac{1}{24}$

A particle moves on a coordinate line with an acceleration at time t seconds of e^t/2 m/sec^2. At t=0 the particle is at the ori

castortr0y [4]

Hello,

A) $a=e^ \frac{t}{2} \\\\

v(t)=\int\ a\ dt=\int\ e^ \frac{t}{2}\ dt=2*e^ \frac{t}{2}+C\\\\v(0)=-4\\
 2*e^ \frac{0}{2}+C=-4\\
 C=-6\\\\

\boxed{v(t)= 2*e^ \frac{0}{2}-6}\\\\



$

B)
$2*e^ \frac{t}{2}-6=0\\\\

e^ \frac{t}{2}=3\\\\

t=2*ln(3)\approx{2,19722...}\\

$

C)

$x(t)=\int_0^6(2*e^ \frac{t}{2}-6})\ dt=\left[4*e^ \frac{t}{2}-6t\right]_0^6\\\\ =e^3-36-4=4e^3-40\approx{40.3421...}\\\\$

Correct Presentation of Question

Which numbers are domain? (-3,-2) (3,0)(-1,2)(1,2)

Answer:

Domain = {-3,-3,-1,1}

Step-by-step explanation:

Given

(-3,-2) (3,0)(-1,2)(1,2)

Required

Determine which numbers are domain

A function is always represented as thus (x,y) in this format (domain, range);

Tabulate the given data

x || y

-3 || -2

3 || 0

-1 || 2

1 || 2

The values under the x column are the domain;

Hence, the domain are {-3,-3,-1,1}
