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 ballga

Inessa [8989]

Events A and B are termed independent when

$Pr(A\cap B)=Pr(A)\cdot Pr(B),$

if not, events A and B are classified as dependent.

The events A, B and A∩B are:

A - Jane plans to attend a ballgame on Monday;
B - Kate intends to go to a ballgame on Monday;
A∩B - Both Kate and Jane will be at the ballgame on Monday.

$Pr(A)=0.73,\ Pr(B)=0.61,\ Pr(A\cap B)=0.52.\\ \\ Pr(A)\cdot Pr(B)=0.73\cdot 0.61=0.4453\neq 0.52=Pr(A\cap B).$

Answer: events A and B are dependent

tester [8808]

Answer:

$Rate = 1.1/hr$

Step-by-step explanation:

Given

$Start = 23$

$End = 16$

$Hours = 6\frac{1}{2}h$

Required

Calculate the hourly rate

First, we will determine the amount of ice cream that was sold

$Ice\ Cream = 23 - 16$

$Ice\ Cream = 7$

Next, calculate the average hourly rate:

$Rate = Ice\ Cream/Hours$

$Rate = 7/6\frac{1}{2}h$

$Rate = 7/\frac{13}{2}h$

$Rate = 7*\frac{2}{13h}$

$Rate = \frac{14}{13h}$

$Rate = 1.07692307692/hr$

$Rate = 1.1/hr$ -- Approximated

Answer:

Hello! Your question appears to be missing details; here is the complete version

Ix = 0 Ux = $\sqrt{y-9z^2}$

Iz = 0 Uz = $\frac{\sqrt{y} }{3}$

Iy = 5 Uy = 10

Step-by-step explanation:

Ix = 0 Ux = $\sqrt{y-9z^2}$

Iz = 0 Uz = $\frac{\sqrt{y} }{3}$

Iy = 5 Uy = 10

Brad buys a pack of 12 bottles of energy drink for £9.25 he then sells all bottles for £1 each. Work out brads percentage profit

Svet_ta [9486]

La ganancia de Brad fue del 30%

Explicación adicional:

La ganancia es el dinero obtenido al vender un producto por encima de su costo original.

La fórmula para calcular la ganancia es:

$Profit= Selling\ price-Purchase\ price$

Datos:

Precio de compra del paquete de bebidas energéticas = £9.25

Precio de venta por botella = £1

Precio total por 12 botellas = 1 * 12 = £12

Ganancia = Precio de venta - Precio de compra

= 12 - 9.25

= £2.75

Así, la ganancia de Brad fue de £2.75

Luego,

Porcentaje de ganancia = (Ganancia / Precio de compra) * 100

= (2.75 / 9.25) * 100

= 0.30 * 100

= 30%

La ganancia de Brad fue del 30%
