Sara and Sam are each working on a science project in which they need to research the individual masses of the nine planets (inc

makkiz [27]

Answer:

2000 times

Step-by-step explanation:

Given

Sara:

$Mercury = 3.302 * 10^{23$

$Saturn = 5.685 * 10^{26$

Sam:

$Mercury = 3.302 * 10^{29$

$Saturn = 5.685 * 10^{32$

To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:

$Times = \frac{Saturn}{Mercury}$

Using Sara's measurement; this gives:

$Times = \frac{5.685 * 10^{26}}{3.302 * 10^{23}}$

Apply law of indices

$Times = \frac{5.685 * 10^{26-23}}{3.302}$

$Times = \frac{5.685 * 10^3}{3.302}$

$Times = 5.685/3.302 * 10^3$

$Times = 1.72 * 10^3$

Approximate

$Times = 2 * 10^3$

$Times = 2000$

A probability experiment is conducted in which the sample space of the experiment is S 1,2,3,4, 5,6,7,8, 9, 10, 11, 12]. Let eve

Alenkinab [10]

Answer:

$E\ n\ F = \{1, 5, 6,7\}$

$F\ n\ G =\{9\}$

$F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}$

$P(F\ U\ G) = \frac{3}{4}$

Step-by-step explanation:

Given

$S = \{1,2,3,4, 5,6,7,8, 9, 10, 11, 12\}$

$E = \{1,2, 3, 4, 5, 6,7\}$

$F =\{1,5,6, 7, 8,9\}$

$G = \{9,10, 11, 12\}$

$H = \{2, 3, 4\}$

Solving (5): E and F

Sets of E and F = E n F

$E\ n\ F = \{1,2, 3, 4, 5, 6,7\}\ n\ \{1,5,6, 7, 8,9\}$

List out common elements

$E\ n\ F = \{1, 5, 6,7\}$

<em>They are not mutually exclusive because </em> $n(E\ n\ F) \neq 0$ <em />

Solving (6): F and G

Sets of F and G = F n G

$F\ n\ G =\{1,5,6, 7, 8,9\}\ n\ \{9,10, 11, 12\}$

List out common elements

$F\ n\ G =\{9\}$

<em>They are not mutually exclusive because </em> $n(F\ n\ G) \neq 0$ <em />

Solving (7): F or G and P(F or G)

Sets of F or G = F U G

$F\ U\ G =\{1,5,6, 7, 8,9\}\ U\ \{9,10, 11, 12\}$

List all elements without repetition

$F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}$

Solving P(F U G)

$P(F\ U\ G) = \frac{n(F\ U\ G)}{n(S)}$

$n(F\ U\ G) = 9$

$n(S) = 12$

Hence;

$P(F\ U\ G) = \frac{9}{12}$

Divide by 3

$P(F\ U\ G) = \frac{3}{4}$
