Answer:

$sah units^{3}$ represents the volume.

Step-by-step explanation:

Given

Length of edge as 's' and height as 'h'

Let 'a' be the area of base

Now, in the other three options the unit is only units and in sah the unit is $units^{3}$

So for any Volume we always have three dimensions that is Length, Breadth and Height.

so $Volume = L\times B\times H$

∴ $= meter\times meter\times meter$

∴ $= meter^{3}$

That is like $unit\times unit\times unit$

which is $units^{3}$

Answer:

a) MA conditional with C can be interpreted as A which is known and C which is unknown match

b) 10/11

c) 2/11

Step-by-step explanation:

A={A is the guilty party}

$M_A$ = {A blood type matches that of the guilty party}

C = {B is the guilty party}

$M_C$ = {B blood type matches that of the guilty party}

a) The chance is 10% because MA conditional with C can be interpreted as A which is known and C which is unknown match

b) the probability that A is the guilty party is given by $P(A/M_A)$ . Using bayes theorem:

$P(A/M_A)=\frac{P(M_A/A)P(A)}{P(M_A/A)P(A)+P(M_C/C)P(C)} =\frac{1*1/2}{(1*1/2)+(1/10*1/2)} =\frac{10}{11}$

c) the probability that B’s blood type matches that of the guilty party is given as $P(M_C/M_A)$ . Using LOTS Therefore:

$P(M_C/M_A)=P(M_C/M_A,A)P(A/M_A)+P(M_C/M_A,A)P(C/M_A)=\frac{1}{10}*\frac{10}{11} +1*\frac{1}{11} =\frac{2}{11}$

A race car is driven by a professional driver at 99 . What is this speed in and ? 1 mile = 1.61 kilometers 1 hour = 60 minutes E

Lena [83]

Let us assume that the given speed is in miles per hour.

A race car is driven by a professional driver at 99 mph.

We have to find the speed in kilometer per hour and kilometer per minutes

As 1 mile = 1.61 km

So, 99 miles = $99\times1.61=159.39$ kmph

1 km per hour = 0.0166 km per minute

So, 159.39 kmph = $159.39\times0.0166=2.6458$ km per minute

Hence, The speed is equivalent to 159.39 kilometers /hour, or 2.645 kilometers/minutes .

Suppose you have 20 coins that total $3.00. Some coins are nickels and some are quarters. Which of the following pairs of equati

kap26 [50]

Answer:

Step-by-step explanation:

n + q = 20

.05n + .25q = 3.00

5n + 25q = 300

n + q = 20

5n + 25q = 300

-5n - 5q = -100

20q = 200

q = 10 quarters

n + 10 = 20

n = 10 nickels

(10 nickels, 10 quarters)
