KonstantinChe [14]

Answer:

0.0656

Step-by-step explanation:

For each message, we have these following probabilities:

90% probability it is spam.

10% probability it is legitimate.

Compute the probability that the first legitimate e-mail she finds is the fifth message she checks:

The first four all spam, each with a 90% probability.

The fifth legitimate, with a 10% probability.

$P = (0.9)^{4} \times 0.1 = 0.0656$

Answer:

14.4 inches to the nearest tenth.

Step-by-step explanation:

The square has area x^2 where x is the length of each side so:

x^2 = 13

x = √13.

The perimeter is the distance all around the square and this is 4x so we have the answer 4 *√13

14.422 inches.

Evaluate the expressiin when a=6, b=3, and c=2: c(b+a)-a= please help

Setler [38]

Answer:

$\huge{ \fbox{ \tt{12}}}$

Step-by-step explanation:

$\underline{ \sf{Given}} : \sf a=6, \: b=3 \: and \: c=2$

$\underline{ \sf{To \: find }} : \sf{Value \: of \: the \: given \: expression}$

$\underline{ \underline{ \mathfrak{Let's \: solve}}} :$

$\bigstar{ \tt{ \: c \: ( \: b \: + \: a \: ) - \: a}}$

$\text{Step \: 1 \: } :$ Plug the values of a , b and c

$\mapsto{ \tt{ \: 2 \: ( \: 3 \: + \: 6 \: ) \: - \: 6}}$

$\text{Step \: 2} : \sf{ \: Add \: the \: numbers : 6 \: and \: 3}$

$\mapsto{ \sf{ \: 2 \: * \: 9 \: - \: 6 \: }}$

$\text{Step \: 3 \: } : \sf{ \: Multiply \: the \: numbers : 9 \: and \: 2}$

$\mapsto{ \sf{18 - 6}}$

$\text{Step \: 4 \:} : \sf{Subtract \: 6 \: from \: 18}$

$\mapsto{ \sf{ \: 12}}$

Note : Just follow the PEMDAS rule ( See attached picture )

Hope I helped!

Best regards! :D
