Monica [59]

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

Show your work for the math problem
konstantin123 [22]

Answer: x=26

Step-by-step explanation:

Simplifying

2x + 3x + 50 = 180

Reorder the terms:

50 + 2x + 3x = 180

Combine like terms: 2x + 3x = 5x

50 + 5x = 180

Solving

50 + 5x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-50' to each side of the equation.

50 + -50 + 5x = 180 + -50

Combine like terms: 50 + -50 = 0

0 + 5x = 180 + -50

5x = 180 + -50

Combine like terms: 180 + -50 = 130

5x = 130

Divide each side by '5'.

x = 26

Simplifying

x = 26

A game advertises, EVERYONE IS A WINNER! It costs $1 to play. You get to choose a card from a standard deck of 52
SashulF [63]

Answer:

X_{red} = 3, p(red) =\frac{1}{2}

X_{black} = 2, p(red) =\frac{1}{2}

And the cost of play would be 1 with probability 1 for any given game. Then we can find the expected value like this:

E(X) = 3 *\frac{1}{2} +2 \frac{1}{2} -1

And solving we got:

E(X) = 1.50

And then the best answer for this case would be:

$1.50

Step-by-step explanation:

For this case we can calculate the expected value with this formula:

E(X) =\sum_{i=1}^n X_i P(X_i)

We assume that the standard deck is formed just with red and black cards. For this case we have the following info:

X_{red} = 3, p(red) =\frac{1}{2}

X_{black} = 2, p(red) =\frac{1}{2}

And the cost of play would be -1 with probability 1 for any given game. Then we can find the expected value like this:

E(X) = 3 *\frac{1}{2} +2 \frac{1}{2} -1

And solving we got:

E(X) = 1.50

And then the best answer for this case would be:

$1.50
