After the tour, Tyler’s mom bought a pretzel and a bottle of water for each family member. The bottles of water cost $1.50 each.

Delicious77 [7]

Each pretzel is 4.5 $

1.50 • 5 = 7.5
7.5 - 30 = 22.5
22.5 / 5 = 4.5

so in conclusion, those are some expensive a** pretzels.

Translate the phrase into a variable expression: twice the sum of a number and 5

DIA [1.3K]

Answer:

'Twice the sum of a number and 5' can be translated into variable expression such as:

2(n + 5)

Step-by-step explanation:

Given the phrase

Twice the sum of a number and 5

First, let us breakdown the English Phrase

Let the number be = n

The sum of a number 'n' and 5 = n + 5

now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Thus,

'Twice the sum of a number and 5' can be translated into variable expression such as:

2(n + 5)

a fair coin is flipped 10 times. what is the probability of getting the same number of heads and tails

Dafna11 [192]

If you flip a coin one time, the probability to get a Head is

p = 1/2

The probability of not getting a head in a single toss is :

q = 1 - 1/2 = 1/2

Thus there is only one unique situation to get the same number of heads and tails : in 10 toss you need to get exactly five heads, it will means that the rest is the tails.

Now using Binomial theorem of probability, the probability of getting exactly x = 5 heads in a total of n = 10 tosses is :

P(X = 5) = $\frac{10!}{5!*5!} *(\frac{1}{2})^{5} *(\frac{1}{2})^{5}$ ≈ 0.246

So the probability of that is 24,6 %

Good Luck

Answer:

z = $-\frac{2}{5}$ or - 0.4

Step-by-step explanation:

8+2z = 6 - 3z

2z = 6 - 8 - 3z

2z + 3z = - 2

5z = -2

z = $-\frac{2}{5}$ or - 0.4
