Answer:

I think the answer is around 24 to 25 dollars.

Bella paid a total amount of $13.49.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Bella ordered a $6 smoothie.

Sales tax = 9%

So, amount after tax

= 6 + 9% of 6

= $6.54

and, tip= 15%

Amount after tip

= 6 + 0.15 x 6

= $6.9

Thus, Bella paid

= 6.54 + 6.9

= $13.49

Answer:

the probability that the song should be played on accurately  3 days out of 5 days is 0.051

Step-by-step explanation:

Given that

The probability that a particular song is played is 1 by 5

We need to find out the probability that the song should be played on accurately  3 days out of 5 days

So,

[tex]P(x = 3) = \frac{5!}{3! (5 - 3)!} (\frac{1}{5})^3(1 - \frac{1}{5})^{5-3}[/tex]

= 0.051

Hence, the probability that the song should be played on accurately  3 days out of 5 days is 0.051

Length of leg of triangle =  

Step-by-step explanation:

We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.

Let us assume the following labeling of the diagram, as attached in the answer area.

The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.

i.e. The sides XY and YZ will be equal.

Let XY = YZ = x cm

It is known that in a right angled triangle, pythagorean theorem holds well.

Answer:

[tex]\boxed {\boxed {\sf z=2.8}}[/tex]

Step-by-step explanation:

The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:

[tex]z= \frac{x- \bar x}{s}[/tex]

where x is the value, x-bar is the mean, and s is the standard deviation.

We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.

Substitute the values into the formula.

[tex]z= \frac{ 39-25}{5}[/tex]

Solve the numerator.

[tex]z= \frac{ 14}{5}[/tex]

[tex]z=2.8[/tex]

The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Step-by-step explanation:

Answer:  standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

The probability of flipping a coin 85 times and getting tails 50 times or fewer 99.8%, the correct option is B

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

The coin is flipped 85 times

Now,

The probability of flipping a coin and getting tails on any single flip is 0.5 (assuming it's a fair coin). We can model this scenario using a binomial distribution, where:

n = 85 (the number of coin flips)

p = 0.5 (the probability of getting tails on any single flip)

x = 50 (the maximum number of tails we want to allow)

We want to find the probability of getting 50 tails or fewer, so we need to calculate the cumulative probability of the binomial distribution up to x = 50. We can use a binomial probability calculator or a spreadsheet program to do this calculation.

Using a binomial probability calculator, we get:

P(X ≤ 50) = 99.8%

Therefore, the probability will be 99.8%.
