What is 23/8 as a decimal?

2 answers:

7 0

To write 23/8 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 23 by 8 what we write down as 23/8 and we get 2.875 

And finally we have: 
23/8 as a decimal equals 2.875

Hello there!

In order to " $convert$ " a $'fraction'$ to a $decimal$ you'll need to $divide$ the $numerator$ from the $denominator$

So, $23$ ÷ $8$ equals $2.875$

So, therefore $\frac{23}{8}$ as a $decimal$ would be $2.875$

Good luck on your assignment and enjoy your day!

This graph shows the water level in a bathtub, in inches, overtime (in minutes). what situation could match the graph?

user100 [1]

Answer:

Alison turns on the water and allows it to run in the tub for a few minutes. She then turns the water off while she runs to answer the front door. Alison comes back and allows water to run into the tub for a couple more minutes before she takes a short bath. After the bath, Alison allows the water to completely drain from the tub.

Is B equal to C in this geometry problem? I just need to know, that and then I can solve the rest.

In the right angled triangle ACD shown with isosceles triangle ABC and ADC, AB = AC = AD

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

A triangle is a polygon that has three sides and three angles. Types of triangles are isosceles, equilateral and scalene.

In the diagram shown:

AB = AC = AD

In the right angled triangle ACD shown with isosceles triangle ABC and ADC, AB = AC = AD

Two companies, A and B, make express delivery for small-item packages in a city. Company A charges a flat fee of RM70 per packag

bazaltina [42]

Using the normal probability distribution and the central limit theorem, it is found that:

a) There is a 0.1922 = 19.22% probability that Company B would charge more than Company A to deliver a small-item package.

b) The mean amount charged is of RM 51.5, with a standard deviation of 21.35.

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

By the Central Limit Theorem:

When a fixed constant k multiplies a variable, the mean is $k\mu$ and the standard deviation is $k\sigma$
When two normal variables are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

In this question, b is needed to solve a, so I am going to place the solution to item b first.

Item b:

Flat fee of RM20(not considered for the standard deviation), plus a variable fee of RM3.5, hence:

$\mu_B = 20 + 3.5(9) = 51.5$

$\sigma = 6.1(3.5) = 21.35$

The mean amount charged is of RM 51.5, with a standard deviation of 21.35.

Item a:

This probability is $P(B - A) > 0$ . For the distribution, we have that:

$\mu_{B-A} = \mu_B - \mu_A = 51.5 - 70 = -18.5$

Since A has a constant fee, it's standard deviation is 0, hence:

$\sigma_{B-A} = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{21.35^2} = 21.35$

The probability is 1 subtracted by the p-value of Z when X = 0, so:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{0 + 18.5}{21.35}$

$Z = 0.87$

$Z = 0.87$ has a p-value of 0.8078.

1 - 0.8078 = 0.1922.

0.1922 = 19.22% probability that Company B would charge more than Company A to deliver a small-item package.

For the function: f(x) = 21 + 2x − 5x2 Find f(3)

allochka39001 [22]

F(3)=-18

You just replace x for three for your equation and then use Ofer of operations to solve it.

So f(3)= 21+ 2(3)-5(3)^2

The exponent goes first: f(3)= 21+ 2(3)-5(9)

Next is multiplication: f(3)= 21+ 6-45

Now add: f(3)= 27-45

Finally subtract: f(3)= -18

Hope this helps!
