The z-score of the considered newborn having 4,000 g weight is [tex]\dfrac{4000 - \mu}{\sigma}[/tex]
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex])
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z tables, the p value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
For the considered case, the statement in the problem is missing the mean weight of the newborn and standard deviation of the data set of weights of newborn.
Thus, for them, we can consider variables in place of their actual values.
Let we have:
X = weights of newborns for some considered system (in grams)[tex]\mu[/tex] = mean weight of newborns (in grams)[tex]\sigma[/tex] = standard deviation of the data set of weights of newbornsThen, the z-score for X = 4000 is
[tex]z = \dfrac{x - \mu}{\sigma} = \dfrac{4000 - \mu}{\sigma}[/tex]
Thus, the z-score of the considered newborn having 4,000 g weight is [tex]\dfrac{4000 - \mu}{\sigma}[/tex]

if 1 pound=Rs.135 and dollar 1=Rs105 then convert pound 63 into dollar
Answer:
81
Step-by-step explanation:
63×135=8505
8505÷105=81#
In 63 pounds, there are equivalent 81 dollars.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement.
For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
Given is that -
1 pound = Rs.135
1 dollar = Rs. 105
Now, we can write that 1 rupee as -
Rs. 1 = 1/105 dollar
So, in 1 pound we can write -
1 pound = 135 x 1/105 dollars
63 pounds = 63 x 135 x 1/105 = 81 dollars
Therefore, in 63 pounds, there are equivalent 81 dollars.

how is multiplying two decimals different from multiplying a whole number and a decimal
Answer:
So multiplying decimal and whole number means it will always equal as a decimal. But multiplying decimal with decimal means could equal whole or decimal number
Step-by-step explanation:
Answer:
Essentially, they are same thing
Step-by-step explanation:
For example, 3 x 0.4 = 1.2
0.3 x 0.4 = 0.12
The only thing that changes are the amount of numbers behind the decimal. So when multiplying decimals, you just multiply like normal (3 x 4 = 12), then you count the amount of decimal spaces (two) and you take the number (12) and move the decimal place to the left twice. 12.0 would go to 1.2 if multiplying by a tenth.

Why is 0.9 x 0.9 > 0.9?
Question is in the image i uploaded!!
Answer:
4 pack
Step-by-step explanation:
£2.04 ÷ 4 is 51p. If we divide £2.04 by 4 (we are dividing it by 4 because that is the amount of rolls) it gives us how much 1 roll is in that pack. 1 roll = 51p in the 4 pack.
£4.68 ÷ 9 is 52p. If we divide £4.68 by 9 (we are dividing it by 9 because that is the amount of rolls) it gives how much 1 roll is in that pack. 1 roll = 52p.
Therefore, the 4 pack is cheaper as 1 roll costs less. The 4 pack is better value.
If 2 + x/8 = 2 then what is the value of 9x - 3?
Answer:
-3
Step-by-step explanation:
assuming that the x is the same in both problems, to get 2 as your solution, in the first problem x÷8 would have to equal 0. so x would have to be 0. sense 0 + 2 equals 2.
Then plug 0 into x in the first equation to check your work, and if it equals the answer givin to you (2), plug 0 into the equation you are trying to solve.
so 9×0 is 0, then 0 - 3 would give you -3

What was the Enlightenment, and how did it change they way people viewed government? Write your answer in complete sentences.
Answer:
The Enlightenment was a seventeenth- and eighteenth-century intellectual movement that aimed to better society via fact-based reasoning and investigation. The Enlightenment introduced secular ideas to Europe, changing people's perceptions of problems like liberty, equality, and individual rights. Today, such ideas are the bedrock of the world's most powerful democracies.
Step-by-step explanation:
two ideas that emerged from the Enlightenment:
Intellectuals like Jean-Jacques Rousseau and John Locke introduced the idea that no monarch should have absolute authority. Both claimed that leaders' authority came from the people, not from God. And, according to Locke, if people disagreed with their leader, they had the right to have their government replaced with one that honored their rights.
Pre-Enlightenment Equality Powerful individuals known as the nobility had exclusive privileges to buy land, avoid taxes, and hold privileged jobs across Europe, while the lowest elements of society battled to make ends meet. The Enlightenment questioned this system, with intellectuals such as John Locke arguing that all men are created equal and that no one should be born with more power than another.

what are the parts of the surface area ?
rest assured, there is no such thing like a general equation for the surface area of a prism.
well sure, there could be, but there are so many different variations, to describe them would be more complicated than the formula. so, we only have a general approach for the volume of such regular prisms (ground area × height).
but for the surface area we just have to break this problem into smaller problems we can easily solve and then add the results together.
so,
we see, there are 5 sides of this special prism.
top, bottom, left, right and front.
so, we need to calculate these 5 areas and simply add them up.
left and right are rectangles. one is
11×18 = 198 in²,
the other is
12×18 = 216 in², together they are 414 in².
the front is a rectangle
8×18 = 144 in²
top and bottom are equal triangles. each is
8 × height / 2
or per Heron's formula
A = sqrt(s(s -a)(s - b)(s -c)) where s = (a + b + c)/2
our s here is
s = (8 + 11 + 12)/2 = 15.5
A = sqrt(15.5×7.5×4.5×3.5) = sqrt(1830.9375) =
= 42.78945548... in²
both together are 85.57891095... in²
so, the total surface area is
414 + 144 + 85.57891095... = 643.578911... in²
if we need to round to e.g. whole square inches, this would be
644 in²
