"Dram" is a unit of volume, whereas "gram" is a unit of mass.
They can't be directly converted. If they both refer to a sample
of some substance, then the conversion depends on the density
of the substance. All we can say for sure by way of an answer is:
To change 'drams' to 'grams', replace the 'd' with 'g'.
Hey there Alex,
With a problem like that, you have to get the variable (in this case it is W) by itself.
Now W is being divided by 4-13 which is -9, so it ends up looking like this.
In order to get W by itself, you need to multiply out the denominator.
That means take the denominator and multiply both sides by it.
The -9's cancel out and you are left with W = (11 x -9) which is -99.
W = -99
90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.
<u>Construction</u> is a process in which required<em> steps</em> are considered to draw a given shape by the use of construction <u>instruments</u> and <u>materials</u>. Thus to correct the <u>error</u> in the given question, the third arc should be drawn <u>centered</u> at point F. Answer is option A.
Majorly, the use of a<em> straight edge</em> and a <u>pair</u> of compasses to draw the image of a given object is referred to as <u>construction</u>. Which required <em>adhering </em>to some steps.
The <em>construction</em> of a <u>parallel</u> line through a <em>given</em> point to a given <em>line </em>involves following the <u>appropriate</u> procedure. If not, an error would be committed which would result in an i<em>nappropriate</em> shape or figure.
Therefore, to fix the <u>error</u> in the given question, it is important that the <em>third</em> arc should be drawn<u> centered</u> at point F. Thus, the correct answer is <em>option</em> A.

Answer:
We are 99% sure that the true population mean falls in interval .
Step-by-step explanation:
Let be the sample proportion.
As per given , we have
Standard error = 0.024
Critical value for 99% confidence interval :
Confidence interval is given by :-
Then, the 99% confidence interval will be :-
Hence, a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter :
Interpretation : We are 99% sure that the true population mean falls in interval .
