Answer:
-4y/3
Step-by-step explanation:
If we have -4xy/3x, we just cancel the x since it is in the numerator and denominator. That leaves us with just -4y/3
The hours it would take to type 3.2 x 10^5 words is 1.33 x 10^2 hours.
<h3>How many hours would it take to
type 3.2 x 10^5 words?</h3>
Standard form is used in expressing large numbers in smaller numbers. It is used to transform large numbers into smaller number.
In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example: 1 x 10² is equivalent to 100
The first step is to determine how many words he can type in 1 hour : 40 x 60 = 2400 words = 2.4 x 10³
The second step is to divide 3.2 x 10^5 words by 2.4 x 10³
3.2 x 10^5 ÷ 2.4 x 10³ = 1.33 x 10^(5 - 3)
1.33 x 10^2 hours

Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
If I'm doing this correctly, you would need to multiply everything inside the parenthesis by 8. So it would be 8x-24y·8x+24y. I'm sorry if that's not right, but that is my interpretation of the problem. Hope I was of some assistance :)
Answer:
Total volume in the two glasses is 740 mL.
Step-by-step explanation:
Given:
Ratio of the volume of soda in glass A to the volume of glass B = 8/3 : 7/2
Volume of soda in glass A = 320mL
To Find :
The total volume in the two glasses = ?
Solution:
Let the volume of soda in glass B be x
then
Substituting the values ,
x = 420
Now total volume of soda in the two glasses
=> volume of soda in glass A + volume of soda in glass B
=> 320 + 420
=>740mL
