Answer:
The answer is 221/2 or 73 ⅔
Step-by-step explanation:
5 ⅔ = (3 × 5 + 2) ÷ 3 = 17/3
Now,
17/3 × 13 = 221/2 = 73 ⅔
Thus, The answer is 221/2 or 73 ⅔
Answer: 4x² + x - 2
Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²
Now let's work on the second part:
Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals
12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:
4x² + x - 2.
Using the normal distribution, it is found that 10.56% of the apples weigh less than Jermaine's apple.
--------------------
In a <em>normal distribution</em> with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure X 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, that is, the proportion of measures that are less than X.
In this problem:
- Mean of 0.33 pounds, thus
. - Standard deviation of 0.06 pounds, thus
. - The proportion that is less than 0.25 pounds is the p-value of Z when X = 0.25, thus:
has a p-value of 0.1056.
0.1056 x 100% = 10.56%.
10.56% of the apples weigh less than Jermaine's apple.

Answer:
Step-by-step explanation:
get the x alone by subtracting 3 from each side.
3x+3-3<36-3
3x<33
divide by three
3x/3<33/3
x<11
If y = 0.75 when x = 0.5, set up a proportion -
0.75:0.5
x:3
Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.
