64/100*75=48 That is the answer
Answer:
2x + 4
Step-by-step explanation:
Let R = Ralph's age
and x = Sarah's age
Then Ralph's age in 4 years = R + 4
and Sarah's age in four years = x + 4
Thus, R + 4 = 2(x + 4)
Distribute the 2 R + 4 = 2x + 8
Subtract 4 from each side R = 2x + 4
Ralph's age is 2x + 4.
Answer:
ASA because there's two angles and a side
The normal distribution is also known as the Gaussian distribution. The correct option is B, while the approx z-score is 0.31.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, the correct option is B, while the approx z-score is 0.31.

The first thing I would do is to multiply everything by 3 to get rid of the fraction:
3M = 3wp + yp²
We can then take the 3M over to the other side to leave a quadratic equation:
yp² +3wp - 3M = 0
The easiest way to solve this for p is to use the quadratic formula:
p = <span>± (</span>√(9w²+12yM))/2y
