The GPA's at RHS are Normally distributed with a mean of 2.8 and a standard deviation of 0.7. Let G = a random student's GPA.
Alja [10]

The value of  P(G<2.5) is 14.23%.

What is observation?

The active gathering of data from a primary source is observation. Observation of living things makes use of the senses. Using scientific tools to perceive and record data is another way that observation may be used in science.

The $z$-score for this observation of 2.30 is:

Z= (2.3-2.8)/0.7=-1.71

The table shows a value of 0.8577 , and because this z-score is negative, this is the proportion greater than a GPA of 2.30. So the proportion less than 2.30 is 1-0.8577 =0.1423 . Expressing it mathematically we have:

$$\begin{aligned}P(X \leq 2.7) & =P(Z \leq-1.07) \\& =1-P(Z \geq-1.07) \\& =1-P(Z \leq 1.07) \\& =1-0.8577 \\& =0.1423=14.23 \%\end{aligned}$$

One side of a square is 10 units. Which is greater, the number of square units for the área of the square or the number of units
ValentinkaMS [17]
The area of the square would be greater. To get the area of a square you need to multiply the length and width of the square, therefore you would multiply 10x10 which comes out to be 100. The perimeter would only be 40.

If given the following AP what is the common difference 10, 15, 20
ANTONII [103]

Answer:

The common difference of the given AP is d=5.

Step-by-step explanation:

Given the sequence

10,\:15,\:20

An Arithmetic sequence has a constant difference 'd' and is defined by

a_n=a_1+\left(n-1\right)d

Computing the common difference of all the adjacent terms

10,\:15,\:20

15-10=5,\:\quad \:20-15=5

As the difference between all the adjacent terms is the same and equal to

d=5

Therefore, the common difference of the given AP is d=5.
