Step-by-step explanation:

The punnet square is divided into 4 sections. RR means red, Rr means pink, and rr means white.

There is only one square with RR, so that's 25% red. (1 out of 4 squares)

Two squares are Rr, which means 50% are pink.

One square is rr, which means the remaining 25% is white.

Answer:

Mean = 30.68

Standard deviation = 6.095

Two standard deviations above the mean = 42.87

Step-by-step explanation:

Given the following data :

21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33; 34; 35; 36; 36; 36; 36; 38; 38; 38; 40

Mean = Σ(x) / n

n = 25

Σ (X) = 767

Mean (m) = 767 / 25

Mean (m) = 30.68

Standard deviation : sqrt[Σ(x - m) / n]

Using a calculator :

Standard deviation = 6.095 ( 2 decimal places)

2 standard deviations above the mean :

Mean + 2(standard deviation)

Mean + 2(6.095)

30.68 + 12.19

= 42.87

Find the area of the region bounded by the $y$-axis, the line $y=6$, and the line $y = \frac{1}{2}x$.

Iteru [2.4K]

For a better understanding of the solution provided here please go through the diagram in the file that has been attached.

As can be clearly seen from the question and the graph, the area is bounded by a straight line $y=\frac{1}{2}x$ which passes through the origin, the y axis and the horizontal line $y=6$ .

As we can see from the graph, this is a right triangle. To find the point of intersection of the horizontal line y=6 and the line $y=\frac{x\1}{2}x$ , we will have to equate the two as:
