We know that the word equation for the reaction taking place during photosynthesis is:

carbon dioxide + water + sunlight → glucose + oxygen

Therefore, the more the reactants are provided, the more the plant will grow. The lesser the reactants, the lesser the growth. Providing products will not alter the rate of photosynthesis. The factors may be grouped as:

Increase plant growth:

-increase sunlight

-increase carbon dioxide

-increase water

No effect on plant growth:

-increase glucose

-increase oxygen

-decrease glucose

-decrease oxygen

Decrease plant growth:

-decrease water

-decrease sunlight

-decrease carbon dioxide

]]>The post What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample mean of $6.88 per basket. assume that the standard deviation is known to be $1.92 per basket. find a 90% confidence interval for the population mean price per basket that farmers in this region get for their peach crop appeared first on EduHawks.com.

Given:

Sample size, n = 40

Sample mean, xb = $6.88

Population std. deviation, σ = $1.92 (known)

Confidence interval = 90%

Sample size, n = 40

Sample mean, xb = $6.88

Population std. deviation, σ = $1.92 (known)

Confidence interval = 90%

Assume normal distribution for the population.

The confidence interval is

(xb + 1.645*(σ/√n), xb – 1.645*(σ/√n)

= (6.88 + (1.645*1.92)/√40, 6.88 – (1.645*1.92)/√40)

= (7.38, 6.38)

Answer: The 90% confidence interval is (7.38, 6.38)

Suppose you read in your local newspaper that 45 officials in student services earn an average of $50,340 each year. Assume that the standard deviation is $10,780 for salaries of college officials and student services. Find a 90% confidence interval for the population mean salaries of such personnel. Round your answer to the nearest dollar and don;t forget to use the $ sign. appeared first on EduHawks.com.

]]>Since sample size is > 40, we use the z-score

in calculating for the confidence interval.

The formula is given as:

Confidence Interval = X ± z * σ / sqrt (n)

Where,

X = mean = $50,340

z = z-score which is taken from standard distribution

tables at 90% confidence interval = 1.645

σ

= standard deviation = $10,780

n = sample size = 45

Substituting to the equation:

Confidence Interval = 50,340 ± 1.645 * 10,780 / sqrt (45)

Confidence Interval = 50,340 ± 1,607

Confidence Interval = $48,733 to $51,947

**Therefore the salary range of the personnel is $48,733 to $51,947.**

]]>The post Find the area of the shaded region. Round answers to the nearest tenth. Assume all inscribed polygons are regular. appeared first on EduHawks.com.

]]>We can calculate for the area of the shaded region by 1)

calculating the area of circle, 2) calculating for area of triangle, and 3)

calculating for area of the segment below the triangle. Then subtract 2 and 3

from 1.

1) Area of circle, Ac = π r^2

Ac = π (6)^2

Ac = 113.10

2) Area of triangle, At

The triangle is an equilateral triangle with angles on each

corner equal to 60 degrees. Meanwhile, the 3 angles at the center is 120

degrees each since a circle is 360 degree. We know that the radius (line from

centerpoint to corner) is equivalent to 6. Using the cosine law, we can calculate

for the length of one side.

s^2 = 6^ + 6^2 – 2 (6) (6) cos 120

s^2 = 108

s = 10.4

Since this is an equilateral triangle therefore all sides

are equal. The area for this is:

At = (sqrt3 / 4) * s^2

At = 46.77

3) Area of segment, As is given as:

As = [ (r^2) / 2 ] ( θ rad – sin θ )

As = [(6^2) / 2] (120 * π / 180 – sin 120)

As = 22.11

Therefore the area of shaded region is:

A = 113.10 – 46.77 – 22.11

**A = 44.22**
