The average height of sunflowers in a field is 64 in

Answers

This is from https://www.jiskha.com/questions/1578462/a-the-average-height-of-sunflowers-in-a-field-is-64-inches-with-a-standard-deviation-of

Answer:

a) The graph of a normal curve with a mean of 64" and a standard deviation of 3.5" is a bell-shaped curve with its

maximum value at x = 64.

Important points:

mean - 3 deviations: 64 - 3(3.5) = 64 - 10.5 = 53.5

mean - 2 deviations: 64 - 2(3.5) = 64 - 7 = 57

mean - 1 deviation: 64 - 3.5 = 60.5

mean: = 64

mean + 1 deviation: 64 + 3.5 = 67.5

mean + 2 deviations: 64 + 2(3.5) = 64 + 7 = 71

mean + 3 deviations: 64 + 3(3.5) = 64 + 10.5 = 74.5

b) If there are 3000 plants, approximately how many will be taller than 71"?

71" is 2 standard deviations above the mean. The region between two standard deviations below the mean and two standard deviations holds approximately 95% of the plants.

Therefore there will be approximately 5% of the plants divided equally between being taller than two standard

deviations above the mean and being shorter than two standard deviations below the mean. Thus, there will be

approximately 2.5% of the plants taller than 71": 0.025 x 3000 = 75 plants.

Scientists observe several strata that are tilted at an angle. what most likely caused the tilting?

Answers

The cause of the tilting is a result of moving the strata after they are being deposited.

What are strata?

Strata can be described as several layers of sediments, sand, and other materials that have been accumulated on the earth's surface, resulting in the development of sedimentary rocks. Strata have distinguishing characteristics that distinguish them from similar strata in the rock.

Strata in rocks can form and develop vertically or horizontally. Suppose the strata or layers of rocks appear tilted, this is due to the fact that the strata were moved after they were placed or deposited.

Assume that louisa carried an average balance of $1,000 from her credit card purchases over the past year. the a.p.r. on her credit card for the past year was 19.99%. approximately how much interest would louisa have paid over the course of the year?

Answers

The approximate amount of interest that louisa would have paid over the course of the year is; $200.

How to Calculate Simple Interest?

The amount of interest accrued in simple interest is given by the formula:

E = P*i*t

Where;

P is the balance.

i is the interest rate.

t is the time.

We are given;

Balance; P = $1,000, hence

APR of 19.99% and so i = 0.1999

time; t = 1 year.

Thus, the amount she will pay is:

E = 1000 * 0.1999 * 1

E = $199.9

Approximating to a whole number gives;

E = $200

Give (in order) the correct coefficients to balance the following reaction: h2sncl6 + h2s → sns2 + hcl

Answers

Let a, b, c, and d be coefficients in the balanced reaction,

a H₂SnCl₆ + b H₂S   →   c SnS₂ + d HCl

Count the atoms on both sides and set the amounts equal to each other:

• H : 2a + 2b = d

• Sn : a = c

• Cl : 6a = d

• S : b = 2c

Suppose a = 1. Then

6a = d   ⇒   d = 6

2a + 2b = d   ⇒   b = (d - 2a)/2 = 2

b = 2c   ⇒   c = b/2 = 1


So, the balanced reaction is

1 H₂SnCl₆ + 2 H₂S   →   1 SnS₂ + 6 HCl

The correct coefficients in order to balance the reaction is 1, 2, 1, 6

How to determine the correct coefficients to balance the equation?

To obtain the correct coefficients in order to balance the reaction, we shall obtain the balance equation. This is shown below:

H₂SnCl₆ + H₂S → SnS₂ + HCl

There are 2 atoms of S on the right side and 1 atom on the left side. It can be balanced by writing 2 before H₂S as shown below:

H₂SnCl₆ + 2H₂S → SnS₂ + HCl

There are 6 atoms of Cl on the left side and 1 atom on the right side. It can be balanced by writing 6 before HCl as shown below:

H₂SnCl₆ + 2H₂S → SnS₂ + 6HCl

Now, the equation is balanced. Thus, the correct coefficients needed to balance the reaction is 1, 2, 1, 6

A laser beam is to be directed through a small hole in the center of a circle of radius feet. the origin of the beam is feet from the circle. at what angle of elevation should the beam be aimed to ensure that it goes through the​ hole?

Answers

Based on the radius of the circle and the origin of the beam, the angle of elevation to ensure that the beam goes through the hole is 15.95°.

What angle of velocity is needed for beam accuracy?

The best operation to use would be the Tangent as the angle we are looking for is adjacent to the circle.

Solving gives:

tan (angle) = Radius of hole / Distance of beam

Angle = tan ⁻¹ (Radius of hole / Distance of beam)

= tan⁻¹ (10 / 35)
