a) The average height of sunflowers in a field is 64 inches with a standard deviation of 3.5 inches. Describe a normal curve for the distribution, including the values on the horizontal axis at one, two, and three standard deviations from the mean. b) If there are 3,000 plants in the field, approximately how many will be taller than 71 inches?

Answers

The values on the horizontal axis are:
at 0 = 64
at one standard deviation (lower, upper) = (60.5 , 67.5)
at two standard deviation (lower, upper) = (57 , 71)
at three standard deviation (lower, upper) = (53.5 , 74,5)

B. P(x > 71) = 1 - P(x < 71) = 1 - P[z < (71 - 64)/3.5] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
Therefore the no of plants taller than 71 inches will be approximately 0.02275 * 3000 = 68

Which functions are symmetric with respect to the origin?y = arcsinx and y = arccosx
y = arccosx and y = arctanx
y = arctanx and y = arccotx
y = arcsinx and y = arctanx

Answers

The function are symmetric with respect to the origin is y = arcsinx and y = arctanx and this can be determined by using the trigonometric property.

The following steps can be used in order to determine which functions are symmetric with respect to the origin:

Step 1 - Check all the options given in order to determine which functions are symmetric with respect to the origin.

Step 2 - Substitute (x = 0) in option a), that is:

$\rm y = sin^(-1)(0)=0$

$\rm y = cos^(-1)(0)=1.57$

Step 3 - Substitute (x = 0) in option b), that is:

$\rm y = cos^(-1)(0)=1.57$

$\rm y = tan^(-1)(0)=0$

Step 4 - Substitute (x = 0) in option c), that is:

$\rm y = tan^(-1)(0)=0$

$\rm y = cot^(-1)(0)=1.57$

Step 5 - Substitute (x = 0) in option d), that is:

$\rm y = tan^(-1)(0)=0$

$\rm y = sin^(-1)(0)=0$

Answer:

The correct option is;

y = arcsinx and y = arctanx

Step-by-step explanation:

The given options are;

1) y = arcsinx and y = arccosx

Here, we have at the origin, where x = 0, arccosx ≈ 1.57 while arcsinx = 0

Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin

2) y = arccosxy and y = arctanx

Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical

3) y = arctanx and y = arccotx

Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical

4) y = arcsinx and y = arctanx

Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.

A house cost $120,000 when it was purchased. The value of the house increases by 10% each year. What is the rate of growth each month?select the correct answer below.A) 0.797%
B) 0.00797%
C) 0.833%
D) 0.00833%

Answers

Answer: C) 0.833%

Step-by-step explanation:

Given: Cost price of house = $120,000

The rate of increase of its cost = 10%

Therefore, the increase amount of house per year =10% of $120,000

$=(10)/(100)*120000=\$12,000$

Now, the amount increase each month= $(12000)/(12)=\$1000$

Let r be the rate of growth each month, then

r% of $120,000=1000

$\Rightarrow(r)/(100)*120000=1000\n\Rightarrow\ r*1200=1000\n\Rightarrow\ r=(1000)/(1200)=0.833\%$

Answer:

0.797%
