If a seed is planted, it has a 75% chance of growing into a healthy plant.

Mathematics
1 answer:
Elan Coil [88]3 years ago
6 0

Answer:

9.72405%

Step-by-step explanation:

Binomial Probability

(N choose k) p^k (1-p)^(n-k)

N=7  seeds planted

p= 100% - 70% = 30% = 0.3 <--- we are interested in the plant NOT growing

(1-p) = 70% = 0.7  <--- 70% chance the plant will survive and grow

k=4  <--- we want four of them to fail

The probability is:

 (7 choose 4) * (0.3)^4  (0.7)^3 =

 7!/(4!3!) (0.3)^4 (0.7)^3  =

 (7*6*5/3*2) (0.3)^4 (0.7)^3 =

 7*5 (0.3)^4 (0.7)^3 =

 35 * 0.0081 * 0.343 = 0.0972405 = 9.72405%

Writing an Equation from a Table
Anastasy [175]

The equation of the line will be y = 4x. Then the correct option is A.

<h3>What is the equation of line?</h3>

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

Writing an Equation from a Table

A 2-column table with 6 rows. Column 1 is labeled x with entries 8, 12, 16, 20, 24, 28. Column 2 is labeled y with entries 2, 3, 4, 5, 6, 7.

Then at (2, 8) and (3, 12), we have

y – 8 = [(12 – 8) / (3 – 2)] (x – 2)

y – 8 = 4x – 8

     y = 4x

Then the correct option is A.

A truck hauls wheat to a storage granary. It carries a total of 4,970 bushels of wheat in 14 trips. How much does the truck haul
Alex17521 [72]

Answer:

355 bushels.

Step-by-step explanation:

To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat  between the total of trips of the truck.

The total amount of bushels is 4970 and the total of trips is 14.

Then, the amount of bushels for each trip would be 4970/14 = 355.

Therefore, the truck hauls 355 bushels of wheat each trip.

We are already given with the function to solve for the area:
<span>A(θ) = 16 sin θ ⋅ (cos θ + 1)
</span>
We simply have to substitute the value of the angle into the function. So,
If <span>θ = 90°,
A(</span>90°) = 16 sin (90°) ( cos (<span>90°) + 1 )

Using the calculator or the definition of trigonometric functions at angle of </span><span>90°, we get the value of the area:
