At a certain vineyard it is found that each grape vine produces about 10 lb of grapes in a season when about 800 vines are planted per acre. for each additional vine that is planted, the production of each vine decreases by about 1 percent. so the number of pounds of grapes produced per acre is modeled by
a(n) = (800 + n)(10 − 0.01n)
where n is the number of additional vines planted. find the number of vines that should be planted to maximize grape production.

The probability is approximately 0.9167 or 91.67%.

To find the probability that the sum of two dice numbers does not exceed 10, we need to determine the favorable outcomes (sums less than or equal to 10) and the total possible outcomes when rolling two dice.

There are 36 possible outcomes when rolling two dice because each die has six faces (1, 2, 3, 4, 5, and 6), and the total number of outcomes is obtained by multiplying the number of outcomes for each die (6 * 6 = 36).

Now let's determine the favorable outcomes (sums less than or equal to 10):

When the sum is 2: There is only one combination (1 + 1).

When the sum is 3: There are two combinations (1 + 2 and 2 + 1).

When the sum is 4: There are three combinations (1 + 3, 2 + 2, and 3 + 1).

When the sum is 5: There are four combinations (1 + 4, 2 + 3, 3 + 2, and 4 + 1).

When the sum is 6: There are five combinations (1 + 5, 2 + 4, 3 + 3, 4 + 2, and 5 + 1).

When the sum is 7: There are six combinations (1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, and 6 + 1).

When the sum is 8: There are five combinations (2 + 6, 3 + 5, 4 + 4, 5 + 3, and 6 + 2).

When the sum is 9: There are four combinations (3 + 6, 4 + 5, 5 + 4, and 6 + 3).

When the sum is 10: There are three combinations (4 + 6, 5 + 5, and 6 + 4).

Adding up the favorable outcomes, we get: 1 + 2 + 3 + 4 + 5 + 6 + 5 + 4 + 3 = 33.

Therefore, the probability that the sum of the two dice numbers does not exceed 10 is given by:

Probability = Favorable outcomes / Total outcomes = 33 / 36 = 11/12 ≈ 0.9167.

So, the probability is approximately 0.9167 or 91.67%.

The sum of the series s = ∑n=4^∞ 1/(n(n−1)) is 1/4.

To write the series s = ∑n=4^∞ 1/(n(n−1)) as a telescoping series, we need to manipulate the terms to cancel each other out and simplify the expression.

We can rewrite the series as:

s = ∑n=4^∞ (1/n - 1/(n-1))

Expanding the summation:

s = (1/4 - 1/3) + (1/5 - 1/4) + (1/6 - 1/5) + ...

Notice that the term -1/(n-1) in each subsequent term cancels out with the 1/n term in the next term, except for the first term (1/4 - 1/3).

We can simplify the expression by canceling out the terms:

s = 1/4 - 1/3 + 1/5 - 1/4 + 1/6 - 1/5 + ...

The consecutive terms cancel out, leaving only the first term:

s = 1/4

Therefore, the sum of the series s = ∑n=4^∞ 1/(n(n−1)) is 1/4.

The cost of the apples is 2.9 dollars.

The cost of the bananas is 5.7 dollars.

The total cost is 6 dollars, each apple cost $1.50 each banana cost $.30 and there’s two more bananas then apples.

Therefore,

let

x = number of apples

y = 2x

where

Therefore, using equations,

1.5(x) + y(0.30) = 6

Hence,

where

y = 2x

1.5(x) + 2x(0.30) = 6

1.5x + 0.6x = 6

2.1x = 6

divide both sides by 2.1

x = 6 / 2.1

Answer:

\(m\angle ABE=52^\circ\)

Step-by-step explanation:

Angles and Lines

The figure shows a kite ABCD where the following data is given:

\(m\BAE=28^\circ\)

\(m\BCE=58^\circ\)

We also know

\(BC\cong CD\)

\(AB\cong AD\)

Since triangle BCD is isosceles, it follows that:

\(m\angle CBE=m\angle CDE\)

And triangles BCD and DCE are congruent.

Thus:

\(m\angle BCE=m\angle DCE=58^\circ\)

And also:

\(m\angle BCE=58^\circ+58^\circ=116^\circ\)

Since the sum of internal angles of BCD is 180°

\(m\angle CDE=m\angle CBE= ( 180 - 116 ) / 2=32^\circ\)

The sum of angles of triangle CDE is 180°, thus

\(m\angle CED=180^\circ - 32^\circ - 58^\circ = 90^\circ\)

Angles CED and BEA are vertical (opposite), thus:

\(m\angle BCE=m\angle CED= 90^\circ\)

Finally, since the sum of the angles of triangle ABE is 180°

\(m\angle ABE= 180 - 90 - m\angle BAE\)

\(m\angle ABE= 180^\circ - 90^\circ - 28^\circ = 52^\circ\)

\(\mathbf{m\angle ABE=52^\circ}\)

Answer: -7

Step-by-step explanation:

Answer:

a = 0, b = 6, c = 4

Step-by-step explanation:

To obtain the values of a, b, c substitute the corresponding values of x into f(x) , that is

f(- 2) = - (- 2)² + (- 2) + 6 = - 4 - 2 + 6 = 0 ⇒ a = 0

f(0) = - 0² + 0 + 6 = 0 + 0 + 6 = 6 ⇒ b = 6

f(2) = - 2² + 2 + 6 = - 4 + 8 = 4 ⇒ c = 4

Solving a system of equations, we see that she can plant 20 tomatoes and 20 squashes.

Let's define the variables:

The space is enough for 40 plants, then:

t + s = 40

And we know that she has a total of $80 to spend (we assume that she spends it all)

t*$1 + s*$3 = $80

Then our system of equations:

t + s = 40

t*$1 + s*$3 = $80

To solve this, we can isolate one of the variables in the first equation, for e xample if we isolate t, we get:

t = 40  - s

Now we can replace that in the other equation:

(40 - s)*$1 + s*$3 = $80

Now we can solve that for s:

$40 - s*$1 + s*$3 = $80

s*$2 = $40

s = $40/$2 = 20

Then she will buy 20 units of squash, and the other 20 plants will be tomatoes.
