Answer:

The second one

Step-by-step explanation:

Answer:

0.00987

Step-by-step explanation:

Using binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

p = 0.725 ; number of trial, n = 30

Number of winning, x = 16

1 - p = 1 - 0.725 = 0.275

P(x = 16) = 30C16 * 0.725^16 * 0.275^14

P(x = 16) = 119759850 * 0.725^16 * 0.275^14

P(x = 16) = 0.00987

Hence, the probability of winning 16 of their next 30 games is 0.00987

Answer:

u = -2

Step-by-step explanation:

Here is how to solve the equation,

\(7 - 6u = 5u + 29\\\)

What I did first was isolate the variable by adding to both sides.

7 - 6u = 5u + 29

  + 6u   +6u      

7 = 11u + 29

Our new equation now needs to be simplified by subtracting from both sides, like so...

 7 = 11u + 29

-29          -29  

-22 = 11u

Time to divide and solve for the variable u.

\(\frac{-22}{11}\) and \(\frac{11u}{11}\)

That leaves us with, -2 = u

Answer:

It can be written as:

(9m)(9m)(9m)(9m)

Step-by-step explanation:

Answer:

First term (a ) = -5

Common difference (d) = -2--5 = -2+5 = 3

Nth term = a + (n-1)d

= -5 + (n-1)3

= -5 + 3n - 3

= 3n - 8

The nth term rule is 3n - 8

Hope this helps.

The sequence is an illustration of an arithmetic sequence.

The nth rule is: (d) \(a_n = 3n -8\)

We have:

\(a_1 = -5\) -- the first term

Next, we calculate the common difference (d)

\(d = a_2 - a_1\)

So, we have:

\(d = -2 -(-5)\)

\(d = -2 +5\)

\(d = 3\)

The nth rule is calculated using:

\(a_n = a_1 + (n - 1)d\)

So, we have:

\(a_n =-5 + (n - 1) \times 3\)

Open bracket

\(a_n =-5 + 3n - 3\)

Collect like terms

\(a_n = 3n -5- 3\)

\(a_n = 3n -8\)

Hence, the nth rule is: \(a_n = 3n -8\)

Answer:

Midpoint of side EF would be (-.5,4.5)

Step-by-step explanation:

We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:

e=a+c/2,f=b+d/2

Here we have to find the mid-point of side EF.

E(-2,3) i.e. (a,b)=(2,3)

and F(1,6) i.e. (c,d)=(1,6)

Hence, the coordinate of midpoint of EF is:

e=-2+1/2, f=3+6/2

e=-1/2, f=9/2

e=.5, f=4.5

SO, the mid-point would be (-0.5,4.5)

Answer:

5 weeks

Step-by-step explanation:

A

y=10 x 2.5 +25                

y= 25+25

y=50

y=10 x 5 +25

y=50+25

y=75

y=10 x 15 +25

y=150+25

y=175

y=10 x 75 +25

y=750+25

y=775

B

y= 5 x 2.5 + 50

y=12.5 + 50

y=62.5

y = 5 x 5 + 50

y=25+50

y=75

y = 5 x 15 + 50

y=75+50

y=125

y = 5 x 75 + 50

y= 375 +50

y=425

So its 5 weeks since both get 25

You can also do a equation method

     5x + 50=10x + 25

-5x(                              )-5x

         50=5x+25

-25(                   )-25

            25=5x

÷5(                              )÷5

5=x

so 5 weeks again

The difference in the cost of 600 text messages plan

Representing the given data as; Cost to Number of text messages, we have:

\(Dial\ Up = \$5 : 100\)

and

\(Ring\ Ring= \$8 : 200\)

Multiply the dial-up by 6 to get the cost of 600

\(Dial\ Up = \$5 *6 : 100 * 6\)

\(Dial\ Up = \$30 : 600\)

So, the cost of 600 text messages is $30 --- for dial-up

Multiply the Ring Ring by 3 to get the cost of 600

\(Ring\ Ring= \$8 *3: 200*3\)

\(Ring\ Ring= \$24: 600\)

So, the cost of 600 text messages is $24 --- for Ring Ring

The difference (d) is:

\(d = \$30 - \$24\)

\(d = \$6\)

Answer:

Length = 8 meters

Width = 6 meters

Step-by-step explanation:

Given the following information:

Perimeter of a rectangular vegetable patch: 2(L + W) = 28 meters

Area = L × W = 48 m²

We can solve for the dimensions by using both equations.

First, let's use the formula for the perimeter of the rectangular vegetable patch, and isolate one of the given variables:

2(L + W) = 28

Divide both sides by 2:

\(\frac{2(L + W)}{2} = \frac{28}{2}\)

L + W = 14

Subtract W from both sides to isolate L:

L + W - W = 14 - W

L = 14 - W

Next, we'll take the formula for the area, and substitute the value for the L from our previous step:

A = 48  =  L × W

48  = W × (14 - W)

Distribute W into the parenthesis:

48 = 14W - W²

Add W² and subtract 14W to both sides:

W² - 14W + 48 = 14W - 14W - W² + W²

W² - 14W + 48 = 0   ⇒ This represents a quadratic equation in standard form. We can use the coefficient and constant values to solve for its roots.

a = 1, b = -14, and c = 48

Substitute these values into the quadratic equation:

\(x = \frac{-b +/- \sqrt{b^{2}-4ac}}{2a}\)

\(x = \frac{14 +/- \sqrt{(-14)^{2}-4(1)(48)}}{2(1)}\)

\(x = \frac{14 +/- \sqrt{196-192}}{2}\)

\(x = \frac{14 +/- \sqrt{4}}{2}\)

\(x = \frac{14 + 2}{2}\), \(x = \frac{14 - 2}{2}\)

x = 8, x = 6

Now, we can substitute these values into the formulas for the perimeter and area to find the true dimensions of the rectangular vegetable patch.

Perimeter: 2(L + W) = 2(8 + 6) = 28 meters

Area = L × W = 8 × 6  = 48 m²

Therefore, the dimensions of the rectangular vegetable patch are:

Length = 8 meters

Width = 6 meters

Dimensions: 8 × 6 meters.

Answer:

n= 18 over 5

Step-by-step explanation:

Answer: n = 3.6

Step-by-step explanation: When solving an equation that contains decimals, we want to get rid of the decimals as soon as possible.

Notice that 1.2 is taken to the tenths place

but 0.68 is taken to the hundredths place.

To get rid of all decimals in the equation, multiply both

sides by the greatest power of 10 that is required.

So here we multiply both sides by 100 which

moves all decimals 2 places to the right.

So we have (100)(1.2n + 0.68) = (5)(100).

This gives us 120n + 68 = 500.

Now subtract 68 from both sides to get 120n = 432.

Dividing both sides by 120, we find that n = 3.6.

Answer:

a. 0.6975

b. 0.25

c. The events are independent and inclusive

Step-by-step explanation:

a. The proportion of five-star football recruits in the nation that go to universities in the three most competitive athletic conferences = 75%

Therefore, the probability of a five-star football recruits chooses to go to a university in the three most competitive athletic conferences p(A) = 75% or 0.75

The proportion of the times five-star football recruits get full football scholarships = 93%

Therefore, the probability that a five-star football recruit get full football scholarships p(B) = 93% or 0.93

Therefore, the probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship can be written as -the probability that a randomly selected five-star recruit who chooses one of the best three conferences and will be offered a full football scholarship is therefore;

p(A) ∩ p(B) = p(A) × p(B) = 0.75×0.93 = 0.6975

b. The probability that a randomly selected five star recruit will not select a university from one of the three best conferences = 1 - p(A) = 1 - 0.75 = 0.25

c. The events are independent as the given probability of occurrence of one event does not alter the probability of the other event

The events are inclusive events are exclusive events as P(A)and P(B) can take place simultaneously.

The correct answer is 48 pieces.

To determine the number of pieces that can be cut from the steel sheet, we need to divide the dimensions of the steel sheet by the dimensions of each piece to see how many can fit.

Calculate the number of pieces along the length:

The length of the steel sheet is given as 2400 mm, and each piece has a length of 300 mm. By dividing the total length by the length of each piece, we get 2400 mm ÷ 300 mm = 8. This means we can cut 8 pieces along the length of the steel sheet.

Calculate the number of pieces along the width:

The width of the steel sheet is given as 1200 mm, and each piece has a width of 200 mm. By dividing the total width by the width of each piece, we get 1200 mm ÷ 200 mm = 6. This means we can cut 6 pieces along the width of the steel sheet.

Calculate the total number of pieces:

To find the total number of pieces, we multiply the number of pieces along the length by the number of pieces along the width: 8 pieces × 6 pieces = 48 pieces.

Therefore, the correct answer is 48 pieces.

Answer:

This is impossible to answer, unless there is a picture that is not there.

Step-by-step explanation:

The function f(x) = x²(x + 1)² has an absolute maximum at x = -1/2, and the maximum value is 9/16.

To show that the function f(x) = x²(x + 1)² has an absolute maximum on the interval (-∞, +∞), we need to analyze its behavior and find the critical points.

(i) Critical Points:

To find the critical points, we need to find where the derivative of f(x) is equal to zero or undefined.

Taking the derivative of f(x):

f'(x) = 2x(x + 1)² + x² * 2(x + 1)

Setting f'(x) equal to zero and solving for x:

2x(x + 1)² + 2x²(x + 1) = 0

2x(x + 1)((x + 1) + x) = 0

2x(x + 1)(2x + 1) = 0

This equation is satisfied when x = 0, x = -1, or x = -1/2. These are the critical points of f(x).

(ii) Absolute Maximum:

To find the absolute maximum, we evaluate the function at the critical points and the endpoints of the interval (-∞, +∞).

Let's evaluate f(x) at the critical points and the endpoints:

f(-∞) = (-∞)²((-∞) + 1)² = +∞ (as x approaches -∞, f(x) approaches +∞)

f(-1/2) = (-1/2)²((-1/2) + 1)² = 9/16

f(-1) = (-1)²((-1) + 1)² = 0

f(0) = 0²(0 + 1)² = 0

f(+∞) = (+∞)²((+∞) + 1)² = +∞ (as x approaches +∞, f(x) approaches +∞)

From the above evaluations, we can see that the function f(x) has an absolute maximum on the interval (-∞, +∞) at x = -1/2, and the value of the maximum is f(-1/2) = 9/16.

Therefore, the function f(x) = x²(x + 1)² has an absolute maximum at x = -1/2, and the maximum value is 9/16.
