[tex]P(X \geq 13) = 0.021[/tex]

Step-by-step explanation:

From the question we are told that:

Probability of curing patients P(x)=0.65

Sample size n=14

Generally the Binomial equation is mathematically given by

[tex]P(X) =\frac{(n!)}{X!(n-X)!))} *p^X*(1-p)^(n-X)[/tex]

Generally the equation for Equation for at least 12 cured is mathematically given by

[tex]P(X \geq 13) = P(X = 13)+P(X = 14)[/tex]

For [tex]P(X = 13)[/tex]

[tex]P(X = 13) = (14!/(13!(14-13)!))*0.65^13*(1-0.65)^(14-13) \\\\P(X = 13)= 0.018116[/tex]

For [tex]P(X = 14)[/tex]

[tex]P(X = 14) = (14!/(14!(14-14)!))*0.65^14*(1-0.65)^(14-14) \\\\P(X = 14)= 0.00240318[/tex]

Therefore

[tex]P(X \geq 13) =P(X = 13)+P(X = 14)[/tex]

[tex]P(X \geq 13) = 0.018116+0.00240318[/tex]

[tex]P(X \geq 13) = 0.02051918[/tex]

[tex]P(X \geq 13) = 0.021[/tex]

Answer:

Volume of a hexagonal pyramid = 588 square meter

Step-by-step explanation:

Given:

Base area of hexagonal pyramid = 147 square meter

Height of hexagonal pyramid = 4 meter

Find:

Volume of a hexagonal pyramid

Computation:

Volume of a hexagonal pyramid = Base area of hexagonal pyramid x Height of hexagonal pyramid

Volume of a hexagonal pyramid = 147 x 4

Volume of a hexagonal pyramid = 588 square meter

Answer:

$4

Step-by-step explanation:

Given that

total cost of 8 identical pens and 2 identical files is $32

And, the The total cost of 3 such files would be the same  as the total cost of 4 such pens

We need to find out the cost of each file

So let us assume the following things

Pens be x

File be y

Now

8x + 2y = $32 ....(1)

3y = 4x.........(2)

y =  4x÷ 3

Now put the value of y in equation 1

8x + 1.33x = 32

x = $3.55

x = $4

The cost of each file based on the given information is $4

where:

If the total cost of 8 identical pens and 2 identical files is $32, hence;

8x + 2y = 32

If the total cost of 3 such files is the same as the total cost of 4 such pens, then;

4x = 3y

From the equation

8x + 2y = 32

2(4x) + 2y = 32

2(3y) + 2y = 32

8y = 32

y = 4

Since 6=4x = 3y

4x = 3(4)

4x = 12

x= 3

Hence the cost of each file is $4

Answer:

11.06 meters

Step-by-step explanation:

Given that

The height of a regulation soccer goal is 2.4 meters

And, the distance is 10.8 meters

We need to find out the hypothesis

Here we applied the pythagoreans theorem

So,

= √ (2.4m) ^2 + (10.8 m) ^2

= √5.76 m^2 + 116.64m^2

h = 11.06 m

Hence, the hypothesis is 11.05 meters

Answer:

2x + 20 = 3x-10

2x -3x = -20-10

-x = -30

x= 30

Checking part:

2x+20 = 2(30) +20 = 60+20 = 80

3x-10 = 3(30) - 10 = 90-10 = 80

Hence, the final answer is x = 30.

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

the angle should be the same so,

2x+20=3x-10

x=30

Linear

Step-by-step explanation:

As x increases by 1, f(x) decreases at a constant rate of -5.

Since the rate is constant, the function must be linear.

Answer:

18

Step-by-step explanation:

( 3 + √3 ) ( 5 - √2 )

= 3 ( 5 - √2 ) + √3 ( 5 - √2 )

= 15 - 3√2 + 5√3 - √6

√2 = 1.41 ( approximately )

3√2

= 3 x 1.41

= 4.23

√6 = 2.44

√3 = 1.73

5√3

= 5 x 1.73

= 8.65

15 - 3√2 + 5√3 - √6

= 15 - 4.23 + 8.63 - 2.44

= 15 + 8.63 - 4.23 - 2.44

= 15 + 8.63 - 6.67

= 15 + 1.93

= 16.93

Rounding of 16.93 = 17

17 is near to 18.

So, 18 can be the answer.
