Many American cars feature speedometers that show kilometers per hour. If you are required to drive 500 miles, and you know that

one kilometer is approximately 5858 of a mile, how many kilometers would you cover in that journey

H(x) = 1/3x - 1 if h (15)

dalvyx [7]

Answer:

(

h

∘

f

∘

g

)

(

x

)

is known as a composite function. Here's how composite functions work:

let's say that

x

=

1

. Your function

g

(

x

)

=

1

3

(

x

)

now produces a

y

output of

1

3

, since

g

(

1

)

=

1

3

(

1

)

. Within a composite function, the y-value of one function becomes the x-value of the next, like so:

g

(

1

)

=

1

3

⇒

f

(

1

3

)

=

17

3

⇒

h

(

17

3

)

=

17

Therefore,

(

h

∘

f

∘

g

)

(

1

)

=

17

Based on this, to find the function for

(

h

∘

f

∘

g

)

(

x

)

(combined from right to left, by the way), simply replace

x

in

f

(

x

)

with the function

g

(

x

)

, and replace

x

in

h

(

x

)

with the function of

(

f

∘

g

)

(

x

)

, to get

(

h

∘

f

∘

g

)

(

x

)

.

This, simplified, is equal to

2

x

+

15

, and therefore

(

h

∘

f

∘

g

)

(

1

)

=

2

(

1

)

+

15

=

17

Suppose that the handedness of the last fifteen U.S. presidents is as follows:40% were left-handed (L)47% were Democrats (D)If a

lesantik [10]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Probability that they were left handed P(L)= 40%

Probability that they were Democrats P(D)= 47%

So, P(L∩D) = 135 = 0.13

Now, to check whether they are independent or not.

We will find P(L) × P(D) is given by

$P(L)\times P(D)=0.47\times 0.40=0.188$

Since P(L) . P(D) ≠ P(L∩D)

So, they are not independent.

Hence, Option 'c' is correct.

Is this multiplication? Can you also help me with the answer!?

Answer:

84,375 m^2

Step-by-step explanation:

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).

Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.

Area of a square is length times width.

Total area = $4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2$
