Answer:

v = how many students fit into a van

b = how many students fit into a bus

School A:

11v+10b=629

School B:

14v+10b=656

Since both classes used 10 buses, we can use elimination by subtracting the A class equation from the B class equation and solve for v, for its value. Then, use either equation and the now found value for v to solve for b.

You should find part of the process to be:

14v%2B10b-%2811v%2B10b%29=656-629, which shows the van holds only a few people even before continuing the solution. (Looks like 9 students fit in a van.)

Step-by-step explanation:

If g(x)=4x-6 then g^-1(x)=? (1) -4x+6 (2)-1/4x+1/6 (3)1/4x+3/2 (4)1/4x+6

kati45 [8]

Given:

$g(x)=4x-6$

To find:

The function $g^{-1}(x)$ .

Solution:

we have,

$g(x)=4x-6$

Put g(x)=y.

$y=4x-6$

Interchange x and y.

$x=4y-6$

Isolate y.

$x+6=4y$

$\dfrac{x+6}{4}=y$

$y=\dfrac{x+6}{4}$

Substitute $y=g^{-1}(x)$ .

$g^{-1}(x)=\dfrac{x+6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{3}{2}$

Therefore, the correct option is (3).

What is the frequency of the sinusoidal graph ?

disa [49]

Answer:

The frequency of the given sinusoidal graph is 4.

Step-by-step explanation:

The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.

From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to $\frac{\pi}{2}$ .

If the complete its one cycle in $\frac{\pi}{2}$ , then the number of cycles completed by the graph in the inteval 0 to 2π is

$\frac{\pi}{2}\times frequency=2\pi$

$frequency=2\pi \times \frac{2}{\pi}$

$frequency=4$

Therefore the frequency of the given sinusoidal graph is 4.

A card is drawn from a regular deck of 52 cards and is then put back in the deck. A second card is drawn. What is the probabilit

atroni [7]

Answer:

0.5,0.25,0.125

Step-by-step explanation:

Given that a card is drawn from a regular deck of 52 cards and is then put back in the deck. A second card is drawn.

Since here we have the draws with replacement we can say each trial is independent of the other.

i.e. the first card does not affect the second card at all.

the probability that:

a) The first card is red.

= $\frac{26}{52} =0.50$

(b) The second card is hearts given that the first is red.

=P(second is hearts)

= 0.25

= $0.5*0.25\\=0.125$

(since independent)

Why would an environmental group work to discourage people from moving to florida?

pychu [463]

I think it's because of the issue of sustainability and pollution. Many companies have been expanding their business in Florida. Florida used to be one of the best producers in the US. However, because of the on-going expansion, people moving in and out of the state can lead to overpopulation and shortage on food supply. Florida is also known for its marine ecology. Expansion can also severe pollution and extinction of some animals that are found in the state
