The ratio of chaperones to students on a field trip to New York City is 2 to 11. If there are 297 students on the trip, how many

Olenka [21]

297/11 = 27

So we have 27 groups of 11 students. If there are 2 chaperones for every 11 students, then we can do:

27x2=54

There are 54 chaperones on the field trip.

The estimated probability of a bowler getting a strike during a particular frame is 63%. If several simulations of the bowler bo

Vilka [71]

Answer: Our required probability is 39.69%.

Step-by-step explanation:

Since we have given that

Probability of a bowler getting a strike during a particular frame = 63%

Number of frames are performed = 2

We need to find the probability that the bowler would be most likely to get a strike in each of the two frames.

So, it becomes,

$\dfrac{63}{100}\times \dfrac{63}{100}=(0.63)^2\\\\=0.3969\\\\=39.69\%$

Hence, Our required probability is 39.69%.

Given the vectors u= <2, 1> and v= <5, 4>, determine the components of a vector represented by 2u - 3v

kati45 [8]

Answer:

C.) <-11, -10>

Step-by-step explanation:

Let's define how to work with vectors.

For two vectors:

V = <a, b>

W = <c, d>

The product of a scalar k and a vector is given by:

k*V = k*<a, b> = <k*a, k*b>

And the sum (or difference) of two vectors is given by:

V ± W = <a, b> ± <c, d> = <a ± c, b ± d>

Now that we know this, we can solve the problem.

Here we have the vectors:

u = <2, 1>

v = <5, 4>

then:

2u - 3*v = 2*<2, 1> - 3*<5, 4>

= <2*2, 2*1> - <3*5, 3*4>

= <4, 2> - <15, 12>

= <4 - 15, 2 - 12>

= < -11, -10>

Then the correct option is C.
