Answer:

x=21 ways

Step-by-step explanation:

From the question we are told that:

Bike space N=7

Number of Bike n=5

Generally the equation for This combination is mathematically given by

 x=^NC_n

 x=^7C_5

 x= \frac{7!}{5!2!}

 x= 7*6/2  

 x=21 ways

My daughter is in 3rd grade. On a 3rd grade level how can she explain that 5/6 is greater than 5/8
blagie [28]
Well,5/6 is closer to one than 5/8 is,just add 1/6+5/6 and then you get 1,adding 1/8 to 5/8 is only 6/8,so that's how you can tell how it is greater! Hope this helps your daughter!

1. What does it mean that Nikoleta is in the 10th percentile for length and weight? Is that a desirable statistic if she was in
VladimirAG [237]

Explanation:

1. It means that Nikoleta is longer and heavier than 10% of children her age.

2. We generally expect that a change from being in the 50th percentile to the 10th percentile signifies a condition that is interfering with normal growth. That is not usually considered desirable.

solve the following systems of equations. Express your answer as an ordered pair in the format(a,b), with no spaces between the
kodGreya [7K]
If you multiply the top equation by -2 you get:

-4x -14y = 14 => -4x = 14+14y

now you can plug in the -4x into the second equation:

 14+14y - 3y = -19 => 11y = -33 => y=-3

Fill in y=-3 in either equation to find x:

2x - 21 = -7 => 2x = 14 => x=7

So your ordered pair is (7,-3)

PLATO !!!! Which restricted domain would allow you to define the inverse cosine function?
lawyer [7]

<u>Answer:</u>

0 ≤ x ≤ π

<u>Step-by-step explanation:</u>

In order to define the inverse cosine functions, the domains of the cosine functions are restricted.

One major condition to define an inverse of a function is that the original function must be one‐to‐one which means that one value from the domain should correspond to only one value in the range.

So we have a restriction that is placed on the values of the domain of the cosine function which is the following:

0 ≤ x ≤ π
