A diving board is 12.4 feet above the ground. The bottom of the pool is 16.9 feet below the ground. Choose the equation that rep

resents the situation.
A x+16.9=12.4x plus 16 point 9 is equal to 12 point 4

B x−16.9=12.4x minus 16 point 9 is equal to 12 point 4

C 16.9x=12.416 point 9 x is equal to 12 point 4

Answer:

B

29.3 feet

Step-by-step explanation:

All you need to do is add the two values together which means to do that you have to subtract something to get the other number.

The first term of a geometric sequence is 15, and the 5th term of the sequence is <img src="https://tex.z-dn.net/?f=%5Cfrac%7B24
sladkih [1.3K]

The geometric sequence is 15,9,\frac{27}{5},\frac{81}{25},  \frac{243}{125}

Explanation:

Given that the first term of the geometric sequence is 15

The fifth term of the sequence is \frac{243}{125}

We need to find the 2nd, 3rd and 4th term of the geometric sequence.

To find these terms, we need to know the common difference.

The common difference can be determined using the formula,

a_n=a_1(r)^{n-1}

where a_1=15 and a_5=\frac{243}{125}

For n=5, we have,

\frac{243}{125}=15(r)^4

Simplifying, we have,

r=\frac{3}{5}

Thus, the common difference is r=\frac{3}{5}

Now, we shall find the 2nd, 3rd and 4th terms by substituting n=2,3,4 in the formula a_n=a_1(r)^{n-1}

For n=2

a_2=15(\frac{3}{5} )^{1}

   =9  

Thus, the 2nd term of the sequence is 9

For n=3 , we have,

a_3=15(\frac{3}{5} )^{2}

   =15(\frac{9}{25} )

   =\frac{27}{5}

Thus, the 3rd term of the sequence is \frac{27}{5}

For n=4 , we have,

a_4=15(\frac{3}{5} )^{3}

    =15(\frac{27}{25} )

    =\frac{81}{25}

Thus, the 4th term of the sequence is \frac{81}{25}

Therefore, the geometric sequence is 15,9,\frac{27}{5},\frac{81}{25},  \frac{243}{125}

A simple random sample of size nequals57 is obtained from a population with muequals69 and sigmaequals2. Does the population nee
dusya [7]

Answer:

The population does not need to be normally distributed for the sampling distribution of \bar{X} to be approximately normally distributed. Because of the central limit theorem. The sampling distribution of \bar{X} is approximately normal.

Step-by-step explanation:

We have a random sample of size n = 57 from a population with \mu = 69 and \sigma = 2. Because n is large enough (i.e., n > 30) and \mu and \sigma are both finite, we can apply the central limit theorem that tell us that the sampling distribution of \bar{X} is approximatelly normally distributed, this independently of the distribution of the random sample. \bar{X} is asymptotically normally distributed is another way to state this.
