Answer: v(x)=31x


Step-by-step explanation:

Given Functions: e(x)=x^2+6x+21

m(x)=8x\\\\v(x)=31x

At x=4

e(4)=(4)^2+6(4)+21\\=16+24+21=61\\\\m(4)=8(4)=32\\\\v(4)=31(4)=124

here we can see v(4) has the largest value of 124 at x=4 .

Therefore, v(x)=31x is the function which has the largest value at x=4.

e(4)=4^2+6 \times 4+21=16+24+21=61 \\ \\
m(4)=8 \times 4=32 \\ \\
v(4)=31 \times 4=124

v(x) has the largest value when x=4.

According to the empirical (69-95-99.7) rule, if a random variable z has a standard normal distribution, then approximately 95%
Dmitry_Shevchenko [17]

Using z-scores, it is found that the value of z is z = 1.96.

-----------------------------

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula, which for a measure X, in a distribution with mean \mu and standard deviation \sigma, is given by:  

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.
  • Each z-score has an associated p-value, which is the percentile.

  • The normal distribution is symmetric, which means that the middle 95% is between the <u>2.5th percentile and the 97.5th percentile</u>.
  • The 2.5th percentile is Z with a p-value of 0.025, thus Z = -1.96.
  • The 97.5th percentile is Z with a p-value of 0.975, thus Z = 1.96.
  • Thus, the value of Z is 1.96.

Solve 5× - 4 - × = 0 what is the answer
Natasha2012 [34]

Answer:

x = 1

Step-by-step explanation:

Add 4 from both sides which you add to the zero. Then, combine like terms, 5x - 1x which is 4x. Divide 4 from both sides and it equals 1.
