Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

\frac{AB}{DE} = \frac{BC}{EF} , substitute values

\frac{AB}{17.64} = \frac{6.3}{13.23} ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

\frac{DF}{AC} = \frac{EF}{BC}, substitute values

\frac{DF}{4.1} = \frac{13.23}{6.3} ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61

Answer:

  21x² +20x +100 = 0

Step-by-step explanation:

We know the sum of the roots of x² +bx +c = 0 is -b, and their product is c. If the roots are α and β, then ...

  • α+β = -b
  • αβ = c

The sum of the roots of the new equation will be ...

  -b' = (α+1/β)+(β+1/α) = (α+β) +(1/α +1/β) = (α+β)(1 +1/(αβ))

The product of the roots of the new equation will be ...

  c' = (α+1/β)(β+1/α) = αβ +2 +1/(αβ)

Using the above relations for (α+β) and αβ, we find that ...

  -b' = (-b)(1 +1/c)

  c' = c + 2 + 1/c

For the given equation, our definition of b and c is ...

  b = 2/3

  c = 7/3

so the new equation has values ...

  b' = (2/3)(1 + 1/(7/3) = (2/3)(10/7) = 20/21

  c' = 7/3 + 2 + 1/(7/3) = 13/3 + 3/7 = 100/21

So, the equation with the roots of interest is ...

  x² +20/21x +100/21 = 0

Multiplying by 21 gives ...

  21x² +20x +100 = 0

Laundry detergent boxes are filled according to an approximately Normal distribution with mean 34.15 ounces and standard deviati
Leno4ka [110]

Using the normal distribution, it is found that there is a 0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

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

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

\mu = 34.15, \sigma = 0.1.

The probability a randomly selected box has less than the 34 ounces of advertised weight is the <u>p-value of Z when X = 34</u>, hence:

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

Z = \frac{34 - 34.15}{0.1}

Z = -1.5

Z = -1.5 has a p-value of 0.0668.

0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.
