\\ \rm\longmapsto 2^{4x+4}=64^{x+2}

\\ \rm\longmapsto 2^{4x+4}=(2^6)^{x+2}

\\ \rm\longmapsto 2^{4x+4}=2^{6(x+2)}

\\ \rm\longmapsto 4x+4=6(x+2)

\\ \rm\longmapsto 4x+4=6x+12

\\ \rm\longmapsto 4-12=6x-4x

\\ \rm\longmapsto -8=2x

\\ \rm\longmapsto x=\dfrac{-8}{2}

Answer:

x = 1

Step-by-step explanation:

{2}^{4x + 14}  =  {64}^{x + 2}

➡️ {2}^{4x + 14}  = ( {2}^{6}  {)}^{x + 2}

➡️ {2}^{4x + 14}  =  {2}^{6x + 12}

➡️ 4x + 14 = 6x + 12

➡️ 14 - 12 = 6x - 4x

➡️ 2x = 2

➡️ x = 1

A business knew that 30%, percent of its customers were less than 25 years old. The business wanted to increase this percentage,
jeyben [28]

Answer:

The answer is "0.9258201 or \bold{ \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}}".

Step-by-step explanation:

\to P= 30 \ \%\\\\ \to  x= 18 \\\\ \to n=50\\\\\\\hat p= \frac{x}{n} = \frac{18}{50} = 0.36 \\\\\bold{Formula:}\\\\X= \frac{\hat p -p}{\sqrt{\frac{p \times (1-p)}{n}}}\\\\

    = \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times (1-0.3)}{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.21}{50}}}\\\\= \frac{0.06}{\sqrt{0.0042}}\\\\= \frac{0.06}{0.064807407}\\\\= 0.9258201

There are 20 children at a library. Six of the children have an average age of 5 years. The remaining children have an average a
Allushta [10]
Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years
14 x 8 = 112 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

Follow the process of completing the square to solve x2 - 10x + 8 = 0. How will the left side of the equation factor in step 5?
jasenka [17]

Answer:

x=5(+/-)\sqrt{17}

Step-by-step explanation:

we have

x^{2}-10x+8=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2}-10x=-8

Complete the square. Remember to balance the equation by adding the same constants to each side.

x^{2}-10x+5^{2}=-8+5^{2}

x^{2}-10x+25=-8+25

x^{2}-10x+25=17

Rewrite as perfect squares

(x-5)^{2}=17

Take square root both sides

(x-5)=(+/-)\sqrt{17}

Adds 5 both sides

x=5(+/-)\sqrt{17}
