Solve the equation. Round to the nearest hundredth. Show work.

denis-greek [22]

Answer:

Final answer is approx x=-0.66.

Step-by-step explanation:

Given equation is $5^{-2x-1}=4^{4x+3}$ .

Now we need to solve equation $5^{-2x-1}=4^{4x+3}$ and round to the nearest hundredth.

$5^{-2x-1}=4^{4x+3}$

$\log(5^{-2x-1})=\log(4^{4x+3})$

$(-2x-1)\log(5)=(4x+3)\log(4)$

$-2x \log(5)- \log(5)=4x \log(4)+3 \log(4)$

$-2x \log(5) -4x \log(4)=3 \log(4) +\log(5)$

$x=\frac{\left(3\log(4)+\log(5)\right)}{\left(-2\log(5)-4\log(4)\right)}$

Now use calculator to calculate log values, we get:

$x=-0.65817959094$

Round to the nearest hundredth.

Hence final answer is approx x=-0.66.

Frank has a 2-digit number on his baseball uniform. The number is a multiple of 10 and has 3 for one its factors. What three num

umka2103 [35]

2 digits number

x <100 because 2digit

x/10 ∈ { 1, 2, 3, 4, 5, 6, 7, 8, 9}

x/3 ∈ {1, 2, 3, 4, 5, 6, 7, 8, 9 }

max number divide by 10 is 90
max number divided by 3 is 99

because we know that numer is divided by 10 so our collections looks like:

{10, 20, 30, 40, 50, 60, 70, 80, 90}

we look from this collections only numbers witch will divided by 3:

30, 60, 90 = this is solutions

a) we need a natural number divided by 3 and 10 lower than 100
b) i need to use lenght of number and what numbers divides them
c) as above
d) baseball, 3 and 10, 3, 30,60,90

A locker combination consists of two nonzero digits, and each combination consists of different digits. Event A is defined as ch

Troyanec [42]

The correct answer is option B which is P ( A|B) will be ( 4 / 9 ).

<h3>What is probability?</h3>

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that:-

A locker combination consists of two nonzero digits, and each combination consists of different digits. Event A is defined as choosing an odd number as the first digit, and event B is defined as choosing an odd number as the second digit.

The total sample will have 9 numbers

S = { 1,2,3,4,5,6,7,8,9} = 9

Even Number = { 2,4,6,8} = 4

Odd Number = { 1,3,5,7,9} = 5

P ( A ) = ( 4 / 9 )

P ( B ) = ( 5 / 9 )

The probability will be calculated as:-

P( A:B ) = $\dfrac{P(A)\times P(B)}{P(B)}$

P( A:B ) = $\dfrac{( 5/9 ) ( 4/9 )}{5 / 9 }$

P( A:B ) = 4 / 9

Therefore the correct answer is option B which is P ( A|B) will be ( 4 / 9 ).

Explain why the negation of “Some students in my class use e-mail” is not “Some students in my class do not use e-mail”.

Olenka [21]

Answer with Step-by-step explanation:

Since we have given that

Some students in my class use e-mail.

It is a type of 'E' statements.

Its negation should be No students in my class use e-mail.

Because if we use "Some students in my class do not use e-mail”.

It also implies some students in my class still use e-mail.

But negation contains only opposite of given statement.

So, Some students in my class do not use e-mail” is not true.
