Answer:

x=0.9

Step-by-step explanation:

1.convert to improper fractions

4x+9/7/3=3x/0.5

2.Apply fraction cross multiply

(4x+9) * 0.5=7/3 * 3x

3. simplify

(4x+9) *0.5 =7x

4.Expand

2x+4.5=7x

5.Subtract 4.5 from both sides

2x=7x-4.5

6.Subtract 7x from both sides

2x-7=7x-4.5-7x

7.Simplify

-5x=-4.5

7.Divide by -5

x=0.9

(05.01) 4^x = 8^x − 1 a. x=3/4 b. x=1 c. x=3 d. x=6 Algebra 2

Virty [35]

Answer:

c. x=3

Step-by-step explanation:

4^x = 8^(x − 1)

4 = 2^2

8 = 2^3

2^2^x = 2^3^(x-1)

We know that a^b^c = a^(b*c)

2^(2x) = 2^(3*(x-1))

2^(2x) = 2^(3x-3)

The bases are the same so the exponents are the same

2x = 3x-3

Subtract 3x from each side

2x-3x = 3x-3-3x

-x = -3

x =3

A multiple-choice examination has 15 questions, each with five answers, only one of which is correct. Suppose that one of the st

Alex

Answer:

0.0111% probability that he answers at least 10 questions correctly

Step-by-step explanation:

For each question, there are only two outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent from other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
