Joe nas to take two quizzes tomorrow. He nas only enough time to study one of them. • The science quiz has 7 true-or-false quest

Nostrana [21]

Answer:

Step-by-step explanation:

Science questions are T/F. That's .5 or $\frac{1}{2}$ chance to get it right.

7 questions. Each with a $\frac{1}{2}$ .

That's $(\frac{1}{2})^{7}$

$(\frac{1}{2})^{7}$ = $\frac{1}{128}$ = .0078 = .008 rounded

English questions are multiple choice. 4 choices. That's .25 or $\frac{1}{4}$

3 questions. Each $\frac{1}{4}$

That's $(\frac{1}{4})^{3}$

$(\frac{1}{4})^{3}$ = $\frac{1}{64}$ = .0156 = .016 rounded

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

Burka [1]

Answer:

$x=-0.75$

Step-by-step explanation:

The given equation is

$4^{-5x-7}=6^{2x-1}$

We take logarithm of both sides to base 10.

$\log(4^{-5x-7})=\log(6^{2x-1})$

$(-5x-7)\log(4)=(2x-1)\log(6)$

We expand the brackets to get;

$-5x\log(4)-7\log(4)=2x\log(6)-\log(6)$

Group similar terms;

$-7\log(4)+\log(6)=2x\log(6)+5x\log(4)$

$-7\log(4)+\log(6)=(2\log(6)+5\log(4))x$

$\frac{-7\log(4)+\log(6)}{(2\log(6)+5\log(4))}=x$

$x=-0.752478$

To the nearest hundredth.

$x=-0.75$
