Lisa [10]4 years ago

Answer:

A x=33

Step-by-step explanation:

log (3x+1) =2

Raise each side to the power of 10 to get rid of the base 10 log

10 ^log (3x+1) =10^2

3x+1 = 100

Subtract 1 from each side

3x+1-1 = 100-1

3x= 99

Divide by 3

3x/3 = 99/3

x =33

The probability that a random student at Elmville College is a freshman is 0.3; a sophomore, 0.25; and a junior or senior, 0.45.
Andre45 [30]
Let L_1 denote the event that a student is a freshman, L_2 a sophomore, L_3 a junior, and L_4 a senior.

Let E denote the event that a student majors in engineering. By the law of total probability,

\mathbb P(E)=\mathbb P(E\cap L_1)+\mathbb P(E\cap L_2)+\mathbb P(E\cap L_3)+\mathbb P(E\cap L_4)

By the definition of conditional probability, we can expand each of these intersection probabilities to get

\mathbb P(E)=\mathbb P(E\mid L_1)\mathbb P(L_1)+\mathbb P(E\mid L_2)\mathbb P(L_2)+\mathbb P(E\mid L_3)\mathbb P(L_3)+\mathbb P(E\mid L_4)\mathbb P(L_4)

\mathbb P(E)=0.15\cdot0.3+0.2\cdot0.25+2(0.3\cdot0.45)=0.365

There are 100 bacteria in a jar. Every day, the number of bacteria increases 25%. In approximately how many days will there be 5
algol [13]

Use compound interest formula

\\ \rm\Rrightarrow P(1+r/100)^t=500

\\ \rm\Rrightarrow 100(1+0.25)^t=500

\\ \rm\Rrightarrow (1.25)^t=5

\\ \rm\Rrightarrow log(1.25)^t=log5

\\ \rm\Rrightarrow tlog1.25=log5

\\ \rm\Rrightarrow t(0.097)=0.3

\\ \rm\Rrightarrow t=3.3\approx 3

Option A
