Express the given logarithm in terms of common logarithms. Then approximate its value to four decimal places.

zhannawk [14.2K]

Answer:

3.4594

Step-by-step explanation:

To change the base of a logarithm

• $log_{b}$ x = $\frac{log_{c}x }{log_{c}b }$

where c represents the new base

Changing the base from 2 to 10

$log_{2}$ 11 = $\frac{log_{10}11 }{log_{10}2 }$ ≈ 3.4594

The table gives the relative frequencies of recipes that contains sugar and salt, contain at least one of those ingredients, or

tigry1 [53]

Answer-

The probability that a randomly selected recipe does not contain sugar, given that it contains salt is 22.4%

Solution-

The given table in the link shows the relative frequencies of recipes that contains sugar and salt, or contains at least one of those ingredients, or contains neither of those ingredients.

We have to find the conditional probability that the recipe doesn't contain sugar, given that it contains salt.

We know that, the conditional probability of occurrence of A given that B occurs is,

$P(A|B)=\frac{P(A\ and\ B)}{P(B)} =\frac{P(A\bigcap B)}{P(B)}$

$P(\text{Doesn't contain sugar}\ |\ \text{Contains salt})=\frac{P(\text{Doesn't contain sugar}\ and\ \text{Contains salt})}{P(\text{Contains salt})}$

$P(\text{Doesn't contain sugar}\ and\ \text{Contains salt})=\frac{0.15}{1} =0.15\\P(\text{Contains salt})=\frac{0.67}{1}=0.67$

Putting these values,

$P(\text{Doesn't contain sugar}\ |\ \text{Contains salt})=\frac{0.15}{0.67} =0.224=22.4\%$

1.first false because it gives 8>8, that is false , but it is written 8=8
2.false because it gives 12>8 but written -12<8
3.gives 10>8, and it is written the same true

mr yosgi has 75 papers he graded 60 of them and let a student grade the rest what percent if the papers did each person grade?

Alika [10]

He graded 60/75 papers.

If you divide these numbers instead of trying to simplify it equals the decimal 0.8.

If you move the decimal point two places to the right it's 80%.
