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,

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

Naomi has earned $54 mowing lawns the past two days she works 2 and 1/2 hours yesterday and 4 1/4 hours today if Naomi is paid t

emmasim [6.3K]

She worked 2 1/2 hrs yesterday and 4 1/4 hrs today...
2 1/2 + 4 1/4 =
2 + 4 = 6
1/2 + 1/4 = 2/4 + 1/4 = 3/4
so she worked a total of 6 3/4 hrs....or 6.75 hrs

she is paid $ 54

54 / 6.75 = $ 8 per hr <=== what she earned per hr

Aron wrote the function f(x)=25x-15 find the amount of money he would make after washing x cars. Select all of the values below

hram777 [196]

Answer:

A.. 2

C.. 5

E.. 10

Step-by-step explanation:

If x represents the number of cars that wash Aron, then the domain of x must contain only integers and positive numbers (natural numbers)

This, because Aron can not wash -3 cars, it would be absurd then for x to be a negative number.

In the same way Aron can not wash 1.29 cars. Or washed 1 car or washed 2, it is not consistent in this case to say that washed a car and a half, for example.

Therefore the correct answer is the options.

A.. 2

C.. 5

E.. 10

user100 [1]

Answer:

A. a=25

B. RCA and QBD

C. Angle PBA

Step-by-step explanation:

2a-9+5a+14=180 since they are same side interior they equal 180

combine like terms- 7a+5=180

subtract 5 from each side- 7a=175

divide 7 from each side- a=25
