we are given
f(x)=[x=1]
where bracket means ceiling functions
we know that
Ceiling function returns the least value of the integer that is greater than or equal to the specified number
so, we can check each options
option-A:
At x=-4:
f(x)=[-4-1] =-5
For x<-3:
Let's assume
x=-3.1
f(x)=[-3.1-1] =[-4.1]=-5
so, this interval is TRUE
option-B:
At x=-2:
f(x)=[-2-1] =-3
For x<-1:
Let's assume
x=-1.1
f(x)=[-1.1-1] =[-2.1]=-3
so, this is FALSE
Answer:
48
Step-by-step explanation:
remember 1 dozen of something is 12 of that object
so 1 dozen cookies is 12 cookies
two dozen means two times one dozen
or 2-times twelve (because there are twelve of an object in a dozen)
2 times 12 is 24
now you double the recipe that makes 2 dozen cookies
so you have 24 cookies and you multiply that by 2 to double it and you get 48
Answer:
reflection across the x-axis
Step-by-step explanation:
32.5 percent of what number is 12.48? The answer
is 100
The value of p(a) is 0.5
Mutually exclusive events are those events that do not occur at the same time
Given,
The a and b are mutually exclusive events
P(a AND b)=0
P(a)=0.48
p(a or b)=0.98
We know that,
P(a or b)=P(a)+P(b)-P(a AND b)
P(a or b)=P(a)+P(b)-0
P(a or b)=P(a)+P(b)
P(a)=P(a or b)-P(b)
Substitute the given values
P(a)= 0.98-0.48
P(a)=0.5
Hence, the value of P(a) is 0.5
