the picture in the attached figure
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
P=size of the event space/size of the sample space
step 1
find the probability that the person is over 40 years
size of the sample size=255
size of the event space=85
P=85/255------> P=1/3
step 2
find the probability that they drink root beer
size of the sample size=255
size of the event space=75
P=75/255------> P=5/17
step 3
find the probability that the person is over 40 years of age or that they drink root beer
so
P=(1/3)+(5/17)-----> P=(17*1+3*5)/51------> P=32/51-----> 0.6275----> 62.75%
therefore
the answer is
32/51 or 62.75%
-1 is correct answer because
a= -2
b= 5 then
(-2^2-5)^3
(4-5)^3
(-1)^3
-1
Any value of x makes this equation true or all real numbers
-2(3x+12) is the same this as -6x-24 when distributed
so it's -6x-24=-24-6x
her -6x just disappeared so she is wrong :)
Answer:
18 square units
Step-by-step explanation:
The distance from -2 to 7 is 9, which is the base of the rectangle. The distance from -2 to -4 is 2, which is the height of the rectangle. The formula for area of a rectangle is A=bh. 9*2=18. 18 square units is your answer.
The answer is phoenix is located at (-7,-10) it is written like this because you always have the x coordinate then the y coordinate
