You have to use PEMDAS (Parentheses Exponents Multiplication/Division Addition/Subtraction) to solve this,
Because you don't have any parenthesis or exponents you start with Multiplication/Division. This means you do 4*3 to get 26+5-12
Then, you move to Addition/Subtraction in which you complete left to right, So you do 26+5 to get 31-12
Finally you subtract 31-12 to get 19
Answer:
The zeros are x=4, -2
Step-by-step explanation:
Its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.
Hope this helped!!!!
The problem ask to calculate the size of the sample space of this two-stage experiment. Base on the data given and with my calculation. I came up with an answer of that the sample space is 2 times 26 and the size if 52. I hope this helps
Step-by-step explanation:
"The probability of drawing a red ace followed by another ace of any color without replacement."
There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:
P = (2/52) (3/51)
P = 1/442
"The probability of drawing a king followed by a queen with replacement."
There are 4 kings and 4 queens. So the probability is:
P = (4/52) (4/52)
P = 1/169
"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."
There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:
P = (8/52) (8/52)
P = 4/169
"The probability of drawing a spade followed by a jack of any color with replacement."
There are 13 spades, and 4 jacks. So the probability is:
P = (13/52) (4/52)
P = 1/52
It says 20% OFF, so you would do, 1 - 0.20 = 0.80, so you would multiply 0.80 with 80 and get 64.
