Answer:
Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. If you see an equation with only x and y – as opposed to, say x2 or sqrt(y) – then you're dealing with a straight-line equation.
There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books. (There is, ironically, no standard definition of "standard form".)
EXPLANATION
We have that the area under the probability density curve is equal to 1.
As the width of the rectangle is 2, the height must be 1/2.
Then, the probability that X is between 0.2 and 1.54 is as follows:
P = 1/2 ( 1.54 - 0.2 )
= 0.67
Hence, the probability is 0.67
Answer:
I know this is really late but if anyone else needs help I hope this will help those people.
Step-by-step explanation: so expand (3x+5) (X-2) first apply FOIL method: (a+b) (c+d)= ac + ad +bc + bd..... a= 3x, b=5, c=x, d= -2. our end product would be 3xx+3x(-2) + 5x + 5(-2).
Then apply minus-plus rules: +(-a)= (-a)...... we would end up with 3xx-3 times 2x + 5x - 5times 2.
next simplify until we end up with 3x^2 - x- 10
Not 100% sure if this is what your looking for but this is my best educated guess from the question asked.
A power is also an exponent which is how many times you multiply a number by itself to get a product
To get 100 as a product of 10 times itself you would multiply 10x10 which is the same as 10^2
Answer:
76,
Step-by-step explanation:
If you divide 57 by 3, you get 19. If you times 19 by 4 that is the total number of students there were in all.
