Answer: B
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from to
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function =
Okay so finding the difference of 19 and 13.30, 5.70 is what we need to find when we start finding the sale percentage.
19*.15 = 2.85 (Too small!)
19*.25 = 4.75 (Not quite)
19*.30 = 5.70 (Bingo!)
The percentage off is 30%
-2 x 1 y = -1
Find the slope of this line
make y the subject
1 y = 2 x -1
Divide by 1
y = 2 x -1
Compare this equation with y=mx+b
slope m = 2
The slope of a line parallel to the above line will be the same
The slope of the required line will be 2
m= 2 ,point ( 2 , -2 )
Find b by plugging the values of m & the point in
y=mx+b
-2 = 4 + b
b= -6
m= 2
Plug value of the slope and b in y = mx +b
The required equation is y = 2 x -6
Answer:
The probability of selecting at least one consonant when selecting 2 cards is 0.0954.
Step-by-step explanation:
There are 26 letters in the English alphabet series.
Of these 26 letters there are 5 vowels and 21 consonants.
The total number of ways to select 2 letters is:
The number of ways to select at least one consonant is:
n (At least 1 consonant) = N - n (Two vowels)
Compute the probability of selecting at least one consonant as follows:
Thus, the probability of selecting at least one consonant when selecting 2 cards is 0.0954.
