Answer:
0.07
Step-by-step explanation:
From the question, a given grid was divided into a definite number of squares with some of the squares shaded.
Total number of squares in the grid = 100
number of shaded squares in the grid = 7
Thus, 7 squares are shaded out of 100 square in the grid.
So that this can be expressed in fraction as;
= 
= 0.07
The decimal number of the squares represented is 0.07.
Answer:
a) 22.94 psi
b) 
Step-by-step explanation:
a)The pressure at which will trigger a warning is
31 - 31*0.26 = 22.94 psi
b) The probability that that the TPMS will trigger warning at 22.94 psi, given that tire pressure has a normal distribution with average of 31 psi and standard deviation of 2 psi
where x = 22.94, 
25% of 28 is 7 (28 x 0.25)
28 - 7 = 21
yes he would have enough money
If I understand your question well, I suppose you mean
6 + 8x, where x is a number. You can also write this in standard form as 8x + 6.
