Answer:
32.10
Step-by-step explanation:
7% = 0.07
30 x 0.07=2.10
30+ 2.10=32.10
Price before Taxes: $ 30.00
+ Sales Tax (7%): $ 2.10
Total Price with Tax: $ 32.10
Answer:
15.4
Step-by-step explanation:
sin 17° = 4.5 /x
x = 4.5 / sin 17° = 4.5 /0.2924
= 15.4
Answer: 0.2643
Step-by-step explanation:
Let p be the population proportion and 
be the sample proportion .
As per given question , we have
z-score : 
The required probability ( using z-table ):-
Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643
Answer: D. y = -4x + 4
Step-by-step explanation:
Notice that the y-intercept is when x is zero and the x intercept is when y is 0.
and to write in the equation in slope intercept form , you will need the slope and the intercept.
We will use the y and x intercepts to find the slope, by find the difference in their y coordinates and dividing it by the difference in their x coordinates.
y intercept: ( 0,4)
x intercept: (1,0)
y coordinates difference: 4 - 0 = 4
x coordinates difference: 0 - 1 = - 1
Slope: 4/-1 = -4
Since the slope is -4 and the the y intercept is 4 , the equation will be
y = -4x + 4
