Answer:
2
Step-by-step explanation:
4x3=(-2)x5:(-7)
12=-2x5
12=10
12-10=0
ans=2
Step-by-step explanation:
Vicky Bought:
Strawberries $3.50
Carrots $2.25
Flowers $9.95
Subtotal $3.50 + $2.25 + $9.95
= $15.70
5% Sales Tax (5% of Subtotal) = 5/100 x $15.70
= $0.785 (will not round off here as it is not the final answer.)
Total = Subtotal + 5% Sales Tax
= $15.70 + $0.785
= $16.485
= $16.49 (rounded off to nearest cent)
Answer: 1.88
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Significance level : 
Critical value : 
By using the standard normal distribution table for z, we find the critical value of 
corresponds to the p-value 0.03.
Hence, the z-value that was used in the computation must be 1.88 .
The answer is 24 if I'm right
Answer:
4 y = -4 x + 8 or y = -x + 2
y - x = -2 or y = x - 2
using the standard form for a line y = m x + b
We see that in one equation m = -1 and in the other m' = +1
this is the condition for perpendicular lines
