3 gallons of blue paint.
4qt = 1gal
12/4 = 3
25 ÷ (6 - 1) = 25 ÷ 5 = 5, she saved 5 nickels,
5 nickels = 5 × 5 = 25 cents = $0.25
5 + 25 = 30, she saved 30 dimes, 30 dimes = 300 cents = 3 dollars.
3 + 0.25 = $3.25, she saved $3.25 in all.
Answer:
C. 3.8 min < ?X - ?Y < 4.8 min
Step-by-step explanation:
Let both flares be X and Y
For X
n1 = 35
Bar x1 =19.4
D1 = 1.4
For Y
n2 = 40
Bar X2= 15.1
S2 = 0.8
√(x1²/n1) + (x2²/n2)
=√ (1.4²/35)+(0.8²+40)
= 0.2683
Critical value, t = 2.032
We now have to calculate margin of error
0.2683x2.032
= 0.545 this is approximately equal to 0.5
Bar x1 - bar X2
= 19.4 - 15.1
= 4.3
At 95% confidence level
4.3+-0.5
4.3+0.5= 4.8
4.3-0.5 = 3.8
Therefore the answer is 3.8min<X-Y<4.8min
Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
