Answer:
x=19.998
y=3.333
Step-by-step explanation:
5x+6y=50
-x+6y=26
6y=26+x
x=26-6y
5(26-6y)+6y=50
130-30y+6y=50
130-50=30y-6y
80=24y
y= 3.333
x=26-6y
x=26-(6×3.333)
x=19.998
Answer:
The z-score is -2
Step-by-step explanation:
Here, we are asked to calculate the z-score of the height.
Mathematically, we can calculate z-score by using the formula below;
z-score = (x-mean)/SD
According to this question, mean = 44cm and SD = 3cm with x here = 38cm
Plugging these values into the z-score equation, we have
z-score = (38-44)/3 = -6/3 = -2
Answer:
I'm getting the answer 94. Don't know if that is correct though
Step-by-step explanation:
63+21 Doesn't equal negative because of absolute value. Then you add 10
246 degrees i think, 44+80= 124 then 360-124 which us 246. (i might have misunderstood the question)
The balance will be $14239.74.
_____
This is the sum of an amount ($500) accumulating interest for 25 years, and a series of $50 payments. The first amount is multiplied by (1 +.0625/4)^100, and the sum of payments is 50*((1 +.0625/4)^100 -1)/(.0625/4).
