Answer:
92.616%
Step-by-step explanation:
Given is the data of x and y where
x = current density (mA/cm2) and
y = rate of deposition (µm/min)
to find out whether there is linear relationship between x and y
x y
20 0.14
40 1.25
60 1.71
80 2.07
r 0.962364513
r^2 0.926145457
Since r is very near to 1, we find that there is a strong positive correlation and hence linearity can be assumed
r square the coefficient of determination is 0.9261 which is 92.616%
this is the measure which accounts for variation in x due to y and or variation in y due to x.
Answer:
he has been doing it for 23 weeks
Step-by-step explanation:
$1.61 = X
7 pennies = 7 days
161/7 = 23 weeks
X = 23 weeks
3) Multiply the price of the item ($40) by the percent of the sales tax (8%). Then add that to the price of the item to get the total.
=$40 * 8%
=40 * 0.08
=$3.20 tax
=$40 price of item + $3.20 tax
=$43.20 total
5) Multiply the number of students in the band last year (36) by the percentage increased (125%).
=36 * 125%
=36 * 1.25
=45
Hope this helps! :)
Let the number of girls be g.
Let the number of boys be b.
Now we can write these equations;
3g + 4b = 92 ..........(1)
g + b = 26 ...............(2)
b = 26 - g ................(3)
Plugging the expression for b in (3) into (1), we get:
3g + 104 - 4g = 92 ......(4)
Solving (4) we get
g = 12
So the number of girls in the class is 12.
Answer: x=14
Step-by-step explanation:
Add 5 to both sides to get the x alone and get your answer.
