Vika [28.1K]

Answer:

75%

Step-by-step explanation:

Percent yield = experimental yield / theoretical yield * 100

= 900 / 1200 * 100 (remember that 1,000 g = 1 kg)

= 75

In a data ,range is 17 and coefficient of range is 0.2 find the smallest term of the data.

anygoal [31]

Answer:

Step-by-step explanation:

Let largest value of data be L

and smallest value of data be S.

We are given that the range and coefficient of range of the data are 17 and 0.2 respectively.

Range formula is given by = Largest value - Smallest value

17 = L - S

L = 17 + S ---------- [Equation 1]

Coefficient of range formula = (Largest - Smallest) ÷ (Largest + Smallest)

0.2 = l-s/l+s

0.2 = 17/l+s

L + S = 17/0.2 = 85

So, L + S = 85

17 + S + S = 85 {using equation 1}

2*S = 80

S = 80/2 = 40

Putting value of S in equation 1, we get L = 20 + 40 = 60

Therefore, Largest value, L = 60

smallest value, S = 40

5x+6y=18and 18x-15y=36 parallel or perpendicular

Katen [24]

Answer:

They are neither parallel nor perpendicular, since slope are different and not related by any equation

Step-by-step explanation:

First arrange them according to general equation:

$y = mx + c$

for the first equation :

$5x + 6y = 18 \\ 6y = - 5x + 18 \\ { \boxed{y = - \frac{5}{6} x + 3}}$

for the second equation :

$18x - 15y = 36 \\ 15y = 18x - 36 \\ y = \frac{18}{15} x - \frac{12}{5}$
