The required mass of the solid is 8.52g. Hence option B is correct.
We have,
mb = mass/89.0, ΔTb = 2.42° C and Kb = 2.53°C•kg/mol.
<h3>What is mass?</h3>
Mass of the object is defined as the space occupied by an object.
Given equation, ΔTb=Kb x mb
2.42 = 2.53 x mb
mb =0.95
mass / 89.0 x 0.1 = 0.95
mass = 8.52 g
Thus, the required mass of the solid is 8.52g.

Answer:
The set of Real numbers
Step-by-step explanation:
x² + 4 is a parabola with the lowest point on the y-axis is 4 and continues up
-x² + 4 is a parabola with the highest point on the y-axis is 4 and continues down.
The range is the distance traveled on the y- axis.
All real numbers.
Answer:
1820
Step-by-step explanation:
X the size of the club will follow negative binomial distribution with probability of success p and number of failures r
p = 364/365, r = 5
hence E[x] = pr/(1-p) = 364/365 x 5 /(1/365) = 1820
Let's rewrite the system of equations:
y = three over four times x squared minus 3
y = (3/4) x ^ 2 - 3
y = negative three over four times x squared plus 3
y = (-3/4) x ^ 2 + 3
The system of equations is:
y = (3/4) x ^ 2 - 3
y = (-3/4) x ^ 2 + 3
The solutions are:
(-2, 0)
(2, 0)
