Answer:

A) The amount of change held by a teacher at the end of each day for a year.

Step-by-step explanation:

A normal distribution has a bell-shaped density curve described by its mean and standard deviation.

A) The amount of change held by a teacher at the end of each day for a year - This is probably near normal because the teacher cannot have negative cents in her or his pocket.

WXYZ is a parallelogram. Find the measure of angle Z
Delvig [45]

Given:

The figure of a parallelogram.

To find:

The measure of angle Z.

Solution:

We know that, the consecutive interior angles of a parallelogram are supplementary angles, it means there sum is 180 degrees.

In the given figure angle W and angle Z are supplementary angle. So,

m\angle W+m\angle Z=180^\circ

(18b-11)^\circ+(9b+2)^\circ=180^\circ

(27b-9)^\circ=180^\circ

(27b-9)=180

Adding 9 on both sides, we get

27b=180+9

27b=189

b=\dfrac{189}{27}

b=7

Now,

m\angle Z=(9b+2)^\circ

m\angle Z=(9(7)+2)^\circ

m\angle Z=(63+2)^\circ

m\angle Z=65^\circ

Therefore, the correct option is C.

Series are sum of a given sequence.. The sum of the given expression is -33

<h3>Sequence and series</h3>

Series are sum of a given sequence. According to the given expression

∑∑k=1 (k^2-5k-3)

Taking the sum from k = 1 to k = 4

Sum = (1-5-3) + (4-10-3) +(9-15-3)+(15-20-3)

Sum = (-7) + (-9) + (-9) + (-8)

Sum = -33

Hence the sum of the given expression is -33
