Answer:

Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.

This is the order you use when you need PEMDAS. For example, in this question:

(2 * 3) + 5(3)

First, you solve the parenthesis: 2 * 3 = 6

Next, you solve for multiplication: 5(3) = 15

Finally, you add: 6 + 15 = 21

P - Parenthesis

E - Exponents

M - Multiply

D - Divide

A - Add

S - Subtract

What does it mean in a joking way?

P - Please

E - Excuse

M - My

D - Dear

A - Aunt

S - Sally

Every 10th student was chosen from the cafeteria line to answer a question about pets. This is an example of:

Vadim26 [7]

Answer:

C)Systematic Random Sample

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this case:

Every kth element(in this exercise 10th) is systematic sample. So the answer is given by option c.

‼️‼️solve by substitution {2p-3r=6

Anestetic [448]

Answer:

#7: (p, r) = (0, -2) #8: (z,w) = z, $\frac{8}{3}$ + $\frac{4}{3}$ z), ∈R #9: (c,d) = (3,3) #10: (u,x) ∈∅ #11: (a,b) = (-1, 2) #12:

Step-by-step explanation:

Solve for 2p

2p - 3r = 6

2p = -6 -3r

substitute the given value of 2p into equation 2p - 3r = 6

-6 - 3r - 3r = 6

solve for r

r= -2

substitute value of r in equation

2p = -6 - 3x (-2)

solve for p

p=0

solution is ordered pair (p,r) = (0, -2)

Solve for w

w= $\frac{8}{3}$ + $\frac{4}{3}$ z

substitute the given value of w into equation

6 ( $\frac{8}{3}$ + $\frac{4}{3}$ z) - 8z = 16

solve for z

z ∈ R

The statement is true for any value of z and w that satisfy both equations from the system. Therefore, the solution is in parametric form.

(z,w) = z, $\frac{8}{3}$ + $\frac{4}{3}$ z)

Solve for c

c + d = 6

c = d

substitute the given value of c into equation c + d = 6

d + d = 6

solve for d

d=3

substitute value of d in equation

c=3

solution is ordered pair (c,d) = (3,3)

#10

Solve for u

u= 3-2x

substitute the given value of c into equation

2 (3-2x) +4x = -6

solve for x

x ∈∅

Since the system has no solution for x the answer is

(u,x) ∈∅

#11

Solve for b

b= 5+3a

substitute the value of b into equation

3a + 5 + 3a+ b = -1

solve for a

a= -1

substitute the value of a into equation

b= 5 + 3x (-1)

solve for b

b=2

solution is ordered pair (a, b) = (-1, 2)
