<u>Janet ⇒ 3 postcards ⇒ $1.05 </u>

Cost of postcard: 1.05/3 = $0.35

<u>Rosi ⇒ 5 postcards ⇒ $1.75 </u>

Cost of postcard: 1.75/5 = $0.35

<u>Tanya ⇒ 8 postcards ⇒ $2.80</u>

Cost of postcard: $2.80/8 = $0.35

<u>We see in all 3 cases cost of postcard is same, the cost and numbers are proportional and the relationship is:</u>

Juanita is planting a flower garden. She wants to plant 24 tulips, and twice as many daffodils as tulips. A tulip plant costs $3

slavikrds [6]

Answer:

The total cost is $\$168$

Step-by-step explanation:

Let

x-----> the number of tulips

y-----> the number of daffodils

C-----> the total cost

we know that

$x=24\ tulips$

$y=2x$

substitute the value of x

$y=2(24)=48\ daffodils$

Find the total cost

$C=3x+2y$

substitute

$C=3(24)+2(48)=\$168$

50+10(8*1)+2<br> What property do you use to solve this and how.

MissTica

You need to use PEMDAS
So first you do the parenthesis.
8*1=8.
So now re-write the problem.
50+10*8+2
Now you are going to multiply.
10*=80
Now re-write the problem again.
10+80+2
10+80=90+2=92
So the answer to this problem is 92.

The statement third, “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.

<h3>What is a survey?</h3>

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have:

A local baseball team is struggling this season, and many fans of the team believe it may be time to replace the head coach.

Number of votes V(n) = 2367

After the value of V(n) 79% of those who responded felt the coach should be fired.

Based on the data given, we can say this is referred to as voluntary response bias. The outcome exaggerates the level of support for firing the coach.

Thus, the statement third “This is voluntary response bias. The result overestimates true support for firing the coach” is correct.
