Answer:

Hence the best estimate is population with correct option is 74% and

the value for x=148

Step-by-step explanation:

Given:

A sample of 200

Of which 148 prefer brand new coffee

To Find:

Which statement  is true?

Solution:

n=200

x=148

remaining 52 prefer old ones .

So  estimate population proportion,

p=x/n

p=148/200

p=0.74

p=74 %

Now, when x=52

p=x/n,

p=52/200

p=0.26

p=26%

There is no option for 52 and 24 %

Hence x=148 and p=74%.

Next, he cuts each of the pieces into three parts.

2 \div  \frac{1}{3}  = 6

Thirdly, he cuts each of the 6 pieces into 8 pieces.

6 \div  \frac{1}{8}  = 48

The diameter of a circle is 46 yards. What is the circle's circumference? d=46 yd Use 3.14 for n.​
kolbaska11 [484]

Answer:

144.44 yards

Step-by-step explanation:

The formula to find circumference is: C = π · d

Since we already have most of the factors figured out, we just replace them with what we have.

C = 3.14 · 46 yrds

144.44 = 3.14 · 46
