X^2 + 16x + ?
a^2 + 2ab + b
(a + b)^2 which is a perfect square.

To find b to determine the last value, you divide 16x by 2x.
so:
b = 8
the last value would be 8^2 which is 64.

Hence answer is C - 64

Four plumbers estimated the length of the radius of a cylindrical pipe. the estimates made by the plumbers are listed. • plumb
myrzilka [38]

The correct order of the radius  \sqrt{3} /11 \ , \pi /24 ,  3/25  ,  9/100 .

What is decreasing and increasing order?

A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.

The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.

For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.

Ascending order, often known as ascending order of importance, is the exact opposite of declining order.

The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.

The value of \sqrt{3} = 1.732

so \sqrt{3} / 11 = 1.732/11

=1732/11000

The value of pi = 3.14

so \pi / 24  = 3.14/24

= 314/2400

A survey shows that 10% of the population is victimized by property crime each year. A random sample of 527 older citizens (65 y
jekas [21]

Answer:

The data provide sufficient evidence that older people are more likely to be victimized.

Step-by-step explanation:

H 0 : P = 0.10

H 1 : P > 0.10 (Right tailed test)

n = 527, P = 0.1235

The test statistics

x = P - p / \sqrt{p*(1-p) / n}

x = 0.1235 - 0.10 / \sqrt{0.10 * 0.90 / 527}

x = 0.0235 / \sqrt{0.09 / 527}

x = 0.0235 / \sqrt{0.00017077798}

x = 0.0235 / 0.0130682049264618

x = 1.798257689731729

x = 1.798

P value = [1 - p(Z > 1.7980] (Right tailed test)

P value = 0.036089

The P - Value is very small, so <u>reject H0</u>

Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.
