1. Find the surface area for the given prism. (11<br> 8 in.<br> 10 in.<br> 14 in,

DedPeter [7]

Answer:

SA = 664 square inches

Step-by-step explanation:

Surface area is the area of all the sides added together. A prism has six sides.

Take the dimensions and change them so each of the numbers are multiplied with the others.

14 * 10 * 8

14 * 10 = 140

14 * 8 = 112

10 * 8 = 80

Multiply each answer by 2 because there are two sides that have the same dimensions.

14 * 10 = 140 * 2 = 280

14 * 8 = 112 * 2 = 224

10 * 8 = 80 * 2 = 160

Add the areas together.

280 + 224 + 160 = 664

SA = 664 square inches

Every integer number is also a. Irrational number b. Whole number c. Natural number d. Rational number

const2013 [10]

Answer:

Option d

Step-by-step explanation:

Other options are not eligible because

a) Integers are not irrational

b)Whole numbers start from 0 and consists positive integers only.But integers consist negative integers also.

c)Natural number consists of positive integers only.

If the question had been asked as some integers are also, then options b) and c) could have been written . But in this case , it is asked every integer is also.

Thank you!

What is the difference between a ray and line segment line segment is a part of a line bound by multiple points along the line;

koban [17]

A line segment is a part of a line bound by two points; a ray is a line with one endpoint that extends to infinity in one direction. is the difference between a ray and line segment.

Option: C.

<u>Step-by-step explanation:</u>

A line is a set of multiple points that extends from one point to its opposite direction without any end. Ray and Line segments are the two parts that can occur in a line.

A ray is a line with an endpoint in which the line can be extended from that point to infinity in a direction. A line segment also another part line and it consists of two points. Moreover, The line is bounded between those points.

A simple random sample of 20 third-grade children from a certain school district is selected, and each is given a test to measur

ICE Princess25 [194]

Answer:

Option C) 5.62 points

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 20

Sample mean score = 64

Sample standard deviation, s = 12

Degree of freedom =

$=n-1\\=20-1\\=19$

We have to calculate margin of error for a 95% confidence interval.

Formula for margin of error:

$t_{critical}\times \displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.05} = \pm 2.093$

$2.093\times (\displaystyle\frac{12}{\sqrt{20}} )\\\\ =5.6161\approx 5.62$

Thus, the correct answer is

Option C) 5.62 points
