Answer 1

There are a few reasons thay Tammy's
sample may not be valid. Firstly, she had a
relatively small sample size, meaning that
she had a potentially large margin of error.
Additionally, she was asking students from
her math class, which could also have
created a bias simply due to the fact that
they were currently doing math. In order to
survey a more valid sample, she should
consider student of other grade levels and
from other classes to ensure that she has
the most information possible and to create
variation in her sample.

What is the range of possible sizes for side x?

Answer correctly and I will give you brainlist

Answers

0.5 < x < 16.5 given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)
Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.

16.5 given hope thus helps

Need help finding measurements on a rhombus

Answers

All of the measurements are the same because a rhombus is just a tilted square:
All sides are 4cm
Hope it helps ;)

Answer:

5. D 6. B 7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.

Answers

Answer:

-4

Step-by-step explanation:

it would be -9+5 which is basically 5-9=-4

so, the answer is -4.

Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8

Step-by-step explanation:

If it was -9°C and it INCREASED by 5°C, you need to ADD.

-9°C + 5°C

*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and make it either positive or negative, depending on which absolute value is the greatest (|9|).*

-9°C + 5°C OR |9| - |5|

|9°C| - |5°C| = |4°C| = -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)

A carpenter's tool box is made up of nails, screws, washers, and brackets in a ratio of 4:11:9:6. The total number of the pieces in the box is 60. If 5 carpenters have identical tool boxes, how many total washers are in the boxes?
A. 18
B. 48
C. 62
D. 90

Answers

Answer: D 90

Step-by-step explanation:

One way to do this follows: Find the ratio, r, which when multiplied by each of the four numbers in the ratio produces the actual number of parts present:

4r + 11r + 9r + 6r = 60

Summing these up results in 30r = 60, so r is 2.

There are 4(2), or 8, nails,

11(2), or 22, screws,

9(2), or 18, washers, and

6(2), or 12, brackets.

Note that 8 + 22 + 18 + 12 = 60 (total number of parts)

If 5 carpenters have identical boxes, there will be 5(18), or 90, total washers.

Answer:

Hank is correct

Step-by-step explanation:

With parallel lines intersected by the same line, all corresponding angles are equal. Also remember that the two angles the are formed on each line need to add to 180 degrees. So we can take the two given angle: 7x+10 and x + 10 and add them. x + 10 + 7x + 10 = 8x + 20 = 180

So Hank has the correct equation.

PLEASE SHOW ON GRAPH This introduction to forensics worksheet is designed to help you paraphrase or put reading into your own words so that when you review it later, you will understand it better and it will be easier to remember the information too! Write like you are explaining this to a 10 year old.You are to read all 8 paragraphs and then write in your own wordsName _______________________________Reading and Paraphrasing Activity 1: Ballistic Signatures and how they can be used to solve a crime:1.When lands and grooves grab and spin a projectile, or bullet, moving down the barrel of a firearm, they also create cuts in the projectile. These cuts leave behind distinctive markings that are at the heart of firearms comparisons. Lands, or ridges, refer to the high parts made when the factory makes cuts into the barrel of a firearm to make grooves, the low parts. These lands and grooves create markings known as striations on the projectile. Striations are straight and parallel to the longitudinal axis of the projectile. One can see that striations are more prevalent on soft lead bullets than they are on metal or jacketed bullets.1.My summary of the above paragraph:2.Silencers are gadgets that are designed to suppress or muffle the report of a gunshot. These can include a shirt wrapped around the barrel to a high-tech sound-absorbing screw-on attachment. Such attachments can also leave behind distinctive markings on projectiles, but these markings are not predictable. If a silencer does leave distinctive impressions on the projectile but is not available for examination by the time the forensic firearms examiner test-fires the gun, these impressions may hinder the scientists attempt to find a match between the bullet and the gun from which it was fired.2. My summary of the above paragraph: Silencers are something you put on gun so you can hide the sound of you firing it. Some people use a shirt around the barrel and some people attach a high tech screw on attachment. 3. In addition to the presence of lands, grooves, striations, and twists, each rifled barrel has minute qualities that set it apart from all others. A rifled gun barrel is the result when the manufacturer carves spiral grooves into the parietal surface of the barrel in order to make projectiles spin as they are forced down the barrel. This spinning action allows the bullet to stabilize itself during flight. This is the same physics concept with footballs as the quarterback passes the spinning ball to the receiver waiting to catch the ball down the field. For this reason, gun barrels are said to be rifled in order to promote the spinning of a bullet.3. My summary of the above paragraph:4. For the purposes of forensics, a rifling tool cuts through each metal gun barrel a bit differently. As subsequent barrels are carved out, the cutting or carving equipment becomes worn with repeated use. This progressive wear and tear creates rifling patterns that differ from one barrel to another. Furthermore, repeated firing also wears down and damages the lands and grooves. This action makes each barrel unique as well as each bullet that passes through it.4. My summary of the above paragraph: 5. In a nutshell, projectiles fired from the same firearm have the same striated patterns, but bullets fired from different ones do not. The microscopic striations found on a projectile are so unique that they are indicative that the bullet had to come from a particular gun excluding all others. This singles out one gun that sets it apart from others of the same make and model.5.
