Data that can be observed with our five senses


Data that must be measured


Data that must be quantified

Answers

Answer 1

Answer:

""Data that can be observed with our five senses """is right option..

Step-by-step explanation:

A qualitative observation involves the use of five sensory organs, sight, smell, taste, touch, and hearing, and their function to examine the attributes. Being subjective in nature, it focuses on the characteristics and qualities of the variables rather than the numerical value.

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Answers

Answer:

33.11 hope this helps

Step-by-step explanation:

she needs to pay $33.108 In order to leave a 24 percent tip.

What is ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Josefina's check at Sun Bistro is $26.70. she wants to leave a 24% tip

Bill of josefina = 26.70

Bill after 24% tip = 26.70 * (1 + 24%)

Bill after 24% tip = 26.70 * 1.24

Bill after 24% tip = 33.108

Therefore, In order to leave a 24% tip she needs to pay $33.108.

Answer:

  n = 25

Step-by-step explanation:

The smallest perfect square larger than 144 = 12² is 169 = 13². As it happens, the difference of these squares is 25, a number divisible by 5.

So n=25 will make all of the expressions have values that are natural numbers.

_____

n = 0 would make all of them integers, but 0/5 = 0 is not a natural number.


Make up a data set (n = 10) that has the same minimum value, same median, and same maximum value, but a larger IQR than the boxplot shown.
a. Give your 10 numbers.
b. Give the 5-number summary for your data.
c. Describe your strategy for figuring this out.

Answers

The 10 hypothetical numbers which meets the conditions given on the question may include :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary include the maximum, minimum, lower quartile, Median and upper quartile of a distribution.

The five number summary of the hypothetical data are:

Median: 6

Minimum: 1

Maximum: 12

Lower quartile: 2.75

Upper quartile: 10

Comparing the 5 - number summary of the hypothetical data with that of the given boxplot.

From the given  boxplot shown :

Minimum value = 1

Maximum value = 12

Median = 6

LOWER QUARTILE, Q1 = 4

UPPER QUARTILE, Q3 = 8

IQR = (Q3 - Q1) = 8 - 4 = 4

THE 10 made up numbers :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary for the made up data :

Median = 1/2(n+1)th term = 5.5th term = (6+6)/2 = 6

Minimum: 1

Maximum: 12

First quartile = 1/4(n+1)th = 2.75th term = (2+3)/2 = 2.5

Third quartile: 3/4(n+1)th term = 8.25 = (10+10)/2 = 10

Interquartile Range: (10 - 2.5) = 7.5

The original data values and hypothetical data have the same minimum and maximum and median values. The hypothetical data has an higher IQR value than the original data.

y=-1

(1/2) x -1 = -1/2

3(y + 13) = 36

Distribute the 3

Subtract 39 from both sides.

3y = -3

Divide both sides by 3

y = -1

Answers

I was a little confused so I solve it two different ways and got different answers so pls read through this carefully

Substitute a+2 instead of x
That would look something like: 3(a+2)+5/a+2
Now simplify:
3a+6+5/a+2
3a+11/a+2

3(a+2) +5/(a+2)
3a+6 + 5/(a+2)
LCM: (3a(a+2) + 6(a+2) +5)/a+2
So your answer will be (3a^2 + 12a + 17)/(a+2)

I’m just going to explain how I got my answer because it might help you understand for any future problems you have like this!!

So in this case, AEB is a mirrored dilation, or for easier terms, smaller twin, of CED, so if AEB was enlarged to the same size as CED, all the angle sizes would be the same, so we have to find the dilation factor of AEB. The dilation factor is basically just how many times smaller AEB is than CED. To do this, we’re going to take a similar angle measurement from both and divide them. So, angle ABE, and angle EDC would be the same angle, so we’re going to take those measurements, so 35 divided by 18 to get 1.94. That means 1.94 would be our dilation factor. In order to find angle a, we’re going to take it’s matching angle measurement on the opposite figure, which would be angle ECD and divide that by 1.94, so 43/1.94 which would give you around 22. The actual answer was like 22.164, but I would just round to 22!! Your final answer would be A= 22 degrees!! Apologies if this is wrong, I tried my best!!
