Answer: M₂ = 0
Explanation:
HCl + NaOH — NaCl + H2O
For acid base titrations:
M₁ V₁ = M₂ V₂where lower-script 1 and 2 are the molarity and volume for acid and base respectively.
M₁ = 0.30 M
V₁ = 12.5 ml
M₂ = (unknown)
V₂ = 285
0.30 x 12.5 = 285 M₂
M₂ = 3.8/ 285
M₂ = 0
p.s I think there is an error with the typed question. It’s not possible to use 285 ml of base against 12.5 ml of acid.

Summary of Photorealism
The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. The exactness was often aided further by the use of an airbrush, which was originally designed to retouch photographs. The movement came about within the same period and context as Conceptual art, Pop art, and Minimalism and expressed a strong interest in realism in art, over that of idealism and abstraction. Among several male practitioners of Photorealism there is an interest in themes of machinery and objects of industry such as trucks, motorcycles, cars, and even gumball machines, whereas Audrey Flack, the sole female practitioner, infuses her works with greater emotionality and the transience of life. Ultimately, the Photorealists were successful in attracting a wide audience, but they are often overlooked by art historians as an important avant-garde style.

A poll worker analyzing the ages of voters found that and . what is a possible voter age that would give her zx = 1.14? round your answer to the nearest whole number. 59 66 71 90
Answer:
Option C, 71.
Explanation:
A possible voter age that would give z = 1.14 is 64 years old (rounded to the nearest whole number).
What is standard deviation?A standard deviation is a measure of how far apart the data is from the mean.
Assuming the question is asking for a possible value of the population mean age, and given that the worker found that the sample mean age is x = 65 and the sample standard deviation is s = 8.
We can calculate the standardized score (z-score) for a given population mean age using the formula:
z = (x - m) / (s / sqrt(n))
Where x is the sample mean age, m is the population mean age, s is the sample standard deviation, and n is the sample size.
To find a possible value of m that would give z = 1.14, we can rearrange the formula and solve for m:
m = x - (z x s / sqrt(n))
Putting in the given values, we get:
m = 65 - (1.14 x 8 / sqrt(100))
m = 65 - 0.91
m = 64
Therefore, a possible voter age that would give z = 1.14 is 64 years old (rounded to the nearest whole number).

Choice 1 : A-B, B-E, E-Z ;
Choice 2 : A-C, C-Z ;
Choice 3 : A-B, B-D, D-Z
when you solve for Choice 1 : A-B, B-E, E-Z:
The Distance between A-B will be = T1 = 38
The Distance between B-E will be = T4 = 67
The Distance between E-Z will be= T7 = 64
Adding them together will give you: 38 + 67 + 64 = 169
Looking at Choice 2 : A-C, C-Z:
Distance between A-C = T2 = 52
Distance between C-Z = T5 = 91
Total distance will be = 52 + 91 = 143
Solving for Choice 3 : A-B, B-D, D-Z:
The Distance between A-B = T1 = 38
The Distance between B-D = T3 = 63
The Distance between D-Z = T6 = 62
Total distance = 38 + 63 + 62 = 163
