Step-by-step explanation:
Please find the complete question in the attached file.
When there is a mean value k in a set of data. Otherwise, we will assert with certainty that at least one of the values is k. They can't say anything at all about the maximum or even the minimum using knowledge only. Nevertheless, we know that certain numbers cannot be over and that all numbers cannot be below than mean. Mean also no value throughout the data set must be equal.

Samuel made a list of his test scores: 88, 100, 92, 80, 85, 94, and 90. What is the lowest test score he can get on his next test to have mean score of 90?
Answers
Answer:
he needs to get a 91 to have a mean score of 90
Step-by-step explanation:
add up all the known scores to get 629
let 's' = lowest test score
(629 + s) ÷ 8 = 90 [we divide by 8 because there are 7 known and 1 unknown score)
cross-multiply to get:
629 + s = 720
s = 720-629
s = 91

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
Scientific notation is helpful when dealing with really large numbers with a lot of zeroes because you can express them with smaller numbers, and it looks a lot more simple. It's just a different way to express numbers.
Here's an example : Let's say someone asked me to put the number
650,000,000 into scientific notation.
That would be 6.5 ✕ 10^8

I need the answer find the value of x
Answers
Answer:
1. x = 126
angle POS = 33
2. x = 31
angle MOL = 118
Step-by-step explanation:
for question one, 147 degrees equals x + 21
so x = 126
147 plus 147 equals 294
360-294 equals 66
66/2 equals angle POS
angle POS = 33
for question 2, 62 degrees equals 2x
62 divided by 2 is 31
x = 31
62 + 62 = 124
360-124 = 236
236/2 = 118
angle MOL = 118

What is the value of y?
Answers
Answer:
y= 40
Step-by-step explanation:
The sum of the angle of a triangle is 180
2y+ 50 + y+10 = 180
Combine like terms
3y + 60 =180
Subtract 60 from each side
3y +60-60 = 180-60
3y = 120
Divide by 3
3y/3 = 120/3
y= 40
Answer:
y=40
Step-by-step explanation:
2y+ y+10+50=180
3y+60=180
3y=180-60
3y=12O
y=120/3
y=40

A machine depreciate in value at the rate of 10% every year on reducing balance. if the original cost is 20000 and the scrapped value is 13122, how long has the equipment been used?
Answers
Answer: 10 years
Explanation:
The original cost of the machine = 20000
The scrap value of the machine = 13122
Value of the machine = ( 20000 - 13122 ) = 6878
Depreciation of the machine for the first year = ( 6878 * 10 % )
= 687.8
So, the effective life of the machine is = ( 6878 / 687.8 )
= 10 years

Answer:
[tex] \small \sf \: x = - 12 \: \: and \: y = 10[/tex]
Step-by-step explanation:
2x + 4y = 16.
-2x - 3y = -6
Add both equation ;
[tex] \small \sf \: \: \: \: \: 2x + 4y = 16 \\ + \small \sf \: \: \underline{ -2x - 3y = -6 }\\ \small \sf \: \: \: \: \: \underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \blue{y = 10}} [/tex]
Therefore , y = 10
Substitute the value of y in the first equation
2x + 4 = 16
2 x + 4 × (10) = 16
2x + 40 = 16
subtract 40 from both side
2x + 40 - 40 = 16 - 40
2x = - 24
divide each side by 2
2x/ 2 = - 24 / 2
x = - 12
