Answer:
Step-by-step explanation:
Q1:
25*20/100=5
25-5=20
answer: 5 absent and 20 present
Q2:
50*15/100=7.5
50-7.5=42.5
answer: 42.5

− 1 − 9 + ( −15) + (− 8) + 3 =
Step-by-step explanation:
− 1 − 9 + ( −15) + (− 8) + 3 [B.O.D.M.A.S rule]
= − 1 − 9 −15 − 8 + 3
= 3 - 1 - 9 - 15 - 8 (First and last subtraction)
= 3 - 33
= -30(Ans)
Answer:
-30
Step-by-step explanation:
Well we don't necessarily have to follow pemdas right now, because there is only addition and subtraction, and they are on the same level and they don't matter which order they are used in.
So, with that being said, let's go step by step. I could've done an easier way, but for the sake of this question, I will do it a way that is a bit longer.
So, -1-9= -10.
For the next number, if there is a + and then a () and there is a negative number in the parenthesis, forget about the + and just subtract 15.
-10-15= -25
Same for the next number. -25-8= -33
-33+3= -30
The easier method is just combining the negative numbers and adding/subtracting them and then combining the positive numbers and adding/subtracting them, and then combining both results to get your answer.
Anyways, hope this helped you! If so, please leave a rating and a thanks, and let me know if I was correct! (hopefully brainliest, but up to you) Have a great day!!

Expression of the collection of variables and constant. The value of the given expression 2x² - y¹ + 3x⁰ for x = 3 and y = 5 will be 16.
What is an expression?An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.
Expression is very useful to determine the end or root value of constraint.
As per the given expression,
2x² - y¹ + 3x⁰
Substitute, x = 3 and y = 5
2(3)² - 5 + 3(1) = 18 - 5 + 3 = 16.

Lines a and b are cut by transversal f. At the intersection of lines f and a, the top left angle is 96 degrees. At the intersection of lines b and f, the bottom right angle is (6 x minus 36) degrees. What must be the value of x so that lines a and b are parallel lines cut by transversal f? 10 20 22 32
Answer: 22
Step-by-step explanation:
Lines a and b are cut by transversal f.
Then from the given information,
[tex]6x-36=96[/tex] [ If two parallel lines are cut by a transversal then, the alternate exterior angles are equal. ]
[tex]\Rightarrow\ 6x=96+36\\\\\Rightarrow\ 6x=132\\\\\Rightarrow\ x=\dfrac{132}{6}\\\\\Rightarrow\ x=22[/tex]
Hence, the value of x so that lines a and b are parallel lines cut by transversal = 22

A rectangle with length 10 inches and width 5 inches. A triangle sits on top of the rectangle. The triangle has a base of 10 inches and height of 3 inches.
The area of the two shapes combined is 65 inches.
explanation:
A rectangle's formula is length x width which makes the equation 10 x 5 and the solution 50.
A triangle's formula is area = base x height ÷ 2 which makes the equation 10 x 3 ÷ 2 and the solution 15.
50 + 15 = 65

A marketing firm wants to estimate the true proportion of people in a city who use a certain brand of mobile phone. They want to produce a 90% confidence interval with a margin of error of at most 0.07. Which of the following is the smallest sample size that will produce the desired interval?
35
94
139
196
339
Answer:
139
Step-by-step explanation:
Cause it is
The smallest sample size that will produce the desired interval is 139.
Option C is the correct answer.
What is margin of error?The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.
We have,
The formula for calculating the margin of error for a confidence interval is:
Margin of error = z x (√(p x (1-p))/√(n))
where:
z = the z-score corresponding to the desired confidence level
p = the estimated proportion of the population that exhibits the behavior of interest (in this case, using a certain brand of a mobile phone)
n = sample size
We want the margin of error to be at most 0.07, which means we need to solve for the smallest possible value of n that satisfies this condition.
We also want a 90% confidence interval, which corresponds to a z-score of 1.645.
Therefore,
we have:
0.07 = 1.645 x (√(p*(1-p))/√(n))
Squaring both sides and solving for n, we get:
n = ((1.645)² x p x (1-p)) / (0.07)²
We don't know the value of p, so we need to use the worst-case scenario, which is when p = 0.5 (which gives the largest possible value of n for any given margin of error).
Plugging this into the formula, we get:
n = ((1.645)² x 0.5 x (1-0.5)) / (0.07)²
n = 138.55
Since n must be a whole number, the smallest sample size that will produce the desired interval is 139.
Therefore,
The smallest sample size that will produce the desired interval is 139.
