The solution for the given algebraic expression is 1.
Is there any order to solve Math Operations?Yes, there is. When you solve any Math Operations, it is necessary to be attentive to the order of the solution.
First, you should solve the operation insides of Parentheses. After that priority is given to Exponents. Thereon, you can solve multiplication or division operations from left to right. Finally, addition or subtraction from left to right
See the order below

an opinion poll of 4,000 (randomly selected) voters is con- ducted. the fraction of all voters in the population with an annual income above $50,000 is 35%. what is the chance that 1,450 or more of the voters with annual incomes above $50,000 will be polled?
4.8% of voters with annual incomes over $50,000 will be polled, or at least 1,450 of them when an opinion poll of 4,000 (randomly selected) voters is con.ducted
What is probabilty ?
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
We have,
n = 4000
p = 0.35 , q=1-p=0.65
= E(X) = np= 4000 (0.35) 600 1400
6 = SE(X) = √npq √ 4000 (0-35)(0.65) = 30.1662
Consider
P(X[tex]\geq[/tex]1450) = p 7
X-U
1450 1400
30.1662
=P(z>1,66)
=0.048457
from standard normal table,
Hence, 4.845% chance that 1,450 or more of the voters with annual incomes above $50,000 will be polled

using a survey, we have obtained a large dataset of how many close friends people have. its mean is 7 and its median is 4. the variance is 100. we calculate the standard scores. what is the value of the median of the standardized dataset? group of answer choices
For the standardized dataset , the value of median = mean , which is equal to 7
The mean of the close friends people have = 7
The variance = 100
Standard deviation can be found using the formula
v = σ²
where v is the variance and
σ is the standard deviation
Then , σ² = 100
σ = √100
σ = 10
Therefore , the standard deviation for the close friends have is 10
The standard score for these vales can be found using the formula
Z = (X - μ) / σ
where Z is the standard score
X is the raw score
μ is the mean
σ is the standard deviation
Using this formula, the standard score of any raw score can be calculated.
For, the standardized dataset , the value of median will be equal to value of median.
Median = mean
Median = 7
