Answer:
B) X = 90
Step-by-step explanation:
If you plug in every answer choice as "X," you can easily find which answer helps the equation equal 40.
EX. 1/2 (or 0.50) times 90 plus -4 equals 41!
Equation with "X" filled in as 90 :
41 = 1/2 x 90 + (-4)!!!
Now can I get brainliest!!??
To convert temperatures in degrees Celsius to Fahrenheit multiply by 1.8 and add 32 so the paper has a typo you would multiply 25 x 1.8 = 45 + 32 = 77F so 25 C is 77 F but the way it says it we would all be dead because 25 x 8 = 200 + 32 = 232 F it would be to hot for life. So the correct answer is 77°F Hope this helps! ;D

What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94
