Answer:
4
Step-by-step explanation:
We have the mean, μ = 94 and standard deviation, σ = 10
We also have the number of samples, n = 36 and the confidence level, α = 95%
The formula for confidence interval is given
μ + z* (σ/√n) and μ - z* (σ/√n)
Where z* is the z-values for the confidence level
z* for 95% level of confidence is 1.96
Substitute this into the formula, we have
Upper limit ⇒ 94+(1.96)(10÷√36) = 94+(1.96)(10/6) = $97.27
Lower limit ⇒ 94 - (1.96)(10÷√36) = 94 - (1.96)(10/6) = $90.73
Answer:
Step-by-step explanation:
1/5x = 12
x = 12 × 5
x = 60
( By using transposing method )
Plz mark it as brainliest
You can recheck it by calculating
60/5= 12
