The number 5 is 90 degrees, acute
Answer:
The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard error of the mean . The standard deviation of the sampling distribution of x overbarx, denoted sigma Subscript x overbarσx, is called the standard distribution of the sample.
Step-by-step explanation:
The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
Answer:
Step-by-step explanation:
By Inscribed Angle Theorem, the value of an inscribed angle enclosed by an arc is the half the value of that arc.
⇒ ∠RPQ = 108°/2
⇒ ∠RPQ = 54°
