3 (4x + 6) = 21
4x + 6 = 21/3
4x + 6 = 7
4x = 7 - 6
4x = 1
x = 1/4
M∠ rst + m∠ vst = 180°
3 x + 7° + 9 x + 17° = 180°
12 x + 24° = 180°
12 x= 180° - 24°
12 x = 156°
x = 156° : 12
x = 13°
m ∠ rst = 3 · 13° + 7° = 39° + 7° = 46°
m ∠ vst = 180° - 46° = 134°
Answer:
A ) 46° and 134°
Answer:
1/4 goes first
Step-by-step explanation:
Answer:
A statistic is said to be unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated.
Step-by-step explanation:
A parameter is a number that describes the population.
A statistic is a number that describes a sample.
A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is exactly equal to the true value of the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn.
A statistic is biased if its expected value is not equal to the parameter.
For a. divide 125 by 300 then multiply by 100
The answer for a. is 41.66%
For b. convert percentage to decimal divide by 100 then multiply 0.15 by 2.25 to get 0.3375. Round it off to 0.34 and subtract that from 2.25 to get
The answer for b. is $1.91
For c. you have to figure out the difference first. 2.50 minus 2.00 is 0.50
So then what percent of 2.00 is 0.50
Divide 2.00 by 0.50 to get 4.
The answer for c. is 4%
Honestly this was kinda rushed because I'm in the middle of a quiz so yea hope this helps you.
