Answer: 26.6
Step-by-step explanation:
r = 12 5(12) = 60 | s = 4 8.35(4) = 33.4 | Now subtract both total number = 33.4 - 60 = 26.6
Answer:
MZA = 140
Step-by-step explanation:
5x+25°+ x + 17°=180°(Supplimentary Angles)
6x + 42° =180°
6x =180 - 42
6x=138
(divide by 6 both sides)
X= 23
substitution X into the given angle
5x +25
5(23)+25
115+25
140
Since this question is asking for the unit rate of the cost per yard of fabric, think of this as a ratio and proportions question where 2.6:8.94 = 1:x (represents the cost per yard).
To solve, cross multiply to get 2.6x=8.94
Then, solve for x and you get about $3.44 per yard
Answer: E. All of the above statements are true
Step-by-step explanation:
The mean of sampling distribution of the mean is simply the population mean from which scores were being sampled. This implies that when population has a mean μ, it follows that mean of sampling distribution of mean will also be μ.
It should also be noted that the distribution's shape is symmetric and normal and there are no outliers from its overall pattern.
The statements about the sampling distribution of the sample mean, x-bar that are true include:
• The sampling distribution is normal regardless of the shape of the population distribution, as long as the sample size, n, is large enough.
• The sampling distribution is normal regardless of the sample size, as long as the population distribution is normal. • The sampling distribution's mean is the same as the population mean.
• The sampling distribution's standard deviation is smaller than the population standard deviation.
Therefore, option E is the correct answer as all the options are true.
Answer:
6 meters
Step-by-step explanation:
Every 7 floors, it goes up by 22.4 meter intervals.
Let's count down,
the 7th floor would be 50.8 - 22.4, which is 28.4.
the 0th floor would be 28.4 - 22.4, which is 6.
