Answer:
The mean birth weight for the sampling distribution is
3,500 grams.
Step-by-step explanation:
The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population. If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean. This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.
Answer:
q > 5/6
Step-by-step explanation:
The LCD is (2)(3) = 6. Mult. all three terms by 6, we get:
6q - 3 > 2. Isolate q by adding 3 to both sides:
6q > 5. Then q > 5/6 (the third possible answer).
The quadratic formula
for equation
In the given case
a=1
b=-2
c=-4
Substitute in the quadratic equation
Answer:
Step-by-step explanation:
Slope-intercept form of a linear equation: y = mx + b
- m is the slope
- b is the y-intercept - when x = 0
Problem 17: y = -4x + 2
- slope: -4
- y-intercept: (0, 2)
Problem 18: y = 1/7x - 5
- slope: 1/7
- y-intercept: (0, -5)
Problem 19:
y = 1x + 3
- slope: 1
- y-intercept: (0, 3)

Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
