A) Divide the total height by the average height:
26.4 / 1.2 = 22 total boys.
B) Divide total feet by total time:
440 feet / 20 seconds = 22 feet per second.\
Because the submarine is diving the rate would become negative 22 feet per second.
Angle A and Angle D are congruent because angles of an equilateral triangle are congruent.
Side AD is equal to side AD because of the reflexive property
Side AC is congruent to side DB because components of sides are congruent
Therefore, Triangle ACD is congruent to Triangle DBA

Question:
The sample mean foot length of a simple random sample of 25 third-graders is 22.5 cm. The standard error of the mean is 0.8 cm. Which one of the following is a correct interpretation for the standard error of the mean?
The typical distance between each individual foot length in the sample and the sample mean foot length is approximately 0.8 cm.
The typical distance between one sample mean foot length and another sample mean foot length is 0.8 cm.
The typical distance between each individual foot length in the population and the true mean foot length is approximately 0.8 cm.
The typical distance between means of samples of size 25 and the population mean foot length is approximately 0.8 cm
The typical distance between each individual foot length in the sample and the true mean foot length is approximately 0.8 cm.
Answer:
The correct option is:
The typical distance between means of samples of size 25 and the population mean foot length is approximately 0.8 cm
Step-by-step explanation:
The standard error of the mean is a measure of the extent of variation of the mean in a sample of data from that of the value of the mean within the general population. It is a statistical measure of the probability that the size of a particular sample will approach that of the population mean, with reference to the principle of the central limit theorem.
Therefore, the interpretation of the standard error is that the variation between mean in a sample of 25 and that of the population is about 0.8 cm.
Answer:
y = 5x + 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 6, - 2) into the partial equation
- 2 = - 30 + c ⇒ c = - 2 + 30 = 28
y = 5x + 28 ← equation of line
