There are two scales that may be possible for this scale model; one where it's for every foot and one where it's for every meter.
The for every foot would be better to find out since the scale would be easier to use.
First, you have to divide each sided by 4.2, since you want to find how many meters for each foot.
For every 1 foot used in the model, the actual will be 125 meters.
1 ft = 125 m
(a) d=days C=cost

4 60
C=10(d-1)+30
(b) C=10(5-1)+30
C=40+30
C=70
Any polynomial's graph cannot have two simultaneous maxima, so they must contain a minima between them. Thus, the total number of turning points of the graph is 3. Generally, when plotting a polynomial, the number of turning points is:
n = d -1; where d is the degree of the polynomial and n is the number of turning points. Thus, this function's degree must be at least 4. The answer is b.
Answer:
The test statistic is
Step-by-step explanation:
We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.
At the null hypothesis, we test if the proportion is 80%, that is:
At the alternate hypothesis, we test if the proportion is more than 80%, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
80% is tested at the null hypothesis:
This means that
A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.
This means that
The test statistic is
The test statistic is
Answer:
The answer to your question is x = 17.32; y = 8.67
Step-by-step explanation:
Process
1.- Use trigonometric functions to find x and y
a) sin Ф =
Ф = 60°
opposite side = 15
hypotenuse = ?
hypotenuse = 17.32
b) cosФ =
y = 8.67
