Answer:
The coordinates are (50, 103)
Step-by-step explanation:
The three hallways are AB, BC, CD.
The co-ordinate of D is (50, 75).
The school's flagpole is 28 meters right of the point D.
Hence the y-coordinate for the flagpole will be same as D, that is 75.
The x-coordinate will be (28 + 75) = 103.
The location of the school's flagpole will be represented by (50, 103)
Answer:
Charge Zone
Step-by-step explanation:
If Charge Zone (CZ) costs 15.80 for 20, and Electrocell batteries (EB) costs 8.10 for 10 batteries, you would find the price and quantity amount by multiplying by two. 8.10x2= 16.20, which is more than CZ.
Therefore, CZ is of better value.
The sides of the triangle would be 6 inches, 8 inches, and 9 inches long
B = 5
Because you must subtract like terms first:
B+9=14
-9 -9
= =
0 5
So, B = 5
Answer:
We fail to reject the null hypothesis that the bag filling machine works correctly at the 420 gram setting at the level of significance of 0.1. The p-value of the test statistic is 0.0250
Step-by-step explanation:
We have the following null and alternative hypothesis
vs 
lower-tail alternative.
For n = 24, 
and 
.
is normally distributed with a mean 
and a standard deviation of 
(approx). Therefore, we can use as test statistic
and the observed value is
p-value = P(Z < -1.9596) = 0.0250
We can use a table from a book or a programming language to find this probability P(Z < -1.9596).
You can use the instruction pnorm(-1.9596) in the R statistical programming language.
Because the p-value is greater than 0.1 (0.0250 > 0.1) we fail to reject the null hypothesis at the level of significance of 0.1.
