Answer:
-1
Step-by-step explanation:
-5-15+4+15
=-20+19
=-1
Answer:
B
Step-by-step explanation:
Each histogram section represents all values from the left value, to the right value of each section (i.e the section after 10 represents all values from 10 to 20).
If we break all the weights into categories by this principle, with frequencies in parenthesis, we get;
0-10: (0)
10-20: (0)
20-30: 21, 24 (2)
30-40: (0)
40-50: 42, 47 (2)
50-60: 54, 56 (2)
60-70: 65 (1)
70-80: 72 (1)
80-90: 83, 86 (2)
90-100: (0)
with these numbers, we know for certain that the correct answer is B
Answer is C. 1205.76 m3
Just multiply 16×24×3.14.
Total - book $ - magazine $
Which is equal to:
Total + (-book $) + (-magazine $)
$35 + (-$7) + (-$5)
ANSWER: (C) $35 + (-$7) + (-$5)
Hope this helps! :)
Answer:
The function for the model that gives the pressure in atm is given as:
P = 1.000 + 0.030*D
Step-by-step explanation:
From the question, we are given the Depth with corresponding P. Our duty is to calculate the Pressure (P) in the atm given the Depth (D). From this, we know that:
1. Pressure (P) is the dependent variable, and
2. Depth (D) is the independent variable.
Hence the function is a linear relationship which is known as regression equation. This can be achieve by estimating the:
i) Slope (β), and
ii) Intercept (α).
We can obtain the slope by:
, and
.
Hence, the function is:
= α + β D
You can achieve the task through R programming. Here is the R code.
#... this code in R programming
D = c(0,33,66,99,132)
P = c(1,2,3,4,5)
mod = lm(P~D)
mod.

And we obtained P = 1.000 + 0.030 D
