Answer:
324
Step-by-step explanation:
This is because when rounding you multiply 55 by 6 that is equal to 330 which is near 324. However if you want the answer spot on it would be 294
The answer is d.61. 66+7=73. 13+8=21. 52+9=61. 10+10=20
Answer:
The area to the right of 2.120 is 0.0250 rounded to 4 decimal places
Step-by-step explanation:
We are required to find 
To find this area we have to use the t distribution. Also we can use technology like excel to find the area to the right of 2.120.
The excel function is:
=TDIST(2.120,16,1)=0.0250
Where:
2.120 is the value of the test statistic
16 is the degrees of freedom
1 denotes the one tailed.
Therefore, the area to the right of 2.120 is 0.0250
1. it is right-angled triangle because it has a 90 degree angle.
The statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
From the data given, we can calculate the correlation coefficient, slope of the line, and y-intercept.
r = 0.90
Since r is close to 1 shows a strong correlation.
Slope of the line of best fit = 437.9
Y-intercept of line of the best fit = 439.4(Refer to the attached picture)
The line will be:
y = 437.9x + 439.4
Thus, the statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4
