X is equal to 440
440/8=55
322/340=0.805
rounded to a percentage would be 81%
Linear Regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted x. the case of one explanatory variable is called simple linear regression
Answer:
B. 1/384
Step-by-step explanation:
a1=1/3
a2 = 1/6
The constant factor is 1/2
a1=2/3*1/2
a2=2/3*1/2^2
a8=2/3*(1/2)^8
2/3*1/256
Answer:
She purchased 4 pencils
Step-by-step explanation:
Here, we are to calculate the number of pencils bought given the information in the question.
The amount per pencil is $0.91. The total amount of this since she bought x number of pencils is $0.91 * x = $0.91x
Now, after paying $10, she was given $6.36 as change
what this means is that what the pencils cost is 10-6.36 = $3.64
Now we equate the cost in terms of x to this;
0.91x = 3.64
x = 3.64/0.91
x = 4 pencils
