Answer:
-3
Step-by-step explanation:
Because f(x) = y so when y=3 what is input value (x)
When y is 3 x is -3
To easily find the slope from standard form (Ax + By = C) use -A/B
1. m = -5/3
2. m = -3/5
perpendicular slopes are negative reciprocals, which these are not
parallel slopes are exactly the same, which these are also not
so, these equations are neither parallel nor perpendicular
Answer:
A. The data set would have a linear association.
C. The data set would have a positive correlation.
E. Every student earns 16 more points for each additional hour they study.
F. Students that study more tend to earn better grades on the test.
Step-by-step explanation:
Since in the question it is mentioned that the teacher obtained data with regard to the number of hours that students spent for their test and on their results. She found that on an average for each 30 minutes studied, the graded would rise by 8 points
Now this kind of relationship represents the linear association, positive correlation and study more earn better
Therefore the above three statements are true
Answer:
solution below
Step-by-step explanation:
The question says 6 working mother's were selected so <u>n = 6</u><u> </u><u>not</u><u> </u><u>0</u><u>.</u><u>6</u>
We are expected to find
P(X = 0,1,2,3,4,4,6)
1. <u>When x = 0</u>
6C0*(0.34)⁰*(0.66)⁶
= 1 *1* 0.827
= 0.0827
<u>2. When X = 1</u>
6C1*(0.34)¹*(0.66)⁵
= 6 x 0.34 x 0.252
= 0.2555
<u>3. When X = 2</u>
6C2*(0.34)²*(0.66)⁴
= 15 x 0.1156 x 0.1897
= 0.3289
<u>4. When x = 3</u>
6C3*(0.34)³*(0.66)³
20 x 0.039304 x 0.2875
= 0.2599
<u>5. When X = 4</u>
6C4*(0.34)⁴*(0.66)²
= 15 x 0.01336 x 0.4356
= 0.8729
<u>6. When x = 5</u>
6C5*(0.34)⁵*(0.66)¹
= 6 x 0.0045 x 0.66
= 0.01782
<u>7. When x = 6</u>
6C6*(0.34)⁶*(0.66)⁰
1 x 0.0015 x 1
= 0.0015
