Answer:
0.30
Step-by-step explanation:
P(x ≤ -3) = P(x=-3) + P(x=-5)
P(x ≤ -3) = 0.13 + 0.17
P(x ≤ -3) = 0.30
Find the area of the 5 sides (not 6 because the top is open).
The area is made up of a load of rectangles. 2 of each rectangle are present except the top and bottom.
(4 x 2 x 2) + (3 x 2 x 2) + (3 x 4) = 40yd²
Answer: There is a strong positive correlation between number of games won by a minor league baseball team and the average attendance at their home games is analyzed.
Step-by-step explanation:
The Pearson's coefficient 'r' gives the correlation between the predicted values and the observed values .
- It tells the direction and the strength of the relation.
- When r is negative it means there is a negative relationship between the variables .
- When r is positive it means there is a positive relationship between the variables .
- When |r|=1 , strong correlation ,
- When r=0 , there is no correlation.
- If 0.70<|r|<1 , there is a strong correlation.
- If 0.50<|r|<0.70 , there is a moderate correlation.
- If 0.30<|r|<0.50 , there is a low correlation.
Given : A regression to predict the average attendance from the number of games won has an r = 0.73.
Since r=0.73 is positive and 0.70 <0.73 <1 , it means there is a strong positive correlation between number of games won by a minor league baseball team and the average attendance at their home games is analyzed.
Given that R=130 and S=90. ST are congruent to UT so therefore U=90 and T=50
Answer: the number of terms of the series is 201 numbers
the sum of the first 20 terms is 890
the number of terms of the series is 
the series have:
u1 = 5
d = 4
=> u(n) = 5 + 4.(n - 1)
=> u(20) = 5 + 19.4 = 81
so the sum of the first 20 terms is (81 + 5).20/2 = 890
( u1 is the first number of the series, d is the distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)
