Complementary angles are 90 degrees
Supplementary angles are 180 degrees.
you add two angles and they have to equal either 90 or 180 in order to be complementary or supplementary.
the answer is B because <SXT is 25 and <TXU is 65. when you add those two, the answer is 90.
Answer:
1. 30/14
2. -26.775
3. 0.1668
4. -44/7 which can be simplified into -6 and -2/7
5. $10.96
Answer:
1/29
Step-by-step explanation:
There are 29 students in total, and the students with blue eyes is only 1.
The fraction would be 1/29 and this is its simplest form.
Answer:
532.52
Step-by-step explanation:
P 2(10-inch pizza)=407*3.72-358*0.49=1514.04-175.42=1339.62
P2(12-inch pizza)=169*5.26-142*0.04=888.94-5.68=883.26
P=1339.62+883.26=2222.88
2222.88-1690.36=532.52
Answer:
Step-by-step explanation:
Hello!
Given the variables
Y: standardized history test score in third grade.
X₁: final percentage in history class.
X₂: number of absences per student.
<em>Determine the following multiple regression values.</em>
I've estimated the multiple regression equation using statistics software:
^Y= a + b₁X₁ + b₂X₂
a= 118.68
b₁= 3.61
b₂= -3.61
^Y= 118.68 + 3.61X₁ - 3.61X₂
ANOVA Regression model:
Sum of Square:
SS regression: 25653.86
SS Total: 36819.23
F-ratio: 11.49
p-value: 0.0026
Se²= MMError= 1116.54
Hypothesis for the number of absences:
H₀: β₂=0
H₁: β₂≠0
Assuming α:0.05
p-value: 0.4645
The p-value is greater than the significance level, the decision is to not reject the null hypothesis. Then at 5% significance level, there is no evidence to reject the null hypothesis. You can conclude that there is no modification of the test score every time the number of absences increases one unit.
I hope this helps!
