Answer:
m= 2/3
Step-by-step explanation:
Use the equation y2-y1/x2-x1
Yes because zeros have no value if they are after a decimal and have no number behind them
The answer : 4 sin c sin b sin a
Step by step
Formula = A+b+c = 180
B+c = 180-A
C+A= 180-B
A+B= 180-c
2 sin c • 2 cos a-b+c/ 2 cos a-b-c / 2
4 sin c cos 180-2b/2 cos a-(180-a)/ 2
4 sin c cos (90-b ) cos ( A-90)
4 sin c sin b sin A
Answer:
6.6
Step-by-step explanation:
For this problem, you need to add 5 to the given equation, by replacing "c" with "5"
1.8(5)-2.4
= 6.6
Answer:
Proportions have not changed significantly ( B )
Step-by-step explanation:
GIVEN DATA :
Test statistic = 4.99
significance level = 1% = 0.01
k ( number of groups ) = 3
will we use the chi-squared test to determine the degree of freedom
which is : k-1 = 3 - 1 = 2
looking at the chi-square table to determine the critical value of the test
at significance level = 0.01 and degree of freedom = 2 the critical value = 9.21
Comparing the test value ( 4.99 ) and the critical value ( 9.21 ) it can seen that the test value < critical value which is a condition for not rejecting null hypothesis of the test.
therefore we won't reject the null hypothesis
