Answer:
210
Step-by-step explanation:
Your answer is 210. Assuming that the correctly formatted question is (7x10) 3, you would solve the problem like this.
First, always start with what's in parenthesis.
(7x10) = 70
Now that we have 70, we can multiply it by the remaining number, 3.
(70) 3 also known as 70x3 = 210.
If that yield sign were a equilateral triangle, then it would be a regular polygon. In that triangle, each angle would equal 120°.
Xym=yx^3
xym/xy=yx^3/yx
m=x^2
Answer: A)1/2
Step-by-step explanation: m = y2-y1/x2-x1
I will use the values (1,2) and (3,3) from the table
1=x1, 2=y1, 3=x2, 3=y2
m = 3-2/3-1
m=1/2
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
