Answer:
193.2
Step-by-step explanation:
To solve the triangle:
5.2 × 6= 31.2
You would normally find half of that since it's a triangle but there are two triangles, so each would equal half of 31.2 but if you add both halves that just equals 31.2.
Square one:
9 × 6= 54
All three squares are equal since they have the same measurements.
54 + 54 + 54= 162
162 + 31.2= 193.2
Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
Here we multiply the 2nd eqation with -1 and then add both
and answer is
-6y=12
I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )
Convert mixed numbers to improper fractions 5 2/7 = 37/7:
(37/7-1 1/2) * (1- 14/53
Convert mixed numbers to improper fractions 1 1/2 = 3/2:
(37/7-3/2) * (1- 14/53
Join 37/7-3/2 = 53/14
53/14(-14/53+1)
Join 1-14/53 = 39/53
53/14 * 39/53
Cross-Cancel 53:
39/14
Your Answer As A Improper Fraction---> 39/14
Your Answer As A Mixed Number---> 2 11/14
plz mark me as brainliest :)
One is negative 4 and one is positive 2
