Multiply all the terms by the same value to eliminate fraction denominators
a/9=-4
9 . a/9=9(-4)
The dot means multiplication
Then simplify to simplify cancel the multiplied terms that are in the denominator
a=9 . -4
Multiply the number
9 . -4 =36
And don’t forget to add the negative sign so the answer is
a= -36

39 / 3/5 =
39 *5 = 195 / 3 = 65
65-39 = 26 people stayed home
Answer:
w= -9/8
Step-by-step explanation:
-1/3w -3/5 = 1/5w
+1/3w +1/3 w
-3/5=1/5w+1/3w
Make common denominators to combine like terms of the right
-3/5=1/5w+1/3w
*3 *5
-3/5=3/15w+5/15w
-3/5=8/15w
multiply both sides by the reciprocal of 8/15 which is 15/8
-3/5*15/8=8/15w*15/8
* ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
* -----> now multiply across
w= -9/8
Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
