Answer:
12 male teachers
Step-by-step explanation:
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
A piece of wood 10 yards long
and
A piece of wood 5 feet long
He has two pieces of wood. How much does he have in all?
5+10 = 15
15 feet of wood
(6x-12)/10 factor out 2
2(3x-6)/(2(5))
(3x-6)/5 and you can factor out 3 from the numerator too
3(x-2)/5 which can be expressed as:
0.6(x-2)
Answer:
d < -5
Step-by-step explanation:
Okay, so the equation is -5(d-2)>35
First we have to use distributive property to get rid of the parenthesis.
we do -5(d) --> -5d
then, -5(-2) --> 10
So now we just redo the equation---
-5d + 10 > 35
now you have to isolate d, the variable
First, to isolate you have to get rid of 10. Subtract 10 on both sides.
-5d + 10 > 35
- 10 -10
----------------------
-5d > 25
Then you have -5d > 25. You have to do the opposite operation again to make the d by itself, so you divide -5 on each side.
-5d > 25
----- -----
-5 -5
-5d/-5 is d because the -5's cancel out. 25/-5 is -5. Now, you have to flip the equation because when working with inequalities, you have to flip the symbol.
SO,,, the answer is
d < -5

Answer:
The <em>p</em>-value of the test is 0.0512.
Step-by-step explanation:
The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
In this case the output of the t-test_ind method from scipy module is provided as follows:
Output = (-1.99, 0.0512)
The first value within the parentheses is the test statistic value.
So the test statistic value is, -1.99.
And the second value within the parentheses is the <em>p</em>-value of the test.
So the <em>p</em>-value of the test is 0.0512.
