Answer:
first we'll have to do it in order which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Step-by-step explanation:
(22÷2-2.5)+(4-6+6)
(11-2.5)+(4-6+6)
(8.5)+(4)
= 12.5
The translation is Let X,Y and Z be subsets of a universe set U, Are the following statement valid?
<h3>What is the sentence about?</h3>
Others are:
- Y-X=X UT
- Tip: Define non-empty sets and apply the relationship that is requested to verify. Or True False
Note that X,Y and Z be subsets of a universe set U and as such, the statement of Y-X=X UT is false.

Answer:
1. We have been given that a∥b , and c is neither parallel to a nor b.
Let us see which of our given options are correct.
A. m∠7 can not be equal to m∠11 as line c is not parallel to line a.
B. m∠5 can not be equal to m∠12 as line c is not parallel to line b.
C. By alternate interior angles m∠4=m∠5 as ∠4 is inside line a and ∠5 is inside line b. Both angles are on the opposite sides of transversal.
D. Since we know that corresponding angles are congruent. We can see that ∠5 corresponds to ∠1, therefore, m∠1=m∠5.
Therefore, Option C and D are correct choices.
2. We have been given that AB∥CD and m∠4=85°. We are asked to find measure of ∠5.
Since we know that same side interior angles are supplementary. In our figure we can see that ∠4 and ∠5 are same side interior angles.
Therefore, measure of ∠5 will be 95 degrees.
Step-by-step explanation:
1. is m∠4=m∠5 by the alternate interior angle theorem.
2. Angles 4 & 3 are supplementary angles or linear pair and so they have to equal 180 and 180 - 85= 95 3 & 5 are corresponding angles so 95 should be your answer.

Answer:
The median length of all pregnancies will be 266 days.
Step-by-step explanation:
We have been given that the length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days. We are asked to find the median length of all pregnancies.
We know that mean, median and mode all are equal for normal distribution.
Since we are told that the length of human pregnancies varies normally, therefore, the median length of all pregnancies will be same as mean that is 266 days.
Step-by-step explanation:
1. We we can split 4p into 9p - 5p, and now we have 3p² + 9p - 5p - 15 = 0. We can take out 3p from the first 2 terms and -5 from the last 2 terms. This gets us 3p (p + 3) -5 (p + 3) = 0. These two terms have (p + 3) as a common facor, so we can take that out as well, which give us (p + 3)(3p - 5) = ). Using Zero Product Property, p + 3 = 0 and 3p - 5 = 0, and when we solve each equation, we get p = -3, p= 5/3.
2. We will use the same process.
6x² + 14x - 3x - 7 = 0
2x (3x+7) - 1 (3x+7) = 0
(3x + 7)(2x - 1) = 0
3x + 7 = 0, 2x - 1 = 0
x = -7/3, x=1/2
Hope this helps!
