Answer: The answer is 31.25 because The mean of 16 items was found to be 30. So once you checked, it was that 2 items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Sum = mean no of items = 30 16 = 480
(32 +28) – (22 + 18) = 20
Correct mean = = 31.25

At a hospital, 56 percent of the babies born are not girls. Of the baby girls born, 12 percent are premature. What is the probability of a premature baby girl being born at this hospital? Round to the nearest percent.
5%
7%
21%
27%
Answer:
It's the first option 5%
Step-by-step explanation:
The probability of a premature baby girl being born at this hospital is,
⇒ 5%
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Now, If the likelihood of boys being born is 56%,
Then, the complement of that is the likelihood of girls being born which is,
⇒ 100% - 56% = 44%.
Since, we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl being born is:
⇒ (0.44)(0.12)
= 0.0528
⇒ 5.28%
Thus, The probability of a premature baby girl being born at this hospital is,
⇒ 5%

in the parallelogram below z=?
Answer:
z = 20
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary so
124 + 2z + 16 = 180
2z = 40
z = 20
The value of z in the given diagram is 20°.
What is a parallelogram?A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.
As per the given data:
Two adjacent angles of a parallelogram are given in the diagram.
To find the value of z:
The sum of any two adjacent sides of a parallelogram is equal to 180°.
∴ 2z + 16° + 124° = 180°
= 2z = 180° - 140°
= 2z = 40°
z = 20°
Hence, the value of z in the given diagram is 20°.

2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
Answer:
1. 9
2.
Step-by-step explanation:
1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:
640 - 30x = 370
Now, subtract both sides by 640 to get -270:
-30x = -270
Last, divide both side by -30:
-30x = 270
x = 9
Now, we know she withdraws $30 for 9 months.
2. 2 + 4(3 - 2) = x
