Answer:
The probability that the temperature on a given day in February is 22º or lower is 16.7 %
Step-by-step explanation:
Given:
Average Temperature,
Standard Deviation of Temperature, [tex\sigma=8.5^{\circ}[/tex]
We have to find: Probability that the temperature is 22° or lower
.i.e., P[ X ≤ 22 ]
Let X be the Temperature on a given day in February.
We use Z-score to calculate required probability.
First we convert X into Z using this relationship,
Now, Probability [ Z ≤ -0.965 ] = 0.167272 = 16.7 %
Therefore, The probability that the temperature on a given day in February is 22º or lower is 16.7 %
15.5:1
62/4 = 15.5
15.5 : 1
Answer:
3 and 5/18
Step-by-step explanation:
lets make this easier by making them both ?/18 5 and 1/2 will become 99/18 and 4/9 will become 8/18 if every day he eat 8 of the 99 for 5 days we multiply the 8 by the 5 and thats 40, next we subtract 99 and 40, and thats 59/18 now lets divide our 59 by 18 so we can see how many whole numbers we have and that would be 3 and 5/18 so the answer is he has 3 and 5/18 left
Answer – A, B and C
Out of the four options given, the statements which are true about quadrilaterals are as follows:
A. All squares are rhombuses. (But not all rhombuses are squares)
B. All squares are rectangles (But not every rectangle is a square)
C. All rectangles are parallelograms.
Option D is wrong because trapezoids have only a pair of parallel sides while parallelograms have two pairs of parallel sides
