Question attached

Answer:

130

Step-by-step explanation:

Number of students old donors can be calculated from the Pareto chart by adding number of blood donors on the different bars:

Type 0= 50

Type A= 35

Type B =30

Type AB =15

Therefore 50+35+30+15=130 blood donors

A whale is hunting at an elevation of −438 meters relative to sea level. How many meters below sea level is the whale?
Dafna1 [17]

Answer: The whale is 438 meters below the sea level.

Step-by-step explanation:

Given: A whale is hunting at an elevation of −438 meters relative to sea level.

Since in the scenario of height, a positive integer is used to represent the height (above a particular level) whereas a negative integer is used to represent the depth ( below a particular level).

If the whale is hunting at an elevation of −438 meters relative to sea level, then this means that the depth between the whale and the sea level is 468 meters.

Hence, the whale is 438 meters below the sea level.

A total of 500 voters are randomly selected in a certain precinct and asked whether they plan to vote for the Democratic incumbe
lilavasa [31]

Answer:

The limits are 0.6472 and 0.7528

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

Of the 500 surveyed, 350 said they would vote for the Democratic incumbent.

This means that n = 500, \pi = \frac{350}{500} = 0.7

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.7 - 2.575\sqrt{\frac{0.7*0.3}{500}} = 0.6472

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.7 + 2.575\sqrt{\frac{0.7*0.3}{500}} = 0.7528

The limits are 0.6472 and 0.7528

If the two legs of a right triangle measure 5 and 12 respectively, and the leg and hypotenuse of another right triangle measure
guapka [62]
They would be congruent by the side side side (s-s-s) theorem.
They are BOTH right triangles.
You have one triangle with legs = 5 and 12, by the Pythagorean Theorem, the hypotenuse would be 13.
In the other triangle, you have a leg = 12 and hypotenuse = 13.  By the Pythagorean Theorem, the other leg would be 5.
So, you have 2 triangles with sides of 5, 12 and 13 and they are congruent by the (s-s-s) theorem.
