Which shows two products that result in negative values​

Mathematics
1 answer:
Zanzabum3 years ago
5 0

Answer:

(2.4)(-1.8) and (0.6)(-0.4)

Step-by-step explanation:

The product of two negative numbers = a positive number. (negative × negative = positive).

Product of two positive numbers = a positive number. (Positive × positive = positive)

Product of a negative number and a positive number = a negative number. (Negative × positive = negative).

Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.

Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and

(0.6)(-0.4) = a negative value.

Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)

It is estimated that approximately 8.23% Americans are afflicted with diabetes. Suppose that a certain diagnostic evaluation for
allsm [11]

The probabilities in this problem are given as follows:

a) False positive: 0.0321 = 3.21%.

b) Diagnosed as not having diabetes: 0.8872 = 88.72%.

c) Actually has diabetes, if diagnosed as not having: 0.0019 = 0.19%.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is given as follows:

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which the parameters are described as follows:

  • P(B|A) is the probability of event B happening, given that event A happened.
  • P(A \cap B) is the probability of both events A and B happening.
  • P(A) is the probability of event A happening.

For item a, we have that:

  • 100 - 8.23 = 91.77% of the people do not have diabetes.
  • Of those, 3.5% are diagnosed with diabetes.

Hence the probability of a false positive is given as follows:

p = 0.9177 x 0.035 = 0.0321 = 3.21%.

For item b, the percentage of people who is not diagnosed as having diabetes is divided as:

  • 96.5% of 91.77% (do not have diabetes).
  • 2% of 8.23% (have diabetes).

Hence the probability is:

P(A) = 0.965 x 0.9177 + 0.02 x 0.0823 = 0.8872 = 88.72%.

For item c, we find the conditional probability, as follows:

P(A \cap B) = 0.02 \times 0.0823 = 0.001646

Then:

P(B|A) = 0.001646/0.8872 = 0.0019 = 0.19%.

Tim just took a job working for a software company. His contract states he will receive an annual salary of $61,500 and be paid
PilotLPTM [1.2K]

Answer:

$3,722.875

Step-by-step explanation:

It was stated that the $61,500 would be payed to Tim annually, therefore before we can calculate the deductions we would first have to divide the annual pay by 12 (months in a year). You would then find that Tim receives $5,125 each month. The total value of the deductions would be 21.7% ( 6.2 + 1.5 + 3 + 11 = 21.7). 21.7% of 5,125 is 1,112.125 therefore, we would subtract this value and the value for the insurance from his monthly pay to find his net paycheck per month [5,125 - (1,112.125 + 290) = $3,722.875]

How many different ways are there to rearrange the letters of the word EXAM, if you don't care if the results is a recognizable
Vlada [557]
In this case, all letters are unique.

Start by holding the first letter:
E - XAM
E - XMA
E - MAX
E - MXA
E - AXM
E - AMX
So there are 6 combinations here.

Repeat for all 4 letters.

6 x 4 = 24

This is same as 4x3x2x1.

For 3 unique characters, it is 3x2x1.
For 5 unique characters, it is 5x4x3x2x1
And so on...
