Morgan rewrote the expression 90+(10+4.8)as(90+10)+4.8 How will this change the work that is needed to evaluate the expression

Answer:

We would need to add 90+10 first instead of 10+4.8.

Step-by-step explanation:

When evaluating expressions, we follow the order of operations:

P (parentheses); E (exponents); M/D (multiplication/division from left to right); and A/S (addition/subtraction from left to right). The first thing we look for is parentheses.

When we use the associative property as Morgan did to rearrange the problem, this changes the order we begin in. It does not, however, change the answer.

Tests for tuberculosis like all other diagnostic tests are not perfect. QFT-G is one of such tests for tuberculosis. Suppose tha

Sauron [17]

Answer:

the probability of an adult getting a NEG result and truly having tuberculosis is 0.0127

Step-by-step explanation:

S = the adult really has tuberculosis.

S' = complement of S = the adult does not has tuberculosis.

POS = the test gives a positive result

P(S)= 0.05

P(POS | S)=0.746

P(NEG | S')= 0.7653

this is an intersection because the "and" word

P(NEG ∩ S) = P(NEG| S)*P(S)=(1-P(POS | S))*P(S)=(1-0.746)*0.05=0.0127

If A and B are independent events, P(A) = 0.25, and P(B) = 0.3, what is P(AB)?

Marrrta [24]

Answer:

$P(A) = 0.25, P(B= 0.3$

And if we want to find $P(A \cap B)$ we can use this formula from the definition of independent events :

$P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075$

And the best option would be:

$P(A \cap B) =0.075$

Step-by-step explanation:

For this case we have the following events A and B and we also have the probabilities for each one given:

$P(A) = 0.25, P(B= 0.3$

And if we want to find $P(A \cap B)$ we can use this formula from the definition of independent events :

$P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075$

And the best option would be:

$P(A \cap B) =0.075$

Plot a graph for the following data recorded for an object falling from rest

shusha [124]

The kind of curve obtained is linear.
The relationship between the variables is direct variation.
After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.

In this exercise, you're required to plot a graph for the data (velocity and time) recorded for an object that is falling from rest.

Based on the graph for the data (see attachment), we can logically deduce the following points:

The kind of curve obtained is linear.

The relationship between the variables is direct variation.

After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.

The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.
