Approximately how many women in the sample have a body temperature lower than 98 degrees fahrenheit?
1 answer:
In the sample, 15 women have body temperatures that are lesser than 98 degrees Fahrenheit.
The correct option is D.
<h3>What is Graph?</h3>In mathematics, and much more specifically through the graph theory, a chart is a structure that essentially consists of a set of objects, some of which are paired together to form "related" objects. The related pairs of vertices are known as edges, and the objects are equivalent to mathematical abstractions known as vertices.
<h3>What purposes does a graph serve?</h3>Graphs are frequently used to visually represent data relationships. Data that are too numerous or complex to be adequately described in the text and in a smaller amount of space are presented using graphs.
<h3>What do graph types mean?</h3>Graphs come in a variety of shapes and sizes, including connected and disconnected graphs, bipartite graphs, weighted graphs, directed and undirected graphs, and simple graphs.
<h3>According to the given information:</h3>As we can see in the graph:
In class limit 96-97 = 3
In class limit 97-98 = 12
Therefore, 3+12 = 15
Approximately 15 women.
In the sample, 15 women have body temperatures that are lesser than 98 degrees Fahrenheit.

Answer:
d=1.982m, t=1.019s
Explanation:
There are different approaches we can take to solve this problem. You could either solve this by using conservation of energy or by taking a kinematic approach. I'll solve this by using kinematics. So, the very first thing we need to do in order to solve this is do a drawing of the situation so we can analyze it better. (See attached picture).
So, since we are talking about an inclined plane, we can see that the force of gravity is being split into an x and y components if we incline the axis of coordinates. Taking this into account we can see that:
Since there is no friction in our system, then the only force acting upon the box is the force of gravity, or weight. Since we are taking the upwards direction as the positive direction of movement, we can say that the force of gravity is excerting a negative influence on our box, so this acceleration will be negative, so our sum of forces will now look like this:
we can cancel the masses out so we can see that:
a=-g sin(40°)
We have now enough information to solve our problem.
we can take the following equation to find the distance the block travels up the incline:
we know the final velocity must be zero, so we can use the provided data to solve our formula:
which yields:
x=1.982m
In order to find the time it takes for the block to return to its original position we can use the following formula:
since x=0 is the starting point we can use that to solve our equation:
which simplifies to:
which can now be solved for t
t(5-4.905t)=0
t=0 and 5-4.905t=0
t=0 and
so the time it takes the block to return to its original position is
t= 1.019s
