Answer: The number of people can be expected to have cold = 34
Step-by-step explanation:
Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.
If a doctor sees 40 patients, then the number of people can be expected to have cold =
Hence, the number of people can be expected to have cold = 34
Answer:
Side e = 5.7
Step-by-step explanation:
Given
d = 10
f = 7
<E = 34°
Required
Calculate length of side e
This can be calculated using law of cosine as follows;
e² = d² + f² - 2 * d * f * Cos(<E)
Substitute 10 for d, 7 for f and 34 for <E. This gives
e² = 10² + 7² - 2 * 10 * 7 * cos34
e² = 100 + 49 - 140 * cos34
e² = 100 + 49 - 140 * 0.8290
e² = 100 + 49 - 116.06
e² = 32.94
Take Square Root of both sides
e = √32.94
e = 5.7 (Approximated)
<h2>
Explanation:</h2>
In this exercise, we have the following point:
Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:
As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

Step-by-step explanation:
<u>Operations With Sets</u>
Sets are a collection of elements. Some sets have elements in common with other sets. These elements are said to be in their intersection. If we know the number of elements in the set A and in the set B, and also the total number of elements in both sets, we can say
where is the total number of elements, N(A) and N(B) are the number of elements in A and B respectively, and is the number of elements in their intersection. If we wanted to know that last number, then we isolate it
Let A= Students who visited the museum of natural history
B=Students who visited the natural air and space museum
We know
Answer: 15 students visited both museums.
Note: We are assuming no students didn't visit at least one museum
