Part A:
Area of a circle is pi*radius^2
a=3.14*1^2
a=3.14
Part B:
Area of a rectangle is length*width
a=5*7
a=35
Part C:
Area of the shaded part would be the area of the rectangle - the area of the circle
a=35-3.14
a=31.86
What’s the mean,median, and mode of 11,14,16,15,32,23,27,27,23,43 ?
alexdok [17]
Step-by-step explanation:
mean- add all number/by the total nos
=231/10=23.1
median - the middle value of data after arranging in ascending order
11,14,15,16,23,23,27,27,32,43
therefore the median is 23
mode - is the no that has occurred more
so mode will be 23 and 27
62 percent of 80 is more
Step-by-step explanation:
the 62 percent of 80 comes out to 49.6 people and the other one comes out to 42 people
i dont know how to explain how to do it
The <em>speed</em> intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]
<h3>How to determine the range of speed associate to desired gas mileages</h3>
In this question we have a <em>quadratic</em> function of the <em>gas</em> mileage (g), in miles per gallon, in terms of the <em>vehicle</em> speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following <em>quadratic</em> function:
g = 10 + 0.7 · v - 0.01 · v² (1)
An effective approach consists in using a <em>graphing</em> tool, in which a <em>horizontal</em> line (g = 20) is applied on the <em>maximum desired</em> mileage such that we can determine the <em>speed</em> intervals. The <em>speed</em> intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].

Answer:
3v-v² = v(3-v)
Step-by-step explanation:
Use distributive property on the right side of the equality.
