Answer:
B. The histogram appears to roughly approximate a normal distribution. The frequencies generally increase to a maximum and then decrease, and the histogram is symmetric.
Step-by-step explanation:
The Graph of Normal Distribution is like a bell-shaped. Here the value of y is less for the lower value of x and then the value of y is increased for a larger value of x, but after some time value of y is again getting decrease as the value of x increases. For the Histogram to appear to a normal distribution, the graph of histogram must have the same nature. Thus option B is only the correct option.
The histogram is made up of columns bar with no gaps between bars with different labels of numeric data of different heights shows the size of the group of different labels.
Answer:
x=4
Step-by-step explanation:
-3(4x+3)+4(6x+1)=43
distribute the -3 and 4
-12x-9+24x+4=43
combine like terms
12x-5=43
add 5 on both sides
12x=48
divide 12 on both sides
x=4
Step-by-step explanation:
y = -5/6x - 4
(0,-4) is the y intercept
the slope is -5/6, it descends 5 and goes 6 horizontally.
27 is very hard to see
28: 0.4=10
4/10=10
10/4 times 10 is 25
There are 25 students in the class
Answer:
a) The radius of the wheel is 1) more than 25.0 cm.
b) The radius of the wheel is approximately 40.925556... cm
Step-by-step explanation:
S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ =
is used to convert it. So:
θ = 
θ = 
S = rθ
25 = r 
900 = 7
r
r = 
r = 40.925556... cm
