Step-by-step explanation:
(a)90 by 10%
90+10% of 90=90(1+0.1)=99
(b)60 by 25%
60(1+0.25)=75
(c)80 by 75%
80(1+0.75)=140
(e)110 by 60%
110(1+0.6)=176
(f)480 by 115%
480(1+1.15)=1032
(g)140 by 45%
140(1+0.45)=203
The mean is 10,
The median is 10,
And there is no mode.
The mean of a set of numbers is the sum divided by the number of terms,
7+15+12+6+10=50
There are 5 numbers in the set,
50/5=10.
10 is the mean.
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers,
6, 7, 10, 12, 15,
10 is in the middle so it is the median.
The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Just so you don’t confuse the data with the group sets,
The actual data set is 7, 15, 12, 6, and 10
This data paired with score column or group set means that,
10 people got a score of 1-10
6 people got a score of 11-20
12 people got a score of 21-30
15 people got a score of 31-40
And 7 people got a score of 41-50 :)
Answer:
Reminder that is this form a(b)^x where a > 0
When b > 0 but < 1 that is a decay function
When b > 1 than its a growth function
Step-by-step explanation:
So following this you can figure out the answer
g(x)=0.3(x)
this is neither since there is no exponent (linear)
H=72(56)^t
this is growth since b = 56
A=(43)^t
this is growth since b = 43 ("a" is understood as "1")
H=5.9(0.82)^t
this is decay since b = 0.82
y=0.8(3.6)^t
this is growth since b = 3.6
f(t)=0.72(15)^t
this is growth since b = 14
A=49(8)^t
this is growth since b = 8
Answer:
(1, 5)
Step-by-step explanation:
When the center is the origin, the dilation factor multiplies each coordinate:
(2, 10) ⇒ (1/2)(2, 10) = (1, 5)
Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].
