X + 2x + (x+ 2525) = 189189
4x = 186664
x = 4666
2x = 9332
x+ 2525 = 4919
Answer:
Any line passing through the origin represents a proportional relationship
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and<u> the line passes through the origin</u>
therefore
Any line passing through the origin represents a proportional relationship
Answer:
When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.
Step-by-step explanation:
Answer:
D. Both B and C
Step-by-step explanation:
The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:
5 x 10^9 /50= 0.1 * 10^9 = 1*10^8
The answer will be D since 1 x 10^8 and 100,000,000 is the same number
The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.
