since one person equals three hours then if u have another man help him then it will take have the time = one hour and thirty minutes
Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term
can be obtained as the previous term
by a constant value called the common ratio.
![a_n=a_{n-1}.r](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D.r)
or equivalently
![a_n=a_1.r^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1.r%5E%7Bn-1%7D)
Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
Answer:
Linear Equation
Step-by-step explanation:
I cant really see the graph but i think that its linear equations because
A linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers.
So, therefore, i beleive its an linear equation
The Mean is the value of all the numbers in a data set added together and divided by the amount of numbers there are for example the mean of the set 2,5,8,9 is 6.
The median is the middle values of all the numbers. If there are 2 medians, you usually have to add them both and divide by 2 to get the actual median
The mode is the number(s) that show up the most in the data set. for example, the mode of the data set 2,2,3,4,4,4,6,9 is 4, because it is repeated 3 times.
hope this helped!
If the companies claim is to be true this statement would also be true. Since the child bag is halved in the amount of the adults, the percentage would double. There are both 15 red jelly beans in each bag. 15% of 100 is 15. 30% of 50 is 15.
