Answer:
The number of the students who got selected are 4,13,22,31.
Step-by-step explanation:
The professor wants to select 4 students randomly.
She randomly select the fourth and every ninth student after that
First the 4th student is selected
Now by using the next term formula which is
=>a + d(n-1)
The next student is the 2nd student.
=>4 + 9(2-1)
=>4 + 9(1)
=>4 + 9
=> 13
The 3rd student will be
=>4 + 9(3-1)
=>4 + 9(2)
=>4 + 18
=> 22
The 4th student will be
=>4 + 9(4-1)
=>4 + 9(3)
=> 4+ 27
=> 31
3+7=10
55/10=5.5
5.5 x 3=16.5
5.5 x 7=38.5
16.5 : 38.5
25 + _0.10__*25
25 + __2.5___
In the 1st blank, the answer is 0.1 or 0.10 because you have to change percents to decimals to find the raise. 10% as a decimal = 0.1 or 0.10
In the 2nd blank, the answer is 2.5 because on the top, it's 0.1*25, which equals 2.5, and 2.5 is the raise. All you have to do is multiply 10%, or 0.1, by 25, and you get 2.5.
Hope this helped☺☺
.4 as a percentage is 40%
Answer:
<em>Equation of line; y = - 6x</em>
Step-by-step explanation:
As we can see from this graph, point ( 0, 0 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 0;
At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 6 / run of - 1, 6 / - 1 being a slope of - 6;
If this equation is in slope - intercept form ⇒
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
<em>Equation of line; y = - 6x</em>
