Answer:
<h2>475 inches</h2>
Step-by-step explanation:
You are right
Step one:
we are told that the total number of tiles is 100 in number
since each tile has a lenght of 4.75 inches each
a way to this is to add 4.75+4.75+4.75+...........................<em> in a hundred places to find the lenght.</em>
Step two:
Another way is to multiply 4.75 by 100 which is
=4.75*100= 475 in
<u>Hence the tile will cover 475 inches along the way</u>
Answer:
x = -1, y = 7
Step-by-step explanation:
8x + 3y = 13
3x + 2y = 11
Multiply the first equation by -2 and the second equation by 3. Then add them.
-16x - 6y = -26
(+) 9x + 6y = 33
--------------------------
-7x = 7
x = -1
Now substitute x = -1 in the first original equation and solve for y.
8x + 3y = 13
8(-1) + 3y = 13
-8 + 3y = 13
3y = 21
y = 7
Answer: x = -1, y = 7
The margin of error of a sample is given by:
B = z(α/2) σ/√n; where B is the margin of error = 25, z(α/2) is the level of significant = 1.96, σ is the standard deviation = 100 and n is the sample size.
25 = 1.96(100/√n)
100/√n = 25/1.96 = 12.76
√n = 100/12.76 = 7.84
n = (7.84)^2 = 61.47
Therefore, the smallest sample size required is 62 seniors.
