0.40% of a number is 68
40% of n = 68

40% = \frac{40}{100} = 0.4

0.4 × n = 68

\frac{0.4n}{0.4} = \frac{68}{0.4}
n = 170

40% of 170 is 68

0.4 * x = 68
x = 68/0.4
x = 170

check:

0.4 * 170 = 68

Enter the system represented on the graph below. Find and explain the meaning of the point of intersection of the lines.
myrzilka [38]

Answer:

y = -2x+4

y = (3/2)x -3

The point of intersection is (2, 0), or x=2 and y=0.

Step-by-step explanation:

The downward-sloping line drops 2 grid squares for each 1 it goes to the right, so its slope is -2. It intersects the y-axis at +4. In slope-intercept form, its equation is ...

y = slope · x + (y-intercept)

y = -2x + 4

Similarly, the upward-sloping line rises 3 grid squares for each 2 it goes to the right, so its slope is 3/2. It intersects the y-axis at -3. Its equation is ...

y = (3/2)x -3

The two lines intersect at the point where x=2 and y=0, so the coordinates are (2, 0). These are the values of x and y that satisfy both equations, so are the solution to the system.

A company wants to compare two washing detergents (Brands A and B) to see which best keeps colors from fading. Twenty new, ident
gogolik [260]

Answer:

No, because water temperature is confounded with brand of detergent.

Step-by-step explanation:

There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.
