Answer:
b) 700 mg to 740 mg
Step-by-step explanation:
The mean is the sum of all the samples divided by the quantity of the samples, so a mean is a number between the maximum and the minimum sample. In this case, 720 mg must be in the interval, so letter<em> a</em> and<em> e </em>are eliminated.
The mean also represents the proportion of the samples, because the samples intend to be close to the mean. So, if 720 mg is the maximum or the minimum sample weight, it means that there are many samples close to it, and the proportion of the distribution will be small. So, letter <em>c</em> and <em>d</em> can't be the answer.
So, the largest proportion of weights is given in letter b, the interval of weights must be 700 mg to 740 mg.
√(2x+4)=16 square both sides
2x+4=256 subtract 4 from both sides
2x=252 divide both sides by 2
x=126
Answer:
-1/8
Step-by-step explanation:
The given expression is y⁻³
We want to find the value of the expression when y = -2
Thus;
At y = -2, we have; -2⁻³
According to law of exponents, x⁻⁴ = 1/x⁴
Thus; -2⁻³ = -1/2³ = -1/8

Step-by-step explanation:
(i) the area of the floor is 30m² (6m · 5m)
(ii) the perimeter of the floor is 22m (6m + 5m + 6m + 5m)
(iii) the area of the walls is:
24m² (for the 6m by 4m walls)
20m² (for the 5m by 4m walls)
88m² in total total
You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.
To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.
So 1.38 radian * 180° / 3,1416 = 79 °.
So the angle in the Column A is 2° wider than the angle in the Column B.
