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.
Answer:
36 oz.
Step-by-step explanation:
If a 12 Oz soft drink is 80 cents, and we need to find out much many oz in in 2.40, we need to multiply 12 by 3.
because: 2.40=.80×3
so: 12×3= 36
2^5 ... 2 x 2 x 2 x 2 x 2
Answer:
x = 2 and y = 1
Step-by-step explanation:
A) 5x+y=11
B) x - y = 1.
(Solving by substitution)
B) x - 1 = y
A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1
6x = 12
x = 12/2. x = 2
B. 2 - 1 = y. y = 1
Answer:
x = 47°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for x
x = 180° - (31 + 102)° = 180° - 133° = 47°
