Answer:
x=35
Step-by-step explanation:
55+90=145
180-145=35
False, just because they have a same base doesn't mean they are exactly the same. Remember a cylinder has parallel bases that are congruent and a cone does not have that. <span />
Answer:
Step-by-step explanation:
Since we have given that
Number of styrofoam balls bought by Bradley in May = 48
Number of toy figurines sold in May = 19
Number of styrofoam balls bought by Lupe in June = 44
Number of toy figurines sold in June = 21
So, we need to make a matrix that represents all of their May purchases and their June sales :
So, it is given by
May June
Purchases Sales
Bradley 48 19
Lupe 49 21
Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be
The range will NOT be affected since all we're doing is shifting everything up by 0.5, which visually means the distribution curve is shifted 0.5 units to the right. The difference between the largest and smallest value will stay the same. So that's why the range stays the same at 1.4
The mean will shift by 0.5 units if we add 0.5 to each data value, so,
New mean = (old mean) + 0.5
New mean = 3.17 + 0.5
New mean = 3.67
The answer is true, because there is only one number that can be squared to twelve.
