Answer:
2.02 i think
Step-by-step explanation:
Mass = 100 g
Volume = 50 cm³
Density :
D = m / V
D = 100 / 50
D = 2 g/cm³
answer A

Answer:
Julia found 5 coins
Step-by-step explanation:
lets take the # of coins julia found as "x"
alice found6
davi found 5
lucas found 6
and carter found 8
remember how to calculate mean( add all numbers and divide by the# of numbers)
so
6+5+6+8+x/5=6 (since there are "5" terms)
so
25+x/5=6
treat this like a linear equation so multiply by 5 on both sides
25+x/5(5)=6(5)
25+x=30
subtract "25 on both sides"
25-25+x=30-25
x=5
hope this helps
Um,
We know that the total interior angle in this parallelogram is 360° because there is the formula that help you with it:
180°(n-2) where n represent the total side of the figure, so
180°(4-2)
=180°(2)
=360°
Next, We see that angle L and angle N are equal with each other, and so angle O and M. Now, we have this equation:
(x+40°)+(x+40)°+(3x)°+(3x)°=360°
x°+40°+x°+40°+3x°+3x°=360°
8x°+80°=360°
Subtract 80° for both side
8x°+80°-80°=360°-80°
8x°=280°
x=35°
Angle O:
3x°
=3(35)°
=105°. As a result, angle O is 105°. Hope it help!
Answer:
The sets could be 5, 5, 5, 5, 5 and 0, 10, 20, -10, 5
Step-by-step explanation:
Standard deviations are a measure of how far the average point is away from the mean. In the first example, each term is exactly the mean. In the second set, some are quite a distance from the mean and therefore, it would have a bigger standard deviation.
