Answer:2x^3
Step-by-step explanation:
10x^3-12x^3
2x^3(5-6)
To rotate a figure 90 degrees counter clockwise, switch the X and Y coordinates, and then multiply the new X value by -1
Find the original points:
(2,2) becomes (-2,2)
(7,1) becomes (-1,7)
(8,-4) becomes (4,8)
Answer:
See explaination
Step-by-step explanation:
We can define standard deviation in statistics as a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Answer: 2
Step-by-step explanation:
Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
90 ÷ 45 = 2
and therefore:
9 ÷ 4.5 = 2
Answer:
105 boats
Step-by-step explanation:
Let x be the total number of boats in the marina.
If Two-thirds of the boats in the marina are white.
Fraction of the remaining boat= 1-⅔ =⅓
4/7 of the remaining boats are blue.
4/7 of ⅓ are blue
4/7 X ⅓ = 4/21 are blue
Fraction of Red Boats =
1-(Proportion of white Boats +Proportion of Blue Boats)
= 1-(2/3+4/21)=1/7
If there are 15 red boats,
1/7 of the total boats =15
1/7 X x=15
x=15X7
x=105
There are 105 boats in total on the marina
