40 because if you multiply 2 by 100 it is 200 then divide that by 5 and you get 40
Answer:
The best estimate is 32 out of 32 times, she will be early to class
Step-by-step explanation:
The probability of being early is 99% = 99/100 = 0.99
So out of 32 classes, the best estimate for the number of times she will be early to class will be;
0.99 * 32 = 31.68
To the nearest integer = 32
under a rotation about the origin of 180°
a point (x, y ) → (- x, - y )
hence D is correct, both the x and y coordinates of the points on ΔA'B'C' have opposite signs from the corresponding points on ΔABC
Answer:
Therefore Lateral Area of Cone is 189.97 yd².
Step-by-step explanation:
Given:
Slant height = 12.1 yd
Diameter = 10 yd
∴ Radius = half of Diameter = 10 ÷ 2 = 5 yd
To Find:
Lateral Area of Cone = ?
Solution:
We know that,
Substituting the given values we get
Therefore Lateral Area of Cone is 189.97 yd².
Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
