Answer:800-300
Step-by-step explanation:
since there is a 1 after the 8 it would go down to 800 and there is a 8 after the 2 so it would go up to 300
Answer:
x= -13
y= -28
Step-by-step explanation:
To find the two numbers, write a system of equations with x as one number and y as another:
x-y=15
5x=2y-9
Use substitution to substitute one equation into another. Then solve for the variable.
x=15+y into 5x=2y-9
becomes
5(15+y) = 2y-9
75+5y = 2y- 9
75+3y= -9
3y = -84
y= -28
To find x, substitute y= -28 into one equation.
x - (-28) = 15
x+28 =15
x = 15-28
x=-13
Percentage means 'out of 100 100 '. Convert the decimal number to a fraction by shifting the decimal point in both the numerator and denominator. Since there is 1 1 number to the right of the decimal point, move the decimal point 1 1 place to the right.
Answer:
41.67 % ( to 2 dec. places )
Step-by-step explanation:
Since 2 dozen cookies were baked, that is 24 and 14 were left.
Then 10 were eaten.
Calculate the percentage eaten as
percentage = 
× 100%
percentage eaten = 
× 100% ≈41.67%
Answer:
B. Events H and C are dependent and P(H|C) < P(C|H)
Step-by-step explanation:
The ratios of groups with children to hiking groups on the trail are different for the two trails.
P(H|C) = 15/45 = 1/3
P(C|H) = 15/40 = 3/8
1/3 < 3/8 so the comparison of choice B is appropriate.
