Answer:
The range for boys is 0-12 and the mean is 5.1
The range for girls is 2-8 and the mean is 5.3
Step-by-step explanation:
Complimentary angles add up to 90 degrees and supplementary angles add up to 180 degrees...
Complementary angle = 90-52= 38°
Supplementary angle = 180-52= 128°
Answer:
THE TOTAL INTEREST EARNED = $ 385
Step-by-step explanation:
Interest earned by sal from first account can be calculated as follows :
Principal value (P) = $1000 .
interest rate (R) = 7.5 % .
Time period (T) = 1 year .

= $ 75 .
SIMILARLY , we can find the intrest earned by rest amount.
Principal value (P) = $5000 - $ 1000 = $ 4000 .
Interest rate (R) = 7.75 % .
Time period (T) = 1 year .

= $ 310 .
THE TOTAL INTEREST EARNED = $ 75 + $ 310
= $ 385
Answer:
y = x +2
Step-by-step explanation:
4y=4x+8
Slope intercept form is
y = mx+b so we need to solve for y
Divide each side by 4
4y/4 = 4x/4 +8/4
y = x +2
The slope is 1 and the y intercept is 2
Its 8$ per hour or 8/1 hour because if you line it up every hour it increases by $8
