Answer:
144 boys and 384 girls
Step-by-step explanation:
8 girls to every 3 boys. You can make an equation to solve this: 8x + 3x = 528. 528 = 11x. Then divide 528 by 11 to get 48. x=48. 8(48) = 384 girls. 3(48) = 144 boys.
Answer:
(364.595 ; 391.405)
Step-by-step explanation:
Given the sample data:
406, 385, 389, 383, 352, 379, 388, 343, 368, 387
Using calculator :
Sample mean, xbar = 378
Standard deviation, s = 18.74
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
TCritical at df = 24 ; 0.05 = 2.262
Margin of Error = 2.262 * 18.74/√10 = 13.405
Lower boundary = (378 - 13.405) = 364.595
Upper boundary = (378 + 13.405) = 391.405
(364.595 ; 391.405)
The answer the i got was -2(5y-27). The simplified answer is -10y+54.
You distribute 32 and -32 through the parentheses, reduce the fraction with 2. Collect like terms: 12y+24-32y+32+10y-2 = -10y+24+32-2. Collect the sum- and you get -10y+54
Answer:
y=(constant not 0)
Step-by-step explanation:
"Which of the equations below"? What are those?
The general form for an equation parallel to the x-axis is y=... (... being a real number) because the y-value would remain constant, similar to how the x-axis is constantly at y=0. (Not 0, because parallel lines technically never intersect.)
Answer:
that's the answer
