Answer:
16/33
Step-by-step explanation:
Tổng của cả 4 tấm thẻ là một số lẻ khi:
Có 1 thẻ là lẻ, 3 thẻ còn lại là chẵn, có: 6C1.5C3=60 cách
Có 3 thẻ là lẻ, 1 thẻ là chẵn, có: 5C1.6C3=100 cách
Suy ra có 160/11C4=16/33 cách
Answer:
x = -1
Step-by-step explanation:
5x + 3y = 26
- (6x + 7y = 21)
_________
-x - 4x = 5
-5x = 5
x = -1
Answer:
width 9'' length 9''
Step-by-step explanation:
2 " is cut off from both sides
so the base of the box will be a square
area * height = volume of box
side = x
height =2
2x^2=162
x^2=81
x=9 inches the side of the box
Volume =162
V=area*height V= 81*2= 162
Answer:
R2 = 6.44
T2 = 8.82
Whole = 30.42
Step-by-step explanation:
R1 = 2.8 X 3.1
T1 = (1/2) X (2.4) X (5.4)
R2 = (5.4-3.1) X (2.8) = 6.44
T2 = (1/2) X (11.7-5.4) X (2.8) = 8.82
Whole = (1/2) X (11.7) X (2.4+2.8) = 30.42
Answer: If you are looking for Slope-Intercept form (y=mx+b), It would be...
y=-5.4x+10840.4.
If you are looking for Point-Slope form, it would be...
y=-5.4x+10840.4.
Step-by-step explanation: Write in Slope-Intercept from, y=mx+b.
Point-Slope form : Use the Point-Slope formula, y-y1=m(x-x1) to find the equation of the line.
I hope this helps you out! ☺
