22
Step-by-step explanation:
It can be strung 22 ways!!
Answer:
Step-by-step explanation:
Let length = x and width =y
Area of rectangle = 20 square inches
x*y = 20
xy = 20 -------------(I)
Perimeter = 18 cm
2*length + 2*width = 18
2x + 2y = 18
Divide the entire equation by 2
x + y = 9
x = 9 -y -----------------(II)
Substitute x = 9 - y in equation (I)
(9 - y)*y = 20
9y - y² = 20
0 = 20 +y² - 9y
y² - 9y + 20 = 0
y² - 4y - 5y + 20 = 0
y(y - 4) - 5(y - 4) = 0
(y -4)(y -5) = 0
y - 4 = 0 ; y- 5 = 0
y = 4 ; y = 5
Length = 4 cm and width = 5 cm
Answer:
3/2
Step-by-step explanation:
Pick two points on the graph
(-1,2) and (3,8)
We can use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 8-2)/(3 - -1)
= (8-2)/(3+1)
= 6/4
= 3/2

Step-by-step explanation:
finally answer will be 0.000032
The probability of rolling 1 number, a four, on a 6-sided number cube, is 1/6.
On the second roll, the probability of rolling 1 number, a four, is again 1/6 (remember theoretical probability for one event does not consider previous rolls).
But the probability of rolling a four on 2 on consecutive rolls will be the probability of the first event times the probability of the second event. Think of it as rolling a four on the first time <em>and</em> the second time, and whenever there is "and" you need to multiply the probabilities. The probability of rolling a four on two consecutive rolls is
(1/6)*(1/6) = 1/36.
