Answer:
Step-by-step explanation:
The slope-intercept form is
y
=
m
x
+
b
, where
m
is the slope and
b
is the y-intercept.
y
=
m
x
+
b
Ok so for 1000m= 1km that means since 500 is half of 1000, 1/2 is half of 1
Answer:
x y
0.75 6
1.5 12
3 24
Step-by-step explanation:
Proportional relationship between x and y is often written as y = kx.
In the table,
x = 0.75 and y = 6
x = 1.5 and y is unknown.
Since then
When multiplying 12 by 2, you get 24 and when multiplying 1.5 by 2, you get 3, so the last row is x = 3 and y = 24.
Now THAT's a problem !
Lemme at it ! Outa my way !
The probability of picking two of the friends to work together is
(the number of pairs of friends there are)
divided by
(the total number of pairs that can be pulled out of 21 students).
The number of pairs of friends there are is (3 x 2) / 2 = 3 pairs.
The total number of pairs that can be selected out of 21 students is
(21 x 20) / 2 = 210 pairs.
The probability that the pair selected will be two of the friends is
3 / 210 = 1/70 = about 1.43 % (rounded)
It would be 70% of 400
490(.7) = 280
