Answer:
P(red) = .3
P(yellow) = .3
75 cubes in the box
Step-by-step explanation:
The probability has to add to 1
Since the number of red cubes equals the number of yellow cubes the probability has to be the same
.4 + x+x = 1
.4 +2x = 1
2x = 1-.4
2x = .6
Divide by 2
x = .6/2
x = .3
P(red) = .3
P(yellow) = .3
We know that
P(blue) = .4 = number of blue cubes/ total number of cubes
.4 = 30/total
total = 30/.4
total = 75
9514 1404 393
Answer:
-2018
Step-by-step explanation:
The n-th term is ...
an = a1 +d(n -1)
So, the given terms are ...
-53 = a1 +12d
-128 = a1 +37d
Subtracting the first from the second gives ...
(a1 +37d) -(a1 +12d) = (-128) -(-53)
25d = -75
d = -3
The 668th term will be ...
a668 = a1 +d(668 -1) = a1 +667d = (a1 +37d) +630d
a668 = -128 +630(-3) = -128 -1890 . . . . substitute for a38
a668 = -2018
Answer:
-2
Step-by-step explanation:
The output is y- value, the input is x-value
We can see on the graph y= 2 corresponds to x = -2
So the coordinates of same point are (-2, 2)
-2 is the answer
Answer:
<h2>2</h2>
Step-by-step explanation:
<h3>Let n= 4, m= -2 and j= 5</h3><h3 /><h3>(9n + 8m)/2j</h3><h3>= 9(4) + 8(-2)/2(5)</h3><h3>= 36 + (-16)/10</h3><h3>= 20/10</h3><h3>= 2</h3><h3 />
