Answer:
Probability (A sum of 10)=0.1025
Step-by-step explanation:
To find the Probability the sum is 10, we can either have
i. a 4 and a 6
ii. a 5 and a 5
Pr (A AND B) = Pr (A) x Pr(B)
Pr (A OR B) = Pr (A) + Pr(B)
Probability (A sum of 10) = Pr(getting a 4 AND a 6) OR Pr(getting a 5 AND a 5)
=(0.25 x 0.25)+(0.20 x 0.20)
=0.0625+0.04
=0.1025
Answer:
78+55=k
Step-by-step explanation:
110-32=78
55+78=k=133
Answer:
1 and 1/2 or 1.5
Step-by-step explanation:
3/8 × 4/1 = 3/2 = 1 and 1/2
Result in decimals: 1.5
Calculation steps:
3/8 × 4/1 = (3 × 4)/(8 × 1) = 12/8
12 ÷ 4 = 3
8 ÷ 4 = 2
= 3/2 = 1 and 1/2
Um i can help but are they all separate or
Answer:
m = 1/2 and b = 1.
Step-by-step explanation:
The y intercept (b) is at y = 1 so we have
y = mx + 1 so b = 1
The m is the slope of the line.
The graph passes through the point (4, 2)
From the graph, the slope = 2/4 = 1/2.
So it is y = 1/2x + 1.
