Answer:
6in
Step-by-step explanation:
Using the pythagerous thereom,
10^2 = 8^2 + b^2
b^2 = 10^2-8^2
b^2 = 100-64
b^2 = 36
b = 6

Step-by-step explanation:
it's gonna either be B or D
<em>Answer:</em>
<em>a is greater than 1, so a−1 is positive.</em>
<em />
<em>The distance between a and 1 appears to be less than the distance between 1 and 0, so it looks like a is less than 2. Thus a−2 is negative.</em>
<em />
<em>b is negative, so −b is positive.</em>
<em />
<em>The distance between a and 0 appears to be less than the distance between b and 0, so it looks like |a| is less than |b|. Since b is negative and a is positive, a+b is negative.</em>
<em />
<em>a−b = a+−b. Since b is negative, −b is positive. a is also positive. Thus, a−b is positive.</em>
<em />
<em>Since |a| and |b| are both greater than 1, |ab| is also greater than 1 (this builds on the intuition students gained in fifth grade as in 5.NF.5). ab is negative since a is positive and b is negative. Thus, ab+1 is negative.</em>
To find the value of r
We will follow the steps below
Usinf the equation of a slope:
slope(m) =
from the question given;
m= -3/4
x₁ = 3
y₁=4
x₂=-1
y₂=r
substituting the values into the slope formula
we can now simplify and then solve for r
cross-multiply
-3 x -4 = 4(r-4)
12 = 4(r-4)
Divide both-side of the equation by 4
3 = r - 4
add 4 to both-side of the equation
3+4 = r-4+4
7 = r
r=7
Therefore the value of r is 7
The probability that it is pink or canvas is 0.9
Step-by-step explanation:
Let us revise the meaning of "or" , "and" on probability
:
- The use of the word "or" means that you are calculating the probability that either event A or event B happened. Both events do not have to happen
- The use the word "and", means that both event A and B have to happen
The addition rules are:
- P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
- P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)
Anna is shopping for a new backpack
∵ The probability that the backpack is pink is 0.7
∴ P(pink) = 0.7
∵ The probability that it is canvas is 0.7
∴ P(canvas) = 0.7
∵ The probability that it is pink and canvas is 0.5
∴ P(pink and canvas) = 0.5
Substitute the values above in the rule below
∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)
∴ P(pink or canvas) = 0.7 + 0.7 - 0.5
∴ P(pink or canvas) = 0.9
The probability that it is pink or canvas is 0.9
