Answer:
-15
Step-by-step explanation:
0)(2)+(2)(0)−15
=−15
(-2,0) instead of substitution, you can use elimination which the 3x's will cancel out and you solve the system regularly
Answer:
9π units²
Step-by-step explanation:
To obtain an exact answer, use π, not an approximation such as 3.14.
A = πr² is the appropriate formula.
Here,
A = (3)^2·π units², or 9π units²
Answer:
9.19 mi. is the distance between Bank and Grocery store.
Step-by-step explanation:
As we know in a given triangle with sides a, b, c which are the opposite sides of ∠A, ∠B, ∠C, follow the property
Now we apply this property in the given triangle.
Let the distance between Grocery store and Bank = x mi
So the answer is 9.19 mi.
Answer:
0.397
Step-by-step explanation:
In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:
HTTT,THTT,TTHT and TTTH
The probability of flipping a head, P(Head)=0.18
Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82
We can then calculate the probability that there is a single heads out of the 4 flips
=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)
=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X 0.82 X 0.82) + (0.82 X 0.82 X 0.18 X 0.82 )+ (0.82 X 0.82 X 0.82 X 0.18)
