Answer:
Negative line
Step-by-step explanation:
Going up is positive (think in going uphill)
Going down is negative
Answer: Well theres no table added but it probably looks like this
X Y
8mph 4 min
2mph 1 min
I think you can do the rest
The diagonal of a rhombus divides it into two congruent isosceles triangles.
So ∠CBD ≅ ∠CDB
∠CBD + ∠CDB + 68 = 180
2∠CBD = 180 - 68 = 112
∠CBD = 56
We also have
∠BDE + ∠E + ∠DBE = 180
∠DBE = 180 - 73 - 36 = 71
∠EBC = ∠EBD - ∠CBD = 71 - 56 = 15
Answer: ∠EBC = 15 degrees
Answer:
False
Step-by-step explanation:
We first write the equation in the form ax² + bx + c=0 which gives us:
3x² - 6x + 9=0
Given the quadratic formula,
x= [-b ±√(b²- 4ac)]/2a ,the discriminant proves whether the equation has real roots or not.
The discriminant, which is the value under the root sign, may either be positive, negative or zero.
Positive discriminant- the equation has two real roots
Negative discriminant- the equation has no real roots
Zero discriminant - The equation has two repeated roots.
In the provided equation, b²-4ac results into:
(-6)²- (4×3×9)
=36-108
= -72
The result is negative therefore the equation has no real solutions.
Answer: Our required probability is 39.69%.
Step-by-step explanation:
Since we have given that
Probability of a bowler getting a strike during a particular frame = 63%
Number of frames are performed = 2
We need to find the probability that the bowler would be most likely to get a strike in each of the two frames.
So, it becomes,

Hence, Our required probability is 39.69%.
