Answer:
the number of silver medals won by Brazil is 14
Step-by-step explanation:
The computation of the number of silver medals won by Brazil is shown below:
Given that
Total number of gold and silver medal wons by Brazil was 35
And, the ratio of number of gold medals to the number of silver medals be 3 : 2
Based on the above information
The number of silver medals won would be
= 35 × 2 ÷ (3 + 2)
= 35 × 2 ÷ 5
= 14
hence, the number of silver medals won by Brazil is 14
Answer: The y-value of the vertex is
Step-by-step explanation: we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
-----> this a vertical parabola open upward
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The vertex is the point
The y-value of the vertex is
The distance between those two points is 8 because its a straight line...
The probability of getting a 2 or a getting a black card, find individual probabilities;
A standard deck has 52 cards.
There are 4 2's in a normal deck; probability of getting it is 4/25
The probability of getting a black card is; 26/52 since half the deck is red and black.
Now add up the probabilities since it says "or"
(4/52)+(26/52)=30/52 probability of the card that you were dealt being a two or a black card.
Hope I helped :)
Answer:
This is not the answer this is the trick to find it
Step-by-step explanation:
The points after reflection will follow points equal but different direction, to the path followed before the reflection. So, if the line would cover 3.5 on the x and 5 on the y; it will reflect symmetrically giving you the formula to get your answer.
