Answer:
Ok so I’m stuck with this question too But I got the top part.
p=1/6
q=2/6
r=3/6
s=3/6
A) The probabilities placed at P, Q, R and S on the tree diagram are;
P = 1/6; Q = 1/3; R = 1/4; S = 1/4
B) The probabilities of her winning or losing is;
Probability that she will win = 5/12
Probability that she will lose = 7/12
A) From the given tree diagram, we can see that;At point P; Only 1 is rolled.
Since there are 6 possible numbers, then Probability at P = 1/6
At point Q; either 2 or 3 can be rolled.
Since there are 6 possible numbers, then Probability at Q = 2/6 = 1/3
At point R; 4,5, or 6 can be rolled on first roll.
Thus, Probability on first roll = 3/6
At R on second roll if she gets even, probability on second roll = 3/6
At S on second roll if she gets odd, probability on second roll = 3/6
Thus;
Overall probability at R = 3/6 × 3/6 = 1/4
Overall probability at S = 3/6 × 3/6 = 1/4
B) Probability that she will win are the probabilities at P and R.Thus, probability that she will win = 1/6 + 1/4 = 5/12
Probability that she will lose are the probabilities at Q and S.
Probability that she will lose = 1/3 + 1/4 = 7/12

When Jose woke up the temperature was 74°. It
reached a high temperature of 91°. What was
the percent of increase of these temperatures?
Answers
Answer:
22.97
Step-by-step explanation:
Given that,
Initial temperature = 74°
After some time, the new temperature = 91°
We need to find the percent increase in the temperature.
The formula for the percentage increase is given by :
[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{91-74}{74}\times100\\\\=22.97\%[/tex]
So, the increase in temperature is 22.97%.

Answers
Answer:
1.) 5 2.) 10.58
Step-by-step explanation:
For each one, you use the equation a^2 + b^2 = c^2 where c is the "hypotenuse"-- the side of the triangle opposite (facing) the right angle which is shown with a small box. The variables a and b do not matter, as long as they are the "legs", the other 2 sides.
So it is 4^2 + 3^2 = c^2 which simplifies to 16+9=25=c^2 and square root both sides and you get c=5
and 12^2 + b^2 = 16^2 which simplifies to 144+ b^2 = 256 and subtract 144 from both sides and you get b^2 = 112 and square root both sides and it is approximately 10.6 :)

A figure has been dilated from the origin by a scale factor of one seventh. if another dilation from the origin maps the dilated image back
onto the original figure, what is its scale factor?
Answers
Answer:
its scale factor is 3
Step-by-step explanation:
plz mark brainliest
To map the dilated image back onto the original figure, the scale factor needed is 7.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor.
If a figure is dilated from the origin by a scale factor of one seventh, it is given by:
(x, y) ⇒ [(1/7)x, (1/7)y]
To map the dilated image back onto the original figure, the scale factor needed is 7. Hence:
[(1/7)x, (1/7)y] ⇒ (x, y)
