A cube is numbered 1 through 6. If the cube is rolled twice, how many of the possible outcomes will have two even numbers? 3 9 18 36
======================================================
Explanation:
3/6 = 1/2 of the numbers on the cube are even (2,4,6)
If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.
There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.
---------
Those nine outcomes are listed below
A = 2, B = 2A = 2, B = 4A = 2, B = 6A = 4, B = 2A = 4, B = 4A = 4, B = 6A = 6, B = 2A = 6, B = 4A = 6, B = 6You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.
a basket contains red, green, yellow apples. An apple is selected at random if p(red) is 2/5 P(yellow) is 1/4 what is p(green)?
A. 3/20
B. 7/20
C. 1/10
D. 13/20
The probability of getting the green apple is 7/20 option (B) 7/20 is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
P(red) = 2/5
P(yellow) = 1/4
The sum of the probability of the event is 1.
P(red) + P(yellow) + P(green) = 1
2/5 + 1/4 + P(green) = 1
P(green) = 1 - (2/5 + 1/4)
P(green) = 7/20
Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.

Agroup of friends were working on a student film with a budget of $500, which they
spent on equipment and costumes, They spent $55 on costumes, What percent did
they spend on equipment?
Answer:
89%
Step-by-step explanation:
500-55=445
445/500=0.89
0.89x100=89
$500- $55= $445
445/500 = 89/100
89/100 × 100/1= 89%

A bag contains 5 red marbles, 6 blue marbles, and 9 green marbles. About how many red marbles would you expect to draw if you did 100 draws?
Answer: 25
Step-by-step explanation: Add all of the marbles, which is 20 in total, it is 5/20, so the ratio is 5:20
5:20 is 10:40, 15:60, 20:80, and 25:100
The answer is correct because 5:20 is 25% and 25/100 is also 25%

Denise bikes 3 miles to her friend's house, and then she bikes home. The average rate biking to her friend's house is twice the average rate coming home. Write and simplify an expression for the time it takes Denise to make a round-trip in terms of the average rate coming home x. Hint : Use d = rt.
Using the relation between velocity, distance and time, it is found that the expression for the total time is given by:
[tex]t = \frac{9}{2x}[/tex]
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex].
Denise bikes 3 miles to her friend's house, hence:
[tex]v_1 = \frac{3}{t_1}[/tex]
[tex]t_1 = \frac{3}{v_1}[/tex]
The average rate biking to her friend's house is twice the average rate coming home, hence, on the return, [tex]v_2 = 0.5v_1[/tex]:
[tex]v_2 = \frac{3}{t_2}[/tex]
[tex]t_2 = \frac{3}{v_2}[/tex]
[tex]t_2 = \frac{3}{0.5v_1}[/tex]
[tex]t_2 = \frac{6}{v_1}[/tex]
The total time is given by, considering [tex]v_1 = 2v_2 = 2v = 2x[/tex], as we want to consider x the rate coming home:
[tex]t = t_1 + t_2[/tex]
[tex]t = \frac{3}{2x} + \frac{6}{2x}[/tex]

A biased coin is flipped twice.
The probability of the coin landing on tailsis 0.4. Find the probability the coin lands on tails exactly once.
Answer:
0.48.
Step-by-step explanation:
There are 2 ways that a tail lands once:-
Tail + head or
head + tail.
Prob(Tail on one throw) = 0.4
Prob(Head on one throw) = 1 - 0.4 = 0.6.
Prob(Tail first then head) = 0.4 * 0.6 = 0.24
Head then tail has the same probability (0.6*0.4).
So the requred probability = 0.24 + 0.24
= 0.48.

[tex]\rm \dfrac{x^2 }{25} +\dfrac{y^2}{9} = 1[/tex]
What is an ellipse?Ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
The vertices (±5,0) and foci (±4,0) are given. Then the equation of the ellipse will be
We know that the general equation of the ellipse will be
[tex]\rm \dfrac{x^2 }{a^2} +\dfrac{y^2}{b^2} = 1[/tex]
Then the value of a will be
a = 5
And the value of the eccentricity will be
e = 4/5
Then the value of the b will be
[tex]\rm b^2 = a^2 - a^2e^2\\\\b^2 = 5^2 - 5^2 \times \dfrac{4^2}{5^2}\\\\b^2 = 25 - 16\\\\b \ = 3\\[/tex]

Solve for x,
x = 10
x = 15
x = 8
x = 12
[tex]~~~~~~(8x-17)+(3x+2)+63 = 180\\\\\implies 11x +48=180\\\\\implies 11x = 180-48\\\\\implies 11x = 132\\\\\implies x= \dfrac{132}{11}\\\\\implies x= 12[/tex]
Answer:
x = 12.
Step-by-step explanation:
The sum of the 3 angles is 180, so:
8x - 17 + 3x + 2 + 63 = 180
11x -15 + 63 = 180
11x = 180 + 15 - 63

Step-by-step explanation:
Mechanical energy is as much of potential and kinetic energy. Mechanical energy is never lost but only transformed from one form to another. As long as all the mechanical energy is as much as the potential energy then the kinetic energy is 0J. The mechanical energy of an object is found by summing its potential energy and kinetic energy.
