Step-by-step explanation:
A bag contains 8 white marbles, 6 red marbles and 4 blue marbles. How many blue marbles must be added to the bag so that the probability of choosing a blue marble is 1/2?
Answer:
5 marbles
Step-by-step explanation:
A bag contains
8 white marbles
6 red marbles
4 blue marbles.
Total number of marbles is :
8 + 6 + 4
= 18 marbles
Based on this current proportion
The Probability of choosing a blue marble = Number of blue marbles/ Total number of marbles
In order for the Probability of choosing a blue marble to be 1/2
The number of blue marbles has to be:
= 18 marbles × 1/2
= 9 blue marbles
From the question we have 4 blue marbles, hence:
9 blue marbles - 4 blue marbles
= 5 blue marbles
Therefore, 5 blue marbles must be added to the bag so that the probability of choosing a blue marble is 1/2.
Answer:
The actual answer would be 10 marbles.
Step-by-step explanation:
1. we had started off by adding 8+4+6 to get the total number of marbles. If we do that, we will get that there are 18 marbles in total.
2. here is where the others went wrong. If we say that we need 5 blue marbles to get 9/18 blue marbles, you are wrong. This is because we have to add 5 to the total number of marbles as well. Then we get 9/23 marbles. which is clearly not 1/2,
3. However, if we multiply 5 by 2, we get 10 blue marbles. if we add 10 to the original 18, we get 28 total marbles. Now if we add 10 to 4 we get 14 blue marbles.
SUCCESS!!!
14/28 blue marbles is 1/2, therefore we must add 10 blue marbles.

What is the image point of (5,1) after a translation right 5 units and down 2 units?
Answer:
(10,-1)
Step-by-step explanation:
If it shifts right, that means that the x is increasing
5+5 = 10
if it shifts down, that means the y is decreasing
1-2=-1
x= 10 y=-1
(10,-1)
Graph y = 3/4x + 2

One container of ice cream holds 9 scoops of ice cream. One package of ice cream cones has 12 cones. We want to make the fewest number of cones, with one scoop of ice cream on each cone and no ice cream or cones left over. How many containers of ice cream and packages of cones should be purchased? How many ice cream cones will we be able to make? The fewest number of ice cream cones we will be able to make is . We need to purchase containers of ice cream and packages of ice cream cones.
Answer:
1. There will be 4 ice cream containers and the number of ice cream cone package is 3.
2. will be able to make 36 ice cream cones and this is the fewest number of ice cream cones.
Step-by-step explanation:
One container of ice cream holds 9 scoops of ice cream.And, one package of ice cream cones has 12 cones.we have to find the least common multiple of 9 and 12 which is 36 and there must be 36 ice cream scoops and 36 ice cream cones.So, there will be 36/9 =3 ice cream containers.and the number of ice cream cone package is 36/12=3That gives you your answerHOPE THIS HELPS, GOOD LUCKPlease solve!! :)

Write sin (4theta) in terms of sin (2theta) and cos (2theta).
Answer:
2 sin 2 theta cos 2 theta
Step-by-step explanation:
Mathematically;
sin (4theta) = sin (2theta + 2theta)
Using the sine addition rule
That would be;
sin 2 theta cos 2 theta + sin 2 theta cos 2 theta
= 2 sin 2 theta cos 2 theta

Answer:
12.12
Step-by-step explanation:
SO its A special right triangle which means its. 30,60,90 triangle
we know the bigger leg is 14
so we divide that by 2 since
leg 1 = Unknown (y)
leg 2= 2y=14
Since leg 1 is basically half of leg 2, we divide leg 2 by 2 and get 7
now for the hypotenuse Its just y√3 so in this case y is 7
SO when solved 7√3 you’d get 12.12 rounded

Darla's family went on a vacation to Yellowstone Park. On day 1, they drove 14 the total distance, and on day 2 they drove an additional 15 the total distance. Which shows about how far the family has left to travel to Yellowstone Park?
Answer:
11/ 20
Step-by-step explanation:
Given that:
Fraction traveled on first day = 1/4
Fraction traveled on second day = 1/5
In fraction form, the total distance to be traveled is represented as 1
Total distance covered during the two days ;
(1/4 + 1/5)
L.C.M of 5 and 4 = 20
(5 + 4) / 20
= 9/20
Distance left to cover :
Total distance - total distance already covered
1 - 9/20
(20 - 9) / 20
11 / 20

CAN SOMEONE PLEASE HELP ME???
Answer:
C
Step-by-step explanation:
The blue line is the one that that slants from lower right to upper left. It has a negative slope as in - 1/2. The line is solid so that means the values of the line are included in the expression.
The area covered is purple, so y is less than the y values of the line. C is the only value that shows the paragraph above.
But we have to check the other inequality just to make sure you are right. y > 2/3 x - 4. The line is not included, so C is your answer.
