Answer:

You would have to add 4 blue marbles

Step-by-step explanation:

there are a total of 12 marbles, 4 of them being blue.

If you add 4 blue ones, there would be a total of 16 marbles and 8 of them would be blue.

8/16 = 1/2

Therefore, 4 blue marbles need to be added for the chance to draw one to be 1/2 or 50%

Answer:

Step-by-step explanation:

Since there is 1 green, 2 yellow, 4 blue, and 5 red we start with 12 marbles. For the probability of picking a blue to be 1/2 we must satisfy.

(b+x)/(12+x)=1/2. (Where x is the number of blue marbles added)

2(b+x)=12+x

2b+2x=12+x

2b+x=12

x=12-2b, since we started with 4 blue marbles

x=12-2(4)

x=12-8

x=4

So we would need to add 4 blue marbles to make the probability of picking a blue 1/2.

Answer:

200 packets

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Fish flavoured = 25kg or 25,000 gm

Chicken flavoured = 35 kg or 35,000 gm

Packets size = 300gm

So, we can calculate the number of packets by using following formula,

Number of packets = (25,000gm + 35,000gm) ÷ 300gm

Number of packets = 60,000 gm ÷ 300gm

Number of packets = 200 packets

Answer:

22 (4th option)

Step-by-step explanation:

The side lengths are useless.

Pay attention to the angles.

<QRP=68 degrees.

Vertical angles make it so <SRT=68

180-90(right angle)-68=22 degrees

Your answer is the image below.

To graph this inequality, Rearrange the Y so everything right is now left, and then plot Y on a number line. Lastly, shade or leave the circle open or closed.

Greater than or less to = OPEN circle (Not shaded)

Greater and/or less than or equal to = CLOSED circle (Shaded)

Answer

X= 6

Y= 19

Step-by-step explanation:

add the 1/5 over and simplify

Answer:

y = -4/5x - 11/5

Step-by-step explanation:

4x = -5y (-) 11

4x = -5y - 11

-5y = 4x + 11

5y = -4x - 11

y = -4/5x - 11/5

Answer:

The average rate of change is 8

Step-by-step explanation:

Mathematically, we have the average rate of change over a given interval as;

f(b) - f(a)/b-a

Where the interval is [a,b]

With respect to this question, a = 3 and b = 5

f(a) = f(3) = 3^2 - 4 = 9-4 = 5

f(b) = f(5) = 5^2 - 4 = 25-4 = 21

Thus, the average rate of change over the intervals will be;

(21-5)/(5-3) = 16/2 = 8

Step-by-step explanation:

The Range is not used to measure of the center of a data set.

Here,

We have to find, which is not a measure of the center of a data set.

What is Range?

The range of a set of data is the difference between the largest and smallest values.

Now,

Median is the middle number, when data is arranged in numerical order.

Mean is the average of a data set.

Mode is the data item the appears most frequently.

Hence,

Median, Mean, Mode all are used to measure of the center of a data set.

So, Only The Range is not used to measure of the center of a data set.

Option 3 is true.
