Solve:
At the high school, 1/3 of the students play an instrument. Of the students who play an instrument, 2/3 play a string instrument. What fraction of the students at the high school play a string instrument?

Answer:

x = 13/15

Step-by-step explanation:

If x - 1/5 = 2/3,

you can find x by doing 2/3 + 1/5.

2/3 = 10/15

1/5 = 3/15

10/15 + 3/15 = 13/15!

Answer:

The ordered pair (15, 12) means that 15 pounds of beans cost $12.

Step-by-step explanation:

Ordered pairs are in the format of (x,y). The first number represents a point's position on the x-axis and the second represents a point's position on the y-axis. Also note that in this graph, the x-axis represents the weight of beans in pounds and the y-axis represents the cost of beans.

Knowing this, (15,12) means that 15 pounds of beans must cost $12.

Note:

You did not mention the table of the points. But, I would try to clear your concept by taking 6 sample points.

Answer:

The table and the graph of the function h(x) = 4x-2 is also attached below.

Step-by-step explanation:

Given the function

[tex]h(x) = 4x-2[/tex]

substituting x = 0 in the function

h(0) = 4(0) -2 = 0 -2 = -2

Therefore, the point (0, -2) satisfies on the function.

substituting y = 1 in the function

h(1) = 4(1) -2 = 4 -2 = 2

Therefore, the point (1, 2) satisfies on the function.

substituting y = 2 in the function

h(2) = 4(2) -2 = 8 -2 = 6

Therefore, the point (2, 6) satisfies on the function.

substituting y = 3 in the function

h(3) = 4(3) -2 = 12 -2 = 10

Therefore, the point (3, 10) satisfies on the function.

substituting y = 4 in the function

h(4) = 4(4) -2 = 16 -2 = 14

Therefore, the point (4, 14) satisfies on the function.

substituting y = 5 in the function

h(5) = 4(5) -2 = 20 -2 = 18

Therefore, the point (5, 18) satisfies on the function.

Therefore, we conclude that table:

x                  h(x) = 4x-2

0                  -2

1                    2

2                   6

3                   10

4                   14

5                   18

The graph of the function h(x) = 4x-2 is also attached below.

Answer:

0,4

Step-by-step explanation:

1. 2/5=0,4; 6/15=0,4; 8/20=0,4. It means, the constant of proportionality is 0,4.

2. if the constant value is 0,4, then x:1=0.4 ⇒ x=0,4

Step-by-step explanation:

Step-by-step explanation:

Sum of angles in a triangle = 180°

Angle W = 180° - 62° - 57° = 61°

The shortest side is directly opposite the smallest angle.

(for acute angles)

Hence the shortest side is opposite 57°, which is VW.

Answer:

VUW

62 + 57 + x = 180

119 + x = 180

x = 180 -119

x= 61

therefore smallest angle is 57° (vuw)

Answer:

Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.

Step-by-step explanation:

x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.

< means lesser.

> means more than.

A filled up dot means that the number itself is included in the values of x.

A non-filled up dot means that the number itself is not included in the values of x.

An arrow facing left means lesser than that number.

An arrow facing right means more than that number.

Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

Answer:

The range for points scored is greater than the range for points allowed.

Step-by-step explanation:

Points scored: 175

Points allowed: 168

The true sentence is that the range for points scored is greater than the range for points allowed.

The mean of observations is equal to the ratio of sum of all the observations and the number of observations.

Points scored by the lion in the 8 games are

24 + 21 + 18 + 17 + 24 + 31 + 22 + 28 = 175.

Points allowed in the 8 games are

16 + 10 + 27 + 21 + 21 + 24 + 28 = 168

Thus, the range for points scored is greater than the range for points allowed.​

Answer:

the length of the second rectangle is 33.75 in

Step-by-step explanation:

The computation of the length of the second rectangle is as follows

Let us assume the length of the second triangle be x

Now

The equation would be

4 ÷ 15 = 9 ÷ x

Now do the cross multiplication

4x = 15 × 9

4x = 135

x = 33.75 in

Hence, the length of the second rectangle is 33.75 in

Answer:

firstly we have to do cross multiplication

Answer:

B. The count of drawing a red ball is a binomial distribution.

Step-by-step explanation:

The count of drawing a red ball can be gotten by binomial distribution because:

the chance of success; p = 26/50 and chance of no failure; q = 24/50

For example, If we want to find probability of getting 5 red balls out of 20 selections, we will use the binomial probability distribution formula;

P(X = 5) = C(20, 5) × p^(5) × q^(20 - 5)

This same procedure also applies if we want to get the probability of getting a number of yellow balls out of a number of selections from the bag.

Looking at the options, the best option that explains how it's binomial probability that works is option B
