Answer:

1/6

Step-by-step explanation:

De la pregunta, sabemos:

30/90 del número de plantas de un cultivo de caña está contaminado.

30/90, simplificamos aún más

30/90 => 3/9 => 1/3

De estos, la mitad han sido tratados.

La fracción de los cultivos tratados son:

1/2 de 3/9 = 1/2 × 1/3

= 1/6

La fracción del número de plantas del cultivo que no ha sido tratada se calcula como:

1/3 - 1/6

El mínimo común denominador es 6

= (2 × 1) - (1 × 1) / 6

= 2 - 1/6

= 1/6

Usando proporciones, se encuentra que la fracción del número de plantas del cultivo que no ha sido tratada es [tex]\mathbf{\frac{5}{6}}[/tex]

Las plantas que no han sido tratadas son:

Por eso, la proporción total es dada por:

[tex]\frac{6}{9} + \frac{1}{2}\frac{3}{9} = \frac{6}{9} + \frac{3}{18} = \frac{12}{18} + \frac{3}{18} = \frac{15}{18} = \frac{5}{6}[/tex]

La fracción del número de plantas del cultivo que no ha sido tratada es [tex]\mathbf{\frac{5}{6}}[/tex]

3x^22−x^2+3

Step-by-step explanation:

Let's simplify step-by-step.

3x^22+2x+4−(x2+2x+1)

Distribute the Negative Sign:

=3x^22+2x+4+−1(x2+2x+1)

=3x^22+2x+4+−1x2+−1(2x)+(−1)(1)

=3x&22+2x+4+−x2+−2x+−1

Combine Like Terms:

Step-by-step explanation:

When reading the problem it tries to trip you up with the black dot. A line of symetery marks where you can cut the shape in half and have both parts equal. With the black dot a part of the shape there is only one way for a line of symetery to work as it can only be split in half that one way. No other corners have a black dot so there is no other way to split it where it would be symetrical.

Answer:

it means when x =0

so 6*0+12y=60

12y=60

y=5

Step-by-step explanation:

Answer:

In y intercept x = 0

so,we replace 0 in place of x

Step-by-step explanation:

6*0+12y=60

0+12y=60

y=60/12

y=5

Answer:

We have the system of equations:

y = -2*x

y = 2*x + 4.

To solve it by graphing, you need to graph both lines and see in which point the lines intersect each other.

You can see it in the image below. (blue is y = 2*x + 4, and green is y = -2*x)

We also can calculate the solution with math, let's do that:

y = -2*x

y = 2*x + 4.

We can replace the first equation in the second one, to get:

-2*x = 2*x + 4

Now let's solve this for x

-2*x -2*x = 4

-4*x = 4

x = 4/-4 = -1

Evaluating this in one of the equations we get:

y = -2*-1 = 2

Then the solution is the point (-1, 2), exactly what we can see in the graph.

Answer:

D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.

Step-by-step explanation:

In statistics, type I error is when we reject the null hypothesis even when it is true.

Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.

This means that a type I error will be;

Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.

Answer:

Total wage= $680

Step-by-step explanation:

Giving the following information:

Regular wage= $10

One and a half= $15

Double= $20

To calculate the total wage, we need to use the following formula:

Total wage= x*10 + y*15 + z*20

x= normal hours

y=one and a half hours

z= double hours

Total wage= 40*10 + 8*15 + 8*20

Total wage= $680

Answer:

Fraction of composite numbers = 6/10

Fraction of prime numbers = 4/10

Step-by-step explanation:

A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.

Thus, it means that the set of numbers given to us which is;

(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;

12, 14, 15, 16, 18, 20

This is because each of them have at least one divisor that is neither itself or 1.

Thus, we have 6 out of the 10 numbers as composite.

Fraction of composite numbers = 6/10

Now, a prime number is a number that are only divisible by itself and 1.

Thus,from the given set, the prime numbers are; 11, 13, 17 & 19

We have 4 out of 10 numbers as prime numbers.

Thus, fraction of prime numbers = 4/10

Answer:

7.2 *10⁻⁵

Step-by-step explanation:

Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.

The standard form of scientific notation is expressed as;

A * 10ⁿ

A is a value from 1 to 9

n is any integer.

Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;

0.000072 = 7.2 *10⁻⁵ where;

A = 7.2 and n = -5

Note that the power is a negative value since the value is less than 1.

Answer:

$16

Step-by-step explanation:

To find the cost per square foot we have to solve the given equation for x:

6.4x - 3.7x = 43.2

2.7x = 43.2

Divide both sides of the equation by 2.7 to isolate the x:

2.7x/2.7 = 43.2/2.7

x = 16

The sheet metal costs $16 per square foot.

Answer:

Step-by-step explanation:

Given the area of the square as A = 98ft²

The side length of the square will be equivalent to the diameter of the circle.

First we need to get the length of the square.

Area of a square = L^2

98 = L²

L = √98

L = 9.89 ft

Hence the diameter of the circle is 9.89 ft

radius = diameter/2

radius = 9.89/2

radius ≈ 4.95 feet

Hence the radius of the circle is approximately 4.95 feet
