Answer:

1) There are 13 students in Jerry's study.

2) There are 39 students in Kathy's study.

3) Jerry's study is more trustworthy!

Step-by-step explanation:

1) Jerry's study is the one with the dot plot.

Now, the number of students is calculated by adding the total number of dots in the plot.

We have a total of 13 dots.

Thus, there are 13 students in Jerry's study.

2) Kathy's study is the one with the histogram.

The total number of students is gotten by adding the corresponding number of students on the y-axis for each range of distance on the x-axis.

Total number of students = 9 + 11 + 7 + 12 = 39 students

3) Jerry's study where he used a dot plot is likely to be more trustworthy because it gives exact values of the number of students for each distance represented whereas, Kathy's study where she used a histogram doesn't give exact values but just gives a range of distances for a particular number of people.

Answer:

Si el metro cuadrado es a $ 50 Alejadro pagó por el terreno  $195 000

Step-by-step explanation:

Ya que no se especifica un valor por unidad de área podemos suponer por  ejemplo $ 50 / metro^2

Terreno:

0.3 hm^2

0.9 dam^2

1) Vamos convertir a la misma unidad de área las áreas del terreno para poder saber su costo.

-Hectómetro cuadrado

1 hm^2  = 10 000 m^2

Por lo tanto,

0.3 hm^2 * 10 000 m^2 /  1 hm^2 = 3000 m^2

-Decámetro cuadrado

1 dam^2  = 1 000 m^2

Por lo tanto,

0.9 dam^2 *  1 000 m^2 /1 dam^2  = 900  m^2

Así que el total del terreno es de 3900 m^2

2) Ahora podemos calcular el valor total del terreno

area* valor (por m^2)

3900  m^2  * $50/ m^2 =  $195 000

Step-by-step explanation:

the height of the rhombus is 12 inches

explanation: to find area you need to multiply langth times hight. 18×12=216

Answer:

h = 12 in.

Step-by-step explanation:

218 in.² ÷ 18 in.

12 in.

Answer:

30

Step-by-step explanation:

To calculate the area of a triangle you will do it like a square or rectangle but you will divide your answer by 2. So...

10 * 6 = 60

60 / 2 = 30

=============================================================

Explanation:

A secant line cuts the circle so that part of the line is inside the circle, and the rest (or majority) of the line is outside the circle. In other words, the secant line intersects the circle at exactly two points.

This is in contrast to a tangent line that only touches the circle at exactly one point. Line L is the tangent line in this case.

Segment DC is a diameter of the circle as it goes through the center, and this segments endpoints are on the circle's edge. The segments AD and AC are radii of the circle.

Answer:

11.3 (√128)

Step-by-step explanation:

[tex] \\ {a}^{2} + {b}^{2} = {c}^{2} [/tex]

in this case a is given and c is given

a =side of the triangle

b= side of the triangle

c = hypotenuse or the longest side of the triangle

4^2 + b^2 = 12^2

16+ b^2 = 144

144 - 16 = b^2

128 = b^2

√128 = b

11.3137...= b = 11.3 (rounded to nearest tenth)

Answer: 3. 28-21x

Step-by-step explanation: distribute the 7 to both 4 and -3x

7 x 4= 28

7 x -3x = -21x

28-21x

Hope this helps (^_^)

Answer:

28 - 21x

Step-by-step explanation:

7(4 - 3x)

7×4 = 28

7× -3x = -21x

Step-by-step explanation:

[tex] \frac{1}{4} x + \frac{1}{6} x = 25 \\ \frac{5}{12} x = 25 \\ x = 60[/tex]

let x be the team's goals.

formulate an equation in order to find the value of x, then solve

The number of goals which their team scored was 60 goals.

Let their team goal be denoted with x[tex]\frac{5}{12} x = 25\\[/tex]

Raj scored one-quarter of their goals

Tom scored one-sixth of their goals

They both scored a total of 25 goal

Mathematically, this is denoted by:

[tex]\frac{1}{4}x + \frac{1}{6}x = 25[/tex]

[tex]\frac{5}{12}x = 25[/tex]

x= 60.

Therefore, the team scored a total of 60 goals.
