A student from the community college is selected at random. Find the probability that the student is at last 31. Round approximations to three decimals places
Answers
Answer:
0.077
Step-by-step explanation:
From the table :
Number of students aged 31 - 35 = 60
Number of students over 35 = 26
Total number of students = total possible outcomes = 1123
Required outcome = (students aged 31 - 35) + over 35 = 60 + 26 = 86
Probability = required outcome / Total possible outcomes
Probability (at least 31) = 86 / 1123 = 0.0765
= 0.077 (3 decimal places)

Raj and Tom are the top scorers on their team. One season, raj scored one quarter of their team’s goals. Tom scored one sixth of their teams goals. Raj and Tom scored a total of 25 goals. How many goals did their team score?
Answers
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.
Calculations and ParametersLet 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.

Hello please help me! There are 3 questions, I will give brainliest!
Answers
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.

Step-by-step explanation:
Based on the tangent theorem, tangents drawn from an external point of a circle are equal.
This means:

4x - 2x = 1 + 9
2x = 10
Divide both sides by 2

You have to use the Pythagorean theorem to find the missing side length
So it would be 10 squared plus 12 squared equals 15.62
Then you double it because of the two top side lengths
Then you use the Pythagorean theorem for the bottom
12 squared plus 30 squared which equals 32.31
And you double that as well
31.24 plus 64.62 equals 95.86 and you just round to 95.8

Alejandro compra un terreno de 0,3 hm cuadrados y 0,9 dam al cuadrados ¿cuanto ha pagado por el terreno
Answers
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
