What fraction of the students are boys?
Answer:
7/11 are boys
Step-by-step explanation:
You add the total amount of students then put the number of boys in the numerator.
Brainliest please
Answer:
[tex]\frac{7}{11}[/tex]
Step-by-step explanation:
Ratio
7:4
Boys = 7
4 = Girls
________
When solving ratios, we need to get the denominator of the fraction, which can be found by finding the total of students in the school. There are 7 boys and 4 girls, so add :
7 + 4
11
So there are 11 kids in total and 11 is our denominator. Since we know that 7 boys are in the school, we can put 7 as our numerator, therefore :
[tex]\frac{7}{11}[/tex]

HELP ME ILL FRIEND U OR WHATEVER ANYTHING JUST HELP
Answer:
91.5 ft
Step-by-step explanation:
AS = BH AS= area of square
AS = (14) (6)
AS = 84
7ft + 4ft = 11ft
14ft - 11ft = 3ft
base of the triangles = 3ft
AT = BH/2 AT = area of triangle
AT = (3)(5)/2
AT = 7.5
TA = 84 + 7.5 TA = total area
TA = 91.5
Answer:
Area is 91.5ft squared
Step-by-step explanation:
6 * 14 = 84
The rectangle is 84ft.
7 + 4 = 11
14 - 11 = 3
5 * 3 = 15
15 / 2 = 7.5
84 + 7.5 = 91.5
Area is 91.5ft squared

The gondola conductor charges $2 for
each yodeler and $1 for each xylophone.
It costs $40 for the entire club, including
the xylophones, to ride the gondola.
Two yodelers can share a xylophone, so
the number of yodelers on the gondola is
twice the number of xylophones.
How many yodelers and how many
xylophones are on the gondola? Represent this problem with a system of equations. Let x represent the number of xylophones and let y be the number of yodelers.

la suma de las medidas de dos ángulos 80 grados y el complemento del primer ángulo es el doble de la medida del ángulo calcule la diferencia de las medidas de dichos ángulos
el complemento de un ángulo
Step-by-step explanation:
En este caso 70 ° y 20 ° son complementarios porque 70° + 20° = 90°.
Más ejemplos podrían ser 47° y 43°, ya que 47° + 43° = 90°, 30° y 60°, 45° y 45° , etc.
Dos ángulos son suplementarios si su suma forma un ángulo llano, es decir, 180°.
63% of US adults opposed to taxes on junk food and soda. You randomly select 10 US adults. Find the probability that the number of adults who oppose special tax on junk food and soda (a) exactly one, (b) at least four, and (c) less than eight
Answer:
a) 0.0008 = 0.08% probability that the number of adults who oppose special tax on junk food and soda is exactly one.
b) 0.9644 = 96.44% probability that the number of adults who oppose special tax on junk food and soda is at least four.
c) 0.7795 = 77.95% probability that the number of adults who oppose special tax on junk food and soda is less than eight.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they are opposed to taxes on junk food and soda, or they are not. Each adult is independent of other adults, which means that the binomial probability distribution is used to solve the question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
63% of US adults opposed to taxes on junk food and soda.
This means that [tex]p = 0.63[/tex]
You randomly select 10 US adults.
This means that [tex]n = 10[/tex]
(a) exactly one
This is [tex]P(X = 1)[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{10,1}.(0.63)^{1}.(0.37)^{9} = 0.0008[/tex]
0.0008 = 0.08% probability that the number of adults who oppose special tax on junk food and soda is exactly one.
(b) at least four
This is
[tex]P(X \geq 4) = 1 - P(X < 4)[/tex]
In which
[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{10,0}.(0.63)^{0}.(0.37)^{10} \approx 0[/tex]
[tex]P(X = 1) = C_{10,1}.(0.63)^{1}.(0.37)^{9} = 0.0008[/tex]
[tex]P(X = 2) = C_{10,2}.(0.63)^{2}.(0.37)^{8} = 0.0063[/tex]
[tex]P(X = 3) = C_{10,3}.(0.63)^{3}.(0.37)^{7} = 0.0285[/tex]
[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0 + 0.0008 + 0.0063 + 0.0285 = 0.0356[/tex]
[tex]P(X \geq 4) = 1 - P(X < 4) = 1 - 0.0356 = 0.9644[/tex]
0.9644 = 96.44% probability that the number of adults who oppose special tax on junk food and soda is at least four.
(c) less than eight
This is
[tex]P(X < 8) = 1 - P(X \geq 8)[/tex]
In which
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 8) = C_{10,8}.(0.63)^{8}.(0.37)^{2} = 0.1529[/tex]
[tex]P(X = 9) = C_{10,1}.(0.63)^{9}.(0.37)^{1} = 0.0578[/tex]
[tex]P(X = 10) = C_{10,2}.(0.63)^{10}.(0.37)^{0} = 0.0098[/tex]
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10) = 0.1529 + 0.0578 + 0.0098 = 0.2205[/tex]
[tex]P(X < 8) = 1 - P(X \geq 8) = 1 - 0.2205 = 0.7795[/tex]
0.7795 = 77.95% probability that the number of adults who oppose special tax on junk food and soda is less than eight.
