Can someone please help me with this?

Answer:

2/3

Step-by-step explanation:

divide the numerator and denominator by the same number until they are prime numbers

remember: if you divide the numerator by 2 you MUST divide the denominator by 4 as well. The rule is that you divide the numerator and denominator by the same number at the same time

in this case divide both by 2 to get 2/3

0.45 will be  the probability that the student is on a sports team or takes at least one AP class

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, At a local high school, 30% of the students are on a school sports team, 25% take at least one Advanced Placement (AP) class,

So,

Probability of Getting a student from a sports TeamP(A) = 0.3

Probability of Getting a student from an AP class P(B)= 0.25

Since 10% are on a sports team and take at least one AP class.

P(A ∩ B ) = 0.10

Thus,

P(A∪B) = P(A)  + P(B) - P(A ∩ B )

P(A∪B) = 0.30  + 0.25 - 0.10

P(A∪B) = 0.45

therefore,  the probability that the student is on a sports team or takes at least one AP class will be 0.45.

Answer:

Habrán 10175 enfermos a los 15 dias.

Step-by-step explanation:

La tasa de cambio de la población enferma por la epidemia de gripe es:

[tex]N'(t)=120t-3t^2[/tex]

Donde t es el tiempo en dias, y se sabe que la epidemia inició en N(0)=50.

a)

Para encontrar la función original que describe el comportamiento de la epidemia, debemos integrar la función:

[tex]N(t)=\int N'(t)dt[/tex]

[tex]N(t)=\int (120t-3t^2)dt[/tex]

Integrando:

[tex]\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C[/tex]

Simplificando:

[tex]\displaystyle N(t)=60t^2-t^3+C[/tex]

Para determinar el valor de C, usamos la condición inicial N(0)=50:

[tex]\displaystyle 50=60(0)^2-(0)^3+C[/tex]

Se tiene que C=50, y la función queda determinada como:

[tex]\displaystyle N(t)=60t^2-t^3+50[/tex]

b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:

[tex]\displaystyle N(15)=60(15)^2-(15)^3+50[/tex]

Calculando:

[tex]N(15)=13500-3375+50=10175[/tex]

Habrán 10175 enfermos a los 15 dias.

Step-by-step explanation:

Step-by-step explanation:

Step 1:  List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2:  Find the value of RS

cos(31) = RS/24.8 NOT 24.8/RS

sin(31) = QS/24.8 NOT RS/24.8

sin(31) = QS/24.8 NOT 24.8/RS

cos(31) = RS/24.8 WHICH IS SAME AS RS/24.8

Answer: The correct length would be given from Option D, cos(31) = RS/24.8

She will need to buy 3 packs to make 6 different balloon animals.

Step-by-step explanation:

Given that the balloon artist wants to make 6 different animals, and each animal involves using 4 balloons, to make those 6 animals she must use 24 balloons, as the following calculation shows:

6 x 4 = 24

Now, since the balloons come in packs of 8 units, to make those 6 animals she must buy 3 packs of balloons, as this calculation also shows:

24 / 8 = 3.

Answer:

20.4

Step-by-step explanation:

Constant of proportionality, k, is given as [tex] \frac{y}{x} [/tex].

Given that number of miles driven by Lily is directly proportional to the number of gallons she used, therefore the constant of proportionality between the number of miles driven and the number of gallons used can be determined by using any given pair from the table of values.

Using, (50, 1020),

constant of proportionality (k) = [tex] \frac{1020}{50} = 20.4 [/tex].

The constant of proportionality is 20.4 miles per gallon.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the distance driven in miles for x galloons.

From the table, using the points (37, 754.8) and (50, 1020):

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-754.8=\frac{1020-754.8}{50-37}(x-37)\\\\y-754.8=20.4(x-37)\\\\y=20.4x[/tex]

Therefore the constant of proportionality is 20.4 miles per gallon.
