Leo wants to determine the average number of texts middle school students send in a day. Since all middle school
students are enrolled in history, he randamly surveyed 4 'students from each of Mr. Barnes's eighth-grade history
classes. Ms. Lopez and Mrs. Frank also teach eighth-grade history. What should Leo do to ensure his sample is
representative of all middle school students?
O He should take the sample as is because he randomly surveyed students in each of Mr. Barnes's classes.
He should also take a sample from Ms. Lopez's and Mrs. Frank's classes so that each student has the same
chance of being chosen.
O He should also take a sample from each of the other history classes in all of the other grades in the middle school.
O He should survey al the students in all the history classes to make sure he collects enough data.

Given the function below, what is the value of g(4)?

g(x)=3x2−3x−9

Select one:
A. 15
B. 27
C. 38
D. 56

Answers

Answer:

g(x) = 3x^2-3x-9

g(4) =3(4)^2-3(4)-9

g(4)=3(16)-12-9

g(4)=48-12-9

g(4)=27

So B is the correct answer.

What is the distance from point (-5, 6) to point (-5.-2)?​

Answers

Answer:

8

Step-by-step explanation:

(-5,6) (-5,-2)

Notice how the two points have the same x-coordinate. This means that they are directly on top of each other. To find their distance, all we need to do is subtract their y-coordinate values.

6-(-2)

Two negatives make a positive

6+2

8

Therefore, the distance between the two points is 8 units.

I hope this helps!

The perimeter of a right-angled triangle is 96 cm.
The lengths of its sides are in the ratio 6:8:10
Work out the area of the triangle in cm”.
B x W x = 2
Total marke: 4

Answers

Answer:

[tex]A=384\ cm^2[/tex]

Step-by-step explanation:

Let the sides of a triangle be 6x,8x and 10x.

Perimeter of the triangle, P = 96 cm

We need to find the area of the triangle.

P = sum of all sides

6x+8x+10x = 96

24x = 96

x = 4

Sides are :

6x = 6(4) = 24 cm

8x = 8(4) = 32 cm

10x = 10(4) = 40 cm

Area,

[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2[/tex]

So, the area of the triangle be [tex]384\ cm^2[/tex].

Ok my bad last question anyways ❤️URGENT 25 EACH❤️

Answers

Answer:

angle ABC=72 degrees

Step-by-step explanation:

8x+6x+6x=180 degrees   (all triangles contain 180 degrees)

20x=180

x=9

angle ABC=8x or (8)(9)=72 degrees

Answer:

72°

Step-by-step explanation:

Angle A = 6x

Angle B = 8x

Angle C = 6x

The sum of all interior angles in a triangle is 180°, which means angles A, B and C add up to 180:

A + B + C = 180

substitute in the values for A B and C:

6x + 8x + 6x = 180

Simplify by combining like terms:

6x + 6x + 8x = 180

20x = 180

solve for x:

20x/20 = 180/20

x = 9

Since we know x = 9 and angle B = 8x, u can substitute in the value of x to find the value of angle B:

B = 8x

B = 8(9)

B = 72°

Un estudiante de álgebra ha ganado $100,000 en una lotería y desea depositarlos en cuentas de ahorros en dos instituciones financieras. Una cuenta paga 8%de interés simple pero los depósitos se aseguran sólo a $50,000. La segunda cuenta paga 6.4% de interés simple y los depósitos se aseguran hasta $100,000 determine si el dinero se puede depositar para que quede completamente asegurado y gane un interés anual de $7,500

Answers

Answer:

Si puede asegurarse, ya que la inversión en la cuenta bancaria que da un 8% anual, es menor a 100 000 y mayor que 500 000.

Step-by-step explanation:

Ci= 100 000 $

Cuenta #1 = 8% de interés simple. con depósitos de 50 000$.

La segunda para 6.4% con interés simple para depósitos de 100 000$

Determine si el dinero se puede depositar para que fenere un interés de 7500

7500 = C1(0.08)+C2(0.064)

C1+C2= 100 000

C2 = 100 000 -C1

7500 = C1(0.08)+(100 000 - C1)(0.064)

1100= 0.016 C1

C1= 68750$.
