The school nurse took care of five students on Monday and four of the five students had a cough. The school nurse determined that 80% of the students in her school were coming down with colds. Which of the following would best describe why her conclusion was invalid?

Answers

Answer 1

Answer:

It is not valid because she only saw 5 students and that's not a large enough sample for the whole school.

Step-by-step explanation:

While 4/5 IS 80%, the nurse assumed that 80% of ALL of the students in the school were coming down with colds. This is not true since only 4 students had colds. If she were specific and said that 4/5 students who visited her on Monday were 80% coming down with colds, she'd be right. But she isn't since she's assuming it's 80% of the whole school's population of students.

Answers

Answer:

14 and 16

Step-by-step explanation:

They are the ONLY  consecutive even numbers

And also

x and (x+2)

x(x+2)=224 ( product of a number and the consecutive of that number)

x ²+  2x-224=0

(x+16)(x-14) =0

x=-16 or 14

In this case 14 and (14+2)    14 and 16

 

 

The  integers are either 14 and 16 or -14 and -16.

PLEASE HELP ME FOR REAL!!!

Answers

Answer:

I got 278 5/8

Step-by-step explanation:

the question stated square inches which I referred

to as area. You multiply both rectangles than add them together. I may be wrong but I hope this gives you a lead! :)

The total square inches of construction paper does Matthew need for his project is,

⇒ 278.63 inches²

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Matthew is cutting construction paper into rectangles for a project.

And, He needs to cut one rectangle that is 12 inches x 14 1/4 inches.

He needs to cut another rectangle that is 10 1/2 inches by 10 1/4.

Hence, We get;

Area of first rectangle = 12 x 14 1/4

                                  = 12 x 57 / 4

                                  = 171 inhces²

And, Area of second rectangle = 10 1/2 x 10 1/4

                                                = 21/2 x 41/4

                                                = 107.63 inches²

Hence, The total square inches of construction paper does Matthew need for his project is,

⇒ 171 + 107.63 inches²

⇒ 278.63 inches²

un refresco tiene una concentración de 3.8 x 10-4 de iones H+. determina el valor de PH de ese refresco​

Answers

Answer:

El pH del refresco es 3.42.

Step-by-step explanation:

Se puede calcular el pH del refresco usando la siguiente fórmula:

[tex]pH = -log([H^{+}])[/tex]

En donde:

[H⁺]: es la cocentración de los iones H⁺ de la solución

Entonces, el pH es:

[tex]pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42[/tex]

El resutlado obtenido nos permite concluir que ese refresco es ácido.

Por lo tanto, el pH del refresco es 3.42.

Espero que te sea de utilidad!

Usando su fórmula, se encuentra que el valor de PH de ese refresco​ es dado por 3.42.

Cual es la fórmula para el valor de PH?

Es dada por:

[tex]pH = -\log{H^{+}}[/tex]

Onde [tex]H^+[/tex] es la concentración.

En este problema, hay que la concentración es de [tex]H^+ = 3.8 \times 10^{-4}[/tex], por eso:

[tex]pH = -\log{H^{+}}[/tex]

[tex]pH = -\log{3.8 \times 10^{-4}}[/tex]

[tex]pH = 3.42[/tex]

El valor de PH de ese refresco​ es dado por 3.42.

An elephant at an animal sanctuary weighs 5.5 tons. He receives a daily nutritional supplement. The instructions say to give 1 fluid ounce of supplement for every 250 pounds of body weight. How many fluid ounces of supplement should the elephant receive? no options I need to type it in.

Step-by-step explanation:

It's important to keep in mind that 1 ton is 2,000 pounds.

5 x 2,000 = 10,000 pounds.

You have to add 1,000 pounds because of the '.5' at the end of the 5. That leaves you with 11,000 pounds.

Now, you have to divide by 250 to find how many fluid ounces you need.

Answers

Answer:

- 6°F

Step-by-step explanation:

Given :

Temperature at 6:00 = 15°F

Temperature dropped by 9°F by 8:00

Temperature by 8:00 = 15°F - 9°F = 6°F

Temperature dropped another 12°F by 11:00

Hence, Temperature at 11:00 will be :

6°F - 12°F = - 6°F

Temperature at 11:00 = - 6°F

How to find Gradient and y intercept

Answers

Gradient:

Find two points on the line and with those two points, calculate the difference in height(y coordinates) divided by the difference in width(x coordinates). If you get a positive value, then your line will be uphill.

Y-intercept:

Use y=mx+b
Find the slope first using the slope formula which is y2-y1 OVER x2-x1. Once you have that, take a point from the line and substitute the x and y coordinates along with the slope into y=mx+b.

So if your slope was 2/1 and your point was (4,8), it would be:

8=2(4)+b
8=6+b
*subtract 6 from both sides*
b=2
