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.

HELP NEEDED!!! 20 POINTS FOR A ANSWER AND EXPLANATION ON QUESTION #2! I cant figure this out help me please

Answers

Step-by-step explanation:

Start at the orgin.

The y intercept in the equation is -1 so I would shift 1 unit down to the orgin at (0,-1)

Then at the point, since the slope is -4. I would go down -4 units then go over 1 unit to the right.. So the next point would be (1,-5) then so on and so on.

You can check if your graph is correct by writing out specific points on the linear equation and making sure there slope is equal to -4.

Persephone and Madison are sharing a coloring book with 48 pages in it. Persephone can color one page in 8 minutes. Madison can color one page in 6 minutes. They color every page in the book.

Answers

Answer:

[tex]Persephone = 27\frac{3}{7}[/tex]

[tex]Madison = 20\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]Pages = 48[/tex]

[tex]P=8\ mins[/tex] --- Persephone

[tex]M = 6\ mins[/tex] --- Madison

The question is incomplete, however a possible question could be:

To determine the number of pages colored by each of them

First, we determine the ratio of time spent by each:

[tex]P : M = 8 : 6[/tex]

The number of pages covered by Persephone is:

[tex]Persephone = \frac{P}{P + M} * Pages[/tex]

[tex]Persephone = \frac{8}{8+6} * 48[/tex]

[tex]Persephone = \frac{8}{14} * 48[/tex]

[tex]Persephone = \frac{384}{14}[/tex]

Simplify

[tex]Persephone = 27\frac{3}{7}[/tex]

This implies that Madison colors the remaining pages.

This is calculated as:

[tex]Madison = Pages - Persephone[/tex]

[tex]Madison = 48 - \frac{384}{14}[/tex]

Take LCM

[tex]Madison = \frac{48 * 14 - 384}{14}[/tex]

[tex]Madison = \frac{288}{14}[/tex]

Simplify

[tex]Madison = 20\frac{4}{7}[/tex]

Jacob has a rectangular garden with an area of 56 square feet.The length of the garden is 8 feet.What is the width if the garden?

Answers

Answer:

The width of the garden is 7 feet.

Step-by-step explanation:

If the area is 56 feet, and the length is 8 feet, we can put this into the area equation.

Area = width * length

A = wl

Substitute variables.

56 = 8w

Divide by 8.

7 = w, or w = 7.

The width of the garden is 7 feet.

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet. A. B. C. D.

Answers

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3
