Scientists follow specific processes in order to determine valid explanations and conclusions from scientific data. Students gra

duating from Rydell High School in 2010 were asked to fill out an exit survey the last week of school. When students were asked to compare language arts courses with science courses, 20% of males reported preferring language arts and 80% reported preferring science. For females, 90% reported preferring language arts and 10% reported preferring science. Which of the following would be a valid conclusion based on the data from this study? a. Females are better at language arts than males, and males are better at science than females b. Females at Rydell High School are better at language arts than males at RHS, and males at RHS are better at science than females at RHS c. Females at Rydell High School prefer language arts courses to science courses, and males at Rydell High School prefer science courses to language arts courses d. For a specific graduating class at Rydell High School, the majority of male students preferred science courses over language arts, and the majority of female students preferred language arts courses over science

D is the answer. You cannot say that anyone is good at anything because it doesn't say that. And they were surveying the class of 2010

Answer is: d. For a specific graduating class at Rydell High School, the majority of male students preferred science courses over language arts, and the majority of female students preferred language arts courses over science.

a. is not correct because this survey is about preference of students, not there grades.

b. is same as a.

c. is not correct because this survey is only about one genration of students (specific genration) and not about whole school.

What causes the earth’s magnetic field? A. currents in the earth’s liquid-metal outer core B. the mineral composition of the ear
S_A_V [24]
The magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core. So your answer is A

A chemist prepares a solution of sodium chloride by measuring out 25.4 grams of sodium chloride into a 100. mL volumetric flask
mr_godi [17]

Answer:

The concentration in mol/L =  4.342 mol/L

Explanation:

Given that :

mass of sodium chloride = 25.4 grams

Volume of the volumetric flask = 100 mL

We all know that the molar mass of sodium chloride NaCl = 58.5 g/mol

and number of moles = mass/molar mass

The number of moles of sodium chloride = 25.4 g/58.5 g/mol

The number of moles of sodium chloride = 0.434188 mol

The concentration in mol/L = number of mol/ volume of the solution

The concentration in mol/L = 0.434188 mol/ 100 × 10⁻³ L

The concentration in mol/L =  4.34188 mol/L

The concentration in mol/L =  4.342 mol/L

Describe what you know about this chemical formula: 4CO2
Setler79 [48]

Answer:i hope im not too late

Explanation:

4CO2 also known as 4CO2 is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. It also helps trap earths heat inside the earth so i doesnt escape back to outer space.

yourwelcome goodluck ill peel my eyes out if need help again- an 8th grader :p

The correct mathematical expression for finding the molar solubility (s) of sn(oh)2 is:
lara [203]
Answer is: Ksp = 4s³.
Balanced chemical reaction (dissociation) of strontium hydroxide:
Sr(OH)₂(s) → Sr²⁺(aq) + 2OH⁻(aq).
Ksp(Sr(OH)₂) = [Sr²⁺]·[OH⁻]².<span>
[</span>Sr²⁺] = s.<span>
[</span>OH⁻] = [Sr²⁺] = 2s<span>
Ksp = (2s)² · x = 4s³.
Ksp is the solubility product constant for a solid substance dissolving in an aqueous solution.
[</span>Sr²⁺] is equilibrium concentration of iumcations.<span>
[</span>OH⁻] is equilibrium concentration of hydroxide anions.
