Anna surveyed 300 of the students in her school about their favorite color. 186 students said their favorite color was red. What percentage of the surveyed students said their favorite color was red?
Answer:_________
PLEASE HELP ME!!!
Answers
Answer:
62%
Step-by-step explanation:
I took a fraction and made a decimal which was made into a percentage.
186 ÷ 300 = .62
Check: 62% • 300 = 186
The survey Anna conducted has 62% of students whose favorite color is red.
What is percentage?The percentage is the value per hundredth. Percentages can be converted into decimal form by dividing them by hundred, Percentage can also be represented as a fraction.
Given that 186 out of 300 students Anna surveyed chooses red as their favorite color.
The percentage of students whose favorite color is red is no. of students whose favorite color is red divided by the total no. of students multiplied by hundred which is,
= (186/300)×100.
= 186/3.
= 62%.

Answer:
x = 6√2, y = 6
Step-by-step explanation:
This is an isosceles triangle as one angle measures 45° and the other is a right angle, so it measures 90°.
Therefore, you know that y will equal 6.
You have to multiply a by √2 to find x.
6 x √2 = 6√2
Hope this helps!
Answer:
x = 6[tex]\sqrt{2}[/tex]
y = 6
Step-by-step explanation:
in a 45-45-90 triangle the two legs are equal, so XY = YZ
also, the leg to hypotenuse ratio is 1 : [tex]\sqrt{2}[/tex]
so x = 6 · [tex]\sqrt{2}[/tex]

A group of scientists is conducting an experiment on the effects of media on children. They randomly select 100 children and randomly assign each child to one of four treatment groups. Each treatment group has a specific amount of screen time during a one-week time frame. The first group has no screen time, the second group has two hours of screen time, the third group has four hours of screen time, and the fourth group has six hours of screen time.
After the first week, the scientists conduct the same experiment, with the same subject groups, for three more weeks so that each group experiences each of the four treatments.

THANK YOU SO MUCH
Answers
Answer:
a=1
b= -6
c=48
Step-by-step explanation:
x^2=6(x-8)
x^2=6x-48
x^2-6x+48
a,b are the coefficients of x^2 and x
c is the constant value present
Therefore it is basically written as ax^2+bx+c
and comparing with the answer x^2-6x+48,
a=1, b= -6, c=48
Vitamin D is important for the metabolism of calcium and exposure to sunshine is an important source of vitamin D. A researcher wanted to determine whether osteoperosis was associated with a lack of exposure to sunshine. He selected a sample of 250 women with osteoperosis and an equal number of women without osteoperosis. The two groups were matched - in other words they were similar in terms of age, diet, occupation, and exercise levels. Histories on exposure to sunshine over the previous twenty years were obtained for all women. The total number of hours that each woman had been exposed to sunshine in the previous twenty years was estimated. The amount of exposure to sunshine was compared for the two groups.
Required:
a. Determine whether this is a controlled experiment or an observational study.
b. Identify the treatment variable.
Answers
Answer:
Vitamin D and Osteoporosis
a. This is an observational study. The researcher is trying to observe the two groups of women who suffer from osteoporosis. She did not apply any treatment on any group, as is the case with experimental researches.
b. The treatment variable is the amount of exposure to sunshine.
Step-by-step explanation:
This study is an observational research because the researcher lacks the control over the variables, especially the amount of exposure to sunshine. She is merely observing what has occurred previously. On the other hand, an experimental study will involve the application of some treatments to one group of women and then the recording of the effects. But in this case, the researcher merely recorded the effects that had occurred without applying any treatment to any group.
