To estimate a proportion of students with a grade point average of 3.7 and higher in a college, a random sample of 200 students was taken and the number of successes counted to be 35. The 95% confidence interval for a population proportion is:
Answer: [tex](0.1481323,\ 0.2018677)[/tex]
Step-by-step explanation:
The confidence interval for population proportion :
[tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex] , where n= sample size, [tex]\hat{p}[/tex] = sample proportion , z*= Critical z-value.
Let p = population proportion of successes.
Given: n= 200 , [tex]\hat{p}=\dfrac{35}{200}=0.175[/tex]
Critical z value for 95% confidence = 1.96
The 95% confidence interval for a population proportion is:
[tex]0.175\pm (1.96)\sqrt{\dfrac{(0.175)(1-0.175)}{200}}\\\\=\ 0.175\pm (1.96)\sqrt{0.000721875}\\\\= 0.175\pm (1.96)(0.0268677)\\\\=(0.175-0.0268677,0.175+0.0268677)\\\\= (0.1481323,\ 0.2018677)[/tex]
Required confidence interval: [tex](0.1481323,\ 0.2018677)[/tex]

Answer:
a - b2
Step-by-step explanation:
STEP 1 :
Trying to factor as a Difference of Squares:
1.1 Factoring: a-b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : a1 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares
Final result :
a - b2

A table is made using the following two patterns.
Pattern x: Starting number: 1, Rule: add 1
Pattern y: Starting number: 5, Rule: add 5
Complete the table for the given patterns.
x y
1 5
Answer:
The required table will be
x y
1 5
2 10
3 15
4 20
5 25
Step-by-step explanation:
We are given 2 patterns
Pattern x: Starting number: 1, Rule: add 1
Pattern y: Starting number: 5, Rule: add 5
We need to complete the table for given patterns
x y
1 5
The second number for x according to pattern will be: we will add 1 to the previous number i.e 1+1 =2
The third number for x according to pattern will be: we will add 1 to the previous number i.e 2+1 =3
The second number for y according to pattern will be: we will add 5 to the previous number i.e 5+5 =10
The third number for y according to pattern will be: we will add 5 to the previous number i.e 10+5 =15
So, the required table will be
x y
1 5
2 10
3 15

5. €1575 was shared among three people in the ratio 1:2:1/2
Calculate the smallest share.
Answer:
€225
Step-by-step explanation:
Given that:
1575 shared in the ratio 1 : 2 : 1/2
Total sum of ratio = (1 + 2 + 1/2) = 3 1/2
Ratio 1 amount :
(1 / 3.5) * 1575 = 450
Ratio 2 amount :
(2 / 3.5) * 1575 = 900
Ratio 1/2 amount :
(1/2 ÷ 3.5) * 1575 = 225
Smallest share = $225

Anjelica is using synthetic division to divide 2x3−9x2−21x+10 by x+2 .
Which answer is correct?
Answer:
B I the answer I just did the same question
Anjelica is using synthetic division to divide
[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]
Steps given in option B are correct
Given :
Divide the given expression
[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]
Apply synthetic division
In synthetic division , we write all the coefficient inside the division
then solve the denominator for x and write it outside
[tex]x+2=0\\x=-2[/tex]
so we write -2 outside the division sign
Take down first number 2 as it is . Then multiply with -2 and put it below the second number . Add it and write it down . Continue the process.
-2 2 -9 -21 10
0 -4 26 -10

a grid of a hundred square show 7 shaded squares what decimal number is represented
Answer:
0.07
Step-by-step explanation:
From the question, a given grid was divided into a definite number of squares with some of the squares shaded.
Total number of squares in the grid = 100
number of shaded squares in the grid = 7
Thus, 7 squares are shaded out of 100 square in the grid.
So that this can be expressed in fraction as;
[tex]\frac{number of shaded squares}{total number of squares}[/tex] = [tex]\frac{7}{100}[/tex]
= 0.07
The decimal number of the squares represented is 0.07.
