Alma is estimating the proportion of students in her school district who, in the past month, read at least 1 book. From a random sample of 50 students, she found that 32 students read at least 1 book last month. Assuming all conditions for inference are met, which of the following defines a 90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month?
a. 32 + or - 1.645 underroot(32)(18)/50.
b. 32 + or - + 1.96 underroot(32)(18)/50.
c. 0.64 + or - 1.282 underroot(0.64)(0.36)/50.
d. 0.64 + or - 1.645 underroot(0.64)(0.36)/50.
e. 0.64 + or - 1.96 underroot(0.64)(0.36)/50.
Answer:
[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex], option D
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
From a random sample of 50 students, she found that 32 students read at least 1 book last month.
This means that [tex]n = 50, \pi = \frac{32}{50} = 0.64[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
Confidence interval:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex]
So the correct answer is given by option D.
Johnny wants to invest $10,000 at 4.5% interest rate compounded quarterly, How much will he have after 38 years?
Answer:
a= $54764.26
Step-by-step explanation:
r=R/100
r=4.5/100
r=0.045 rate per year
A = P(1 + r/n)nt
A = 10,000.00(1 + 0.045/4)(4)(38)
A = 10,000.00(1 + 0.01125)(152)
A = $54,764.26

Answer:
choice 1: m = 6 1/2
Step-by-step explanation:
m - 2 1/2 = 4
add 2 1/2 to each side of the equation:
m - 2 1/2 + 2 1/2 = 4 + 2 1/2
m = 6 1/2

Shannon is creating a scale drawing of her classroom. If she is using the scale 1/2 inch = 1 foot and the room model is 10 inches by 15 inches, what are the dimensions of the actual room. Please help me!
Answer:
30 foot by 20 foot
Step-by-step explanation:
1 inch = 10 inch
2 foot = d foot
Cross products: 1xd=2x10

1 inch = 15 inch
2 foot = d foot
Cross products: 1xd=2x15
d=30foot

You now have $4000. You will toss a fair coinup tofour times. Before each toss you can bet any amount of your money (including none) on the outcome of the toss. If heads comes up, you win the amount you bet. If tails comes up, you lose the amount you bet. Your goal is to reach $6000. It turns out that you can maximize your chance ofreaching$6000 by betting either the money you have on hand or $6000minus the money that you have on hand, whichever is smaller. Use simulation to estimate the probability that you will reach your goal with this betting strategywith the initial budget $4000.
Answer:
Since we want to bet the smaller amount, $6000 - budget, each time, we will be betting $2000 dollars each time. We know the odds of landing on heads with a coin is a %50 chance. Now if we get heads we can win. If we do not get heads we are left with $2000. Follow the betting equation again. $6000 - $2000 = $4000. We do not have $4000 so we will bet $2000. Once again we have a %50 chance of winning. If we win we will have $4000. If we loose, we will be left with nothing. If we were to loose, we would no longer be able to reach our goal because lack of money. Now lets say we won. We would have $4000 again so we would have to repeat like before. We would bet $2000 and if we win, we reach the goal. If we lost, we would also have to repeat steps before. This means the game could be over in 1 flip but could go on forever.

Judy built a rectangular patio that is 9 units wide and has a perimeter of 40 units.
Which image correctly labels the given information?
Answer:
See attachment for image
Step-by-step explanation:
Given
[tex]Width = 9[/tex]
[tex]Perimeter = 40[/tex]
Required
The image that illustrates the patio
The question is incomplete as the possible images are not given. So, I will attach an image that illustrates the scenario.
But first, the length of the patio must be calculated using perimeter formula
[tex]Perimeter = 2 *(Length + Width)[/tex]
[tex]40 = 2 *(Length + 9)[/tex]
Divide both sides by 2
[tex]20 = Length + 9[/tex]
Solve for Length
[tex]Length = 20 - 9[/tex]
[tex]Length = 11[/tex]
This implies that the dimension of the patio is 11 units by 9 units (See attachment)

Triangle ABC has vertices A(-4,-1), B(-3,-5), C(-1, -1). Graph and label the vertices of ABC
and its image A'B'C' after translating it to 4 units right and 3 units up. Choose the correct
ordered pairs of the image A'B'C'.
(2 Points)
O A'(4.1), B (3,5), C' (1.1)
O A'(0,2), B(1, -2). C'(3.2)
O A'(0.2), B (1,2), C'(-3,-2)
Answer:
A'(0,2), B(1, -2). C'(3,2)
Step-by-step explanation:
Given
[tex]A = (-4,-1)[/tex]
[tex]B = (-3,-5)[/tex]
[tex]C =(-1,-1)[/tex]
Solving (a); Graph and Label ABC
See attachment for graph
Solving (b): Graph and Label A'B'C'
Translation:
4 units right
3 units up
4 units right
The rule is:
[tex](x,y) \to (x + 4,y)[/tex]
So, we have:
[tex]A = (-4,-1)[/tex] ==> [tex](-4+4,-1) =(0,-1)[/tex]
[tex]B = (-3,-5)[/tex] ==> [tex](-3+4,-5) =(1,-5)[/tex]
[tex]C =(-1,-1)[/tex] ==> [tex](-1+4,-1) =(3,-1)[/tex]
3 units up
The rule is:
[tex](x,y) \to (x,y+3)[/tex]
So, we have:
[tex](0,-1)[/tex] ==> [tex]A' =(0,-1+3) = (0,2)[/tex]
[tex](1,-5)[/tex] ==> [tex]B' =(1,-5+3) = (1,-2)[/tex]
[tex](3,-1)[/tex] ==> [tex]C' =(3,-1+3) = (3,2)[/tex]
The coordinates of A' B' and C' are:
A'(0,2), B(1, -2). C'(3,2)

Find the length of chord AD
9514 1404 393
Answer:
AD = 15
Step-by-step explanation:
The products of the segment lengths are the same.
(x -2)(x +7) = 4(2x -1)
x^2 +5x -14 = 8x -4
x^2 -3x -10 = 0
(x -5)(x +2) = 0
The positive solution is x=5.
Chord AD is ...
(x -2) +(x +7) = 2x +5 = 2(5) +5 = 15
Chord AD is 15 units long.

Mr Baxter deposits 2,000 in an account that earns %5 simple interest how much is mr Baxter investment after 8 years?
Answer:
$2,800
Step-by-step explanation:
The formula for simple interest is I = PRT, where I is the interest (earned or paid), P is the principal amount invested/borrowed, R is the rate in decimal form, and T is the time in years.
I = (2000)(0.05)(8)
I = $800
Then we add that to the principal to get $2,800

Joey made a deposit into an account that earns 6% simple interest. After 3 years, Joey earned $400. How much was Joey's initial deposit?
I = PRT
400 = P(0.06)(3)
400 = 0.18P
P = $2,222. 22
