The school board claims that 85% of the over 1,600 families with children in their district send their
children to public school. Skeptical of this claim, a private school administrator takes a simple random
sample of 120 families with children in the district and asks them whether they send their children to
public school.
Assuming the school board's claim is correct, what is the probability that the administrator's results are
within 5 percentage points of the school board's 85% claim?
Answer:
P(0.8< p ^ <0.9)≈0.87
Step-by-step explanation:
trust me
The probability that the administrator's results are within 5 percentage points of the school board's 85% claim is approximately 0.919.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
To find the probability that the administrator's results are within 5 percentage points of the school board's 85% claim, we need to find the probability that the sample proportion of families sending their children to public school is between 80% and 90%.
We can use the normal approximation to the binomial distribution to calculate this probability. Since the sample size is large (n = 120) and the population proportion is not too close to 0 or 1 (p = 0.85), we can use the normal approximation.
The mean of the sampling distribution is the population proportion, which is 0.85 in this case. The standard deviation of the sampling distribution is given by the formula:
SD = √((p × (1 - p)) / n)
Plugging in the values, we get:
SD = √((0.85 (1 - 0.85)) / 120)
= √(0.01225 / 120)
= √(0.0001010417)
= 0.0101
Now we can use the normal distribution calculator to find the probability that the sample proportion is between 0.80 and 0.90. Plugging in the mean (0.85) and standard deviation (0.0101) and the upper and lower limits (0.80 and 0.90), we get a probability of 0.919.
Therefore, the required probability is approximately 0.919.

paz and her scout troop makes 325 granola bars for a fundraiser. four granola bars are put in each bag. paz says that there will not be any left over. find and correct her mistake.
Answer:
Her mistake was in how many bags would be able to equally hold 4 bars.
325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.
A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.
Hope this helped!

Answer: 30
Step-by-step explanation:
1. Use the Pythagorean theorem ([tex]A^{2} +B^{2} = C^{2}[/tex])
[tex]18^{2} +24^{2} =C^{2} \\324 + 576 = C^{2} \\900 = C^{2} \\\sqrt{900} = \sqrt{C^{2} } \\30 = C\\[/tex]
Step-by-step explanation:
so in this case, you use the pythagoras theorem:
hypotenuse= opposite squared + adjacent squaredsince we don't have a hypotenuse, let's name is H
soo it will be
H= 18 squared + 24 squared
H = 324+ 576
H= 900
so you find the square root of 900 which is 30
so, therefore the answer is 30
Function g is an exponential function passing through points (3,-53) and (5,-41). Which statement is true over the interval [3,5]?
Answer: The function is increasing in the given interval.
Step-by-step explanation:
The options are not given, so i will answer in a general way.
We have an exponential function g(x) such that:
g(3) = -53
and
g(5) = -41
From this we can only conclude that in the interval [3, 5] the function is increasing, because g(5) > g(3) and the general form of a exponential function is:
g(x) = A*(r)^x + C
Notice that we have two equations and 3 variables in the equation, this means that we can not find an exact solution for g(x) (we need the same number of independent equations than variables)
Then we can not conclude anything else for g(x)

Quick prints makes custom t-shirts. They charge $10 for each t-shirt ordered plus a $5 design fee. Which situation best represents y, the total cost to order x t-shirts?
Answer:
y = 10x+5
Step-by-step explanation:
The price of each T-shirt = $10
Design fee on each T-shirt = $5
We need to find the expression for the total cost. Let the total cost be y. So,
Let he has ordered x T-shirts. So,
y = 10x+5
Hence, this is the required solution.

Alexis had $25.00 to spend on amusement park she spent 25% of her money on games she spent 1/2 of her money on food she spent $6.00 on a stuffed animal. How much money did Alexis have left?
Answer:
Step-by-step explanation:
25% of $25 = 0.25×$25 = $6.25
½ of $25 = ½×$25 = $12.50
$25 - $6.25 - $12.50 - $6 = $0.25

Solve for the ? angle
Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50

The cash price of a bike is $3000. The bike can be bought on hire purchase by making a 25% down-payment and monthly payments of 125 for 2 years. The hire purchase is
A) $3000
B) $750
C) $ 3750
D) $125
Answer:
C) $3750
Step-by-step explanation:
We can start by calculating the down payment. To do this we can just simply calculate 25% of 3000, which equals 0.25*3000=7500. Now we can find out how much money it will cost to pay not including the down payment. $125 monthly for 2 years= $125 monthly for 24 months= 125*24= $3000. Finally we add the downpayment and the total cost of monthly payment to get $7500+$3000=$3750.

What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
There are two children in the Patel family.
They are twins of the same age.
Let x be the age of two children.
As they are twins so the age of children's is same.
The formula of range is highest minus lowest.
range = highest - lowest
Range=x - x
Range =0
Hence, the range of their ages is 0.
