Step-by-step explanation:
The point estimate is the best guess of the true parameter. It is an estimate of a population parameter and it is a single value of statistics.
The sample proportion [tex]\hat p[/tex] is the point estimate of the population proportion p
Given that
The sample mean = 274; &
The sample size = 992

A 400g loaf of white bread contains 228 g of flour. An 800 g loaf of brown
bread contains 472 g of flour. Which loaf contains a higher percentage of flour?
Answers
Answer:
The loaf of brown bread contains a higher percentage of flour.
Step-by-step explanation:
To find the percentage of flour, we divide the amount of flour by the weight of the bread, and then multiply by 100. So
400g loaf of white bread:
228g of flour
[tex]P = \frac{228*100}{400} = 57\%[/tex]
57% of flour
800g loaf of brown bread:
472g of flour
[tex]P = \frac{472*100}{800} = 59\%[/tex]
59% of flour, so, a higher percentage

Answers
Answer:
69 students
Step-by-step explanation:
Step one:
number of students = 75
percentage absebt= 8%
Find the value of 8% absent
=8/100*75
=0.08*75
=6 students
Number present= Total students- number absent
Number present= 75- 6
Number present= 69
Hence there are 69 students present
Find the percent change to the nearest whole percent. from 45 feet to 95 feet.
Answers
Answer:
211%
Step-by-step explanation:
To calculate the percentage change between these two numbers we need to divide the end result from the initial starting point. Once we do this we need to multiply the product by 100 to get the percentage value.
95 / 45 = 2.11111
2.11111 * 100 = 211.11%
Finally, we can see that the percentage change from 45 ft. to 95 ft. is 211.11%. If we round this to the nearest whole percent it would be a change of 211%

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = 2x³ + 1
For x = 1, 2, 3,
y = 2 + 1 = 3
y = 2 x 2³ + 1 = 2 x 8 + 1 = 17
y = 2 x 3³ + 1 = 2 x 27 + 1 = 54 + 1 = 55
The rate of change.
Between 3 and 17 = 17 - 3 = 14
Between 17 and 55= 55 - 17 = 38
This means the equation is not linear.
y = 3x
For x = 1, 2, 3,
y = 3 x 1 = 3
y = 3 x 2 = 6
y = 3 x 3 = 9
The rate of change.
Between 3 and 6 = 6 - 3 = 3
Between 6 and 9 = 9 - 6 = 3
This means the equation is linear.
y = x/5
For x = 1, 2, 3,
y = 1/5
y = 2/5
y = 3/5
The rate of change.
Between 1/5 and 2/5 = 2/5 - 1/5 = 1/5
Between 2/5 and 3/5= 3/5 - 2/5 = 1/5
This means the equation is linear.
Thus,
y = 2x³ + 1 is a linear equation.
y = 3x is not a linear equation.
y = x/5 is a linear equation.

Answers
Answer:
[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(5n^2\:-\:4nm\:-\:9m^2\right)\:+\:\left(7n^2\:+\:4nm\:+8m^2\right)[/tex]
Remove parentheses: (a) = a
[tex]=5n^2-4nm-9m^2+7n^2+4nm+8m^2[/tex]
Group like terms
[tex]=5n^2+7n^2-4nm+4nm-9m^2+8m^2[/tex]
Add similar elements: [tex]5n^2+7n^2=12n^2[/tex]
[tex]=12n^2-4nm+4nm-9m^2+8m^2[/tex]
Add similar elements: [tex]-4nm+4nm=0[/tex]

Add similar elements: [tex]-9m^2+8m^2=-m^2[/tex]

In order to study the relationship between playing football and traumatic brain injuries, researchers placed accelerometers in the helmets of many high school football teams. Accelerometers measure the amount of hits that boys playing high school football absorb during a season. Suppose the average number of hits absorbed by a helmet during a season was 355 hits with a standard deviation of 80 hits. What is the probability on a randomly selected team of 48 players that the average number of head hits per player is between 340 and 360 hits
Answers
Answer:
56.96% probability on a randomly selected team of 48 players that the average number of head hits per player is between 340 and 360 hits
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a single player:
[tex]\mu = 355, \sigma = 80[/tex]
For the sample mean(of 48 playes).
[tex]n = 48, s = \frac{80}{\sqrt{48}} = 11.547[/tex]
What is the probability on a randomly selected team of 48 players that the average number of head hits per player is between 340 and 360 hits?
This is the pvalue of Z when X = 360 subtracted by the pvalue of Z when X = 340. So
X = 360
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{360 - 355}{11.547}[/tex]
[tex]Z = 0.43[/tex]
[tex]Z = 0.43[/tex] has a pvalue of 0.6664
X = 340
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{340 - 355}{11.547}[/tex]
[tex]Z = -1.30[/tex]
[tex]Z = -1.30[/tex] has a pvalue of 0.0968
0.6664 - 0.0968 = 0.5696
56.96% probability on a randomly selected team of 48 players that the average number of head hits per player is between 340 and 360 hits

The balance paid in 6
Monthly payment is $676
First , let's find the amount financed:
[tex]A=4400.\frac{90}{100} =3960[/tex]
The number of payments per year (n) are 6.
The time in years is half a year.(6 months)
The installment payment is $676.
The total amount paid is
[tex]676.6=4056[/tex]
Then, we subtract to obtain the finance charge
[tex]4056-3960=96[/tex]
