Select all of the expressions that have the same value as 892 ÷ 8
8920÷80
894÷10
89.2÷0.08
8.92÷0.8
0.892÷0.008
Answers
Answer:
8920÷80 and 0.892÷0.008
Step-by-step explanation:
To get the expressions that have the same value as 892 ÷ 8, we can either divide or multiply both values by the same constant.
Multiplying both values by 10
892 ÷ 8
= 892/8
= 892/8 * 10/10
= 8920/80
Divide both by 10
892÷8
= (892÷10)÷(8÷10)
= 89.2÷0.8
Divide both by 1000
892÷8
= (892÷1000)÷(8÷1000)
= 0.892÷0.008
Hence the expressions that are similar are 8920÷80 and 0.892÷0.008

Suppose you go shopping for a new futon bed for your room. The model you really like happens to be on sale for $1125. It's original price is $1200. What percent of the original price will you save if you purchase it?
Answers
Answer:
9.375% rounded 9%
Step-by-step explanation:
so if the original price is 1200 that is equal to 100% so if 1200=100% then to get ten percent of 1200 u would divide 1200 by 10 which gets you 120 and if the sale price is 1125 then u do 1125 divide by 120 because that is 10% so that gives you 9.357 and you add you percentage on and there is your anwser hope this helped ;)

MNM Corporation gives each of its employees an aptitude test. The scores on the test are normally distributed with a mean of 75 and a standard deviation of 15. A simple random sample of 25 is taken from a population of 500.
a. What are the expected value, the standard deviation, and the shape of the sampling distribution of?
b. What is the probability that the average aptitude test in the sample will be between 70.14 and 82.14?
c. What is the probability that the average aptitude test in the sample will be greater than 82.68?
d. What is the probability that the average aptitude test in the sample will be less than 78.69?
e. Find a value, C, such that P(( x>C) = .015.
Answers
Answer:
a) The expected value is 75, the standard deviation is 3 and the shape is approximately normal.
b) 0.9387 = 93.87% probability that the average aptitude test in the sample will be between 70.14 and 82.14.
c) 0.0052 = 0.52% probability that the average aptitude test in the sample will be greater than 82.68.
d) 0.8907 = 89.07% probability that the average aptitude test in the sample will be less than 78.69.
e) C = 81.51.
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].
The scores on the test are normally distributed with a mean of 75 and a standard deviation of 15.
This means that [tex]\mu = 75, \sigma = 15[/tex]
a. What are the expected value, the standard deviation, and the shape of the sampling distribution of?
By the Central Limit Theorem, it will be approximately normal, with expected value [tex]\mu = 75[/tex] and standard deviation [tex]s = \frac{15}{\sqrt{25}} = 3[/tex].
b. What is the probability that the average aptitude test in the sample will be between 70.14 and 82.14?
This is the pvalue of Z when X = 82.14 subtracted by the pvalue of Z when X = 70.14.
X = 82.14
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{82.14 - 75}{3}[/tex]
[tex]Z = 2.38[/tex]
[tex]Z = 2.38[/tex] has a pvalue of 0.9913.
X = 70.14
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{70.14 - 75}{3}[/tex]
[tex]Z = -1.62[/tex]
[tex]Z = -1.62[/tex] has a pvalue of 0.0526
0.9913 - 0.0526 = 0.9387
0.9387 = 93.87% probability that the average aptitude test in the sample will be between 70.14 and 82.14.
c. What is the probability that the average aptitude test in the sample will be greater than 82.68?
This is 1 subtracted by the pvalue of Z when X = 82.68. So
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{82.68 - 75}{3}[/tex]
[tex]Z = 2.56[/tex]
[tex]Z = 2.56[/tex] has a pvalue of 0.9948.
1 - 0.9948 = 0.0052
0.0052 = 0.52% probability that the average aptitude test in the sample will be greater than 82.68.
d. What is the probability that the average aptitude test in the sample will be less than 78.69?
This is the pvalue of Z when X = 78.69. So
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{78.69 - 75}{3}[/tex]
[tex]Z = 1.23[/tex]
[tex]Z = 1.23[/tex] has a pvalue of 0.8907.
0.8907 = 89.07% probability that the average aptitude test in the sample will be less than 78.69.
e. Find a value, C, such that P(( x>C) = .015.
This is X when Z has a pvalue of 1 - 0.015 = 0.985. So X when Z = 2.17.
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]2.17 = \frac{X - 75}{3}[/tex]
[tex]X - 75 = 3*2.17[/tex]
[tex]X = 81.51[/tex]
So C = 81.51.

the side of the square is 16cm so the diameter of the circle is 16cm
The radius of the circle is 8cm since the radius is half the diameter
To A=πr^2 in which r=8
so A=πr^2=π·82≈201.06193
Diameter = 16cm
QuestionArea of the circle
Way to do#Find the radius first to get the area
radius = diameter : 2
radius = 16cm : 2
radius = 8cm
#After that, find the area
Area = π × r²
Area = π × (8cm)²
Area = π × 64cm²
Area = 3.14 × 64cm²
Area = 200.96cm²
Noteπ (phi) = 22/7 or 3.14
r = diameter : 2
Area of circle = π ×r²
Perimeter of the circle = π×d
r = radius
d = diameter
