Step-by-step explanation:
To convert percents to decimals, remove the percent and move the decimal point 2 to the left.
4 % = [tex]\frac{4}{100}= 0.40[/tex]
37% = 0.37
400% = 4.00 = 4
9% = 0.09
180% = 1.80
Answer:
400%=4.0 180%= 1.80 37%=.37 4%=.04 9%=0.09

The Magazine Mass Marketing Company has received 16 entries in its latest sweepstakes. They know that the probability of receiving a magazine subscription order with an entry form is 0.4. What is the probability that no more than a fourth of the entry forms will include an order
0.1998 is the probability that no more than 4 of the entry forms will include an order.
Given the following information:
Treat subscription order with an entry form as a success.
P(subscription order with an entry form) = 0.4
Then the number subscription order with an entry form follows a binomial distribution, where
[tex]P(X = x) = nC_xp^x(1-p)^{n-x}[/tex]
where n is the total number of observations, x is the number of success, p is the probability of success.
Here, n = 16
[tex]P (x \leq 4) = P(x = 0) + P (x = 1) + P(x = 2) + P(x = 3)[/tex]
= [tex]16C_00.4^0(1-0.4)^{16} + 16C_10.4^1(1-0.4)^{15} + 16C_20.4^2(1-0.4)^{14}+ 16C_30.4^3(1-0.4)^{13}[/tex]
= 0.00028 + 0.0030 + 0.150 + 0.0468
= 0.1998
0.1998 is the probability that no more than 4 of the entry forms will include an order.

Step-by-step explanation:
[tex]range \: is : max - min \\ the \: range \: is \: : 529 - 5 = 524. \\ regards \\ ♨Rage♨[/tex]
The range of the given data set comes to be 524.
The given data set is: 52, 24, 5, 72, 49, 529
What is the range of a data set?The range of a data set is the difference between the maximum and minimum value of that data set.
The maximum value of the given data set = 529
The minimum value of the given data set = 5
The difference between the maximum and minimum value of that data set=529-5 =524

The time it takes a printer to print a job is an Exponential random variable with the expectation of 15 seconds. You send a job to the printer at 4:00 pm, and it appears to be forth in line. What is the probability that your job will be ready before 4:01 pm
Answer:
0.56652
Step-by-step explanation:
Given that :
1 job takes 15 seconds
x jobs will take 60 seconds
15x = 60
x = 4
4 jobs take 60 seconds
μ = 4
Job is 4th in line :
Find the probability of ;
P(x ≥ 4) = 1 - [P(x ≥ 4) = 1 - [P(x < 3 ) + P(x < 2) + P(x < 1) + p(x < 0)]
P(μ, x) = [(e^-μ) * (μ^x)] ÷ x!
Using the poisson distribution calculator :
P(x< 3) = 0.19537
P(x< 2) = 0.14653
P(x< 1) = 0.07326
P(x< 0) = 0.01832
Hence,
P(x ≥ 4) = 1 - [P(x < 3 ) + P(x < 2) + P(x < 1) + p(x < 0)
= 1 - (0.19537 + 0.14653 + 0.07326 + 0.01832)
= 1 - 0.43348
= 0.56652

2) The perimeter of a rectangle is 52 feet.
The length and width are represented by
two consecutive even integers. Find the
dimensions of the rectangle .
Answer:
12 feet and 14 feet
Step-by-step explanation:
Let a and b be the length and width of a rectangle
a and b are consecutive even integers
a=x, b=x+2
perimeter=52
2*(a+b)=52
2*(x+x+2)=52
2x+2=26
2x=24
x=12
a=12
b=x+2=14
Answer:
dimensions of the rectangle are 12 ft by 14 ft
Step-by-step explanation:
Let's name our unknowns :
width = x and therefore, the length according to the information given will be of size x + 2 (consecutive even integer).
Then the perimeter (addition of all four sides of the rectangle) will be the sum:
x + (x + 2) + x + (x + 2) = 52
combining like terms:
4 x + 4 = 52
subtracting 4 on both sides
4 x = 52 - 4
4 x = 48
x = 48 / 4
x = 12
so the width is 12 feet and the length must be 2 feet larger, that is: 14 feet
Then the dimensions of the rectangle are 12 ft by 14 ft.

4/5 + 3/5 = 7/5
3.5 x 5 = 17.5
7/5 + 17.5
18.9 = 18 9/10
Answer:
decimal form: 18.9 Fraction Form: 18 9/10
Step-by-step explanation:
(4/5+3/5)+3.5 x 5=18.9
Add Parenthesis= 4/5 + 3/5 = 7/5
Put the numbers back together= 7/5 + 3.5 x 5
Turn the fraction into a decimal form: 7/5=1.4
Put the number back together= 1.4+3.5 x 5
Now you have to do PEMDAS: meaning you have to multiply first
3.5 x 5 = 17.5
Put the problems back together= 17.5+1.4=18.9

Complete Question
The scores on a psychology exam were normally distributed with a mean of 59 and a standard deviation of 6. About what percentage of sores were less than 53. The percentage of scores that were less than 53 was %. (Type an integer or a decimal.
Answer:
The value is [tex]P(X < 53) = 0.15866[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 59[/tex]
The standard deviation is [tex]\sigma = 6[/tex]
Generally the percentage that were less than 53 is mathematically represented as
[tex]P(X < 53) = P(\frac{X - \mu }{\sigma } < \frac{ 53 - 59 }{ 6 } )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(X < 53) = P(Z < -1 )[/tex]
Generally the probability of (Z < -1 ) is
[tex]P(Z < -1 ) = 0.15866[/tex]
=> [tex]P(X < 53) = 0.15866[/tex]

Which of the following are partial products for 43 × 17? Choose all that apply. A. 3 B. 21 C. 28 D. 40 E. 400
Answer:
B. 21
E. 400
Step-by-step explanation:
Partial product of two digits number is the multiplication of the sum of place values of digits.
43 × 17
= (40 + 3) × (10 + 7)
To remove the parenthesis
= 40 × 10 + 40 × 7 + 3 × 10 + 3 × 7
Multiplying each pair separately
40 × 10 = 400
40 ×7 = 280
3 × 10 = 30
3 × 7 = 21
The partial product of 43 × 17 is
400 + 280 + 30 + 21 = 731
43 × 17 = 731
The answer is
B. 21
E. 400

Traveling between two campuses of a university in a city via shuttle bus takes, on average, 28 minutes with a standard deviation of 5 minutes. In a given week, a bus transported passengers 100 times. The probability that the average transport time was bigger than 27 minutes is
Answer: 0.9772
Step-by-step explanation:
Let X be a random variable that represents the transport time .
We assume X is normally distributed with a mean [tex]\mu=28\text{ minutes}[/tex] and a standard deviation [tex]\sigma=5\text{ minutes}[/tex].
Sample size : n= 100
The probability that the average transport time was bigger than 27 minutes:
[tex]P(\overline{X}>27)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{27-28}{\dfrac{5}{\sqrt{100}}})\\\\=P(Z>\dfrac{-1}{\dfrac{5}{10}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>-2)=P(Z<2)\ \ \ [P(Z>-z)=P(Z<z)]\\\\=0.9772\ \ \ [\text{By p-value table}][/tex]
Hence, the required probability =0.9772
