Answer:
Step-by-step explanation:
Mean μ = 36
standard deviation σ = 10
n = 16
standard deviation of the group σ₁ = σ / √n
σ₁ = 10/ √16
= 10 / 4 = 2.5
σ₁ = 2.5
P ( x > 35 ) = 1 - P ( x < 35 )
P ( x < 35 ) = P( z < (35 - 36) / 2.5 ) = P( z < (35 - 36) / 2.5 )
= P( z < 0.4 )
= .3446
P ( x > 35 ) = 1 - .3446
= .6554 .

Answer: 18.9 or 18 9/10
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

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.

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.

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]

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

A player wins the jackpot by matching all five numbers drawn from white balls (1 through 16) and matching the number on the gold Mega Ball (1 through 12). What is the probability of winning the jackpot?
The probability of winning the Jackpot is:______
Answer:
1.) 38/87
2.) 1 / 56784
Step-by-step explanation:
Given the data :

The probability that a randomly selected single parent in the U S military is In the Army is:_______
P = number of required outcome/ Total possible outcomes
P(single parent) :
Number of required outcomes = (number of single parents in the army = 38000
Total number of single parents in the military = 87000
P(single parent in army) = 38000 / 87000 = 38/87

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
