Answers

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]

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

Answers

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.

Answers

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

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

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

Answers

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

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 .

Answers

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.
