Answer:

a.7,8

b .first write the number from ascending to descending

then find the number which is in the middle .they are 2 numbers so find their average.

7+5/2=12/2=6

c .3+7+2+4+7+5+7+1+8+8/10=52/10=5.2

d .subtract from the bigger number the small number

Solution,

Given data=3, 7 , 2 , 4, 7, 5, 7, 1, 8, 8

a.Mode= 7 because it has more frequency in comparison to others.

b.Arranging the data in ascending order:

: 1,2,3,4,5,7,7,7,8,8

N(total number of items)=10

Median=(N+1/2)th item

 = (10+1/2)th item

 = (11/2)th item

 = 5.5th item

Again,

5th item+6th item/2

 = 5+7/2

=12/2

= 6

c. summation FX=52

 N=10

Mean= summationfx/N

 =52/10

 =5.2

D. Range= highest score- lowest score

 = 8-1

 =7

Hope it helps

Good luck on your assignment

Find each absolute value | 4+2i | | 5-i | | -3i |

galina1969 [7]

How to get answer for number 1: | 4+2i |

$\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=4,\:b=2\\=\sqrt{4^2+2^2}\\Refine\\=\sqrt{20}\\\sqrt{20}=2\sqrt{5}\\=2\sqrt{5}$

How to get answer for number 2: | 5-i |

$\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=5,\:b=-1\\=\sqrt{5^2+\left(-1\right)^2}\\=\sqrt{26}$

Number 3 how to get answer: | -3i |

$\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=0,\:b=-3\\=\sqrt{0^2+\left(-3\right)^2}\\Refine\\=\sqrt{9}\\\sqrt{9}\\\mathrm{Factor\:the\:number:\:}\:9=3^2\\=\sqrt{3^2}\\\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a\\\sqrt{3^2}=3\\= 3$

Hey, Guys, can someone help me with this

Lunna [17]

Answer:

A length=24ft, width=15ft

Step-by-step explanation:

the side AB have x values of 5 and the side with CD have x values of 10 so the width from b to d or a to c is 5 so the width of the drawing is 5cm

the bottom side AC has y values of 8 and the top side BD has y values of 16 so they are 8 apart so the length of the rectangular drawing is 8cm

then the scale says that 1 cm = 3 ft so multiply the length and width each by 3 to get the answer that the length of the sail is 24ft and the width is 15ft

Hope this helps! :)

Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10. In what percentile is

vlabodo [156]

Given:
μ = 70, the mean
σ = 10, the standard deviation

The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.

Answer: 30th
