Answer:

The answer is [10+(9x3]+4 and 5x4+(7x3).

Step-by-step explanation:

I can't really explain, but if you add 10+4, it'll be 14.

If you multiply 9x3, it'll be 27.

So, if you add 27+14, it will be 41.

For the second answer:

If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.

Find the length and width of a rectangle with an area of 2x^2+x-3

nasty-shy [4]

2x^2 + x -3 can be factorised

[2x + 3][x - 1] 

As length times width = area 

one possible set of measurements are 

length = [2x + 3] 
width = [x-1]

snow_lady [41]

Answer:

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5

Step-by-step explanation:

Explanation:-

Given Population mean ' μ'= 16

Standard deviation of Population 'σ' = 2

Let 'x' be the Random Variable of Normal distribution

Given x = 13 foot balls

The z score for a wide receiver who dropped 13 footballs over the course of a season

$Z = \frac{x-mean}{S.D}$

$Z = \frac{13 -16}{2} = \frac{-3}{2} = -1.5$

Final answer:-

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5

An ice cream cone is filled with vanilla and chocolate ice cream at a ratio of 2:3. If the diameter of the cone is 2 inches and

Tpy6a [65]

Volume of the cone is ⅓πr²h where r= radius=1 in and h=5 in, so volume is 5π/3 cu in. Divide this into 5 equal parts, one part=π/3, so chocolate is 3 parts=π cu in=3.1 cu in = 3.1 cu in approx, answer C.
