Answer:

512

Step-by-step explanation:

first you would write it with the other numbers it gives which should look like this: 4+(7-5) then you do the part that is in parentheses 7-5=2 then 4x4x4x4 which equals 256 then you multiply the two together and you should end up with 512

We can describe 3x - 2 as an expression.

Lesechka [4]

Given:

3x - 2

To find:

Describe the parts of the expression

Solution:

3x - 2Let us consider, f (x) = 3x - 2

The standard equation of the straight line is given by, y = mx + c

comparing the given equation with straight line equation, we get,

f (x) = y

m = 3

c = -2

m is the gradient of line

c is the y intercept (the graph crosses the y - axis)

A researcher is selecting lab rats for her experiment. She assigns each rat a number and picks numbers out of a hat while blindf

laiz [17]

Answer: $\dfrac{76}{89}$

Step-by-step explanation:

The pool of rats from which the researcher is drawing participants is composed of the following:

23 male albino rats

21 male spotted rats

35 female albino rats

11 female spotted rats

Total rats = 23+21+35+11 =90

$P(male\ albino)=\dfrac{23}{90}$

After drawing first rat , total rats remained = 89

$P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}$

The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = $\dfrac{76}{89}$

Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of 12 ft.3

Eva8 [605]

Alright, let get started.

Kyle has a storage box having dimensions 2 ft long, 3 ft high and volume 12 cubic feet.

The formula for volume is = $length * width * height$

Suppose the width is w so,

$12 = 2 * 3 * w$

$12 = 6w$

Dividing by 6 in both sides

w = 2 feet

Myla has a storage box that is 4 ft high and 2 feet long and volume 16 cubic feet.

Suppose the width is w hence

$16 = 4 * 2 * w$

$16 = 8 w$

Dividing 8 in both sides

w = 2 feet

Hence the width of Kyle and Myla's boxes, both are 2 feet. : Answer

Hope it will help :)
