Hey there,

So the formula of a area of a square would be 1 side x's the other side so it would be L*W*H.

Question
---------------------------------------------------------------------------------------
$12x^4(- \frac{5}{6} x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the constant: 12 x (-5/6)
---------------------------------------------------------------------------------------
$-10x^4( x^3y^2)$

---------------------------------------------------------------------------------------
Multiply the x (we add the power together when we multiply)
---------------------------------------------------------------------------------------
$-10x^7y^2$

---------------------------------------------------------------------------------------
Answer: -10x⁷y²

1A technical magazine stated that the mean retail cost of all models of a particular laptop was $600. A random sample of 10 stor

My name is Ann [436]

Answer:

Yes

Step-by-step explanation:

Given,

Population mean Z = 600

Sample mean, µ = 586.50

Size of the sample, n = 10

Standard deviation, σ = 26.77

The testing hypothesis is,

Null hypothesis = µ<600

Alternative hypothesis = µ≥600

The test statistics is the calculated value of Z,

(Z- µ)/(σ/√n)

= (600-586.50)/(26.77/√10)

= (13.5*3.1623)/26.77

= 42.691/26.77

= 1.5947

And at 5% level of significance, the table value of Z = 1.644

Here, calculated Z<Table value of Z, so we accept the null hypothesis.

So, the null hypothesis is accepted. The mean value of the laptop is less than 600.

Which relation is a function?

sergejj [24]

To determine which relation is a function, we can perform something called the vertical line test. We cover the graph in repeating vertical lines and if one vertical line connects with more than one point of the relation, the relation is not a function.

The relation in the bottom right corner is the only relation that passes the vertical line test.
