Mathematics

Dominik [7]1 year ago

The living room is rectangular. We would find the area by applying the formula for calculating the area of a rectangle which is expressed as

Area = length x width

From the information given,

internal length = 5.2

internal width = 2.95

Thus,

internal area of the living room = 5.2 x 2.95

internal area of the living room = 15.34 m^2

Hey yall, who wants a quick 20?
aliya0001 [1]

Answer:

1) 8x

2) 12x - 3y

Step-by-step explanation:

1) Both of them have a like term, so you can subtract them across

2) 10x + 2x = 12x, have a like term so you can add them across and 3y is the outlier so that stays alone.

Hope this helps!

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.
