There are 76,000 acres of state Parkland in Georgia this is 4000 acres more than three times the number of acres of state Parkla
pashok25 [27]

Answer:

There are 240,000 acres of the state parkland in Mississippi.

Step-by-step explanation:

Let a= Mississippi's parkland acres

You can use either Distributive Property, or The Order of Operations.

Distributive Property:

(76,000+4,000) 3= a

228,000+12,000= a

240,000= a

Order of Operations:

(76,000+4,000) 3= a

(80,000) 3= a

240,000= a

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.
