This can be solved by using a standard normal distribution table. The z-score for 34 pounds is 1, the reason being that 34 is one standard deviation above the mean of 28 pounds.
Can use the table to find the cumulative probability for z = 1.00 and post the result? If you do this we can do the next simple steps.

Answer:

Area: 28 square ft

Perimeter: 22 ft

Step-by-step explanation:

To find the area:

A=Lw

A is area, L is length, w is width

A=4*7

A=28

The area is 28 <em>square</em> feet

To find the perimeter:

P=2L+2w

P=2(7)+2(4)

P=14+8

P=22

The perimeter is 22 feet.

Hope this helps!

Please help me with it is for homework<br><br> I really need help please help me

Answer:

See explanation

Step-by-step explanation:

Given two expressions:

2(s+0.5)+2(s+1.5)

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4

a. When s=0,

then

2(s+0.5)+2(s+1.5)=2(0+0.5)+2(0+1.5)=1+3=4

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 0+\dfrac{1}{4}\cdot 0\right)+4=4

b. When s=12,

then

2(s+0.5)+2(s+1.5)=2(12+0.5)+2(12+1.5)=2\cdot 12.5+2\cdot 13.5=25+27=52

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 12+\dfrac{1}{4}\cdot 12\right)+4=4(6+3)+4=4\cdot 9+4=36+6=40

c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
