It's less than 1 because 5/11 plus 4/11 equals 9/11 which is less than a whole

MArishka [77]

Answer:

3.06

Step-by-step explanation:

The correct answer is - 3.06

Reason -

For sample A :

mean, \bar{x_{1} } = 8.05          

Standard deviation, \sigma_{1} = 1.36          

Size, n_{1} = 50          

                 

For sample B :

mean, \bar{x_{2} } = 7.26          

Standard deviation, \sigma_{2} = 1.06          

Size, n_{2} = 38

Now,

\bar{x_{1} } - \bar{x_{2} }  = 8.05 - 7.26 = 0.79

Standard deviation error, SE = √(\sigma_{1}²/n_{1} + \sigma_{2}²/n_{2})  = 0.2580

Now,

Z-statistic = (\bar{x_{1} } - \bar{x_{2} } )/ SE

                = 0.79/0.2580

                = 3.06

⇒Z-statistic = 3.06

a store had a sale on art supplies. the price p of each item was marked down 60%. which expression represents the new price
andrezito [222]
If the price of the item drops by 60% then that means the new price is 40% of the original

new price = p*0.4

ex: 
new price = $100*0.4= $40
new price= $75*0.4 = $30

Need help with working perimeter and area please
SVETLANKA909090 [29]

Answer:

Area = 228 m²

Perimeter = 60 m

Step-by-step explanation:

The figure given shows a rectangle that has a cut triangular portion.

✔️Area of the figure = area of rectangle - area of the triangular cut portion

= L*W + ½*bh

Where,

L = 20 m

W = 12 m

b = 20 - (8 + 8) = 4 m

h = 6 m

Plug in the values

Area = 20*12 - ½*4*6

Area = 240 - 12

Area = 228 m²

✔️Perimeter = perimeter of rectangle - base of the triangular cut portion

= 2(L + W) - b

L = 20 m

W = 12 m

b = b = 20 - (8 + 8) = 4 m

Plug in the values

Perimeter = 2(20 + 12) - 4

= 2(32) - 4

= 64 - 4

Perimeter = 60 m
