Answer:

$H_0:\mu\geq56\\\\ H_a:\mu$

Step-by-step explanation:

Null hypothesis $(H_0)$ : It is a statement about the population parameter that contains = , ≤ or ≥ signs.

Alternative hypothesis $(H_a)$ : It is also a statement about the population parameter but against the null hypothesis that contains = , < or > signs.

Given : The process that produces Sonora Bars (a type of candy) is intended to produce bars with a mean weight of 56 gm.

here , Population parameter = $\mu$ [ Population mean ]

i.e. $\mu$

Objective : Whether the mean is smaller than it is supposed to be.

Then, the set of hypothesis will be :

$H_0:\mu\geq56\\\\ H_a:\mu$

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 70 square feet. Find the

Vedmedyk [2.9K]

Answer:

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Step-by-step explanation:

Step(i):-

Let 'x' be the length of the rectangle

Given that the width is 3 feet shorter than the length

The width of the rectangle = x -3

Area of the rectangle = length × width

Step(ii):-

Area of the rectangle = length × width

= x ( x-3)

Given that the area of the rectangle = 70 square feet

x ( x-3) = 70

⇒ x² - 3x - 70 =0

⇒ x² - 10 x + 7 x - 70 =0

⇒ x (x -10) +7( x-10) =0

⇒ ( x+7) ( x-10) = 0

⇒ x =-7 and x=10

Final answer:-

we choose x=10

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm
