A company has developed a new ink-jet cartridge for its printer that it believes has a longer life-time on average than the one

Mila [183]

Answer:

The test hypothesis is :

$H_0: \mu=1502.5\\ H_a: \mu>1502.5$

Step-by-step explanation:

Consider the provided information.

Null hypothesis refer the population parameter is equal to the claimed value.

If there is no statistical significance in the test then it is know as the null which is denoted by $H_0$ , otherwise it is known as alternative hypothesis which denoted by $H_a$ .

The historical average lifetime for cartridges produced by the current process is 1502.5 pages.

Hence, the test hypothesis is :

$H_0: \mu=1502.5\\ H_a: \mu>1502.5$

A 12 foot ladder is leaning up against the side of a house the ladder makes an angle of 62° with the ground. How far up the side

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

The ladder forms a right angle triangle with the house and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height, h from the top of the ladder to the base of the house represents the opposite side of the right angle triangle.

The distance from the bottom of the ladder to the base of the house represents the adjacent side of the right angle triangle.

To determine the height, h that the ladder reaches, we would apply

the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin 62 = h/12

h = 12Sin62

h = 12 × 0.8829

h = 10.6 feet

Y= 70° because the values in a triangle must equal 180 so,

60+50= 110
180-110= 70

and since x in this equation is the same as y, by default,

x= 70°
