Step-by-step explanation:

let eqn be y = mx + b.

m = (5 - (-11))/(0 - 4) = -4

sub (0, 5):

5 = -4(0) + b

b = 5

therefore, eqn is y = -4x + 5

Answer:

≈ 4,22 m

Step-by-step explanation:

volume = 20000L = 20000 dm^3 = 20 m^3

diameter = 2,4m

the volume of a cilinder is π * r^2 * h (height)

20 = π * 1,2^2 * h

h = $\frac{20}{\pi * 1,44} \\$ ≈ 4,42 m

Calculate the perimeter and area of this shape.<br> Perimeter =

konstantin123 [22]

<h3><u>Answer</u><u>:</u></h3>

Perimeter → 25cm

Area → 25.5cm²

<h3><u>Explanation</u>:</h3>

$perimeter = > 2.5 \times 2 + 5.5 + 3.5 + 6 + 3 + 2 = 5 + 9 + 9 + 2 = 25$

$area = > 3 \times \frac{1}{2} \times 2 + 3 \times 3.5 + 6 \times 2 = 3 + 12 + 10.5 = 25.5$

Answer:

32.5 ft

Step-by-step explanation:

The length of the side opposite the given angle is found using the sine relation:

Sin = Opposite/Hypotenuse

height on building = (33 ft)·sin(80°) ≈ 32.5 ft

The ladder reaches about 32.5 feet up the side of the building.

A 37 bag sample had a mean of 421 grams. Assume the population standard deviation is known to be 29. A level of significance of

Ierofanga [76]

Answer: $H_0:\mu=421$

$H_a : \mu\neq421$

Step-by-step explanation:

A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.

Given: A 37 bag sample had a mean of 421 grams.

Let $\mu$ be the population mean.

Then, the null hypothesis would be:

$H_0:\mu=421$

whereas the alternative hypothesis would be:

$H_a : \mu\neq421$
