Mathematics
1 answer:
love history [14]3 years ago

Answer:

θ ≈ 15°

Step-by-step explanation:

Using the sine rule in the triangle

note 7.56 × 10² = 756 and 2.4 × 10³ = 2400 , then

\frac{756}{sin0} = \frac{2400}{sin125} ( cross- multiply )

2400 × sinθ = 756 × sin125° ( divide both sides by 2400 )

sinθ = \frac{756sin125}{2400} , then

θ = sin^{-1} ( \frac{756sin125}{2400} ) ≈ 15° ( to the nearest degree )

Somebody help pls:)))

Answer: 5.4

--------------------------------------

Explanation:

Angle D = 43 is the given reference angle
side FE = 5 is the side opposite the reference angle (since its the leg furthest away from angle D)

We want to find side DE which is the other leg. This is the adjacent side with angle D as the reference angle

Use the tangent rule

tan(angle) = opposite/adjacent
tan(D) = FE/DE
tan(43) = 5/DE
DE*tan(43) = 5
DE = 5/tan(43)
DE = 5.36184355 <<-- use a calculator here; this is approximate
DE = 5.4 <<-- round to the nearest tenth

That's why 5.4 is the answer

PLEASE HURRY!!! What is the slope of the line that passes through (4, 5) and (8, -1)
Nitella [24]

Answer:

-1.5

Step-by-step explanation:

The slope of a line is given by the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let's let (4,5) be x₁ and y₁ and let's let (8,-1) be x₂ and y₂. So:

m=\frac{-1-5}{8-4}

Subtract:

m=\frac{-6}{4}

Reduce:

m=-\frac{3}{2}=-1.5

So, our slope is -3/2 or -1.5.

And we're done!

Lerok [7]

Answer:

Following are the responses to the given choice:

Step-by-step explanation:

For point a:

H_0: \mu_1 - \mu_2 = 0\\\\ H_1: \mu_1 - \mu_2 < 0

For point b:

t = -2.953

For point c:

\to  p- value = 0.0021

For point d:

Reject H_o. It could deduce that the pay of higher banking is considerably lower than the pay of higher project management.
