Step-by-step explanation:
For triangle total degree=180°
2x+3x+4x=180
You get x=20°
Hence angles respective are..
40°,60°,80°
15 degrees below zero = -15
25 degrees above zero = 25
25 + 15 = 40
It rose 40 degrees.
The relationship between the number of painters and sculptors enrolled in the art school can be considered a direct variation.
<h3>Direct variation</h3>
A direct variation as implied above means, the linear relationship between the number of painters and sculptors enrolled in the art school are directly proportional.
- In essence, as the number of sculptors in the art schools increase, the number of painters increases too. This is because, more painters are needed to paint increasing work volume of the sculptors.

Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
To determine
P = ?
Using the formula

The ⋅ in the formula represents a scalar product, defined by:

The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W
Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H0: p1 - p2=0
Ha: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
