2x + y = -4<br> 2x + 3y = 4
kirill115 [55]

Answer: x=4 ; y=<u> -4</u>

                            3

Step-by-step explanation:

2x + y = -4 .(-3)

2x + 3y = 4

-6x-3y=12

<u>2x + 3y = 4</u>

4x=16

x= <u>16</u>

    4

x=4

2x + 3y = 4

2.4+3y=4

8+3y=4

3y= -8+4

y=<u> -4</u>

Data is collected to perform the following the hypothesis test:
nekit [7.7K]

Answer:

option f is right

Step-by-step explanation:

Given that data is collected to perform the following hypothesis test.

H_0: \mu = 5.5\\H_a: \mu >5.5

(right tailed test)

Sample mean = 5.4

p value = 0.1034

when p value = 0.1034 we normally accept null hypothesis.  i.e chances of null hypothesis true is  the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct

f) If the mean µ does not differ significantly from 5.5 (that is, if the null hypothesis is true), then the probability of obtaining a sample mean y as far or farther from 5.5 than 5.4 is .1034.

Natalija [7]

Answer: 18 units long

Step-by-step explanation:

In the diagram, it looks like line segment AW is 6 units long and WB is 12 units long. Because of parts-whole postulate (the whole is equal to the sum of its parts), you can add AW and WB's lengths together. 6 + 12 = 18, so the length of line segment AB is 18 units long.

A Ferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. If the Ferris wheel makes one comp
Volgvan

Answer:1+10(1-\cos (\frac{\pi t}{9}))

Step-by-step explanation:

Given

radius of wheel r=10 m

Time period of Wheel T=18 s

and T\cdot \omega =2\pi , where \omega =angular velocity of wheel

\omega =\frac{2\pi }{18}

Let at any angle \thetawith vertical position of a point is given by

x=r\sin \theta

y=y_0+r(1-\cos \theta )

and \theta =\omega \times t

for velocity differentiate x and y to get

v_x=r\cos \theta =r\cos (\omega t)

v_y=0+r(\sin \theta )=r\sin (\omeag t)

Height at any time t is given by

h=1+10(1-\cos \theta )=1+10(1-\cos (\frac{\pi t}{9}))
