Answer:

We can't find the answer unless there's the total amount of circumstances.

Step-by-step explanation:

QR= 2x-7

RS= x-61

QS= x+11

2x+7+x-61+x+11

? = 4x-43

zimovet [89]
100 meters is the exact same as 1000000 millimeters.

1 meter = 1000 millimeters. 
100 x 1000 = 1000000 millimeters.

prohojiy [21]

Answer: The value of test statistic is 0.696.

Step-by-step explanation:

Since we have given that

n_1=1399\\\\x_1=411\\\\p_1=\dfrac{x_1}{n_1}=\dfrac{411}{1399}=0.294

Similarly,

n_2=759, x_2=211\\\\p_2=\dfrac{x_2}{n_2}=\dfrac{211}{759}=0.278

At 0.01 level of significance.

Hypothesis are :

H_0:P_1=P_2=0.5\\\\H_a:P_1\neq P_2

So, the test statistic value would be

z=\dfrac{(p_1-p_2)-(P_1-P_2)}{\sqrt{\dfrac{P_1Q_1}{n_1}+\dfrac{P_2Q_2}{n_2}}}\\\\z=\dfrac{0.294-0.278}{\sqrt{0.5\times 0.5(\dfrac{1}{1399}+\dfrac{1}{759})}}\\\\z=\dfrac{0.016}{0.023}=0.696

Hence, the value of test statistic is 0.696.

“Solve for x” x/3 + x-1/4 =2+x
Lana71 [14]

Answer:

-27/5

Step-by-step explanation:

[x*4 + 3(x-1)]\12=2+x

4x+ 3x -3 =12(2+x)

7x -3 =24 +12x

7x-12x =24 +3

-5x =27

x = (-27/5)
