Julli [10]

Answer:

"0.0373" seems to be the appropriate solution.

Step-by-step explanation:

The given values are:

n₁ = 43

n₂ = 35

\bar{x_1}=217800

\bar{x_2}=204700

\sigma_1=30300

\sigma_2=33800

Now,

The test statistic will be:

⇒  Z=\frac{\bar{x_1}-\bar{x_2}}\sqrt{\frac{\sigma_1^2}{n_1} +\frac{\sigma_2^2}{n_2} }

On substituting the given values in the above formula, we get

⇒      =\frac{217800-204400}{\sqrt{\frac{(30300)^2}{43} +\frac{(33800)^2}{35} } }

⇒      =\frac{217800-204400}{\sqrt{\frac{918090000}{43} +\frac{1142440000}{35} } }

⇒      =\frac{13400}{7347.93}

⇒      =1.7828

then,

P-value will be:

=  P(Z>1.7828)

=  0.0373

Find the length of segment x. If necessary, round your answer to the nearest tenth (1 decimal place).
sineoko [7]

The length of the segment x is 16.2

Step-by-step explanation:

Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.

Mathematically,

a²+b²=c²

where a=15, b=6, c=r

Hence;

15²+6²=c²

225+36=c²

√261=c

16.16

x⇒16.2
