Find two numbers x and y with a sum of 200 and a difference of 82

enyata [817]

Answer:

Let x be the bigger number, and y be the smaller number.

$x+y=200$

$x=200-y$

Since the difference is 82,

$x-y=82$

Substitute x in:

$(200-y)-y=82$

$200-2y=82$

$2y=200-82$

$2y=118$

$y=59$

$x=200-59$

$x=141$

Consider the e-billing case. The mean and the standard deviation of the sample of n = 65 payment times are xbar= 18.4730 and s =

Travka [436]

Answer: The null and the alternative hypotheses are given below:

$H_{0}:\mu=18.6$

$H_{a}:\mu$

Under null hypothesis, the test statistic is:

$z=\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

$=\frac{18.4730-18.6}{\frac{3.9045}{\sqrt{65}} }$

$=-0.26$

$\therefore z=-0.26$

Now we have to find the left tailed critical value at 0.01 significance level using the standard normal table.

The critical value is:

$z_{critical}=-2.33$

Since the test statistic is -0.26 lies in acceptance region because the critical region is beyond -2.33, therefore, we fail to reject the null hypothesis.

The three angles of a quadrilateral are 55,73,105 what is the fourth angle

Blizzard [7]

Answer:

127°

Step-by-step explanation:

In a quadrilateral, sum of four angles is 360°.

Consider the fourth angle x.

so,

55° + 73° + 105° + x = 360°

x = 360° - 233°

x = 127°
