What is the abscissa of the midpoint of the line segment whose endpoints are (5√2,2√3) and (√2,2√3)

xxMikexx [17]

Let
A------> (5√2,2√3)
B------> (√2,2√3)

we know that
the abscissa and the ordinate are respectively the first and second coordinate of a point in a coordinate system
the abscissa is the coordinate x

step 1
find the midpoint
ABx------> midpoint AB in the coordinate x
ABy------> midpoint AB in the coordinate y

ABx=[5√2+√2]/2------> 6√2/2-----> 3√2
ABy=[2√3+2√3]/2------> 4√3/2-----> 2√3

the midpoint AB is (3√2,2√3)

the answer is
the abscissa of the midpoint of the line segment is 3√2

see the attached figure

A car service chain hopes to increase productivity and has set a goal of an average of at least 25 customers served per day acro

Korolek [52]

Answer:

Step-by-step explanation:

Given that:

population mean = 25

sample size = 50

sample mean = 24.02

standard deviation = 4.75

The null and alternative hypothesis can be computed as follows:

Null hypothesis:

$\mathbf{H_o : \mu \geq 25}$

Alternative hypothesis:

$\mathbf{H_1 : \mu < 25}$

b. Yes, the necessary assumptions to perform the inference are satisfied because the sample size is large and as a result, the data approximately follows a normal distribution.

c. To determine the P-value, we need to Find the t-test statistics which can be expressed by the formula:

$t = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t = \dfrac{24.02 -25}{\dfrac{4.75}{\sqrt{50}}}$

$t = \dfrac{-0.98}{\dfrac{4.75}{7.07}}$

t = - 1.458

The degree of freedom df = n- 1 = 50 - 1 = 49

The p -value = P(T < -1.458)

p -value = 0.0756

d. The p-value is the probability of finding the observed value when null hypothesis is true.

Decision rule: To reject the null hypothesis if the level of significance at 0.05 is greater than the p-value.

Conclusion: We fail to reject the null hypothesis because the p-value is greater than the level of significance, hence, there is no sufficient evidence to conclude that the company has failed to meet its goal.

Can someone tell me where to graph this

iren [92.7K]

Answer:

(7, -6)

Step-by-step explanation:

You will graph it at this point because the point is basically the origin and when you rotate it clockwise 90° it will end up in Quadrant IV.
