Answer:

False

Step-by-step explanation:

A rhombus is a quadrilateral with

1. all side length equal

2. opposite side parallel

3. opposite angles are congruent.

______________________________________

If there are two rhombus with same side length ,

conditions so that they must be always congruent.

1. Side length must be equal

2. corresponding angles to equal sides must also be equal.

It is possible that the sides of two rhombus will be same

but their angles can differ and hence the two rhombus may or may not be congruent.

Thus,

Two rhombuses with the same side lengths are always congruent

given statement is false

According to a recent survey, the population distribution of number of years of education for self-employed individuals in a c

strojnjashka [21]

Answer:

a) $n=100,\,\mu_s = 14.7, \,\sigma_s=0.32$

b) $n=400,\,\mu_s = 14.7, \,\sigma_s=0.16$

c) "a.The mean of the sampling distribution stays the same, but the standard error decreases."

Step-by-step explanation:

a) We have a population with mean of 14.7 and standard deviation of 3.2.

We have to calculate the parameters of the sampling distribution (mean and standard deviation), for a sample size of n=100.

The mean for the sampling distribution is the same of the population:

$\mu_s=\mu=14.7$

The standard deviation of the sampling distribution is related to the population standard deviation by the inverse of the square of the sample size:

$\sigma_s=\sigma/\sqrt{n}=3.2/\sqrt{100}=3.2/10=0.32$

b) For a sample size of n=400, the mean is the same (14.7), but the standard deviation becomes:

$\sigma_s=\sigma/\sqrt{n}=3.2/\sqrt{400}=3.2/20=0.16$

c) "a.The mean of the sampling distribution stays the same, but the standard error decreases."

As we calculated, the standard error decreases as the sample size increases. This is because the variability of the variable is reduced as the sample size is bigger.

The mean stays the same independently of the sample size.

What is the distance between point R (−1, 7) and point T (−7, 7) ?

zepelin [54]

You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

M is the midpoint of AB. If AM = 5x+10 & MB = 4x+16, find the value of AM

devlian [24]

Answer:

$AM =40$

Step-by-step explanation:

Given

$AM = 5x + 10$

$MB = 4x + 16$

Required

Determine AM

Since M is the midpoint, we have that;

$AM = MB$

Substitute values for AM and MB

$5x + 10 = 4x + 16$

Collect Like Terms

$5x - 4x = 16 - 10$

$x = 6$

To solve for AM; substitute 6 for x in $AM = 5x + 10$

$AM = 5 * 6 + 10$

$AM =30 + 10$

$AM =40$
