WHAT IS X^2+3X-10=0 IN SIMPLEST RADICAL FORM

1 answer:

7 0

      x² + 3x - 10 = 0
          x = -(3) ± √((3)² - 4(1)(-10))
      2(1)
      x = -3 ± √(9 + 40)
   2
      x = -3 ± √(49)
   2
      x = -3 ± 7
      2
      x = -3 + 7 U x = -3 - 7
      2    2
      x = 4 U x = -10
      2    2
      x = 2 U x = -5

Solution Set: {2, -5}

A 6 sided number cube is tossed. what is the probability of rolling a 6 or an odd number?

Veronika [31]

For any probability the formula is $P_{desired}=\frac{desired}{total}$ . In this case we have 4 desired outcomes (the odds, 1, 3 and 5, and also 6) out of 6 total sides, so our probability $P_{oddor6} =\frac{odd or 6}{total sides}=\frac{4}{6} = \frac{2}{3}$ .

Mutually exclusive means the events cant occur at the same time. In our case it is not possible to roll both a 6 and an odd number at the same time since 6 is even. Therefore the events ARE mutually exclusive.

Combine the two parts and C is the correct answer. <span />

The perimeter of a rectangle table is 680 cm if the length of the table is 24 cm more than the race the width of the table find

postnew [5]

Answer:

Length is 182 cm and width is 158 cm.

Step-by-step explanation:

Given:

Perimeter of rectangle table = 680 cm.

Let the width of the table be $x$ .

Now according to given length of the table is 24 cm more than the race the width

hence length = $24+x$ .

But perimeter of rectangle = 2(length+width)

Substituting the values we get;

$2(24+x+x)=680\\24+2x=\frac{680}{2}\\\\24+2x=340\\2x=340-24\\2x=316\\\\x= \frac{316}{2}=158 \ cm$

Hence width = 158 cm

Now, length = 24 cm + width = 24 cm + 158 cm = 182 cm

Hence the dimension of table are 182 cm and 158 cm.

If the central limit theorem is applicable, this means that the sampling distribution of a ___________ population can be treated

3241004551 [841]

The answers are Sample population and the Sample Size is Large Enough.

<h3>What are population and sample?</h3>

It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.

If the central Limit Theorem is applicable, this means that the sampling distribution of a sample population can be treated as normal since the sample size is large enough.

Also, It asserts that the distribution of the average of the sum of many identically distributed and independent variables will be approximately normal, irrespective of the statistical properties.

Thus, the answers are Sample population and the Sample Size is Large Enough.
