Answer:

  Dimension of rectangle = 5.25 x 8.5 cm

Explanation:

   Length of rectangle = 5.25 cm

  Area of rectangle = 44.625 cm²

  Area of rectangle = Product of the sides.

  44.625 = 5.25 x Length of other side

 Length of other side = 44.625/ 5.25

                                    = 8.5 cm

 Dimension of rectangle = 5.25 x 8.5 cm

Answer:

Length of other side = 8.5 cm .

Step-by-step explanation:

Given : A rectangle has a length of 5.25 cm and area of 44.625cm squared 2.

To find:  What does the length of the rectangle have to be.

Solution: we have given that

  A length of the one side of rectangle =5.25 cm  

Area of the rectangle = 44.25 cm² .

Area of the rectangle  =length  of one side * length  of other side

plugging the value

44.25   =5.25 * length  of other side

On dividing both side by 5.25

\frac{44.625}{5.25} =\frac{ 5.25 * length  of other side }{5.25}

Length of other side = 8.5 cm .

Therefore, Length of other side = 8.5 cm .

VladimirAG [237]

Answer:

n=\frac{0.4(1-0.4)}{(\frac{0.05}{1.96})^2}=368.79  

n=369

Step-by-step explanation:

1) Notation and definitions

X=40 number of the selected labourers opt for a new incentive scheme.

n=100 random sample taken

\hat p=\frac{40}{100}=0.4 estimated proportion of the selected labourers opt for a new incentive scheme.

p true population proportion of the selected labourers opt for a new incentive scheme.

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

2) Solution tot he problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.05 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

And replacing into equation (b) the values from part a we got:

n=\frac{0.4(1-0.4)}{(\frac{0.05}{1.96})^2}=368.79  

And rounded up we have that n=369

Which of the following expressions are equivalent to −5.93+(−8.62)+5.93?
vampirchik [111]

Answer:

  • A, B, C, D

Step-by-step explanation:

  • −5.93 + (−8.62) + 5.93 =
  • −5.93 - (8.62 - 5.93) =         B
  • −(5.93 + 8.62) + 5.93 =       C
  • −5.93 −8.62 - (- 5.93) =       D
  • -8.62                                    A

yaroslaw [1]

This question is based on least common multiple method.

As given in the question,

Aunts are taking pictures in group of = 5

Uncles are taking pictures in group of = 10

So we have been asked what is the minimum number of aunts Sana have.

As we have been given that the number of aunts and uncles is equal so to find the minimum number of aunts we will apply the least common multiple method.

So we get LCM of 5,10 as 10

Hence there are minimum 10 aunts.

saul85 [17]

Answer: Annabelle is using  the a measure of central tendency defined as the Mode.

Step-by-step explanation: A measure of central tendency in its simplest definition is a single value or measure that can safely be used to represent all members belonging to an entire set of given data. Hence, as a good illustration, one figure can be used to confidently represent all other ninety nine figures where a set of one hundred figures were given.

The mean, median and mode are commonly accepted measures of central tendency.

The mode is the most frequently occurring value in a given set of data. As such, the modal value is statistically acceptable as a representative of the entire set of values or data.

If Annabelle measures the sides of 15 right triangles and based on her observations, she concludes that for any right  triangle the sum of the squares of the two legs is equal to the square of the hypotenuse, what she has done is taking the most frequently occurring value, and in her experiment, the most frequent of all observed data satisfies the Pythagorean Theorem.

That is why Annabelle can confidently make her assumption.
