Answer: The scale factor of dilation is 2:1

Step-by-step explanation: You can see that the sides of the blue triangle are of lenght 4 and 3, and for the red triangle, the lenghts are 8 and 6 (so the lenghts are doubled)

Here we can see that the dilation has a factor of dilation = 2 (meaning that the red triangle sides have two times the lenghts of the blue triangle sides). The factor can be written as 2:1

Give one real life example of each correlation: positive, negative, and no correlation.

mixer [17]

In a positive correlation, both variables increase together. An example of this is a company's profit's relationship with its sales. The greater the sales, the greater the profit.
A negative correlation is where one variable decreases with increase in the other. An example is the time taken to reach somewhere and the speed traveled at. The faster you move, the less the time.
No correlation means the two variables are not related. An example of this is as you get older, it does not mean you will get better grades.

A pizza parlor offers 10 toppings. How many 3-topping pizzas could they put on their menu? Assume double toppings are not allowe

andreev551 [17]

Using combination and permutation we found out that there are 30240 ways to make varieties of pizza with 3 toppings.

Given 10 toppings

10C3 =10!/3! 7! =120

10P5 =10!/5! =30240 ways

A permutation is a process of placing objects or numbers in order. Combining is the ability to select an object or number from a group of objects or collections such that the order of the objects does not matter.

In mathematics, a combination is the selection of elements from a set with different members, so the order of selection does not matter.

The process or state of binding. Some combination: A combination of ideas. Combined: A chord is a combination of notes. Alliance of Individuals or Parties: Combinations to restrict transactions.

Marcus bought pumpkins that weigh 8 lb, 11 lb, 23 lb, and 15 lb. What is the mean weight of his pumpkins? Round to the nearest t

OverLord2011 [107]

In this question, it is given that

Marcus bought pumpkins that weigh 8 lb, 11 lb, 23 lb, and 15 lb.

And we have to find the mean weight .

To find the mean weight, we will first add all the weights, then divide them by number of pumpkins which is 4.

So the mean weight is

$Mean \ weight = \frac{8+11+23 +15}{4} = \frac{57}{4} = 14.25 lb$

Therefore the mean weight is 14.25 lb .

A study involves a population of 400 tall women. This population has a mean height of 179.832 cm and a standard deviation of 12.

Fofino [41]

Answer: 0.0386

Step-by-step explanation:

Given: The population of 400 tall women has a mean height $(\mu)$ of 179.832 cm and a standard deviation $(\sigma)$ of 12.192 cm.

Let X be a random variable that represents the height of woman.

Sample size : n= 50

The probability that the mean for this sample group is above 182.88 will be :

$P(\overline{X}>182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z>1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z$

Hence, Required probability = 0.0386
