Can you construct a triangle that has side lengths 2 yd, 9 yd, and 10 yd?
yan [13]

Yes


The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.


This happens for all possible couples in your case:


2+9=11>10


2+10=12>9


9+10=19>2

I am totally confused trying to help my son, on this problem
sladkih [1.3K]

Answer: x=4

Step-by-step explanation: You have to distribute the negative signs

x - (4x-7)= 5x-(x+21)

x - 4x + 7 = 5x - x - 21

- 3x + 7 = 4x - 21

28 = 7x

X = 4

ppose we are testing a new shampoo to see if it makes hair grow faster. We knowthat the average rate of hair growth is 0.5 inche
alukav5142 [94]

Answer:

Type II error occurred

Step-by-step explanation:

It is given that a new shampoo is being tested to determine whether the hair grows faster by using this shampoo.

It is known that hair grow at 0.5 inches per month at average.

The hypothesis are,

Null hypothesis, $H_0: \mu=0.5$

Alternate hypothesis, $H_1: \mu>0.5$

But it is known that :

Type $I$ error occurs when rejecting the null hypothesis when the null hypothesis is true actually.

Type $II$ error occurs \text{when we fail reject the null hypothesis} when the null hypothesis is actually false.

Now here since the null hypothesis is not been rejected, type  $II$ error had occurred.
