A survey was conducted with a large group of teenagers from 6 different states and it asked them for their favourite sport out o
UkoKoshka [18]

Answer:

H0: There is no association between state and sporting preference.

H1: There is an association between state and sporting preference

Step-by-step explanation:

The hypothesis to be tested for is whether the factor 'state' is associated with the factor 'sporting preference'.

The study is therefore about 'association' and whether the distributions of sporting preferences are identical across states. In scenario in this case is the test for association which is the most appropriate test.

Two factors are deemed to not be associated unless there is supporting evidence to suggest otherwise. Since the null hypothesis is the default belief, the correct pair of hypotheses are:

H0: There is no association between state and sporting preference.

H1: There is an association between state and sporting preference

While on vacation Craig bought a pair of sunglasses for $15.98 for $7.99 5 postcards and a beach towel the beach towel cost 0.50
NISA [10]

Answer:

$0.79.

Step-by-step explanation:

Let T= The price of beach towel,

P = The cost of each postcard.

S = The cost of sunglasses.

H = The cost of hat.

We have been given that while on vacation Craig bought a pair of sunglasses for $15.98. The beach towel cost 0.50 cents more than half the price of sunglasses.

We can set this information in an equation as:

T=\frac{15.98}{2}+0.50

T=7.99+0.50  

T=8.49  

We are told that Craig gave the cashier $40 and got 3.59 change and each postcard cost the same. So we can set this information in an equation as:

T+5P+S+H=40-3.59

Let us substitute our given values.

8.49+5P+15.98+7.99=40-3.59  

Let us combine like terms.    

32.46+5P=36.41      

Let us subtract 32.46 from both sides of our equation.

32.46-32.46+5P=36.41-32.46

5P=3.95  

Let us divide both sides of our equation by 5.

\frac{5P}{5}=\frac{3.95}{5}  

P=0.79  

Therefore, each postcard costs $0.79.

two interior angles of a triangle each measure 34degrees what is the measure of the third interior angle
geniusboy [140]

Answer:

112°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°

Let x = unknown angle

⇒ 34 + 34 + x = 180

⇒ 68 + x = 180

⇒ x = 180 - 68

⇒ x = 112°
