At a blind taste competition a contestant is offered 3 cups of each of the 3 samples of tea in a random arrangement of 9 marked
solmaris [256]

Answer:

\frac{5}{14}

Step-by-step explanation:

Data provided in the question:

Number of cups of tea offered = 3

Number of cups marked = 9

Number of cups tasted by each = 4

Now,

The probability that a contestant does not taste all of the samples

= contestant tastes only 2 samples of tea

= \frac{C_3^2\timesC_6^4}{C_9^4}

C₆⁴ = number of ways to choose 4 cups out of 6 cups of two samples

C₃² = number of ways to choose which 2 samples will be tasted

[ as 2 samples × 3 cups each = 6 cups ]

C₉⁴ = Number of ways to choose 4 cups out of 9

= \frac{5}{14}

Hence,

the correct answer is option (B) 5/14

Can anyone help me solve this problem?​
lions [1.4K]

Answer:

x=58, m<DCB=56°

Step-by-step explanation:

Ok the sum of those two angles should equal 180 degrees so,

2x+8+x-2=180

solve the equation

3x+6=180

3x=174

x= 58

M<DCB=x-2--> 58-2=56

The equation below represents the trend line of a scatter plot showing the hours spent studying versus science test scores.
navik [9.2K]

Answer:

On the science test  the point  ( 0 , 424 ) the intercepts is bigger

Step-by-step explanation:

The relation hours spend vs science test score is

y  =  6.5*x  + 424

And the relation hours spend vs Maths test score is

y  =  7.2*x   + 34.7

Making   x =  0  ( student does not study at all ) we get:

For science score test woul be

y  =  0  + 424

In case of maths

y  =  0  + 34.7

That mean student without studying will get better score in science.

The point  ( 0 , 424)   ( science ) represents the interception with y axis

in Maths case such point is  ( 0 . 34.7)
