Answer:

7/10 (70%)

Step-by-step explanation:

There are papers in the bag labeled 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. There are 5 pieces of paper that are odd, which are 1, 3, 5, 7, 9. Then, you also have to add in all the numbers less than 5, which are 1, 2, 3, 4. Now, 1, and 3, are already selected so you need to add 2 and 4. This leaves you with a group of numbers, 1, 2, 3, 4, 5, 7, 9. Those are 7 numbers, out of the possible 10, which means there's a 7/10 chance. (70%) chance.

Tan^2 70° -sec^2 70°​
kipiarov [429]

Answer:

-1

Step-by-step explanation:

We need to find the value of tan² 70° -sec² 70°​.

We know that,

\sec^2\theta-\tan^2\theta=1 ...(1)

We can write the given expression as :

tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)

=-(sec² 70°-tan² 70°)

Using identity (1)

=-(1)

= -1

Hence, the value of the given expression is -1.

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .42. Find the proba
pashok25 [27]

Answer:

0.497

Step-by-step explanation:

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

From the question :

n = 6 ; x = 3 ; p = 0.42

P(x = 3) +... P(x = 6)

P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)

P(x = 3) = 20 * 0.074088 * 0.195112

P(x = 3) = 0.28910915712

Then find p(x = 4).. + p(x = 6)

Using a calculator :

P(X >= x) = 0.497
