Answers

Answer 1
Answer:

Answer:

2 because of the way the question is written

2/5 if you get 2 wrong.

Step-by-step explanation:

1/2 * 4/5  of means multiply

numerator:  1*4 = 4

denominator = 2 * 5 = 10

Answer: 4 / 10 but this will reduce. Divide Top and Bottom by 2

4/2 = 2

10/2 = 5

Answer: 2/5

The way you should answer is 2 because the question gives you the fact that it is in 5ths. If you get it wrong then put in 2/5.

The equation cosx=(sqrt 3)/2 is an identity true or false

Answers

false, because cos(x) has no definite answer, and equations aren't identities
No. It is not an identity 'cause it involves trigonometric function and it's true for only single value (i.e.,30). You can also calculate the angle as follows:

Cos x = √3/2
x = cos⁻¹ √3/2
x = 30

In short, Your Answer would be "False"

Step-by-step explanation:

Step 1: Define

g/2 + 3

g = 8

Step 2: Evaluate

  1. Substitute in g:                                                                                               8/2 + 3
  2. Divide:                                                                                                             4 + 3
  3. Add:                                                                                                                 7

Answer:

if g is equals to 8 therefore g/2 +3 will be expressed as 8/2 +3= whuch is equals to 4

Kimberly is a program director for the channel KID. She tracked the cartoons shown on the channel for a week. The probability that the show had animals in it was 0.7. The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?

Answers

Options

  • 0.7+0.2−0.4=0.5
  • 0.7+0.2=0.9
  • 0.7+0.4=1.1
  • 0.4+0.2=0.6
  • 0.7+0.4−0.2=0.9

Answer:

(E)0.7+0.4-0.2=0.9

Step-by-step explanation:

In probability theory

P$(A or B)=P(A)+P(B)$-$P(A and B)

Let the event that the show had animals in it = A

P(A)=0.7

Let the event that the show aired more than 10 times =B

P(B)=0.4

P(A and B)= 0.2

P$(A or B)$=0.7+0.4-0.2=0.9

Therefore, the equation which  shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times is:

0.7+0.4-0.2=0.9

The correct option is E.
