Answer:

sin x + cos x = 5/13 + 12/13

Step-by-step explanation:

Given that tan x = 5/12, what is the value of sin x + cos x?

draw a triangle with opposite leg=3 and hypotenuse=5

tan p = opposite/adjacent = 3/4

similarly, in a 5-12-13 right triangle

sin x + cos x = 5/13 + 12/13

Probability is the likelihood or chance that an event will occur. The complement of the probability will be 0.95

Probability is the likelihood or chance that an event will occur. Mathematically:

Probability = expected outcome/total outcome

Given that the probability of an event is P(A) = 0.05, the complement will be expressed as:

P'(A) = 1 - P(A)
P'(A) = 1 - 0.05
P' (A) = 0.95

Hence the complement of the probability will be 0.95

Step-by-step explanation:

(3/5)^3= 27/125

So a is the correct answer

Answer:

Answer option D.

If we simplify the expression (3/5)^3 we can see that ^3 means you cube both the numerator and the denominator since 3/5 is in parenthesis.

Numerator:

3 cubed(3^3) would result in

= 9

Denominator:

5 cubed(5^3) would result in

= 125

Hence, you'll get 9/125.

Answer:

1.95 x 10^5

Step-by-step explanation:

First look at the 4th digit in the number 194720 as the the question said to round to 3 significant figures. If the 4th digit is more than 5, then add 1 to the third digit which results in 195000. Now the question also said to express in standard form. Look for the first non-digit number in 195000. After 1 put a decimal point and remove all the zeros after the point which results in 1.95. Now count how many digits you moved to the left which comes as 5. Write the answer as 1.95 x 10^5.

Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.

Answer:

n < 0

Step-by-step explanation:

Given that:

A number less than 0

Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.

From the following answer chioce:

[A] n=0

[B] n greater than n 0

[C] n greater then n with a underscore on the bottom 0

[D] n greater than 0 with a underscore 0​

We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.

I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.

< → less than

> → greater than

A number less than 0 ⇒ n < 0
