Answer:
Step-by-step explanation:
In the given triangle
With reference angle A
perpendicular (P) = 3
hypotenuse (h) = 5
So sin A = p/h = 3/5
and
With reference angle C
perpendicular (p)= 4
hypotenuse (h) = 5
Sin C = p/h = 4/5
hope it helps :)
To determine the measure of the angle with the cosine value equal to 0.208, we have to use the inverse trigonometric functions. In this number, we have the arccosine which is also written below.
cos⁻¹(0.208) = 77.9948⁰
Therefore, the measure of the angle with cosine equal to 0.208 rounded to the nearest thousandth is <em>77.995⁰</em>.
When two events are dependent, this means that one event
cannot occur without the other, or simply put the two events are connected to
each other in one way or the other.
When two events are independent, this means that the two
events can occur separately, with one event having no effect on the occurrence
of the other.
Therefore the dependent and independent events are as
follows:
Independent event:
<span> c. rolling a die
twice</span>
The outcome of the first die does not affect the outcome
of the second die, hence independent.
Dependent event:
d. drawing one card from a standard deck, not replacing
it, and then selecting another card
<span>By the act of not replacing the drawn card, we are
changing the probability of selecting another card, hence dependent.</span>
Answer: 20
Step-by-step explanation:
= 1/5 (10)^2
= 1/5 * 100
= 20
To write an expression that shows 9 * 475 multiply using expanded form an distributive property we break 475 into three numbers
475 can be break into 400 + 70 + 5
Now we multiply by 9
9 x 475
9 x (400 + 70 + 5) (expanded form of 475)
We use distributive property here.
We distribute 9 inside the parenthesis
9 x 400 + 9 x 70 + 9 x 5
3600 + 630 + 45
4,275
