Answer:
1 represents the number of years passed.
step -by-step explanation:
The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346 (1/2)x and f(1) = 173
Here 1 represents the number of years that passed.
So 1 represents the number of years.
Hope this will helpful.
Thank you.
The cost of spices in US dollars is $5.45
The cost of spices in Indian rupees = 401.39 rupees
The exchange rate is
1 dollar:73.6500 rupees
So we have to exchange the Indian rupees to the US dollars
The cost of spices in Indian rupees = 401.39 rupees
The cost of spices in US dollars = The cost of spices in Indian rupees / 73.6500
Substitute the values in the equation and fins the cost of spices in US dollars
The cost of spices in US dollars = 401.39 / 73.6500
Divide the numbers
= $5.45
Hence, the cost of spices in US dollars is $5.45

The label could be written in the area marked X as "Uses a convex eyepiece lens". Then the correct option is D.
<h3>What are Sets?</h3>
Sets are the collection of well-defined elements. A set is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.
<h3>What is the Venn diagram?</h3>
It is the representation of the sets by the diagram. And shows the condition that is generated between them by the overlapping of the circle.
Shanti began to draw a Venn diagram comparing refracting and reflecting telescopes. The two overlapping circles.
The left circle is labeled Refracting telescopes.
The right circle is labeled Reflecting Telescopes.
An X in the overlap. Both as a label below and outside the overlap.
From the figure, we can say that the label could be written in the area marked X as "Uses a convex eyepiece lens".
Then the correct option is D.

Answer:
P (X ≤ 4)
Step-by-step explanation:
The binomial probability formula can be used to find the probability of a binomial experiment for a specific number of successes. It <em>does not</em> find the probability for a <em>range</em> of successes, as in this case.
The <em>range</em> "x≤4" means x = 0 <em>or</em> x = 1 <em>or </em>x = 2 <em>or</em> x = 3 <em>or</em> x = 4, so there are five different probability calculations to do.
To to find the total probability, we use the addition rule that states that the probabilities of different events can be added to find the probability for the entire set of events only if the events are <em>Mutually Exclusive</em>. The outcomes of a binomial experiment are mutually exclusive for any value of x between zero and n, as long as n and p don't change, so we're allowed to add the five calculated probabilities together to find the total probability.
The probability that x ≤ 4 can be written as P (X ≤ 4) or as P (X = 0 or X = 1 or X = 2 or X = 3 or X = 4) which means (because of the addition rule) that P(x ≤ 4) = P(x = 0) + P(x = 1) + P (x = 2) + P (x = 3) + P (x = 4)
Therefore, the probability of x<4 successes is P (X ≤ 4)
