The value of x is 1 if the angle CBA is 43x, and after applying the tangent-chord angle theorem option (B) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle shown in the picture.
From the tangent-chord angle theorem:
Angle CBA = (1/2)[360 - (272x+2)]
Angle CBA = (1/2)[360 - 272x - 2]
Angle CBA = (1/2)[358 - 272x ]
43x = 179 - 136x
179x = 179
x = 1
Thus, the value of x is 1 if the angle CBA is 43x, and after applying the tangent-chord angle theorem option (B) is correct.

A medical test has a 95% accuracy of detecting a Condition Z if the person has it. It also has a 97% chance to indicate that the person does not have the condition if they really don't have it. If the incidence rate of this disease is 10 out of every 100: What is the probability that a person chosen at random will both test positive and actually have the disease (i.e., get a true positive)
Answer:
0.77
Step-by-step explanation:
According to the Question,
Let, We have 10000 patients & If the incidence rate is 10 out of 100, then 1000 people will have the disease.
Given, A medical test has a 95% accuracy of detecting Condition Z if the person has it. Thus, Out of those 1000, 950 will test positive.And, It also has a 97% chance to indicate that the person does not have the condition if they really don't have itSo, Out of the 9000 people who don't have the disease, 3%
that is, 270 People, will get a false positive.
Thus, the probability that a person is chosen at random will both test positive and actually have the disease is [tex]\frac{950}{950+270}[/tex] .
[tex]\frac{950}{1220}[/tex] ⇒ 0.7786 ≈ 0.77Out of the people who have already taken their seats at a seminar, 2 people have black hair while 2 people do not. Considering this data, how many of the next 16 people to take their seats should you expect to be black-haired?
Answer:8
Step-by-step explanation:
We can expect 8 of the next 16 people to have black hair, based on the given information.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Since 2 out of the total number of people who have already taken their seats at the seminar have black hair
we can assume that the probability of a person having black hair is 2 out of the total number of people who have taken their seats.
The probability of a person having black hair can be expressed as:
P(black hair) = 2/(2+2) = 1/2
This means that out of the total number of people who have already taken their seats, half of them have black hair.
If we assume that the next 16 people to take their seats are chosen randomly and independently from the population,
we can use the expected value formula to calculate the number of people with black hair we would expect among those 16 people:
Expected value = total number of people x probability of having black hair
Expected value = 16 x (1/2)
Expected value = 8
Therefore, we can expect 8 of the next 16 people to have black hair, based on the given information.

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the 8 expressions are not given.
The general explanation is as follows
As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.
Then you categorize each result, depending on if it equals [tex]5^{10}[/tex] or not
Take for instance:
[tex]5^5 * 5^5[/tex]
Using law of indices:
[tex]5^5 * 5^5 = 5^{5+5[/tex]
[tex]5^5 * 5^5 = 5^{10[/tex] ---- equivalent
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}}[/tex]
Factorize the numerator
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}[/tex]
Cancel out 2
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}[/tex]
Apply law of indices
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10[/tex] ---equivalent
[tex]125 * 78125[/tex]
Express as exponent
[tex]125 * 78125 = 5^3 * 5^7[/tex]
Apply law of indices
[tex]125 * 78125 = 5^{3+7[/tex]
[tex]125 * 78125 = 5^{10[/tex] ---- equivalent
[tex]5^3 + 5^7[/tex]
Solve exponents
[tex]5^3 + 5^7 = 125 + 78125[/tex]
[tex]5^3 + 5^7 = 78250[/tex] ---- not equivalent
An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded.
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply: *
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.

x=4
Step-by-step explanation:
Multiply the exponents
(2x-4)^12=(4^2)^6 (exponents multiply so)
(2x-4)^12=4^12
4^12 = 16777216
(2x-4)^12= 16777216
Take the 1/12 exponent for both sides
that will remove the ^12 exponent from the left side and will take the 12th root for the right.
2x-4=4
add 4 to both sides
2x=8
divide both sides by 2

Have a nice day!!
Answer:
[tex]p = \frac{2 - 3g}{(g + 4)} [/tex]
Step-by-step explanation:
[tex]g = \frac{2 - 4p}{3 + p} \\ g(3 + p) = 2 - 4p \\ 3g + pg = 2 - 4p \\ pg + 4p = 2 - 3g \\ p(g + 4) = 2 - 3g \\ \frac{p(g + 4)}{(g + 4)} = \frac{2 - 3g}{(g + 4)} \\ p = \frac{2 - 3g}{(g + 4)} [/tex]
Ed has a recipe that uses [tex]\frac{2}{3}[/tex] cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? Answer in a fraction pls! Will give brainliest!
Answer:
The formula for this would be [tex]2/3 \times4[/tex]
Since we need to multiply the fraction against the amount of batches, to get the final result of cups of flours. (It only makes sense!)
8/3 is the correct answer
2 2/3 is the mixed fraction
Answer as an improper fraction: 8/3
This converts to the mixed number 2 & 2/3
So he'll need 2 whole cups plus another 2/3 of a cup.
===========================================================
Explanation:
1 batch uses 2/3 of a cup
4 batches uses 4*(2/3) = (4/1)*(2/3) = (4*2)/(1*3) = 8/3 of a cup
Simply multiply 2/3 by 4 to get 8/3.
-----------
If you need to convert to a mixed number, then you could follow these steps
8/3 = (6+2)/3
8/3 = 6/3 + 2/3
8/3 = 2 + 2/3
8/3 = 2 & 2/3
Or you could note that 8/3 = 2.667 approximately. The decimal portion 0.667 converts to the fraction 2/3.
A population of bacteria can be modeled by the function f(t) = 1000(0,98)", where t represents
the time since the population started decaying, and f (t) represents the population of the
remaining bacteria at time t. What is the rate of decay for this population?
Answer:
Decay rate of 2%
Step-by-step explanation:
Since there is no information about the units for time, merely stating that the decay rate is 2% will suffice. The decay rate for when r < 1 is found by finding 1-r, so the rate of decay is .02, or 2%.
