quester [9]3 years ago
5 0

Answer:

The value of f(4) is 23

Step-by-step explanation:

f(x) = x² + 7

1) Plug in x as 4.

f(4) = 4² + 7

2) Simplify 4² to 16.

f(4) = 16 + 7

3) Simplify.

23

resulting in ......

The value of f(4)is 23

Roger completed a probability experiment with a coin. He flipped the coin 32 times, and it landed on tails eight times. He looke
pav-90 [236]

1 to 3

Since you know that he landed on tails 8 out of 32 times, he must have flipped heads for the flips he did not flip tails. So, subtract 32 minus 8, which equals 24, and your answer is 8 to 24. Simplify this like you would with a fraction; the greatest common factor is 8 so divide the "numerator" and the "denominator" by 8. Therefore your final answer is 1 to 3.

Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke
In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = a person has cancer

<em>B</em> = a person carries the marker.

<u>Given:</u>

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725

Thus, the probability that a person with the marker develops cancer is 0.0725.

An apple grower finds that if she plants 40 trees per acre, each tree will yield 150 bushels of apples. She also estimates that
kozerog [31]

Answer:

41 trees per acre

Step-by-step explanation:

For each tree per acre

Yield = 150 bushels of Apple

: Each tree tree will have :

150/40 = 3.75 bushels of Apple

Now;

For an additional tree(= 41 trees)

We would normally have for an acre to be

( 150/40) × 41 = 153.75 bushels of apples

But since in this case, there is a decrease of three bushel, we have

For the 41 trees per acre to be

153.75 - 3 = 150.75

Hence,

For each tree, we would have:

150.73 / 41 = 3.677 bushels of Apple

Conclusion:

40 trees yields 150 bushels of Apple per acre

41 yields 150.75 bushels of Apple per acre
