Answer: There are 58 players to raise $100 to meet their goal.

Step-by-step explanation:

Since we have given that

Amount to raise = $7000

Amount given the team by the donor = $1250

Amount each player is able to raise = $100

Let the number of player be 'x'.

According to question, we get that

[tex]1250+100x\geq 7000[/tex]

So, the required number of players would be :

[tex]100x\geq 7000-1250\\\\100x\geq 5750\\\\x\geq \dfrac{5750}{100}\\\\x\geq 57.5[/tex]

Hence, there are 58 players to raise $100 to meet their goal.

Final answer:

The probability of rolling a number less than 2 on a 1-6 number cube is 0.17.

Explanation:

Probability Calculation:

There are 6 possible outcomes when rolling a number cube (1-6).

Only 1 outcome is less than 2 (rolling a 1).

Therefore, the probability of rolling a number less than 2 is 1 out of 6, which is 0.17.

For a normal distribution with a mean of 279 and a standard deviation of 3, 50% of the scores are below 282, given that 282 is one standard deviation above the mean.

In a normal distribution, 68.2% of values fall within one standard deviation of the mean,

95.4% fall within two standard deviations, and 99.7% fall within three standard deviations. Given that the bowling scores have a mean of 279 and a standard deviation of 3, a score of 282 will fall one standard deviation above the mean.

Since 68.2% of scores fall within one standard deviation around the mean, half the scores will fall below the mean and the other half will fall above it. Thus, 50% of the scores will fall below 282. In case of a normal distribution that has no skew, the mean, median, and mode are equal, which implies that half the values fall below the mean and half the values fall above it.

Final answer:

The total distance the post is driven into the ground after 6 hits of the pile driver, each hit driving the post 9 ft, is 54 ft.

Explanation:

The problem given can be solved using the concept of arithmetic sequences since each hit of the pile driver drives the post the same distance as the previous hit.

Assuming that the first hit drives the post 9 ft into the ground. Each subsequent hit will also drive it 9 ft further. To find the total distance after 6 hits, we simply multiply the distance per hit by the number of hits:

Total Distance Driven = Distance per Hit × Number of Hits

Total Distance Driven = 9 ft × 6 = 54 ft.

The total distance the post has been driven into the ground after 6 hits is therefore 54 feet.

But, with the negative sign, the answer is x= 5i (where i is imaginary)

Final answer:

The width of the arch at floor level is found by determining the points where the parabola intersects the x-axis, which are at x = 5 and x = -5. The width is the distance between these points, which is 10 feet.

Explanation:

To find the width of the arch at floor level, we need to determine the distance between the two points where the parabola represented by the equation y = -1/3(x-5)(x+5) intersects the x-axis. The x-axis represents the floor, and the points of intersection occur where y is equal to 0.

Setting the equation to 0 gives:

0 = -1/3(x-5)(x+5)

By solving for x, we get x = 5 and x = -5, which are the points where the parabola intersects the x-axis. The distance between -5 and 5 on the x-axis is 10 feet, so the width of the arch at floor level is 10 feet.

Answer:

A) P(F) = 0.124

B) P(S|F) = 0.8065

C) P(V|F^(c)) = 0.886

Step-by-step explanation:

Let us denote as follows;

F = Message contains word free

S = message is spam

V = message is valid

From the question, we are given that;

The probability that word free occurs in spam messages;P(F|S) = 50% = 0.5

The probability of the valid messages that contain free; P(F|V) = 3% = 0.03

Spam messages; P(S) = 20% = 0.2

Valid messages; P(V) = 1 - 0.2 = 0.8

A) From rule of total probability ;

probability that the message contains the word free is given as;

P(F) = P(F|S)•P(S) + P(F|V)•P(V)

P(F) = (0.5 x 0.2) + (0.03 x 0.8)

P(F) = 0.124

B) From Baye's theorem;

probability that the message is spam given that it contains free is given as;

P(S|F) = P(F|S)•P(S)/P(F)

P(S|F) = (0.5 x 0.2)/0.124

P(S|F) = 0.8065

C) From combination of complement rule and Baye's theorem;

probability that the message is valid given that it does not contain free is given as;

P(V|F^(c)) = P(F^(c)|V)•P(V)/P(F^(c))

Thus,

P(V|F^(c)) = [(1 - P(F|V))•P(V)]/(1 - P(F))

P(V|F^(c)) = ((1 - 0.03)•0.8)/(1 - 0.124)

P(V|F^(c)) = 0.776/0.876

P(V|F^(c)) = 0.886

Answer:A=253.5

Step-by-step explanation:

In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

Answer:

253.5

Step-by-step explanation:

if the side lengths of the cube is 6.5 then the surface area of one side is 42.25. Since the 6 sides of the cube are all the same you can multiply this by 6 to get 253.5

=$48

Step-by-step explanation:

Add them all up.

s + 2(s+3) + 4s-5 = 148

s + 2s + 6 + 4s - 5 = 148

Group all s together and all numbers together 7s + 1 = 148

7s = 147

Divide by 7

s = 21

Plug s=21 back in for Petro

To find the amount of money in Pertro's account, use the equation x = 148 - (y + z), where y and z represent the amounts in the other two accounts.

The equation to find the amount of money in Pertro's account can be written as:

x + y + z = 148

where x, y, and z represent the amounts in different accounts. To find the amount in Pertro's account, we need to set up another equation using the information given. If we know that the total of all accounts is $148 and we want to find the amount in Pertro's account (x), we can write:

x = 148 - (y + z)

where y and z represent the amounts in the other two accounts.

Divide the number of jelly beans (96) by the denominator (3) to find out how many jelly beans would be 1/3. This is 32. To find out how many are 2/3 you would multiply the 1/3 (32) by 2 to find that it is 64.

To find (fg)(x), multiply f(x) and g(x) by substituting g(x) into f(x) and simplifying the expression.

Explanation:

To find (fg)(x), we need to multiply f(x) and g(x). This can be done by substituting g(x) into f(x) and simplifying the expression.

f(x) = 4x² - 5

g(x) = x + 3

(fg)(x) = f(x) * g(x) = (4x² - 5) * (x + 3) = 4x³ + 12x² - 5x - 15

Therefore, the expression (fg)(x) simplifies to 4x^3 + 12x² - 5x - 15.

Answer:

Neither Troy nor Keith is correct.

Step-by-step explanation:

Neither Troy nor Keith is correct.

The value 0.9 is the same as the value 0.90.

The zeros after a decimal point are always insignificant unless they are followed by a number different from zero.

0.90 = 0.900 = 0.9000 = 0.90000 = ... = 0.9000000000

and all these can be easily written as 0.9, as the zeros after the decimal point do not change the value.

But 0.901, 0.9000004, 0.90002, and so on are all different, and the zeros are relevant, as they are followed by numbers different from zero.

Answer:

None of them is correct

0.9=0.90

Step-by-step explanation:

0.9>0.90 (not valid)

0.9<0.90 (not valid)

1. when dealing with decimals, the digits on the left hand side of the decimal point is a whole number.

The digits at the right hand side are considered individually.

2. the place value of the first digit is tenth, next is hundredth

3. if the last digits at the right hand side of the decimal point are zeros, then they are insignificant having no place value.

Hence, 0.9 is not greater 0.90

0.9 is not also less than 0.90,

because, the '0' at the right hand side of the decimal point, immediately after 9 is insignificant.

Therefore, 0.9=0.90
