Answer:

41.51

Step-by-step explanation:

We can find the value of x using the trigonometry identify.

Cos (41) = x/55

x = 55cos (41)

x = 41.51

ANSWER

[tex]x = 41.51[/tex]

EXPLANATION

The given triangle has a right angle.

We were given an acute angle that measures 41°

The hypotenuse of the given right triangle is 55.

Since x is adjacent to the given angle and we also know the hypotenuse, we use the cosine ratio to find x.

[tex] \cos(41 \degree) = \frac{x}{55} [/tex]

Therefore

[tex]x = 55 \cos(41 \degree) [/tex]

[tex]x = 41.509[/tex]

We round to the nearest hundredth to obtain,

[tex]x = 41.51[/tex]

Answer:

z = 1.3345

Step-by-step explanation:

The z-score for a given data point, say x, from a normal distribution with a given mean and population standard deviation is usually calculated using the formula;

[tex]z=\frac{x-mean}{standard deviation}[/tex]

The following information is available;

mean = 7

population standard deviation = 3.522

x = 11.7

We simply employ the above formula to determine the z-score associated with the 11.7 data point;

[tex]z=\frac{11.7-7}{3.522}=1.3345[/tex]

Answer:

B. 84%

Step-by-step explanation:

Given

Mean= π=75

Standard Deviation= σ=5

As we have to calculate the percentage of score less than 80, we will find the z-score of 80

z=(x-μ)/σ

=  (80-75)/5

=5/5

=1

The z-score table value for 1 is 0.8413.

For converting this value into percentage, the value will be multiplied by 100.

So,

Percentage of students whose score is less than 80 = 0.8413*100

=84.13%

Rounding off gives us : 84%

So option B is the correct answer..

Answer:

A. f(x)

B. g(x)

Step-by-step explanation:

The initial amount if the value of the function at x = 0.

Here that value is 2000 for the f(x) and 1000 for the g(x), so the f(x) has the higher initial value.

For the second part, by looking at the graph, you can determine that the function for the g(x) is 1000(3)^x (because the g(1) is 3000). Plugging in two for both the function, you get the f(x) = 8,000 and the g(x) = 9,000, so the g(x) has the greater amount of bacteria after two days.

Answer:

(statements listed below are correct)

Step-by-step explanation:

The correct statements are Option(A), Option(C) and Option(F).

A mathematical statement that consists of an equal symbol between two algebraic expressions with the same value is known as an equation.

Let the number be = S

When it is increased by 26 it becomes 42

S + 26 = 42( Option(A) and Option(C))

Subtract 26 from both the sides (Option(F))

S + 26 - 26 = 42 - 26

S = 16

Hence, it is proved that Option(A), Option(C) and Option(F) are correct.

Answer: Penny need to travel 49 feet before it hits the ground.

Step-by-step explanation:

Since we have given that

[tex]h(t)=-16t^2+305[/tex]

Here, h denotes the height of the penny

t denotes the time in seconds.

Now, t = 4 seconds

So, the penny needs to travel before it hits the ground is given by

[tex]h(4)=-16(4)^2+305\\\\h(4)=-16\times 16+305\\\\h(4)=256-+305\\\\h(4)=49\ feet[/tex]

Hence, Penny need to travel 49 feet before it hits the ground.

After 4 seconds, the penny needs to travel an additional 49 feet before it hits the ground.

The equation h(t) = -16t^2 + 305 represents the height of the penny at time t seconds. To find out how much further the penny needs to travel before it hits the ground after 4 seconds, we need to substitute t = 4 into the equation and solve for h.

h(4) = -16(4)^2 + 305

h(4) = -256 + 305

h(4) = 49 feet.

Therefore, the penny needs to travel an additional 49 feet before it hits the ground.

Answer:

52%

Step-by-step explanation:

We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.

Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.

Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;

= 0.65*0.8

= 0.52

Therefore, 52% of all customers get a burger and fries

Answer:

I wont tell you the answer. But, the answer is 3320/.8

Step-by-step explanation:

Whats 3320/.80?

The total cost of clicks $2656.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Per click charges= 80 cents

Total clicks= 3320

So, charges for 3320 clicks

= 3320 x 80

= 265600 cents

= $2656

Hence, the total cost of clicks $2656.

The expected value of the lottery game is -$0.62, suggesting a long-term average loss of 62 cents per game played. This value is calculated by considering the probability of each outcome and the associated gain or loss.

In order to calculate the expected value of the lottery game, we must first understand what expected value truly represents. The expected value is essentially a description of the average outcome of a series of events if these events are repeated many times. It's a statistical concept used to predict the long-range behavior of random events, such as lottery games.

The expected value is calculated as the sum of all possible values each multiplied by the probability of its occurrence. For the lottery game described, there are two possible outcomes: a win of $30,000 or a loss of $1.

The probability of winning is extremely low. In this game, the player is attempting to choose the correct 6 numbers out of 20, which is a 1 in 38,760 chance. Whereas, the probability of losing is extremely high, practically 38,759 out of 38,760.

Thus, the Expected Value (E) can be calculated as follows: (probability of winning x winnings) + (probability of losing x loss). Plugging in our values gives us an expected value of -$0.62, rounded to the nearest cent. This figure indicates that if one were to play this game repeatedly, their average loss per game would be about 62 cents.
