Answer: 36

Step-by-step explanation:

From the question, we are informed that six numbers has an average of 42. This means that the total number will be equal to:

= 42 × 6

= 252

When three of this numbers were removed the remaining three numbers had an average of 72. The total of this will be:

= 72 × 3

= 216

The sum of the removed numbers will be the difference between the two numbers above. This will be:

= 252 - 216

= 36

Answer:

t = $159

Step-by-step explanation:

3587-3250-178 = t

t = 159

Answer:

$-14.57

Step-by-step explanation:

the account is already below the zero limit, so for each day the account is below the required balance, there would be a charge of $5.95

After 2 days, the charge would be = $5.95 x 2 = $11.90

So, she would have to pay $11.90

Because she would be paying $11.90, there would be a negative sign in front of the amount

Total balance = $-11.90 -2.67 = $-14.57

Answer:

Answer:

Step-by-step explanation:

When two integers are in different sign, subtract and the result will have the bigger number sign

-7 + 9 = 2

Subtract and the 9 is the bigger number and its sign is +. So, the result is = +2 or 2

Solution

Step 1

Rate = (Portion/Base)*100%

Step 2

Rate = 16.3

Portion B = 4557

Let x reoresent the early

Step-by-step explanation:

distance divided by rate = time

d / (4 km/hr)   +  d/ (6 km/hr)    =  .75  hr                (.75 is 45 minutes)

d/4 + d/6 = .75

3d/12 + 2d/12 = .75

5d = 12 * .75

5d = 9

d = 9/5 km  = 1 4/5 km = 1.8 km

The mean of number of students who read fictional books is 4.32.

In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).

Given that, the summary of fictional books read by 37 students.

Total number of students =37

Sum =4(2)+10(3)+13(4)+10(7)

= 8+30+52+70

= 160

Now, mean =160/37

= 4.32

Therefore, the mean of number of books read by students is 4.32.

A = (2x+5)(x-4)=0

A = 2x²-8x +5x-20

A = 2x² -3x -20

as a quadratic equation is  :  ax² +bx +c

then  a = 2 ;  b = -3  and c = -20

Answer:

a = 2 ; b = -3  ; c = -20

Step-by- step explanation:

Use FOIL method.

                      (2x + 5)(x - 4) = 0

2x*x+ 2x*(-4 )+ 5*x + 5* (-4) = 0

                2x² - 8x + 5x - 20 =0

Combine like terms,

                       2x² - 3x - 20 = 0

Standard form: ax² + bx + x = 0

a = 2

b = -3

c = -20

the solution is:

u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)

so it will be 82.5

since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165

so H = V / LW

H = 165 / 5×3

H = 165 / 15

So the Answer is H = 11

the new paramecium population after one week will be 354.

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

r_max = 0.45 per week

N = 300

K = 500

Plugging these values into the logistic growth model, we get:

dN/dt = 0.45 * 300 * (500 - 300) / 500

dN/dt = 0.45 * 300 * 0.4

dN/dt = 54

So the paramecium population will grow by 54 individuals in one week.

To find the new population size after one week, we simply add the growth to the initial population:

N_new = N + dN/dt

N_new = 300 + 54

N_new = 354

Therefore, the new paramecium population after one week will be 354.

Given that when the temperature is between 35 and 50 degrees, it has historically rained 40% of the time. Also, historically, the month of April has had a temperature between 35 and 50 degrees on 25 days.

To find the probability that players will experience rain and a temperature between 35 and 50 degrees on April 12th, we will have to use the concept of conditional probability.

Conditional Probability is the probability of an event occurring given that another event has already occurred. Conditional Probability Formula: P(A|B) = P(A ∩ B) / P(B) where, P(A|B) is the probability of A given B,P(A ∩ B) is the probability of A and B, and P(B) is the probability of B.

Since the temperature between 35 and 50 degrees has historically rained 40% of the time, we can say that P(Rain | Temperature 35-50) = 0.4

Also, the probability of temperature between 35 and 50 degrees on April 12th can be calculated as P(Temperature 35-50) = 25 / 30 (as April has 30 days) = 5/6.

Using the conditional probability formula: P(Rain and Temperature 35-50) = P(Rain | Temperature 35-50) × P(Temperature 35-50)P(Rain and Temperature 35-50) = 0.4 × 5/6P(Rain and Temperature 35-50) = 0.3333 or 33.33%.

Therefore, the probability that players will experience rain and a temperature between 35 and 50 degrees on April 12th is 0.3333 or 33.33%.

The probability that at least one of the four selected calculators is defective is approximately 0.7775, or 77.75%.

To find the probability that at least one of the selected calculators is defective, we can use the concept of complementary probability. We calculate the probability of none of the selected calculators being defective and subtract it from 1.

The total number of calculators in the group is 20 (defective) + 29 (no defects) = 49 calculators.

The probability of selecting a non-defective calculator in one draw is 29/49. Therefore, the probability of selecting four non-defective calculators in a row is (29/49)^4.

To find the probability of at least one defective calculator, we subtract the probability of none being defective from 1:

P(at least one defective) = 1 - P(none defective)

                       = 1 - (29/49)^4

Using this formula, we can calculate the probability.

P(at least one defective) ≈ 1 - (29/49)^4 ≈ 1 - 0.2225 ≈ 0.7775

Therefore, the probability that at least one of the four selected calculators is defective is approximately 0.7775, or 77.75%.
