Answer:

56-17-43+15

11. ........

Answer: 11

Step-by-step explanation:

We need to start by evaluating the problem, we can simplify this equation so its easier to solve.

So the new equation will be [tex]56-17-43+15[/tex].

56 - 17 = 39

39 - 43 = -4

-4 + 15 = 11.

So [tex]56-17-43+15 = 11[/tex].

11 is the answer.

A number raised to an exponent is the number multiplied by itself the number of times the exponent is.

The exponent is 3, so this means 0.25 is multiplied by itself 3 times.

0.25^3 = 0.25 x 0.25 x 0.25

Answer:0.100

Step-by-step explanation:

If you sed the rule of counting decimal places in the equation to find the number of decimal places in the answer you must not discard zeros too early. For example to multiply 0.25 by 0.4 you need 2+1 decimal places and the multiplication without a decimal point gives 0100. The answer is therefore 0.100.

Answer:

A.)

0.852 ; 0.999 ; 0.013

B.)

0.018 ; 0.593 ; 0.050

Step-by-step explanation:

Given :

Proportion of marketing personnel that are extrovert, p = 0.75

1 - p = 1 - 0.75 = 0.25

Proportion of computer programmers that are introverts, p = 0.55

1 - p = 1 - 0.55 = 0.45

According to binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

A.) n = 15

Probability that 10 or more are extrovert

P(x ≥ 10) = p(x = 10) + p(x = 11) +... p(x = 15)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 10) = 0.8516 = 0.852

Probability that 5 or more are extrovert :

P(x ≥ 5) = p(x = 5) + p(x = 6) +... p(x = 15)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 5) = 0.9999 = 0.999

Probability that all are extrovert :

P(x = 15) = 15C15 * 0.75^15 * 0.25^0

P(x = 15) = 1 * 0.75^15 * 0.25^0

P(x = 15) = 0.01336 = 0.013

B.

What is the probability that all are introverts?

n = 5

None are introvert :

P(x = 0) = 5C0 * 0.55^0 * 0.45^5

P(x = 0) = 1 * 1 * 0.0184528125

P(x = 0) = 0.01845 = 0.018

P(x ≥ 3) = p(3) + p(4) + p(5)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 3) = 0.5931 = 0.593

Probability that all are introvert

P(x = 5) = 5C5 * 0.55^5 * 0.45^0

P(x = 5) = 1 * 0.55^5 * 0.45^0

P(x = 5) = 0.0503 = 0.050

Answer:

2.99

Step-by-step explanation:

Answer:

She is not breaking even. The discounted price is .84t, which is less than t.

Step-by-step explanation:

Retail price= 1.4

1.4×.4= .56

40% of 1.4 is .56

Subtract 40% of 1.4 from the retail price because she is marking down.

(1.4)-(.56)=.84

So the discounted price is .84t

This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.

Answer: 88.5

Step-by-step explanation:

Step 1: Address the formula, input parameters & values.

Input parameters & values:

The given numbers are 82 & 95

Step 2: Find the sum of the given two numbers.

sum = 82 + 95 = 177

Step 3: Divide the sum by 2 to get the average.

average = 177/2

= 88.5

Answer:

4/3

Step-by-step explanation:

the answer is the second option

4/3

Multiply both sides by 2pi:

F(2pi) = sqrt(g/l)

Square both sides:

F^2 (2pi)^2 = g/l

Solve for l by dividing both sides by F^2 (2pi)^2

L = g/ F^2 (2pi)^2

Simplify:

L = g / 4pi^2(f^2)

[tex] \text{P}_{B}(r) = \dfrac{23}{40} [/tex]

The probability of drawing a red chip from bowl B will be ( 23 / 40 ).

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Bowl A contains three red and two white chips, and bowl B contains four red and three white chips. A chip is drawn at random from bowl A and transferred to bowl B.

The probability will be calculated as:-

[tex]\rm P_B(r)=P_A(r)P_B(r)+P_A(w)P_B(r)\\\\P_B(r) = (\dfrac{3}{5})(\dfrac{5}{8})+(\dfrac{2}{5}(\dfrac{4}{8})\\\\P_B(r)=\dfrac{23}{40}[/tex]

Therefore, the probability of drawing a red chip from bowl B will be ( 23 / 40 ).

Answer:

11 dimes and 9 quarters

Step-by-step explanation:

lets make x quarters and y dimes

Here is the equation we have so far:

x+y=20

BUT it can also be used to determine the values:

0.25x+0.10y=3.35

----------------------------------------------------------------------------

0.25x+0.10y=3.35

x+y=20

Im going to solve for quarters first.

Multiply everything by 0.25 on the bottom equation: 0.25x+0.25y=5

Now you have two equations:

0.25x+0.10y=3.35

and 0.25x+0.25y=5

subtract out the 0.25x

.15y=1.65

y=11

------------------------------------------------------------------------------

you have 11 dimes.

x+11=20

x=9

You have 9 quarters
