Step-by-step explanation:

5/15 = n/9​

We can solve using cross products

15 n = 5*9

Answer:

D. Two angles are vertical angles if and only if their sides form two pairs of opposite rays

Step-by-step explanation:

A conditional statement is a statement that is is not truely ascertain except a particular condition is also true. This is done by using an IF statement. When a statement is biconditional, it means it is combined form of a conditional statement. The later is written by combining "two ifs" i.e IF and only IF. The statement is trying to ascertain two conditional statements at a time.

Given the statement "Two angles are vertical angles when their sides form two pairs of opposite rays.", we can see that it is made up to two statements.

1) Two angles are vertical angles

2) their sides form two pairs of opposite rays.

To ascertain the truthfulness of both statements, we will use the biconditional statement " if and only if". Hence the statement will become "Two angles are vertical angles if and only if their sides form two pairs of opposite rays"

Hence, option D is correct

Step-by-step explanation:

 let the almond be x pounds

and the peanuts be y pounds

so

x+y=1.6--------1

5.5x+2.5y=6.75---2

let us multiply both eqn 1 by 5.5 to to eleminate x

and subtract eqn 2 from the new eqn

  5.5x+5.5y=8.8-----3

 -5.5x+2.5y=6.75---2

   0+3x=2.05

divide both sides by 3 we have

x=2.05/3

x=0.68 pound

put x=0.68 in eqn 1 we have

0.68+y=1.6

y=1.6-0.68

y=0.91 pounds

Alicia gets $2.50*0.91= $2.275

Sarah gets  $5.50 *0.68=$3.74

The new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.

(a) The values of E(θ^1) and E(θ^2) are unknown without further information. Being unbiased estimators means that, on average, they provide estimates that are equal to the true population parameter θ. Therefore, we have:

E(θ^1) = θ

E(θ^2) = θ

(b) To find the expectation E(θ^3), we can use the linearity property of expectations:

E(θ^3) = E(aθ^1 + (1 - a)θ^2)

Since θ^1 and θ^2 are unbiased estimators, their expectations are equal to θ:

E(θ^3) = E(aθ^1 + (1 - a)θ^2) = aE(θ^1) + (1 - a)E(θ^2)

Using the values from part (a), we have:

E(θ^3) = aθ + (1 - a)θ = θ(a + 1 - a) = θ

Therefore, the new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.

Step-by-step explanation:

I will assume you want to put this in slope intercept form.

We need to solve for b in y = mx + b since we are given a point and the slope.

y = 0x + b

y = b

3 = b

y = 3

Isoquants for f(K, L) = 1/2 min{K, L} that produce exactly 10 goods and 25 goods can be graphed, with labeled points.

For function f(K, L) = 1/2 min{K, L}, we can graph the isoquants that represent the combinations of capital (K) and labor (L) that produce exactly 10 goods and 25 goods.

An isoquant represents all the combinations of inputs (K and L) that yield the same level of output. In this case, the isoquants will be curves that connect different combinations of K and L, where the output is constant at either 10 goods or 25 goods.

To graph the isoquant for 10 goods, we plot points where f(K, L) = 10. For example, if we let K = 4 and L = 4, the minimum of K and L is 4, so f(K, L) = 1/2 * 4 = 2 goods.

Since this is less than 10, we need to increase either K or L. We can try K = 8 and L = 4, where the minimum of K and L is still 4, and f(K, L) = 1/2 * 4 = 2 goods. Again, this is less than 10, so we increase K or L further.

Continuing this process, we can plot a few more points and connect them to obtain the isoquant for 10 goods.

Similarly, we can graph the isoquant for 25 goods by plotting points where f(K, L) = 25. For each point, we determine the minimum of K and L, multiply it by 1/2, and check if the result is equal to 25. By plotting and connecting several such points, we obtain the isoquant for 25 goods.

The probability that the dice lands on a four in the first three rolls is: 29%. The correct option is b.

Given that, A standard six-sided dice is repeatedly rolled until it lands on a four

We need to find the probability that the dice lands on a four in the first three rolls  i.e we need to find P(X=3) where X be the number of tosses before the first 4 shows up and let p be the probability of getting a 4.

The possible outcomes of a single dice roll = {1, 2, 3, 4, 5, 6}

So, the total number of possible outcomes of rolling the dice = 6

P(getting a 4 on a single toss)

p = 1/6

Then, the probability of not getting a 4 on a single toss:

q = 1 - 1/6

= 5/6.

Now, we know that the probability of getting a 4 on the third toss is the probability of not getting a 4 on the first two tosses and getting a 4 on the third toss.i.e,

P(4 on third toss) = q * q * p

Similarly, the probability of getting a 4 on the second toss is the probability of not getting a 4 on the first toss and getting a 4 on the second toss.

P(4 on second toss) = q * p

Now, P(X = 3) = P(4 on third toss) = q * q * p

= (5/6)² * (1/6)

= 25/216

≈ 0.1157

≈ 11.57%

Therefore, the probability that the dice lands on a four in the first three rolls is approximately 11.57%.

Rounding it to the nearest percentage, we get the answer as  b. 29%.Hence, option B is correct.

Answer: 3b^4(b+5-6b^3)

Step-by-step explanation:

Ana must pay $5,400,000 in interest for each monthly installment.

To calculate the interest payment for each monthly installment, we first need to determine the annual interest rate (IA) and then divide it by the number of months (12) to obtain the monthly interest rate.

Given:

To find the monthly interest rate, we divide the annual interest rate by 12:

Monthly interest rate = IA / 12

Let's calculate the monthly interest rate:

IA = 1.80000 * 200 = 360,000

Monthly interest rate = 360,000 / 12 = 30,000

Therefore, the monthly interest rate is $30,000.

Now, to calculate the interest payment for each monthly installment, we multiply the monthly interest rate by the loan amount:

Interest payment per installment = Monthly interest rate * Loan amount

Interest payment per installment = $30,000 * $180,000

Calculating this gives us:

Interest payment per installment = $5,400,000

Answer:

The price of the drink is: $4

and the bag of popcorn costed $5.5

Step-by-step explanation:

Let b=the price of each bag of popcorn

Let d=the price of each drink

One bag of popcorn costs $b, so 10 bags of popcorn cost 10b. One drink costs $d, so 6 drinks cost 6d. The total cost 10b+6d equals \$79:

10b+6d=79

Likewise, if 3 bags of popcorn and 5 drinks cost $36.50, then:

3b+5d=36.50

Write System of Equations:

10b+6d=79

3b+5d=36.50

The depth of the trapezoidal prism needs to be 0.5 feet (a) in order for the gutter to hold 10 cubic feet of water.

To find the depth of the trapezoidal prism, we can use the formula for the volume of a trapezoidal prism, which is given by V = (1/2)h(b1 + b2)L, where V is the volume, h is the depth, b1, and b2 are the lengths of the parallel sides of the trapezoid, and L is the length of the prism.

In this problem, the length of the front portion of the house is given as 32 feet. The two parallel sides of the trapezoid are 6 inches (0.5 feet) and 9 inches (0.75 feet), respectively. We are looking for the depth of the trapezoidal prism that will result in a volume of 10 cubic feet.

Using the formula for volume, we can substitute the given values and solve for h: 10 = (1/2)h(0.5 + 0.75)(32). Simplifying the equation, we get 10 = 41h. Solving for h, we find that h = 10/41 ≈ 0.2439 feet.

Converting the depth to inches, we have approximately 0.2439 * 12 ≈ 2.93 inches. Rounding to the nearest tenth, the depth of the trapezoidal prism should be approximately 0.5 feet or 6 inches to hold 10 cubic feet of water.
