In this item, we let x be the number of corns and Y represent soybeans. The sum of these variables is 400. This is represented by the equation,
                                             x + y = 400
The amount that needs to be earn by Tony is then represented by,
                                            200x + 300y ≥ $60,000

Two parallel lines are crossed by a transversal. Parallel lines r and s are cut by transversal q. On line s where it intersects
8_murik_8 [283]

Answer:

The value of d is 55

Step-by-step explanation:

Given:

r and s are two parallel lines

q is the Transversal

uppercase left angle is 125 degrees

The bottom right angle is d degrees

To Find:

The value of d = ?

Solution:

We know that the sum of supplementary angles is 180^{\circ}

Refer the diagram below,

Now

125^{\circ} +( x )= 180^{\circ}

( x )= 180^{\circ}-125^{\circ}

( x )= 55^{\circ}

Also we know that

Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.

So d  will also be 55^{\circ}

horsena [70]

Answer:  Expected value of the daily cost of operating the machine is 235.264.

Step-by-step explanation:

Since we have given that

E[x]= 0.96 repairs per day

And Var[x] = 0.96 repairs per day.

C=160+40x^2

E[c]=160+40E[x^2]\\\\E[c]=160+40(Var[x]+(E[x])^2)\\\\E[c]=160+40(0.96+0.96^2)\\\\E[c]=235.264

Hence, Expected value of the daily cost of operating the machine is 235.264.

A mechanical dart thrower throws darts independently each time, with probability 10% of hitting the bullseye in each attempt. Th
Arturiano [62]

Answer:

The probability of hitting the bullseye at least once in 6 attempts is 0.469.

Step-by-step explanation:

It is given that a mechanical dart thrower throws darts independently each time, with probability 10% of hitting the bullseye in each attempt.

The probability of hitting bullseye in each attempt, p = 0.10

The probability of not hitting bullseye in each attempt, q = 1-p = 1-0.10 = 0.90

Let x be the event of  hitting the bullseye.

We need to find the probability of hitting the bullseye at least once in 6 attempts.

P(x\geq 1)=1-P(x=0)       .... (1)

According to binomial expression

P(x=r)=^nC_rp^rq^{n-r}

where, n is total attempts, r is number of outcomes, p is probability of success and q is probability of failure.

The probability that the dart thrower not hits the bullseye in 6 attempts is

P(x=0)=^6C_0(0.10)^0(0.90)^{6-0}

P(x=0)=0.531441

Substitute the value of P(x=0) in (1).

P(x\geq 1)=1-0.531441

P(x\geq 1)=0.468559

P(x\geq 1)\approx 0.469

Therefore the probability of hitting the bullseye at least once in 6 attempts is 0.469.
