Answer:

The answer to your problem is, 0.275 0.273 0.400 and 0.300

Step-by-step explanation:

My calculation ( May not be correct )

P ( low iron or LI )  \(\frac{165}{600}\) = 0.275

P ( low pH | LI ) = \(\frac{45}{165}\) = 0.273

P ( low pH ) = \(\frac{150}{600}\) = 0.400

P ( LI | Low pH ) = \(\frac{45}{150}\) = 0.300

Thus by making these calculations the answer to your problem is, 0.275 0.273 0.400 and 0.300

Given that :-

Prove that :-

Taking RHS :-

= sin 2B/(5 – cos 2B)] = [(2 tan B)/(1 + tan2B)]/ [5 – {(1 – tan2B)/(1 + tan2B)}]

= (2 tan B)/ [5(1 + tan2B) – 1 + tan2B]

= (2 tan B)/[5 + 5 tan2B – 1 + tan2B)

= (2 tan B)/(4 + 6 tan2B)

= (2 tan B)/[2(2 + 3 tan2B)]

= tan B/(2 + 3 tan B tan B)

Dividing the numerator and denominator by 2,

= [(1/2) tan B]/ [1 + (3/2) tan B tan B]

= [(3/2) tan B – tan B]/[1 + tan A tan B] {from (i)}

= (tan A – tan B)/(1 + tan A tan B)

= tan(A – B) = LHS

The DJ will charge them $575.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given that,

Booking fee for DJ = $350

Rate for an hour = $45

Let x be the number of hours DJ is lasting.

Expression to find the total charge for x hours is 350 + 45x.

The Martins want to book the DJ for a party that will last 5 hours.

Cost for the DJ party for Martins = 350 + (45 × 5) = $575

Hence the cost for the DJ party booked by Martins is $575.

Answer:

2.-P = 0.38

3.-P [ Lb | Wt ]  =  0.788

Step-by-step explanation:

1.-Probability of choosing any box is, 1/3. So the probability of choosing the lucky box is 1/3

Let´s say the lucky box is the number 2 box  ( that consideration does not in any way change the problem generality)

Then we have

p₁ probability of choosing box  1 is 1/3   p₁´ Probability of win ticket is  0.12

p₂ probability of choosing box 2 is 1/3  p₂´Probability of win ticket is  0.90

p₃ probability of choosing box 3 is 1/3  p₃´ Probability of win ticket is  0.12

Then

P (of choosing a winning ticket is) = p₁*p₁´ + p₂*p₂´ +  p₃*p₃´

P  =  1/3*0.12 + 1/3*0.9 + 1/3*0.12

P  =  0.04 + 0.3 + 0.04

P = 0.38

3.- if I draw a winning ticket what is the probability it came from Lucky box

According to Bayes theorem

P [ Lb | Wt ]  =   P(Lb) * P[ Wt|Lb]/ P(Wt)

P(Lb) = 1/3  =  0.33333

P[Wt|Lb]  = 0.9

P(Wt) = 0.38

Then By substitution

P [ Lb | Wt ]  =  0.333 *  0.9 / 0.38

P [ Lb | Wt ]  =  0.788

Here is your solution for the problem.

Answer:

The total number of couples attending the banquet was 52.

Step-by-step explanation:

Given that a school reserved a banquet hall for the spring dance, and that, in addition to a $ 100 deposit, each couple must pay $ 20, to determine the total number of couples attending if the total cost of the banquet hall was $ 1,140 is due perform the following calculation:

100 + (20 x X) = 1140

20X = 1140 - 100

X = 1040/20

X = 52

Thus, the total number of couples attending the banquet was 52.

Answer:

y = (5/7)x + (75/7)

Step-by-step explanation:

If you ever find yourself in a math class where you have to write the equation of a line that goes through a certain point and has a certain slope, don't panic. There is a simple formula that can help you out. It's called the point-slope form and it looks like this:

y - y1 = m (x - x1)

It may look scary, but it's actually pretty easy to use. All you have to do is plug in the values that you know and solve for the ones that you don't. For example, let's say you have a line that passes through the point (-1, 10) and has a slope of 5/7. You can use the point-slope form to write the equation of the line like this:

y - 10 = (5/7) (x - (-1))

See? That wasn't so bad. Now you can simplify the equation by distributing the 5/7 and adding 10 to both sides. You get:

y = (5/7)x + (75/7)

And that's it! You have written the equation of the line in slope-intercept form, which is another way of writing the equation of a line. You can check your answer by plugging in the values of x and y from the original point and seeing if they make the equation true. If they do, you're good to go. If not, you made a mistake somewhere and you should go back and fix it.

Congratulations! You have learned how to use the point-slope form to write the equation of a line. Now you can impress your math teacher and your friends with your skills.  Remember, with great power comes great responsibility.

Answer:

the answer for this question is $4,769.97

Step-by-step explanation:

Note that each of the two equal payments due two and four years from now should be approximately $1,446.48

To find the amount of each of the two equal payments, we can use the concept of present value and set up an equation based on the given information.

The present value (PV) of a future payment can be calculated using the formula  -

PV = Payment / (1 + (r/n))\(^{nt}\))

Where  -

- PV is the present value

- Payment is the future payment

- r is the interest rate per compounding period

- n is the number of compounding periods per year

- t is the number of years

Given  -

- Payment 1  -  $3,150 due 18 months ago (1.5 years)

- Payment 2  -  $3,950 due in three years

- Interest rate  -  9.75% compounded semiannually

- Current payment  -  $2,850 today

- Two equal payments due two and four years from now

Let's solve for the amount of each payment  -

First, let's calculate the present value of Payment 1  -

PV1 = $3,150 / (1 + (0.0975/2))³

= $3,150 / (1 + 0.04875)³

= $3,150 / (1.04875)³

≈ $2,875.49

Next, let's calculate the present value of Payment 2  -

PV2 = $3,950 / (1 + (0.0975/2))⁽³ˣ²⁾

= $3,950 / (1 + 0.04875)⁶

= $3,950 / (1.04875)⁶

PV2 ≈ $2,717.47

Now, let's set up the equation using the present values  -

$2,850 + Payment 1 + Payment 2 = PV1 + PV2

$2,850 + Payment 1 + Payment 2 ≈ $2,875.49 + $2,717.47

Payment 1 + Payment 2 ≈ $2,875.49 + $2,717.47 - $2,850

Payment 1 + Payment 2 ≈ $5,742.96 - $2,850

Payment 1 + Payment 2 ≈ $2,892.96

Since the two equal payments are the same, let's denote each payment as P.

2P ≈ $2,892.96

Dividing both sides by 2  -

P ≈ $1,446.48

So , each of the two equal payments due two and four years from now should be approximately $1,446.48.

Answer:

Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance

There is a difference between the means

Step-by-step explanation:

Step(i):-

Given that mean of the Population = 5.9pounds/square inch

Given mean of the sample = 6.0pounds/square inch

Given that variance of the Population = 0.36

The standard deviation of the Population = √0.36 =0.6

Answer:

The Area of the trapezium is \(60cm^2\)

Step-by-step explanation:

Given,

Height (h)= 8cm

Sum of the parallel sides (a+b)= 15cm

Area of trapezium = \(1/2*h*(a+b)\)

                              =\(1/2*8*15\)

                              =\(4*15\)

Area of trapezium=60cm^2

Answer: Area = 60 cm²

Step-by-step explanation:

To find the area of a trapezium we use the formula

Area of trapezium = 1/2 (sum of parallel sides) × height

∴ Area = 1/2 ×15 cm × 8 cm

           = 60 cm²

Answer:

The y-intercept in this situation means that when the cab travels 0 miles, the total fee will be $14.00. This indicates that the cab service charges a flat fee of $14.00, regardless of the number of miles traveled.

Step-by-step explanation:

The y-intercept in this situation represents the base fee that the cab service charges regardless of distance traveled. In this case, when the cab travels 0 miles, the total fee is $14.00.

In this context, the y-intercept represents the base fee that the cab service charges, regardless of distance traveled. This is the amount you would pay for a cab ride of 0 miles. From the given table, we can't directly see the y-intercept, but we can infer it using the rate of change or slope, which represents the fee per mile. The amount increases by $1.50 for every additional mile (difference in y divided by difference in x), so to find the y-intercept, we back-calculate from one of the given points, like (2, 17). Subtracting 2 miles' worth of fees from $17 gives a y-intercept of $14. Therefore, when the cab travels 0 miles, the total fee is $14.00, which likely represents a starting charge or a minimum fare.
