Answer: 0.8333

Step-by-step explanation:

The conditional probability value rounded to 4 decimal places is : 0.2500

The relation can be used to find the conditional probability of events given :

P(HH | Atleast 1 head) = P(HHn(Atleast 1 H)) / P(Atleast 1 H)

P(Atleast 1 H) = P(HT + TH + HH)

P(Atleast 1 H) = P(HT + TH + HH) = 3(0.25) = 0.75

P(HHn(Atleast 1 H)) = P(HH) × P(Atleast 1 H) = 0.25 × 0.75 = 0.1875

Therefore, the conditional probability can be expressed as :

Therefore, P(HH | Atleast 1 head) is 0.25

Answer:

C

Step-by-step explanation:

The y intercept is where the line first crosses the y axis, so it would be positive 2. The slope is negative because it's diagonally going the left way, and its 3 because from one point to another it's 3 down and 1. The formula for a slope is rise/run, in this case it would be 3/1 which is 3.

Answer:

The answer would be the A (I included a picture to show you which one it is)

Step-by-step explanation:

Options D and E are out because it clearly says " bags can only carry up to 480 pound" and those are saying it can hold more than 480

Options B and C have a dashed line. If it has a dashed line that means that it is < or > and it is not because it says "up to" up to means it CAN hold exactly 480

So the only right answer would be Option A

You can use the method of calculating the percentage of an amount to find out the discount amount.

The discount price for the given condition was $205.2

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]

First we will find the marked price since the discount price was calculated on the marked price.

Since marked price was 150% of the cost price $456, thus,

[tex]\text{Marked price} = \dfrac{456}{100} \times 150 = \$684[/tex]

Thus, the marked price of the furniture was $684

Now, since the discount offered on the price was 30%, thus,

[tex]Discount = \dfrac{\text{Marked price}}{100} \times \text{Discount percent} =\dfrac{684}{100} \times 30\\\\Discount = \$205.2[/tex]

Thus,

The discount price for the given condition was $205.2

Answer:

Step-by-step explanation:

The electricity cost $489.76 more than the interest.

Thus, option C is correct.

Interest cost is the total measure of interest a borrower pays on an obligation commitment over the existence of the getting. Interest is paid on the obligation notwithstanding reimbursement of head.

The formula will be:

I = A - P

I = 663(1 + 0.1528/12)^(5*12) - 663

I = 663(1 + 0.1528/12)^60- 663

I = 1416.51 - 663

I = $753.51

The bill for electricity for 7 years and 52 weeks per year  will be

= 7 x 52 x 2.14

= $778.96

The electricity cost is bigger than the interest:

$778.96 is bigger than $753.51 by $25.45:

$778.96 - $753.51 = $25.45.

Therefore, option C is correct.

Answer: 8lbs

Step-by-step explanation:

The baby gained one pound

Assuming linear growth, the baby would weigh approximately 8 lbs after 4 weeks.

Assuming linear growth, we can use the concept of a slope to estimate the baby's weight after 4 weeks.

Given information:

Weight at birth (0 weeks): 7 lbs

Weight after 20 weeks: 12 lbs

We can calculate the rate of change (slope) of the baby's weight per week:

Slope = (Change in weight) / (Change in weeks)

Slope = (12 lbs - 7 lbs) / (20 weeks - 0 weeks)

Slope = 5 lbs / 20 weeks

Slope = 0.25 lbs/week

Now, using the slope, we can estimate the baby's weight after 4 weeks:

Estimated weight change = Slope * Number of weeks

Estimated weight change = 0.25 lbs/week * 4 weeks

Estimated weight change = 1 lb

So, the baby's weight after 4 weeks would be the initial weight (7 lbs) plus the estimated weight change (1 lb):

Estimated weight after 4 weeks = Initial weight + Estimated weight change

Estimated weight after 4 weeks = 7 lbs + 1 lb

Estimated weight after 4 weeks = 8 lbs

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

The condition which cannot be met for the numerical example a < b is the third condition a > 0 and b < 0.

Inequalities are expressions which are written on both sides separated by inequality symbols like <, >, ≤ and ≥.

The given numerical example is a < b.

When a > 0 and b < 0,

possible values of a are 1, 2, 3, ............

possible values of b are -1, -2, -3, .............

There is never a chance to get the positive values of a < negative values of b.
