What is 737.303 - 43.866

This kind of problems are solved using Bernoulli's distribution. Everytime you have a win/lose scenario, and you know the probability [tex] p[/tex] of winning, and you want [tex]k[/tex] successes over [tex]n[/tex] trials, you have the following probability:

[tex]\displaystyle P(k\text{ successes over }n\text{ trials}) = \binom{n}{k}p^k(1-p)^{n-k} [/tex]

You want the probability of having at least three successes, i.e. you are interested in the cases k=3 and k=4. The corresponding probabilities are

[tex]\displaystyle P(3 \text{ successes}) = \binom{4}{3}0.6^3 \cdot 0.4 = 4\cdot 0.216 \cdot 0.4 = 0.3456[/tex]

[tex]\displaystyle P(4 \text{ successes}) = \binom{4}{4}0.6^4 = 0.1296 [/tex]

So, the total probability is [tex] 0.3456+0.1296 = 0.4752[/tex]

The value of s from the given equation is -1.5.

The given equation is 0.5s+1=7+4.5s.

We solve the given equation for s.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.

Now, the given equation can be solved as follows:

0.5s+1=7+4.5s

⇒0.5s-4.5s=7-1

⇒-4s=6

⇒s=-6/4

⇒s=-1.5

Therefore, the value of s is -1.5.

EXPLANATION

The volume of a cube is given by

[tex]V=l^3[/tex]

First we find the volume of the cube with side length [tex]\frac{3}{4}cm[/tex]

[tex]V_{Cube}=(\frac{3}{4})^3[/tex]

[tex]V_{Cube}=\frac{27}{64} cm^3[/tex]

Next, we find the volume of the cubic block with side length [tex]\frac{3}{8}cm[/tex]

[tex]V_{Block}=(\frac{3}{8})^3[/tex]

[tex]V_{Block}=\frac{27}{512} cm^3[/tex]

We divide the volume of the cube by the volume of the block to get the number of cubic blocks

[tex]Number\: of \: blocks=\frac{\frac{27}{64}} {\frac{27}{512}}[/tex]

[tex]Number\: of \: blocks=\frac{27}{64} \times \frac{512}{27}[/tex]

[tex]Number\: of \: blocks=\frac{1}{1} \times \frac{8}{1}=8[/tex]

Answer:

The correct answer is option A.

8 blocks are needed to fill the box.

Step-by-step explanation:

Given data:

Side length of a block = 3/8 cm

Side length of main block = 3/4 cm

How many blocks are needed to fit in main blocks = ?

Solution:

Volume  = length³

Volume of one simple block = (3/8)³ = 27/512 cm³

Volume of one Main block = (3/4)³ = 27/64 cm³

Blocks are needed to fit in main blocks = (27/64) ÷ (27/512) = 8

                                                            Answer = 8 blocks

Hence 8 simple small blocks of one side length 3/8 cm will needed to fit in the main block of side length 3/4 cm.

x       = 3       or        x      = -5

Answer:

From the comments below we see the missing part of the question is "in how many days will the ant farm consume 3 apples?"

The answer is 18.

Step-by-step explanation:

We will use a proportion to solve this.  It takes 3 days to consume 1/2 of an apple; this gives us the ratio

3/0.5

We want to know how many days, x, it will take to consume 3 apples; this gives us the ratio

x/3

Together this gives us the proportion

3/0.5 = x/3

Cross multiply:

3(3) = 0.5(x)

9 = 0.5x

Divide both sides by 0.5:

9/0.5 = 0.5x/0.5

18 = x

The ant farm will take 18 days to consume 3 apples.

Given that,

According to above information, calculation of data are as follows,

[tex]X = (3 \div 0.5) \times 3\\\\X = 6 \times 3[/tex]

X = 18

So, Total number of days required is 18 days.

Wrong answer = x

Correct answer = y

Total questions: x+y = 30

Rewrite for x: x = 30-y

Total points:

-8x + 7y = 0

replace x with 30-y

-8(30-y) + 7y = 0

Simplify:

-240 + 8y + 7y = 0

Combine like terms:

-240 + 15y = 0

Add 240 to each side:

15y = 240

Divide both sides by 15:

y = 240 / 15

y = 16

We know that if m and n are parallel, then we know that they have the same slope. We can call it x in this case.

Since we know that p is a perpendicular transversal, then we know it is the opposite and reciprocal of m. Therefore, we can label it as -1/x.

Since p = -1/x and n = x, we can tell they are perpendicular.

Parallel lines m and n, with transversal p, imply that if p is perpendicular to m (forming a 90-degree angle), it must also be perpendicular to n because parallel lines have the same inclination. Thus, the angle between n and p also has to be 90 degrees.

In the scenario presented, we're dealing with parallel lines m and n, and a transversal, p. The fact that p is perpendicular to m implies that the angle between m and p is 90 degrees. Now, since m and n are parallel, this means they have the same angle of inclination. So, the angle between n and p is also 90 degrees. This essentially means p is perpendicular to n as well.

Parallel lines have the property that they never intersect and are always equidistant. In geometry, when a line crosses two or more other lines, it is called a transversal. And when a line is perpendicular to another, it forms a 90-degree or right angle with the other line.

What is LCM of two numbers?

LCM means Lowest Common multiple. LCM of two numbers a and b is the lowest numbers which is divisible by both a and b

LCM can be calculated by division method and prime factorization method.

Also there is an important formula relating HCF and LCM

HCF [tex]\times[/tex] LCM = Product of two numbers

Here,

The number which is divisible by 2, 3 and 9 = LCM of 2, 3 and 9.

2 = 2

3 = 3

9 = 3 [tex]\times[/tex] 3

LCM = [tex]2 \times 3 \times 3[/tex] = 18

Next number divisible by 2, 3 and 9 = 18  + 18 = 36

But 36 does not lie between 10 and 20

So number between 10 and 20 divisible by 2, 3 and 9 = 18

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Coterminal angles are angles that have the same terminal sides in standard position.

Anytime we complete a full cycle( a complete revolution) we come back to the same terminal side.

Therefore to find all angles which are coterminal with [tex]-271\degree[/tex] we keep adding or subtracting [tex]360\degree[/tex].

For the given interval, that is, [tex]0\degree[/tex] to [tex]360\degree[/tex],

We add [tex]360\degree[/tex] so that we can obtain an angle coterminal with [tex]-271\degree[/tex] within this interval.

This means that

[tex]-271\degree[/tex] is coterminal with [tex]360\degree + \: -271\degree=89\degree[/tex]

The husband earns $42,000 per year.

Let's denote the husband's earnings as H.

According to the problem, the wife earns 16,000 less than twice what her husband earns. So, the wife's earnings can be represented as (2H - 16,000).

We know that together they earn 110,000 per year. This can be written as:

H + (2H - 16,000) = 110,000

Combining like terms, this equation simplifies to:

3H - 16,000 = 110,000

Add 16,000 to both sides to solve for H:

3H = 126,000

Divide both sides by 3:

H = 42,000

Therefore, the husband earns $42,000 per year.

[tex]x=\frac{14.5\degree}{3}+120\degree n\:or\:x=\frac{165.5\degree}{3} +120\degree n[/tex], for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.

EXPLANATION

We want to solve the trigonometric equation;

[tex]Sin(3x)=\frac{1}{4}[/tex]

Since sine ratio is positive, it means the argument,[tex](3x)[/tex] is either the first quadrant or second quadrant.

This implies that;

[tex](3x)=arcsin(\frac{1}{4})[/tex]

[tex](3x)=14.5\degree[/tex] in the first quadrant.

Or

[tex](3x)=180\degree-14.5\degree=165.5\degree[/tex] in the second quadrant.

Since the sine function has a period of [tex]360\degree[/tex], The general solution is given by

[tex](3x)=14.5\degree+360\degree n\:or\:(3x)=165.5\degree +360\degree n[/tex],for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.

Dividing through by 3, we obtain the final solution to be;

[tex]x=\frac{14.5\degree}{3}+120\degree n\:or\:x=\frac{165.5\degree}{3} +120\degree n[/tex], for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.
