Answer:

the answer is 18.

Step-by-step explanation:

Answer:

When p=18, t=6

Step-by-step explanation:

If p and t are directly proportional, then:

p = k.t

Where k is the constant of proportionality.

We are given an initial condition: when p=12, then t=4. Substituting in the equation:

12 = k.4

Solving for k

k = 12/4 =3

The equation is:

p = 3t

Now we are required to find the value of t when p=18:

18 = 3t

Solving for t:

t = 18/3 = 6

t = 6

Thus, when p=18, t=6

do 33 divided by 2 (2= half) you get 16.5, you cant have half a stamp so remove the .5 to get 16, add 8 to get 24

Answer:

50

Step-by-step explanation:

If he sells half of his stamps and buys 8 more after and ended up with 33 I would take away 8 (33-8=25) and get 25 (which is the other half that he didn't sell). After figuring out what the other half was you would double this number and get your starting number which is 50 ( 25*2= 50)

So this is the set-up

50/2= 25+8= 33 and 33-8= 25*2= 50

Answer:

A) 0.1339

B) 0.8078

Step-by-step explanation:

The Poisson Distribution formula is given by;

P(x; μ) = (e^(-μ) × (μ^(x))/x!

We are given;

Variance = 0.5 per month

Now, in Poisson distribution, variance = mean.. Thus, mean μ = 0.5 per month

A) We want to find the probability that 4 typhoons will hit US in a year.

Thus, x = 4

But since it's for a year, then μ = 0.5 × 12 = 6

So;

P(x = 4) = (e^(-6) × (6^(4))/4!

P(x = 4) = 0.00247875 × 1296/24

P(X = 4) = 0.1339

B) probability that at least 2 typhoons will hit US in a given half-year is;

P(X ≥ 2) = 1 - P(X < 2)

P(X < 2) = P(X = 0) + P(X = 1)

In a half given year, μ = 0.5 × 6 = 3

P(X = 0) = (e^(-3) × (6^(0))/0!

P(X = 0) = 0.0498

P(X = 1) = (e^(-3) × (6^(1))/1!

P(X = 1) = 0.1494

P(X < 2) = 0.0498 + 0.1494

P(X < 2) = 0.1922

P(X ≥ 2) = 1 - 0.1922

P(X ≥ 2) = 0.8078

Answer:

k=8/3

Step-by-step explanation:

Let's solve your equation step-by-step.

4k+7=7k−1

Step 1: Subtract 7k from both sides.

4k+7−7k=7k−1−7k

−3k+7=−1

Step 2: Subtract 7 from both sides.

−3k+7−7=−1−7

−3k=−8

Step 3: Divide both sides by -3.

The value of k is equal to 8/3 for the given expression.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.

The given expression is  4 K + 7=7 k-1, the value of k is calculated as,

4K + 7=7k-1

Separate the like terms in the above equation and solve for the value of k,

4K + 7=7k-1

7k  - 4k = 7 + 1

3k = 8

k = 8/3

Therefore, the value of k will be 8/3 in the given equation. The value of k = 4 is wrong.

Answer:

a=2

Step-by-step explanation:

Slope is found by (y2-y1)/(x2-x1)

Using the points, that is (5-a)/(4a-2) = 1/2

multiply both sides by the denominator 4a-2

5-a = (1/2)(4a-2)

5-a=2a-1

put like terms on opposite sides by adding a to both sides so a terms on the right, adding 1 on both sides so numbers are on the left

6=3a

divide both sides by 3

a=2

Answer:

[tex]\boxed {\boxed {\sf m=\frac{1}{4}}}[/tex]

Step-by-step explanation:

The slope of a line can be found using the slope formula or dividing the change in y by the change in x.  

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are the points the line passes through.

We are given the points (2,1) and (6,2). Therefore:

[tex]x_1=2 \\y_1= 1\\x_2= 6\\y_2=2[/tex]

Substitute the points into the formula.

[tex]m=\frac{2-1}{6-2}[/tex]

Solve the numerator.

[tex]m=\frac{1}{6-2}[/tex]

Solve the denominator

[tex]m=\frac{1}{4}[/tex]

This fraction cannot be reduced further, so it is the slope. It can be written as a decimal too:

[tex]m= 0.25[/tex]

The slope of the line is 1/4 (0.25)

Answer:

135

Step-by-step explanation:

Supplementary means both angles equal 180 degrees when combined

180 - 45 = 135

Complementary means both equal 9 degrees when combined

if u think connect the lines of S and it makes and 8 for 180 and C makes 9 for 90

The measurement of the angle B should be considered as the 135 when the Angle A is given.

Since

Angle A and B are supplementary angles.

Angle A measures 45 degrees.

So we know that the sum of the supplementary angles is sum upto 180 degrees

So, it can be like

A + B = 180

45 + B = 180

B = 180 - 45

= 135 degrees

hence, The measurement of the angle B should be considered as the 135.

Answer:

 u = |u|(cos∝+cosβ+cosγ)

Step-by-step explanation:

Explanation

Proof:-

Given a vector  u = x₁ i + y₁j +z₁k

let O X, OY, O Z be the positive co-ordinate axes

P(x₁,y₁,z₁) be any point in the space

Let OP makes angles α,β,γ with co-ordinate axes OX , OY ,OZ .

The angle α,β,γ are known as direction angles and cosine of the angle

l =cosα , m= cosβ , n=cosγ

The perpendicular PA,PB,PC are drawn co-ordinate axes OX,OY,OZ respecctively

InΔOAP , ∠A =90° , cos∝ =[tex]\frac{x}{r}[/tex]

                                 x₁ = rcos∝

InΔOBP , ∠B =90° , cosβ =[tex]\frac{y}{r}[/tex]

                                 y₁ = rcosβ

InΔOCP , ∠C =90° , cosγ =[tex]\frac{z}{r}[/tex]

                                z₁ = rcosγ

Given   u = x₁ i + y₁j +z₁k

      |u| = [tex]\sqrt{(x_{1})^{2} +(x_{2} )^{2} +(x_{3} )^{2} }[/tex]

Therefore  u = x₁ i + y₁j +z₁k

               u = |u|(cos∝+cosβ+cosγ)

Answer:

The equation shows the temperature over time will be:

Hence, option (C) is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the rate of change or slope and b is the y-intercept

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

[tex]y = mx+b[/tex]

[tex]y = 3x + (-7)[/tex]

[tex]y = 3x - 7[/tex]

Therefore, the equation shows the temperature over time will be:

Hence, option (C) is correct.

Answer:

y = -4x - 9

Step-by-step explanation:

Use slope intercept form, y = mx + b, where m is the slope and b is the y intercept.

Since we are already given the slope and y intercept, we just have to plug them into the equation to find the equation:

y = mx + b

y = -4x - 9

So, y = -4x - 9 is the equation of the line in slope intercept form
