what number is a solution of the inequality 3<3x-15

Answer:

Step-by-step explanation:

Given the function f(x) = (5x+1)/2

We are to find the inverse first as shown;

let y = f(x)

y = (5x+1)/2

Replace y with x

x = (5y+1)/2

Make y the subject of the formula;

2x = 5y+1

5y = 2x-1

y = (2x-1)/5

f^-1(x) = (2x-1)/5

f^-1(8) = 2(8)-1/5

f^-1(8) = 16-1/5

f^-1(8) = 15/5

f^-1(8) = 3

Hence the answer is 3

169 knives

Step-by-step explanation:

What we know:

ZW threw 200 knives at Jotaro, then adds one more. This makes 201 knives, initially.

However, the RRD subtracts 32 from 201, making it 169 knives that ZW threw.

201 - 30 - 2 = 171 - 2 = 169 knives

Answer:

63.75

Step-by-step explanation:

this is a geometric progression with a common ratio of -1/2

the formula for the sum of first n numbers is

Sn = (a1(1-r^n)) / 1 - r

so S8 = (32*(1 - 1/2^8)) / (1 - 1/2)

32*(255/256) / 0.5

Sn= 255 / 4 = 63.75

Step-by-step explanation:

Step one:

given data

Each bagel cost $2.00

Also, the cost function is given as

[tex]F(x)=2x[/tex]

Step two:

Required

The total cost of bagels purchased

From the cost function, we can see already that Ayden Bought 2 Bagel, hence if one bagel cost $2 then

[tex]F(x)=2(2)\\\\F(x)=4[/tex]

The two bagels will cost $4

The expression  a³ + 3 a² b - 4 a b - 11 b + 7 will have 5 terms in it.

We are given the expression:

a³ + 3 a² b - 4 a b - 11 b + 7

We need to find the number of terms this expression has.

We can see that, this expression has 5 terms.

The first term will be a³.

The second one will be 3 a² b.

The third one will be 4 a b.

The fourth one will be 11 b.

And the fifth one will be 7.

Therefore, we get that, the expression  a³ + 3 a² b - 4 a b - 11 b + 7 will have 5 terms in it.

The aircraft and the submarine are 255 m apart

Step-by-step explanation:

Here, we want to calculate the distance between the submarine and the aircraft

From the question;

The aircraft is 200 m above the surface and the submarine is 55 m below ( this is same as an altitude of -55)

So the distance between the two will be;

200-(-55) = 255 m

Answer:

255m

Step-by-step explanation:

The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test  grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.

Given :

The generalized regression equation is given below:

Y = a + bX   --- (1)

where b is given by the formula:

[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.

b = 1.15

and the formula of a is given below:

[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'a'.

a = -12.41

Now, substitute the values of a and b in the equation (1).

Y = -12.41 + 1.15x

Now, at x = 49 the value of Y becomes:

Y = -12.41 + 1.15(49)

Y = 43.94

Y [tex]\approx[/tex] 44

thx for points

The equation of the straight line that has x-intercept 1 and y-intercept 4 is:

4x - y = 4

"A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point."

Given, the line has a x-intercept of 1 and y-intercept of 4. T

Therefore, the line passes through the points (1, 0) and (0, 4).

Now, we can find the slope of the line 'm' that passes through those either points.

Therefore, (x₁ - x₂) = m(y₁ - y₂)

⇒ (1 - 0) = m(0 - 4)

⇒ m = [tex]\frac{1}{4}[/tex]

Now, the equation of the line that has x-intercept 1 and y-intercept 4 is:

(x - x₁) = m(y - y₁)

⇒ (x - 1) =      [tex]\frac{1}{4}[/tex](y - 0)

⇒ 4(x - 1) = y

⇒ 4x - y = 4

Given that :

Correlation Coefficient = 0.793

The correlation Coefficient gives the strength of relationship between linear variables ranging from - 1 to 1.with values close to either - 1 or 1 depicting strong negative or positive correlation respectively, while values close to 0 signifies a weak correlation. Since the correlation Coefficient Given by the model is close to 1(0.793) one can be moderately confident that the value obtained from the model will be reasonably close to the actual value.

When the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, B. both balls hit the ground at the same time.

When an object moves through the air, air resistance acts as a force. When a body is moving through the air, this force works in the opposite direction. A frictional force is applied to the moving body by air resistance. Air resistance causes a body's speed to slow down as it moves.

Because air resistance slows down the motion of the falling object, it impacts acceleration during a fall to a lesser extent than gravity (g). The object's surface area and speed both influence how much it slows down.

Therefore, when the 100 g ball and a 50 g ball are dropped from a tower. both balls are the same size and there is no air resistance, both balls hit the ground at the same time.
