Answer:

80

Step-by-step explanation:

80 is the only number that is a multiple of ALL 2, 8 and 10

Answer:

the only answer that is a multiple of 2,8 and 10 between 49 and 95, is 80.

Answer: ok?

Step-by-step explanation:

Answer: draw a parallelogram like figure A and make it the same area of the unlabeled rectangle.

(a) The scale of the drawing is in centimeters.

(b) The scale factor of the drawing is 5 mm.

(c) The size of the spider's mate drawing should be 4 cm.

Given scale drawing of a spider is 5 cm long.

The actual spider is 10 mm long

(a) The scale of the drawing is in centimeters because the scale drawing of a spider given is in 5 centimeters,

(b) Scale factor:

The scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing.

In this case, the spider is 10 mm long but the drawing length is 5 cm.

Let’s convert both into the same units

5 cm - 50 mm

Original - 10 mm

Painting -50 mm

X - scale factor

50 = X * 10

X = 50/10 = 5 mm

The spider has been multiplied/ enlarged by a scale factor of 5 mm to draw the painting.

(c) Given the spider's mate is 8mm long.

Now for the drawing, we need to choose the scale factor as above to get the perfect measurement.

So, the 8 mm spider has been enlarged by a scale factor of 5 mm to get the size for drawing.

= 8 * 5

= 40 mm

= 4 cm

The size of the drawing should be 4 cm.

The value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4

The equation is given as

log₄(9x²) = log₂(5x - 8)

Apply the change of base law of logarithm

So, we have

log(9x²)/log(4) = log₂(5x - 8)

Express 4 s 2^2 and 9 as 3^2

So, we have

log(3x)²/log(2²) = log₂(5x - 8)

Apply the power law of logarithm

So, we have

2log(3x)/2log(2) = log₂(5x - 8)

Evaluate the quotient

So, we have

log(3x)/log(2) = log₂(5x - 8)

Apply the change of base law of logarithm

So, we have

log₂(3x) = log₂(5x - 8)

Cancel out the common base

So, we have

3x = 5x - 8

Collect the like terms

So, we have

3x - 5x = - 8

Evaluate the like terms

So, we have

-2x = - 8

Divide both sides by -2

So, we have

x = 4

Hence, the value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4

The numeric values of the function are given and explained as follows:

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

f(x) = 10000 + 1000x.

In which:

When x = -2, we have that:

f(-2) = 10000 + 1000(-2) = 8000.

Hence:

f(-2) = 8000, meaning a qualifying applicant with -2 siblings would receive a financial aid of $8,000. This interpretation does not make sense in the context of the problem.

When x = 4, we have that:

f(4) = 10000 + 1000(4) = 14,000.

Hence:

f(4) = 14,000, meaning a qualifying applicant with 4 siblings would receive a financial aid of $14,000. This interpretation makes sense in the context of the problem.

The number of siblings is a discrete number, and has to be of at least 0, hence:

The domain is: {x is a whole number and x ≥ 0}.

The correction option is B, It is out of control as one of these data points is more than 3 standard deviations from the mean.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Given that the candy produced by a company has a sugar level that is normally distributed with a mean of 16.1 grams and a standard deviation of 0.9 grams. Therefore, the maximum and the minimum weight of the candy can be,

Maximum weight = Mean + 3(Standard deviation)

                             = μ + 3σ

                             = 16.1 + 3(0.9)

                             = 16.1 + 2.7

                             = 18.8

Minimum weight = Mean - 3(Standard deviation)

                            = μ - 3σ

                            = 16.1 - 3(0.9)

                            = 16.1 - 2.7

                            = 13.4

Since one of the reading point, 19.4 is more than 3 standard deviations from the mean, therefore, it can be concluded that the process is out of control.

Hence, It is out of control as one of these data points is more than 3 standard deviations from the mean.

The sequence that can be modeled by the expression is T(n+1) = Tn + 8x - 5 where n >= 1

The expression of the first difference is given as

8x - 5

Rewrite properly as

d = 8x - 5

Where the common difference is represented by d

The common difference of an arithmetic sequence is calculated as

d = T2 - T1

So, we have

T2 - T1 = 8x - 5

Add T1 to both sides of the equation

So, we have

T2 = T1 + 8x - 5

Express 2 as 1 + 1

So, we have

T(1+1) = T1 + 8x - 5

Express 1 as n

So, we have

T(n+1) = Tn + 8x - 5 where n >= 1

The function is a continuous function. Then the value of variables a and b will be 2.5 and 3.5, respectively.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The piecewise function is given below.

[tex]f\left ( \rm x \right ) = \left\{\begin{matrix} \rm \dfrac{x^2 - 4}{x-2} \ or \ x + 2,& \rm x < 2\\ \rm ax^2 - bx + 1, & \rm 2\leq x < 3\\ \rm 4x - a + b, & \rm x \geq 3\end{matrix}\right.[/tex]

At x = 2, the function is continuous, then we have

2 + 2 = a(2²) - 2b + 1

4a - 2b = 3          ...1

At x = 3, the function is continuous, then we have

a(3²) - 3b + 1 = 4(3) - a + b

10a - 4b = 11        ...2

From equations 1 and 2, we have

8a - 10a = 6 - 11

2a = 5

a = 2.5

Then the value of b will be

10(2.5) - 4b = 11

25 - 4b = 11

4b = 14

b = 3.5

The value of the variable a and b will be 2.5 and 3.5, respectively.

The amount of time he spent on the bicycle is; 2.5 hours

The formula that shows the relationship between distance, speed and time is;

distance = velocity * time  

Let W = walking time

B = bicycling time

Thus, from the given data we have;

86 = 4W + 32B      

W + B = 4    

W = 4 - B  substitute 6-B for W in 86 = 4W + 32B to get;

86 = 4(4 - B) + 32B

86 = 16 - 4B + 32B

86 = 16 + 28B

70 = 28B

B = 70/28

B = 2.5 hours on the bicycle

W = 4 - 2.5= 1.5 hours walking

Answer:

x = 110°

Step-by-step explanation:

It is given that,

→ AB || EF

→ <ABC = <CEF

→ <CEF = <DEF

Then the value of <DEF will be,

→ <DEF = 70°

Now according to Exterior angle property of a triangle the value of x will be,

→ x = <DEF + <EFD

→ x = 70 + 40

→ [ x = 110° ]

Hence, the value of x is 110°.

Answer:

x = 110°

Given:

AB||EF means the sides are parallel and the angle is same in both.

Find the missing angle inside the triangle:

= 180° - (40° + 70°)

= 180° - 110°

= 70°

Now the missing angle and x sum ups to 180° on a straight line:

The average price per square foot in 2002 was approximately $85.86.

A mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a nonnegative integral power.

Example: a + bx + cx²

We have,

P(t) = 0.019t³ - 0.287t² + 3.073t + 55.130

Where t = number of years.

From 1992 to 2002 we have,

2002 - 1992 = 10 years

Now,

P(10) = 0.019(10)³ - 0.287(10)² + 3.073(10) + 55.130

P(10) = 19 - 28.7 + 30.73 + 55.130

P(10) = 85.86

Thus the average price per square foot in 2002 was approximately $85.86.
