RT and UW are parallel lines
Which angles are corresponding angles?

The correct answer is A. 0.84

The value of P(X<53) is 0.84 if the Z = 1 and normal distribution has a mean of 50 and a standard deviation of 3 option (A) is correct.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We know,

[tex]\rm Z = \dfrac{X-\mu}{SD}[/tex]

X = 53, μ = 50, and SD = 3

[tex]\rm Z = \dfrac{53-50}{3}[/tex]

Z = 1

From the Z table.

The value of P(X<53) = 0.84

Thus, the value of P(X<53) is 0.84 if the Z = 1 and normal distribution has a mean of 50 and a standard deviation of 3 option (A) is correct.

Answer:

arc a = 64°

arc b = 112°

Step-by-step explanation:

inscribed angles = 1/2 their arc

arc of 102° = 204° arc

arc a = 204° - 140° = 64°

arc of 92° = 184°

arc b = 360° - 184° - 64° = 112°

Answer:

-9

Step-by-step explanation:

you knew that it had to be a total of $60.60 and that the flat cost of the plan is $48. so you subtracted the flat cost from the total cost to get the amount that could be spent on gigabytes of data. since you knew that the gigabytes cost $3 each, you divided the remaining budget (12.60) by $3 and got the number of gigabytes that she can get.

Answer:

x = 14

NP = 3.66

NL = 8.01

Step-by-step explanation:

since △NPQ ∼ △NLM

<L = <P

3x + 18 = 60

3x = 60 - 18

3x = 42

x = 42/3

x = 14

Similarly;

PN/PL = QN/QM

y/8 = 3.2/7

Cross multiply

7y = 3.2* 8

7y = 25.6

y = 25.6/7

y = 3.66

Hence NP = 3.66

Also

NP/NQ = NL/NM

3.66/3.2 = NL/7

3.2NL = 7 * 3.66

3.2NL =  25.62

NL = 25.62/3.2

NL = 8.01

Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle. The value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).

The given tingle NPQ and triangle NLM are the similar triangle.

The length of the line PL is 8 cm.

Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle.

Value of the x-

As the two triangle are similar triangle, thus the length of the angle P is equal to the angle L. Therefore,

[tex]\angle L =\angle P\\ [/tex]

Keep the value of the angle from the diagram,

[tex]\begin{algined}\\ 3x+18&=60\\ 3x&=60-18\\\\ 3x&=42\\ x&=\dfrac{42}{3} \\ x&=14\\ \end[/tex]

Thus the value of the x is 14.

The length of the NP.

In the similar triangle the following ratios are equal,

[tex]\dfrac{PN}{PL} =\dfrac{QN}{QM} [/tex]

Put the values from the diagram,

[tex]\begin{aligned} \dfrac{y}{8}&=\dfrac{3.2}{7} \\ y&=\dfrac{3.2}{7} \times 8\\ y&=3.66\\ \end[/tex]

Value of y is equal to the length NP. Hence the length of the NP is equal to the 3.66 cm.

The length of the NL-

In the similar triangle the following ratios are equal,

[tex]\dfrac{NP}{NQ} =\dfrac{NL}{NM} [/tex]

Put the values from the diagram,

[tex]\begin{aligned} \dfrac{3.66}{3.2}&=\dfrac{NL}{7} \\ NL&=\dfrac{3.66}{3.2} \times 7\\ y&=8.01\\ \end[/tex]

Thus the length of the NL is equal to the 8.01 cm.

Hence the value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).

Step-by-step explanation:

The number line is saying that the solution could be any number less than -2.

The value included in the solution set for the inequality graph on the number line is -5.

The number line represents an inequality graph.

Let's use the range of value on the graph as x.

Therefore, the inequality on the number line will read as follows:

x < -2

Hence,

x less than -2 includes -3, -4, -5, -6, -7, -8 ..

This means that the extra cost for using 1 gigabyte of data will be $14.99, for using 2 gigabytes of data it will be $29.98, and so on.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The given function C(g) = 14.99g + 32 represents the cost, in dollars, for a cell phone plan that offers unlimited talk and text, with an additional charge for data usage.

The function has two parts:

The fixed cost of the plan is $32 (this is the cost you pay even if you don't use any data).

The variable cost of the data usage is $14.99 per gigabyte.

So, the cost of the plan for unlimited talk and text is the fixed cost, which is $32.

And, the additional cost for each gigabyte of data is the variable cost, which is $14.99.

This means that if you use 1 gigabyte of data, the additional cost will be $14.99, if you use 2 gigabytes of data, the additional cost will be $29.98, and so on.

Answer:

0.4470 = 44.70% probability of a random person on the street having an IQ score of less than 98.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

What is the probability of a random person on the street having an IQ score of less than 98?

This is the pvalue of Z when X = 98. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{98 - 100}{15}[/tex]

[tex]Z = -0.1333[/tex]

[tex]Z = -0.1333[/tex] has a pvalue of 0.4470

0.4470 = 44.70% probability of a random person on the street having an IQ score of less than 98.

Answer is 128 cubic inches

The volume of the given box is 64 inch³

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m³), a derived unit, is the SI unit of volume. Volume is another word for capacity.

The length, width, and height of a rectangular box are multiplied to get its volume.

As a result, the following formula may be used to determine the volume of an 8 inches by 4 inches by 2 inches rectangular box:

Volume is calculated using the formula LWH.

Volume is =8 * 4 * 2 inches.

64 cubic inches is the volume.

The rectangular box measures 8 by 4 by 2 inches and thus has a volume of 64 cubic inches.

Step-by-step explanation:

Giving the following information:

Purchase price=  $47,000  

Salvage value= $2,900  

Useful life= 5 years

To calculate the annual depreciation, we need to use the following formula:

Annual depreciation= (original cost - salvage value)/estimated life (years)

Annual depreciation= (47,000 - 2,900) / 5= $8,820

The accumulated depreciation is calculated as follow:

Accumulated depreciation= years of depreciation*annual depreciation

For year 4:

Accumulated depreciation= 8,820*4= $35,280

Finally, the book value is:

Book value= purchase price - accumulated depreciation

Linear speed =ωr=2π/86400×3960=11π/120 miles/s.

Step-by-step explanation:

The linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.

It is given that radius of equator of earth is 3960 miles.

We have to find the linear and angular speeds.

What do you mean by the linear speed ?

The linear speed of a point on the object is equal to the angular speed (ω) multiplied by the distance r.

As per the question ;

radius of equator of earth = 3960 miles

The linear speed will be ;

s = rθ / t

We know that ; at any point of equator would complete 360° or 2π radians revolutions every 24 hours.

So ;

s = (3960 miles × 2π) / 24 hour

s = 330π miles / hour

s ≅ 1036.73 miles / hour

And

The angular speed will be ;

ω = s / r

ω = 1036.73 / 3960 minutes

ω = 0.26 radian/hour

Thus , the linear speed and angular speed will be 1036.73 miles / hour and 0.26 radian / hour.
