What is the following product?​

Answer:

[tex] DE = 7.3 [/tex]

[tex] EF = 10.3 [/tex]

[tex] FD = 7.3 [/tex]

∆DEF is an isosceles ∆

Step-by-step explanation:

To find the 3 side lengths of ∆DEF, use the distance formula, which is given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex].

Distance between D(-2, 3) and E(5, 5):

[tex] DE = \sqrt{(5 -(-2))^2 + (5 - 3)^2} [/tex]

[tex] DE = \sqrt{(7)^2 + (2)^2} [/tex]

[tex] DE = \sqrt{49 + 4} [/tex]

[tex] DE = \sqrt{53} [/tex]

[tex] DE = 7.3 [/tex] (nearest tenth)

Distance between E(5, 5) and F(-4, 10):

[tex] EF = \sqrt{(-4 - 5)^2 + (10 - 5)^2} [/tex]

[tex] EF = \sqrt{(-9)^2 + (5)^2} [/tex]

[tex] EF = \sqrt{81 + 25} [/tex]

[tex] EF = \sqrt{106} [/tex]

[tex] EF = 10.3 [/tex] (nearest tenth)

Distance between F(-4, 10) and D(-2, 3):

[tex] FD = \sqrt{(-2 -(-4))^2 + (3 - 10)^2} [/tex]

[tex] FD = \sqrt{(2)^2 + (-7)^2} [/tex]

[tex] FD = \sqrt{4 + 49} [/tex]

[tex] FD = \sqrt{53} [/tex]

[tex] FD = 7.3 [/tex] (nearest tenth)

∆DEF has two equal sides, DE and FD. Therefore, ∆DEF can be classified as an isosceles triangle.

  x = str(y) #defining a variable x that convert the value y in string  

  return three(x[0:3]) and three(x[1:4]) and three(x[2:5])#use return keyword to call the method three  

def three(x): #defining a method three that hold x variable as a parameter

   y = int(x) #use y to convert x in integer

   return y>=100 and (y%17==0 or y%23==0) #use return that gives a value which is divisiable by 17 or 23

Answer:

BC = 1.7

Step-by-step explanation:

Since, cosine of any angle (except right angle) represents the ratio of base length and hypotenuse.

Cosθ = [tex]\frac{\text{Base}}{\text{Hypotenuse}}[/tex]

From the given right triangle ΔACB,

[tex]\text{Cos}(\angle B) = \frac{\text{Base}}{\text{Hypotenuse}}[/tex]

              [tex]=\frac{BC}{AB}[/tex]

Cos(70°) [tex]=\frac{BC}{5}[/tex]

BC = 5Cos(70°)

     = 1.71

     ≈ 1.7

Explanation:

Drawing out a diagram usually helps with these types of problem. See the diagram below.

We have angle 3 and angle 4 as corresponding angles (since they are both in the north east corner of each four-corner configuration). Angle 1 = angle 3 is one pair of vertical angles and angle 2 = angle 4 is another pair of vertical angles. We see that angles 1 and 2 are corresponding angles in the south west corners of each four-corner configuration. That's why the original statement is always true.

Answer:

y= -0.6x + 4.4

Step-by-step explanation:

Answer:

0.000221

Step-by-step explanation:

Using the z score formula when a random number of samples is given =

z = (x-μ)/σ/√n, where

x is the raw score

μ is the population mean

σ is the population standard deviation = 7

n is random number of samples = 83

Note that:2.2 dollars = x-μ

z = 2.2/7/√8.3

z = 3.51402

Probability value from Z-Table:

P(x<27.7) = 0.99978

P(x>27.7) = 1 - P(x<27.7) = 0.00022069

Approximately = 0.000221

Hence, the probability that the sample mean would differ from the true mean by greater than 2.2 dollars if a sample of 83 5-gallon pails is randomly selected is 0.000221

Answer:

47.8

Step-by-step explanation:

What you want to do first is 5 1/5 - 5/12 which is 4.78,

then 1/6 x 2/3, which is 0.1,

then you do 4.78 divided by 0.1, which is 47.8

Answer:

The Availability of tablets A,B and C are equal

Step-by-step explanation:

Computation for Which tablet has better Availability

Using this formula

Availability of Tablet=MTBF/ ( MTBF + MTTR)

Where,

MTBF represent Mean Time Between Failures

MTTR represent Mean Time To Repair

Let plug in the formula

Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)

Availability of Tablet A= 0.999

Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )

Availability of Tablet B= 0.999

Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)

Availability of Tablet C= 0.999

Based on the above calculation the Availability of all the 3 tablets are equal

Therefore the Availability of tablets A,B and C are equal.

Look at a z table and look up z = 1.34.

The number associated with z = 1.34 is 0.9099

The p value is that value subtracted from 1.

P value = 1 − 0.9099 = 0. 0901

The  p - value for the test statistic should be considered as the 0.0901.

Since there is null and alternative hypotheses

so here we look at the z table and then the value should be 1.34

So, the value of z in 1.34 should be 0.9099

So, here the p-value should be  

=  1 - 0.9099

= 0.0901

hence, The  p - value for the test statistic should be considered as the 0.0901.

Answer:

Statement 2

Step-by-step explanation:

The exact value of the given trigonometric function cot(π/3) is √3/3.

The cotangent (cot) of an angle is defined as the ratio of the adjacent side to the opposite side of a right triangle.

Here, given that an angle of π/3, which is not a right angle.

So, we need to use the trigonometric identities to find the value of cot(π/3).

cot(θ) = 1/tan(θ)

where θ is an angle in radians.

We know that the tangent of π/3 is √3, as this is the opposite side (which is the same as the sine) divided by the adjacent side (which is the same as the cosine) of a 30-60-90 right triangle.

So, cot(π/3) can be expressed as:

cot(π/3) = 1/tan(π/3)

= 1/√3

Multiplying the numerator and denominator by √3/√3, we get:

cot(π/3) = √3/3

Therefore, the exact value of cot(π/3) is √3/3.
