Answer: 30

Step-by-step explanation:

all angle degrees added up = 180 degrees as I said before.

180 = 102+48+M

180 = 150+M

M = 30

Answer:

Substitution property of equality

Step-by-step explanation:

Given

[tex]3x + 4y = 6[/tex]

[tex]x = 5[/tex]

[tex]3(5) + 4y = 6[/tex]

Required

Name the property used

From the question, we have that: [tex]x = 5[/tex]

This implies that 5 can be substituted for x in the given equation [tex]3x + 4y = 6[/tex]

So, when 5 is substituted for x, we have that:

[tex]3(5) + 4y = 6[/tex]

Conclusively, the property that was applies is the Substitution property of equality

Answer:

ST & TS are congruent

RST and UTS are congruent

Step-by-step explanation:

The question is not properly presented; however, I've added an attachment to give a clear picture of the question.

Required

State the property that justifies:

[tex]ST = TS[/tex]

Triangles [tex]RST = UTS[/tex]

From the question, we have that:

[tex]RS = UT[/tex]

[tex]RT = US[/tex]

In plane geometry, the length of ST is still the same as the length of TS.

This implies that:

[tex]ST = TS[/tex] because ST is congruent to TS

Moving further to determine the relationship between triangles [tex]RST\ \&\ UTS[/tex]

Comparing both triangles:

They have a similar side ST and TS because [tex]ST = TS[/tex]

And we also have that: [tex]RS = UT[/tex]

So, we can conclude that: [tex]RST = UTS[/tex] because they are congruent

Your question isn't 100% clear to me but I did my best:

1. RS = UT           Given

2. RT = US          Given

3. ST = TS           Reflexive Property of Congruence

4. RST = UTS      SSS (Side-Side-Side)

Answer:

x = 4

Step-by-step explanation:

Move all "x"s to one side of the equation:

(3x + 8) - x = (x + 16) - x

2x + 8 = 16

Subtract 8 from both sides so that all the numbers are on one side of the equation:

(2x + 8) - 8 = (16) - 8

2x = 8

Divide both sides of the equation by 2:

x = 4

A is the correct option:) Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons.

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

∆ABC ~ ∆AED, therefore,

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

Let BE = x

AB = x + 9

AE = 9

BC = 16

ED = 6

Plug in the values into the equation

[tex] \frac{x + 9}{9} = \frac{16}{6} [/tex]

[tex] \frac{x + 9}{9} = \frac{8}{3} [/tex]

Cross multiply

[tex] (x + 9)(3) = (8)(9) [/tex]

[tex] 3x + 27 = 72 [/tex]

Subtract 27 from each side

[tex] 3x = 72 - 27 [/tex]

[tex] 3x = 45 [/tex]

Divide both sides by 3

[tex] x = \frac{45}{3} [/tex]

[tex] x = 15 [/tex]

Segment BE = x = 15

The null hypothesis is  [tex]H_o : \mu_1 = \mu_2[/tex]

The alternative hypothesis  [tex]H_a : \mu_1 > \mu_2[/tex]

b

[tex]p-value = 0.232[/tex]

c

    The decision rule is  

Fail to reject the null hypothesis

Step-by-step explanation:

From the question we are told that

  The value given is  

S/N

1       7 5

2      4 3

3      8 7

4      8 8

5      7 9

6      7 5

7      6 5

Generally the sample mean for the first sample  is  mathematically represented as

        [tex]\= x _1 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x _1 = \frac{7 +4 + \cdots + 6}{7}[/tex]

=>     [tex]\= x _1 = 6.714[/tex]

Generally the sample mean for the second sample is mathematically represented as

        [tex]\= x _2 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x _2 = \frac{5 + 3+ \cdots + 5}{7}[/tex]

=>     [tex]\= x _2 = 6[/tex]

Generally the sample standard deviation  for the first sample  is  mathematically represented as

           [tex]s_1 = \sqrt{\frac{\sum (x_i - \= x_1)^2 }{n-1 } }[/tex]

=>       [tex]s_1 = \sqrt{\frac{ (7 - 6.714 )^2 +(4 - 6.714 )^2 + \cdots + (6 - 6.714 )^2 }{7-1 } }[/tex]

=>       [tex]s_1 = 1.905[/tex]

Generally the sample standard deviation  for the second  sample  is  mathematically represented as

           [tex]s_2 = \sqrt{\frac{\sum (x_i - \= x_2)^2 }{n-1 } }[/tex]

=>       [tex]s_2 = \sqrt{\frac{ (5 - 6.714 )^2 +(3 - 6.714 )^2 + \cdots + (5 - 6.714 )^2 }{7-1 } }[/tex]

=>       [tex]s_1 = 4.33[/tex]

Generally the pooled standard deviation is  

      [tex]s = \sqrt{\frac{(n_1 - 1 )s_1^2 + (n_2 - 1 )s_2^2}{n_1 + n_2 -2 } }[/tex]

=>    [tex]s = \sqrt{\frac{(7 - 1 )1.905^2 + (7 - 1 )4.333^2}{7 + 7 -2 } }[/tex]

=>    [tex]s = 1.766[/tex]

The null hypothesis is  [tex]H_o : \mu_1 = \mu_2[/tex]

The alternative hypothesis  [tex]H_a : \mu_1 > \mu_2[/tex]

Generally the test statistics is mathematically represented as

      [tex]t = \frac{\= x _1 - \= x_2 }{s * \sqrt{\frac{1}{n_1} + \frac{1}{n_2}} }[/tex]

=>   [tex]t = \frac{6.714 - 6 }{1.766 * \sqrt{\frac{1}{7} + \frac{1}{7}} }[/tex]

=>   [tex]t = 0.757[/tex]

Generally the degree of freedom is mathematically represented as

     [tex]df = n_1 + n_2 - 2[/tex]

=>   [tex]df = 7 + 7 - 2[/tex]

=>   [tex]df = 12[/tex]

From the t distribution table the probability of  [tex]t = 0.757[/tex] at a degree of freedom of [tex]df = 12[/tex] is  

     [tex]t_{ 0.757 , 12} = 0.232[/tex]

Generally the p-value is  

      [tex]p-value = t_{ 0.757 , 12} = 0.232[/tex]

From the values  obtained we see that [tex]p-value > \alpha[/tex]  hence  

   The decision rule is  

Fail to reject the null hypothesis

Answer:

BRO, u dont need to be a god :D, This is simple math and you just need to use your brains

Step-by-step explanation:

Given is a polynomial, and the values of the variables in it are given by showing what set are they an element of, right? It just gets easier from here

They tell us that 'z' is an element of set C, which stands for Complex Numbers.

And they also tell us that 'a' is an element of set Z, which stands for Integers, which are just numbers with a sign :).

They have also given us a root (solution) to the polynomial, which is also a complex number.

The two statements given are just there for us to verify that we are on the right track to the solution.

We can see that (z = 3 + i) which of course is a complex number, due to the presence of 'i', and 'a' is an integer for when we find its value.

Put it all together and we will get the answer.

Like this,

take the given value of 'z' and place it into the polynomial given, now keep your eyes open here. They said the value of z is as such when the polynomial is an equation which equals 0, so hence we get this:

P(z) = a(3+i)³ - 37(3+i)² + 66(3+i) - 10 = 0,

now just go on simplifying,

=> a(3³+i³+3×3²i+3×3i²) - 37(3²+2×3×i+i²) + 66×3 + 66×i - 10 = 0

=> a(27-i+27i-9i) - 37(9+6i-1) + 198 + 66i - 10 = 0

=> a(27+17i) - 37(8+6i) + 188 + 66i = 0

=>  a(27+17i) = 296 + 222i - 188 - 66i

=> a(27+17i) = 108 + 156i

=> a = (108+156i) / (27+17i)

=> a = (108+156i)(27-17i) / (27)² - (17i)²

=> a = (5568 + 2376i) / (699 + 289)

=> a = 5568 + 2376i / 1488

DONNEEE....yayyyy....lol

Answer:

The lengths of the sides of the playground are 14 feet, 6 feet, 7 feet

Step-by-step explanation:

At first, let us find the perimeter of the playground

∵ Perimeter of a triangle is P = S1 + S2 + S3

∵ The sides of the triangular playground are (2x) ft, (x - 1) ft, and x ft

∴ S1 = 2x, S2 = x - 1, S3 = x

→ Substitute them in the rule of the perimeter above

∵ P = 2x + x - 1 + x

→ Add the like terms

∴ P = (2x + x + x) - 1

∴ P = 4x - 1

∵ The perimeter of this playground is 27 feet

∴ P = 27

→ Equate the two values of P

∴ 4x - 1 = 27

→ Add 1 to both sides

∴ 4x - 1 + 1 = 27 + 1

∴ 4x = 28

→ Divide both sides by 4

∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{28}{4}[/tex]

∴ x = 7

→ Substitute the value of x in each side to find their lengths

∵ S1 = 2(7)

∴ S1 = 14 feet

∵ S2 = 7 - 1

∴ S2 = 6 feet

∵ S3 = 7 feet

∴ The lengths of the sides of the playground are 14 feet, 6 feet, 7 feet
