Answer:

p= 21

Explanation:

FIRST DO

3(21) -7

3 × 21 = 63

63 - 7 = 56

THEN DO

6(21) - 2

6 × 21 = 126

126 - 2 =  124

FINALLY

It needs to add up to 180°

124 + 56 = 180°

Therefore, the value of p = 21

Answer: the vector orthogonal is  ( 0, 26, -13 )

Step-by-step explanation:

Given that;

P(2, 0, 2),  Q(−2, 1, 4), R(7, 2, 6)

PQ = Q - P = (−2, 1, 4) - (2, 0, 2) = (-4, 1, 2)

PR = R - P = (7, 2, 6)  - (2, 0, 2) = ( 5, 2, 4)

SO

orthogonal vector = PQ × PR

= ║ i    j    k

    -4   1   2          = i(1×4 - 2×2) + j(5×2 - (-4×4)) + k(-4×2 - 5×1) = 0i + 26j - 13k

     5   2   4  ║

= ( 0, 26, -13 )

Therefore the vector orthogonal is  ( 0, 26, -13 )

Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

Answer:

39.39%

Step-by-step explanation:

There's a nice little formula that is used to find percentage change which works regardless of if it's an increase or decrease.

[tex]Percent~Change = |\frac{New~Value~-~Original~Value}{Original~Value}| * 100[/tex]

1 - Understanding the equation

The '|'s which are surrounding the fraction are absolute value symbols in mathematics,

Absolute value means the positive value of anything inside

Examples:

| -8 | = 8

| 8 |  = 8

and

| -2 | = 2

| 2 |  = 2

the * 100 means you multiply (the * symbol means multiply) by 100.

We do this to get it into a percent.

3 - Assign numbers to the values from our equation

Original Value (What it changed from): 330

New Value (What it changed to): 200

3 - Plug in our values into our variables from our equation[tex]Percent~Change = |\frac{200-330}{330}| * 100 = |\frac{-130}{330}| = = |-0.39...| * 100 = 0.3939... *100 =[/tex]

Our percent change is 39.39%, and with our percent in which is discounted being the same, we have our answer.

Answer:

It is False.

Step-by-step explanation:

When you substitute the coordinates into the inequality equation :

[tex]y \geqslant 10x + 5[/tex]

[tex]let \: x = 5,y = 10[/tex]

[tex]10 \geqslant 10(5) + 5[/tex]

[tex]10 \geqslant 55 \: (false)[/tex]

Therefore, 10 isn't greater than 55.

[tex]\qquad\quad {:}\longmapsto\sf x=5 [/tex]

[tex]\qquad\quad {:}\longmapsto\sf y=10 [/tex]

[tex]\qquad\quad {:}\longmapsto\sf y \geqslant 10x+5[/tex]

[tex]\qquad\quad {:}\longmapsto\sf 10 \geqslant 10 (5)+5 [/tex]

[tex]\qquad\quad {:}\longmapsto\sf 10 \geqslant 50+5 [/tex]

[tex]\qquad\quad {:}\longmapsto\sf 10 \lt 55 [/tex]

[tex]\therefore \sf y \geqslant 10x+5 {\boxed {False}}[/tex]

NOTE: NONE OF THE OPTIONS GIVEN IS CORRECT. THIS IS THE CORRECT ANSWER.

AB = EF, BC = FG, AC = EG

Step-by-step explanation:

According to the SSS Congruence statement, for ∆ABC to be congruent to ∆EFG, all the sides of ∆ABC must be congruent to all the corresponding sides of ∆EFG.

This means that:

AB must be congruent to EF

BC must be congruent to FG

AC must be congruent to EG

Therefore, additional information is needed to prove that triangles ABC and EFG are congruent by the SSS triangle congruence theorem are:

AB = EF, BC = FG, AC = EG

The perimeter of the marked polygon is 26 units.

Perimeter is the distance around the outside of a shape.

Given is a polygon, ABCDEF,

Using the distance formula, we have,

(P, Q) = √ (x2 – x1)² + (y2 – y1)².

AB = 3 units

BC = 4 units

CD = 3 units

DE = 7 units

EF = 6 units

FA = 3 units

Perimeter = AB+BC+CD+DE+EF+FA = 3+4+3+7+6+3 = 26 units.

Hence, The perimeter of the marked polygon is 26 units.

We finds out how many 7s are in 34

5 * 7 is 35, so it must be 4.

when 34 is divided by 7, the answer would be 4 and 6 remainders.

put the remainders back into the nominator part of the fraction.

Answer:

0.42 ft

0.92 ft

Step-by-step explanation:

Width of mural on painting = 5 inches

Height of mural on painting = 11 inches

12 inches of the painting represents 1 foot of the mural

1 inch of the painting represenets [tex]\dfrac{1}{12}[/tex] foot of the mural.

[tex]5\ \text{inches}=5\times \dfrac{1}{12}=0.42\ \text{ft}[/tex]

[tex]11\ \text{inches}=11\times\dfrac{1}{12}=0.92\ \text{ft}[/tex]

The width of the mural is 0.42 ft and height of the mural is 0.92 ft.

The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.

Since

Arnold painted the picture on a paper that is 5 inches wide and 11 inches tall. Arnold is using a scale in which 12 inch represents 1 foot to paint the mural.

So here the width should be 5 of 1 by 12 should be 0.42 feet

And, the height should be 11 of 1 by 12 should be 0.92 ft.

Hence, The height and width of the actual mural into the boxes is 0.92 ft and 0.42 ft.

Answer: 0.111947

Step-by-step explanation:

Let x be a binomial variable that represents the number of people with​ 20-20 vision.

Given: The probability that an individual has​ 20-20 vision: p= 0.13

Sample size : n= 24

Binomial probability distribution formula:

[tex]P(X=x)=^nC_xp^x(1-p)^{n-x}[/tex]

The probability of finding five people with​ 20-20 vision :

[tex]P(X=5)=\ ^{24}C_5(0.13)^5(1-0.13)^{24-5}\\\\=\dfrac{24!}{5!19!}(0.13)^5(0.87)^{19}\\\\=0.111946975387\approx0.111947[/tex]

Hence, the required probability = 0.111947

The probability of finding five people with 20-20 vision is 0.0461.

The formula for the Binomial Probability is,

[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}[/tex]

Given that,

[tex]p = 0.13\\1 - p = 0.87\\n = 72\\x = 5[/tex]

Substituting the given values into the above formula we get,

[tex]P(X = x) =(\frac{n!}{x!(n-x)!} )\times p^x \times (1-p)^{n-x}\\P(X=5)=(\frac{72!}{5!(72-5)!} ) (0.13)^5(0.87)^{72-5}\\P(X=5)=0.0461[/tex]

The 99% confidence interval of the  standard deviation of the pulse rates of men is  

       [tex][ 7.949 \  \ , \  14.387 ][/tex]

Step-by-step explanation:

From the question we are told that

  The  sample size is  n  =  40

  The mean is  [tex]\= x = 67.3 \ beats \ per \ minute[/tex]

  The standard deviation is  [tex]s = 10.3 \ beats \ per \ minute[/tex]

Generally the degree of freedom is mathematically represented as

     [tex]df = n- 1[/tex]

=>  [tex]df = 40- 1[/tex]

=>  [tex]df = 39[/tex]

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 99 ) \%[/tex]

=>   [tex]\alpha = 0.01[/tex]

Generally from the chi distribution table the critical value  of   at a degree of freedom of is  

   [tex]X^2 _{\frac{\alpha }{2} , 39} =  65.476[/tex]

Generally from the chi distribution table the critical value  of   at a degree of freedom of is  

   [tex]X^2 _{1- \frac{\alpha }{2} , 39} =  19.996[/tex]

Generally the 99% confidence interval of the standard deviation of the pulse rates of men is mathematically represented as

  [tex]s \sqrt{\frac{n- 1}{X^2_{1- \frac{\alpha }{2} , n-1} } }\  \ , \ s \sqrt{\frac{n- 1}{X^2_{\frac{\alpha }{2} , n-1} } }[/tex]

=>  [tex]10.3 \sqrt{\frac{40- 1}{65.476} }\  \ , \ 10.3 \sqrt{\frac{40- 1}{19.996} }[/tex]
