PLEASE HELP OR I WILL FAIL 1/7+3/7

Answer:

the last set: {1, 1, 1, 1, 2, 2, 2, 2}

Step-by-step explanation:

Notice the smallest standard deviation will come from the addition of the differences between the average value and each individual number in the set.

We notice that there is one set where all values are very close to the average . This is the set:

{1, 1, 1, 1, 2, 2, 2, 2} whose clear average is 1.5 , and therefore the deviations from the mean will produce contributions of 0.5 for each of the elements.

Answer:

CP = Rs 500

Step-by-step explanation:

Given that,

Selling price of a book, SP = Rs 550

Profit percent = 10%

We need to find the cost price of the book. The formula for profit percent is given by :

[tex]P\%=\dfrac{SP-CP}{CP}\times 100\\\\\dfrac{10}{100}=\dfrac{550-CP}{CP}\times 100\\\\\dfrac{1}{10}=\dfrac{550-CP}{CP}\\\\CP=5500-10CP\\\\CP+10CP=5500\\\\11CP=5500\\\\CP=500[/tex]

So, the cost price of the book is Rs 500.

Answer:(-4,6)

i dunno it in units lol sowwy

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

first we can simplify by dividing by r

[tex] \frac{9 {r}^{2} }{r} = \frac{9 \times r \times r}{r} = 9 \times r \times 1 = 9r[/tex]

the r on the bottom of the fraction will cancel out one of the r's on top, this happens because anything divided by itself is 1, thus r divided by r is 1

finally we can evaluate when r =3,

9r = 9(3) = 27

Answer:

x= 110°

Step-by-step explanation:

if you continue drawing the top purple line you will have a triangle with three angles

70° ; is given

180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)

180-70-40 = 70°; because sum of angles in a triangle is 180°

So angle x= 180 -70 = 110 because are a linear pair

Answer:

110 deg

Step-by-step explanation:

The supplement of the 140 deg angle measures 40 deg.

Draw a line through the vertex where angle x is that is parallel to the other two lines. That line splits angle x into two angles, an upper angle and a lower angle.

By alternate interior angles, the lower angle that is part of angle x measures 70 deg. Also by alternate interior angles, the upper angle that is part of angle x  measures 40 deg.

x = 70 + 40 = 110

Answer: 110 deg

Answer:

200 tulips

Step-by-step explanation:

The computation of the number of tulips are shown below:

Given that

Ratio of number of tulips to number of ratios is 2:3 we can write 8:12

And, the peonies to roses are 1:4 we can write as 3:12

So,

Tulips : Roses : Peonies

8:12:3

Now

Total units of flowers + 8 + 12 + 3

= 23

For tulips it would be

= 575 × 8 ÷ 23 units  

= 200 tulips

Answer:

7

Step-by-step explanation:

[tex]7f = 49 \\ divide \: both \: sides \: by \: 7 \\ \frac{7f}{7} = \frac{49}{7} \\ f = 7[/tex]

Answer:

43 degrees

Step-by-step explanation:

Using SOHCAHTOA, you are given the opposite and adjacent, the opp being 15 and the adj being 16.

Tan B = [tex]\frac{opp}{adj}[/tex]

Tan B = [tex]\frac{15}{16}[/tex]

      B = [tex]tan^{-1}[/tex]([tex]\frac{15}{16}[/tex])

      B = 43.15238973 degrees

Therefore, the answer is 43 degrees since you're looking for it to the nearest degree.

The distance between them is 59.92 ft

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle.

Given that, a scenario that is making an arrangement of a right-angled triangle, we need to find the base, [refer to the figure attached]

So, here we will use the Pythagoras theorem

75²+base² = 96²

base² = 96²-75²

base = √3591

base = 59.92

Hence, the distance between them is 59.92 ft

Answer: 0.06

Step-by-step explanation:

2/(3+25+2)=0.06

Let a(n) denote the n-th term in the GP. We're given

a(6) = 8a(10)

a(7) + a(8) = 192

In a geometric progression, consecutive terms are scaled up or down by a fixed ratio r such that

a(n) = r a(n - 1)

By substitution, we get

a(n) = r (r a(n - 2)) = r ² a(n - 2)

and we can continue the pattern down to the first term,

a(n) = r a(n - 1) = r ² a(n - 2) = r ³ a(n - 3) = … = rⁿ ⁻¹ a(1)

So we can rewrite the first two equations in terms of the first term of the GP a(1) and the common ratio r :

r ⁵ a(1) = 8r ⁹ a(1)

r ⁶ a(1) + r ⁷ a(1) = 192

Solve the first equation for r :

r ⁵ a(1) = 8r ⁹ a(1)   →   1 = 8r ⁴   →   r = 1/∜8 ≈ 0.5946

Solve the second equation for a(1) :

r ⁶ a(1) + r ⁷ a(1) = r ⁶ a(1) (1 + r ) = 1/(16√2) a(1) (1 + 1/∜8) = 192

→   a(1) = 6144 ∜2 / (1 + ∜8) ≈ 2724.48
