can someone please help me and write out the answer​

Answer:

The data is a simple random sample from the population of interest.

Step-by-step explanation:

Conditions necessary to consider when constructing a confidence interval include using a large sample size, which should be greater Than or equal to 30 for n and a sample proportion of np ≤ 10. Importantly the sample must be a random sample drawn from the population, meaning that all the population of interest must have equal chances of being a part of the sample data. However, the scenariomabiveb, violates this condition as the sampling design is not completely randomized. Those who do not ply the route on that certain day have no Chaves of being part of the sample.

Answer: x=22.0 (nearest tenth)

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos, Tan.

To which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin and then the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos, then the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A' is for Opposite over Adjacent.

Because we have the Adjacent (angle next to 60°) and the Hypotenuse we would be using Cos.

So first you would write:

Cos 60=11/x

Then we would have to do the inverse to 'undo' the equation to get x on it's own. This would then look like:

x Cos 60=11

Then we do the inverse again:

x=11/Cos 60

so, x=22.0 (to the nearest tenth)

Hope this helps :)

The new selling price of the calculator will be R200.00.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, If a calculator is sold for R120.00.

Now, The original selling price is increased by a ratio 5 : 3, which can also be written as 5/3.

Therefore, The new selling price of the calculator will be,

= (5/3)×12000.

= 5×4000.

= 20000.

Answer:

25/49

Step-by-step explanation:

probability of red and red is (3/7)(3/7) = 9/49

Probability of blue and blue is (4/7)(4/7) = 16/49

Probability of same color = prob. of red and red or prob. of blue and blue

= 9/49 + 16/49

Answer:

Step-by-step explanation:

The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:

                            y - y₁ = m(x - x₁)

m = -5

(-2, 7)    ⇒   x₁ = -2,  y₁ = 7

y - 7 = -5(x - (-2))

y - 7 = -5(x + 2)            

(a, 2)   ⇒   2 - 7 = -5(a + 2)

                   -5 = -5a - 10

                   5a = 5 - 10

                     5a = -5

                       a = -1

Ruffly 6.5

Step-by-step explanation:

a^2+b^2=C^2

In this case we need to find a so we do c^2-b^2.

9.8^2-7.3^2=42.75

Square root of 42.75 is ruffly 6.5

Answer:

6.5 km

Step-by-step explanation:

hypotenuse (h)=9.8km

base(b)=7.3km

perpendicular (p)=?

we know,

p^2 =h^2-b^2

p^2=(9.8)^2-(7.8)^2

p^2= 96.04-53.29

p^2=42.75

(p)^2=(6.5)^2

p=6.5km

Step-by-step explanation:

Remark

The six exterior angles add up to 360. In fact the exterior angles of any closed convex figure adds up to 360.

You can try this with simple figures. An equalateral triangle has 3 equal exteror angles. They are all 120 degrees 3*120 = 360

A square has 4 exterior angles. All 4 of them are 90 degrees. The sum of them is 90 * 4 = 360

Givens

Angles

The Total is 360 degrees

Solution

3x + 6 + 7x - 11 + 62 + 4x + 7 + 6x - 5 + 41 = 360    Combine like terms

20x + 100 = 360                  Subtract 100 from both sides

20x = 360 - 100

20x = 260

x = 13
