Answer:

7.3

Step-by-step explanation:

The mean is the average of the data set. This can be found by dividing the number of numbers in the data set by the sum of all the numbers.

So firso first, we have to find the sum:

7+9+7+9+15+0+11+13+11+1=73

There are 10 numbers.

73/10=7.3

The mean is 7.3

The line with equation x-3y-27=0 meets the parabola y²=4x at two points. Find their coordinates
lesantik [10]
x-3y-27=0\\
y^2=4x\\\\
x-3y-27=0\\
x=\frac{y^2}{4}\\\\
\frac{y^2}{4}-3y-27=0\\
y^2-12y-108=0\\
y^2-12y+36-144=0\\
(y-6)^2=144\\
y-6=-12 \vee y-6=12\\
y=-6 \vee y=18\\\\
x=\frac{(-6)^2}{4} \vee x=\frac{18^2}{4}\\
x=\frac{36}{4} \vee x=\frac{324}{4}\\
x=9 \vee x=81\\\\
\boxed{(9,-6),(81,18)}

Can anyone help me?pls
Mama L [17]

Answer/Step-by-step explanation:

Given:

C = right angle = 90°

BC = a = ?

AB = c = 12

AC = b = 9

Required:

a, <A, and <B

Solution:

✔️Find a using Pythagorean Theorem:

a = √(c² - b²)

a = √12² - 9²) = √63

a = 7.93725393 = 8 (nearest whole number)

✔️Find A by applying trigonometric ratio:

Thus,

Reference angle = A

Hypotenuse = 12

Adjacent = 9

Therefore,

cos(A) = \frac{adj}{hyp} = \frac{9}{12}

cos(A) = 0.75

A = cos^{-1}(0.75)

m<A = 41° (nearest whole number)

✔️Find B:

m<B = 180 - (90 + 41) (sum of interior angles of triangle)

m<B = 49°

X = 15.<br> PQ = SQ.<br> Find y, explain good for brainliest
eduard

Answer:

y = 25.

Step-by-step explanation:

PQ and RQ and SQ are congruent so

x + 10 = 2x - 5

15 = x.

So PQ = 15 + 10 = 25.

But PQ = RQ  = y, so

y = 25.

If they started at the south pole every direction is north.  Traversing the lattitudes (traveling 20 miles west) doesn't get you any farther from the pole.  

So they photographed south pole stuff, mostly snow.
