Find the value of x to the nearest tenth

lorasvet [3.4K]

Answer:

Look below.

Step-by-step explanation:

Good ol' Pythagorean Theorem.

To find the short side of the larger triangle, we'll use this equation:

$a^{2} +b^{2} =c^{2} \\\\9^2+b^2=10^2\\81+b^2=100\\$

You can solve the rest on your own.

Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

$3^2+x^{2} = b^2$

Hope it helped! Also, there seems to be a help video, if you didn't understand this explanation, why don't you go ahead and watch it?

What causes our world to have day and night

True [87]

Answer: <u>the rotation of earth on its axis and revolution</u>

Step-by-step explanation:

The earth revolves round the sun and rotates round its own axis. The rotation of the earth causes day and night. The part of the earth which faces the sun experiences the day time whereas the part away from sun gets no sun light and hence the night. ... The axis of earth's rotation is tilted at 23.5 degrees.

A set of raw paired sample data is given below. Convert this raw data into paired ranks, and calculate the value of the rs test

SOVA2 [1]

here is the data set for the complete question

x: 18 21 19 21 20 21

y; 2 14 5 6 18 18

Answer:

B. 0.652

Step-by-step explanation:

x y rank of x rank of y d d²

18 2 1 1 0 0

21 14 4 4 0 0

19 5 2 2 0 0

21 6 4 3 1 1

20 18 3 5.5 -2.5 6.25

21 18 4 5.5 -1.5 2.25

∑d² = 8.5

rs = 1 - 6[∑di² + ∑m(m²-1)]/n(n²-1)

= 1 - 6[8.5 +{3(3²-10/12 + 2(2² - 1)/12}]/6(6²-1)

= 1 - 0.348

= 0.652

therefore option b is the right answer.

(3n-2)(4n+1)<br> how do i solve this by factoring?

Anni [7]

Answer:

$12n^2-5n-2$

The expression (3n-2)(4n+1) can be factored with the Distributive Property. It cannot be factored with a Least Common Multiple (LCM), for instance, because the terms within each set of parentheses are completely simplified.

Step-by-step explanation:

Part I

. $1. (3n-2)(4n+1)\\2. F.O.I.L.: 12n^2+3n-8n-2\\3. Simplify: 12n^2-5n-2\\$

Good luck to you!
