Answer:

variation is NOT direct

Step-by-step explanation:

The +1 tells you the variation is not direct. The equation of direct variation is of the form ...

y = kx

with nothing added.

PLZ HELP NOW REALLY IMPORTANT :) 2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a). F

Alex_Xolod [135]

2. F = ma

a.) Solve this equation for a (isolate the a)

F = ma Divide m on both sides

$\frac{F}{m}=a$

b.) F = -25

m = 10

a = ?

$a = \frac{F}{m}$

$a = \frac{-25}{10}$

a = -2.5

c.) F = 25

a = 5

m = ?

F = ma

25 = m(5) Divide 5 on both sides

5 = m

(don't forget the units, because I forgot to put the units)

Answer:

The following are the answer to this question:

Step-by-step explanation:

In the given question the numeric value is missing which is defined in the attached file please fine it.

Calculating the probability of the distribution for x:

$\to f(x) = 0.19\ for \ x=14\\\\\to f(x) = 0.29 \ for\ x=7\\\\\to f(x) = 0.38\ for \ x=1\\\\\to f(x)=0.14 \ for \ x=0\\$

The formula for calculating the mean value:

$\bold{ E(X)= x \times f(x)}$

$=14 \times 0.19+7 \times 0.29+1 \times 0.38+0\times 0.14\\\\=2.66 + 2.03+0.38+ 0\\\\=5.07$

$\bold{E(X^2) = x^2 \times f(x)}$

$=14^2 \times 0.19+7^2 \times 0.29+1^2 \times 0.38+0^2 \times 0.14 \\\\=196 \times 0.19+ 49 \times 0.29+1 \times 0.38+0 \times 0.14\\\\= 37.24+ 14.21+ 0.38+0 \\\\=51.83$

use formula for calculating the Variance:

$\to \bold{\text{Variance}= E(X^2) -[E(X)]^2}$

$= 51.83 - (5.07)^2\\\\= 51.83 - 25.70\\\\=26.13$

calculating the value of standard deivation:

Standard Deivation (SD) = $\sqrt{Variance}$

$= \sqrt{26.13} \\\\=5.111$

Let a_n be the n th digit after the decimal point in

WITCHER [35]

I believe this should just be equal to
9π+5e−(⌊9π+5e⌋)=9π+5e−41
The first element in your sum should be the first digit after the decimal point times .1, so you have
.8
The next element in the sum is the second digit after the decimal place times .01, so you get
.8+.06=.86

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
