Answer:
x=3
Step-by-step explanation:
First start by simplifying the right side which is -5(x-8)+4. Apply the distributive property to have -5x-5*-8+4. Then simplify to -5x+40+4, and then to -5x+44. Now you are left with 14+5x = -5x+44. Move -5x to the left side, which now makes it positive, and do 5x+5x to have 14+10x=44. Now move 14 to the right side and subtract it from 44 to get 10x=30. Now divide both sides by 10 to have x=3.
Answer:
x=-5
Step-by-step explanation:
14 + 5x = -5(x-8)+4
14+5x=-5x+40+4
14+5x=-5x+44
14+10x=44
10x=30
x=3
From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is
Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean [tex]\overline x[/tex] = 56
The formula for calculating the standard error can be expressed as:
[tex]S.E = \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]S.E = \dfrac{14}{\sqrt{49}}[/tex]
[tex]S.E = \dfrac{14}{7}[/tex]
S.E = 2
Therefore, the standard error of the mean = 2

sin^2(a+b)-sin^2(a-b)=sin(2a)sin(2b)
Answer:
Step-by-step explanation:
To prove sin(a+b)*sin(a-b)=cos^2b-cos^2a
we simplify the left side sin(a+b)*sin(a-b) first
sin(a+b) = sin a cos b + cos a sin b
sin(a-b) = sin a cos b - cos a sin b
sin(a+b)*sin(a-b) = (sin a cos b + cos a sin b) x (sin a cos b -cos a sin b)
sin a cos b((sin a cos b + cos a sin b) - cos a sin b (sin a cos b + cos a sin b)
open the bracket
sin a cos b(sin a cos b) + sin a cos b(cos a sin b) -cos a sin b (sin a cos b)+ cos a sin b ( cos a sin b)
sin²a cos²b + sin a cos b cos a sin b - cos a sin b sin a cos b + cos²a sin²b
sin²a cos²b + 0 + cos²a sin²b
sin²a cos²b + cos²a sin²b
sin²a = 1-cos² a
sin²b = 1-cos² b
(1-cos² a)cos² b - cos² a(1-cos² b)
= cos² b - cos² a cos² b - cos² a +cos² a cos² b
choose like terms
cos² b - cos² a - cos² a cos² b + cos² a cos² b = cos² b - cos² a + 0
cos² b - cos² a

Divide 5 liters in the ratio 11:5:9. Give your answer in milliters.
Answer: we have 2,200milliters, 1000milliters, 1800milliters.
Step-by-step explanation:
Step 1
1 Liter= 1000 millilitres
5 liters = 5000 millilitres
Step 2
Dividing 5000 ml in the ratio 11:5:9
First, we find the Total ratio = 11+5+9 = 25
Such that
First part = 11/25 x 5000 = 2,200milliters.
Second Part = 5/25 x 5000=1000milliters.
Third part =9/25 x 5000=1,800milliters.

The linear regression equation model obtained from the online regression equation is :
y = 0.75x + 5 ; where ;
y = weekly sales ; x = test score ; 0.75 = slope / gradient ; 5 = intercept
sales if the test score of a salesman is 65.
y = 0.75x + 5
x = 65
y = 0.75(65) + 5
y = 48.75 + 5
y = 53.75

what is the range of the function f (x)= -1/3 lx-1l-2?
Answer:
All real values less than or equal to -2 or (infinity, -2].
Step-by-step explanation:
The range of the function is the range of what the output can be. Let’s analyze the equation in parts.
Notice that |x-1| must always be greater than or equal to 0, so we know that 1/3|x-1| also must always be greater than or equal to 1/3*0 = 0.
With the negative, however, -1/3|x-1| must be less than or equal to -1/3*0 = 0.
Finally, we take the -2 into account. -1/3|x-1| - 2 must always be less than or equal to 0-2 = -2.
Therefore, the range is all real values less than or equal to -2, which can be written as (infinity, -2].
