Answer:
7.
8. <em>Correlation:</em> The more they spend in advertising dollars, the more sales they will get.
Step-by-step explanation:
The slope-intercept form is y=mx+b. The mx is the slope and the Y is the y-intercept.
All you have to do here is add the 3x to 10 so that the y is isolated.
y = 3x + 10
A correlation is like an "If... then" statement. But it's more written like:
"The more/less they do this, the number of this will increase/decrease."
The more they spend in advertising dollars, the number sales will increase.
Answer:
Step-by-step explanation:
Below is the pic of how this would be set up in order to determine what it is you are looking for. The angle is set in QI, and since csc A is the reciprocal of sin, the ratio is hypotenuse over side opposite. Solve for the missing side using Pythagorean's Theorem:
and
1369 = 144 + b² and
1225 = b² so
b = 35
The sec ratio is the reciprocal of cos, so if cos is adjacent over hypotenuse, the sec is hypotenuse over adjacent, which is 37/35
Answer:
r=
Step-by-step explanation:
The sum to infinity of a geometric series is calculated as
S∞ = ; | r | < 1
where a₁ is the first term and r the common ratio
here a₁ = 15 and S∞ = 45 , then
45 = ( multiply both sides by (1 - r ) )
45(1 - r) = 15 ( divide both sides by 45 )
1 - r = =
( subtract 1 from both sides )
- r = - 1 = -
( multiply both sides by - 1 )
r =
