Hello there, this problem is just basic addition, here is what it would look like
[tex]52.31+25.90[/tex]
Solve it and we get 78.21
Amount earned on Saturday = $ 52.31
Amount earned on Sunday = $ 25.90
Total amount earned
= $ 52.31 + $ 25.90
= $ 78.21
Therefore, Tara earned $ 78.21 in total. Hope this helps.
Have a nice day.

If the standard deviation of of the values 2,4, 6,8 is 2.236, the the standard deviation of the values 4, 8, 12, 20 is?
Answer:
5.916
count N : 4
Sum, Ex : 44
Mean , M
Variance , o2 : 35
Step-by-step explanation:
we are creating the mean value of the squares of the differences of each data point to the mean value (variance), and then we pull the square root to bring the differences back to the same dimension as the basic data points.
and since we are dealing with the whole "population" of data points and not only with a sample of a much larger set of data points, that mean value of the differences is a true mean value (divide by n = the number of data points). if we would deal with a sample of a much larger population, we would divide by n-1.
so, how does this work in practice ?
let's go first for the given example :
2, 4, 6, 8.
the mean value is : (2+4+6+8)/4 = 20/4 = 5.
the variance (mean value of the squared differences of each data point to the mean value) :
((2-5)² + (4-5)² + (6-5)² + (8-5)²)/4 = (9+1+1+9)/4 = 20/4 = 5.
the standard deviation is the square root of the variance.
so,
SD = sqrt(5) = 2.236067977...
now for the given problem :
4, 8, 12, 20
the mean value is : (4+8+12+20)/4 = 44/4 = 11.
the variance (mean value of the squared differences of each data point to the mean value) :
((4-11)² + (8-11)² + (12-11)² + (20-11)²)/4 = (49+9+1+81)/4 = 140/4 = 35.
the standard deviation is the square root of the variance.
so,
SD = sqrt(35) = 5.916079783... ≈ 5.916

what is the equation of a line whose slope is -2 and whose y-intercept is 4?
Answer:
y=-2x+4
Step-by-step explanation:
if y is 4..it means x intercept is 0
gradient is -2
and we know gradient is the change in y /change in X
so: we let the second intercepts to be (x,y)
so y-4/x-0=-2
multiply by x-0 both sides then collect like terms together
it will be y= -2x+4

A dugout needs to reach at least 54 feet below ground level. This means it needs to be more than 214 times its current depth. This depth is represented by the inequality 214d<−54, where d is the current depth of the dugout.
Select from the drop-down to correctly interpret the solution of this inequality.
The current depth of the dugout is

feet below ground level.
Solving the inequality, it is found that:
The current depth of the dugout is of 0.25 feet below ground level.
The current depth of the dugout is of d.
The inequality below represents how much the dugout needs to reach, according to the current depth:
[tex]214d < -54[/tex]
We solve it similarly to an equality, hence:
[tex]d < -\frac{54}{214}[/tex]
[tex]d < -0.25[/tex]
The current depth of the dugout is of 0.25 feet below ground level.

At M & P’s Deli, two pastrami sandwiches and five sodas cost $12.65, while three pastrami sandwiches and two sodas also cost $12.65. How many dollars would seven pastrami sandwiches and twelve sodas cost?
Answer:
37.95
Step-by-step explanation:
MATH
The cost of seven pastrami sandwiches and twelve sodas is $40.08.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that at M & P’s Deli, two pastrami sandwiches and five sodas cost $12.65, while three pastrami sandwiches and two sodas also cost $12.65.
2P + 5S = 12.65
3P + 2S = 12.65
2P + 5S = 3P + 2S
P = 3S
3 x 3S + 2S = 12.65
6S + 2S = 12.65
8S = 12.65
S = $1.58
P = $3.16
The cost of seven pastrami sandwiches and twelve sodas will be:-
Cost = 7P = 12S
Cost = ( 7 x 3.16 ) + ( 1.58 x 12 )
Cost = $41.08
