Answer:
$28
Step-by-step explanation:
Given:
data = [22,30,35,25,25,20,27]
For eight night, the new list is:
new_data = [22,30,35,25,25,20,27,x]
Mean = 26.50
Mean Formula:

Therefore:

Multiply both sides by 8:

Solve for x:

Subtract 184 both sides:

Therefore, she will earn $28 in eighth night
The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
Answer:
64.87° = 65°{ to the nearest degree}
Step-by-step explanation:
From the figure Catherine is standing 105m from the point B where the Ballon is; this description fits a= 105 m from the diagram.
Similarly Aisha is standing 95m from the point B where the Ballon is; this description fits c= 95 m from the diagram
A = ? ( The angle of elevation of Aisha towards the balloon)
C = 55°
From Sine rule
It states that the sine of an angle divided by its corresponding side is equal for all corresponding angles and sides along the triangle.
This is expressed mathematically as;
Sin A/ a= SinB/ b= SinC/c
We take the pairs of relevance;
Sin A/ a = SinC/c
There SinA = SinC/c × a
=Sin55/95 × 105
= 0.9053
A = Sin^(-1)[0.9053]
A = 64.87° = 65°{ to the nearest degree}
Answer:
Option C) 0.2358
Step-by-step explanation:
We are given the following data set:
0.23105, 0.4725, 0.8765, 0.4865, 0.5326, 0.7976
Formula:
where
are data points,
is the mean and n is the number of observations.


Sum of squares of differences = 0.1122752556 + 0.008765640625 + 0.09633264063 + 0.006340140625 + 0.001123925625 + 0.05358067562 = 0.2784182787

Thus, the standard deviation for given data is
Option C) 0.2358
Answer:
75 cheeseburgers and 86 french fries
Step-by-step explanation:
This is a guessing math problem so do a random amount and change amount of items to get closer to the answer
81 x 3 = $243
80 x 1.50 = $120
243 + 120 = 363 -354 = 9 dollars
we need nine less dollars so 9/1.5 = 6 so six more fries
86 x 1.5 = 129
75 x 3 = 225
129 + 225 = $354

Answer:
-12w^3 + 30w.
Step-by-step explanation:
–6w(2w^2 - 5) Using the distributive law:
= -6w* 2w^2 - 6w*-5
= -12w^3 + 30w.
