Answer:
The temperature for Sunday was -2.3F
Step-by-step explanation:
When we have a set of N values:
{x₁, x₂, ..., xₙ}
The mean is given by:
[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
In this case, we have the set:
{-5.3F, 3.6F, 6.7F, 0F, 10F, -4.3F, X}
Where X is Sunday's temperature.
So we have a set of 7 values, and we know that the mean of this set is 1.2F
Then we have the equation:
[tex]1.2F = \frac{-5.3F + 3.6F + 6.7F + 0F + 10F - 4.3F + X}{7}[/tex]
If we multiply both sides by 7, we get:
[tex]1.2F*7 = 8.4F =-5.3F + 3.6F + 6.7F + 0F + 10F - 4.3F + X[/tex]
Now we can just solve this for X
8.4F + 5.3F - 3.6F - 6.7F - 10F + 4.3F = X
-2.3F = X
The temperature for Sunday was -2.3F

Answer:
You use the Pytha. theorem to find the length of the missing side or the hypotenuse
Step-by-step explanation:
a^2 + b^2 = c^2
c^2 = the hypotenuse
Answer:
17
Step-by-step explanation:
Use the Pythagorean theorem to solve the problem.
The Pythagorean theorem states A^2 + B^2 = C^2
So, 15^2 (225) + 8^2 (64) = 289
Take the square root of 289. which is 17.

K=1/2mv square root of 2
rearrange for m:
Answer: V = The square root of (2K/M)
We are starting with the formula: K = 0.5MV^2
Our first steps to isolate V would be to multiply by 2 and divide by M on both sides of the equation.
2K/M = V^2
Now, we just have to take the square root of both sides of the equation
The equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.
To rearrange the equation [tex]K = (1/2)mv^2[/tex] for m, we can follow these steps:
Step 1: Multiply both sides of the equation by 2 to remove the fraction:
[tex]2K = mv^2[/tex]
Step 2: Divide both sides of the equation by[tex]v^2[/tex] to isolate m:
[tex](2K) / v^2 = m[/tex]
Therefore, the equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

Your business has two branch stores. The recent physical inventory reports that the merchandise value for each store is: Store A $750,000, and Store B $580,000. The merchandise book value for each store is: Store A $757,000, and Store B $600,000. What is the dollar amount of shrinkage for each store?
Answer: Store A: 7,000 Store B: 20,000
Step-by-step explanation:
The amount of shrinkage for store A is $7000 and for store B is $20000.
What is loss?"If the selling price of an item is less than the cost price, then the difference between the cost price and the selling price of an item is called the loss".
For the given situation,
The merchandise book value for store A = $757,000
The merchandise book value for store B = $600,000
Based on physical inventory reports,
The merchandise value for store A = $750,000
The merchandise value for store B = $580,000.
The amount of shrinkage determines the loss and it is calculated by taking the difference between the values.
Store A = [tex]757000-750000[/tex]
⇒ [tex]7000[/tex]
Sore B = [tex]600,000-580000[/tex]
⇒ [tex]20000[/tex]
Hence we can conclude that the amount of shrinkage for store A is $7000 and for store B is $20000.
