5 because 2/6 of 24 is 8 and the difference of thirteen and 8 is 5
Answer:
374.4
Step-by-step explanation:
All items related to the maintenance are 20% more expensive, it means that each datum is 20% bigger including the average.
The variance its a dispersion measurof the data and its calculated of this way:
Here n is the number of data, is the average and represent each datum. The increment in 20% in each parameter can be represented multiplying for 1.2, of this way
Factorizing the 1.2 we have:
That is:
The new variance is
Answer:
False
Step-by-step explanation:
A quarter coin is half in value of a half-dollar coin. Therefore, two quarters makes up each half dollar coin.
Now, we know that Jessie has 14 half-dollar coins, but she needs quarters to do her laundry. Thus, if each half-dollar coin gives two quarters then 14 half-dollar coins will give quarters.
Thus, if Jessie trades all her 14 half-dollar coins for quarters, she will have 28 quarters for her laundry.
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, then
y = 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = 3x - 7 ← equation of line
