Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Step-by-step explanation:

Hope this is enough to help you understand it, if not then feel free to ask for more info in the comments. :)

Rolls are being prepared to go to grocery stores. Divide 72 rolls into 2 groups so the ratio is 3 to 5.  
Alenkasestr [34]
<span>We need to divide 72 rolls into 2 groups so that their ratio is 3:5. First, we can see that the ratio of 3:5 tells us there is 8 separate groups of rolls. Now its easy, since we have 72 rolls and we need to divide them into 8 equal groups: 72/8=9. So each group has 9 rolls. Now we separate them into groups with the ratio 3:5, so: 3*9:5*9 and that is: 27 rolls and 45 rolls. </span>

The Kansas City Chiefs are trying to figure out if there is a relationship between the number of passes thrown by Quarterback Pa
stich3 [128]

The linear regression equation that represents this data is given as follows: y = 22x - 518.

Using this equation, when 38 passes are thrown, the expected yardage is of 318 yards.

<h3>How to find the equation of linear regression?</h3>

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

In the context of this problem, the input and output are given as follows:

  • Input: number of passes thrown by Patrick Mahomes.
  • Output: number of passing yards obtaining by Mahomes/KC.

The points to be inserted in the calculator are given as follows:

(39, 360), (35, 235), (35, 262), (37, 249), (40, 338).

Hence the equation is given by:

y = 22x - 518.

With 38 passes, the expected yardage is calculated as follows:

y = 22(38) - 518 = 318 yards.

What is the solution to the equation below?<br> log 20x3 - 2log x=4
andrey2020 [161]

Answer:

x=500

Step-by-step explanation:

To solve the equation given, we will follow the steps below:

log 20x³ - 2log x=4

using the law of logarithm,

2log x = log x²

so, our equation becomes;

log 20x³ - log x²=4

Also using another law of logarithm;

log 20x³ - log x² = log (20x³/x²)

our equation becomes;

log (20x³/x²) = 4

log 20x = 4

from the definition of logarithm, logarithm is the power of the exponential

10⁴ = 20 x

10000 = 20x

divide both-side of the equation by 20

10000/20 = 20x/20

at the right-hand side of the equation 20 will cancel-out 20 leaving us with just x  and the left-hand side of the equation, 10000 will be divided by 20

500 = x

x = 500
