4 0

Answer:

36

Step-by-step explanation:

the prediction is not big enough so there is not enough sample for such prediction. However based on the probability both are equal to 100

We can say convert from 9/16 to 18/32 and again 36/64 and see we have 100 counters when we use this prediction.

I need help solving this problem.
Galina-37 [17]

Answer:

y = \frac{1}{4} x - \frac{9}{2}

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 )

y = - 4x + 38 is in this form with slope m = - 4

The line ST is perpendicular to line RS ( angles in a square are 90° )

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-4} = \frac{1}{4}

y = \frac{1}{4} x + c ← is the partial equation

To find c substitute (2, - 4) into the partial equation

- 4 = \frac{1}{2} + c ⇒ c = - 4 - \frac{1}{2} = - \frac{9}{2}

y = \frac{1}{4} x - \frac{9}{2} ← equation of ST

The value of x is 1.25 or 1 1/4

Explanation
==============================
275x=500-125x 
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
Hope this helps : )

anzhelika [568]
64 inches is greater than 5ft. There are 12 inches in a foot. You should divide 64 by 12. You will get 5.333 (repeating, in this instance we will round up to 5.4)
