linear equation in slope intercept form for this situation. mary is selling popcorn for $5.00 per bucket and hotdogs for $4.75 e
3241004551 [841]

Answer:

standard form to represent the situation equation is 5a + 4.75b = 72.50

Step-by-step explanation:

given data

selling popcorn = $5.00

hotdogs = $4.75

makes =  $72.50

solution

we consider here number of bucket sold = a

and number of hotdogs sold = b

Then after 1 hour she makes $72.50

equation for number of popcorn and number of hotdogs sold after an 1 hour  is express as

$72.50 = number of bucket sold × price of popcorn per bucket + number of hotdogs sold × price of hotdog   ...............................1

put here value and we get

72.50 = 5 × a + (4.75) × b  

5 a + 4.75 b = 72.50

so here equation is equivalent to the standard form in the  linear equation that is express  ( Ax + By = C   )

and here A and B are non zero with  A, B and C all three are real number

so standard form to represent the situation equation is 5a + 4.75b = 72.50

The sat scores have an average of 1200 with a standard deviation of 120. a sample of 36 scores is selected. what is the probabil
Naya [18.7K]
We first standardise \bar{x}:
P(1224 > \bar{x})=P(\frac{1224-1200}{\frac{120}{ \sqrt{36} }}>\frac{\bar{x}-1200}{\frac{120}{\sqrt{36}}})
which reduces to finding P(Z > 1.2) = 0.115

Will the opposite of a number always,sometimes,or never be greater than the number itself?
Dima020 [189]
Sometimes, because if you have a negative number than the opposite is positive and more. Then if you have a positive number it will be negative and therefore less.
